Certain commercial entities, equipment, or materials may be identified in this document in order to describe an 

experimental procedure or concept adequately. Such identification is not intended to imply recommendation or 

endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, 

materials, or equipment are necessarily the best available for the purpose.

Abstract

The 98th Annual Meeting of the National Conference on Weights and Measures (NCWM) was held 

July 14 -18, 2013, at the Seelbach Hilton Louisville, Louisville, Kentucky. The theme of the meeting was 

“On the Path to Tomorrow.”

Reports by the NCWM Board of Directors, Standing Committees, and Special Purpose Committees 

constitute the major portion of this publication, along with the addresses delivered by Conference officials 

and other authorities from government and industry. 

Special meetings included those of the Scale Manufacturers Association, Meter Manufacturers 

Association, Packaging and Labeling Subcommittee, Task Group on P rinter Ink and Toner Cartridges, 

Fuels and Lubricants Subcommittee, Associate Membership Committee, Taximeter Technology 

Advancements, and Making Sense of Electronic Receipts. 

Key words: laws and regulations; legal metrology; meters; scales; specifications and tolerances; training; 

type evaluation; uniform laws; weights and measures.

Note: The policy of the National Institute of Standards and Technology is to use metric units of measurement in all 

of its publications. In this publication, however, recommendations received by the NCWM technical committees 

have been printed as they were submitted and, therefore, may contain references to inch-pound units where such 

units are commonly used in industry practice. Opinions expressed in non-NIST papers are those of the authors and 

not necessarily those of the National Institute of Standards and Technology. Non-NIST speakers are solely 

responsible for the content and quality of their material.

Chairman’s Address

National Conference on Weights and Measures

Louisville, Kentucky

July 16, 2013 

Stephan Benjamin

North Carolina Department of Agriculture and Consumer Services

Thank you Commissioner Comer and Dr. May for being with us today:

Good morning and welcome to the 98th Annual Meeting of the National Conference on Weights and Measures

(NCWM). It has been my honor and privilege to serve as Chairman this past year. I’ll admit it has been a challenge 

at times, but it has been a rewarding experience. 

My theme this year was “On the Path to Tomorrow.” With that in mind, I would like to briefly review some of the 

accomplishments of NCWM this past year. We just launched our new website, which has a number of new features 

and is friendly to mobile devices. The Professional Certification Program launched two new tests, Small Capacity 

Weighing Systems Class III and Package Checking Basic and they are working on two more. We have advertised 

for a new staff position that will allow for the expansion of the VCAP program and provide another option for 

NTEP evaluations. 

I have mentioned some of these items as I attended the regional meetings this year. While there, I often heard a 

comment or two about membership. How the number of members has declined the last few years along with the 

budgets of the weights and measures programs as well as our industry members. The Board of Directors has worked 

for a number of years to make improvements in our services and benefits, in part, to make membership attractive; to 

make it of value to a member. While membership numbers are great, what keeps us successful is participation. 

This is most obvious with the Standing Committees and the Board of Directors, as we sit before you through open 

hearing and voting sessions. Then we have our Subcommittees, the NTEP Sectors, Work Groups and Task Groups. 

You will find a list of these willing participants in the front of each Publication 15 and 16. In the last newsletter, 

there was a list of Subject Matter Experts or SMEs that have contributed to the Professional Certification Program. I 

would even extend this list of participants to the Regional Associations as they mirror the NCWM structure.

My point is that participation is critical to this organization. There are many places for you or members of your staff 

to contribute, even if one cannot attend the Interim or Annual meetings. The SMEs and NTEP Sectors are excellent 

examples of this and include a good mix of regulators and industry. NCWM and National Institute of Standards and 

Technology (NIST), Office of Weights and Measures (OWM) have the ability to host conference calls and webmeetings. These have been used by Work Groups and Task Groups which has allowed for a lot of work to be done 

between meetings and involve new people who otherwise could not attend.

So, I would like to thank all of you that have stepped up and participated in one or more of the many committees, 

subcommittees or other groups within NCWM and the Regional Associations, and I hope you continue to do so. I 

would encourage all of you to seriously consider accepting one of these roles if you are asked; or volunteering for 

one if you have an interest or expertise. It is also an opportunity to both learn and teach. 

The newly formed Training Manual task group, for example, is in need of members. Their efforts are 

complimentary to the Professional Certification Program, so it would benefit many outside this room when they are 

successful with their task. 
General – 2013 Final Report

Chairman’s Address

GEN - 24

Don’t be shy! I was the manager of our fuel quality program when I became the Director of the Standards Division 

in August 2004. I knew very little about the Conference then. I had attended one Interim Meeting in January2005 

before I was asked to serve on the Laws and Regulations Committee. I will admit I hesitated to accept the 

appointment. However, I decided what better way for me to learn this new world of weights and measures and start 

making contacts with my peers and industry. Participation is part of where the NCWM’s strength lies.

In closing, what we do here at NCWM, both at this meeting and outside of it, in our committees and work groups, is 

a team effort. I would like to thank the membership and the Board of Directors for their support this past year. The 

NCWM staff went through a lot of changes, but they were always professional and accomplished their goals. Thank 

you to our Associate Members and Measurement Canada as they actively participate in our processes. Finally, I 

would like to recognize our partners in the NIST Office of Weights and Measures, for without their technical 

expertise and daily work in the areas of Weights and Measures and Legal Metrology we would be hard pressed to 

move forward on many of the issues that come before us. 

Thank you all for allowing me to be your chairman this past year and I look forward to working with John this 

coming year.

National Conference on Weights and Measures

Louisville, Kentucky

July 16, 2013 

John Gaccione

Westchester County, New York

Good morning and thank you.

I begin by thanking Steve Benjamin. Steve made being Chairman look easy. But the reality is that Steve never 

stopped working for the National Conference on Weights and Measures (NCWM). NCWM continues to be a wellrespected organization because of Steve. Thank you, Steve, for all of your guidance in preparing me in my new role 

as NCWM Chair.

I would also like to thank all the members of the Conference for electing me Chairman of NCWM. I am humbled, 

and it is an honor I do not take lightly.

More thanks go to Kurt Floren and Tim Tyson for their advice and help. And to all the previous chairpersons for 

their hard work and dedication in bringing the Conference to where it is today, an organization that is respected, 

recognized, and a model for other organizations on how to get things done.

Thank you NCWM staff: Don, LuAnne, Elisa, and Jim. Everyone should take a moment to see how much they do 

and how well they do it. And thanks also go to Carol Hockert and the National Institute of Standards and 

Technology (NIST) staff for their never ending assistance.

With that, I promise I will be brief, “not boxers,” briefs.

Going slightly off course, I wanted to share with everyone a column that some of you may have seen, but what it 

says is important. 

It appeared in the “About.com Guide” (http://moneyover55.about.com/b/2012/08/13/weights-measures-and-theelection.htm), August 13, 2012. 

Weights, Measures, and the Election 

by Dana Anspach, she writes:

As I'm driving to work today the radio morning show began talking about my state's Weights and 

Measures Department. Apparently they go around testing gas pumps to see if in fact we are 

getting what we pay for at the pump. I had no idea such a department existed. The conclusion? 

Of the pumps tested about 200 some pumps were overcharging... but 800 were giving us more 

than we paid for.

Until I heard this, it never even crossed my mind to wonder if I was being ripped off at the gas 

pump. How the heck would I know if in fact 16.3 gallons was delivered? I simply trusted the 

system.

It wasn't until this morning's drive that it hit me that the reason I can trust the system is because 

some of my tax payer dollars pay for the Weight and Measures department. I wonder how many 
General – 2013 Final Report

Chairman Elect’s Address

GEN - 26

other things my tax payer dollars pay for that I am simply unaware of, and would in fact, be in 

favor of?

Words well written and worth repeating. Spread the word.

Today we face challenges that were never dreamed about 10 or 15 years ago.

Right now you can:

• Catch up on television news, order lunch and earn points towards future purchases while filling up at the 

gas pump. 

• Fuel up with an “alternative” to good old gasoline and diesel.

• Stand in an aisle in a store and compare prices with other nearby stores and on t he Internet, and read 

consumer reviews about a product.

• Go into a grocery store, scan and bag your own purchases long before you reach the cashier. Or from 

home, place an order with the supermarket or grocery store and have it delivered to your door step.

• Track a purchase on its long journey from its supplier to your home.

• Charge your electric vehicle while at your workplace or at transportation hub or while shopping.

• Look at the label on an item and know not just its weight and who packaged it, but its nutritional value, its 

country of origin and under what conditions it was grown, prepared, and packaged. 

• Encounter a new method of sale for how a commodity is sold.

Every day, we see how rapidly change occurs. 

NCWM must be ready to meet these new challenges. 

While we continue to ensure a fair and equitable marketplace, we must recognize that change and new technology 

arrive at a much faster pace than it did in the past. 

With that my theme for the coming year is “Meeting Tomorrow’s Challenges Today.” 

I constantly remind my own staff that “change is good”. Change is not easy. 

Change many times leads to a new, more efficient way of getting things done. Change allows the formulation of 

new ideas. Change allows us to meet tomorrow’s challenges.

Paraphrasing President John Kennedy, “We chose to do things, not because they are easy, but because they are hard, 

because the results will measure the best of our energies and skills.”

Are we ready for those new challenges? I believe we are; with everyone’s participation, NCWM is ready to meet 

new challenges. 

Thank you all, please arrive home safely, and see you in Albuquerque.

Mr. Stephen Benjamin, Chairman

North Carolina

100 INTRODUCTION

This is the report of the Board of Directors (hereinafter referred to as the “Board”) for the 98th Annual Meeting of 

the National Conference on Weights and Measures (NCWM). This report is based on the Interim Report offered in 

the NCWM Publication 16, testimony heard at public hearings, comments received from the regional weights and 

measures associations and other parties, the addendum sheets issued at the Annual Meeting, and actions taken by the 

membership at the voting session of the Annual Meeting. The Informational items presented below were adopted as 

presented when the Committee’s report was approved.

Table A identifies the agenda and appendix items. Agenda items are identified in the Report by Reference Key Number, 

Item Title, and Page Number. Item numbers are those assigned in the Interim Meeting agenda. A Voting item is indicated 

with a “V” after the item number. An item marked with an “I” after the reference key number is an Informational item. 

An item marked with a “D” after the reference key number is a Developing item. The developing designation indicates an 

item has merit; however, the item was returned to the submitter for further development before any action can be taken at 

the national level. An agenda “Item Under Consideration” is a statement of proposal and not necessarily a 

recommendation of the BOD. Suggested revisions are shown in bold face print by striking out information to be deleted 

and underlining information to be added. Table B lists the results of any Voting Items.

Note: It is the policy to use metric units of measurement in publications; however, recommendations received by NCWM 

technical committees and regional weights and measures associations have been printed in this publication as submitted. 

Therefore, the report may contain references to inch-pound units.

110 ACTIVITY REPORTS

110-1 I Membership and Meeting Attendance

Membership levels remain fairly steady, not yet rebounding to levels experienced before the decline in the economy 

and organizational budgets. 

NEWMA members support continued outreach to other organizations such as the presentation Mr. Jim Truex 

provided to International Society of Weighing and Measuring (ISWM) this year. Associate Membership Committee 

(AMC) members are in a position to draw in more members from other industries, too. A member commented that 

the NCWM Board should be more aggressive to get new members. There was concern for maintaining a quorum at 

the Annual Meeting during continued economic stress. Special deals or professional recruitment may make sense to 

get more members to attend Annual and Interim Meetings. NEWMA supports the development of a toolkit to help 

jurisdictions garner legislative support and avoid privatization of weights and measures programs (see Item 110-5). 

The Professional Certification Program should get more people involved and that may increase membership.

The Board recognized that the pool of potential members, especially regulatory officials, has significantly decreased 

as a r esult of downsized or eliminated programs resulting from budget cuts. T he Board does believe that 

membership levels will significantly increase once the Professional Certification Program is fully developed and can 

be referenced for registered service agencies and inspector pay grades. The price structure for the exams is set to 

heavily favor membership as an alternative to paying non-member exam fees.

The following is a comparison of NCWM membership levels for the past ten years.

Annual Membership Totals

The attendance for the 2012 and 2013 Interim Meetings in New Orleans, Louisiana, and Charleston, South Carolina,

respectively was very strong. Attendance also improved for the 97th Annual Meeting, in Portland, Maine, and those 

levels were maintained very closely for the 98th Annual Meeting in Louisville, Kentucky. Participation has been

very good for the Sunday afternoon special work sessions of Subcommittees and Task Groups. These sessions 

benefit the standards development process, and add value for stakeholders who attend Interim and Annual Meetings. 

See Item 110-3 for information on future meetings.

110-2 I NCWM Newsletter and Website

Newsletter:

The Board continuously considers ways to monitor and improve the content of the newsletter and website. 

Members are encouraged to bring ideas and articles forward for inclusion in newsletters. Of particular interest are 

articles that would be pertinent to field inspectors and the service industry.

Website Improvements:

At the 2012 Annual Meeting, the Board of Directors approved a number of enhancements to the website. Some of 

these new features include: 

• Add a mobile-friendly version for popular features including the NTEP database search; 

• Add the option of instant PDF download for NCWM Publication 14 sales; 

• Add the ability to apply online for NTEP certification; 

• Improve the shopping cart experience; and

• Full website integration with the Professional Certification Program testing site for an automated customer 

experience. 

The new website was functional in May 2013. 

NEWMA voted to invest $1,500 to add online meeting registration and dues payments to their website as part of the 

project scope for NCWM’s new website. T hat project is complete and now all four regional associations have 

ecommerce using NCWM’s merchant services account for credit card processing. 

Many members have expressed appreciation for the mobile-friendly version for searching and downloading NTEP 

Certificates of Conformance in the field via smart phones etc., noting that field officials probably visit that area of 

the website more often than any other. There was a suggestion that the website include a list of duties for each staff 

person and provide a welcome and introduction to new staff persons. 

A member asked that all of the safety articles from past newsletters be posted in one location on the website for 

easier access to download. T his request has been implemented and the articles may be accessed 

at: www.ncwm.net/resource/safety/articles. 

Comments and suggestions for improvements to the newsletter and website should be directed to NCWM at 

(402) 434-4880 or info@ncwm.net. 

Online Position Forum: 

The purpose of the Online Position Forum is to help members prepare for the deliberations and voting at the Annual 

Meeting in July by having a better idea of positions others may have.

Activity on the site increased somewhat in the second year for the Online Position Forum, but it remains light. The 

Board believes that participation will increase in time as members become more comfortable with it and as 

committee agenda items generate interest. Improvements were made following the first experience in 2011 so that 

comments are more easily viewed.

The Online Position Forum is not a voting system. Comments and positions entered there are not binding. It is 

simply a method to present positions, opinions, and supporting documents. All active, associate, and advisory 

members have the opportunity to login, view committee agenda items, enter positions and comments, and even 

upload supporting .pdf documents for each agenda item of standing committees or the Board. 
BOD 2013 Final Report

BOD - 6 

NCWM notifies members when the forum is ready for them to enter their comments each spring. The comment 

period will end on May 31. The options for each agenda item are:

• Support; 

• Support with Comments; 

• Oppose with Comments; 

• Neutral; or

• Neutral with Comments. 

Beginning in 2014, the Forum will be reconfigured so that members can view the comments and positions that 

others have submitted prior to submitting their own. H owever, the site is not a blog. O nce a member submits 

positions, that member cannot submit more positions. 

NEWMA supports continuing the Online Position Forum and remains hopeful that more members will participate in 

the future. 

Social Networking: 

Over the past year, NCWM has posted many news articles and other items of interest to the weights and measures 

community on the social networks. T his has increased interest in the social network accounts with LinkedIn, 

Facebook, and Twitter. These accounts were formed to improve NCWM’s outreach and raise awareness of our 

organization. By opening these accounts, NCWM is now more visible in internet search engines and will be more 

identifiable to tech-savvy stakeholders. They will find links to weights and measures related news stories and they 

will be kept informed throughout the Interim and Annual Meetings of special announcements including any changes 

in schedule. Members who participate in these social networks are encouraged to follow NCWM as a means of 

creating even more exposure with their friends and colleagues. 

Compliments were offered to NCWM for posting links to pertinent news pieces related to weights and measures on 

the NCWM Facebook, LinkedIn, and Twitter accounts and to NIST for posting them to the Directors e-mail listserv. 

Professional Certification Program: 

Individuals may submit requests for NCWM Professional Certification Exams at www.ncwm.net. Exams are free 

for members and $75 for non-members. The NCWM website is now fully integrated with the online testing service. 

As orders are received, the applicant receives an automated e-mail with credentials and instructions for accessing the 

exam. An applicant who does not pass the exam in the first attempt may have one retake. After that, it will be 

necessary to reapply. 

NEWMA noted that the Professional Certification Program is a tremendous opportunity for training and education. 

Members are looking forward to additional exams.

Certification is now available in three areas, including:

• Retail Motor Fuel Dispensing Systems; 

• Package Checking Basic; and

• Small Capacity Weighing Systems Class III. 

See the Professional Development Committee Report for information on additional exams under development.

110-3 I Meetings Update

Interim Meetings:

• January 19 - 22, 2014 Hotel Albuquerque, Albuquerque, New Mexico

• January 18 - 21, 2015 Hilton Daytona Beach, Daytona Beach, Florida

• January 2016 Hotel to be selected in San Diego or Orange County, California
BOD 2013 Final Report

BOD - 7 

Annual Meetings:

• July 13 - 17, 2014 The Westin Book Cadillac Hotel, Detroit, Michigan

• July 19 - 23, 2015 Sheraton Society Hill Hotel, Philadelphia, Pennsylvania

NCWM strives to plan meetings in locations that offer comfortable rooms and a variety of entertainment and dining 

options close by. The following is a brief description of future planned events.

The 2014 Annual Meeting will be held at the Westin Book Cadillac Hotel in downtown Detroit, Michigan. This 

Italian Renaissance-style hotel is in the National Register of Historic Places. There are restaurants in the area to 

assure attendees of evening enjoyment. 

The Board has selected Philadelphia, Pennsylvania, for the 100th NCWM Annual Meeting in 2015. The Sheraton 

Society Hill Hotel provides easy access to the rich history and evening food and entertainment.

The top three cities for the 2016 Interim Meeting were ranked in order of preference by the Board with San Diego, 

California; first, Orange County/Los Angeles, California, area; second, and Phoenix, Arizona; third. I f there is 

enough competition in San Diego to secure desired rates, NCWM will limit site visits to that city.

100th NCWM Annual Meeting: 

The Board hopes to make the 2015 Annual Meeting a very special event and one that you won’t want to miss. In 

addition to addressing the business of the organization, NCWM will be celebrating its 100th Annual Meeting; 

110 years after our first meeting in 1905. A small work group is developing plans for the 100th NCWM Annual 

Meeting in 2015. Originally, the Board looked at Washington, DC, Boston, Massachusetts, and Philadelphia, 

Pennsylvania, because of their historic significance. At NEWMA’s request, proposals were also requested from 

Baltimore, Maryland. The final decision was the Sheraton Society Hill in Philadelphia. The Work Group will 

consider special events to commemorate and bring excitement to the occasion. Suggestions may be forwarded to 

Ms. Elisa Robertson, NCWM Office Manager, at (402) 434-4872 or elisa.robertson@ncwm.net. 

110-4 I Participation in International Standard Setting

Conformity to Type

International Organization of Legal Metrology (OIML) is considering development of a Conformity to Type (CTT) 

program. An OIML Seminar on CTT was held in June 2011 in Utrecht, The Netherlands. NCWM was invited to 

share its experience with the NTEP Conformity Assessment Program and in particular, the Verified Conformity 

Assessment Program (VCAP). The presentation was given by Mr. Onwiler, NCWM Executive Director. NCWM is 

hopeful that the VCAP Audit Reports can also satisfy the needs of the OIML CTT at a s ignificant savings to 

certificate holders. Mr. Flocken, Mettler-Toledo, LLC, made a p resentation with perspectives from the 

manufacturing industry. Dr. Ehrlich, National Institute of Standards Technology (NIST), Office of Weights and 

Measures (OWM), was in attendance and participated in the discussions. An OIML subcommittee has been formed 

to research and make recommendations on the development of an OIML CTT program.

Mutual Acceptance Arrangement (MAA)

Mr. Truex, NTEP Administrator, attended the Committee on Participant Review in Germany in 2011. Resolutions 

were developed at that meeting for the amendment of B10, the certificate system under the MAA. The spirit of the 

resolutions was to allow utilizing authorities to voluntarily accept manufacturer test data under the MAA. The 

resolutions were adopted in 2012. (See the NTEP Committee Interim Meeting Report for more detail and Board of 

Director’s Report, Appendix A.) 

Dr. Ehrlich, NIST, OWM, gave a report of OIML activities at the 2013 NCWM Interim Meeting. Mr. Ralph Richter 

gave a report of the OIML activities at the 2013 NCWM Annual Meeting in Louisville, Kentucky. This report is 

included as an Appendix A to the Report of the Board of Directors 
BOD 2013 Final Report

BOD - 8 

110-5 I Associate Membership Committee (AMC) Activity 

The Associate Membership Committee is organized in accordance with the Bylaws of the National Conference on 

Weights and Measures, Inc. In addition, AMC operates by its own Bylaws which are available on the Committee

pages of www.ncwm.net. AMC meets at least two times per year in conjunction with NCWM Interim and Annual 

Meetings. It consists of between 5 and 10 members who, amongst themselves, elect officers to serve as Chairman, 

Vice Chairman, and Secretary/Treasurer. AMC has established a reputation of promoting and improving NCWM 

and has demonstrated its desire to improve understanding of weights and measures activities in public and private 

sectors.

The membership dues for Associate members ($90) are higher than that for Active or Advisory members ($75). The 

extra $15 is not for NCWM, but rather is placed in a separate account referred to as the AMC Training Fund. AMC 

receives applications and awards training scholarships in accordance with their “Guidelines for Selection and 

Approval of Training Funds” that are posted on the Committee’s portion of www.ncwm.net. Downloadable 

scholarship applications and reimbursement forms are also available there or applications may be made online. 

AMC training fund selection criteria are as follows:

1. Training fund request forms that are complete, specific, and detailed will receive priority attention for 

approval. Based on the degree of missing or ambiguous information provided, individual requests may not 

be given any consideration during the AMC review process.

2. Training requests that benefit higher numbers of participants are generally preferred over those for fewer or 

single-person benefit. Multi-state training that encourages uniformity will also be given priority 

consideration.

3. In general, attending meetings will not be considered training, especially requests for travel expense or 

attendance fees for NCWM Annual, Interim, or Regional meetings.

4. As a l ower priority, requests for the purchase of training materials will be considered, but requests for 

purchase of assets (such as LCD projectors) will not.

5. Reasonable funding for travel and expenses will be considered if it is necessary to acquire an “expert 

trainer” that would benefit a high number of weights and measures officials. This will be an option when 

qualified volunteers are not available.

Members of AMC have become concerned that the funds are underutilized in recent years. Regulatory agencies are 

encouraged to make use of these funds to improve training opportunities and the expertise of inspection personnel. 

AMC members are also looking for new, perhaps innovative ways to play a more effective role in the NCWM 

structure in an effort to further improve the organization. Some new initiatives that AMC is discussing include:

• Promotional Tool-Kit: AMC has offered funds to assist NCWM in creating a “tool kit” that weights and 

measures administrators could use to improve awareness and support through adequate funding of their 

programs. T his tool kit could consist of many elements for targeting media, consumers, government 

administrators, and legislators. AMC has proposed a work group to pursue this project.

• Tradeshow Seminars: AMC is interested in organizing training or awareness seminars at industry type 

tradeshows with the idea of reaching out to the smaller industry groups that are impacted by the work of 

NCWM. This effort would be good for the smaller industries as well as providing possible increase in 

NCWM membership and participation.

AMC meetings are open to all registered NCWM meeting attendees. All Associate Members are encouraged to 

attend these meetings, become familiar with the Committee, and offer ideas for how it can further pursue its 

objectives. (See Appendix B of the Board report for the AMC Meeting Minutes.)
BOD 2013 Final Report

BOD - 9 

The NEWMA Board of Directors has expressed appreciation specifically for the support that the AMC has provided 

through training funds, and they look forward to the development of the Promotional Toolkit.

120 STRATEGIC PLANNING, POLICIES, AND BYLAWS 

120-1 I Strategic Planning

The Executive Director presents a strategic plan progress report each year at the fall Board meeting. The Board

conducts a strategic planning session in January at its quarterly meeting just prior to the Interim meeting. The Board 

made several updates and changes to the Strategic Plan in January 2013. Members are able to review the Strategic 

Plan at online at www.ncwm.net. NEWMA has pledged assistance for NCWM to achieve its goals. The Board 

welcomes member input. 

Five NCWM Strategic Plan Goals:

1. Enhance NCWM as a national and international resource for measurement standards development.

2. Expand the role of NCWM as a resource for state and local weights and measures programs.

3. Promote uniform training for individuals involved in weights and measures.

4. Continue to improve NTEP.

5. Preserve the financial stability of NCWM.

NCWM as a National and International Resource:

Strategy 1: This goal was initially to implement the Online Position Forum. That was completed in 2011 and the 

strategy is now to make improvements to the program and promote increased use of it by our membership. Several 

ideas have been implemented to generate interest. Additionally, guidance has been developed to assist committees 

in how to preview and use comments in a consistent manner. 

The following new strategies were added to this goal:

Strategy 2: Identify, communicate and collaborate with other regulatory, industry, and standards development 

organizations, foreign and domestic, to strengthen awareness of NCWM and draw on mutual resources toward 

mutual goals.

Strategy 3: Increase consumer group participation in NCWM through outreach efforts.

Expand the Role of NCWM as a Resource to Officials:

Initially, a strategy under this goal was to conduct annual surveys of the states to gather specific information for 

benchmarking purposes. In 2013, the strategy was modified to provide flexibility on the frequency and subject 

matter for surveys. 

Many programs are experiencing severe budget cuts that are diminishing their effectiveness. T he AMC has 

expressed interest in assisting with the development of a “tool kit” that can be used by program administrators to 

generate awareness and support for their programs. This toolkit will contain materials including data supporting a 

regulatory presence, industry contacts that can be called upon to explain the necessity of a regulatory presence to 

ensure a level playing field for businesses and consumer protection, and a short video production.

Promote Uniform Training: 

The Professional Certification Program is a top priority under this goal. Two new exams were added in 2012 and 

several more are in development. Mr. Ross Andersen continues to serve as Certification Exam Coordinator working 

with the PDC and subject matter experts. The Board believes this arrangement will greatly assist the PDC in 

developing a full line of certification exams.

Some states are expressing interest in using the Professional Certification Program as a p rerequisite to 

registering/licensing service agents. There is discussion that the exams may be more difficult for service agents who 

have not received the level of Handbooks 44 (Specifications, Tolerances, and Other Technical Requirements for 
BOD 2013 Final Report

BOD - 10

Weighing and Measuring Devices), 130 (Uniform Laws and Regulations in the Areas of Legal Metrology and 

Engine Fuel Quality), and 133 (Checking the Net Content of Packaged Goods) training that regulatory officials 

receive. If the exams are too difficult, it could provide a costly delay to service agencies that are trying to establish 

employees as qualified to work independently and with the privileges of being registered or licensed. The counter 

argument would be that the Professional Certification Program should elevate concerns over the quality of service 

agents as well as regulatory officials. See more discussion on this in the PDC report. 

Several amendments were made to the various strategies in this goal and a new strategy was added to create a 

national directory of weights and measures officials at all levels of government. NCWM will need to determine an 

effective method to compile the information. 

Continue to Improve NTEP: 

NCWM surveyed regulatory officials this past year to determine how they access NTEP Certificates of 

Conformance in the field. This will be used as a benchmark. As technology advances, NCWM will have a better 

understanding for how it can make Certificates of Conformance more accessible. I n 2013, NCWM will offer a 

mobile friendly version of the website which will benefit those who access the NTEP database with their smart 

phones.

A strategy of high priority under this goal is to maintain viable support for NTEP laboratories. Mr. Truex, NTEP 

Administrator, monitors the number of full-time equivalents associated with the authorized laboratories and tracks 

evaluation time and backlog statistics to ensure that NTEP evaluations can be completed in a timely manner. He 

reports these statistics quarterly to the NTEP Committee and Board of Directors.

NCWM has a contingency plan in place to ensure evaluation services are maintained for NTEP applicants in the 

event that insufficient services were available under the current authorized laboratory system. The Board is 

monitoring its available resources toward that end in hopes that NCWM will eventually be in a position to 

implement the worst-case scenario, should the need arise. Another strategy toward this goal is the continued 

development of the Verified Conformity Assessment Program which has already successfully addressed load cells

and has moved on to the next device-type category. (See the NTEP Committee Report for more details.) 

Preserve Financial Stability: 

This goal was originally to “ensure” financial stability. F inancial reports of the past several years indicate that 

NCWM is financially stable barring any unexpected circumstances. However, NCWM must recognize that it does 

not have sufficient reserves at this time to fully implement the NTEP contingency plan that was developed to ensure 

continued evaluation services if the authorized state laboratories fell victim to budget cuts. The Board has studied 

NCWM’s needs for reserves for NTEP and other potential exposures. This is being balanced with continued efforts 

to improve services in support of customers and membership. NCWM finances are reviewed annually. 

120-2 I Regional Support

Meeting Documents on Regional Websites:

In the fall of 2011, NCWM made efforts to be the clearinghouse for all new proposals being submitted to the 

regional associations. Since then, staff has been looking for ways to further streamline the process while improving 

documents, reports, and communication. NCWM provides the regional committees with a report template that 

contains all of the regions carryover items and new proposals. The templates are improved each year based on 

feedback and efforts to streamline the reporting process for everyone. 

The report templates in 2013 have been modified based on extensive discussions at the 2012 Committee Orientation 

sessions. Regional committees should find them to be less confusing for presenting the discussions, 

recommendations, and regional decisions. NEWMA committee chairs expressed that the process is now much 

easier to work with and also members have a clearer understanding of the issues. Downloading agenda items for 

interim and annual meetings is made much easier. They also stated that the new format for NCWM Publication 15 

works very well and the deadline works well. 

All of the regional websites are hosted through NCWM. NCWM has worked in recent years with the website 

company to add ecommerce to the regional websites using NCWM’s merchant services to process credit card 
BOD 2013 Final Report

BOD - 11

payments. T his additional programming is at the regions’ expense, but there is no additional administrative fee 

above the standard flat rate of $200 per year assessed by NCWM to provide support. As of 2013, all four regions 

have now added the ecommerce option for online meeting registrations and membership dues (where applicable). 

NEWMA Board of Directors expressed appreciation for the efforts of NCWM staff to update regional websites for 

all committee issues and making the process of filling out Form 15 for submitters much easier and clearly 

understood. 

120-3 I Standing Committees Support

Committee Orientation:

NCWM conducts Committee Orientation for committee chairs and new committee members every fall at NIST, 

OWM in Gaithersburg, Maryland. The location enables full participation by all NIST Technical Advisors. The 

focus is on l eadership, administrative processes, roles and responsibilities, and review of NCWM Committee 

Handbook. Additionally, the Committee chairs and NIST Technical Advisors review agenda items for the new 

members so that they are prepared in advance for the technical discussions and Open Hearings.

At the 2012 Committee Orientation, additional improvements were made to the NCWM Committee Handbook and to 

the report templates that regional committees use to submit their reports for inclusion in NCWM Publication 15.

Task Groups, Subcommittees, Steering Committees: 

Task groups, subcommittees and steering committees are created by appointment by the NCWM Chairman. A task 

group is given a specific charge and it reports to the appropriate NCWM standing committee. A task group will 

disband at the completion of its assignment. A subcommittee is charged with ongoing responsibilities in support of 

a standing committee in a specific field of expertise. A steering committee is charged with unbiased fact-finding 

that will assist NCWM membership in decision processes for difficult issues. A steering committee will disband 

upon completion of its specific charge.

NCWM offers resources to these task groups and subcommittees including meeting space at Interim and Annual 

Meetings, conference calling and web meeting services, dedicated e-mail listservs, a dedicated web page for posting 

and archiving documents related to their work, and broadcast e-mail services to reach targeted audiences. 

Additionally, NIST, OWM has provided technical advisors and web meeting forums. All of these tools enable yeararound progress of task group and subcommittee work.

Because NCWM task groups and subcommittees report directly to NCWM Standing Committees or Board of 

Directors, any new proposals may appear in NCWM Publication 15 without first being vetted through a regional 

association. Any such proposals are properly vetted through the open hearings of NCWM. This structure enables 

more efficient standards development. 

Two new groups are being established this year; the Promotional Tool Kit Task Group and the Natural Gas Steering 

Committee. Descriptions are provided below.

The Board expresses great appreciation to the volunteers who serve in support of the work of this organization.

• Natural Gas Steering Committee (NEW):

The Laws and Regulations (L&R)Committee heard spirited debate at the 2013 Interim Meeting Open 

hearings on a proposal to recognize the Diesel Gallon Equivalent and Diesel Liter Equivalent as the method 

of sale for compressed and liquefied natural gas; similar to the Gasoline Gallon and Liter Equivalents that 

were recognized in 1994. Opponents argue that a method of sale by mass is preferred. 

NCWM Chairman Stephen Benjamin formed a new Natural Gas Steering Committee to address rising 

issues as the compresses and liquefied natural gas markets rapidly expand. The Steering Committee will 

report to the Laws and Regulations Committee. Its charge is to gather information that will assist NCWM 

Membership in the decision process as model standards are developed for the sale of compressed natural 

gas.

120-4 V Section L. Classifications for Agenda Items, Section M. Developing Items 

(This item was adopted.) 

Source: 

NCWM Board of Directors (2013)

Purpose: 

Clarify definitions of agenda item status designations. 

Item Under Consideration: 

Amend NIST Handbook 44, Specifications, Tolerances, and Other Technical Requirements for Weighing and 

Measuring Devices and NIST Handbook 130, Uniform Laws and Regulations in the Areas of Legal Metrology and 

Engine Fuel Quality Introduction as follows: 

L. Classifications for Agenda Items.

At the Interim Meeting, the Committee canwill classify proposals in one of the following ways as:

1. “Voting” – these are items proposed for a vote by the NCWM membership and are indicated 

with a “V” after the item number in the agenda These are items the Committee believes are fully 

developed and ready for final consideration of the voting membership. Each item has either 

received majority support from the Committee or the Committee has reached agreement that it 

is ready for voting status to let NCWM membership decide. The Committee has the ability to 

remove items from the voting agenda at the Annual Meeting by changing the status prior to a 

vote of the NCWM membership. The Committee may amend voting items during the course of 

the Annual Meeting based on additional information received following the Interim Meeting and 

testimony received at the Annual Meeting. These items may also be amended by the voting 

membership during the voting session of the Annual Meeting following the procedures outlined 

in the NCWM Bylaws; or

2. “Informational” – these are items which require further study, comment, and development and 

are indicated with an “I” after the item number in the agenda These items are deemed by the 

Committee to have merit. They typically contain a proposal to address the issue at hand and a 

meaningful background discussion for the proposal. However, the Committee wants to allow 

more time for review by stakeholders and possibly further development to address concerns. 

The committee has taken the responsibility for any additional development of Informational 

items. For particularly difficult items, the Committee may assign the item to an existing 

subcommittee under its charge or request that the NCWM Chair appoint a special task group 
BOD 2013 Final Report

BOD - 14

that reports to the Committee. At the Annual Meeting, the Committee may change the status of 

the items, but not to Voting status because the item has not been published as such in advance of 

the meeting; or

3. “Developing” - These items are deemed by the Committee to have merit, but are found to be 

lacking enough information for full consideration. Typically the item will have a good 

explanation of the issue, but a clear proposal has yet to be developed. By assigning Developing 

status, the Committee has sent the item back to the source or assigned it to some other entity 

outside the scope of the Committee with the responsibility of further development. The 

Committee Report will provide the source with clear indication of what is necessary to move the 

item forward for full consideration. The item will be carried in the Committee agenda in 

bulletin board fashion with contact information for the person or organization that is responsible 

for the development. Since the Committee is not required to receive testimony on developing 

items, this status should be carefully implemented so as not to weaken the standards 

development process; or

34. “Withdrawn” – these are items which will no longer be considered by the Committee and are 

indicated with a “W” after the item number in the agendaThese are items that the Committee

has found to be without merit. The committee's determination to withdraw should not be based 

on the Committee's opinion alone, but on the input received from stakeholders. The committee's 

report will contain an explanation for the withdrawal of the item. Once an item appears in 

NCWM Publication 16 as Withdrawn, the status of that item may not be amended. The item 

may be reintroduced through the regional associations for consideration as a new item.

M. Developing Items.

In the past the Committee had either carried undeveloped proposals forward as informational, or 

withdrawn them. Conference members felt that carrying undeveloped informational items on its 

agenda for years posed an unnecessary drain on NCWM resources. Alternatively, the Conference 

was also concerned that withdrawing items prematurely resulted in the Committee discarding 

valuable work that had gone into identifying and presenting the items. NCWM was also interested in 

providing a mechanism to inform parties about items that were developing in different localities or in 

the regional associations.

At the 1998 Annual Meeting, NCWM established a process for disseminating information on items 

that may have merit but are insufficiently developed for Committee action. NCWM established a 

new “Developing” designation to allow the Committee to notify the submitter that while this item 

may have merit, it has not been adequately developed for action at the national level. NCWM agreed 

that developing items should be submitted by the regional associations with a recommendation that 

they be presented as “D” items on the national agenda.

The Committee will present “D” items in list format at the end of its report and include a point of 

contact (including the name and telephone number of the submitter) so that interested parties can 

obtain additional information. No comments will be taken on a developing item unless the 

Committee agrees to receive the new information in advance of the hearing. In these cases, the 

Chairman will announce in advance that an item will be discussed in the session. The use of this “D” 

designator is seen as an item management tool, as well as a way to keep the membership informed of 

emerging items.

(Re-letter remaining sections)

Background/Discussion: 

There is inconsistency in understanding among NCWM members and regional associations of the purpose and 

impact of recommending or assigning an item status to an agenda item. The NCWM Board of Directors discussed 

the various status designations and developed additional guidance for use by NCWM standing committee members. 
BOD 2013 Final Report

BOD - 15

That guidance is now part of the NCWM Committee Handbook, has been presented to committee members at fall 

orientation sessions, and has been refined as a result of those meetings with the help of committee chairs and NIST 

technical advisors.

An example of this clarification is the distinction between “Developing” items and “Informational” items. F or 

“Developing” items, the Committee is not responsible for Developing the item and has assigned that responsibility 

to some person or organization outside of the Committee; usually the source. Items designated as “Informational” 

may also require development, but the Committee is taking responsibility for the item, either directly or through a 

subcommittee or task group appointed by the NCWM Chair that reports directly to the Committee. 

Committee members understand that items designated as “Informational” or “Developing” in NCWM Publication 

16 cannot be upgraded to “Voting” status that same year. In the course of those discussions, it has been suggested 

that an item designation of “withdrawn” by a committee following the NCWM Interim Meeting may be upgraded by 

the Committee to “Informational” or “Developing” at any time prior to adoption of the Committee’s final report at 

the NCWM Annual Meeting. T hese matters are not specifically addressed in NCWM policy and have sparked 

concern and discussion. The Board proposes including additional guidance in the Introduction section of NIST 

Handbooks 44 and 130 in an effort to improve understanding and application of item status recommendations by 

regional associates and NCWM standing committees.

NCWM committee members are told in orientation and in the NCWM Committee Handbook that they “own” an item 

right up to the point where there is a call for a vote. However, it is not standard practice to modify the status of a 

withdrawn item after that designation is established by the Committee in January. Once a committee designates an 

item as withdrawn, stakeholders may discontinue paying attention. The Board is concerned that a policy allowing 

that status to be reversed prior to adoption of the report in July may cause the Committee to be subjected to undue 

pressure. The Board proposes as part of this amendment to clarify that Withdrawn items must remain Withdrawn. 

If an item does have merit, it may be reintroduced through the regions in the fall as a new item.

Members expressed that the language should be the same in both NIST Handbooks 44 a nd 130. The proposed 

language clearly relates the current interpretation of the definitions.

At the 2013 Annual Meeting, the Board modified the proposal to avoid unintended consequences for items that are 

changed to Withdrawn at an Annual Meeting. The originally proposed version of new Section L, paragraph 4 was 

as follows:

34. “Withdrawn” – these are items which will no longer be considered by the Committee and are 

indicated with a “W” after the item number in the agendaThese are items that the Committee has 

found to be without merit. The committee's determination to withdraw should not be based on the 

Committee's opinion alone, but on the input received from stakeholders. The committee's report will 

contain an explanation for the withdrawal of the item. Once an item appears in NCWM 

Publication 16 or the Annual Meeting addendum sheets as Withdrawn, the status of that item may 

not be amended. The item may be reintroduced through the regional associations for consideration 

as a new item.

The Board removed the phrase, “or the Annual Meeting addendum sheets” from the proposal, commenting that a 

Committee decision at an Annual Meeting to change the status of an item to Withdrawn should not be a final 

decision until the Committee report is adopted. Prior to that vote, the Committee itself may change its mind or the 

voting membership may amend the item.

130 FINANCIALS

130-1 I Financial Report

NCWM operates on a f iscal year of October 1 through September 30. Budgets are set to be conservative on 

projected revenues and realistic on anticipated expenses. 
BOD 2013 Final Report

BOD - 16

Below is a graphic view of past 10 fiscal years based on year-end audit reports. The spike in expenses in 2008 

reflects the cost transition from contracted management services to hired employees and, procured office space, 

furniture, computers, etc. The graph shows significant savings in the following years of 2009 - 2011 even though 

NCWM has invested significantly in new initiatives during that time. Those initiatives include NCWM and regional 

website development, the Online Position Forum, the Professional Certification Program, and other improvements to 

services. The Board of Directors continues to monitor its ability to fully implement contingency plans based on 

potential costs compared to reserve funds. 

The following is the balance sheet as of March 31, 2013, in comparison with the same time the previous year.

I. REPORT ON THE ACTIVITIES OF THE OIML TECHNICAL COMMITTEES

This section reports on recent activities and the status of work in the OIML Technical Committees (TCs), Technical 

Subcommittees (SCs), and Project Groups (PGs) of specific interest to members of the National Conference on 

Weights and Measures (NCWM). S chedules of future activities of the TC/SC Secretariats, PG Convenors, the 

U.S. National Work Groups (USNWGs), and the International Work Groups (IWGs) and Project Groups of the TCs 

and SCs are also included.

TC 3/SC 5 Conformity Assessment (United States) 

The OIML Basic Publications B 3 Certificate System and B 10 Mutual Acceptance Arrangement (MAA) were 

recently revised to incorporate updated practices, and to provide full consistency (including terminology) between 

the two documents. At the International Committee of Legal Metrology (CIML) Meeting in Bucharest, Romania, in 

October 2012 an Amendment to B 10 was approved that allows for the voluntary use of test data from 

manufacturer’s test laboratories (MTLs) under specially supervised conditions. A Workshop is planned for the 2013 

CIML Meeting (in Vietnam) to gather experiences of the various users and other stakeholders in the MAA. The 

2nd Committee Draft (2 CD) of a new OIML document entitled The Role of Measurement Uncertainty in Conformity 

Assessment Decisions in Legal Metrology is under development by the Secretariat. Please see the MAA section in 

the National Type Evaluation Program (NTEP) Committee Report of this publication for more details on the 

activities of TC 3/SC 5. For more information on the activities of this subcommittee, please contact Dr. Charles 

Ehrlich at (301) 975-4834 or charles.ehrlich@nist.gov. 

TC 5/SC 1 Environmental Conditions (Netherlands)

The Secretariat distributed the 2 CD revision of OIML Document D 11 General requirements for measuring 

instruments - Environmental conditions, in January 2012. This is a very important document in the OIML system 

and is used by all of the OIML TCs as a general reference for technical and testing requirements on all measuring 

instruments. The United States submitted comments on the 2 CD in March 2012. Before distribution of the 2 CD, 

the United States participated in a meeting of TC 5/SC 1 to discuss the D 11 document in Utrecht, The Netherlands. 

Highlights of the discussions in Utrecht included: expanding the terminology section, updating several testing 

sections to reflect the latest International Electrotechnical Commission (IEC) reference standards, and including a 

new environmental class (“E3”) for a non-mains local source of electrical power supply. The OIML Expert Report 

E 5 Overview of the Present Status of the Standards Referred to in OIML D 11 – General Requirements for 

Electronic Measuring Instruments was recently published and updates all of the IEC references for testing 

requirements in D 11. The DD of D 11 passed its CIML preliminary ballot in December 2012. It is expected that 

this new revision of D 11 will be approved by the CIML and be published later in 2013. Please contact Mr. Ralph 

Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like further information on this project.

TC 5/SC 2 Software (Germany and BIML)

The OIML D 31 General Requirements for Software-controlled Measuring Instruments has been published and will 

serve as guidance for software requirements in International Recommendations by OIML TCs. The United States 

participated in the technical work on this document and submitted votes and comments on several drafts of the 

document. A new project on software verification was approved by CIML, and the United States is waiting for the 

first draft of this document. Please contact Dr. Ambler Thompson at (301) 975-2333 or ambler@nist.gov if you 

would like to discuss OIML software efforts.

TC 6 Prepackaged Products (South Africa) 

After an online CIML vote was conducted, it was decided that the TC 6 project to develop an OIML International 

Quantity Mark (IQ Mark) would be terminated. The United States had already voted in favor of terminating this 
BOD 2013 Final Report

Appendix A – Report on the Activities of OIML and Regional Legal Metrology Organizations

BOD - A4 

project on the grounds that the effort to manage and certify quality control systems would have added unnecessary 

extra costs, with no value added, to all participating suppliers. At the same time, another CIML vote (same 

deadline) was conducted on a proposal for a new TC 6 project Guidance for defining the system requirements for a 

certification system for prepackages. The United States voted against this proposal on the grounds that even such an 

OIML Guidance Document could be construed as endorsing an OIML IQ Mark program. The results of the CIML 

vote on this proposal, and the best way forward are still being decided. 

A meeting of TC 6 was held in Tokyo, Japan, in October 2012. Besides the IQ Mark project, two other important 

projects were heavily discussed: a revision of OIML Recommendation (R) 87 Quantity of Product in Prepackages 

(the OIML equivalent to NIST Handbook 133, Checking the Net Contents of Packaged Goods) and a revision of 

OIML R 79 Labeling Requirements for Prepackaged Products. The NIST Statistical Engineering Division (SED) 

has been participating in a small ad-hoc work group to improve the statistics in R 87. A 1st Committee Draft of R 87 

has been developed and circulated for comment by the Secretariat. Also, the Secretariat has developed and 

circulated for comment a 3rd Committee Draft of R 79. The comment period for both of these CDs ended in March 

2013. Both drafts contain proposed revisions that NIST OWM believes are unnecessarily complex, and, therefore, 

subject to easy misinterpretation, and another that appeared to go beyond the scope of package labeling 

requirements. After consulting with the Chairman of the NCWM Packaging and Labeling Subcommittee about the 

proposed revisions to both R 87 and R 79, the United States voted “no” on R 79 (votes are not taken on 

1st Committee Drafts, so only comments were submitted on R 87). The main reason for opposing both drafts is that 

they include proposed definitions for prepackage, packaging material, and product that are likely to result in 

confusion for consumers and packers alike.

For more information on the activities of this subcommittee, and to participate in the U.S. review of these CDs, 

please contact Mr. Ken Butcher at (301) 975-4859 or kbutcher@nist.gov. 

TC 8 Measurement of Quantities of Fluids (Japan)

The CIML has approved projects to revise the following TC 8 documents: R 63 Petroleum Measurement Tables 

(1994) and R 119 Pipe Provers for Testing of Measuring Systems for Liquids Other Than Water (1996). Both of 

these documents are important for other OIML recommendations involving liquid measurement. P lease contact 

Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like copies of the documents or to 

participate in any of these projects.

TC 8/SC 1 Static Volume and Mass Measurement (Germany)

The United States chairs the Project Group that is drafting new sections of OIML R 71, Fixed Storage Tanks and 

R 85, Automatic Level Gages for Measuring the Level of Liquid in Fixed Storage Tanks to add specific requirements 

for specialized tanks. OIML R 80-2, Road and Rail Tankers, Test Methods, is being developed by Germany. Please 

contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like to receive copies of the 

documents, or to participate in any of these projects.

TC 8/SC 3 Dynamic Volume and Mass Measurement for Liquids Other Than Water (United States 

and Germany) 

Subcommittee work is continuing on the development of OIML R 117-2, Dynamic Measuring Systems for Liquids 

Other Than Water, Part 2, Test Methods, and R 117-3, Test Report Format. New annexes for measuring systems 

for foaming potable liquids, for pipelines, and for aircraft refueling are being developed. The Project Group for the 

development of R 117 also continues to hold international web-meetings to accelerate the work on this high priority 

document.

A meeting of the full TC 8/SC 3 subcommittee was hosted by the European Committee of Manufacturers of 

Petroleum Measuring Systems (CECOD) and the Syndicat de la Mesure at their Paris headquarters in 

November 2012. The subcommittee meeting was attended by 31 participants, including official representatives 

from 15 countries. Additionally, several representatives of major manufacturers of these systems and liaison 

organizations actively participated in the meeting. These technical experts provided a depth of experience and 

technical expertise that proved highly valuable during the meeting. T he 2 CD of R 117-2 is planned to be

distributed in April 2013, and a meeting of the R 117 Project Group will be held October 1 - 3, 2013, in London, 

England. If you have any questions or would like to participate in the next phases of this project, please contact 

Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov. 

TC 8/SC 5 Water Meters (United Kingdom) 

OIML, the International Standardization Organization (ISO), and the European Committee for Standardization 

(CEN) are working together to harmonize requirements for water meters using OIML R 49, Water Meters Intended 

for the Metering of Cold Potable Water and Hot Water Parts 1, 2, and 3 as the base document. The 3 CD of the 

harmonized document was distributed in June of 2012. The United States submitted comments on the 3 CD in 

September 2012 and participated in a meeting of the Joint Working Group of these three organizations in London in 

October 2012. The American Water Works Association Committee on Water Meters is assisting in these efforts. 

The DR of R 49 passed its CIML preliminary ballot in May 2013, and R 49 is expected to receive final approval by 

the CIML in October 2013. Please contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you 

would like copies of documents or to participate in this project.

TC 8/SC 6 Measurement of Cryogenic Liquids (United States)

The Secretariat for R 81, Dynamic Measuring Devices and Systems for Cryogenic Liquids is working to complete 

project 1 to update: (1) electronic tests in accordance with the latest edition of OIML D 11 and/or the latest IEC and 

ISO standards; (2) technical requirements to include new developments in hydrogen measurements; and (3) current 

recommendations for density equations. OIML R 81 (1998) will be reformatted into two distinct parts in the format 

that is recommended for OIML Recommendations. The Secretariat asked members of TC 8/SC 6 and the USNWG 

to review and formally comment on the first committee draft of revised R 81, Part 1: Metrological and technical 

requirements and Part 2: Metrological controls and performance tests in May 2013. To obtain more information or 

to participate in this project, please contact Ms. Juana Williams at (301) 975-3989 or juana.williams@nist.gov. 

TC 8/SC 7 Gas Metering (Netherlands)

OIML R 137-1 and R 137-2, Gas Meters; Part 1: Metrological and Technical Requirements and Part 2: 

Metrological Controls and Performance Tests were published in May 2012. Extensive United States comments on 

the 1 CD, the 2 CD, and the DR were developed in cooperation with the measurement committees of the American 

Gas Association. The OIML R 137 document is especially important to the U.S. interests because the American 

National Standards Institute (ANSI) B 109 committee on gas measurement is using the published R 137 to create a 

new performance-based standard for gas meters in the United States. Meetings of the working group that is 

developing this new standard ANSI B 109.zero were held in Charleston, South Carolina, in January 2013 and in

Plano, Texas, in March 2013. Please contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you 

would like to participate in these efforts of if you would like to obtain a copy of any of these gas measurement 

documents.

The Project Group that is developing OIML R 139, Compressed gaseous fuel measuring systems for vehicles,

distributed the 1 CD of the revised R 139 in May 2012. This standard is important to U.S. stakeholders, especially 

in the effort to maximize harmonization between domestic and international legal metrology requirements used for 

the delivery of alternative fuels such as hydrogen gas and compressed natural gas (CNG). T he United States 

submitted comments on the 1 CD in August 2012, and participated in a Project Group meeting in November 2012 in 

Delft, The Netherlands. The United States voted “yes” with comments on the 2 CD of R 139 in April 2013. To 

obtain more information or to participate in this project, please contact Ms. Juana Williams at (301) 975-3989 

or juana.williams@nist.gov. 

TC 9 Instruments for Measuring Mass (United States)

The CIML approved a work item to revise OIML R 60:2000, Metrological Regulation for Load Cells. This revision 

is planned to cover everything from the basic principles of R 60 (e.g., tolerances and accuracy classes) to exploring 

the addition of new requirements. The United States distributed a 1st Committee Draft of R 60 Parts 1 and 2 

(Metrological and technical requirements and Metrological controls and performance tests) to TC 9 members in 

August 2012. Comments on the 1 CD were due in November 2012 and were incorporated into a 2 CD. The 2 CD

was circulated in June 2013. For more information on these efforts, please contact Mr. John Barton at (301) 975-

4002 or john.barton@nist.gov. 

TC 9/SC 2 Automatic Weighing Instruments (United Kingdom)

The DR of OIML R 106, Part 1, Automatic Rail Weighbridges, was approved by a d irect CIML online vote in 

April 2011, and R 106-1 was published in February 2012. The DR of R 106-2 was approved by the CIML in May 

2012 and is awaiting publication by the BIML. To receive copies of these documents or to obtain more information 

on the work of this subcommittee, please contact Mr. John Barton at (301) 975-4002 or john.barton@nist.gov. 

The Secretariat is in the process of revising OIML R 50, Continuous Totalizing Automatic Weighing Instruments

(Belt Weighers). The United States submitted comments on the 5 CD, Parts 1 and 2, of this Recommendation in 

October 2012. The Secretariat is now developing a DR of R 50-1 and R 50-2 for submission to the BIML as a 

CIML preliminary ballot. Comments have been returned on Part 3 of this Recommendation, and the Secretariat 

distributed the 2 CD of Part 3 in July 2013. For more information on this effort, please contact Mr. John Barton at 

(301) 975-4002 or john.barton@nist.gov. 

TC 17/SC 1 Humidity (China and United States)

The Co Secretariats are working with a small International Project Group to revise OIML R 59, Moisture Meters for 

Cereal Grains and Oilseeds. All drafts have been distributed to the USNWG, which for the most part is a subset of 

the National Type Evaluation Program Grain Analyzer Sector. A preliminary 6 CD was developed based on 

international comments received on the 5 CD, and a meeting of TC 17/SC 1 was held in Orlando, Florida, to address 

those comments. Per discussions during that meeting, Germany submitted suggestions for additional software 

requirements that were included in the 6 CD. The 6 CD was distributed in March 2013 with comments returned in

June 2013. Meetings of TC 17/SC 1 and TC 17/SC 8 will be held at NIST in Gaithersburg, July 23 - 25, 2013. 

Please contact Ms. G. Diane Lee at (301) 975-4405 or diane.lee@nist.gov if you would like to participate in this 

IWG.

TC 17/SC 8 Quality Analysis of Agricultural Products (Australia)

This subcommittee was formed to study the issues and write a working draft document Measuring Instruments for 

Protein Determination in Grains. Australia is the Secretariat. At a TC 17/SC 8 meeting hosted by NIST, the 

subcommittee discussed comments concerning the maximum permissible errors and harmonization of the 

TC 17/SC 8 Recommendation for protein with the TC 17/SC 1 Recommendation for moisture. International 

comments on the 2 CD were received and compiled. These comments were discussed at a meeting of TC 17/SC 8 in 

Orlando, Florida. The Secretariat completed the 3 CD based on the meeting discussion in Orlando. The United 

States submitted comments on the 3 CD in October 2012. Meetings of TC 17/SC 1 and TC 17/SC 8 was held at 

NIST in Gaithersburg, July 23 - 25, 2013. Please contact Ms. G. Diane Lee at (301) 975-4405 

or diane.lee@nist.gov, if you would like to participate in this IWG.

OIML Mutual Acceptance Arrangement (MAA)

MAA and its implementation, please contact Dr. Charles Ehrlich at (301) 975-4834 or email charles.ehrlich@nist.gov. 

II. REPORT ON THE 47TH CIML MEETING IN BUCHAREST, ROMANIA IN 

OCTOBER 2012 

Mr. Peter Mason, CIML member from the United Kingdom and President of the CIML, opened the meeting and 

gave the President’s Report. 

Mr. Stephen Patoray, who has been serving as BIML Director since January 2011, provided several reports on 

financial and administrative matters at the BIML, including improvements that have been implemented since his 

arrival at the BIML. After consideration of an external auditor’s review of the 2011 OIML accounts, the CIML 

approved the 2011 accounts, and instructed its President to present them to the 14th OIML Conference.
BOD 2013 Final Report

Appendix A – Report on the Activities of OIML and Regional Legal Metrology Organizations

BOD - A7 

Mr. Patoray announced that there are seven new OIML Corresponding Members (all from Africa): Gambia, Liberia,

Malawi, Mauritania, Namibia, Nigeria, and Sierra Leone. He also announced that Colombia would soon become an 

OIML Member State. 

Dr. Grahame Harvey (Australia), currently serving as CIML 1st Vice President, announced that he was stepping 

down as the CIML Member from Australia due to financial considerations in Australia. Because of this, he also 

announced that he would not be running for reelection as CIML 1st Vice President. Discussions during the course of 

the CIML meeting eventually led to the appointment of the CIML 2nd Vice President (Roman Schwartz of PTB in 

Germany) to the position of 1st Vice President, with the decision to leave the position of 2nd Vice President unfilled

until a new election could be held at the 2013 CIML meeting.

It was decided that the OIML Translation Center already has enough money to cover paying for a backlog of 

English to French translations of OIML publications, and that in the future such translations should be paid out of a 

regular budget line item. No formal action was taken on this item.

The CIML adopted 25 Resolutions in Bucharest, Romania. The most noteworthy resolutions included:

• the proposed 2013-2016 budget was agreed to be forwarded to the OIML Conference (including a line 

item for indirect support to developing countries, in areas such as training videos);

• the draft revision of the OIML Financial regulations were adopted (with minor amendments);

• Corresponding Members may now participate as Observing Members on OIML Technical Committees, 

Subcommittees, and Project Groups (without having to pay a fee);

• the revision of OIML B 6 Directives for the Technical Work was approved (subject to any necessary 

editorial changes that the United States submitted);

• the extension of the OIML Mutual Acceptance Arrangement to include test data from manufacturer’s test 

labs (MTLs) on a voluntary basis was approved; and 

• the NIST wording pertaining to a Resolution on the New SI was accepted. 

The CIML approved the following Draft Publications in Bucharest, Romania: 

• Revision of OIML D 1 Considerations for a law on metrology, 

• Revision of OIML R 46 Electrical energy meters - Part 1: Metrological and technical requirements and 

Part 2: Metrological controls and performance tests, 

• Revision of OIML R 106-2 Automatic rail weighbridges - Part 2: Test report format. 

The CIML granted a special approval to OIML R 126, Evidential breath analyzers. Previously, in the preliminary 

ballot stage of R 126, the DR received five negative votes, some of which contained objections requiring substantial 

changes to the draft. Because the Secretariat of TC 17/SC 7 did not see any possibility to prepare a further draft that 

would remove the objections expressed in the preliminary ballot and because it was agreed that the revised text is a 

substantial improvement over the old version of OIML R 126 – the CIML decided to approve R 126 and then 

immediately start a revision process on the Recommendation.

III. REPORT ON THE 14TH OIML CONFERENCE IN BUCHAREST, ROMANIA, IN 

OCTOBER 2012 

The OIML Conference adopted 16 Resolutions in Bucharest, many of which had to do with formalizing the adoption 

of Resolutions from the CIML Meeting on budgetary, policy, and administrative matters.
BOD 2013 Final Report

Appendix A – Report on the Activities of OIML and Regional Legal Metrology Organizations

BOD - A8 

The audited accounts for 2008 - 2011 were approved, and it was decided that the budget surpluses (net results) from

CIML at a future date.

V. REGIONAL LEGAL METROLOGY ORGANIZATIONS

Meeting of the Inter-American Metrology System (SIM) General Assembly and the SIM Legal Metrology 

Work Group (LMWG)

The SIM General Assembly (GA) was held in San Jose, Costa Rica, in November 2012. Mr. Jose Dajes Castro, 

from INDECOPI in Lima, Peru, serves as the SIM President. Mr. Marcos Senna at mjsenna@inmetro.gov.br, of 

INMETRO in Brazil, recently announced his resignation as the Chairman of the SIM LMWG. A new Chairman is

being sought. The organization is working to build capacity in legal metrology for SIM member countries. Please 

contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov for more information on SIM.

Asia-Pacific Legal Metrology Forum (APLMF)

The 19th Meeting of APLMF was held November 5-9, 2012, in Cebu, The Philippines. Sixteen APLMF Member 

Economies participated in this meeting. The People’s Republic of China holds the Presidency and Secretariat of 

APLMF. Mr. Changcheng, APLMF President and Vice Minister of AQSIQ, chaired the meeting. APLMF activities 

are facilitated through its seven work groups. The most active is the work group on Training Coordination chaired 

by Australia.

The main objectives of APLMF are to coordinate regional training courses in legal metrology and to provide a 

forum for exchange of information among legal metrology authorities. The APLMF Secretariat spent a considerable 

amount of time, with the assistance of the United States, developing a proposal to obtain support from the AsiaPacific Economic Cooperation (APEC) – Trade and Investment Liberalization and Facilitation funding in order to 

support the delivery of the training in 2012. Changes in APEC priorities are making it more difficult to achieve 

funding. While feedback from the previously-held training courses has been positive, it is becoming clear that in 

order to continue to receive funding for the training, APLMF needs to do a more thorough job of assessing and 

documenting the impact of the training courses on the economies that receive the training.

Discussions in Cebu included a review of the events and training courses held since the last APLMF meeting; these 

included:

• An APLMF-APMP Joint Symposium on “Metrology for Economic and Social Sustainability” (Beijing);

• An APLMF Training Course on “Traceability in Rice Moisture Measurement” (Indonesia, ‘self-funded’);

• A Training Course on “Verification of Non-automatic Weighing Instruments (Papua New Guinea); 

• A Workshop on Technical Regulation and Harmonization of Bulk Fuel Trade Transactions in the APEC 

Region, Part 1 – “Improving the Custody Transfer of Liquid Fuel in the Asia-Pacific Region” (Singapore) 

(Ralph Richter of the NIST Office of Weights and Measures was the trainer); and

• A Workshop on Technical Regulation and Harmonization of Bulk Fuel Trade Transactions in the APEC 

Region, Part 2 – “Verification of bulk fuel using volumetric methods” (Thailand).

The United States was represented at the meeting in Cebu by Dr. Charles Ehrlich, who serves as Chairman of the 

APLMF work group on Mutual Recognition Arrangements. Dr. Ehrlich gave an extensive report and with updates 

on the OIML MAA and presented the United States Country Report. The 2013 APLMF meeting will be held in 

Yogyakarta, Indonesia, November 5 - 8, 2013.

AMC Draft Meeting Minutes

July 16, 2013 

Louisville, KY 

Call to Order

Chairman Robert Murnane called the meeting to order at 5:00 p.m.

Meeting Minutes

A copy of the 2013 Interim Meeting Minutes was distributed. These minutes were reviewed and a motion was made 

by Mr. Flocken and seconded by Mr. Johnson to approve the minutes as written. With no further discussion, the 

minutes were approved.

Financial Condition

A copy of the financial report was distributed; Chairman Murnane reported that the AMC fund has a balance of 

$26,602.49. Ms. Jucoch questioned what the plans are for the current balance. Chairman Murnane explained the 

process for scholarships, and how the money is approved through the online form for requests for training. There 

were also questions regarding where the money comes from to support the balance. Chairman Murnane reports that 

$15 from each membership is deposited in the AMC account.

Mr. Flocken stated that the annual dues are expected to increase the balance. Mr. Lewis reports one of the benefits 

of being a member is you get discount on NTEP certification fees. Chairman Murnane reported that there are 

discounts for testing as well.

Mr. Johnson reports there are currently 2156 members in the Conference; 803 associate members depending on the 

issue.

The financial report was reviewed and a motion was made by Mr. Johnson and seconded by Mr. Flocken to approve 

the financial report as written.

Board of Directors Report

Mr. Johnson, AMC representative on NCWM Board of Directors, gave a report regarding Board activities:

Mr. Johnson reports that the Conference has lost some very experienced weights and measures officials.

Terrence McBride had to resign from the BOD due to budget/travel issues with his program, and Clark Cooney of 

Oregon retired. 

The SWMA Meeting will be in Charleston, West Virginia, October 7 - 9, 2013, and the Measuring Sector Meeting 

will meet after the SWMA Meeting. 

AMC – Nothing new other than they are waiting for a response to a request for any kind of assistance on the new 

tool kit – whether funds or other support. 

Several states and NIST are requesting help with travel expenses for training. The states and NIST can provide the 

training, but lack of travel funds is limiting attendance at these important training programs. 

NIST – Package Inspection Training, help is needed in funding the purchase of materials (groceries) for these 

classes.

NIST/WMD – Ms. Carol Hockert reported that Mr. Marc Butler resigned. She is looking to fill this position as soon 

as possible. 

Work GROUP Updates – The Taximeters Work Group is looking for a statement from NIST regarding the use of 

alternative devices. A newsletter article may help address what tools the states have when looking at devices that 

are not covered in NIST Handbook 44 or NTEB approved.

NCWM Treasurers Report – The NCWM is in good financial shape. 

Activity Reports – Current membership is 2156. 

Annual and Interim Meetings – 2015 Planning for the 100th meeting is in process – Need AMC input. Chairmen

Toolkit Work Group – NCWM Chair, Mr. Steve Benjamin met with the NEWMA and CWMA. First priorities for 

these groups are for a video and templates (CWMA). Mr. Benjamin will meet with the SWMA and WWMA this 

week. A task group will meet Sunday afternoon.

NTEP Staffing – NCWM advertised a new position for additional NTEP personnel. There is a lot of interest and 

candidates.

Professional Development Committee (PDC) Report

Mr. Steve Grabski mentioned that getting the trainers out traveling will be a big help. Chairman Murane mentions 

that he appreciates the work that the PDC has completed. Pretty much everyone present at the Conference for 

business has a course that pertains to him or her. 

Laws and Regulations (L&R) Committee Report

Mr. Grabski will be move to the L&R Committee from PDC; No updates for the L&R Committee. 

AMC Fund Disbursement Report

Chairmen Murnane reports the Washington request was paid, and the California request is still pending. 

California’s training will take place in August. 

Filling Vacant Positions

Mr. Paul Lewis agreed to fill the Associate Chair. 

Mr. Bill Callaway agreed to fill Vice Chair. 

Mr. David Calix agreed to fill Secretary Treasure. 

Associate Committee Member - Darrel Flocken – will stay on as a committee member.

Associate Committee Member - Chairman Murnane – will stay on as a committee member. 

Old Business

Mr. Gurney reports there is a request for training for the Northern Mariana Islands a U.S. territory; they are looking 

for training on package inspections. Mr. Don Onwiler and NIST put their heads together on who could do this 

training and decided on Mr. Gurney. T he Northern Mariana Islands will be putting a request together for 

approximately $4300; they want the AMC to think it over.

Chairmen Munane asked, “Does NIST have an online course for the training? Are the Northern Mariana Islands 

members of the Conference? Could the training be completed through a webinar or WebEx?” Chairmen Murnane 
BOD 2013 Final Report

Appendix B – AMC Agenda and Draft Minutes

BOD - B4 

asks that they check into online training and then apply online. Mr. Gurney stated originally there were going to be 

approximately 25 people needing training, and then there were some issues with getting all the folks to the training. 

Mr. Flocken stated that the more information that can be provided in the application the better and it can be look at 

as a cost vs. value. Mr. Lewis states that they should make sure they request enough funds; AMC will not approve 

extra funds. Chairmen Murnane ask that Mr. Gurney get the information regarding WebEx, Webinar, NIST and 

online training, put in the application and the Committee will vote on it. 

Mr. Oppermann believes that it is a worthwhile request. Chairmen Murnane asked if NIST is available for the 

training. 

Mr. Onwiler reports that the Northern Mariana Islands does not have a NCWM membership at this time. Mr. 

Onwiler stated that NCWM does have a WebEx account that he uses to host meetings for NCWM groups. Chairmen 

Murnane reported that there may be an issue if they are not members, and Mr. Lewis stated not all the inspectors that 

are trained with AMC funds are members. 

Mr. Gurney will get the information for the requested training and put in a request for funds when all details become 

available.

New Business

Chairman Murnane stated that Ms. Julie Quinn (Minnesota) is requesting money to send people on travel. Mr. 

Floken stated that we will pay for travel for trainers, but not for travel for people to get training. 

Chairmen Murnane states that it’s difficult to control. You don’t know what the benefits are and what we will get 

out of it. We will pay for trainers to travel and facilities but not for trainees to get training. 

Chairmen Murnane stated we will buy the items for packing checking and tools. 

Chairmen Murnane asked, “Is there something that the AMC wants to do for the NCWM’s 100th Meeting?” Mr. 

Lewis asked, “Do we want to make a pin or a paper weight?” 

Mr. Flocken stated that the SMA was looking into sponsoring a lunch but we cannot do that. The Conference will 

not accept sponsorship.

Mr. Flocken stated he would rather spend the money on training as it’s designed. 

Mr. Onwiler reported that the Conference will not accept any sponsorship, the policy is very clear, if a group wants 

to go off and do something on their own, NCWM cannot endorse it and that activity would violate a gentlemen’s 

agreement against hospitality suites. The work group is asking to suspend the rules for one event. The decision has 

not been made. 

Chairmen Murnane stated he would like for the policy to stand, if the news media were to get ahold of it and spin it 

the wrong way it would look very bad for the Conference. 

Mr. Onwiler stated NIST put together the very first handbook standards adopted by NCWM as a gift to the attendees 

of NCWM’s 100-Year Anniversary Event. 

Is there a difference between providing food and beverage vs. providing a gift? Mr. Onwiler does not know if that 

would be allowed, but that’s still sponsorship, and it’s a board decision. Mr. Onwiler encourages that we voice 

comments to the Board regarding sponsorship.

Mr. Lewis states members are welcome to set up their own booth and give away items. Mr. Onwiler stated that 

NCWM is not sponsoring it. 

Mr. Onwiler wants the 100th to be a success.
BOD 2013 Final Report

Appendix B – AMC Agenda and Draft Minutes

BOD - B5 

Chairmen Murnane does not want to relax the rules, and we want to stay above reproach at all times. We don’t want 

companies to have hospitality suites serving shrimp cocktails all night that’s negative for the Conference. 

Mr. Flocken stated that he supports what Chairmen Murnane says. Mr. Flocken stated giving away a gift or pin is 

not money well spent. We need to save the money for training opportunities. 

Ms. Hemida asked, “Can we call suppliers and put on training for the Conference?” Chairmen Murnane stated that 

the training would be more beneficial at the regional level. Most of the folks attending the National meeting are not 

the ones needing training. 

Ms. Hemida asks why not come up with something about the history of weights and measures past 100 years of 

events. How did we get to where we are now – a video or a DVD of five to seven minutes of the history? 

Chairmen Murnane asked how about weights and measure history as a video, understanding the history of weights 

and measures. 

Mr. Oppermann reported that Mr. Onwiler told him the estimated cost is $1000/min. We would not need a very 

lengthy video. 

Ms. Juroch asked if the Smithsonian has anything on the history of scales. 

You have to touch everything, scales, gas pumps, all parts of weights and measures. 

Chairmen Murnane and the group liked the DVD idea; Ms. Hemida will get with Mr. Onwiler and let us know on 

the feedback. 

Adjournment

Mr. Oppermann said thank you Chairmen Murnane for his effort and his contribution. 

Mr. Lewis moved to adjourn the meeting, a motion was made, and the meeting was adjourned at 5:58 p.m.

I. REPORT ON THE ACTIVITIES OF THE OIML TECHNICAL COMMITTEES

This section reports on recent activities and the status of work in the OIML Technical Committees (TCs), Technical 

Subcommittees (SCs), and Project Groups (PGs) of specific interest to members of the National Conference on 

Weights and Measures (NCWM). S chedules of future activities of the TC/SC Secretariats, PG Convenors, the 

U.S. National Work Groups (USNWGs), and the International Work Groups (IWGs) and Project Groups of the TCs 

and SCs are also included.

TC 3/SC 5 Conformity Assessment (United States) 

The OIML Basic Publications B 3 Certificate System and B 10 Mutual Acceptance Arrangement (MAA) were 

recently revised to incorporate updated practices, and to provide full consistency (including terminology) between 

the two documents. At the International Committee of Legal Metrology (CIML) Meeting in Bucharest, Romania, in 

October 2012 an Amendment to B 10 was approved that allows for the voluntary use of test data from 

manufacturer’s test laboratories (MTLs) under specially supervised conditions. A Workshop is planned for the 2013 

CIML Meeting (in Vietnam) to gather experiences of the various users and other stakeholders in the MAA. The 

2nd Committee Draft (2 CD) of a new OIML document entitled The Role of Measurement Uncertainty in Conformity 

Assessment Decisions in Legal Metrology is under development by the Secretariat. Please see the MAA section in 

the National Type Evaluation Program (NTEP) Committee Report of this publication for more details on the 

activities of TC 3/SC 5. For more information on the activities of this subcommittee, please contact Dr. Charles 

Ehrlich at (301) 975-4834 or charles.ehrlich@nist.gov. 

TC 5/SC 1 Environmental Conditions (Netherlands)

The Secretariat distributed the 2 CD revision of OIML Document D 11 General requirements for measuring 

instruments - Environmental conditions, in January 2012. This is a very important document in the OIML system 

and is used by all of the OIML TCs as a general reference for technical and testing requirements on all measuring 

instruments. The United States submitted comments on the 2 CD in March 2012. Before distribution of the 2 CD, 

the United States participated in a meeting of TC 5/SC 1 to discuss the D 11 document in Utrecht, The Netherlands. 

Highlights of the discussions in Utrecht included: expanding the terminology section, updating several testing 

sections to reflect the latest International Electrotechnical Commission (IEC) reference standards, and including a 

new environmental class (“E3”) for a non-mains local source of electrical power supply. The OIML Expert Report 

E 5 Overview of the Present Status of the Standards Referred to in OIML D 11 – General Requirements for 

Electronic Measuring Instruments was recently published and updates all of the IEC references for testing 

requirements in D 11. The DD of D 11 passed its CIML preliminary ballot in December 2012. It is expected that 

this new revision of D 11 will be approved by the CIML and be published later in 2013. Please contact Mr. Ralph 

Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like further information on this project.

TC 5/SC 2 Software (Germany and BIML)

The OIML D 31 General Requirements for Software-controlled Measuring Instruments has been published and will 

serve as guidance for software requirements in International Recommendations by OIML TCs. The United States 

participated in the technical work on this document and submitted votes and comments on several drafts of the 

document. A new project on software verification was approved by CIML, and the United States is waiting for the 

first draft of this document. Please contact Dr. Ambler Thompson at (301) 975-2333 or ambler@nist.gov if you 

would like to discuss OIML software efforts.

TC 6 Prepackaged Products (South Africa) 

After an online CIML vote was conducted, it was decided that the TC 6 project to develop an OIML International 

Quantity Mark (IQ Mark) would be terminated. The United States had already voted in favor of terminating this 
BOD 2013 Final Report

Appendix A – Report on the Activities of OIML and Regional Legal Metrology Organizations

BOD - A4 

project on the grounds that the effort to manage and certify quality control systems would have added unnecessary 

extra costs, with no value added, to all participating suppliers. At the same time, another CIML vote (same 

deadline) was conducted on a proposal for a new TC 6 project Guidance for defining the system requirements for a 

certification system for prepackages. The United States voted against this proposal on the grounds that even such an 

OIML Guidance Document could be construed as endorsing an OIML IQ Mark program. The results of the CIML 

vote on this proposal, and the best way forward are still being decided. 

A meeting of TC 6 was held in Tokyo, Japan, in October 2012. Besides the IQ Mark project, two other important 

projects were heavily discussed: a revision of OIML Recommendation (R) 87 Quantity of Product in Prepackages 

(the OIML equivalent to NIST Handbook 133, Checking the Net Contents of Packaged Goods) and a revision of 

OIML R 79 Labeling Requirements for Prepackaged Products. The NIST Statistical Engineering Division (SED) 

has been participating in a small ad-hoc work group to improve the statistics in R 87. A 1st Committee Draft of R 87 

has been developed and circulated for comment by the Secretariat. Also, the Secretariat has developed and 

circulated for comment a 3rd Committee Draft of R 79. The comment period for both of these CDs ended in March 

2013. Both drafts contain proposed revisions that NIST OWM believes are unnecessarily complex, and, therefore, 

subject to easy misinterpretation, and another that appeared to go beyond the scope of package labeling 

requirements. After consulting with the Chairman of the NCWM Packaging and Labeling Subcommittee about the 

proposed revisions to both R 87 and R 79, the United States voted “no” on R 79 (votes are not taken on 

1st Committee Drafts, so only comments were submitted on R 87). The main reason for opposing both drafts is that 

they include proposed definitions for prepackage, packaging material, and product that are likely to result in 

confusion for consumers and packers alike.

For more information on the activities of this subcommittee, and to participate in the U.S. review of these CDs, 

please contact Mr. Ken Butcher at (301) 975-4859 or kbutcher@nist.gov. 

TC 8 Measurement of Quantities of Fluids (Japan)

The CIML has approved projects to revise the following TC 8 documents: R 63 Petroleum Measurement Tables 

(1994) and R 119 Pipe Provers for Testing of Measuring Systems for Liquids Other Than Water (1996). Both of 

these documents are important for other OIML recommendations involving liquid measurement. P lease contact 

Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like copies of the documents or to 

participate in any of these projects.

TC 8/SC 1 Static Volume and Mass Measurement (Germany)

The United States chairs the Project Group that is drafting new sections of OIML R 71, Fixed Storage Tanks and 

R 85, Automatic Level Gages for Measuring the Level of Liquid in Fixed Storage Tanks to add specific requirements 

for specialized tanks. OIML R 80-2, Road and Rail Tankers, Test Methods, is being developed by Germany. Please 

contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you would like to receive copies of the 

documents, or to participate in any of these projects.

TC 8/SC 3 Dynamic Volume and Mass Measurement for Liquids Other Than Water (United States 

and Germany) 

Subcommittee work is continuing on the development of OIML R 117-2, Dynamic Measuring Systems for Liquids 

Other Than Water, Part 2, Test Methods, and R 117-3, Test Report Format. New annexes for measuring systems 

for foaming potable liquids, for pipelines, and for aircraft refueling are being developed. The Project Group for the 

development of R 117 also continues to hold international web-meetings to accelerate the work on this high priority 

document.

A meeting of the full TC 8/SC 3 subcommittee was hosted by the European Committee of Manufacturers of 

Petroleum Measuring Systems (CECOD) and the Syndicat de la Mesure at their Paris headquarters in 

November 2012. The subcommittee meeting was attended by 31 participants, including official representatives 

from 15 countries. Additionally, several representatives of major manufacturers of these systems and liaison 

organizations actively participated in the meeting. These technical experts provided a depth of experience and 

technical expertise that proved highly valuable during the meeting. T he 2 CD of R 117-2 is planned to be

distributed in April 2013, and a meeting of the R 117 Project Group will be held October 1 - 3, 2013, in London, 

England. If you have any questions or would like to participate in the next phases of this project, please contact 

Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov. 

TC 8/SC 5 Water Meters (United Kingdom) 

OIML, the International Standardization Organization (ISO), and the European Committee for Standardization 

(CEN) are working together to harmonize requirements for water meters using OIML R 49, Water Meters Intended 

for the Metering of Cold Potable Water and Hot Water Parts 1, 2, and 3 as the base document. The 3 CD of the 

harmonized document was distributed in June of 2012. The United States submitted comments on the 3 CD in 

September 2012 and participated in a meeting of the Joint Working Group of these three organizations in London in 

October 2012. The American Water Works Association Committee on Water Meters is assisting in these efforts. 

The DR of R 49 passed its CIML preliminary ballot in May 2013, and R 49 is expected to receive final approval by 

the CIML in October 2013. Please contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you 

would like copies of documents or to participate in this project.

TC 8/SC 6 Measurement of Cryogenic Liquids (United States)

The Secretariat for R 81, Dynamic Measuring Devices and Systems for Cryogenic Liquids is working to complete 

project 1 to update: (1) electronic tests in accordance with the latest edition of OIML D 11 and/or the latest IEC and 

ISO standards; (2) technical requirements to include new developments in hydrogen measurements; and (3) current 

recommendations for density equations. OIML R 81 (1998) will be reformatted into two distinct parts in the format 

that is recommended for OIML Recommendations. The Secretariat asked members of TC 8/SC 6 and the USNWG 

to review and formally comment on the first committee draft of revised R 81, Part 1: Metrological and technical 

requirements and Part 2: Metrological controls and performance tests in May 2013. To obtain more information or 

to participate in this project, please contact Ms. Juana Williams at (301) 975-3989 or juana.williams@nist.gov. 

TC 8/SC 7 Gas Metering (Netherlands)

OIML R 137-1 and R 137-2, Gas Meters; Part 1: Metrological and Technical Requirements and Part 2: 

Metrological Controls and Performance Tests were published in May 2012. Extensive United States comments on 

the 1 CD, the 2 CD, and the DR were developed in cooperation with the measurement committees of the American 

Gas Association. The OIML R 137 document is especially important to the U.S. interests because the American 

National Standards Institute (ANSI) B 109 committee on gas measurement is using the published R 137 to create a 

new performance-based standard for gas meters in the United States. Meetings of the working group that is 

developing this new standard ANSI B 109.zero were held in Charleston, South Carolina, in January 2013 and in

Plano, Texas, in March 2013. Please contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov, if you 

would like to participate in these efforts of if you would like to obtain a copy of any of these gas measurement 

documents.

The Project Group that is developing OIML R 139, Compressed gaseous fuel measuring systems for vehicles,

distributed the 1 CD of the revised R 139 in May 2012. This standard is important to U.S. stakeholders, especially 

in the effort to maximize harmonization between domestic and international legal metrology requirements used for 

the delivery of alternative fuels such as hydrogen gas and compressed natural gas (CNG). T he United States 

submitted comments on the 1 CD in August 2012, and participated in a Project Group meeting in November 2012 in 

Delft, The Netherlands. The United States voted “yes” with comments on the 2 CD of R 139 in April 2013. To 

obtain more information or to participate in this project, please contact Ms. Juana Williams at (301) 975-3989 

or juana.williams@nist.gov. 

TC 9 Instruments for Measuring Mass (United States)

The CIML approved a work item to revise OIML R 60:2000, Metrological Regulation for Load Cells. This revision 

is planned to cover everything from the basic principles of R 60 (e.g., tolerances and accuracy classes) to exploring 

the addition of new requirements. The United States distributed a 1st Committee Draft of R 60 Parts 1 and 2 

(Metrological and technical requirements and Metrological controls and performance tests) to TC 9 members in 

August 2012. Comments on the 1 CD were due in November 2012 and were incorporated into a 2 CD. The 2 CD

TC 9/SC 2 Automatic Weighing Instruments (United Kingdom)

The DR of OIML R 106, Part 1, Automatic Rail Weighbridges, was approved by a d irect CIML online vote in 

April 2011, and R 106-1 was published in February 2012. The DR of R 106-2 was approved by the CIML in May 

2012 and is awaiting publication by the BIML. To receive copies of these documents or to obtain more information 

on the work of this subcommittee, please contact Mr. John Barton at (301) 975-4002 or john.barton@nist.gov. 

The Secretariat is in the process of revising OIML R 50, Continuous Totalizing Automatic Weighing Instruments

(Belt Weighers). The United States submitted comments on the 5 CD, Parts 1 and 2, of this Recommendation in 

October 2012. The Secretariat is now developing a DR of R 50-1 and R 50-2 for submission to the BIML as a 

CIML preliminary ballot. Comments have been returned on Part 3 of this Recommendation, and the Secretariat 

distributed the 2 CD of Part 3 in July 2013. For more information on this effort, please contact Mr. John Barton at 

(301) 975-4002 or john.barton@nist.gov. 

TC 17/SC 1 Humidity (China and United States)

The Co Secretariats are working with a small International Project Group to revise OIML R 59, Moisture Meters for 

Cereal Grains and Oilseeds. All drafts have been distributed to the USNWG, which for the most part is a subset of 

the National Type Evaluation Program Grain Analyzer Sector. A preliminary 6 CD was developed based on 

international comments received on the 5 CD, and a meeting of TC 17/SC 1 was held in Orlando, Florida, to address 

those comments. Per discussions during that meeting, Germany submitted suggestions for additional software 

requirements that were included in the 6 CD. The 6 CD was distributed in March 2013 with comments returned in

June 2013. Meetings of TC 17/SC 1 and TC 17/SC 8 will be held at NIST in Gaithersburg, July 23 - 25, 2013. 

Please contact Ms. G. Diane Lee at (301) 975-4405 or diane.lee@nist.gov if you would like to participate in this 

IWG.

TC 17/SC 8 Quality Analysis of Agricultural Products (Australia)

This subcommittee was formed to study the issues and write a working draft document Measuring Instruments for 

Protein Determination in Grains. Australia is the Secretariat. At a TC 17/SC 8 meeting hosted by NIST, the 

subcommittee discussed comments concerning the maximum permissible errors and harmonization of the 

TC 17/SC 8 Recommendation for protein with the TC 17/SC 1 Recommendation for moisture. International 

comments on the 2 CD were received and compiled. These comments were discussed at a meeting of TC 17/SC 8 in 

Orlando, Florida. The Secretariat completed the 3 CD based on the meeting discussion in Orlando. The United 

States submitted comments on the 3 CD in October 2012. Meetings of TC 17/SC 1 and TC 17/SC 8 was held at 

NIST in Gaithersburg, July 23 - 25, 2013. Please contact Ms. G. Diane Lee at (301) 975-4405 

or diane.lee@nist.gov, if you would like to participate in this IWG.

MAA and its implementation, please contact Dr. Charles Ehrlich at (301) 975-4834 or email charles.ehrlich@nist.gov. 

II. REPORT ON THE 47TH CIML MEETING IN BUCHAREST, ROMANIA IN 

OCTOBER 2012 

Mr. Peter Mason, CIML member from the United Kingdom and President of the CIML, opened the meeting and 

gave the President’s Report. 

Mr. Stephen Patoray, who has been serving as BIML Director since January 2011, provided several reports on 

financial and administrative matters at the BIML, including improvements that have been implemented since his 

arrival at the BIML. After consideration of an external auditor’s review of the 2011 OIML accounts, the CIML 

approved the 2011 accounts, and instructed its President to present them to the 14th OIML Conference.
BOD 2013 Final Report

Appendix A – Report on the Activities of OIML and Regional Legal Metrology Organizations

BOD - A7 

Mr. Patoray announced that there are seven new OIML Corresponding Members (all from Africa): Gambia, Liberia,

Malawi, Mauritania, Namibia, Nigeria, and Sierra Leone. He also announced that Colombia would soon become an 

OIML Member State. 

Dr. Grahame Harvey (Australia), currently serving as CIML 1st Vice President, announced that he was stepping 

down as the CIML Member from Australia due to financial considerations in Australia. Because of this, he also 

announced that he would not be running for reelection as CIML 1st Vice President. Discussions during the course of 

the CIML meeting eventually led to the appointment of the CIML 2nd Vice President (Roman Schwartz of PTB in 

Germany) to the position of 1st Vice President, with the decision to leave the position of 2nd Vice President unfilled

until a new election could be held at the 2013 CIML meeting.

It was decided that the OIML Translation Center already has enough money to cover paying for a backlog of 

English to French translations of OIML publications, and that in the future such translations should be paid out of a 

regular budget line item. No formal action was taken on this item.

The CIML adopted 25 Resolutions in Bucharest, Romania. The most noteworthy resolutions included:

• the proposed 2013-2016 budget was agreed to be forwarded to the OIML Conference (including a line 

item for indirect support to developing countries, in areas such as training videos);

• the draft revision of the OIML Financial regulations were adopted (with minor amendments);

• Corresponding Members may now participate as Observing Members on OIML Technical Committees, 

Subcommittees, and Project Groups (without having to pay a fee);

• the revision of OIML B 6 Directives for the Technical Work was approved (subject to any necessary 

editorial changes that the United States submitted);

• the extension of the OIML Mutual Acceptance Arrangement to include test data from manufacturer’s test 

labs (MTLs) on a voluntary basis was approved; and 

• the NIST wording pertaining to a Resolution on the New SI was accepted. 

The CIML approved the following Draft Publications in Bucharest, Romania: 

• Revision of OIML D 1 Considerations for a law on metrology, 

• Revision of OIML R 46 Electrical energy meters - Part 1: Metrological and technical requirements and 

Part 2: Metrological controls and performance tests, 

• Revision of OIML R 106-2 Automatic rail weighbridges - Part 2: Test report format. 

The CIML granted a special approval to OIML R 126, Evidential breath analyzers. Previously, in the preliminary 

ballot stage of R 126, the DR received five negative votes, some of which contained objections requiring substantial 

changes to the draft. Because the Secretariat of TC 17/SC 7 did not see any possibility to prepare a further draft that 

would remove the objections expressed in the preliminary ballot and because it was agreed that the revised text is a 

substantial improvement over the old version of OIML R 126 – the CIML decided to approve R 126 and then 

immediately start a revision process on the Recommendation.

III. REPORT ON THE 14TH OIML CONFERENCE IN BUCHAREST, ROMANIA, IN 

OCTOBER 2012 

The OIML Conference adopted 16 Resolutions in Bucharest, many of which had to do with formalizing the adoption 

of Resolutions from the CIML Meeting on budgetary, policy, and administrative matters.

IV. FUTURE OIML MEETINGS

The CIML accepted the invitation of Vietnam to host the 48th CIML Meeting next year in Ho Chi Minh City during 

the week of October 7 - 11, 2013.

The next OIML Conference will be held in 2016; the venue and dates for this Conference will be decided by the 

CIML at a future date.

V. REGIONAL LEGAL METROLOGY ORGANIZATIONS

Meeting of the Inter-American Metrology System (SIM) General Assembly and the SIM Legal Metrology 

Work Group (LMWG)

The SIM General Assembly (GA) was held in San Jose, Costa Rica, in November 2012. Mr. Jose Dajes Castro, 

from INDECOPI in Lima, Peru, serves as the SIM President. Mr. Marcos Senna at mjsenna@inmetro.gov.br, of 

INMETRO in Brazil, recently announced his resignation as the Chairman of the SIM LMWG. A new Chairman is

being sought. The organization is working to build capacity in legal metrology for SIM member countries. Please 

contact Mr. Ralph Richter at (301) 975-3997 or ralph.richter@nist.gov for more information on SIM.

Asia-Pacific Legal Metrology Forum (APLMF)

The 19th Meeting of APLMF was held November 5-9, 2012, in Cebu, The Philippines. Sixteen APLMF Member 

Economies participated in this meeting. The People’s Republic of China holds the Presidency and Secretariat of 

APLMF. Mr. Changcheng, APLMF President and Vice Minister of AQSIQ, chaired the meeting. APLMF activities 

are facilitated through its seven work groups. The most active is the work group on Training Coordination chaired 

by Australia.

The main objectives of APLMF are to coordinate regional training courses in legal metrology and to provide a 

forum for exchange of information among legal metrology authorities. The APLMF Secretariat spent a considerable 

amount of time, with the assistance of the United States, developing a proposal to obtain support from the AsiaPacific Economic Cooperation (APEC) – Trade and Investment Liberalization and Facilitation funding in order to 

support the delivery of the training in 2012. Changes in APEC priorities are making it more difficult to achieve 

funding. While feedback from the previously-held training courses has been positive, it is becoming clear that in 

order to continue to receive funding for the training, APLMF needs to do a more thorough job of assessing and 

documenting the impact of the training courses on the economies that receive the training.

Discussions in Cebu included a review of the events and training courses held since the last APLMF meeting; these 

included:

• An APLMF-APMP Joint Symposium on “Metrology for Economic and Social Sustainability” (Beijing);

• An APLMF Training Course on “Traceability in Rice Moisture Measurement” (Indonesia, ‘self-funded’);

• A Training Course on “Verification of Non-automatic Weighing Instruments (Papua New Guinea); 

• A Workshop on Technical Regulation and Harmonization of Bulk Fuel Trade Transactions in the APEC 

Region, Part 1 – “Improving the Custody Transfer of Liquid Fuel in the Asia-Pacific Region” (Singapore) 

(Ralph Richter of the NIST Office of Weights and Measures was the trainer); and

• A Workshop on Technical Regulation and Harmonization of Bulk Fuel Trade Transactions in the APEC 

Region, Part 2 – “Verification of bulk fuel using volumetric methods” (Thailand).

The United States was represented at the meeting in Cebu by Dr. Charles Ehrlich, who serves as Chairman of the 

APLMF work group on Mutual Recognition Arrangements. Dr. Ehrlich gave an extensive report and with updates 

on the OIML MAA and presented the United States Country Report. The 2013 APLMF meeting will be held in 

Yogyakarta, Indonesia, November 5 - 8, 2013.

AMC Draft Meeting Minutes

July 16, 2013 

Louisville, KY 

Call to Order

Chairman Robert Murnane called the meeting to order at 5:00 p.m.

Meeting Minutes

A copy of the 2013 Interim Meeting Minutes was distributed. These minutes were reviewed and a motion was made 

by Mr. Flocken and seconded by Mr. Johnson to approve the minutes as written. With no further discussion, the 

minutes were approved.

Financial Condition

A copy of the financial report was distributed; Chairman Murnane reported that the AMC fund has a balance of 

$26,602.49. Ms. Jucoch questioned what the plans are for the current balance. Chairman Murnane explained the 

process for scholarships, and how the money is approved through the online form for requests for training. There 

were also questions regarding where the money comes from to support the balance. Chairman Murnane reports that 

$15 from each membership is deposited in the AMC account.

Mr. Flocken stated that the annual dues are expected to increase the balance. Mr. Lewis reports one of the benefits 

of being a member is you get discount on NTEP certification fees. Chairman Murnane reported that there are 

discounts for testing as well.

Mr. Johnson reports there are currently 2156 members in the Conference; 803 associate members depending on the 

issue.

The financial report was reviewed and a motion was made by Mr. Johnson and seconded by Mr. Flocken to approve 

the financial report as written.

Board of Directors Report

Mr. Johnson, AMC representative on NCWM Board of Directors, gave a report regarding Board activities:

Mr. Johnson reports that the Conference has lost some very experienced weights and measures officials.

Terrence McBride had to resign from the BOD due to budget/travel issues with his program, and Clark Cooney of 

Oregon retired. 

The SWMA Meeting will be in Charleston, West Virginia, October 7 - 9, 2013, and the Measuring Sector Meeting 

will meet after the SWMA Meeting. 

AMC – Nothing new other than they are waiting for a response to a request for any kind of assistance on the new 

tool kit – whether funds or other support. 

Several states and NIST are requesting help with travel expenses for training. The states and NIST can provide the 

training, but lack of travel funds is limiting attendance at these important training programs. 

NIST – Package Inspection Training, help is needed in funding the purchase of materials (groceries) for these 

classes.
BOD 2013 Final Report

these groups are for a video and templates (CWMA). Mr. Benjamin will meet with the SWMA and WWMA this 

week. A task group will meet Sunday afternoon.

NTEP Staffing – NCWM advertised a new position for additional NTEP personnel. There is a lot of interest and 

candidates.

Professional Development Committee (PDC) Report

Mr. Steve Grabski mentioned that getting the trainers out traveling will be a big help. Chairman Murane mentions 

that he appreciates the work that the PDC has completed. Pretty much everyone present at the Conference for

Old Business

Mr. Gurney reports there is a request for training for the Northern Mariana Islands a U.S. territory; they are looking 

for training on package inspections. Mr. Don Onwiler and NIST put their heads together on who could do this 

training and decided on Mr. Gurney. T he Northern Mariana Islands will be putting a request together for 

approximately $4300; they want the AMC to think it over.

Chairmen Munane asked, “Does NIST have an online course for the training? Are the Northern Mariana Islands 

members of the Conference? Could the training be completed through a webinar or WebEx?” Chairmen Murnane 
BOD 2013 Final Report

Appendix B – AMC Agenda and Draft Minutes

BOD - B4 

asks that they check into online training and then apply online. Mr. Gurney stated originally there were going to be 

approximately 25 people needing training, and then there were some issues with getting all the folks to the training. 

Mr. Flocken stated that the more information that can be provided in the application the better and it can be look at 

as a cost vs. value. Mr. Lewis states that they should make sure they request enough funds; AMC will not approve 

extra funds. Chairmen Murnane ask that Mr. Gurney get the information regarding WebEx, Webinar, NIST and 

online training, put in the application and the Committee will vote on it. 

Mr. Oppermann believes that it is a worthwhile request. Chairmen Murnane asked if NIST is available for the 

training. 

Mr. Onwiler reports that the Northern Mariana Islands does not have a NCWM membership at this time. Mr. 

Onwiler stated that NCWM does have a WebEx account that he uses to host meetings for NCWM groups. Chairmen 

Murnane reported that there may be an issue if they are not members, and Mr. Lewis stated not all the inspectors that 

are trained with AMC funds are members. 

Mr. Gurney will get the information for the requested training and put in a request for funds when all details become 

available.

New Business

Chairman Murnane stated that Ms. Julie Quinn (Minnesota) is requesting money to send people on travel. Mr. 

Floken stated that we will pay for travel for trainers, but not for travel for people to get training. 

Chairmen Murnane states that it’s difficult to control. You don’t know what the benefits are and what we will get 

out of it. We will pay for trainers to travel and facilities but not for trainees to get training. 

Chairmen Murnane stated we will buy the items for packing checking and tools. 

Chairmen Murnane asked, “Is there something that the AMC wants to do for the NCWM’s 100th Meeting?” Mr. 

Lewis asked, “Do we want to make a pin or a paper weight?” 

Mr. Flocken stated that the SMA was looking into sponsoring a lunch but we cannot do that. The Conference will 

not accept sponsorship.

Mr. Flocken stated he would rather spend the money on training as it’s designed. 

Mr. Onwiler reported that the Conference will not accept any sponsorship, the policy is very clear, if a group wants 

to go off and do something on their own, NCWM cannot endorse it and that activity would violate a gentlemen’s 

agreement against hospitality suites. The work group is asking to suspend the rules for one event. The decision has 

not been made. 

Chairmen Murnane stated he would like for the policy to stand, if the news media were to get ahold of it and spin it 

the wrong way it would look very bad for the Conference. 

Mr. Onwiler stated NIST put together the very first handbook standards adopted by NCWM as a gift to the attendees 

of NCWM’s 100-Year Anniversary Event. 

Is there a difference between providing food and beverage vs. providing a gift? Mr. Onwiler does not know if that 

would be allowed, but that’s still sponsorship, and it’s a board decision. Mr. Onwiler encourages that we voice 

comments to the Board regarding sponsorship.

Mr. Lewis states members are welcome to set up their own booth and give away items. Mr. Onwiler stated that 

NCWM is not sponsoring it. 

Mr. Onwiler wants the 100th to be a success.
BOD 2013 Final Report

Appendix B – AMC Agenda and Draft Minutes

BOD - B5 

Chairmen Murnane does not want to relax the rules, and we want to stay above reproach at all times. We don’t want 

companies to have hospitality suites serving shrimp cocktails all night that’s negative for the Conference. 

Mr. Flocken stated that he supports what Chairmen Murnane says. Mr. Flocken stated giving away a gift or pin is 

not money well spent. We need to save the money for training opportunities. 

Ms. Hemida asked, “Can we call suppliers and put on training for the Conference?” Chairmen Murnane stated that 

the training would be more beneficial at the regional level. Most of the folks attending the National meeting are not 

the ones needing training. 

Ms. Hemida asks why not come up with something about the history of weights and measures past 100 years of 

events. How did we get to where we are now – a video or a DVD of five to seven minutes of the history? 

Chairmen Murnane asked how about weights and measure history as a video, understanding the history of weights 

and measures. 

Mr. Oppermann reported that Mr. Onwiler told him the estimated cost is $1000/min. We would not need a very 

lengthy video. 

Ms. Juroch asked if the Smithsonian has anything on the history of scales. 

You have to touch everything, scales, gas pumps, all parts of weights and measures. 

Chairmen Murnane and the group liked the DVD idea; Ms. Hemida will get with Mr. Onwiler and let us know on 

the feedback. 

Adjournment

Mr. Oppermann said thank you Chairmen Murnane for his effort and his contribution. 

Mr. Lewis moved to adjourn the meeting, a motion was made, and the meeting was adjourned at 5:58 p.m.

Respectfully submitted by, 

Mr. David Calix

Wisconsin Weights and Measures

200 INTRODUCTION

This is the report of the Laws and Regulations Committee (hereinafter referred to as the “Committee”) for the 98th

Annual Meeting of the National Conference on Weights and Measures (NCWM). T his report is based on the 

Interim Report offered in the NCWM Publication 16, “Committee Reports,” testimony at public hearings, comments 

received from the regional weights and measures associations and other parties, the NCWM 2013 Online Position 

Forum, the addendum sheets issued at the Annual Meeting, and actions taken by the membership at the voting 

session of the Annual Meeting. The Informational items shown below were adopted as presented when this report 

was approved.

Table A identifies the agenda items and appendix items. The agenda items in the Report are identified by Reference 

Key Number, title, and page number. The first three digits of the Reference Key Numbers of the items are assigned 

from the subject series listed below. Voting items are indicated with a “V” after the item number. Items marked 

with an “I” are Informational. I tems marked with a “ D” are Developing items. T he developing designation 

indicates an item has merit; however, the item is returned to the submitter for further development before any further 

action is taken by the Committee. Items marked “W” have been Withdrawn from consideration. Table B provides a 

list of acronyms used in this report, and Table C provides a summary of the results of the voting on the Committee’s 

items and the report in its entirety. 

This report contains recommendations to amend National Institute of Standards and Technology (NIST) 

Handbook 130, 2013 Edition, “Uniform Laws and Regulations,” or NIST Handbook 133, “Checking the Net 

Contents of Packaged Goods,” Fourth Edition (January 2013). Proposed revisions to the handbook(s) are shown in 

bold face print by striking out information to be deleted and underlining information to be added. New items 

proposed for the handbooks are designated as such and shown in bold face print. Text presented for information 

only is shown in italic print. When used in this report, the term “weight” means “mass.”

Note: The policy of NIST is to use metric units of measurement in all of its publications; however, 

recommendations received by the NCWM technical committees have been printed in this publication as they were 

submitted and, therefore, some may contain only reference to inch-pound units.

221 NIST HANDBOOK 130 – WEIGHTS AND MEASURES LAW

221-1 V Section 1. Definitions 

(This item was adopted.) 

Source: 

National Institute of Standards and Technology, Office of Weights and Measures (OWM) (2012)

Purpose: 

Bring the Uniform Weights and Measures Law into agreement with current international agreement on terminology 

on these metrology-related definitions. 

Item Under Consideration: 

Amend NIST Handbook 130, Uniform Weights and Measures Law as follows: 

1.14. Calibration. – An A set of operations which establishes, operation that, under specified conditions,

the in a first step, establishes a relation relationship between the quantity values indicated by a measuring 

instrument or measuring system, or values represented by a material measure, and the corresponding 

known values of a measurand. with measurement uncertainties provided by measurement standards and 

corresponding indications with associated measurement uncertainties and, in a second step, uses this 

information to establish a relation for obtaining a measurement result from an indication.

(Added 2005) (Amended 2013) 

1.15. Metrological Traceability. – The property of the a measurement result of a measurement or the 

value of a standard whereby the result it can be related to a reference stated references, usually national 

or international standards, through a documented an unbroken chain of calibrations, each contributing to 

the measurement uncertainty. comparisons all having stated uncertainties. 

(Added 2005) (Amended 2013) 

1.16. Measurement Uncertainty. – A non-negative parameter associated with the result of a measurement 

that characterizes characterizing the dispersion of the quantity values that could reasonably be being

attributed to a measurand, the measurance. based on the information used.

(Added 2005) (Amended 2013) 

1.19. Standard, Reference Measurement. – A measurement standard, generally of the highest 

metrological quality available at a given location, from which measurements made at that location are 

derived. designated for the calibration of other measurement standards for quantities of a given kind in a 

given organization or at a given location. The term “reference measurement standards” usually means the 

physical standards of the state that serve as the legal reference from which all other standards for weights and 

measures within that state are derived.

(Added 2005) (Amended 2013)
L&R Committee 2013 Final Report

L&R - 6 

1.20. Standard, Working Measurement. – A measurement standard that is usually calibrated against a 

reference standard, and is used routinely to calibrate or check material measures, measuring instruments 

or reference materials. verify measuring instruments or measuring systems. The term “working 

measurement standards” means the physical standards that are traceable to the reference standards through 

comparisons calibrations or verifications, using acceptable laboratory procedures, and used in the 

enforcement of weights and measures laws and regulations.

(Added 2005) (Amended 2013) 

1.21. Metrological Traceability Chain. – Sequence of measurement standards and calibrations that is 

used to relate a measurement result to a reference.

(Added 2013) 

1.22. Metrological Traceability to a Measurement Unit. – Metrological traceability where the reference 

is the definition of a measurement unit through its practical realization.

(Added 2013) 

Background/Discussion: 

The 1993 version of the International Vocabulary of Metrology (VIM) was updated in 2008 to reflect changes in 

international agreement about several of the key definitions it contains, in order to better align the definitions with 

the philosophy of the Guide to the Expression of Uncertainty in Measurement (GUM). The current definitions of 

five entries in the Uniform Weights and Measures Law (UWML) were taken from the 1993 version of the VIM, and 

so do not reflect the changes introduced in the 2008 version of the VIM. The changes proposed below are to update 

those five entries so that they reflect current international agreement on terminology. Two new definitions that are 

related to the other five definitions are also being proposed to be added. 

By incorporating these seven definitions, the UWML will be brought into agreement with current international 

agreement on these metrology-related definitions. Since the GUM is referenced in ISO/IEC 17025 (General 

requirements for the competence of testing and calibration laboratories), which is used as the basis for accrediting 

State metrology laboratories, incorporating these updated definitions into the UWML will also underpin the longterm harmonization of vocabulary between the NCWM and the international standards used to regulate the testing 

and calibration laboratories upon which NCWM depends (such as for National Type Evaluation Program [NTEP]). 

Harmonization of NCWM terminology with internationally accepted terminology helps promote global acceptance 

of U.S. products abroad. Proposed modifications could interfere with commonly used NCWM 

terminology/concepts, but the presenter of this proposal believes that is not the case here.

Previous Item Under Consideration:

1.14. Calibration. – An set of operations which establishes, under specified conditions, the relationship 

between values indicated by a measuring instrument or measuring system, or values represented by a 

material measure, and the corresponding known values of a measurand. operation that, under specified 

conditions, in a first step, establishes a relation between the quantity values with measurement 

uncertainties provided by measurement standards and corresponding indications with associated 

measurement uncertainties and, in a second step, uses this information to establish a relation for 

obtaining a measurement result from an indication.

NOTE 1: A calibration may be expressed by a statement, calibration function, calibration diagram, 

calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative 

correction of the indication with associated measurement uncertainty.

NOTE 2: Calibration should not be confused with adjustment of a measuring system, often mistakenly 

called “self-calibration,” nor with verification of calibration.
L&R Committee 2013 Final Report

L&R - 7 

NOTE 3: Often, the first step alone in the above definition is perceived as being calibration.

(Added 2005) (Amended 20XX) 

1.15. Metrological Traceability. – The property of the result of a measurement or the value of a standard 

whereby it can be related to stated references, usually national or international standards, through an 

unbroken chain of comparisons all having stated uncertainties. property of a measurement result 

whereby the result can be related to a reference through a documented unbroken chain of calibrations, 

each contributing to the measurement uncertainty.

NOTE 1: For this definition, a “reference” can be a definition of a measurement unit through its 

practical realization, or a measurement procedure including the measurement unit for a non-ordinal 

quantity, or a measurement standard.

NOTE 2: Metrological traceability requires an established calibration hierarchy.

NOTE 3: Specification of the reference must include the time at which this reference was used in 

establishing the calibration hierarchy, along with any other relevant metrological information about the 

reference, such as when the first calibration in the calibration hierarchy was performed.

NOTE 4: For measurements with more than one input quantity in the measurement model, each of the 

input quantity values should itself be metrologically traceable and the calibration hierarchy involved may 

form a branched structure or a network. The effort involved in establishing metrological traceability for 

each input quantity value should be commensurate with its relative contribution to the measurement 

result.

NOTE 5: Metrological traceability of a measurement result does not ensure that the measurement 

uncertainty is adequate for a given purpose or that there is an absence of mistakes.

NOTE 6: A comparison between two measurement standards may be viewed as a calibration if the 

comparison is used to check and, if necessary, correct the quantity value and measurement uncertainty 

attributed to one of the measurement standards.

NOTE 7: The ILAC considers the elements for confirming metrological traceability to be an unbroken 

metrological traceability chain to an international measurement standard or a national measurement 

standard, a documented measurement uncertainty, a documented measurement procedure, accredited 

technical competence, metrological traceability to the SI, and calibration intervals (see ILAC P 10:2002).

NOTE 8: The abbreviated term “traceability” is sometimes used to mean “metrological traceability” as 

well as other concepts, such as “sample traceability” or “document traceability” or “instrument 

traceability” or “material traceability”, where the history (“trace”) of an item is meant. Therefore, the 

full term of “metrological traceability” is preferred if there is any risk of confusion.

(Added 2005) (Amended 20XX)

1.16. Measurement Uncertainty. – A parameter associated with the result of a measurement that 

characterizes the dispersion of the values that could reasonably be attributed to the measurance. nonnegative parameter characterizing the dispersion of the quantity values being attributed to a measurand, 

based on the information used.

NOTE 1: Measurement uncertainty includes components arising from systematic effects, such as 

components associated with corrections and the assigned quantity values of measurement standards, as 

well as the definitional uncertainty. Sometimes estimated systematic effects are not corrected for but, 

instead, associated measurement uncertainty components are incorporated.
L&R Committee 2013 Final Report

L&R - 8 

NOTE 2: The parameter may be, for example, a standard deviation called standard measurement 

uncertainty (or a specified multiple of it), or the half-width of an interval, having a stated coverage 

probability.

NOTE 3: Measurement uncertainty comprises, in general, many components. Some of these may be 

evaluated by Type A evaluation of measurement uncertainty from the statistical distribution of the 

quantity values from series of measurements and can be characterized by standard deviations. The other 

components, which may be evaluated by Type B evaluation of measurement uncertainty, can also be 

characterized by standard deviations, evaluated from probability density functions based on experience 

or other information.

NOTE 4: In general, for a given set of information, it is understood that the measurement uncertainty is 

associated with a stated quantity value attributed to the measurand. A modification of this value results 

in a modification of the associated uncertainty.

(Added 2005) (Amended 20XX)

1.19. Standard, Reference Measurement. – A standard, generally of the highest metrological quality

available at a given location, from which measurements made at that location are derived. measurement 

standard designated for the calibration of other measurement standards for quantities of a given kind in 

a given organization or at a given location. The term “reference standards” means the physical standards of 

the state that serve as the legal reference from which all other standards for weights and measures within that 

state are derived.

(Added 2005) (Amended 20XX)

1.20. Standard, Working Measurement. – A standard that is usually calibrated against a reference 

standard, and is used routinely to calibrate or check material measures, measuring instruments or 

reference materials. measurement standard that is used routinely to calibrate or verify measuring

instruments or measuring systems. The term “working standards” means the physical standards that are 

traceable to the reference standards through comparisons, using acceptable laboratory procedures, and used in 

the enforcement of weights and measures laws and regulations.

NOTE 1: A working measurement standard is usually calibrated with respect to a reference 

measurement standard.

NOTE 2: In relation to verification, the terms “check standard” or “control standard” are also 

sometimes used.

(Added 2005) (Amended 20XX)

1.21. Metrological Traceability Chain. – Sequence of measurement standards and calibrations that is 

used to relate a measurement result to a reference.

NOTE 1: A metrological traceability chain is defined through a calibration hierarchy.

NOTE 2: A metrological traceability chain is used to establish metrological traceability of a 

measurement result.

NOTE 3: A comparison between two measurement standards may be viewed as a calibration if the 

comparison is used to check and, if necessary, correct the quantity value and measurement uncertainty 

attributed to one of the measurement standards.

(Added 20XX)

1.22. Metrological Traceability to a Measurement Unit. – Metrological traceability where the reference 

is the definition of a measurement unit through its practical realization.
L&R Committee 2013 Final Report

L&R - 9 

NOTE 1: The expression “traceability to the SI” means “metrological traceability to a measurement unit 

of the International System of Units”.

(Added 20XX)

2011 CWMA Interim Meeting: Four officials commented that they do not support this proposal and asked why the 

international vocabulary could not align with NCWM. An official asked that NIST, OWM provide examples of 

problems caused by the lack of alignment with these two publications. CWMA did not forward the item to NCWM. 

2011 WWMA Annual Meeting: An official supported the efforts to harmonize the relationship with international 

counterparts and believes this item should be supported on those grounds. The Committee supported the idea of the 

proposal but would like to have staff review this item before proceeding. WWMA forwarded the item to NCWM, 

recommending it as an Informational Item. 

2011 NEWMA Interim Meeting: T he Committee recognized that uniformity of definitions in the international 

marketplace will result in less confusion. N EWMA forwarded the item to NCWM, recommending it as a 

Developing Item. 

2011 SWMA Annual Meeting: No comments were heard. The Committee recommended allowing more time for 

internal review by members. SWMA forwarded the item to NCWM, recommends it be forwarded to NCWM as an 

Informational Item. 

2012 NCWM Interim Meeting: T he submitter explained that the proposal allows for alignment with the 

international definitions. There is concern that the international language does not conform to existing language in 

NIST Handbook 130. The language appears to be too complicated and could cause misinterpretation. T he 

Committee recommended that this language be returned to the submitter for language review and formatting. They 

would like the submitter to share the revised document at the 2012 CWMA and NEWMA Annual meetings. The 

2012 L&R Committee designated this item as a Developing Item.

2012 NEWMA Annual Meeting: NEWMA supported this item and recommended that the item remain as a 

Developing Item.

2012 CWMA Annual Meeting: A NIST Technical Advisor submitted modified definitions and provided additional 

background information as follows:

Background of each definition (May 2012)

1.14. Calibration: Justification to amend the definition:

This revision updates the current definition by clarifying that a calibration not only involves comparing

indications of measuring instruments with corresponding values (and uncertainties) of measurement standards, 

but also involves using these comparisons in an “inverse” manner, in order to be able to assign a measured 

value and measurement uncertainty to an item being measured by the measuring instrument, based on the 

indication of the measuring instrument. By updating this definition, UWML will recognize that calibration 

involves a two-step process.

1.15. Metrological Traceability: Justification to amend the definition:

This revision will update the current definition in four significant ways. First, in the 2008 VIM, “measurement 

result” means a value and an uncertainty (not just a value, as it meant in the 1993 VIM), so that traceability now 

applies to both the value and the uncertainty. Second, it is recognized that any acceptable “reference” can be 

used, and it doesn’t have to be a n ational or international standard. T hird, the unbroken chain has to be 

documented, which wasn’t specified in the 1993 definition. And fourth, the chain is a chain of calibrations, and 

not just comparisons. This is to recognize that a comparison alone is not sufficient for traceability, since a 

comparison does not result in values being transferred along the chain (as a calibration does). Also, the term 

“Metrological” is added in front of “Traceability” in order to distinguish this type of traceability from other 

types (e.g., document traceability). By updating this definition, the UWML will be consistent with international 

practice, such as used in documents from the International Organization for Standardization (ISO) and 
L&R Committee 2013 Final Report

L&R - 10

International Electrotechnical Commission (IEC) that pertain to accreditation requirements for (state) metrology 

laboratories (e.g., ISO/IEC 17025).

1.16. Measurement Uncertainty: Justification to amend the definition:

This revision updates the current definition by first clarifying that a measurement uncertainty cannot be 

negative, and also by removing “that could reasonably be attributed”, which some people found to be confusing. 

The term “Measurement” was added in order to distinguish this type of uncertainty from other types. T he 

advantage to updating this definition is that the revisions will bring it in to agreement with the 2008 VIM 

definition. 

1.19. Standard, Reference Measurement: Justification to amend the definition:

This revision will update the current definition in two ways. F irst, it would no longer be required that a 

reference measurement standard be of the highest quality available (for example, it could be lower in a 

metrological traceability chain). Second, it is specified that a reference measurement standard is intended to be 

used for calibration of other measurement standards (as opposed to being used to make routine measurements). 

The term “Measurement” was added to the term in order to distinguish this type of reference standard from 

other types. Updating this definition will reflect current international agreement about reference measurement 

standards that is consistent with the 2008 VIM.

1.20. Standard, Working Measurement: Justification to amend the definition

This revision will update the current definition in two ways. First, a working standard would no longer be 

required to be directly calibrated by a r eference standard (it could, for example, be calibrated by another 

working standard). Also, this revision will clarify that a working standard can be used for both calibration and 

verification. The word “Measurement” was added in order to distinguish this type of standard from other types 

of working standards. By updating this definition, the UWML will reflect current international agreement about 

working measurement standards that is consistent with the 2008 VIM.

1.21. Metrological Traceability Chain: Justification to add the following definition to the UWML:

This is a new definition for that is intended to support the revision to the definition of “metrological 

traceability” by explaining what is meant in the definition by “chain.” By adding this definition, the UWML 

will reflect current international agreement on traceability that is consistent with ISO and IEC documents that 

pertain to accreditation requirements for (state) metrology laboratories.

1.22. Metrological Traceability to a Measurement Unit: Justification to add the following definition to the 

UWML:

This is a new definition that is intended to support the revision to the definition of “metrological traceability” by 

explaining what is meant by the expression “traceability to the SI”. For example, “(metrological) traceability to 

the SI” means metrological traceability to the definition of the measurement unit “kilogram” (kg) through the 

practical realization of the kg at NIST, obtained by calibration of a NIST mass artifact, having a mass of about 

1 kg, against the international kilogram in Paris. By adding this definition to the UWML, it will reflect current 

international agreement on traceability that is consistent with ISO and IEC documents that pertain to 

accreditation requirements for (state) metrology laboratories.

CWMA requested that the submitter of the proposal provide a presentation at the 2012 NCWM Annual Meeting to 

brief the Conference on the changes and effects to each definition to help provide clarity. CWMA recommended 

that the item remain as a Developing Item. 

2012 NCWM Annual Meeting: Dr. Charles Ehrlich (NIST, OWM) clarified the purpose of this item. He will 

provide a presentation at the 2013 NCWM Interim meeting that will further explain each proposed definition. The 

Committee updated its report to include Dr. Ehrlich’s explanations for each definition as presented at the CWMA 

Annual Meeting and updated the Item under Consideration to reflect the most recent modifications by Dr. Ehrlich.

2012 WWMA Annual Meeting: There was concern that the proposed definitions are too technical/scientific. The 

Uniform Weights and Measures Law is for the commercial area. I t would be difficult to explain the proposed 

definitions to a layman or lawyer. The Committee believed this proposal was fully developed. There was also 

concern that NCWM would be adapting to foreign language standards. Dr. Ehrlich will make a presentation at the 
L&R Committee 2013 Final Report

L&R - 11

NCWM 2013 Interim meeting and will perhaps respond to the concerns. The proposed language would greatly 

impact the laboratory. Most state laboratories have budgetary constraints and may not be able to conform without 

repercussions. It may also impact some laboratory accreditations/certifications. The Committee recommended that 

the states provide additional input to Mr. Raymond Johnson (New Mexico) and Tim Lloyd (Montana) prior to the 

January 2013 Interim Meeting. WWMA recommended that the item be an Informational Item.

2012 SWMA Annual Meeting: A weights and measures consultant commented that the current definitions are very 

well thought out and carefully worded definitions. Concern was expressed with the highly technical nature of the 

definitions and whether these definitions should be in weights and measures law. The average regulator may not be 

able to decipher the meaning of the definitions or properly interpret and apply them. It was suggested that the 

definitions may be more appropriate in metrology manuals. SWMA recommended that the item be a Developing 

Item.

2013 NCWM Interim Meeting: Dr. Ehrlich gave a brief presentation addressing concerns that were raised at the 

Regional Meetings. The Committee determined that this item was developed and proposed it be a Voting Item.

At the 2013 NEWMA Meeting: A comment was heard that these definitions are more than metrology and they also 

involve field operations. NEWMA supported this proposal as written and recommended that it be a Voting Item. 

At the 2013 CWMA Meeting: There were no comments on this item, and it was recommended as a Voting Item.

At the 2013 NCWM Annual Meeting: The Committee recommended the item be presented for a Vote.

Interested parties should contact Dr. Charles Ehrlich (NIST, OWM), at (301) 975-4834 or charles.ehrlich@nist.gov, 

or contact Ms. Lisa Warfield (NIST, OWM) at (301) 975-3308 or lisa.warfield@nist.gov. 

231 NIST HANDBOOK 130 – UNIFORM PACKAGING AND LABELING 

REGULATION

231-1 W Sections 6.12. Supplementary Quantity Declarations and 6.14. Qualification of

Declaration Prohibited 

(This item was withdrawn.) 

Source: 

Central Weights and Measures Association (2011) 

Purpose: 

Provide clearer language to guide industry and state officials when federal agencies are inconsistent in their 

interpretations. 

Item Under Consideration: 

Amend NIST Handbook 130, Uniform Packaging and Labeling Regulation as follows: 

6.12. Supplementary Quantity Declarations. – The required quantity declaration may be supplemented by 

one or more declarations of weight, measure, or count, such declaration appearing other than on a principal 

display panel. Such supplemental statement of quantity of contents shall not include any term qualifying a unit 

of weight, measure, or count that tends to exaggerate the amount of commodity contained in the package (e.g., 

“giant” quart, “larger” liter, “full” gallon, “when packed,” “minimum,” “equivalent,” “lasts the same as,” or 

words of similar import).

(Amended 20XX)
L&R Committee 2013 Final Report

L&R - 12

6.14. Qualification of Declaration Prohibited. – In no case shall any declaration of quantity be qualified by 

the addition of the words “when packed,” “minimum,” or “not less than “equivalent,” or “lasts the same as”

or any words of similar import (e.g., “approximately”), nor shall any unit of weight, measure, or count be 

qualified by any term (such as “jumbo “giant,” “full,” or the like) that tends to exaggerate the amount of 

commodity.

(Amended 1998, Amended 20XX) 

Background/Discussion: 

Manufacturers are using the terms such as “equivalent” or “lasts the same as” to qualify net weight statements. 

Clearer language is needed to provide consumers with better information. Industries and state officials need better 

guidance for product labeling. The Federal Trade Commission (FTC) does not consider the terms “equivalent,” or 

“lasts the same as” to be exaggerated or misleading.

2010 CWMA Interim Meeting: A n official presented an example of a label (below) that was perceived as 

mislabeled. It was agreed that no conflicting information regarding the net weight statement should be in the lower 

one-third of the principal display panel. CWMA forwarded the item to NCWM, recommending it as a Voting Item. 

 
L&R Committee 2013 Final Report

L&R - 13

 

2011 NCWM Interim Meeting: It was reported that this language was lifted straight out of the Fair Packaging and 

Labeling Act (FPLA) and regulators might encounter problems with their investigations if the language is modified. 

The NIST Technical Advisor commented that the language “lasts the same as” or “equivalent” is in the marketplace, 

which may be misleading to consumers. The Committee was reminded that the lower 30 % of the principal display 

panel should be free of supplementary quantity declarations as specified in the Uniform Packaging and Labeling 

Regulation (UPLR) Section 6.12. Supplementary Quantity Declarations. 

The NIST Technical Advisor remarked that the section was amended in 1998 to include the term “approximately” 

(which is not included in the FPLA) as a prohibited term. There has been no indication that the differences between 

the UPLR and FPLA are being challenged. It was also recommended that FTC be notified that this is an issue 

before the Conference. T he Committee received a l etter from a manufacturer stating that the company will 

voluntarily remove “lasts the same as” from their package label. The 2011 L&R Committee designated this item as 

an Informational Item to allow for review and comment by all regions.

2011 NEWMA Annual Meeting: There was a recommendation to obtain additional data from the submitter of the 

proposal along with clarification from the FTC on their letter dated November 4, 2010 (refer to the Report of the 

96th National Conference on Weights and Measures [SP 1125, 2011], Appendix A). No additional comments were 

heard on this item. The NEWMA L&R Committee recommended that this item be Informational.

2011 CWMA Annual Meeting: The submitter of the proposal commented that the terms “last the same as” and 

“equivalent to” are not quantity statements and should not be in the net quantity of the principle display panel area. 

The CWMA L&R Committee finds that this will be helpful for enforcement issues and recommended that this item 

be Informational.

2011 NCWM Annual Meeting: There were no comments heard on this item. The Committee received a letter (refer 

to the Report of the 96th National Conference on Weights and Measures [SP 1125, 2011], Appendix A) from Clorox, 

stating the term “lasts the same as” is being removed from their packaging. The Committee would like to receive 

additional input from the fall 2011 regional meetings on this item.
L&R Committee 2013 Final Report

L&R - 14

2011 CWMA Interim Meeting: Several officials voiced support of the item and wanted clear cut guidelines for 

enforcement. Additionally, officials would like to see the FTC follow suit in federal law. O ne official

recommended that the item be referred to the Package and Labeling Subcommittee (PALS). CWMA supports this 

item and recommends that it be a Voting Item. 

2011 WWMA Annual Meeting: There were no comments. The Committee concurs with the FTC findings that the 

terms are not misleading. The added terms are deemed a q uality statement rather than a quantity statement. 

WWMA recommended that the item be Withdrawn.

2011 NEWMA Interim Meeting: N o comments were made and the Committee maintained a neutral position. 

NEWMA recommended that the item remain as an Informational Item. 

2011 SWMA Annual Meeting: There were no comments heard from the floor. T he Committee supported the 

proposal as written. SWMA recommended that the item be a Voting Item. 

2012 NCWM Interim Meeting: An industry representative commented that exaggerated and misleading terms need 

to be addressed. He contends that in the marketplace it is becoming commonplace to see supplemental information 

appearing on the front of the principal display panel. Mr. Guay, PALS Chair, recommended that PALS develop this 

item to provide additional guidance. The NCWM L&R Committee designated this item as an Informational Item

and assigned its development to PALS.

NEWMA and the CWMA Annual Meetings: Both regions supported the development of this item through PALS. 

At the CWMA Meeting Mr. Guay remarked that the PALS had just been formed and have not had the opportunity to 

meet. During the 2012 NCWM Annual Meeting, Mr. Guay provided the Committee with governing principles 

regarding claims on packages and to develop a series of recommendations regarding best practices for these types of 

label statements 

2012 CWMA Interim Meeting: The NCWM L&R Committee member from the CWMA remarked that PALS was 

assigned to develop this item by the NCWM L&R Committee. A regulatory official asked the Committee to press 

forward with this item because problems were growing. CWMA supported this item and recommended that the 

item remain as an Informational Item and that PALS should address the proposal since compliance issues have been 

identified. 

2012 WWMA Annual Meeting: A regulatory official commented that some terms are “performance” based, but to a 

quantity statement. P ALS Chairman, Mr. Guay recommended that the item be renamed and reworded. The 

Committee believed the intent of the item is valid; however, after hearing Mr. Guay’s comments it agrees the item 

needs to be rewritten. T he Committee’s concurs with FTC findings that the terms are not misleading. T he 

Committee recommends that PALS continue to work on such issues and once developed PALS should submit a new 

proposal. WWMA recommended that the item be Withdrawn. 

2012 SWMA Annual Meeting: S WMA withheld comment until the PALS reviews the item and makes a 

recommendation. SMWA recommended that the item be an Informational Item.

2012 NEWM Interim Meeting: NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: Mr. Guay recommended that this item be Withdrawn because they have changed 

and expanded the scope to include other types of quantity and quality statements. PALS will submit a similar 

proposal in the future once it is developed. The Committee concurs with PALS and Withdrew this item in its 

entirety. 

2013 CWMA and NEWMA Annual Meetings: Both associations were in support of the Withdrawal of this item. 

At the 2013 NCWM Annual Meeting no further action was taken by the Committee since the Committee had 

previously agreed to “Withdraw” the item.

231-2 I Section 10.3. Aerosols and Similar Pressurized Containers

Source: 

Commonwealth of Massachusetts Division of Standards (2012)

Purpose: 

To allow the quantity statement in terms of weight for packages utilizing the Bag on Valve (BOV) technology where 

the propellant is not expelled when the valve is activated. NIST Handbook 130, Section 10.3. Aerosols and Similar 

Pressurized Containers require aerosols and similar pressurized containers that expel the propellant along with the 

product to disclose the net quantity in terms of weight.

Item Under Consideration: 

Amend NIST Handbook 130, Uniform Packaging and Labeling Regulation as follows:

10.3. Aerosols and Similar Pressurized Containers. – The declaration of quantity on an aerosol package 

including Bag on Valve (BOV) technology and other similar pressurized packages shall disclose the net 

quantity of the commodity (including propellant), in terms of weight, that will be expelled when the instructions 

for use as shown on the container are followed.

Note: Packages that utilize the Bag on Valve (BOV) technology shall be enforceable after 

month/day/20XX.

(Amended 20XX)

Background/Discussion: 

There are a number of products in the marketplace bearing quantity statements in terms of fluid measure that utilize 

the BOV technology. Packages using BOV technology are non-aerosol by definition because the propellant is not 

dispensed with the product. Consumers cannot do price and quantity comparison between product packaged using 

BOV technology and similar product in aerosol packaging because the aerosol packaged product includes the 

propellant in the net weight and the propellant is dispensed with the product. In the example below, two similar 

products are pictured, however the one on the left is labeled by net weight, and the one on the right is labeled by 

liquid measure. 

BOV technology is environmentally 

friendlier because the propellant is not 

dispensed with the product. Products 

utilizing the BOV technology only 

expel the product as the product is 

contained in a bag which is surrounded 

by the propellant inside the container. 

In April 2011, NIST, OWM received a 

letter supporting labeling of certain 

products such as the “Pure Citrus” 

product pictured above by liquid 

measure.

2011 CWMA Interim Meeting: The Committee agreed that the proposal did not include a specific recommendation 

for the language for the amendment to NIST Handbook 130, Section 10.3. Aerosols and Similar Pressurized 

Containers. The Committee did not forward the item to NCWM and recommended that the item be returned to the 

submitter for Development. 
L&R Committee 2013 Final Report

L&R - 16

2011 WWMA Annual Meeting: A comment from industry stated there are products in the marketplace that are 

similar but delivered in a d ifferent fashion. This should be looked at to account for new technology in the 

marketplace. The NIST Technical Advisor read from the NEWMA 2011 Annual Meeting Report that recommends 

the words “non-aerosol” be printed on the label so that inspectors know to test by fluid measure. The Committee

believes there may be some confusion to the different unit pricing units but that consumers will be able to determine 

that there is new technology to expel the product. BOV technology exists in the marketplace and a proper method of 

sale is needed. The Committee recommended forwarding the item to NCWM as a Voting Item with the language 

modifications reflected below:

10.3. Aerosols and Similar Pressurized Containers. – The declaration of quantity on an aerosol package and 

on a s imilar pressurized package shall disclose the net quantity of the commodity (including propellant), in 

terms of weight, that will be expelled when the instructions for use as shown on the container are followed. 

10.3.1. Products labeled non Aerosols in Similar Pressurized Containers (Bag on Valve [BOV] – 

Does not expel propellant with product.) The declaration of quantity shall disclose the net quantity 

of the commodity in terms of fluid measure.

After the recommendation, additional comments were accepted. An official was troubled with the wording “nonaerosol” and thought the intent of the proposal was to allow people to comparison shop between aerosols and nonaerosols. An official stated that the product could be measured by the liquid. A retired NIST, OWM employee 

questioned how it was measured. An official wanted to know whether the entire product was expelled when empty. 

An official stated that this was not ready for status as a Voting Item. The Committee met briefly and changed its 

recommendation. WWMA forwarded the item to NCWM, recommending it as a Developing Item. 

2011 NEWMA Interim Meeting: It was stated that testing for content could be problematic and that marking on the 

package should be net weight of product only, not including propellant, which is not part of product. The 

Committee believes there is better comparison of net contents of product being sold if words “NON-AEROSOL 

PRODUCT” are added to product label. NEWMA forwarded the item to NCWM recommending it as a Voting Item

with the following revision: add to the container language “A NON-AEROSOL PRODUCT.”

2011 SWMA Annual Meeting: Concern was expressed by an industry weights and measures consultant over an 

acceptable test procedure that would be used if volume was permitted. The NIST Technical Advisor noted that no 

specific language has been proposed and that the UPLR Section 6.4., Terms: Weight, Measures, Volume or Count 

declares that “any net content statement that does not permit price and quantity comparison is forbidden.” It was 

further noted that NIST Handbook 130, Section 10.3. Aerosols and Similar Pressurized Containers applies to 

aerosols and similar pressurized containers. One manufacturer has provided input to this proposal. The National 

Aerosol Association (NAA) has been contacted for input into this proposal. Preliminary comment by NAA is that 

BOV technology or versions of it has been around since the 1990s. The NAA Board of Directors member believes 

BOV technology is considered an aerosol, basing his opinion on a California Air Resources Board Regulation. The 

SWMA Committee requested that specific language be developed for this item and a complete response from the 

NAA. They also noted that test procedures will need to be discussed if a volume statement is to be considered. 

SWMA forwarded the item to NCWM recommending it as a Developing Item. 

2012 NCWM Interim Meeting: The Committee reviewed several letters from different manufacturers that use BOV 

technology recommending liquid volume as the appropriate method of sale for products in BOV style packaging. 

Concern was expressed that consumers would not be able to make value comparisons if similar items had different 

units of measure. 

Mr. Van Slyke (Lock Lord Bissell & Liddell LLP/Blue Magic, Inc.) provided a presentation indicating that they 

believe BOV does not fall under the aerosol guidelines. T he reasoning is that a B OV container does not expel 

propellant with the product; therefore, it inherently has less net weight. They believe that consumers do not have 

sufficient information to know differences between aerosols and BOV products. Mr. Van Slyke recommended two 

solutions amending the UPLR language as follows: 

10.3. Aerosols and Similar Pressurized Containers. – The declaration of quantity on an aerosol package and 

on a similar pressurized package shall disclose the net quantity of the commodity (including propellant), in 
L&R Committee 2013 Final Report

L&R - 17

terms of weight, that will be expelled when the instructions for use as shown on the container are followed, 

provided however that containers that separate propellant from the expelled product so that propellant is 

not expelled (such as containers using bag-on-valve technology) may be labeled either with weight or 

volume of the quantity of the commodity that will be expelled.

or

10.3. Aerosols and Similar Pressurized Containers. – The declaration of quantity on an aerosol package and 

on a s imilar pressurized package shall disclose the net quantity of the commodity (including propellant), in 

terms of weight, that will be expelled when the instructions for use as shown on the container are followed.

10.3.1 Containers that separate propellant from the expelled product so that the propellant is not 

expelled (such as containers using bag-on-valve technology) shall be prominently labeled NONAEROSOL. The declaration of quantity shall disclose the net quantity of the commodity in terms of 

fluid measure.

Mr. Douglas Raymond (National Aerosol Association [NAA]) gave a p resentation reporting the association’s 

position that a container using BOV technology is an aerosol, and its net quantity needs to be declared in terms of 

net weight. H e remarked that BOV has been around for twenty plus years and is not new to the marketplace. 

Various products are packaged using the BOV technology (e.g., sunscreen, wound washes, shaving cream, and car 

products). Different aerosol forms use liquid gas, compressed gases, and in barrier forms using Sepro, bladder, and 

BOV. Mr. Raymond also stated that BOV and non-BOV products are designed to expel their products equally. He 

stated that classifying a BOV container as a non-aerosol is misleading and a safety concern since this product is 

pressurized.

A regulatory official agreed that BOV containers should be labeled and tested by net weight. He remarked that test 

procedures need to be clarified for BOV containers. For example; should the bag be removed from the canister to 

recover the product?

Concern was also expressed that consumers would be confused if they encountered similar products with different 

unit pricing and if the products contents are labeled differently. The BOV proposal that was represented during the 

2012 NCWM Interim Meeting was based upon the views of the room air fresheners industry only. 

The Committee would like to have a better understanding of the variety and type of products in the marketplace and 

what is under current development. C larification is needed for the term “similar products” for example, what 

products meet this classification as defined in NIST Handbook 130, UPLR, Section 10.3. Aerosols and Similar 

Pressurized Containers. T he Committee is also requesting from NIST, OWM clarification on the definition of 

aerosol and a review for any updates to NIST Handbook 130, Interpretations and Guidelines, Section 2.2.7. Aerosol 

Packaged Products. The 2012 L&R Committee designated this as an Informational Item.

2012 NEWMA Annual Meeting: There was discussion about conflict between the declaration of content labels in 

the marketplace between aerosols and bag on valve (BOV) products. NEWMA recommended that the item remain 

as an Informational Item.

2012 CWMA Annual Meeting: A NIST Technical Advisor stated that the Food and Drug Administration (FDA) 

compliance department is reviewing to see if there is a conflict with their regulations. NIST has been in contact with 

the National Aerosol Association (NAA), and they will have a representative at the 2012 NCWM Annual Meeting.

The CWMA recommended that the item remain as an Informational Item.

2012 NCWM Annual Meeting: Mr. Douglas Raymond representing the National Aerosol Association (NAA) 

reported that the association is working with marketers, companies, and other trade associations; and NAA will 

provide an update on their position on this item at the 2013 NCWM Interim Meeting. The Committee received and 

reviewed five letters on this matter. 
L&R Committee 2013 Final Report

L&R - 18

2012 CWMA Interim Meeting: The NCWM L&R Committee Member from the CWMA provided an update. The 

Committee supported the work of the NAA to recommend consensus language for a definition of aerosol containers 

and a r ecommendation for BOV method of sale for the NCWM L&R to consider. CWMA was neutral and 

recommended that this be an Informational Item. 

2012 WWMA Annual Meeting: Industry and regulatory attendees agreed there are a variety of products sold with 

BOV packaging. Inspectors may have difficulty identifying and testing BOV items if they are not clearly marked 

and “BOV” on the label. The Committee is unsure on how BOV is defined and believes a test procedure may be 

needed for BOV packages if they do not follow NIST Handbook 130, UPLR Section 10.3. Aerosols and Similar 

Pressurized Containers. T he Committee would like to hear the updated position from NAA. WWMA 

recommended that this be an Informational Item.

2012 SWMA Annual Meeting: S WMA withheld comment until NAA presents proposed language with a 

recommendation at the 2013 NCWM Interim Meeting. SWMA recommended that the item be an Informational 

Item.

2012 NEWMA Interim Meeting: NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: The Committee received and reviewed several letters from BOV manufacturers. 

The letter from National Aerosol Association (NAA) contained draft language that proposes dual labeling for the 

method of sale on the product label. The Committee discussed that there is no applicable volumetric test procedure. 

It was stated that allowing two methods of sales is in opposition of the OIML TC 6 Committee on Prepackaged 

Products which resolved that aerosols should be declared by weight. The Committee was in agreement that if 

industry could develop a test procedure they would readdress the issue. T he Committee revised the item under 

consideration to include terminology to include “bag on valve.” T he Committee recommends this item be an 

Informational Item to allow time for manufacturers to provide feedback on the time frame for labeling to change 

over and to research a volumetric test procedure. 

2013 CWMA and NEWMA Annual Meetings: There was no additional information provided. Both regions are 

recommending this as an Informational Item.

Mr. Hank Pickens (Beaumont) provided a presentation at the 2013 N CWM Annual Meeting describing the 

procedures and reasoning for BOV to be labeled by volumetric measure. Mr. Pickens opposes NAA’s proposal for 

BOV to have a dual unit label. Douglas Raymond (National Aerosol Association [NAA]) is in support of a weight 

statement due to the challenge in testing this product. Mr. Raymond remarked that BOV products can be in liquid, 

paste, and powder form. A NIST Technical Advisor remarked that a volumetric method of sale would be in conflict 

with federal law regardless of whether it is an aerosol or not. Mr. David Sefcik (NIST, OWM) has agreed to host a 

meeting at NIST in Gaithersburg, Maryland, and bring interested federal agencies (i.e., FDA, FTC, and EPA) and 

stakeholders together. The Committee would like to see the outcome from this meeting that NIST will be hosting. 

Additional letters, presentations and data may have been part of the Committee’s consideration. To review the 

supporting documentation please refer to Appendix B in the Report of the 96th Annual NCWM Conference

[SP 1125, 2011], Appendix A in the Report of the 97th National Conference on Weights and Measures [SP 1160,

The gasoline gallon equivalent (GGE) unit was defined by NIST/NCWM in 1994 (refer to Appendix B in this 

report, Report of the 98th National Conference on Weights and Measures [2013]) to allow users of natural gas 

vehicles to readily compare costs and fuel economy of light-duty natural gas vehicles with equivalent gasoline 

powered vehicles. For the medium and heavy duty natural gas vehicles in widespread use today, there is a need to 

officially define a unit (already in widespread use) allowing a co mparison of cost and fuel economy with diesel 

powered vehicles. Also natural gas is sold as a vehicle fuel as either Compressed Natural Gas (CNG) or Liqufied 

Natural Gas (LNG) and each method of sale is measured in mass. Therefore, the generic term natural gas is 

proposed to be used in Handbooks 44 and 130 without the existing term "compressed." (The mathematics justifying 

the specific quantity (mass) of natural gas in a DLE and DGE is included in Appendix B, Report of the 98th National 

Conference on Weights and Measures [2013].) 

The official definition of a DLE and a DGE will likely provide justification for California, Wisconsin, and other 

states to permit retail sales of LNG for heavy-duty vehicles in these convenient units.

2012 CWMA Interim Meeting: A regulatory official commented that there is no standard for Diesel Gallon 

Equivalent (DGE), LNG and CNG are being sold in Wisconsin and other states as DGE in order to compete with 

diesel sales. As a r esult, a s tandard is urgently needed. DGE sales are occurring in the marketplace without a 

standard. The Committee recommended that FALS review the conversion factors for DGE and LGE for accuracy. 

CWMA supported this item and forwarded the item to NCWM recommending it as a Voting Item.

2012 WWMA Annual Meeting: The Committee worked in tandem with the S&T Committee since it had a related 

item. Ms. Kristin Macey (California) opposed the item because it would cause complications in the marketplace. 

The Committee believed the item had merit but would like to know whether the values accurately represent the 

actual value of various types of natural gas products. It acknowledged there are different compositions and sources; 

for example, LNG has a higher methane composition. Is there a possibility of additional conversion factors based 

on British Thermal Units (BTUs) from different sources? WWMA forwarded the item to NCWM recommending it 

as an Informational Item.

2012 SWMA Annual Meeting: An industry representative recommended the item be designated as Developing. A 

regulatory official questioned why industry is not installing the right equipment rather than putting a label on a 

nozzle. The Committee recommended that this item be reviewed by the FALS, in part to check the accuracy of the 

diesel conversion. The Committee also suggested that the 1994 standard for the gasoline gallon equivalent (GGE)

be reviewed. SWMA forwarded the item to NCWM, recommending it as an Informational Item.

2012 NEWMA Interim Meeting: NEWMA reviewed the CWMA comments. A General Motors representative 

indicated that there is a lot of discussion on a point of reference. There was comment that both methods of labeling 

may be required on a d ispenser. T he labeling issue may create more confusion for the consumer. NEWMA 

recommended review by the FALS. NEWMA forwarded the item to NCWM, recommending it as an Informational 

Item.

2013 NCWM Interim Meeting: A presentation in support of this item was given by Mr. Doug Horne (Clean Vehicle 

Education Foundation). Several comments were heard regarding the references and databases used to develop the

calculations. Concern was expressed with the conversion factors used. Concern was also expressed that the LNG 

method of sale should be by weight. A NIST, OWM S&T Technical Advisor recommends that L&R and S&T work 

in a joint session since there is a companion Item 337-1, NIST Handbook 44, Specifications, Tolerances and Other 

Technical Requirements for Weighing and Measuring Devices, Appendix D – Definitions: Diesel Liter and Diesel 

Gallon Equivalents (DLE, DGE), on the S&T agenda. A collaborative effort between the two Committees will 

ensure that the proposed equivalent unit is dispensed accurately at the dispenser. Several attendees spoke in support 

of the collaborative effort. T he Committee will request that the NCWM Board of Directors create a Steering 

Committee that consists of experts and stakeholders to review this proposal. L&R will prepare a list of comments 

that they would like the Steering Committee to review and address. T he L&R Committee recommends this as 

Informational Item. 

At the 2013 NCWM Annual Meeting the Committee was informed that the Natural Gas Steering Committee chaired 

by Mr. Mahesh Albuquerque would be reviewing this item.

Additional letters, presentations and data may have been part of the Committee’s consideration. Please refer to

or in bulk does not meet an active API service category as defined by the latest version of SAE 

J183, “Engine Oil Performance and Engine Service Classification (Other than “Energy 

Conserving”).” If a vehicle engine (motor) oil is identified as only meeting a vehicle or engine 

manufacturer standard, the labeling requirements in Section 2.33.1.4.1. Vehicle or Engine 

Manufacturer Standard apply. 

2.33.1.4.5. Tank Trucks or Rail Cars. – Tank trucks, rail cars, and other types of delivery 

trucks that are used to deliver vehicle engine (motor) oil are not required to display the SAE 

viscosity grade and service category or categories as long as the bill of lading or other 

documentation provides that information. 

All references to invoice or receipt will be enforceable effective on July 1, 2013.

(Added 2012) (Amended 20XX) 

Background/Discussion: 

The vast majority of engine oil used at professional fast lube facilities is the most current category of API (American 

Petroleum Institute) licensed oil. However, older, specialty, and some non-American vehicles take engine oil not 

listed as active under API’s private regulatory scheme; some are former API licensed oils now considered 

“obsolete” or “inactive” and some are simply licensed by another organization like the European Automobile 

Manufacturers Association (ACEA). However, if original equipment manufacturers (OEM) recommend those 

engine oils for their vehicles, consumers have a right to use them regardless of API’s blessing, and installers and 

retailers should be able to sell them without obstruction. 

Automotive Oil Change Association (AOCA) amendment is necessary because a cautionary statement appearing on 

service receipts without explanation will inappropriately mislead consumers with older and uncommon model 

vehicles into believing they shouldn’t use OEM-recommended engine oil. The average fast lube customer does not 

recognize API or SAE (Society of Automotive Engineers) to mean anything in particular but “CAUTION” and 

“OBSOLETE” in big capital letters could only be understood as negative. Scaring consumers in this way will not 
L&R Committee 2013 Final Report

L&R - 23

only push them to buy more expensive engine oil they do not need but also engender distrust in their installer service 

providers for recommending and/or using OEM-recommended engine oil.

The average age of cars in the current fleet is nearly 11-years old and it is not unusual for fast lubes to have 

customers with vehicles twice that age; for example, there are millions of opportunities for consumers to be misled 

into rejecting proper engine oil. The fact is American consumers are hanging onto their vehicles longer than API is 

hanging onto its service categories. When API designates a motor oil category as inactive, this does not mean 

consumers with vehicles designed to use that category turn in their cars or otherwise want to buy a more expensive 

grade of motor oil going forward. Therefore, a category of motor oil designed to work for particular makes and 

models of vehicles should not be burdened with the chilling effect of a ca utionary statement absent a specific 

clarification acknowledging the preeminence of the OEM’s recommendations.

The new standard phase-in factor must be considered as well. When API publishes a new edition of 1509, Engine 

Oil Licensing and Certification Systems, and/or creates a new service category, a reasonable phase-in period for bulk 

oil stock is necessary to accommodate older vehicle owners’ needs; for example, it may be in those customers’ best 

interests, both functionally and economically, to use motor oil developed in accordance with an earlier edition or 

service category so long as the automobile manufacturer originally recommended it, and its continued use has no 

impact on any remaining warranty coverage. Although it is common for API to retain a couple of the most recent 

service categories as “active,” API could choose to make all but the most recent service category “obsolete.” For 

fast lube operators to automatically upgrade bulk oil stock at API-determined intervals would be tantamount to 

giving API control over the price of oil change services regardless of what the market can bear. 

And what about packaged engine oil products already on the shelf or in the distribution chain when API makes a 

unilateral decision to deactivate an engine oil category? As a practical matter, tens of thousands of retailers and 

installers cannot re-mark millions of packages to coincide with API’s timing or take the financial hit for sending it 

all back in violation of purchase agreements. Attempting to enforce the labeling requirement at this level would be a 

nightmare for everyone involved. The way to avoid this problem is to adopt AOCA’s amendment so that the 

requirement for proper labeling of packaged containers of engine oil rest with the party in control of the packaging – 

the manufacturers. 

Without the amendment, the labeling requirement will be very difficult to enforce given the inventory of packaged 

goods remaining after an active engine oil category has been declared inactive or obsolete.

Fast lubes would experience catastrophic business loss if customers with older and uncommon model vehicles were 

alienated. Maintenance costs for consumers with older model cars could easily double if they are confused into 

believing they need the latest category of engine oil.

AOCA contends that the proposed amendment will accomplish three important goals: 1) prevent unintended 

consumer confusion and product stigma from using a cautionary statement by reestablishing the connection to OEM 

recommendations; 2) provide the necessary exemption to protect retailers and installers for selling lawful packaged 

inventory; and 3) which leads to an increase in practical enforcement prospects. 

The most analogous regulatory situation to the one at issue in AOCA’s proposed amendment is found in the Federal 

Trade Commissions (FTC) Test Procedures and Labeling Standards for Recycled Oil (16 CFR 311). In that 

rulemaking process, FTC specifically rejected requiring recycled engine oil to be labeled “recycled” because of the 

stigma associated with the term at that time (see 72 FR 14410 – 14413 & FN11 [1 H.R. Rep. No. 96–1415, 96th

Cong. 2d Sess. 6 (1980), reproduced at 1980 U.S. Code Cong. & Ad. News 4354, 4356. ‘‘Oil should be labeled on 

the basis of performance characteristics and fitness for its intended use, and not on the basis of the origin of the 

oil.’’]). The National Automobile Dealers Association (NADA) also commented in favor of this approach: “NADA 

further stated that by not requiring that ‘‘substantially equivalent’’ recycled oils be labeled ‘‘recycled’’ or ‘‘rerefined,’’ used oil processors are able to market their products effectively.” (72 FR at 14411) No “recycled” or other 

potentially derogatory designation is required so long as the finished product meets the appropriate API standard.

2012 CWMA Interim Meeting: AOCA stated that the oil change industry is small businesses without legal staff so 

they need clear guidance that is easily understood. These businesses follow the OEM recommendations, which 

recommend oils that do n ot follow API or SAE standards. The language should acknowledge that some 
L&R Committee 2013 Final Report

L&R - 24

manufacturers approve and recommend their own oil (i.e., General Motors [GM] and Audi-Volkswagen). AOCA 

thought that the current language required all OEM oils that did not meet a specific API performance standard to be 

labeled as obsolete. A GM representative confirmed that GM produces their own oil, Dexos (the best oil for any 

car), which does not have an API certification. A FALS member shared the API motor oil guide, (refer to 

Appendix C of this report) which labels specific categories of oil as obsolete. If a manufacturer does not label the 

oil with an API obsolete category, the product is not considered to be obsolete. OEM manufacturers that were 

named do not label their oil with an obsolete category, and so oil changers do not need to worry about the obsolete 

label being used on OEM motor oils. AOCA asked if there would be a grace period to sell product purchased prior 

to January 2013. States regulators clarified that nothing is written in the regulation, and grace periods would be 

determined on a state by state basis. AOCA reiterated that the language should clearly state that OEM oils that do 

not have API certification are not obsolete. She asked that the Committee recommend this clarifying language. 

AOCA also stated that installers should not be responsible for labeling on packaged products received. A regulatory 

official stated that retailers in other industries are responsible for labeling on packages received, and it would be an 

unfair market advantage to allow some retailers to use products that were illegally labeled. Since the current 

language is not clear about exactly what oils are obsolete, the Committee recommended that FALS make a 

recommendation at the NCWM Interim Meeting. CWMA forwarded the item to the NCWM recommending it as a 

Voting Item with the stipulation that FALS develop the language. 

2013 CWMA Annual Meeting: Mr. Kevin Ferrick (API) opposed the proposed language for this item; stating if a 

product meets an obsolete standard the customer deserves to know this. C WMA would like to see additional 

information from the FALS.

2012 WWMA Annual Meeting: M s. Kristin Macey (California) opposed the item because it removes retailer 

accountability. Mr. Ferrick who opposed the additional language also provided a presentation and written comments 

for the WWMA. Mr. Kurt Floren (Los Angeles County, California) also opposed the item for reasons stated by 

Ms. Macey. WWMA did not forward the item to NCWM.

2012 SWMA Annual Meeting: An API Representative voiced API’s opposition to the item and provided the written 

testimony in dispute of the comments and claims made by the submitter (refer to Appendix C, in this Report of the 

98th National Conference on Weights and Measures [2013]).

2012 NEWMA Interim Meeting: API stated it opposes the item and that specifics have been submitted in writing. 

API suggested this proposal and Item 237-4 be Withdrawn. General Motors indicated the proposal appears to allow 

older formulations of engine oil, but newer formulations give better performance, even in older vehicles. G M 

prefers current formulation of engine oil. NEWMA did not forward the item to NCWM. 

2013 NEWMA Annual Meeting: Mr. Ferrick indicated that API submitted comments regarding their opposition to 

this item and requested that this item be Withdrawn. NEWMA would like to see additional information from FALS.

2013 NCWM Interim Meeting: A state opposed this item and would like to see it Withdrawn. The FALS Chairman 

remarked that there are several engine oils designed for specific model vehicles, and FALS is trying to resolve this 

issue. A Committee member remarked that a statement of accountability should be within the language. T he 

Committee would like to see additional language developed by FALS and made this an Informational Item. 

2013 NCWM Annual Meeting: The FALS submitted modified language for Sections 2.33.1.4. Engine Service 

Category, 2.33.1.4.1. Vehicle or Engine Manufacturer Standard, and 2.33.1.4.12. Inactive or Obsolete Service 

Categories. The Committee would like to have regional input on this modified language to review at the 2014 

NCWM Interim Meeting.

(Added 2012) (Amended 2013)

Background/Discussion: 

There is a chain of engine oil purchasers involved in the sale of bulk engine oil, all of whom need accurate and 

adequate information about the commodity so that they can make price and quantity comparisons. The engine oil 

distributor is a purchaser with respect to engine oil manufacturers, the installer is a purchaser with respect to engine 

oil distributors, and the consumer is a purchaser with respect to installers. Installers like fast lube operators can only 

provide accurate and adequate information about bulk engine oil to consumers if their distributors provide it at the 

point of delivery. It would be manifestly unfair to expect installers to legally vouch in writing for the quality of 

distributors’ engine oil products absent a corresponding written verification requirement.

The original language for consideration (refer to the Report of the 97th National Conference on Weights and 

Measures [SP 1160, 2012], L&R Committee Report) creating a Method of Sale, Section 2.33.1.4.2. Tank Trucks or 

Rail Cars and Engine Fuels and Automotive Lubricants Regulation Section and 3.13.1.4.2. Tanks Trucks or Rail 

Cars inadvertently created a loophole for distributors to avoid providing necessary product documentation at the 

time of delivery. 

Whether or not NCWM waives tank truck labeling is not the issue. The problem lies in the controversy this 

provision allows. If a distributor displays the SAE viscosity grade and service category on a tank truck, then he/she 

does not have to provide a bill of lading. This poses a serious risk to installers, like fast lubes, because the 

regulation requires them to vouch for viscosity grade, service category, and brand on customer receipts but doesn’t 

guarantee the installers will receive that same information in writing from their distributors – the parties with actual 

control over product quality/identity. 

There is no practical way for fast lubes or NCWM to enforce this “either/or” regulatory scenario. If a distributor 

arrives at an installer’s facility without documentation, how can the installer hold the distributor to it under NIST 

Handbook 130? The distributor can simply claim his/her truck is adequately marked. Installers are not professional 

truck inspectors; they cannot be expected to act as enforcement agents in this scenario. Meanwhile, in order for 

local weights and measures officials to hold a distributor accountable, they would have to arrive on the scene at the 

time of delivery, which coincidence is unlikely at best. Any subsequent official inquiry would take place after the 

distributor has had the opportunity to subsequently mark any unmarked truck at issue. Moreover, risk of distributor 

failure in providing necessary documentation is high because most do not and never have been willing to provide 

bills of lading or other documentation to fast lubes at the time of delivery. Additionally, the imperative for any 

installer labeling and/or receipt information requirements to be matched by corresponding requirements for engine 

oil distributors includes “brand.” Installers cannot purport to verify via any form of documentation information that 

distributors have not documented at delivery. Handbook 130 (2013), Uniform Method of Sale, Section 2.33. Oil and 

Uniform Engine Fuels and Automotive Lubricants Regulation and Section 3.13. Oil required installers to verify 

brand in writing and; therefore, distributors should be required to verify it too. For NCWM to require otherwise 

would be manifestly unfair to installers by subjecting them to liability for the bad acts of distributors without any 

paperwork trail to rely upon in their own defense.

No one has more at stake than installers. Should a product quality problem occur with packaged goods, it is

relatively easy to trace the goods back to the manufacturer. However, this is not the case with motor oil transported 

in bulk; it all looks alike; it may have “changed hands” numerous times before reaching the fast lube facility, and 

even with testing can be impossible for a fast lube to verify because oil companies use chemical markers that only 

they can identify. Since motor oil specifications have become so precise, and so expensive, fast lube operators stand 

to lose thousands of dollars every time a distributor delivers a lesser product. 

Moreover, when a distributor delivers the wrong product, it is the fast lube operator who gets stuck holding the bag 

for consumer claims, which can be excessive if the “wrong” product did or could cause engine damage. It takes

weeks before a bad load is detected, which by then anywhere from 500 to 700 customers have been serviced. What 

is the remedy? All of the customers must be called back and re-serviced for free before any damage has the 

opportunity to occur. Requiring distributors to provide the same documentation required of installers represents the 
L&R Committee 2013 Final Report

L&R - 27

minimum necessary step to at least protect installers from misrepresentation claims when a d istributor 

“mis-delivers” bulk oil.

API and Independent Lubricant Manufacturers Association (ILMA) have been publicly quoted as supporting the 

requirement that distributors provide documentation at delivery as if the new paragraphs at issue already mandate it 

under all circumstances. See Lube Report (August 1, 2012) www.imakenews.com/lng/e_article002489327.cfm?x=b11,0,w. 

The Environmental Protection Agency’s (EPA) Federal Used Oil Management Standards require detailed 

transporter chain of custody documentation (40 CFR Part 279). See also EPA’s Chain-of-Custody Procedures for 

Samples and Data (www.epa.gov/apti/coc/), which makes clear that failure to maintain a proper chain of custody 

regarding samples and/or data will destroy any ability to defend oneself if challenged.

According to the USDA, segregation and documentation for specialty (bulk) crops continue from the elevator to the 

final producer or consumer. (Traceability in the U.S. Food Supply: Economic Theory and Industry Studies [USDA 

Economic Research Service 2004]).

Under the Food and Drug Administration (FDA) Food Modernization Act (Public Law 111-353, 

www.gpo.gov/fdsys/pkg/PLAW-111publ353/pdf/PLAW-111publ353.pdf), documenting the production and 

distribution chain of food products is required so that “in case of a problem, a product can be traced back to the 

source.”

The Department of Transportation (DOT) overlaps with EPA regarding the Federal Hazardous Waste Manifest 

System (40 CFR Part 262, www.ecfr.gov/cgi-bin/text-idx?tpl=/ecfrbrowse/Title40/40cfr262_main_02.tpl), which 

mandates detailed documentation of hazardous waste from cradle to grave; for example, from generator to 

transporter to end user/disposal.

2012 CWMA Interim Meeting: The Automotive Oil Change Association (AOCA) stated that the current language 

would allow the distributor to either label the truck or tank car or the bill of lading. The language should clearly

state that distributor needs to provide the retailer with a bill of lading or other documentation that includes product 

identity information. A FALS member acknowledged the current language could be construed to say that the 

distributor does not need to provide this documentation, and that was not the intent. The Committee recommends 

that FALS provide concise language that states that a bill of lading or other documentation with appropriate product 

information must be provided to the retailer. FALS should submit proposed language to the NCWM L&R

the Committee. Mr. Ferrick remarked that the submitted proposal was rather wordy, however; he does not disagree 

with the language. Ms. Kristin Macey (California) supported the submitted proposal. The Committee agreed that 

the submitted proposal is too lengthy and presented alternative language for consideration. The Committee regretted 

that the submitter was not present to answer questions and concerns. W WMA forwarded the item to NCWM 

recommending it as an Informational Item as modified and presented below: 

2.33.1.5. Tank Trucks or Rail Cars. – Tank trucks, rail cars, and other types of delivery trucks that are used 

to deliver vehicle engine (motor) oil are not required to display the SAE viscosity grade and service category or 

categories; however, as long as the bill of lading or other documentation shall provides that information. 

2012 SWMA Annual Meeting: An API representative stated the proposal is consistent with API goals for distributer 

and installers to disclose what they are installing. The Committee agreed that adequate documentation should be 

provided. SWMA forwarded the item to NCWM recommending it as a Voting Item.

2013 NCWM Interim Meeting: Mr. Ron Hayes, FALS Chairperson remarked that FALS is recommending language 

changes for this item. FALS developed Section 2.33.1.6. Documentation, which resolves the issues bought before 

the Subcommittee. FALS recommended to the Committee that the revised language move forward as a Voting Item. 

The Committee concurs with the language revisions and proposed this item be a Voting Item. 

2013 NEWMA and CWMA Annual Meetings: Both Associations supported this as a Voting Item. During the open 

hearings at the 2013 NCWM Annual Meeting, the FALS Chair proposed this item move forward as a Voting Item.

232-4 V Section 2.XX. Printer Ink and Toner Cartridges Labeling

(The Committee returned this item to Informational Status.)

Source: 

Southern Weights and Measures Association (2010)

Purpose: 

Clarify the labeling requirements for industry, consumers and weights and measures officials. 

Item Under Consideration: 

Amend NIST Handbook 130, Method of Sale Regulation as follows:

2.XX. Printer Ink and Toner Cartridges Labeling.

2.XX.1. Definitions.

(a) 2.XX.1.1. Printer Ink Cartridges. – Any cartridge or module that contains ink or a similar 

substance in liquid form employed in the printing and/or copying of documents, papers, 

pictures, etc., that is used in a printing device and designed to be replaced when no longer 

able to supply its contents in printing and/or copying. 

(b) 2.XX.1.2. Toner Cartridges. – Any cartridge or module that contains toner, powder, or 

similar non-liquid substance employed in the copying or printing of documents, papers, 

pictures, etc. that is used in a printing and/or copying device and designed to be replaced 

when no longer able to supply its contents in printing and/or copying.

2.XX.2. Method of Sale and Labeling.
L&R Committee 2013 Final Report

L&R - 29

(a) 2.XX.2.1. Method of sale, printer ink cartridges. – All printer ink cartridges kept, offered, or 

exposed for sale or sold shall be sold in terms of the count. 

(b) 2.XX.2.2. Method of Sale, toner cartridges. – All toner cartridges kept, offered, or exposed 

for sale or sold shall be sold in terms of the count. 

2.XX.3. Yield Disclosure – If the seller discloses the yield of printer ink or toner cartridges on the 

package, then it shall be measured using the latest version of ISO/IEC printer yield standard on the 

package offered for prepackaged sale. This information shall be considered a supplemental 

statement.

Note: Labeling shall be enforceable after month/day/20XX.

(Added 20XX)

Background/Discussion: 

Over the past several years, there has been a change in the marketplace on inkjet and toner cartridges net content 

statements. There is little uniformity, and the Committee has seen some labels with a net content or with only a 

page yield count (e.g., prints 1000 pages). The NIST, OWM pointed out that, according to guidelines printed in 

NIST Handbook 130, Weights and Measures Law, Section 19. Information Required on Packages, these products 

are required to have the net contents of the ink (and toner) labeled, but manufacturers have resisted, claiming an 

exemption under the FPLA. The purpose of this proposal is to specifically clarify the requirements for industry, 

consumers, and weights and measures officials. 

2009 SWMA Annual Meeting: A Lexmark representative commented that they do not believe that a net content 

statement should be required, and that a page yield is sufficient. He read the main points of a letter from Lexmark to 

Mr. Gray (Florida Department of Agriculture and Consumer Services) dated March 17, 2009. T he main points 

within the letter were: 1) the ink associated with a cartridge is a small fraction of the total cost of the print cartridge 

mechanism; 2) a page yield can provide a meaningful comparison to a consumer if all manufacturers employ the 

same estimating assumptions and techniques; and 3) International Organization for Standardization (ISO) studied 

this issue for years and has rejected reliance on ink volume or quantity; instead ISO has developed a yield estimating 

and claiming methodology that permits cartridges to be compared using a consistent yardstick. Unlike ink volume 

measurements, page yield measurements provide a consumer with a reliable way to compare the amount of printing 

that can be expected. Lexmark also stated that ink is expressly exempt from labeling as provided by the FPLA, 

16 CFR Part 503.2(a).

An industry representative said this issue does need to be discussed and reviewed further. However, many officials 

believe that consumers should know what they are getting. I f it is determined that page count is the quantity 

statement, then the page print standard should be reviewed and have tighter standards. Mr. Gray said that more data 

is needed from manufacturers on this issue. SWMA forwarded the item to NCWM, recommending it as a 

Developing Item. 

2010 NCWM Interim Meeting: Mr. Matthew Barkley (Hewlett Packard Co.) commented that the FPLA creates an 

exemption for ink which extends to toner and ink cartridges. A declaration of weight and volume are not the best 

way for consumers to make value comparisons. Customers benefit from page count/yield. Mr. Barkley urged that 

this issue be Withdrawn. If this issue is to proceed, it should be Informational to allow for a review of the FPLA 

exemption. He suggested that page yield is widely accepted and has repeatability measures. 

Mr. Jeran (Hewlett Packard Co.) submitted a white paper from the Information Technology Industry Council (refer 

to the Report of the 96th National Conference on Weights and Measures [SP 1125, 2011], Appendix C). This white 

paper included manufacturers from Epson, Hewlett Packard, Kodak, and Lexmark. Mr. Jeran explained that his 

background is with ink and toner measurement. For the same volume of ink, two different systems of the same 

model cartridge from two different vendors can print a different number of pages. In order to determine the page 

yield, they are using the ISO/IEC methodology. ISO is working on a photo yield standard.

An official expressed concerns with page yield being the standard page print for quantity. Variation exists based on 

the type of cartridge, printer, and font and if graphics/photos are being printed. There is also a concern with what 
L&R Committee 2013 Final Report

L&R - 30

ink cartridge refillers are doing. The Florida official reviewed the current practice of refillers, and said they are 

stating the amount of ink on labels. T here are many manufactured packages in the marketplace, so value 

comparison to the Original Equipment Manufacturer (OEM) is critical. This is an expensive commodity and 

clarifications of the requirements are needed. An official recommended that this item not be Withdrawn, but made 

Informational to allow time for research. Regulatory officials firmly believe that there needs to be a consistency 

with the declaration statement on these types of items. A consumer stated that the net content needs to be stated 

with voluntary supplemental information for page yield. Some voiced their opinion that consumers need to know 

page yield in order to make a value comparison. The NIST Technical Advisor stated that under the FTC regulations 

ink and toner cartridges were not part of the CFR. NIST, OWM met with the FTC on February 26, 2010, to request 

clarification of the exemption. According to the Committee, there needs to be a test procedure for verification of net 

content developed for ink and toner cartridges. The 2010 L&R Committee designated this item as an Informational 

Item until they receive clarification from FTC, review ISO standards, and determine what refillers’ current practices 

are.

2010 NEWMA and CWMA Annual Meetings: Both associations received a p resentation from Mr. Pociask

(American Consumer Institute) regarding a lack of consumer information when purchasing computer printers and 

cartridges. Both associations expressed that there are still many unanswered questions and would like to hear from 

manufacturers of printer ink and toner cartridges. Both associations recommended that the item remain as an

Informational Item.

2010 NCWM Annual Meeting: Mr. Pociask presented a 2007 study done by his organization with funding by a 

telemarketing research company. An official expressed concern that the presentation was not clear, and asked if 

page count is based on certain fills levels or declaring the weight on the cartridge itself. Mr. Pociask responded that 

Quality Logic uses the ISO standards. He concluded that net weight is easy to enforce. Mr. Pociask stressed that his 

focus is to provide information that gives consumers useful information in purchasing printers and the life cost of 

the printer, including printer ink cost.

Another official stated that the study was interesting but would like to hear from manufacturers. There are several 

issues; cartridges are only for specific printers, when comparing price per page you suggest that price is static, and 

printer ink cartridge refillers need to be addressed. 

Mr. Rosenberg (Information Technology Industry Council) agreed that providing consumers with information is 

meaningful; however; relevant to the consumer is the number of pages that can print. The ISO standards are a good 

tool, but will lead to customer confusion. Mr. Rosenberg said that much more discussion is necessary on this issue

(refer to the Report of the 96th National Conference on Weights and Measures [SP 1125, 2011], Appendix C). 

2010 NCWM Annual Meeting: The Board of Directors established a Printer Ink and Toner Cartridge Task Group to 

review and obtain additional information from all stakeholders. Ms. Dempsey (Montgomery County Weights and 

Measures, Ohio) was appointed as chair and Ms. Warfield was designated as the NIST Technical Advisor. 

2010 CWMA Interim Meeting: Ms. Dempsey, Chair, Printer Ink and Toner Cartridge Task Group on announced 

her resignation to the association. Ms. Dempsey gave a briefing on this issue, in particular whether this particular 

form of ink is included in the exemption of the FPLA. I t was indicated that Federal Trade Commission (FTC) 

believes this exemption only applies to ink in pens, not in printer cartridges. Regulators commented that “yield’ is 

more important for cost comparison for consumers; however, other regulators believed that “yield” is not a weights 

and measures issue. Another concern was that the ISO yields are based upon approximations. Discussion also 

included whether regulators would have to purchase printers in order to verify yield. It was generally agreed that 

this is a v ery complicated matter, and the method of sale needs to be measurable. A n official said he asked a 

manufacturer how the packages are filled. The response indicated that packages are filled by volume. The CWMA 

Committee supported the efforts of the Printer Ink and Toner Cartridge Task Group to gather more information for 

development of this proposal. CWMA recommended that the item remain as an Informational Item. 

2010 WWMA Annual Meeting and the 2010 NEWMA Interim Meeting: It was announced that NCWM is seeking a 

chair for the Printer Ink and Toner Cartridge Task Group. WWMA recommended that the item remain as an 

Information Item.
L&R Committee 2013 Final Report

L&R - 31

2010 SWMA Annual Meeting: It was announced that a chair is needed for the Printer Ink and Toner Cartridge Task 

Group. The Committee did not endorse the formation of the Printer Ink and Toner Cartridge Task Group to resolve 

this issue. Only within the past couple years have manufacturers changed their declaration statement to read “yield.” 

Allowing the declaration by yield will open the door for other commodities to change their labeling (e.g., loads of 

laundry). The SWMA Committee recommended that these commodities be sold by volume and weight; however, 

they are not opposed to yield being a supplementary statement. T his will allow for inspectors to verify the net 

contents, and also provide information for consumers to make value comparisons. The Committee would like to 

seek additional information from industry and ink refillers. SWMA recommended that the item be a Voting Item. 

2011 NCWM Interim Meeting: The Printer Ink and Toner Cartridge Task Group held its first work session, chaired 

by Ms. Maureen Henzler (Kansas Department of Agriculture). There was discussion on the current forms and types

of printer ink. Industry also explained that they are able to deliver less ink with a better print quality. As a result 

they refrain from using the net content statement but believe that a page yield is more useful information for a 

consumer in making comparisons. Industry was informed that yield is not acceptable and they cannot use words like 

“approximate” and “estimated.” It was agreed that yield could be a supplementary statement on the package. The 

2011 L&R Committee designated this item as an Informational Item. 

The Printer Ink and Toner Cartridge Task Group requested the following additional information from industry: 

1. How does the ISO standard work and how does this standard would fit into the weights and measures test 

procedure? 

2. How is print darkness measured? 

3. Why have manufacturers removed the net weight declaration from packages and replaced it with a page 

yield? 

4. When changing formulas, is the toner receptacle resubmitted back through the ISO standards to validate the 

page print accuracy? 

2011 NEWMA Annual Meeting: There were no comments heard on this item. The Committee Chair reminded 

members that the Printer Ink and Toner Cartridge Task Group will be meeting on the Sunday prior to the start of the 

NCWM Annual Meeting, and that industry will be giving a p resentation. T he NEWMA L&R Committee

recommended that this item move forward as an Informational Item.

2011 CWMA Annual Meeting: There were several comments heard on this item. Concern was expressed that ink 

cartridges used to have quantity on the label, but now, in the marketplace, only yield is used for labeling. A state 

director expressed concern that ink refillers are not being addressed under this proposal. T he CWMA L&R 

Committee recommended that this item move forward as an Informational Item.

2011 NCWM Annual Meeting: T he Printer Ink and Toner Cartridge Task Group held a Sunday work session. 

Several state, county, and city weights and measures officials and members of industry attended. 

Mr. Josh Rosenberg (Information Technology Industry Council [ITI]), and other printer industry representatives 

gave a p resentation outlining why they believe yield is the appropriate method of sale for their products. T hey 

responded to questions regarding the quantity control they have when manufacturing the cartridges. All industry 

representatives acknowledged in response to questions that their companies have very good quantity control systems 

in place for filling cartridges. A stakeholder stated that packages must have the weight, measure, or count; no other 

type of labeling is acceptable. Participants commented that “yield” is not an acceptable means of labeling for any 

product. T he Printer Ink and Toner Cartridge Task Group agreed to meet again at the 2012 NCWM Interim 

Meeting. The group requested that industry representatives make another presentation at that time that would be 

limited just to the labeling issue. The Printer Ink and Toner Cartridge Task Group plans to submit a method of sale 

proposal to the NCWM L&R Committee for a method of sale for packaged printer ink and toner cartridges.

During the Committee open hearings, Mr. Rosenberg (representing Lexmark, HP, Kodak, Epson and Brother), 

submitted the industry presentation from the Sunday session for the record (refer to Appendix C in the Report of the 
L&R Committee 2013 Final Report

L&R - 32

96th National Conference on Weights and Measures [SP 1125, 2011]). Mr. Rosenberg remarked that quantity 

declarations by volume or weight do not meet the objectives of his organization nor consumers’ preference. He said 

that yield is the best way to enable consumers to make informed purchase decisions. He believes the ISO standard 

for yield can be applied to create that data. Mr. Rosenberg stated that industry representatives will attend upcoming 

regional meetings to address any issues or concerns. A stakeholder noted that he does not believe the ISO yield 

standard is acceptable, because each manufacturer’s default system is different. He also pointed out that NCWM is 

not a performance based evaluation agency, and encouraged the Task Group to propose the use of weight or volume 

as the method of sale. The L&R Committee requested that the Printer Ink and Toner Cartridge Task Group continue 

developing this item. 

2011 CWMA Interim Meeting: An official supported the item and asked the Committee to forward it as a Voting 

Item. Two other officials would rather see a weight statement because the amount of ink would be too small to 

measure the density. An official opposing a weight statement and supporting measuring by yield stated that one

cannot measure when the cartridge retains some portion of ink and measuring by volume does not help inform the 

consumer. An official questioned how yield could be measured. S everal officials stated that yield could be a 

supplemental declaration and lawsuits could deal with issues related to yield. NCWM may want to consider having 

the products labeled by weight and not volume. In addition, supplemental information such as yield may be 

displayed, but not in the net weight area. CWMA recommended that the item remain as an Informational Item. 

2011 WWMA Annual Meeting: A consumer stated that no comments have been heard and, therefore, the item is 

ready to move forward for a vote. An official did not believe that this item was ready to move forward as a Voting 

Item because of the lack of testing procedure and a recommendation from the Printer Ink and Toner Cartridge Task 

Group. He then made a motion that this item be made Informational; this motion did not receive a second motion. 

In a split vote WWMA recommended that the item be a Voting Item. 

2011 NEWMA Interim Meeting: No comments were recorded. NEWMA recommended that the item remain as an 

Informational Item. 

2011 SWMA Annual Meeting: N o comments were recorded. The Committee supported the item as written. 

SWMA recommended that the item be a Voting Item. 

2012 NCWM Interim Meeting: Ms. Henzler informed the Committee that the Task Group did not have a 

recommendation on a method of sale for either the ink or toner. They did suggest minor editorial changes to add the 

word “copying” after the word “printing” or vice versa, throughout the definitions.

Several members of the ink and toner industry recommended that this item be Withdrawn and they have reflected 

this in letters written to the Committee since this item first appeared. They remarked that the current proposal would 

confuse and mislead consumers. They believe that consumers are not concerned with the net quantity of ink they 

are getting, but how many pages they can print. They agreed that the definitions do need additional work. They 

added that there are other ink technologies in the marketplace such as, wax sticks and oils. Currently wax 

sticks/crayons are sold by count. 

A contractor commented that the Method of Sale Regulation states that items must be sold on the basis of weight, 

measure, or count. T he regulation should be the starting point with the possibility of adding supplementary 

information. An industry representative commented that they had submitted previous background and 

documentation on this item. They will continue to work with the Printer Ink and Toner Cartridge Gravimetric 

Package Testing Task Group. 

The Committee believes test procedures need to be developed to test these commodities. In addition, destructive 

testing of these products can be costly. The Committee wants to look at the possibility for both toner and ink to be 

sold by weight. Ms. Cardin will request that the NCWM Board of Directors appoint a new work group to develop 

test procedures and to disband the current Task Group on Printer Ink and Toner Cartridges. The 2012 L&R 

Committee designated this item as an Informational Item. 
L&R Committee 2013 Final Report

2012 NEWMA Annual Meeting: Mr. Floren (Los Angeles County, California) indicated that there is an impasse on 

Method of Sale and test procedures on these items. The work group is not planning to meet at this time to resolve 

the issues. NEWMA recommended that the item remain as an Informational Item.

2012 CWMA Annual Meeting: Ms. Cardin gave an overview of this item and provided an update. The Task Group 

has been formed to focus on test procedures for weight statements on ink and toner cartridges. A n industry 

representative remarked he was supportive of the Task Group’s efforts and that an acceptable method of sale would 

be reached. He also recommended that the Conference get further participation from industry and stakeholders. The 

Committee recommends that this item be Information. 

2012 NCWM Annual Meeting: The new Printer Ink and Toner Cartridge Gravimetric Package Testing Task Group

met to discuss a test method that would require industry to label cartridges with a tare (packaged materials) weight. 

This Task Group, chaired by Ms. Cardin, will continue developing gravimetric test methods for printer ink and toner 

cartridges, and will provide a report at the 2013 NCWM Interim Meeting. The Committee is placing an item in the 

260 Series (NIST Handbook 133) of the next agenda to report the work of the Printer Ink and Toner Cartridge

Gravimetric Package Testing Task Group. The L&R Committee will delay further development of this Method of 

Sale item until the Task Group has completed its recommendations. 

2012 CWMA Interim Meeting: The NCWM L&R Committee from the CWMA reported that the Printer Ink and 

Toner Cartridge Gravimetric Package Testing Task Group is developing test methods for printer ink and toner. 

CWMA is neutral and recommended that the item remain as an Informational Item. 

2012 WWMA Annual Meeting: The Committee noted that the NCWM L&R Committee will not develop this item 

further until it receives recommendations for gravimetric testing from the Printer Ink and Toner Cartridge

Gravimetric Package Testing Task Group. WWMA recommended that the item be Withdrawn.

2012 SWMA Annual Meeting: A n industry representative serving on the Printer Ink and Toner Cartridge 

Gravimetric Package Testing Task Group commented that it is a new group established to develop a test procedure 

for checking net contents without regard for the method of sale. SWMA supported the Method of Sale proposal as 

written recommended that the item be a Voting Item.

2012 NEWMA Interim Meeting: NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: Judy Cardin (Printer Ink and Toner Cartridge Gravimetric Package Testing Task 

Group Chair) provided a presentation on the work of the task group (refer to Item 260-3). Ms. Cardin also provided 

a marketplace survey that reflected “count” was the most common quantity statement being used. Industry was 

asked about the feasibility of placing the tare weight on cartridges. Their response was that it was not practicable 

due to cartridge parts being manufactured domestically and internationally and may not always be made of the same 

material. The presentation also reflected an in-house test using a gravimetric procedure. The Task Group concluded 

that there is not a practical test procedure and the work group is disbanding. The Committee discussed the results of 

the task group and reviewed the method of sale language. In conclusion the method of sale language was revised by 

the L&R Committee to allow for this product to be sold by count. Ms. Lisa Warfield (NIST, OWM) commented 

that consideration needs to be given to the time manufacturers will need to change over their labeling. The L&R 

Committee recommended this as a Voting Item.

NEWMA had several representatives that believed “count” was meaningless. A remark was made about “low 

count” being exempt from count requirements. N IST responded that it would be exempt if written into the 

requirements. The Federal Trade Commission (FTC) was consulted but did not take a position on the issue. Several 

attendees speaking as consumers voiced concerns on a yield statement. NIST advised that there are ISO/IEC yield 

standards. NEWMA recommends the modification to Section XX.2. Method of Sale. 

2.XX.2. Method of Sale and Labeling. 

2.XX.2.1. Method of sale, printer ink cartridges. – All printer ink cartridges kept, offered, or exposed 

for sale or sold shall be sold in terms of the count 
L&R Committee 2013 Final Report

L&R - 34

2.XX.2.2. Method of Sale, toner cartridges. – All toner cartridges kept, offered, or exposed for sale or 

sold shall be sold in terms of the count 

2.XX.3. Yield Disclosure. – The seller shall disclose the yield of printer ink or toner cartridges as per 

ISO/IEC 19752, ISO/IEC 19798, ISO/IEC 24711, ISO/IEC 24712 on the package offered for prepackaged 

sale, or on the receipt for direct sale, or on the transfer document for bulk sale. 

All work has been completed and industry and NCWM L&R are in agreement on the Method of Sale by Count. The 

proposed modification provides clarity to the consumer when “yield” is questioned. NEWMA recommends the 

modified language move forward as a Voting Item. 

CWMA reviewed the modified language from NEWMA and agrees that count alone is not sufficient and that yield 

should be considered since it appears to be the best option and solution. It was agreed that weight is the correct 

solution if a test method could be determined. CWMA recommends that a yield be required and disclosed on the 

principal display panel of the package, on the receipt for direct sale, or on t he transfer document for bulk sale. 

CWMA recommends with these changes it be a Voting Item.

During the 2013 NCWM Annual Meeting the Committee heard several comments that there may not be a feasible 

way to label and test this product. Industry believes that consumers are interested in a yield statement when making 

a purchase. The Committee modified the language in Section 2.XX.3. Yield Disclosure to read as:

2.XX.3. Yield Disclosure. – If the seller discloses the yield of printer ink or toner cartridges on the package, 

then it shall be measured using the latest version of ISO/IEC printer yield standard on the package offered 

for prepackaged sale. This information shall be considered a supplemental statement.

The Committee moved this item to an Informational for a review of the amended language at the Fall Regional 

Association Meetings.

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to 

Appendix C in the Report of the 97th National Conference on Weights and Measures (SP 1160, 2012) to review

these documents.

(Added 2013)

Background/Discussion: 

Significant work is needed to gather and incorporate all available input from stakeholders including device 

manufacturers, public utility commissions, weights and measures officials, smart grid experts, and all others that are 

in a position to contribute to the development of a method of sale for electricity as vehicle fuel. T hus, it is 

recommended that this item be taken up as a Developing Item to encourage input from stakeholders and experts in 

the development of proposed definitions, method of sale requirements, retail equipment price posting and labeling 

requirements, and any other elements needed to advance the item for adoption.

While a s pecific proposal for consideration has yet to be developed, some preliminary examples and points to 

consider are offered below:

2.XX.1. Definitions.

(a) Electric Vehicle or Hybrid-Electric Vehicle. – A vehicle that employs electrical energy as a primary 

or secondary mode of propulsion.

(b) Plug-in Electric Vehicle (PEV). – An electric vehicle that has onboard electrical energy storage 

designed to be charged via a physical connection to an external source of electrical energy.

(c) Electricity as Vehicle Fuel. – Electrical energy transferred to and/or stored onboard an electric vehicle 

primarily for the purpose of propulsion. 
L&R Committee 2013 Final Report

L&R - 37

(d) Electric Vehicle Supply Equipment (EVSE). – A device or system used to transfer electrical energy 

to an electric vehicle, either as charge transferred via physical or wireless connection, by loading a 

fully charged battery, or by other means.

2.XX.2. Method of Retail Sale and Supply Equipment Labeling. – Preliminary review suggests that the 

method of sale should be based on metered quantities to facilitate value comparison by consumers. The units 

should be specified for all electrical energy kept, offered, or exposed for sale and sold at retail as vehicle fuel, 

such as electrical energy units in terms of kilowatt hours (kWh) and/or in the metric equivalent unit for 

electrical energy Joules (J).

2.XX.3. Retail Service Equipment Labeling. – The unit price on the basis of the method of sale will be 

important to consumers as a basis for a value comparison regardless of whether the electrical energy is 

delivered through a slow plug-in charging device, a fast charging device, or by battery replacement.

2.XX.4. Presentation of Price (Street Signs and Advertisements). – The unit price according to method of 

sale will be important to clearly represent on street signs and advertisements when a co nsumer must make a 

value comparison before pulling their vehicle into a station to purchase electrical energy.

Although many Plug-in Electric Vehicle (PEVs) are primarily charged in homes and at work, it is projected that 

there will be a growing need for public PEV charging stations in order to address public expectations and allow for 

successful adoption of PEV technology by the public. Several states have observed emergence of PEVs and made 

inquiries regarding direction of NCWM toward a method of sale for electricity as a vehicle fuel. O ne online

resource for locating charging stations at https://na.chargepoint.com/charge_point identifies nearly 1100 charging 

stations already deployed across the United States. U se of electric vehicles and hybrid-electric vehicles is 

increasing. A doption of electric vehicles is being driven by a number of factors, including high traditional fuel 

prices, auto industry investment in PEV technology, government investment and subsidies, national fuel economy 

standards, and state and national zero-emission vehicle and greenhouse gas standards.

A single, consistent method of sale is needed to pave the way for accurate measurement and representation of 

quantities sold and to facilitate value comparison by consumers. The method of sale is a crucial element that must 

be in place before the suitability of measurement methods and device technologies can be assessed. A measurement 

that is accurate, consistent, and understandable will promote consumer confidence and will provide consumers with 

a fundamental tool to perform value comparisons and protect themselves from confusion and fraud. An electrical 

energy-based method of sale would accomplish this.

Other methods of publicly offering electrical energy for sale as vehicle fuel have appeared in the absence of a 

nationally standardized method of sale. These include time-based charges, subscriber access, and gratis (free of 

charge) access. The coexistence of multiple methods of sale for the same commodity frustrates consumers’ efforts 

to make informed value comparisons. 

The actual value to a motorist of the electrical energy that is received during charging is in terms of the distance that 

they are able to travel. The increase in the distance traveled after receiving a charge is dependent on the amount of 

electrical energy that was delivered during the charging event. The amount of charge the vehicle receives during a 

charging event cannot be determined solely by measuring the time it was connected to the charging system. The 

rate per time the charge is delivered will depend on many factors that cannot be controlled including, but not limited 

to, the starting charge level, the design of the vehicle battery, the type of charging equipment, and other 

environmental variables. For these reasons, a time based method of sale will not form a sound basis for a consistent 

value comparison and an electrical energy-based method of sale is strongly recommended.

The current equipment for vehicle charging that is available in the marketplace today represents a very wide range 

of charging speeds, further emphasizing the need for a single method of sale. Level 1 equipment charges vehicles 

with 110 VAC and can take from 8 hours to 12 hours to fully charge a vehicle. In contrast, a fast DC type of 

Electric Vehicle Supply Equipment (EVSE) is capable of charging a vehicle from 20 % to 80 % of full charge in 

10 minutes, closely approximating the time of a traditional liquid (e.g., gasoline) vehicle fueling cycle. Consumers 

place a high value on their time; therefore, it is reasonable to expect that the unit price for electrical energy from a 

device capable of very fast charging will be higher. This can also be anticipated because the equipment capable of 
L&R Committee 2013 Final Report

L&R - 38

faster charging represents a higher capital investment. Since stations may offer multiple options for charging speed, 

a uniform language for describing the type of charging equipment available by providers should be developed so 

that this important aspect of consumer value can be presented consistently in conjunction with the unit price to aid in 

the value comparison. 

Vehicle charging using types of EVSE that offer slower charging rates is often offered in conjunction with other 

paid services (e.g., parking, valet parking, routine vehicle maintenance). In these cases, the unit price for electrical 

energy offered should be presented separately from any price for the other paid service(s) to allow for a v alue 

comparison with the cost of electrical energy offered by other providers.

For reference, a typical PEV can hold a charge of 24 kWh in onboard storage, with some vehicles capable of holding 

as high as 75 kWh. The average price of electrical energy in the United States is $0.075 per kWh and the average 

price for residential electrical energy is $0.089 per kWh. Presuming that the price for electrical energy as a vehicle 

fuel might range from $0.10 kWh to $0.50 per kWh (perhaps depending on the speed of the ESVE charger), then the 

cost to the consumer to fill a vehicle might range from $2.40 to as high as $37.50. 

An additional issue that needs to be explored and developed is that of “battery exchanges.” Equipment already 

exists that allows consumers to swap a d epleted storage device for a fully charged onboard storage device 

(i.e., battery). In this case, the amount of charge present in the fully charged device should to be communicated to 

the consumer consistent with the method of sale to enable a value comparison between this method and plug-in 

ESVE charging. The issue of whether and how to credit a consumer for the amount of charge that exists in the 

battery that is to be removed should be considered as this item develops.

There are currently as many as eight manufacturers of EVSE that would benefit from clear direction on method of 

sale and device standards.

The National Association of Regulatory Utility Commissioners (NARUC) and other local Public Utility 

Commissions (PUC) interests have identified PEV use, and particularly public re-charging use cases, as having 

potentially significant impact on Public Utility efficiency, infrastructure needs, and pricing structures. Collaboration 

with these organizations in the development of national legal metrology standards for electrical energy sold as 

vehicle fuel would offer an opportunity for the creation and implementation of standards that take into consideration 

the missions of both NARUC and NCWM.

There is a likelihood that stations owned and operated by public utilities will coexist with privately owned charging 

stations. There may be regulatory issues in some jurisdictions that effect price regulation and competitiveness 

between these two types of stations. This is another reason that NARUC and PUC input is critically needed on 

development of a method of sale.

In Comments of the Division of Ratepayer Advocates to the California PUC (see Section II.A

www.dra.ca.gov/NR/rdonlyres/B2E02349-740A-4EA8-A4D0-69ED3C0D6623/0/R0908009DRAComments_A1b.pdf), 

the question has also been raised as to whether PUCs may require residential customers to install a separate electric 

sub-meter for PEV charging. If this occurs, it is most likely that consumers would be invoiced for charging their 

vehicles at home in the same kWh units that are used for their primary billing. If the method of sale at public 

charging stations matches the units that are billed for charging the same vehicle at the residence, this will further 

facilitate the value comparison by consumers.

In some states, electrical energy sub-metering already falls under the jurisdiction of state and local weights and 

measures authorities. These jurisdictions must now use established standards other than NIST Handbook 44 and 

NIST Handbook 130. National standards for the sale of electrical energy in NIST Handbook 44 and NIST 

Handbook 130 would promote greater uniformity on sub-metering applications.

2011 CWMA Interim Meeting: An official suggested referencing FTC for labeling on alternative fuels. CWMA did 

not forward the item to NCWM and recommended returning the item to the submitter for development.
L&R Committee 2013 Final Report

L&R - 39

2011 WWMA Annual Meeting: An official commented that such vehicles already exist and there is no need for this 

matter to be addressed by NCWM. The Committee acknowledged that new technology is in the marketplace and 

encouraged NCWM to develop a method of sale for electricity as a vehicle fuel. WWMA forwarded the item to 

NCWM, recommending it as a Developing Item. 

2011 NEWMA Interim Meeting: An official questioned how consumers will be charged, how the effort will be 

monitored, and whether this would be considered a r egulated utility. N EWMA forwarded the item to NCWM, 

recommending it as a Developing Item. 

2011 SWMA Annual Meeting: An official asked for clarification regarding the definition of an electric or hybrid 

electric vehicle. A NIST Technical Advisor noted that there is an absence of a cl early defined method of sale. 

Inquiries regarding the correct method of sale have increased as growth in charging stations have grown. T he 

Technical Advisor asked that this item be made Developing because much information needs to be gathered. A 

couple of officials responded that only their utility companies can sell electricity. It was recognized that public 

utilities need to be an integral part of the process. An official questioned whether a measuring device for electricity 

exists today, and whether it was National Type Evaluation Program certified. T here was also a question as to 

whether a test measure can be traceable and certifiable to a standard. An official expressed support for this item. 

SWMA forwarded the item to NCWM recommending it as a Developing Item. 

2012 NCWM Interim Meeting: Concern was expressed with the definitions for primary and secondary and that the 

item only deals with vehicle fuel. At this time, there is no proposal under consideration, and the language under the 

area “background/discussion” is to be considered. T he NIST Technical Advisor remarked that NIST, OWM is 

gathering data and information from many resources. Eventually a work group will be formed to further develop 

this item. The Committee designated this item as a Developing Item. 

2012 NEWMA Annual Meeting: A n attendee commented that these devices are not utility meters; they are 

subsidiary meters that fall under weights and measures authority. Another attendee voiced support as a developing 

item because businesses are installing these sub-meters and a uniform method of sale is needed. NE WMA 

recommended that the item remain as a Developing Item.

2012 CWMA Annual Meeting: A regulatory official remarked that this is not a public utility and owners of these 

charging units make free market sales. States should be concerned that this is a rapidly growing market without any 

standard. Other states commented; one stating that charging stations are selling by time, not kilowatt hour and the 

other stating that the charging stations are a free service for now. A regulatory official remarked that there are quick 

and slow charging stations and recommended that consumers be charged on what the vehicle is capable of receiving 

rather than what the device is capable of delivering. CWMA recommended that the item remain as a Developing 

Item.

2012 NCWM Annual Meeting: NIST, OWM announced that a NIST work group has been formed to develop this 

item and there are two meetings schedule over the next several months. A preliminary draft code has been 

developed, which closely follows the California standard. Two regulatory officials expressed urgency in developing 

this proposal.

2012 WWMA Annual Meeting: Ms. Kristin Macey (California) supported the item, stating that regulations would 

provide clear authority in the marketplace. Ms. Macey also reminded the states to look at their signage laws to see if 

there is an impact. Ms. Juana Williams, NIST Technical Advisor and Chair of the Electric Vehicle Fueling and 

Submetering (EVF&S) Work Group (WG) reported that they held their first web-based meeting on August 29, 2012. 

They covered the structure and goals of the WG and membership status (active or observer) of each attendee was 

established. The next meeting will be held in person at NIST in Gaithersburg, Maryland, with an option to attend 

via webinar at a date to be determined in December 2012 or January 2013. The group will discuss technical issues 

for the first time at this next meeting. NIST has provided the work group with draft proposals for a new 

Handbook 44 code and a draft NIST Handbook 130 method of sale. The draft code will be starting points as the 

group fully develops these two items. WWMA recommended that the item remain as a Developing Item.

2012 SWMA Annual Meeting: SWMA recommended that the item be an Informational Item.
L&R Committee 2013 Final Report

L&R - 40

2012 NEWMA Interim Meeting: NEWMA members again expressed urgency for a final product on the topic. This 

should be given a higher priority by the WG as more charging stations are appearing without specific guidance on 

method of sale placing the consumer at a disadvantage.

2013 NCWM Interim Meeting: Ms. Williams provided the Committee with a status report and the latest language 

for consideration of the findings of the WG. Ms. Williams also remarked that the WG would like to see this item 

move forward as a Voting Item. Several states voiced support for this item and encouraged regulators to be active 

with this WG. T he L&R Committee is recommending this move forward as a V oting Item. The CWMA and 

NEWMA agree that this is item clarifies the Method of Sale for Retail Sale. This will allow the S&T Committee to 

work with stakeholders and regulators to develop test procedures. 

2013 NCWM Annual Meeting: EVFS Chair, Ms. Williams gave a briefing on the status of the EVF&S WG meeting 

held at NIST in Gaithersburg, Maryland, on June 11, 2013. Mr. Jim Creevy (NEMA) and a member of the 

EVF&S WG submitted language that was developed by the WG on June 11, 2013, (refer to Appendix D in this 

report, Report of the 98th National Conference on Weights and Measures [2013]). However, there was no consensus 

between industry and regulators on this specific language. The Committee proposed the language under the Item 

Under Consideration move forward as a Voting Item.

style letters and the color shall be in definite contrast to the background color to which it is applied.

(Added 2007) (Amended 20XX)

Background/Discussion: 

The current wording in NIST Handbook 130 related to fuels restricted to use in Flex Fuel Vehicles should be 

reviewed. I nput gathered from the regional meetings and other stakeholders will be used by FALS to develop 

recommended modifications to NIST Handbook 130. 

2013 NCWM Annual Meeting: Mr. Chuck Corr, Chair of the task group under FALS provided initial language 

changes for a Section 2.30. E85 Fuel Ethanol Flex Fuel Blends. There is additional work being done by this task 

group under the L&R Committee Item 237-9.

LUBRICANTS REGULATION 

237-1 I Section 1. Definitions – Diesel Liter Equivalent (DLE) and Diesel Gallon Equivalent 

(DGE)

Source: 

Clean Vehicle Education Foundation (2013)

Purpose: 

Enable consumers to make cost and fuel economy comparisons between diesel fuel and natural gas.

Item Under Consideration: 

Amend NIST Handbook 130, Engine Fuels and Automotive Lubricants Regulation as follows. 

Section 1. Definitions

1.XX. Diesel Liter Equivalent (DLE). – means 0.756 kg of natural gas. 

(Added 20XX)

1.XX. Diesel Gallon Equivalent (DGE). – means 2.863 kg (6.312 lb) of natural gas. 

(Added 20XX)

Background/Discussion: 

The gasoline gallon equivalent (GGE) unit was defined by NIST/NCWM in 1994 (refer to Appendix B in this 

report, Report of the 98th National Conference on Weights and Measures [2013]) to allow users of natural gas 

vehicles to readily compare costs and fuel economy of light-duty natural gas vehicles with equivalent gasoline 

powered vehicles. For the medium and heavy duty natural gas vehicles in widespread use today, there is a need to 

officially define a unit (already in widespread use) allowing a comparison of cost and fuel economy with diesel 

powered vehicles. Also, natural gas is sold as a vehicle fuel as either Compressed Natural Gas (CNG) or Liqufied 

Natural Gas (LNG) and each method of sale in measure in mass. Therefore, the generic term for natural gas is 

proposed to be used in NIST Handbooks 44 and 130 without the existing term "compressed." The mathematics 

justifying the specific quantity (mass) of natural gas in a DLE and DGE is included in Appendix B of this report 

(Report of the 98th National Conference on Weights and Measures [2013]). 

The official definition of a DLE and a DGE will likely provide justification for California, Wisconsin, and any other 

state to permit retail sales of LNG for heavy-duty vehicles in these convenient units. 
L&R Committee 2013 Final Report

L&R - 42

2012 CWMA Interim Meeting: A regulatory official commented that there is no standard for Diesel Gallon 

Equivalent (DGE), and LNG and CNG are being sold in Wisconsin and other states as DGE in order to compete 

with diesel sales. As a result, a standard is urgently needed. DGE sales are occurring in the marketplace without a 

standard. The Committee recommended that FALS review the conversion factors for DGE and LGE for accuracy. 

CWMA supported this item and forwarded the item to NCWM, recommending it as a Voting Item.

2012 WWMA Annual Meeting: The Committee worked in tandem with the S&T Committee since it had a related 

item. Ms. Kristin Macey (California) opposed the item because it would cause complications in the marketplace. 

The Committee believed the item had merit but would like to know whether the values accurately represent the 

actual value of various types of natural gas products. It acknowledged there are different compositions and sources; 

for example, LNG has a higher methane composition. I s there also a possibility of additional conversion factors 

based on BTUs from different sources? The Committee requested outreach by NCWM to other stakeholders to get 

their involvement on these items. WWMA forwarded the item to NCWM recommending it as an Informational 

Item. 

2012 SWMA Annual Meeting: SWMA recommends review by the Fuels and Lubricants Subcommittee and 

forwarded the item to NCWM recommending it as an Informational Item. 

2012 NEWMA Interim Meeting: NEWMA reviewed the CWMA comments. A General Motors representative 

indicated that there is a lot of discussion on a point of reference. There was comment that both methods of labeling 

may be required on a d ispenser. T he labeling issue may create more confusion for the consumer. NEWMA 

recommended review by the Fuels and Lubricants Subcommittee (FALS). NEWMA forwarded the item to NCWM

recommending it as an Informational Item.

2013 NCWM Interim Meeting: A presentation in support of this item was given by Mr. Doug Horne (Clean Vehicle 

Education Foundation). Several comments were heard regarding the references and databases used to develop the 

calculations. C oncern was expressed with the conversion factors used. A NIST S&T Technical Advisor 

recommends that L&R and S&T Committees work in a joint session since there is a companion Item 337-1 on the 

S&T agenda. A collaborative effort between the L&R and S&T Committees will ensure that the proposed 

equivalent unit is dispensed accurately at the dispenser. S everal attendees spoke in support of the collaborative 

effort. T he Committee will request the NCWM Board of Directors create a steering committee that consists of 

experts and stakeholders to review this proposal. L&R Committee will prepare a list of comments that they would 

like the Steering Committee to review and address. The L&R Committee recommends this as Informational Item. 

2013 NCWM Annual Meeting: The Committee was informed the Natural Gas Steering Committee chaired by Mr. 

Mahesh Albuquerque would be reviewing this item.

Refer to Appendix B in this report (Report of the 98th National Conference on Weights and Measures [2013]) for

(Table 1. Amended 1997 and 20XX)

Background/Discussion: 

These NIST Handbook 130 octane changes will harmonize with an effort underway in the ASTM International 

(ASTM) Gasoline and Oxygenates Subcommittee to include a minimum motor octane number (MON) performance 

limit in gasoline. The naming of the various octanes is a function for weights and measures.

Nominally, vehicles manufactured after 1984 include engine computer controls maintaining optimal performance 

while using gasoline octane of 87 AKI or higher. The practice of altitude de-rating of octane, resulting in octanes 

below 87 AKI, reduces a v ehicle’s efficiency and fuel economy. Increasingly, more vehicles are boosted 

(turbocharged/supercharged) eliminating altitude intake air effects. Additionally, consumers using gasoline with an 

octane AKI below 87 will void their vehicle owner’s warranty. The Coordinating Research Council (CRC) Report 

No. 660, “Fuel Anti-knock Quality – Engine Response to RON (Research Octane Number) versus MON,” May 2011 

demonstrates the continued need for gasoline MON octane for the large bored, naturally aspirated U.S. engines. 

Setting an 82 MON minimum maintains the current MON level for today’s 87 AKI Regular Unleaded gasoline. A 

common U.S. octane specification between ASTM, NCWM, and Vehicle Owners Manuals will give states clear 

direction on how best to enforce proper fuel pump octane labeling and quality levels on behalf of vehicle consumers.

Leaded gasoline is not available at retail and, therefore, labeling guidance is not needed. 

Mr. Bill Studzinski (General Motors) gave a presentation at the 2012 CWMA Interim Meeting. He stated there is no 

minimum AKI specification in NIST Handbook 130. NCWM wants to align ASTM D4814 with NIST 

Handbook 130, but there is no minimum in ASTM D4814 and ASTM is looking at this. Less than 1 % of vehicles 

on the road today are 1984 or prior. All vehicle owner’s manuals stipulate 87 octane or higher. Using 85 octane in 

these vehicles causes slight reductions in efficiency and fuel economy. There should be harmonization between 

vehicles owner’s manuals, NCWM, and ASTM. The minimum AKI should be 87 and the minimum MON should 

be 82. Minimum octane of 87 is really an ASTM issue. A regulatory official believed that if we adopted this 

language it would provide the states with appropriate octane levels. The resource for octane is small, but currently 

OEMs are manufacturing for all vehicles to tolerate this fuel. A Renewable Fuels Association representative

commented that state regulators who are with NCWM regulate octane, and NCWM should have the standards and 
L&R Committee 2013 Final Report

not wait for ASTM. CWMA supports this item and forwarded the item to NCWM recommending it as a Voting 

Item. At the 2013 C WMA Annual Meeting, the Committee recommended this remain an Informational Item 

pending the outcome of the June 2013 ASTM ballot that is related to octane. 

Mr. Studzinski provided a presentation at the 2012 WWMA Annual Meeting. The Committee would like to have 

ASTM and FALS work in tandem to develop a proposal that provides a phase out period. The Committee 

recommended a modification to the proposal to allow for the Table 1. Minimum Antiknock Index Requirements

chart to remain with Section 3.2.5. Prohibition of Terms. WWMA forwarded the item to NCWM recommending it 

as an Informational Item as modified and presented as follows: 

2.1.4. Minimum Antiknock Index (AKI). – The AKI of gasoline and gasoline-oxygenate blends 

shall not be less than 87. The AKI shall not be less than the AKI posted on the product dispenser or as

2012 SWMA Annual Meeting: Mr. Bill Studzinski (General Motors), Chair of a FALS Task Group and ASTM 

provided a presentation supporting this item. The SWMA Committee acknowledged strong support from their 

Association, and forwarded the item to NCWM recommending it as a Voting Item.

2012 NEWMA Interim Meeting: Mr. Studzinski provided a presentation and summarized the position of the other 

regions. NEWMA forwarded the item to NCWM recommending it as a Voting Item. 

2013 NEWMA’s Annual Meeting: It was recommended the item remain Informational until FALS makes a 

recommendation to the Committee. 

2013 NCWM Interim Meeting: FALS could not reach agreement on this item during their Sunday work session. 

The Committee received and reviewed several letters in support of this proposal. D uring open hearings Mr. 

Studzinski provided a presentation. The Committee also received comments in opposition to the proposal citing the 

lack of consumer complaints with sub-octane, and it was requested that the Committee wait until the CRC study

Amend the NIST Handbook 130, Engine Fuels and Automotive Lubricants Regulation, Section 2.1.4. Minimum 

Motor Octane Number as follows:

2.1.4. Minimum Motor Octane Number. – The minimum motor octane number shall not be less than 82 

for gasoline with an AKI of 87 or greater;

Background/Discussion: 

In the early 1990s, the Table titled “Automotive Spark-Ignition Engine Fuel Antiknock Indexes in Current Practice” 

was removed from the body of ASTM D4814 and placed into an appendix in ASTM D4814. This appendix is nonmandatory information and is not part of the specification. It is inappropriate for NIST Handbook 130 to continue 

with the 82 motor octane number minimum for the following reasons: 1) 82 motor octane number minimum is not 

an ASTM D4814 specification; 2) FTC regulates octane posting and has no motor octane number minimum; 

3) neither the Kinder Morgan Pipeline nor the Olympic Pipeline requires a minimum motor octane number 

specification; and 4) the Colonial Pipeline has no motor octane number minimum for either Reformulated 

Blendstock for Oxygenate Blending or Conventional Blendstock for Oxygenate Blending.

Recent data shows a low motor octane number is actually preferable for the current fleet of vehicles. Motor and 

Research octane numbers are equally important to the performance of the motor vehicle engine. A minimum motor 

octane number requirement offers no more protection to the consumer than the road octane number that is the 

average of the Motor and Research octane numbers.

2010 SWMA and WWMA Annual Meetings and the 2010 CWMA and NEWMA Interim Meetings: A ll four 

associations forwarded the item to NCWM, recommending it as an Informational Item. The SWMA, CWMA, and 

NEWMA recommended that the item to be developed by FALS.

2011 NCWM Interim Meeting: Mr. Ron Hayes, FALS Chair, reported that the Subcommittee recommended this 

item be Informational to allow more time for data to be reviewed. H istorical data exists and a Coordinating 

Research Council (CRC) study is being done that will clarify issues and provide data that will assist with making a 

decision. There were no comments heard from the floor during Open Hearings. The 2011 L&R Committee 

designated this item as an Informational Item.

2011 NEWMA Annual Meeting: There were no comments heard on this item. The NEWMA L&R Committee 

recommended that this item move forward as an Informational Item.

2011 CWMA Annual Meeting: The FALS Chair indicated that they are waiting for results from the CRC study and 

recommends this remain Informational because it is not fully developed. The CWMA L&R Committee 

recommends that this item move forward as an Informational Item.

2011 NCWM Annual Meeting: It was noted that FALS was continuing to monitor and develop this item and the 

CRC was reviewing and analyzing the data from the CRC 660 study and additional industry data.

2011 CWMA Interim Meeting: Mr. Hayes said most new cars respond better to the research octane number rather 

than to the anti-knock index; however, this was still being studied by the CRC and research was ongoing. CWMA

recommended that the item remain as an Informational Item. 

2011 WWMA and SWMA Annual Meetings and the NEWMA Interim Meeting: All three associations 

recommended that the item remain as an Informational Item. 

2012 NCWM Interim Meeting: FALS held a work session and heard no objections to recommending this item as

Informational. Mr. Hayes reported to the Committee that a Task Group under FALS continues to work on this item. 

Mr. Albuquerque (Colorado), Task Group Chair, reported that information is still being gathered and recommended

that it be an Informational Item. The 2012 L&R Committee designated this item as an Informational Item. 

2012 NEWMA Annual Meeting: One person remarked that this is a non-issue. NEWMA recommended that the 

item remain as an Informational Item.

2012 CWMA Annual Meeting: No comments were received. CWMA recommended that the item remain an 

Informational Item.

2012 NCWM Annual Meeting: Two industry representatives supported further development of this item by the 

Task Group. Mr. Bill Studzinksi (General Motors) will be leading the discussion on this item for the FALS. A 

stakeholder remarked that we do not need a task group for this item, and we should refer to ASTM.

2012 CWMA Interim Meeting: An oil company representative commented that ASTM does not have a minimum 

MON (Motor Octane Number) but recommends waiting for data from CRC. He recommended that the item remain 

Informational until the CRC data is available. General Motors commented that the available CRC data is still 

important. That data says that MON is still important. CWMA was neutral on the item and recommended that the 

item remain Informational until CRC octane data is available and reviewed by FALS.

2012 WWMA Annual Meeting: There were no comments. The Committee recommended that ASTM and FALS 

work in tandem to develop a proposal that provides a phase-out period. WWMA recommended that the item be an 

Informational.

2012 SWMA Annual Meeting: An industry member commented that this item, which was submitted several years 

ago, would be in conflict with the new item received this year; so if the new item goes forward, this item would be 

Withdrawn. SWMA supports this new item. SWMA recommended that the item be Withdrawn.

2012 NEWMA Interim Meeting: General Motors commented that CRC is working to produce data on this topic. 

Discussions indicated that this is contradictory to previous agenda item and should be Withdrawn. The Committee

recommended if this item goes forward to NCWM, it should be assigned to the Fuels and Lubricants Subcommittee. 

NEWMA recommended that the item be Withdrawn.

2013 NCWM Interim Meeting: A stakeholder recommended that this item be Informational until it is further 

developed by ASTM. Mr. Hayes remarked that the FALS is also recommending this to be Informational. The 

Committee agrees and made this an Informational Item.

Background/Discussion: 

The vast majority of engine oil used at professional fast lube facilities is the most current category of American 

Petroleum Institute (API) licensed oil. However, older, specialty, and some non-American vehicles take engine oil 

not listed as active under API’s private regulatory scheme; some are former API licensed oils now considered 

“obsolete” or “inactive” and some are simply licensed by another organization like ACEA. However, if the original 

equipment manufacturers (OEM) recommend those engine oils for their vehicles, consumers have a r ight to use 

them regardless of API’s blessing, and installers and retailers should be able to sell them without obstruction. 

The Automotive Oil Change Association (AOCA) amendment is necessary because a cau tionary statement 

appearing on service receipts without explanation will inappropriately mislead consumers with older and uncommon 

model vehicles into believing they should not use OEM-recommended engine oil. The average fast lube customer 

does not recognize API or SAE (Society of Automotive Engineers) to mean anything in particular but “CAUTION” 

and “OBSOLETE” in big capital letters could only be understood as negative. Scaring consumers in this way will 

not only push them to buy more expensive engine oil they don’t need, but also engender distrust in their installer 

service providers for recommending and/or using OEM-recommended engine oil.

The average age of cars in the current fleet is nearly 11-years old, and it is not unusual for fast lubes to have 

customers with vehicles twice that age; for example, there are millions of opportunities for consumers to be misled 

into rejecting proper engine oil. The fact is American consumers are hanging onto their vehicles longer than API is 
L&R Committee 2013 Final Report

L&R - 49

hanging onto its service categories. When API designates a m otor oil category as inactive, this does not mean 

consumers with vehicles designed to use that category turn in their cars or otherwise want to buy a more expensive 

grade of motor oil going forward. Therefore, a category of motor oil designed to work for particular makes and 

models of vehicles should not be burdened with the chilling effect of a ca utionary statement absent a specific 

clarification acknowledging the preeminence of the OEM’s recommendations.

The new standard phase-in factor must be considered as well. When API publishes a new edition of 1509, Engine 

Oil Licensing and Certification System, and/or creates a new service category, a reasonable phase-in period for bulk 

oil stock is necessary to accommodate older vehicle owners’ needs; for example, it may be in those customers’ best 

interests—both functionally and economically—to use motor oil developed in accordance with an earlier edition or 

service category so long as the automobile manufacturer originally recommended it and its continued use has no 

impact on any remaining warranty coverage. Although it is common for API to retain a couple of the most recent 

service categories as “active,” API could choose to make all but the most recent service category “obsolete.” For 

fast lube operators to automatically upgrade bulk oil stock at API-determined intervals would be tantamount to 

giving API control over the price of oil change services regardless of what the market can bear. And, what about 

packaged engine oil products already on the shelf or in the distribution chain when API makes a unilateral decision 

to deactivate an engine oil category? As a practical matter, tens of thousands of retailers and installers cannot remark millions of packages to coincide with API’s timing or take the financial hit for sending it all back in violation 

of purchase agreements. Attempting to enforce the labeling requirement at this level would be a nightmare for 

everyone involved. The way to avoid this problem is to adopt AOCA’s amendment so that the requirement for 

proper labeling of packaged containers of engine oil rest with the party in control of the packaging – the 

manufacturers. 

Without the amendment, the labeling requirement will be very difficult to enforce given the inventory of packaged 

goods remaining after an active engine oil category has been declared inactive or obsolete. Fast lubes would 

experience catastrophic business loss if customers with older and uncommon model vehicles were alienated. 

Maintenance costs for consumers with older model cars could easily double if they are confused into believing they 

need the latest category of engine oil.

AOCA contends that the proposed amendment will accomplish three important goals: 1) prevent unintended 

consumer confusion and product stigma from using a cautionary statement by reestablishing the connection to OEM 

recommendations; and 2) provide the necessary exemption to protect retailers and installers for selling unlawful 

packaged inventory; which leads to 3) an increase in practical enforcement prospects.

The most analogous regulatory situation to the one at issue in AOCA’s proposed amendment is found in the Federal 

Trade Commission’s (FTC) Test Procedures and Labeling Standards for Recycled Oil (16 CFR 31, 

www.gpo.gov/fdsys/pkg/CFR-2011-title16-vol1/pdf/CFR-2011-title16-vol1-part312.pdf). In the rulemaking 

process, FTC specifically rejected requiring recycled engine oil to be labeled “recycled” because of the stigma 

associated with the term at that time (see 72 FR 14410 – 14413 & FN11, 1 H.R. Rep. No. 96–1415, 96th Cong. 

2d Sess. 6 (1980), reproduced at 1980 U.S. Code Cong. & Ad. News 4354, 4356. ‘‘Oil should be labeled on the 

basis of performance characteristics and fitness for its intended use, and not on the basis of the origin of the oil.’’). 

The National Automobile Dealers Association also commented in favor of this approach: “NADA further stated 

that by not requiring that ‘‘substantially equivalent’’ recycled oils be labeled ‘‘recycled’’ or ‘‘re-refined,’’ used oil 

processors are able to market their products effectively.” (72 FR at 14411) N o “recycled” or other potentially 

derogatory designation is required so long as the finished product meets the appropriate API standard.

2012 CWMA Interim Meeting: AOCA stated that oil change businesses are small businesses without legal staff and 

they need clear guidance. These businesses follow the OEM recommendations, which recommend oils that do not 

follow API or SAE standards. The language should acknowledge that some manufacturers approve and recommend 

their own oil (i.e., General Motors (GM) and Audi-Volkswagen.) AOCA thought the current language required all 

OEM oils that did not meet a specific API performance standard to be labeled as obsolete. A GM representative

confirmed that GM produces their own oil, Dexos (the best oil for any car), which does not have an API 

certification. A FALS member shared the API motor oil guide, (refer to Appendix C in this report, Report of the 

98th National Conference on Weights and Measures [2013]) which labels specific categories of oil as obsolete. If a 

manufacturer does not label the oil with an API obsolete category, the product is not considered to be obsolete. 

OEM manufacturers that were named do not label their oil with an obsolete category, and so oil changers do not 
L&R Committee 2013 Final Report

L&R - 50

need to worry about the obsolete label being used on OEM motor oils. AOCA also asked if there would be a grace 

period to sell product purchased prior to January 2013. States regulators clarified that nothing is written in the 

regulation, and grace periods would be determined on a state by state basis. AOCA reiterated that the language 

should clearly state that OEM oils that do not have API certification are not obsolete. AOCA also stated that 

installers should not be responsible for labeling on packaged products received. A regulatory official stated retailers 

in other industries are responsible for labeling on packages received, and it would be an unfair market advantage to 

allow some retailers to use products that were illegally labeled. Since the current language is not clear about exactly 

what oils are obsolete, the Committee recommended that FALS produce language for the NCWM Interim Meeting 

clearly stating that OEM recommended oils that are not API certified are not obsolete. CWMA forwarded the item 

to NCWM, recommending it as a Voting Item with the stipulation that FALS develop the clarifying language.

2012 WWMA Annual Meeting: Ms. Kristin Macey (California) opposed this item because it removes the retailer’s 

accountability. Mr. Kevin Ferrick (API) opposed the additional language. Mr. Ferrick also provided a presentation 

to the WWMA and written comments to the Committee. Mr. Kurt Floren (Los Angeles County, California) opposed 

the language for similar reasons as stated by Ms. Macey. WWMA did not forward the item to NCWM.

2012 SWMA Annual Meeting: An API representative voiced API’s opposition to the item and provided the written 

testimony in dispute of the comments and claims made by the submitter. The SWMA Committee believed there was 

lack of support for the item and that the oil change industry has a poor understanding of the API standards. SWMA 

did not forward the item to NCWM.

2012 NEWMA Interim Meeting: API stated that it opposes the item and that specifics have been submitted in 

writing. API suggested this proposal and Item 237-4 be Withdrawn. General Motors indicated the proposal appears 

to allow older formulations of engine oil, but newer formulations give better performance, even in older vehicles. 

GM prefers current formulation of engine oil. NEWMA did not forward the item to NCWM.

2013 NCWM Interim Meeting: A state opposed this item and would like to see it Withdrawn. The FALS Chairman 

remarked that there are several engine oils designed for specific model vehicles and FALS is working to resolve this 

issue. A Committee member remarked that a statement of accountability should be within the language. T he 

Committee would like to see additional language developed by FALS and made this an Informational Item. 

2013 NCWM Annual Meeting: FALS submitted modified language for Sections 3.33.1.4. Engine Service Category, 

3.33.1.4.1. Vehicle or Engine Manufacturer Standard, and 3.33.1.4.12. Inactive or Obsolete Service Categories. The 

Committee would like to have regional input on this modified language to review at the 2014 NCWM Interim 

Meeting. The Item Under Consideration contains this modified language.

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to 

Appendix B in the Report of the 97th National Conference on Weights and Measures (SP 1160, 2012), and

Background/Discussion: 

There is a chain of engine oil purchasers involved in the sale of bulk engine oil, all of whom need accurate and 

adequate information about the commodity so that they can make price and quantity comparisons. The engine oil 

distributor is a purchaser with respect to engine oil manufacturers, the installer is a purchaser with respect to engine 

oil distributors, and the consumer is a purchaser with respect to installers. Installers like fast lube operators can only 

provide accurate and adequate information about bulk engine oil to consumers if their distributors provide it at the 

point of delivery. It would be manifestly unfair to expect installers to legally vouch in writing for the quality of 

distributors’ engine oil products absent a corresponding written verification requirement.

The original language for consideration (refer to the Report of the 97th National Conference on Weights and 

Measures [SP 1160, 2012], L&R Committee Report) creating a Method of Sale for Section 2.33.1.4.2. Tank Trucks 

and Rail Cars and an Engine Fuels and Automotive Lubricants Regulation for Section 3.13.1.4.2. Tank Trucks or 

Rail Cars inadvertently created a loophole for distributors to avoid providing necessary product documentation at the 

time of delivery. 

Whether or not NCWM waives tank truck labeling is not the issue. The problem lies in the converse this provision 

allows: if a distributor displays the SAE viscosity grade and service category on a tank truck, then they do not have 

to provide a bill of lading. This poses a serious risk to installers like fast lubes because the regulation requires them 

to vouch for viscosity grade, service category, and brand on customer receipts but does not guarantee that they will

receive that same information in writing from their distributors—the parties with actual control over product 

quality/identity. 

There is also no practical way for fast lubes or NCWM to enforce this “either/or” regulatory scenario. If a 

distributor arrives at an installer’s facility without documentation, how can the installer hold the distributor to it 

under NIST Handbook 130? The distributor can simply claim their truck is adequately marked. Installers are not 

professional truck inspectors; they cannot be expected to act as enforcement agents in this scenario. Meanwhile, in 

order for local weights and measures officials to hold a distributor accountable, the official would have to arrive on 

the scene at the time of delivery, which is unlikely at best. Any subsequent official inquiry would take place after 

the distributor has had the opportunity to subsequently mark any unmarked truck at issue. Moreover, risk of 

distributor failure in providing necessary documentation is high because most do not and never have been willing to 

provide bills of lading or other documentation to fast lubes at the time of delivery.

Additionally, the imperative for any installer labeling and/or receipt information requirements to be matched by 

corresponding requirements for engine oil distributors includes “brand.” Installers cannot purport to verify via any 

form of documentation information that distributors have not documented at delivery. Method of Sale,

Section 2.33. Oil and Engine Fuels and Automotive Lubricants Regulation, Section 3.13. Oil requires installers to 

verify brand in writing and, therefore, distributors should be required to verify it, too. For NCWM to require 

otherwise would be manifestly unfair to installers by subjecting them to liability for the bad acts of distributors 

without any paperwork trail to rely upon in their own defense.

No one has more at stake than installers. Should a product quality problem occur with packaged goods, it’s 

relatively easy to trace the goods back to the manufacturer. However, this is not the case with motor oil transported 

in bulk; it all looks alike, it may have “changed hands” numerous times before reaching the fast lube facility, and 

even with testing can be impossible for a fast lube to verify because oil companies use chemical markers that only 

they can identify. Since motor oil specifications have become so precise and so expensive–fast lube operators stand 

to lose thousands of dollars every time a distributor delivers a lesser product. Moreover, when a distributor delivers 

the wrong product, it’s the fast lube operator who gets stuck holding the bag for consumer claims, which can be 

excessive if the “wrong” product did or could cause engine damage. It takes weeks before a bad load of motor oil is

detected and by then anywhere from 500 to 700 customers has been serviced. The remedy? All of the customers 

must be called back and re-serviced for free before any damage has the opportunity to occur. Requiring distributors 

to provide the same documentation required of installers represents the minimum necessary step to at least protect 

installers from misrepresentation claims when a distributor “mis-delivers” bulk oil.

API and ILMA have been publicly quoted as supporting the requirement that distributors provide documentation at 

delivery as the new paragraphs at issue already mandate it under all circumstances. See Lube Report (August 

1, 2012) www.imakenews.com/lng/e_article002489327.cfm?x=b11,0,w

EPA’s Federal Used Oil Management Standards require detailed transporter chain of custody documentation 

(40 CFR Part 279). See also EPA’s Chain-of-Custody Procedures for Samples and Data (www.epa.gov/apti/coc/), 

which makes clear that failure to maintain a proper chain of custody regarding samples and/or data will destroy any 

ability to defend oneself if challenged.

According to the U.S. Department of Agriculture (USDA), segregation and documentation for specialty (bulk) crops 

continue from the elevator to the final producer or consumer. [Traceability in the U.S. Food Supply: Economic 

Theory and Industry Studies (USDA Economic Research Service 2004)]. 

Under the FDA Food Modernization Act (Public Law 111-353), documenting the production and distribution chain 

of food products is required so that “in case of a problem, a product can be traced back to the source.”

DOT overlaps with EPA regarding the Federal Hazardous Waste Manifest System (40 CFR Part 262), which 

mandates detailed documentation of hazardous waste from cradle to grave; for example, from generator to 

transporter to end user/disposal.

2012 CWMA Interim Meeting: AOCA stated that the current language would allow the distributor to either label 

the truck or tank car or the bill of lading. The language should clearly state that distributor needs to provide the 

retailer with a bill of lading or other documentation that includes product identity information. A FALS member 

acknowledged that the current language could be construed to say that the distributor does not need to provide this 

documentation, and this was not the intent. The Committee recommends that FALS provide concise language that 

states that a bill of lading or other documentation with appropriate product information must be provided to the 

retailer. FALS should submit proposed language to the NCWM L&R Committee for the Interim meeting. CWMA 
L&R Committee 2013 Final Report

forwarded the item to NCWM, recommending it as a Voting Item with the stipulation that FALS develop language. 

In 2013 at the CWMA Annual meeting there was continued support for this to be a Voting Item. 

Mr. Ferrick provided a presentation at the 2012 WWMA Annual Meeting. Mr. Ferrick remarked that the submitted 

proposal was rather wordy; however; he does not disagree with the language. M s. Kristin Macey (California) 

supported the submitted proposal. The Committee agreed that the submitted proposal is too lengthy and presented 

alternative language for consideration. T he Committee regretted that the submitter was not present to answer 

questions. WWMA forwarded the item to NCWM, recommending it as an Informational Item as modified:

3.13.1.4.5. Tank Trucks or Rail Cars. – Tank trucks, rail cars, and other types of delivery trucks that are 

used to deliver vehicle engine (motor) oil are not required to display the SAE viscosity grade and service 

category or categories, however as long as the bill of lading or other documentation shall provides that 

information. 

2012 SWMA Annual Meeting: The committee agreed that adequate documentation should be provided. SWMA 

recommends this as a Voting Item. 

2013 NEWMA Annual Meeting: The NEWMA L&R Committee believes this item is fully developed and 

recommends this to be a Voting Item.

2013 NCWM Interim Meeting: Mr. Hayes remarked that FALS is recommending language changes for this item. 

FALS developed Section 3.13.1.6. Documentation, which resolves the issues brought before the Subcommittee. 

FALS recommended to the Committee that the revised language move forward as a Voting Item. The Committee 

concurs with the language revisions and proposed this item be a Voting Item. At the 2013 NCWM Annual Meeting 

FALS informed the Committee that this item is fully developed. The Committee recommended the item be 

presented for a Vote.

disclosing the actual percent by volume of biodiesel as required in 

Section 3.15.3. Documentation for Dispenser Labeling Purposes. However, the term 

“Contains Biodiesel” or other similar terms shall be used.

(Added 2005) (Amended 2008 and 20XX) 

Background/Discussion: 

2009 SWMA Annual Meeting: A discussion over blending was presented by a FALS member. Biodiesel is being 

blended at many terminals across the country in concentrations up to 5 %. Marketers downstream of the terminal 

are then attempting to blend additional biodiesel to target levels, and finding that their product is being over-blended 

because they were not aware that the fuel contained any biodiesel. According to Mr. Jennings (Tennessee 

Department of Agriculture) at least one major truck stop operator has already voiced concerns to the FALS Chair. 

This amended proposal will remove the exemption declaration of biodiesel content on product transfer documents 

for biodiesel blends up to 5 %. Biodiesel is blended at terminals in concentrations up to 5 %. Mr. Jennings believed

it was important to start this recommendation and have the FALS Chair get the proposal out to all members of the 

FALS for their comments before NCWM Interim meeting in January 2010. SWMA forwarded the item to NCWM, 

recommending it as a Voting Item.

(Added 2005) (Amended 2008 and 20XX) 

2010 NCWM Interim Meeting: Mr. Hayes, FALS Chair, gave an update on the Subcommittee’s work to remove the 

current exemption for biodiesel disclosure in diesel fuel at 5 % and below on product transfer documents.

A draft of substitute language was circulated among FALS members prior to the Interim Meeting. This substitute 

language expanded the disclosure of biodiesel content on all transfer documents (not limited to ones to the retailer) 

and for levels greater than 1 % biodiesel. The substitute was an attempt to find middle ground. FALS members 

were more agreeable to this substitute, but many still thought more work was needed.

The L&R and FALS received seven letters (refer to L&R Appendix E within the Report of the 95th National 

Conference on Weights and Measures [SP 1115, 2010]) that do not support this proposal as stated. The Committee

does support working on this issue and receiving feedback from industry. There is concern with the documentation 

and comingling of fuels. If fuel is comingled, it would need to be sampled every time, which could be quite costly.

An official requested that this item move forward as a Voting Item and meanwhile NEWMA and CWMA could

review and further develop the language at their spring 2010 meetings. API stated there are many things to consider, 

such as preemption language, cost implications, commercial issue of declaring with each transaction. A PI has 

worked with marketers, but there continues to be a difference of opinion and no consensus. It was voiced by 

industry that all biodiesel needs to be documented on the paperwork. If not, it puts the wholesaler, retailer, and 

consumer at risk. There was a comment from a stakeholder that they do not agree with API’s comment and that this 

has been a two-year battle on who gets to do the blending. Blenders are over-blending because they are not aware of 

what the current blend is. To prevent this situation, it would require disclosure on the transfer document. The 2010

L&R Committee designated this item as an Informational Item. 

2010 NEWMA Annual Meeting: A stakeholder reported that FTC has not changed the existing posting rule. 

NEWMA recommended that the item remain as an Informational Item. 
L&R Committee 2013 Final Report

L&R - 57

2010 CWMA Annual Meeting: S everal commented that the exact percentage of an alternative fuel needs to be 

known. Without the percentage being known, mislabeling can occur, which is not good for consumers, marketers, 

and the environment and renewable fuels. What is the downside of providing this information? A representative of 

the National Biodiesel Board (NBB) does not support this proposal and would like to have further discussions to 

seek what is best for the entire industry. T hey also commented that FTC declined to modify requirements for 

disclosure on product transfer documents for fuels containing 5 % or less biodiesel. An official disagreed that the 

exact percentage is necessary since it is the blender’s responsibility to test the product prior to blending. A 

representative of the Renewable Fuels Association would like to see the proposal expanded to include all additives 

and stated that the focus needs to be in broader terms instead of renewable fuels and recommended that the scope 

include all blending components. CWMA recommended that the item remain as an Informational Item and that 

FALS form a task group under their guidance to develop this proposal.

2010 NCWM Annual Meeting: The Committee received numerous letters (refer to Appendix E within the Report of 

the 95th National Conference on Weights and Measures [SP 1115, 2010]) and heard from fifteen stakeholders and 

industry representatives, supporting Section 3.15.3. Documentation for Dispenser Labeling Purposes that requires 

disclosure. Several participants expressed concerns with sections of the proposal. FTC has the authority to protect 

consumers, and they are considering requirements for product transfer documents. Several stakeholders indicated 

that they expect FTC to issue a proposed rule on biodiesel. The sections that are of concern to stakeholders are 

Section 3.15.4. Exemption (b) and (c), since they conflict with reporting of tax collections on biodiesel. The exact 

amount of the blend needs to be documented on the transfer document. The concern is when fuel is picked up from 

various locations and delivered; the actual amount of biodiesel is not documented. Currently blending at the 

terminal is not an issue. The L&R Committee agreed to allow time for the FALS to receive additional information 

and further discuss this item. 

2010 CWMA Interim Meeting: A representative from a Petroleum Marketers Association commented that 

disclosure sets the tone for a chain of events for biodiesel. It was important for disclosure to be provided all the way 

through the distribution process because of the potential for over-blending. He believes that it is not realistic for 

wholesale distributors to test for biodiesel due to the cost. H e supports the proposal with exception of the 

exemptions provided in Section 3.15.4. Exemption (b) and (c). An official agreed with this testimony. Another 

official commented that the current proposal follows the same format as the ethanol regulation. A petroleum dealer 

mentioned that, due to the expanded Renewal Fuels Standard (RFS), disclosure is needed in order to meet the 

mandates for blending. 

A representative with the NBB commented that this proposal needs further development by FALS. She believes 

that we have not heard from all segments of the industry regarding this proposal. She also expressed concern that 

there will be no benefit to consumers if the cost of the extra testing of fuel is being passed on to consumers. It was 

mentioned that there are quick testing methods available for determining biodiesel content in the field; although, 

some are more accurate than others. The NBB representative also stated that the FTC believes it is the responsibility 

of the blender to determine biodiesel content prior to blending. 

A producer mentioned that the disclosure proposal would require terminals to purchase equipment and to do 

additional testing. The producer is concerned about tank stratification and the need to change bills of lading as the 

content varies. Cost and manpower are major concerns for producers. A marketer provided testimony that it is 

more efficient for terminals to purchase testing equipment as opposed to requiring all downstream blenders to 

purchase testing equipment. He stated that changing bills of lading is only a software change. He believes that it is 

the blenders’ obligation to meet the law for labeling, and it is difficult if the biodiesel content is not disclosed. The 

NBB representative questioned how often marketers test. A marketer responded that they do not routinely test; 

since they rely on transfer documents to accurately disclose biodiesel content. A nother marketer stated that 

producers can control what goes into their tanks and questioned if producers know how much biodiesel is in each 

batch. A producer responded that for barrels received by water in Savannah, Georgia, the biodiesel content is only 

disclosed on Plantation pipeline shipments if it is more than 5 %. The CWMA recommended that the item remain as 

an Informational Item to be further developed by FALS.

2010 WWMA and SWMA Annual Meetings: A n industry representative spoke in support of keeping this item 

Informational and allowing FALS to further develop the requirements in light of the comments received. A n

industry representative stated that all shipping documents should show the exact blend of biodiesel. Both 

Associations recommended that the item remain as an Informational Item. 

2010 NEWMA Interim Meeting: The Committee received written comments from API. NEWMA recommended 

that the item remain as an Informational Item. 

2011 NCWM Interim Meeting: A member of both the FALS and L&R Committee reported that this item was 

debated during the FALS work sessions and a consensus could not be reached. It was agreed upon that a Biodiesel 

Disclosure Task Group be formed to further study this item. Mr. Howell, MARC-IV, and Mr. Bell, Echols Oil 

Company, Inc. will co-chair this Task Group. The Committee received five letters yet no additional comments were 

received in Open Hearings. The 2011 L&R Committee designated this item as an Informational Item. 

FALS reported that a smaller work group of its members plan to complete a report containing possible solutions and 

present it to FALS at the 2012 NCWM Interim Meeting in January. 

2011 NEWMA Annual Meeting: A consultant with the National Biodiesel Board (NBB) stated that a report is being 

prepared and will be ready for the 2011 Annual NCWM meeting. NEWMA recommended that the item remain as a 

Developing item.

2011 CWMA Annual Meeting: Mr. Ron Hayes, FALS Chairman and representative of Missouri, remarked that a 

WG was formed under FALS to develop new language. A petroleum representative opposed the item as written as 

it does not allow the blender to disclose what level blending has occurred. Another petroleum representative 

remarked that there are other implications beyond small percentages of biodiesel with other additives. It was agreed 

that as blender you should know exactly what you are getting, but it needs to be tested. The question is who is the 

responsible party for providing the test? The CWMA recommended that the item remain as a Developing item.

2011 NCWM National Meeting: Mr. Hayes reported that a Subcommittee under FALS has been formed to work out 

a compromise on the requirements and a report with solutions should be prepared for FALS at the 2012 NCWM

Interim Meeting.

2011 CWMA Interim Meeting: The NBB representative stated a task group was formed under the guidance of 

FALS to develop language. The Petroleum Marketers and Convenience Store of Iowa (PMCI) representative stated 

there were 137 biodiesel blenders in Iowa and the current proposed language is a real concern to blenders, especially 

the 5 % blenders. The marketers do not support an exemption for blends of 5 % or less on the product transfer 

documents. One official agreed and suggested removing the exemption for 5 % blends stating that if percentage is 

known it reduces the need for downstream testing. The NBB representative countered that testing adds a lot of cost 

before the product reaches the consumer and that 5 % biodiesel or less meets the ASTM D975 diesel fuel 

specification and there is no performance difference. She also stated the current proposed language may be the best 

compromise that can be achieved. The official reported that terminals in her state already certify how much 

biodiesel leaves the terminal. The NBB representative countered that biodiesel was developed as a fungible product 

and is a drop-in fuel. Further, fungibility issues dictate that we not disclose the exact biodiesel content. The PMCI 

representative stated that gallons of biofuel must be reported, and the language in Item 237-3 (refer to the Report of 

the 96th National Conference on Weights and Measures (SP 1125, 2011) is a compromise because his constituents 

did not have input into the exemption language. An energy company representative stated that Plantation Pipeline is 

saying diesel fuel may contain up to 5 % biodiesel. Therefore, batch certification would be required to determine 

content. Stratification is also a concern because even batch testing may not be indicative of the true content. The 

PMCI representative stated this issue is really about the Renewable Identification Number (RIN) credit and how 

they are bought and sold. The NBB representative stated that weights and measures are most concerned with 

making sure there is equity in the marketplace and that profitability in the marketplace is left up to the market. An 

official questioned where the burden of analysis lies and if the blender is making a profit then it is reasonable to 

expect the blender to bear the cost. FALS is currently gathering information on this item. CWMA recommended 

that the item remain as an Informational Item. 

2011 WWMA Annual Meeting: There were no comments heard. The Committee would like to get a 

recommendation from FALS before taking further action. WWMA recommended that the item remain as an 

Informational Item. 
L&R Committee 2013 Final Report

L&R - 59

2011 NEWMA Interim Meeting: It was agreed that any action taken should be consistent with other federal agency 

labeling. NEWMA recommended that the item remain as an Informational Item. 

2011 SWMA Annual Meeting: A representative of the NBB conveyed a message on behalf of the chair of FALS, 

that it will meet before the NCWM Interim Meeting and provide a report to FALS for the L&R Committee. SWMA

recommended that the item remain as an Informational Item. 

2012 NCWM Interim Meeting: FALS met and Mr. Bell and Mr. Howell, Task Group Co-Chairs provided a 

presentation on the updated data and study. They presented a written report to FALS on January 17, 2012. A plan 

was submitted for the activities of this Task Group for the next eighteen months. FALS recommended that this item 

remain as an Informational Item. The 2012 L&R Committee designated this item as an Informational Item.

2012 NEWMA Annual Meeting: There were no comments on this item. NEWMA recommended that the item 

remain as an Informational Item.

2012 CWMA Annual Meeting: Mr. Hayes remarked that Steve Howell and Sam Bell have written a white paper on 

this item and the paper will be posted on the NCWM website prior to the 2012 NCWM Annual Meeting. CWMA

recommended that the item remain as an Informational Item.

2012 NCWM Annual Meeting: Mr. Hayes, FALS Chairperson, reported that Mr. Bell and Mr. Howell gave a 

presentation to the Subcommittee, however; there was no consensus on how to move forward with this item.

2012 CWMA Interim Meeting: T he FALS Chairman reported that the WG did not reach a consensus and 

recommended withdrawing the item. A regulatory official asked if withdrawing the item would cause harm. 

Another stated that biodiesel marketers needed to know biodiesel content, and that the item should move forward as 

a Voting Item. The Iowa Petroleum Marketers representative said this is a state enforcement issue and the item 

should be withdrawn. He said that 16-CFR 306 does not address diesel. Iowa had already passed regulations for

this and the language in this item would not work in Iowa. Another official recommended moving forward as a 

Voting Item. A National Biodiesel Board representative said while NBB tries to remain neutral, that this language 

could have unintended consequences for states where biodiesel is not produced or marketed, resulting in 

unnecessary testing for biodiesel content. A regulatory official stated that biodiesel is present in states that do not

produce or market it. She also stated that some consumers don’t want biodiesel content. NIST Handbook 130 is 

currently consistent with FTC regulations, and NBB recommends Withdrawing this item. FTC reviewed this issue 

and did not support further disclosure of biodiesel content. Many states do not produce biodiesel, and many states 

that do produce biodiesel already have state regulations in place that would pre-empt NCWM standards. The work 

group has attempted for several years to reach consensus and was unable to do s o. For these reasons, CWMA 

recommended that the item be Withdrawn.

2012 WWMA Annual Meeting: Ms . Rebecca Richardson (NBB) remarked that she heard Mr. Hayes, FALS 

Chairperson, inform CWMA this fall that FALS could not be agree on alternate language and recommended this 

item be Withdrawn. The Committee would like to get an update from FALS at the 2013 NCWM Interim Meeting. 

WWMA recommended that the item be an Informational Item.

2012 SWMA Annual Meeting: An industry representative from the National Biodiesel Board (NBB) commented 

that since this item was introduced in 2010, both the NCWM L&R Committee and the Fuels and Lubricants 

Subcommittee assigned this issue to a smaller work group co-chaired by Mr. Steve Howell and Mr. Sam Bell. There 

have been several concerns expressed during the vetting of this proposal, and ultimately the industry could not come 

to a consensus on the proposed language or any alternative. In fact, considering oral testimony and comments from 

the work group, the proposed language, which was a compromise from the original submission, was less desirable 

among fuel producers, marketers, and pipeline representatives. Since the proposed language was introduced, 

technology for the rapid analysis of biodiesel blends has become more sophisticated, and there are more tools to 

determine accurate biodiesel blends in real time. Anyone who wishes to blend biodiesel has the ability to determine 

the blend they are starting with before they add more. Since the NBB has concerns about negative, unintended 

consequences from this proposed new disclosure requirement, and considering the industry could not come to 

consensus on national model language, NBB’s recommendation is that states need to determine individually whether 

or not local conditions and regulations make it necessary to further disclose biodiesel blends below 5 % within their 
L&R Committee 2013 Final Report

own markets. Therefore, the NBB recommends that this proposal be Withdrawn. A letter to FALS on the task 

group recommendation will be provided before the NCWM Interim Meeting. The letter will include a 

recommendation that the Task Group be disbanded. A state official recommended the item be either Withdrawn or

made a Voting Item, since the item has been on the agenda since 2010. The Committee recommended that the item 

be retained as Informational until a recommendation is received from FALS. SWMA recommended that the item be 

an Informational Item.

2012 NEWMA Interim Meeting: T he NBB gave an update. There is no consensus on the issue. N BB 

recommended that item be Withdrawn consistent with FALS position. NEWMA recommended that the item be 

Withdrawn.

2013 NCWM Interim Meeting: Sam Bell who co-chairs of a task group under stated they could not reach consensus 

on this item. FALS recommended to the Committee that this item be Withdrawn in its entirety. The Committee 

concurs with FALS’ recommendation to Withdraw this item. 

2013 NEWMA and CWMA Annual Meetings: Both associations concur that this item should be Withdrawn.

2013 NCWM Annual Meeting: The Committee accepted the recommendation of the FALS to Withdraw this item.

Additional letters, presentations and data may have been part of the Committee’s consideration. Please refer to 

Appendix G in the Report of the 97th National Conference on Weights and Measures [SP 1160, 2012] to review

Background/Discussion: 

The level of confusion for consumers fueling vehicles continues to grow with the introduction of new fuels in the 

marketplace. This amendment would ensure proper delivery of the selected product and reduce the potential of 

mis-fueling vehicles. Missouri and other states have received complaints from consumers who have fueled their 

vehicles with inappropriate products. At this time, practically all gasoline dispensers nationwide do not comply with 

NIST Handbook 44, Section UR.3.2. or S.1.6.4.2.(a) as they do not display the product identity (i.e., gasoline). 

2012 CWMA Interim Meeting: One official supported the item, but recommended that FALS review the language 

so that stakeholders on that Subcommittee have an opportunity to review the language. An ethanol industry 

representative also supported the item, stating that the language should be reviewed by industry stakeholders. 

CWMA supported the item; recommending FALS review. CWMA forwarded the item to NCWM recommending it 

as an Informational Item.
L&R Committee 2013 Final Report

2012 SWMA Annual Meeting: T he Committee

heard opposition from an industry member and 

support from a regulatory official. SWMA forwarded

the item to NCWM, recommending it as an 

Informational Item.

2012 NEWMA Interim Meeting: Members 

expressed concern for additional clutter on retail 

dispensers. There was also concern that nozzles 

could end up on products that do NOT match the 

product being dispensed. One member indicated that 

the consumer has some responsibility for making the 

proper product choice when at the dispenser. 

NEWMA forwarded the item to NCWM

recommending it as an Informational Item.

2013 NCWM Interim Meeting: Ron Hayes, FALS Chairperson, remarked that there is no support in FALS for this 

item and FALS is recommending it be Withdrawn. The Committee concurs with FALS and Withdrew this item.

2013 CWMA and NEWMA Annual Meetings: Both Associations recommended this item be Withdrawn.

2013 NCWM Annual Meeting: The Committee recommended this item be Withdrawn.

Background/Discussion: 

The current wording in NIST Handbook 130 related to fuels restricted to use in Flex Fuel Vehicles should be 

reviewed. Input gathered from the regional meetings and other stakeholders will be utilized by FALS to develop 

recommended modifications to NIST Handbook 130. 

2011 CWMA and NEWMA Interim Meeting: There were no comments. CWMA and NEWMA forwarded the item 

to NCWM recommending it as a Developing Item while FALS continues its work. 

2011 WWMA Annual Meeting: WWMA forwarded the item to NCWM recommending it as an Informational Item

while FALS continues its work.

2011 SWMA Annual Meeting: Mr. Chuck Corr, Chair of the Task Group (TG) under the FALS, gave a presentation 

on the topic. FALS TG identified several areas where stakeholder input is needed to propose updates to NIST 

Handbook 130 and to reflect new language in ASTM D5798. No comments were made during the hearing. FALS 

is expected to have a r ecommendation for the Interim Meeting. SWMA forwarded the item to NCWM 

recommending it as a Developing Item.

L&R - 65

2012 NCWM Interim Meeting: The Committee received updates on the TG’s progress. Mr. Corr will lead an effort 

to get regional input on a transition and implementation date. The 2012 L&R Committee designated this item as an 

Informational Item. 

2012 NEWMA Annual Meeting: There were no comments. NEWMA recommended that the item remain as an 

Informational Item.

2012 CWMA Annual Meeting: Mr. Corr gave a presentation on “Flex Fuel Task Force Update” (Flex Fuel Task 

Group Update). This presentation noted that ASTM standards D7794-12 and D5798-11 cover the standard for a full 

range of ethanol concentrations. Several commented that the 51 % to 83 % range is too broad. A regulatory official

was concerned with blends at the pumps. They can blend and percentage they choose. A stakeholder remarked that 

consumers are concerned with price and miles per gallon (MPG) and may not have enough knowledge in regards to 

blends. Another stakeholder remarked that ASTM 5798 is at the terminal and the Conference needs to address this 

issue. CWMA recommended that the item remain as an Informational Item and that FALS continues its 

development. 

2012 NCWM Annual Meeting: Mr. Corr reported on behalf of FALS TG that approximately 18 areas of NIST 

Handbook 130 have been identified where modifications may be needed. A stakeholder voiced full support of the 

TG efforts. Mr. Corr’s group will report again at the 2013 NCWM Interim Meeting.

2012 CWMA Interim Meeting: The FALS Task Group chair gave a presentation and would like to present an item 

to the NCWM L&R that would be ready for voting status at the 2013 NCWM Annual Meeting. He asked for input 

from regulators on a generic name for flex fuel vehicle fuel, names for individual blends, and labels for blends. The 

CWMA supports this item and recommends that it remain an Information Item for further development by the FALS 

TG. 

2012 WWMA Annual Meeting: Mr. Corr provided an update on behalf of FALS. Mr. Corr stated that information 

will be fully developed and released prior to the 2013 NCWM Interim Meeting. The Committee would like to 

review that information. WWMA recommended that the item be an Informational Item.

2012 SWMA Annual Meeting: Mr . Corr commented as chair of the Fuels and Lubricants Subcommittee Task 

Group that the group is working on language to reflect to reflect the new ASTM D7794 and recently modified 

D5798 standards for fuels restricted to flex fuel vehicles. It should be available for review at the Interim. 

Mr. Russ Lewis (Marathon Petroleum) gave a presentation in support of the proposal, taking into account the 

recently modified ASTM D5798 “Specifications for Ethanol Fuel Blends for Flexible Fuel Automotive Spark 

Ignition Engines”. Russ provided a copy of newly proposed language to the TG for consideration. SWMA 

recommended that the item be an Informational Item.

2012 NEWMA Interim Meeting: NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: Mr. Corr provided an update of the language changes he is recommending for 

addressing the full range of fuels restricted to flex fuel vehicles in NIST Handbook 130. Mr. Corr commented that 

no feedback has been provided to him from stakeholders and states concerning the language changes. Mr. Corr also 

remarked that the FALS has also not reviewed and discussed the proposed changes. The Committee recommended 

this as an Informational Item so that interested parties can provide comments.

2013 CWMA and NEWMA Annual Meetings: Both Associations support the on-going work being done by the TG 

on this item. Both Associations recommend this move forward as an Informational Item. 

2013 NCWM Annual Meeting: M r. Corr provided initial language changes for a Uniform Regulation for the 

Method of Sale, Section 2.30. E85 Fuel Ethanol Flex Fuel Blends. This language has been placed under the Method 

of Sale of Commodities and appears as Item 232-6.

260 NIST HANDBOOK 133

260-1 V Section 2.3.8. Moisture Allowance – Pasta Products

(This item was adopted.)

Source: 

Southern Weights and Measures Association (2010)

Purpose: 

Establish a moisture allowance for macaroni, noodle, and like products (pasta products). 

Item Under Consideration: 

Amend NIST Handbook 133 as follows: 

2.3.8. Moisture Allowances

When no predetermined allowance is found in NIST Handbook 133, the potential for moisture loss must be 

considered. I nspectors should follow their jurisdiction’s guidance for making their determination on an 

acceptable moisture allowance.

(Added 2010)

If the product tested is subject to moisture loss, provide for the moisture allowance by following one of the two 

procedures listed below.

2.3.8.1. Applying Moisture Loss before Determining Package Errors

1. Determine the percent value of the moisture allowance if the product is listed below. (See Table 2-3. 

“Moisture Allowances”)
L&R Committee 2013 Final Report

L&R - 67

Table 2-3.

Moisture Allowances 

Verifying the labeled net 

weight of packages of:

Moisture 

Allowance is: Notes

Flour 3 %

Dry pet food 3 % 

Dry pet food means all extruded dog and cat foods and baked 

treats packaged in Kraft paper bags and/or cardboard boxes with 

a moisture content of 13 % or less at time of pack.

Pasta Products 3 % 

Pasta products means all macaroni, noodle, and like products 

packaged in Kraft paper bags, paperboard cartons, and/or 

flexible plastic bags with a moisture content of 13 % or less at 

the time of pack.

Borax See 

Section 2.4.

Wet Tare Only1

Fresh poultry 3 % Fresh poultry is defined as poultry above a temperature of − 3 °C 

(26 °F) that yields or gives when pushed with the thumb.

Franks or hot dogs 2.5 %

Bacon, fresh sausage, and 

luncheon meats 0 %

For packages of bacon, fresh sausage, and luncheon meats, there 

is no moisture allowance if there is no free-flowing liquid or 

absorbent material in contact with the product and the package is 

cleaned of clinging material. L uncheon meats are any cooked 

sausage product, loaves, jellied products, cured products, and any 

sliced sandwich-style meat. This does not include whole hams, 

briskets, roasts, turkeys, or chickens requiring further preparation 

to be made into ready-to-eat sliced product. W hen there is no 

free-flowing liquid inside the package and there are no absorbent 

materials in contact with the product, Wet Tare and Used Dried 

Tare are equivalent.

1

Wet tare procedures must not be used to verify the labeled net weight of packages of meat and poultry packed at an 

official United States Department of Agriculture (USDA) facility and bearing a USDA seal of inspection. The 

Food Safety and Inspection Service (FSIS) adopted specific sections of the 2005 4th edition of NIST HB 133 by 

reference in 2008 but not the “Wet Tare” method for determining net weight compliance. FSIS considers the freeflowing liquids in packages of meat and poultry products, including single-ingredient, raw poultry products, to be 

integral components of these products (see Federal Register, September 9, 2008, [Volume 73, Number 175] [Final 

Rule – pages 52189-52193]).

(Amended 2010 and 2013) 

Note: There is no moisture allowance when inspecting meat and poultry from a USDA inspected plant when Used 

Dry Tare and “Category A” sampling plans are used.
L&R Committee 2013 Final Report

L&R - 68

Note: For the Wet Tare Only section of Table 2-3, free-flowing liquid and liquid absorbed by packaging materials 

in contact with the product are part of the wet tare.

(Added 2010)

2. To compute moisture allowance, multiply the labeled quantity by the decimal percent value of the 

allowance. Record this value in Box 13a.

Example: 

Labeled net quantity of flour is 907 g (2 lb)

Moisture Allowance is 3 % (0.03)

Moisture Allowance = 907 g (2 lb) x 0.03 = 27 g (0.06 lb)

3. If the Moisture Allowance is known in advance (e.g., flour, pasta products and dry pet food), it can be 

applied by adjusting the Nominal Gross Weight used to determine the sample package errors. T he 

Moisture Allowance in Box 13a is subtracted from the Nominal Gross Weight to obtain an Adjusted 

Nominal Gross Weight which is entered in Box 14. The Nominal Gross Weight is defined in 

Section 2.3.6.1. as the sum of the Labeled Weight and the Average Tare Weight from Box 13. 

Example: 

Use a Labeled Weight of 907 g (2 lb) and an Average Tare Weight of 14 g (0.03 lb) 

The calculation is:

Labeled Net Quantity of Contents 907 g (2 lb) + Average Tare Weight 14 g (0.03 lb) = 921 g 

(2.03 lb) – Moisture Allowance 27 g (0.06 lb) = Adjusted Nominal Gross Weight of 894 g 

(1.97 lb)

This result is entered in Box 14.

4. Determine package errors by subtracting the Adjusted Nominal Gross Weight from the Gross Weights 

of the Sample Packages.

Example: 

The calculation is:

Gross Weight of the Sample Packages – Adjusted Nominal Gross Weight = Package Error

Note: When the Nominal Gross Weight is adjusted by subtracting the Moisture Allowance value(s) the 

Maximum Allowable Variation (s) is not changed. This is because the errors that will be found in the 

sample packages have been adjusted by subtracting the Moisture Allowance (e.g., 3 %) from the Nominal 

Gross Weight. T hat increases the individual package errors by the amount of the moisture allowance 

(e.g., 3 %). If the value(s) of the MAV(s) were also adjusted it would result in doubling the allowance. 

MAV is always based on the labeled net quantity.

(Added 2010)

2.3.8.3. Moisture Allowance Gray Area

When the average error of a lot of fresh poultry, franks, or hot dogs, pasta products is minus but does not 

exceed the established “moisture allowance” or “gray area,” contact the packer or plant management personnel 

to determine what information is available on the lot in question. Questions to the plant management 

representative may include:

• Is a quality control program in place?
L&R Committee 2013 Final Report

L&R - 69

• What information is available concerning the lot in question? 

• If net weight checks were completed, what were the results of those checks?

• What adjustments, if any, were made to the target weight?

Note: If the plant management has data on the lot, such data may help to substantiate that the “lot” had met the 

net content requirements at the point of manufacture.

This handbook provides “moisture allowances” for some meat and poultry products, flour, pasta products, and 

dry pet food. These allowances are based on the premise that when the average net weight of a sample is found 

to be less than the labeled weight, but not by an amount that exceeds the allowable limit, either the lot is 

declared to be within the moisture allowance or further investigation can be conducted.

Reasonable variations from net quantity of contents caused by the loss or gain of moisture from the package are 

permitted when caused by ordinary and customary exposure to conditions that occur under good distribution 

practices. If evidence is obtained and documented to prove that the lot was shipped from the packaging plant in 

a short-weight condition or was distributed under inappropriate or damaging distribution practices, appropriate 

enforcement action should be taken.

Background/Discussion: 

Studies indicate that moisture loss for pasta products is reasonably predictable over time. Pasta exhibits consistent 

moisture loss in all environments and packaging, which can vary more than 4 % due to environmental and 

geographic conditions. Although it eventually reaches equilibrium with the surrounding atmosphere, because it is 

hygroscopic, this balance does not occur until long after packaging and shipping.

2010 Interim Meeting: The Committee heard support for this item from industry and stakeholders. This item would

amend the Moisture Allowance Table in NIST Handbook 133 giving pasta a 3 % moisture allowance. T he 

Committee reviewed the submitted study (refer to the Report of the 95th National Conference on Weights and 

Measures [SP 1115, 2010]). The 2010 L&R Committee designated this item as a Voting Item. 

2010 NEWMA Annual Meeting: A representative of the pasta industry gave the group an explanation of the item 

and expressed support for this item as written. NEWMA also supported this item.

2010 CWMA Annual Meeting: A representative from the National Pasta Association (NPA) stated the data 

supports the 3 % moisture allowance. A n official commented that testing in their state does not support the 

proposal. A n industry representative stated that guidance is needed for an established moisture allowance and 

currently there are no guidelines to establish the moisture loss percentage.

2010 NCWM Annual Meeting: A representative for the NPA spoke on behalf of the proposal. This item would

allow for a specific moisture loss percentage to be taken. Inspectors would have a specific number that they can 

apply to the pasta product. Representatives of several pasta companies spoke in support of this item stating that it is 

consistent with numerous studies that have been done. An official opposed this item since pasta is known to have 

moisture loss due to the type of product it is. He further explained that applying a blanket 3 % moisture loss does 

not make sense, what may be good in Florida may not be good in New Mexico. Another official stated that applying 

the 3 % does not stop an inspector from going into a distribution or point of pack to inspect; especially if the 

inspectors believe the packer is under filling packages. He urged that this proposal be supported to provide a tool. 

Another official voiced support because it is important to recognize guidelines for consideration. A pasta 

association representative also agreed that this work goes back a co uple of decades and several studies were 

provided for consideration. Another representative explained that they pack to net weight. Pasta contains 10 % to 

13 % moisture; if the moisture standard is lowered the product falls apart along with the product quality. There was 

a split vote on this item at the 2010 Annual Meeting, and it was returned to the Committee. 

2010 CWMA Interim Meeting: An official provided information regarding informal testing of pasta products in 

their state. The concern is that pasta can gain moisture as well as lose moisture; therefore, they oppose a national 
L&R Committee 2013 Final Report

L&R - 70

moisture allowance for pasta products. It was further explained that moisture loss/gain seems to be dependent upon 

the type of packaging used. This official also commented that product is no longer warehoused for long periods of 

time, and it is mostly in climate controlled stores, which would prevent the need for a moisture allowance. Another 

official agreed that a n ational standard may not be appropriate due to humidity differences from state to state. 

CWMA recommended that the item be Withdrawn. 

2010 WWMA Annual Meeting: An official expressed support for adopting a 3 % moisture allowance for pasta 

citing the significant work done and data provided by the NPA. The Committee recommended that any additional 

data from studies be provided for review. WWMA recommended that the item remain as a Voting Item. 

2010 SWMA Annual Meeting: There were no comments on this item. SWMA recommended that the item be 

Withdrawn; however, if further studies are developed, then this should be taken into consideration.

2010 NEWMA Interim Meeting: Attendees expressed strong reservations about this proposal. Comments were 

heard regarding industry practices in regards to moisture loss when packing and if there is a n eed to codify the 

moisture loss allowance at all. A member commented that if this proposal passed, other industries would now 

approach the Conference and ask for specific moisture allowances for their products. NEWMA recommended that 

the item be Withdrawn. 

2011 NCWM Interim Meeting: An overview was presented by the NPA regarding the history and studies that have 

been performed in regard to moisture loss of pasta. Pasta is a hygroscopic product and changes in moisture content 

in the product may occur in the package due to atmospheric changes (refer to Appendix I, Report of the 96th 

National Conference on Weights and Measures [SP 1125, 2011]). Hot, dry, and air conditioned store environments 

have less humidity and will pull moisture from the product. Conversely, in tropical, wet and high humidity 

environments (seldom seen in U.S. stores) the product will pull moisture in. According to Ms. Hoover (American 

Italian Pasta Company), companies do pack to the law and have documented weight control programs. The 2011

L&R Committee designated this item as a Voting Item. 

2011 NCWM Annual Meeting: T he NPA gave a presentation with background information and a brief legal 

overview on moisture loss. NPA also distributed a page with frequently asked questions and a follow-up study 

(refer to Appendix I, Report of the 96th National Conference on Weights and Measures [SP 1125, 2011]) that 

occurred in 2006 - 2007 that shows a 2.5 % to 5 % moisture loss. Pasta consists of flour and water. Handbook 133

stipulates a 3 % moisture allowance for flour. P asta is packaged in either breathable film or paperboard cartons. 

This allows for the pasta to breathe and not mold. The industry is requesting that this proposal be adopted by the 

Conference to give officials the guidance that is needed when performing inspections. On a split Vote this item was 

returned to the Committee. 

2011 CWMA Interim Meeting: A n industry representative stated that a uniform procedure for moisture loss is 

needed. Although difficult, we can develop a surrogate that can be easily used by manufacturers and easily verified 

by weights and measures and recommended this item be Withdrawn. The Committee disagreed and believes that

moisture loss is a l egitimate issue and deserves consideration by NCWM. CWMA recommended that the item 

remain as a Voting Item. 

2011 WWMA Annual Meeting: A state official requested additional information concerning good manufacturing 

and distribution processes. The Committee firmly believed that enough data had been established by industry to 

address questions regarding moisture allowances with pasta and pasta products. WWMA recommended that the 

item remain as a Voting Item. 

2011 NEWMA Interim Meeting: NEWMA continued to oppose this item. NEWMA recommended that the item be 

Withdrawn. 

2011 SWMA Annual Meeting: N o comments were heard. T he Committee noted that it appears as if proper 

protocol has been followed by the pasta industry. If states do not support the item, SWMA recommends that they 

provide the reasons so their issue(s) can be addressed. SWMA recommended that the item remain as a Voting Item.

2012 NCWM Interim Meeting: The Committee reviewed documents received from the NPA. A representative with 

the American Italian Pasta Company supported the language as presented. An official who has an active package 

inspection program remarked that a significant amount of data has been provided by the NPA. The 2012 L&R 

Committee designated this item as a Voting Item. 

2012 NEWMA Annual Meeting: Ms. Jayne Hoover (American Italian Pasta Company) gave a presentation on the 

development of this topic and the extensive national testing and data collection which was done. One member 

indicated that it was a good objective and did not see a reason to oppose it. Several others voiced their historical 

opposition to moisture allowance. On a split vote, NEWMA recommended that the item remain as a Voting Item.

2012 CWMA Annual Meeting: A representative from the NPA and American Italian Pasta Company addressed the 

top five frequently asked questions which are: 1) 3 % gray area (gray area is not a tolerance), 2) current data on 

product (2006 - 2007 study of over 700 samples), 3) why 3 %, 4) what causes variability (there are over 500 shapes 

of pasta and 3000 SKUs), and 5) regulatory standardization. Three regulatory officials spoke in opposition to the 

item. Several others spoke in favor, commenting that officials are required to recognize reasonable moisture loss

and pasta rehydrates during cooking so there is no loss to the consumer. One regulator asked for clarification on

why moisture loss appears to level out at six months. The NPA representative explained that different pastas have 

different moisture loss due to their shapes and size. CWMA recommended that the item remain as a Voting Item.

2012 NCWM Annual Meeting: Ms. Hoover provided an overview on gray area, current data, and variability. She

stressed the need for uniformity in the marketplace. A nother pasta representative remarked that Congress 

established that it is important to keep in mind the gray area. The gray area is not a tolerance and moisture loss does 

not cause the product to be short weight. Several regulatory officials spoke in support of this item. Two spoke in 

opposition, noting that moisture loss should be dealt with on a case-by-case basis. O n a split vote, the item was 

returned to the Committee. 

2012 CWMA Interim Meeting: A regulatory official recommended withdrawing the item. It has been voted on 

twice at NCWM, and both votes were split votes. Another recommended it be a Voting Item because some states 

did not realize that abstaining from the vote was tantamount to a no vote. No CWMA officials planned to change 

their vote. Another official recommended that it move forward as a Voting Item, stating that the industry had 

submitted a complete proposal that justified the moisture allowance. The item was fully developed with supporting 

data that justified the moisture allowance. Those states that abstained in the 2012 NCWM meeting should be given 

an opportunity to vote on this item. CWMA supported the item and recommended that the item be a Voting Item.

2012 WWMA Annual Meeting: Five regulatory officials commented in support of the item. NPA has met all 

requests to provide documented data that supported initial studies on moisture loss. The data demonstrated that a 

3 % moisture allowance is appropriate. Under federal law moisture loss must be recognized and adoption of this 

item would provide a moisture allowance for inspectors when testing pasta products. Comments stressed that a 

moisture allowance should be adopted to provide guidance to the pasta industry and to regulatory officials regarding 

package content compliance testing and enforcement. No evidence or data has been presented at any of the regional 

associations and NCWM meetings to contradict NPA’s data presented. The Committee recognized the cooperation 

by the pasta industry members to comply with NCWM’s request to demonstrate the appropriateness of the proposed 

3 % moisture allowance. The Committee supported the item, but expressed concern that it has not advanced 

because of a split vote for several years. The Committee suggested that the NCWM L&R Committee make this a 

priority item for the Moisture Allowance Work Group. In addition to the NPA study data, the Committee would 

have preferred an independent study from outside sectors. The Committee recognizes that additional data and 

studies may be available. If there is other data available that contradicts or supports NPA’s data, individuals are 

urged to submit it to the NCWM for consideration. WWMA recommended that the item be a Voting Item.

2012 SWMA Annual Meeting: The Committee believed the pasta industry has presented the necessary data needed 

by the NCWM to make a decision. SWMA recommended that the item be a Voting Item.

2012 NEWMA Interim Meeting: NEWMA members stated that sufficient work has been done on this topic and that 

more than enough data has been submitted to support the proposal. NEWMA members who had previously opposed 

the item stated that it now has their support. NEWMA recommended that the item be a Voting Item.
L&R Committee 2013 Final Report

L&R - 72

2013 NCWM Interim Meeting: Ms. Maile Hermida (Hogan Lovells, US, LLP) remarked that the NPA supports this 

item due to the strong underlying data that supports the proposal. Mr. Kurt Floren (Los Angeles County, California) 

commented that this item remained on the agenda due to a split vote at the 2012 NCWM Annual Meeting. Under 

federal law you must allow for reasonable moisture loss. Mr. Floren would like to hear the reasons as to why states 

oppose this item. Several states spoke up in support of the item. The Committee recommends this as a Voting item.

2013 CWMA Annual Meeting: A state regulator provided data on a study performed by his state which 

corroborates evidence that a moisture reduction of 3 % is reasonable. The Committee believes the data presented by 

industry and the state supports the 3 % grey area. The Committee recommends this be a Voting Item.

2013 NEWMA Annual Meeting: The Committee believes that sufficient work has been done and supports this item 

as a Voting Item.

2013 NCWM Annual Meeting: There was testimony heard during open hearings stating there is support to move 

this item forward. The Committee recommended the item be presented for a Vote as shown in the Item Under 

Consideration.

Additional letters, presentations and data may have been part of the Committee’s consideration. Please refer to

260-2 V Section 3.10. Animal Bedding

This appeared as Voting Item 260-2 in the Committee Reports for the 98th Annual Meeting (NCWM 

Publication 16, 2013). At the 2013 NCWM Annual Meeting the Committee modified the status of this item to 

a Developing Item. This item is now identified as Item 270-6.

260-3 W Gravimetric Testing of Printer Ink and Toner Cartridges

(This item was withdrawn.)

Source: 

WWMA (2013)

Purpose: 

Provide a test procedure in NIST Handbook 133 for gravimetric testing of printer ink and toner cartridges.

Item Under Consideration: 

None. 

Background/Discussion: 

The Laws and Regulations Committee received a proposal in 2010 to create a uniform method of sale for printer ink 

and toner cartridges. See the related item in the 232 Series of this report for more detail and background discussion.

A Task Group was formed to address the method of sale, but was unable to reach consensus. In 2012, the Task 

Group was replaced with a new one that was charged to develop Handbook 133 gravimetric test procedures to verify 

net contents of ink and toner cartridges. The Committee agreed to keep the original Method of Sale item as an 

Informational Item until the second Task Group completes its recommendations. 

2012 WWMA Annual Meeting: Mr. Paul Jeran expressed concern with the concept of providing a tare weight on 

package labels because his company has over 30 million items and believes the test method under consideration may 

not be appropriate. In reviewing the background discussion of the 232 Series Method of Sale Item, the Committee

recommends that NCWM give careful consideration to industry concerns. W WMA recommended that the item 

remain as a Developing Item. 
L&R Committee 2013 Final Report

L&R - 73

2013 NCWM Interim Meeting: Ms. Judy Cardin, Printer Ink and Toner Cartridge Gravimetric Package Testing 

Task Group Chair provided a presentation on the work of the task group (refer to Item 232-4). Ms. Cardin also 

provided a marketplace survey that reflected “count” was the most common quantity statement being used. It was 

requested of industry the feasibility to place the tare weight on cartridges. This was not practicable due to cartridge 

parts being manufactured domestically and internationally and may not always be made of the same material. The 

presentation also reflected an in-house test using a gravimetric procedure. It was determined by the Task Group that 

there is not a practical test procedure. The L&R Committee Withdrew this item in its entirety.

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to

260-4 V Section 4.3. Paper Plates and Sanitary Paper Products

This appeared as Voting Item 260-4 in the Committee Reports for the 98th Annual Meeting (NCWM 

Publication 16, 2013). At the 2013 NCWM Annual Meeting, the Committee modified the status of this item to 

a Developing Item and is now identified as Item 270-5.

270 OTHER ITEMS – DEVELOPING ITEMS

The Committee Chair has the discretion as to whether or not to take comments on Developing Items during 

Committee open hearings based on factors such as the amount of time remaining to cover Committee Agenda item. 

270-1 D Fuels and Lubricants Subcommittee

Source: 

The Fuels and Lubricants Subcommittee (2007)

Purpose: 

Update the Uniform Engine Fuels, Petroleum Products, and Automotive Lubricants Regulation in NIST 

Handbook 130 including major revisions to fuel ethanol specifications. Another task will be to update the Basic 

Engine and Fuels, Petroleum Products, and Lubricants Laboratory Publication.

Item Under Consideration: 

This item is under development. A ll comments should be directed to Mr. Ronald Hayes, FALS Chair, at 

(573) 751-4316, ron.hayes@mda.mo.gov, or Mr. David Sefcik, NIST Technical Advisor at (301) 975-4868, 

dsefcik@nist.gov. 

Background/Discussion: 

The Subcommittee met on January 24, 2007, at NCWM Interim Meeting to undertake a review of a n umber of 

significant issues related to fuel standards. Their first project was to undertake a major review and update of the 

Uniform Engine Fuels, Petroleum Products, and Automotive Lubricants Regulation in NIST Handbook 130. The 

Subcommittee also met at the 2007 NCWM Annual Meeting and continued its work on a number of items in 

addition to preparing a major revision of the Fuel Ethanol Specifications.

An additional project will be to update and possibly expand the Basic Engine Fuels, Petroleum Products, and 

Lubricants Laboratory Publication. The Subcommittee will undertake other projects as time and resources permit.

Additional background/history, letters, presentations, and data may have been part of the Committee’s consideration.

270-2 D Packaging and Labeling Subcommittee

Source: 

Packaging and Labeling Subcommittee (2011)

Purpose: 

Provide notice of formation of a new Subcommittee reporting to the L&R Committee.

Item Under Consideration: 

None

Background/Discussion: 

2011 NCWM Interim Meeting: The PALS met for the first time to discuss ongoing issues and agenda items in 

regards to packaging and labeling regulations. There were 11 attendees that represented industry, state and county 

regulatory officials, and the NIST Technical Advisor. 

The mission of PALS is to assist the L&R Committee in the development of agenda items related to packaging and 

labeling. T he Subcommittee will also be called upon to provide important and much needed guidance to the 

regulatory and consumer packaging communities on difficult questions. P ALS will report to NCWM L&R

Committee. The NIST Technical Advisor reported that FTC will do a review of FPLA in 2013. The 2011 L&R 

Committee designated this item as a Developing Item and assigned its development to PALS.

2011 CWMA Interim Meeting: The PALS Chair stated the goal is to be active before the 2012 NCWM Interim 

meeting and stated there is a need to prioritize labeling issues. No action was needed. CWMA recommended that 

the item remain as a Developing Item. 

2012 NCWM Interim Meeting: P ALS met to discuss its formation and strategy. The NCWM Chairman will 

appoint eight voting members on the Committee to consist of four regulatory officials (one from each region) and 

four from industry (two retailers and two manufacturers). M r. Christopher Guay (Procter and Gamble), PALS 

Chair, reported that work will be done through webinar meetings to be held approximately four times a year. PALS 

members will be responsible for providing updates at their regional meetings and to seek input into issues. 

Mr. Guay added that PALS will be developing proposals and providing guidance and recommendations on existing 

proposals as assigned by the NCWM L&R Committee. He also stressed the need and importance of having key 

federal agencies (FDA, FTC, and USDA) participating. The NIST Technical Advisor commented that FTC 

announced that they will review the FPLA in 2013. The 2012 L&R Committee designated this item as a Developing

Item and assigned its development to PALS.

2012 NCWM Annual Meeting: Mr. Guay reported the Subcommittee is considering further development of the 

following items:

• Additional Net Content Declarations on the Principal Display Panel – Package net contents are most 

commonly determined by the product form, for example, solid products are labeled by weight and liquid 

products are labeled by volume. S emi-solid products such as pastes, creams and viscous liquids are 

required to be labeled by weight in the United States and by volume in Canada. 

• Icons in Lieu of Words in Packaged labeled by Count – Can a clear and non-misleading icon take the 

place of the word “count” or “item name” in a net content statement? While existing Federal regulation 

requires regulatory label information to be in “English,” the increasing presence of multilingual labels and 

the growing diversity of the U.S. population suggest more consumers are served with a cl ear and nonmisleading icon. 

• Multilingual Labels 

• Multipacks and Bundle Packages – The net content statements for multipacks and bundled packages of 

individually labeled products can be different based on the approach used to calculate them. The difference 
L&R Committee 2013 Final Report

L&R - 75

is the result of the degree of rounding for dual inch-pound and metric declarations. Using two apparently 

valid but different methods can yield one net content statement result that provides more accuracy between 

the metric and inch-pound declarations and a different net content result, which is consumer friendly. 

2012 SWMA Annual Meeting: Mr. Guay stated Item 231-1 has been assigned to PALS for a recommendation. 

PALS is working on a series of principles and recommendations regarding claims and statements made on packages 

outside of quantity statement (i.e., supplemental, quality, and performance claims) on what is appropriate and what 

is not. P ALS will recommend that Item 231-1 be Withdrawn. P ALS is also looking at whether icons are 

appropriate as part of a quantity statement and how labeling of products with multilingual labels can be simplified. 

SWMA recommended that the item remain as a Developing Item.

2013 NCWM Interim Meeting: Mr. James Kohm (Director of Enforcement at the Federal Trade Commission 

[FTC]), briefed NCWM on the goals and objectives of FTC. Mr . Kohm gave a general overview of the Fair 

Packaging and Labeling Act (FPLA) and announced that it is under review in 2013. 

Mr. Guay provided an update on the action of PALS. PALS will be focusing on best practice principles for the 

various quantity and quality statements seen in the marketplace. PALS will also continue to work on the items 

addressed at the 2012 Annual Meeting.

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to

270-3 D Moisture Allowance Task Group (MATG)

Source: 

Moisture Allowance Task Group (2012)

Purpose: 

Provide notice of formation of a new Task Group reporting to the Committee. T his Task Group will provide 

additional guidance for making moisture allowances for products not listed in NIST Handbook 133. 

Item Under Consideration: 

None

Background/Discussion: 

2012 NCWM Interim Meeting: Ms. Judy Cardin, Committee Chair, will be requesting that the NCWM Board of 

Directors form a new Task Group to review moisture allowance. The 2012 L&R Committee designated this item as 

a Developing Item.

2012 NCWM Annual Meeting: Mr. Kurt Floren (Los Angeles County, California) announced that he will Chair the 

Moisture Allowance Task Group.

2012 WWMA Annual Meeting: M r. Floren remarked that he is actively seeking individuals with expertise in 

moisture allowance. WWMA recommended that the item remain as a Developing Item.

2012 SWMA Annual Meeting: The Committee supported the formation of the Moisture Loss Work Group. SWMA 

recommended that the item remain as a Developing Item.

2013 NCWM Interim Meeting: Kurt Floren, MATG Chairperson announced that he is still seeking a representative 

from each region for the MATG. H e would prefer to have a r epresentative from each region. Currently the 

following have regions have provided a representative; NEWMA, Frank Greene, (Connecticut) and WWMA, 

Mr. Brett Gurney (Utah). T he following individuals have also expressed interest: Ms. Maile Hermida (Hogan 

Lovells US, LLP), Ms. Ann Boeckman (Kraft Foods Group), Mr. Pete O’Bryan (Foster Farms), Mr. Chris Guay 

(Procter and Gamble Co.). Mr. Floren remarked that meetings will be held via web-meetings and at the NCWM 

Conferences.

270-4 D Handbook 130, Engine Fuels and Automotive Lubricants, Section 4.3. Dispenser 

Filters

This appeared as Informational Item 237-8 in the Committee Reports for the 98th Annual Meeting (NCWM 

Publication 16, 2013). 

Source: 

Missouri Department of Agriculture (2012)

Purpose: 

Recognize the need for 10-micron or smaller nominal pore-sized filters for today’s diesel engines.

Item Under Consideration:

4.3. Dispenser Filters.

4.3.1. Engine Fuel Dispensers.

(a) All gasoline, gasoline-alcohol blends, gasoline-ether blends, biodiesel, biodiesel blends, diesel,

E85 fuel ethanol, and M85 methanol dispensers shall have a 10 micron or smaller nominal poresized filter.

(b) All biodiesel, biodiesel blends, diesel, and kerosene dispensers shall have a 30 micron or smaller 

nominal pore-sized filter.

Background/Discussion: 

Abnormal dispenser filter plugging at retail will alert the retailer of potential storage tank problems. Requiring 

10-micron filters for all products will reduce the inventory and the potential of installing the wrong filter for all 

products at the same site.

2011 CWMA Interim Meeting: An official commented that a smaller porosity filter may be acceptable but for now 

this is a reasonable start. CWMA forwarded the item to NCWM recommending it as a Voting Item. 

2011 WWMA Annual Meeting: Need was expressed for more technical information and there were concerns that 

the flow rate would be diminished, the size of the filter may need to increase, and coupled with biodiesel it would 

tend to clog the filter in colder climates. Because of these reasons the Committee did not believe there was 

sufficient data to justify addressing this issue. WWMA did not forward the item to NCWM and recommended that 

the submitter provide additional studies and technical documents to support this proposal. 

2011 NEWMA Interim Meeting: Questions were raised as to whether or not “measurement” of filter content was 

within the ability of weights and measures officials. It was noted that better filters may enhance fuel quality. The 

Committee believes that the proposal has potential, given input from industry and NCWM members. N EWMA 

forwarded the item to NCWM recommending it as a Developing Item. 

2011 SWMA Annual Meeting: An industry representative stated that standard retailer dispensers use a 10-micron 

filter, and high capacity dispensers use 30-micron filters (i.e., diesel dispensed at truck stops). The company’s 

engineers have determined that reducing a 30-micron filter to a 10-micron filter will drastically reduce flow rate to 

trucks. Another industry representative agreed and re-iterated that truck stops would see a tremendous reduction in 

flow. The Committee believed this proposal was not practical and would have a negative impact and undue burden 

on the trucking industry. SWMA did not forward the item to NCWM. 
L&R Committee 2013 Final Report

L&R - 77

2012 NCWM Interim Meeting: Mr. Ron Hayes, FALS Chair, informed the Committee that FALS recommended 

that this item be Informational because of industry concerns that 10-micron filters would be too restrictive of flow in 

high-flow systems. One industry representative expressed opposition for the use of 10-micron filters and 

recommends this item to be Withdrawn. A representative of an automobile manufacturer claimed diesel passenger 

vehicles do not have the sophisticated filtration systems commonly found on commercial duty vehicles and 

10-micron filters on dispensers are needed for protection from particulate contamination. As proposed, this item 

could cause clogging of diesel dispenser filters in colder climates. The Committee believes this item has merit but 

lacks a consensus and also believes that FALS needs to address these concerns. The 2012 L&R Committee

designated this item as an Informational Item and assigned it to FALS for further development.

2012 NCWM Interim Meeting: It was apparent to the Committee that that there are many unresolved issues related 

to passenger vehicles. The Committee encourages the FALS to continue developing this item. 

2012 NEWMA and CWMA Annual Meetings: Both Associations supported this item and recommended that the 

item be a Voting Item.

2012 NCWM Annual Meeting: Several stakeholders spoke in opposition on this item. Mr. Hayes remarked that the 

FALS worked on this item in 2007 and believes FALS needs to continue to work on this item. The NCWM L&R 

Committee agreed that this item is not ready and supports the continued development by FALS.

2012 CWMA Interim Meeting: General Motors (GM) supported this item for passenger vehicles, as these vehicles 

now have 4-micron filters. A state official commented that the CWMA had recommended modifying the language 

in this item to state that the 10-micron filter requirement would only apply to passenger type vehicles, and would 

specifically exempt high flow rate meters such as truck stop meters. CWMA supported this item provided that the 

earlier proposal be presented to limit the 10-micron filters to passenger vehicle meters and to specifically exempt 

high flow rate meters. CWMA recommended that this version of the item be a Voting Item. 

2012 WWMA Annual Meeting: Mr. Gordon Johnson (Gilbarco) opposed the item because reducing a 30-micron 

filter to a 10-micron filter would drastically reduce flow rate to large capacity over-the-road trucks. The Committee 

did not believe that this issue falls within the scope of weights and measures and, therefore, would be unenforceable. 

No comments were received to support the item. WWMA recommended that this item be Withdrawn.

2012 SWMA Annual Meeting: An industry representative commented that the current technology to put a 

10-micron filter on diesel at a truck stop will prohibit fuel from being dispensed in a timely manner and, therefore, 

opposes this. The Committee recommended that use of 10-micron filters be limited to passenger vehicle meters, and 

to specifically exempt high flow rate meters. SWMA recommended that the item be a Voting Item but with the 

changes as described by the Committee.

2012 NEWMA Interim Meeting: NEWMA reviewed comments from the CWMA meeting. NEWMA recommends 

review by the Fuels and Lubricants Subcommittee. NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: Mr. Hayes (FALS Chair) remarked that a s imilar item was brought before the 

Committee in 2007. FALS did not have enough time in their work session to work on this item. There are several 

stakeholders and states that are having issues with the terminology and would like it removed from the agenda. 

Mr. Hayes (Missouri) remarked that they supported this item because contamination is an issue with cars that do not 

have filtering systems. The Committee reviewed comments from the Regional Associations; however; FALS did 

not have sufficient time review and consider recommendation to the Committee. The Committee would like for 

FALS to continue to work on this item and is proposing this as an Informational Item. 

2013 CWMA Annual Meeting: Several industry representatives did not support this item for they believe this was 

more of a dispenser protection issue than a consumer protection issue. A state regulator remarked it is a fuel quality 

issue to protect the consumer’s vehicles and fuels systems such as high pressure fuel rails on newer diesel vehicles. 

This would not apply to high-flow diesel dispensers

2013 NEWMA Annual Meeting: The Committee proposes this item be Withdrawn.
L&R Committee 2013 Final Report

L&R - 78

2013 NCWM Annual Meeting: Mr. Hayes (FALS Chair) requested that the Committee allow the Subcommittee to 

continue to work on a recommendation for this item. There was opposition on moving this item forward. In less 

than two years since this proposal came forward, there has been no data developed. The Committee reviewed the 

association reports, Open Hearing comments, and letters received and changed the status of this item to Developing.

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to 

Appendix F in the Report of the 97th National Conference on Weights and Measures (SP 1160, 2012) and

documents. 

270-5 D Handbook130, Section 4.3. Paper Plates and Sanitary Paper Products

Source: 

Georgia Pacific (2013)

Purpose: 

Add a more accurate and reproducible test method for verifying dimensions of disposable plates, bowls, and platters. 

Item Under Consideration: 

Amend NIST Handbook 133 as follows:

This appeared as Voting Item 260-4 in the Committee Reports for the 98th Annual Meeting (NCWM 

Publication 16, 2013). 

4.3. Paper Plates and Sanitary Paper Products

The following procedure is used to verify the size of paper plates and other sanitary paper products. It may also be 

used to verify the size declarations of other disposable dinnerware.

Note: Do not distort the item’s shape during measurement.

The count of sanitary paper products cannot be adequately determined by weighing. Variability in sheet weight and 

core weight requires that official tests be conducted by actual count. However, weighing can be a useful audit 

method. T hese products often declare total area as well as unit count and sheet size. I f the actual sheet size 

measurements and the actual count comply with the average requirements, the total area declaration is assumed 

correct.

4.3.1. Test Equipment

• Steel tapes and rules. Determine measurements of length to the nearest division of the appropriate tape 

or rule.

 Metric Units:

For labeled dimensions 40 cm or less, linear measure: 30 cm in length, 1 mm divisions; or a 1 m 

rule with 0.1 mm divisions, overall length tolerance of 0.4 mm.

For labeled dimensions greater than 40 cm, 30 m tape with 1 mm divisions.

 Inch-pound Units:

For labeled dimensions 25 in or less, use a 36 in rule with 1

/64 in or 1/100 in divisions and an overall 

length tolerance of 1

/64 in.
L&R Committee 2013 Final Report

L&R - 79

For dimensions greater than 25 in, use a 100 ft tape with in divisions and an overall length 

tolerance of 0.1 in.

• Measuring Base. 

Note: A measuring base may be made of any flat, sturdy material approximately 38 cm (15 in) square. Two 

vertical side pieces approximately 3 cm (1 in) high and the same length as the sides of the measuring base are 

attached along two adjoining edges of the measuring base to form a 90° corner. Trim all white borders from 

two or more sheets of graph paper (10 divisions per centimeter or 20 divisions per inch). Place one sheet on the 

measuring base and position it so that one corner of graph paper is snug in the corner of the measuring base and 

vertical sides. Tape the sheet to the measuring base. Overlap other sheets on the first sheet so that the lines of 

top and bottom sheet coincide, expanding the graph area to a size bigger than plates to be measured; tape these 

sheets to the measuring base. Number each line from the top and left side of base plates: 1, 2, 3, etc.

• Plate Dimension Tester

4.3.2. Test Procedure 

1.* Follow Section 2.3.1. “Define the Inspection Lot.” U se a “ Category A” sampling plan in the 

inspection; select a random sample.

2. Select an initial tare sample according to Section 2.3.5.1. “Determination of Tare Sample and 

Average Tare Weight.”

3. Open each package and select one item from each.

Note: Some packages of plates contain a combination of different-sized plates. In this instance, take a plate of 

each declared size from the package to represent all the plates of that size in the package. For example, if three 

sizes are declared, select three different plates from each package.

Note: Occasionally, packages of plates declared to be one size contain plates that can be seen by inspection to 

be of different sizes in the same package. In this instance, select the smallest plate and use the methods below 

to determine the package error. If the smallest plate is not short measure by more than the MAV, measure each 

size of plate in the package and calculate the average dimensions.

Example: 

If five plates measure 21.41 cm (8.43 in) and 15 measure 21.74 cm (8.56 in), the average dimension 

for this package of 20 plates is 21.66 cm (8.53 in).

4. For paper plates bowls or platters: Place each item on the plate dimension tester or measuring base 

plate (or use the linear measure) with the eating surface down so two sides of the plate touch the sides 

of the plate dimension tester or measuring base. If using the plate dimension tester, follow the test 

procedure for determining the plate, bowl or platter size.
L&R Committee 2013 Final Report

L&R - 80

5. For other products: Use either the measuring base or a linear measure to determine actual labeled 

dimensions (e.g., packages of napkins, rolls of paper towels). If testing folded products, be sure that 

the folds are pressed flat so that the measurement is accurate.

6. If the measurements reveal that the dimensions of the individual items vary, select at least 10 items 

from each package. Measure and average these dimensions. Use the average dimensions to 

determine package error in Step 7 below.

7. The package error equals the actual dimensions minus the labeled dimensions.

4.3.3. Evaluation of Results

Follow the procedures in Section 2.3.7. “Evaluate for Compliance” to determine lot conformance.

Background/Discussion: 

NIST Handbook 133, Section 4.3. Paper Plates and Sanitary Paper Products, identifies “Metric” and/or “InchPound” steel tapes and rules or a “measuring base” as acceptable equipment for doing dimensional evaluations of 

paper plates and sanitary paper products. This proposal would add another acceptable piece of equipment that we 

call the ‘Plate Dimension Tester.” 

It is simpler, faster, and easier for an operator, technician, or regulator to use, and it is or more accurate and 

reproducible than the existing acceptable equipment listed in NIST Handbook 133, Section 4.3. Paper Plates and 

Sanitary Paper Products. For most products of this type (11.8 in or less) the current metric rule is identified as a 

30 mm rule in 1 mm divisions (0.039 in), or a 1 m rule with 0.1 mm divisions (0.0039 in), and the inch-pound rule is 

a 36 inch rule with 1/64 or 1/100 divisions (0.015 in or 0.01 in). The acceptable divisions are somewhat different. The 

proposed tester uses a certified steel rule with divisions of 0.02 in that falls within the range of acceptable rules 

already listed in Section 4.3. Paper Plates and Sanitary Paper Products.

The measuring base described as acceptable uses graph paper with divisions of 0.05 in. That measuring base is 

described and constructed as follows:

A measuring base may be made of any flat, sturdy material approximately 38 cm (15 in) square. Two vertical 

side pieces approximately 3 cm (1 in) high and the same length as the sides of the measuring base are attached 

along two adjoining edges of the measuring base to form a 90 degree corner. Trim all white borders from two 

or more sheets of graph paper (10 divisions per centimeter or 20 divisions per in). Place one sheet on the 

measuring base and position it so that one corner of graph paper is snug in the corner of the measuring base 

and vertical sides. Tape the sheet to the measuring base. Overlap other sheets on the first sheet so that the 

lines of top and bottom sheet coincide, expanding the graph area to a size bigger than plates to be measured; 

tape these sheets to the measuring base. N umber each line from the top and left side of base 

plates: 1, 2, 3, etc.

The submitter believes the accuracy of cutting the borders off the edges of graph paper, aligning the graph paper 

lines to match, and then taping them in place leaves a lot to be desired for accuracy when gathering data; especially 

when the expectations require the values to be read to such small increments. The plates need to touch the two sides 

of the measuring base, which require holding the plate flat against the measuring base and changes in that pressure 

can alter the values. The process of using rules can also cause problems when the plate edge must be perfectly 

aligned with the edges of the rule and then to make sure you have measured both directions in a perfect 90 degree

angle. We, therefore, developed the Plate Dimension Tester to solve all those problems. He submitted separately 

pictures of the tester, a test procedure for using the tester, a video showing the use of the tester, some reproducibility 

data, and a letter from the Foodservice Packaging Industry (FPI), which represents 85 % of the companies producing 

these types of products, indicating their industry Technical Committee supports this proposal. The submitter 

believes his method would be a positive addition to NIST Handbook 133 without changing any of regulatory 

requirements; simply improving on the technical accuracy and reproducibility of the resulting data generated.
L&R Committee 2013 Final Report

L&R - 81

The Standard Test Method is contained in Appendix F (Report of the 98th National Conference on Weights and 

Measures [2013]) as well as additional pictures, reproducibility data, and a blueprint of a Plate Dimension Tester. 

2012 SWMA Annual Meeting: Mr. Richard Davis (Georgia Pacific) expressed concern that importers are not 

compliant and are causing unfair competition to U.S. manufacturers (e.g., a 1

/8 inch shortage in a paper plate can 

equate to over $100,000 unfair advantage). Mr. Davis has submitted this proposal that would add an additional test 

method but would not change the current test procedures (steel rule or graph paper) in NIST Handbook 133. 

Mr. Davis believes that this is a more accurate procedure than what is currently adopted and would provide support 

if challenged in court. The device has an estimated cost of $3000 and would be available through a third party. A 

video was shown describing how to operate and test. An industry official expressed concern on whether the 

equipment and disc can be certified and calibrated by a state lab. The Committee believes that the device would 

provide an additional option and improved test procedures for regulators and industry. SWMA forwarded the item 

to NCWM, recommending it as a Voting Item.

2013 NEWMA Annual Meeting: The Association heard from the Ms. Hockert that the NIST Dimensional 

Laboratory reported no problems with the testing device. Based on this new information, NEWMA believes this 

item is fully developed and recommends this as a Voting Item.

2013 CWMA Annual Meeting: The Association agreed that this is an improved test method and recommends it as a 

Voting Item.

2013 NCWM Interim Meeting: Mr. Davis provided a presentation that showed an overview on the test standard and 

equipment they are proposing to use in the test procedure. Mr. Davis believes that the item presented before the 

Committee will allow for greater efficiency, accuracy, repeatability, and uncertainty. This device will also allow for 

the testing of other products such as paper towels, napkins, and sandwich bags. Ms. Carol Hockert (NIST, OWM) 

volunteered to take the information to the NIST Dimensional Laboratory for further accuracy testing. The 

Committee feels that this item is developed and is recommending this item as a Voting Item. 

2013 NCWM Annual Meeting: The Committee believes that additional work is needed on this item. The procedure 

title may need to reflect bowls and platters. A separate NIST Handbook 133 procedure also needs to be created in 

order to utilize the Plate Dimension Tester. Some spoke that it is not feasible to place the Plate Dimension Tester in 

the current test procedure in NIST Handbook 133 (2013). The Item Under Consideration also has a TAPPI standard 

reference, and there was not a copy of this standards available for review. There was testimony heard on this item, 

and it was concluded that it needs further development. The Committee returned this item to Developing status to 

give the submitter an opportunity to further develop this item. 

Additional letters, presentations, and data may have been part of the Committee’s consideration. Please refer to 

Appendix C, Report of the 97th National Conference on Weights and Measures (SP 1160, 2012) and Appendix F of 

this report (Report of the 98th National Conference on Weights and Measures [2013]) to review these documents.

270-6 D Section 3.10. Animal Bedding 

This appeared as Voting Item 260-2 in the Committee Reports for the 98th Annual Meeting (NCWM 

Publication 16, 2013). A the 2013 NCWM Annual Meeting the Committee Modified the status of this item to 

a Developing Item. This is now identified as Item 270-6.

Source: 

Central Weights and Measures Association (2012)

Purpose: 

This proposal is to clarify appropriate test procedures for animal bedding.

Item Under Consideration: 

Amend NIST Handbook 133, Test Procedures – For Packages Labeled by Volume as follows:
L&R Committee 2013 Final Report

L&R - 82

3.10. Mulch, and Soils, and Animal Bedding Labeled by Volume

Mulch is defined as “any product or material except peat or peat moss that is advertised, offered for sale, or sold for 

primary use as a h orticultural, above-ground dressing, for decoration, moisture control, weed control, erosion 

control, temperature control, or other similar purposes.”

Soil is defined as “any product or material, except peat or peat moss that is advertised or offered for sale, or sold for 

primary use as a horticultural growing media, soil amendment, and/or soil replacement.”

Animal bedding is defined as “any product or material, except for baled straw or peat moss, that is 

advertised, offered for sale, or sold for primary use as a medium for animals to bed, nest or eliminate waste, 

such as compressed wood pulp or cellulose fibers (confetti, granules, or pellets), softwood shavings, shredded 

paper, compressed coconut fiber, ground corn cob, pelleted paper or wheat straw, cotton fibers, and bamboo 

products or any other material.”

Animal bedding as “animal bedding of all kinds, except for baled straw”

3.10.1. Test Equipment:

• A test measure appropriate for the package size that meets the specifications for test measures in 

Table 3-4. “Specifications for Test Measures for Mulch, and Soils and Animal Bedding” 

• Drop cloth/polyethylene sheeting for catching overflow of material

• Level (at least 15 cm [6 in] in length)

Measures are typically constructed of 1.27 cm (1⁄2in) marine plywood. A transparent sidewall is useful for 

determining the level of fill, but must be reinforced if it is not thick enough to resist distortion. If the measure has a 

clear front, place the level gage at the back (inside) of the measure so that the markings are read over the top of the 

mulch. 

Notes

1 Other interior dimensions are acceptable if the test measure approximates the configuration of the package under 

test and does not exceed a base configuration of the package cross-section. 

2

The height of the test measure may be reduced, but this will limit the volume of the package that can be tested.

3

When lines are marked in boxes, they should extend to all four sides of the measure if possible to improve 

readability. It is recommended that a line indicating the MAV level also be marked to reduce the possibility of 

reading errors when the level of the mulch is at or near the MAV.

4

The Nominal Capacity is given to identify the size of packages that can be tested in a single measurement using the 

dry measure with the listed dimensions. It is based on the most common package sizes of mulch in the marketplace. 

If the measures are built to the dimensions shown above the actual volume will be larger than the nominal volume so 

that plus errors (overfill) can be measured accurately.

3.10.2. Test Procedure 

1. Follow the Section 2.3.1. “Define the Inspection Lot.” Use a “C ategory A” sampling plan in the 

inspection, and select a random sample.

2. Open each package in turn. E mpty the contents of the package into a t est measure and level the 

contents by hand. Do not rock, shake, drop, rotate, or tamp the test measure. Read the horizontal 

marks to determine package net volume.

Note: Mulch: Some types of mulch are susceptible to clumping and compacting. Take steps to ensure 

that the material is loose and free flowing when placed into the test measure. Gently roll the bag before 

opening to reduce the clumping and compaction of material.

Compressed state animal bedding: To measure the usable volume, first empty the contents of the 

package on a drop cloth. Using your hands, or a tool if necessary, loosen the material until it is free 

of all clumps and compaction. When the product is free flowing, place in a test measure. To 

determine volume of the compressed state animal bedding, follow Section 3.9.1. “Compressed 

Volume Packages.”

3. Exercise care in leveling the surface of the mulch/soil/animal bedding and determine the volume 

reading from a position that minimizes errors caused by parallax.

4. Determine package errors by subtracting the labeled volume from the package net volume in the 

measure. Record each package error.

Package Error = Package Net Volume − Labeled Volume

3.10.3. Evaluation of Results

Follow the procedures in Section 2.3.7. “Evaluate for Compliance” to determine lot conformance.

Note: In accordance with Appendix A, Table 2-10. Exceptions to the Maximum Allowable Variations for 

Textiles, Polyethylene Sheeting and Film, Mulch and Soil Labeled by Volume, Packaged Firewood, and 

Packages Labeled by Count with 50 Items or Fewer, and Specific Agricultural Seeds Labeled by Count, apply 

an MAV of 5 % of the declared quantity to mulch, and soil and animal bedding sold by volume. When testing 

mulch and soil with a net quantity in terms of volume, one package out of every 12 in the sample may exceed 

the 5 % MAV (e.g., one in a sample of 12 packages; two in a s ample of 24 packages; four in a s ample of 

48 packages). However, the sample must meet the average requirement of the “Category A” Sampling Plan.
L&R Committee 2013 Final Report

L&R - 85

Table 2-10. Exceptions to the Maximum Allowable Variations for Textiles, Polyethylene Sheeting and 

Film, Mulch, and Soils, and Animal Bedding Labeled by Volume, Packaged Firewood, and Packages 

Labeled by Count with 50 Items or Fewer, and Specific Agricultural Seeds Labeled by Count. 

Maximum Allowable Variations (MAVs)

Mulch, And Soil, and 

Animal Bedding Labeled By 

Volume

The MAVs are:

For individual packages: 5 % of the labeled volume.

For example: One package may exceed the MAV for every 12 packages 

in the sample (e.g., when the sample size is 12 or fewer, 1 package may 

exceed the MAV and when the sample size is 48 packages, 4 packages 

may exceed the MAV).

NOTE: For Animal Bedding there is a temporary exemption not to 

apply the MAV. After July 2017, there will be an MAV of 5 % of the 

labeled volume applied to “animal bedding”

(Amended 2010 and 20XX) 

Background/Discussion: 

NIST Handbook 130, Uniform Regulation for the Method of Sale, Section 2.23. Animal Bedding states:

2.23. Animal Bedding. – Packaged animal bedding of all kinds, except for baled straw, shall be sold by 

volume, that is, by the cubic meter, liter, or milliliter and by the cubic yard, cubic foot, or cubic inch. If the 

commodity is packaged in a compressed state, the quantity declaration shall include both the quantity in the 

compressed state and the usable quantity that can be recovered.

Example: 250 mL expands to 500 mL (500 in3 expands to 1000 in3

).

(Added 1990) (Amended 2012)

However, NIST Handbook 133 does not include specific procedures for testing animal bedding volume declarations, 

compressed state quantity declarations, or usable quantity declarations. This proposal is to clarify appropriate test 

procedures for animal bedding. 

2011 CWMA Interim Meeting: CWMA received this proposal and forwarded the item to NCWM recommending it 

as a Voting Item. 

2012 NCWM Interim Meeting: The Committee made minor editorial changes to align the proposal with the format 

and language currently in NIST Handbook 133. The submitter had the word “uncompressed” added under the note 

section within “Evaluation of Results.” The Committee agreed and recommended to remove this word.

This proposal includes adopting both the mulch and soil test method and the evaluation of results for animal 

bedding. T he method of evaluating results for mulch and soil testing includes an exception to the maximum 

allowable variation (MAV), the MAV is 5 %, and one package out of a 12 item sample (2 packages in a 24 item 

sample, 4 packages in a 48 item sample) is allowed to exceed the MAV. H owever, the sample must meet the 

average requirement of “Category A.” This MAV exception for mulch and soil was developed based on a study of 

mulch and soil test results. The Committee will ask industry to submit animal bedding product information and test 

data to determine if the MAV exception is appropriate for animal bedding.

An animal bedding industry representative was supportive of the 5 % allowance and also recommended a

12 × 12 × 12 cu ft vessel. The submitter of the proposal has been using the mulch test procedure to test animal 
L&R Committee 2013 Final Report

bedding and has not had issues using the procedure under the item for consideration. The 2012 L&R Committee

designated this item as an Informational Item.

2012 NEWMA Annual Meeting: There were no comments. NEWMA recommended that the item remain as an 

Informational Item.

2012 CWMA Annual Meeting: Ms. Judy Cardin (Wisconsin) reported that there is no standard for animal bedding. 

Subsequently industry is using a variety of test methods that produce varying results. Wisconsin tested and found a 

wide variance in net quantity accuracy and found significant shortages in several instances. She encouraged other 

jurisdictions to test animal bedding and to share data with NIST, OWM. Missouri did a lot of testing at one facility 

and found a maximum of 36 % shortage and an average of 23 % shortage. Missouri’s analysis further showed that 

the chipper had a g reat impact of the “spring effect” of compression. An industry representative recommended 

developing a method of sale for this commodity when sold from bulk since a significant amount of horse bedding is 

purchased in bulk. CWMA recommended that the item remain as an Informational Item.

2012 NCWM Annual Meeting: The L&R Committee requested that regulators and industry conduct animal bedding 

package testing, and submit their test results to Ms. Cardin at judy.cardin@wi.gov or to Mr. David Sefcik (NIST, 

OWM) at dsefcik@nist.gov. Preliminary analysis by NIST of available test data indicates that an exception for 

MAV is necessary for this product, but the Committee needs additional test data to determine the appropriate 

amount for that exception. 

2012 CWMA Interim Meeting: There is no package testing standard in NIST Handbook 133 for animal bedding, 

and industry is currently using a variety of test methods that are resulting in significant non-compliance on package 

weights. Ms. Cardin announced that she is coordinating an animal bedding package testing survey to provide data to 

determine the appropriate exception to MAV for animal bedding. She asked CWMA states to participate in the 

October to November 2012 testing. A few states agreed to participate. CWMA recognized many states may not be 

able to participate given limited resources. The CWMA supported this item and recommended that the item be a 

Voting Item based on an appropriate MAV as determined by the study or, if the data is insufficient, using the 

established MAV for mulch, a similar product.

2012 WWMA Annual Meeting: M r. Kurt Floren (Los Angeles County, California) remarked that this item is 

noteworthy but questioned whether it recognizes all types of animal bedding in the marketplace (e.g., ground corn 

cobs and shredded paper). Ms. Macey commented in support, but she would like to see additional data collected. 

The NIST Technical Advisor requested that states submit data on animal bedding inspections to NIST. T he 

Committee agreed that more studies and data are needed and recommended that the results be submitted to the 

NCWM. The Committee believed that a better definition is needed to address various animal bedding products. 

WWMA recommended that the item be an Informational Item.

2012 SWMA Annual Meeting: A NIST Technical Advisor commented that the chair of the NCWM L&R is 

requesting states to participate in the package testing of animal bedding over the next two months in order to provide 

more data to help determine the appropriate MAV. SWMA recommended that the item be an Informational Item 

unless there is strong evidence from the survey for an appropriate MAV; in which case, SWMA would recommend 

it as a Voting Item.

2012 NEWMA Annual Meeting: NEWMA would like to see results of the CWMA study before action is taken on 

the proposal. NEWMA recommended that the item be an Informational Item.

2013 NCWM Interim Meeting: Mr. David Sefcik provided a summary of the data that was received from states and 

manufacturers that tested animal bedding. The findings were limited participation and very few lots passed; 

therefore, NIST could not make a r ecommendation for a M AV. D ata shows there is a b igger concern than 

determining correct MAV. Even with applying a 5 % MAV, almost all the lots would have failed. There were also 

significant variations in labeled content, variability on bedding materials, different types of packing machines, and 

volumetric test measures. It was agreed the test procedure for mulch could be used for animal bedding. T he 

recommendation made was the Committee should consider a temporary exemption from the MAV (three to five 

years). T his would provide an exemption from the current MAV which is too restrictive while giving the 
L&R Committee 2013 Final Report

L&R - 87

Committee and NIST additional time for data to be collected to determine the proper MAV. NIST will work with 

stakeholders to develop a standardized test measure.

Mr. Jim Byers (San Diego County, California) expressed concern that animal bedding needs to be clearly defined. 

Mr. Byers submitted recommended language to define animal bedding as follows:

Section 3.10. Mulch, and Soils, and Animal Bedding Labeled by Volume

“Any product or material, except for baled straw, that is advertised, offered for sale, or sold for primary 

use as a medium for animals to bed, nest or eliminate waste, such as compressed wood pulp or cellulose 

fibers (confetti, granules, or pellets), softwood shavings, shredded paper, compressed coconut fiber, 

ground corn cob, pelleted paper or wheat straw, cotton fibers, and bamboo products or any other 

material.”

Mr. Floren agrees with Mr. Byers and Mr. Sefcik on their recommendations. Mr. Rich Whiting (American Wood 

Fibers) spoke that they participated and their lots did not pass. American Wood Fibers would like to see a test 

measure and quantity control practices developed by NCWM. 

The Committee agrees with the definition for animal bedding drafted by Mr. Byers with the addition of peat moss as 

an exemption. I t was agreed to remove the MAV requirement for animal bedding, and the Committee is 

recommending that the states test animal bedding on the “average requirement.” T he removal of the MAV for 

animal bedding would be a temporary exemption for a four-year period; after which time, the MAV would default to 

the 5 %. There was no objection from NIST on the test procedure. Information will need to be obtained from 

industry to determine an accurate test measure. I t was also agreed to put a sunset date of July 2017 into the 

language. With these changes, the Committee proposes this as a Voting item.

2013 NEWMA Annual Meeting: The NIST Technical Advisor remarked that they continue to collect data on this 

subject matter. The Committee believes that there is sufficient data to support this item and recommends it as a 

Voting Item.

2013 CWMA Annual Meeting: The NIST Technical Advisor remarked that the date in the MAV table was open 

ended and consideration should be given to make it date specific. NIST continues to analyze testing data. States 

should continue to send test data to NIST. The Committee recommends that a date for the temporary exemption 

read July 1, 2017, and moves this forward as a Voting Item. 

2013 NCWM Annual Meeting: A regulator opposed the item as written due to animal bedding being defined within 

a test procedure for mulch and soil. He questions how the 5 % MAV was calculated. He also does not recommend 

a fix of applying a temporary MAV exemption. The Committee concurs that this item is not ready to move forward 

as a Voting Item and moved this item to Developing so the submitter can further develop. The definition needs to 

be reviewed to determine any exemptions that may apply for items currently sold by weight. R econsideration 

should also be given to whether a three-year exemption to the MAV is appropriate. The Committee believes this 

item needs to be further developed and returned to the submitter.

API supports the current language in Handbook 130 paragraphs 2.33.1.4.1 and 3.13.1.4.1 approved at 

the July 2012 National Conference on Weights and Measures meeting. In response to the comments 

received in support of new items 232-2 and 237-4, we offer the following comments for consideration.

• “Older, specialty, and some non-American vehicles take engine oil not listed as active under API’s 

private regulatory scheme”

– API’s Engine Oil Licensing and Certification System is a voluntary program based on 

consensus-based industry standards; it’s not a private regulatory scheme.

– API and ILSAC standards are developed in cooperation with OEMs, oil marketers, 

additive companies, test labs, and other interested parties. This includes AOCA.

– API declares categories obsolete when the tests used to verify those levels of

performance no longer exist. 

• For example, API SG was in use through 1993, but the engine tests used to 

measure SG performance are no longer available. The engine manufacturers 

stopped making the engines and parts used by the tests.

• Without SG engine tests, oil marketers might be able to refer to old SG data to 

confirm an SG oil’s ability to protect against wear and prevent sludge and 

varnish. Marketers seeking to develop new SG formulations don’t have SG 

engine tests to verify performance.

• “If OEMs recommend those engine oils for their vehicles, consumers have a right to use them 

regardless of API’s blessing, and installers and retailers should be able to sell them without 

obstruction”

– API doesn’t recommend engine oils for vehicles—OEMs do.

– Most US, Japanese and South Korean OEMs recommend oils licensed to use the API 

Starburst. 

• The Starburst identifies oils meeting the most recent ILSAC performance 

standard. Today, that’s GF-5. If the Starburst appears in an owner’s manual, the 

OEM is recommending the vehicle owner use GF-5.

• The Starburst system is possible because oils meeting ILSAC standards are 

backward compatible: the latest ILSAC standard meets or exceeds the previous 

standard. If an owner’s manual for a 1998 model year vehicle includes the 

Starburst, the OEM is recommending the owner use the latest ILSAC standard 

(in this case GF-5).

– If an installer stocks in bulk an oil meeting an older API performance standard (for 

example API SF), how would the installer ensure this older oil is not installed in a newer 

engine unless the installer follows the requirements in the approved National 

Conference language?

• “The average fast lube customer doesn’t recognize API or SAE to mean anything in particular”

– We agree—that’s why API launched a new program to educate marketers, distributors, 

installers and consumers on the importance of oil quality.

– This includes educating everyone on the meaning of the API Starburst and Donut. 

• “When API publishes a new edition of 1509 and/or creates a new service category, a reasonable 

phase-in period for bulk oil stock is necessary to accommodate older vehicle owners’ needs”

– API provides a phase-in for all new API Starburst and Donut performance standards. 

• We start with a six- to nine-month waiting period before API begins licensing

oils against the standard.

• This is followed by a one-year period when the previous and new standards coexist. 

• Then, according to OEM recommendations, consumers with a Starburst in their 

owner’s manual are recommended to start using oil’s meeting the new 

standard. 

– API does maintain older standards where possible. Currently, three older “S” categories 

(SJ, SL, and SM) can still be licensed. This is possible because the engine tests for these 

categories are still available.

• “Although it is common for API to retain a couple of the most recent service categories as 

“active,” API could choose to make all but the most recent service category “obsolete’”

– API declares service categories obsolete when the tests used to verify their performance 

are no longer available.

– If API were to consider making a category obsolete while the engine tests were still 

available, API would need to ballot the change through our consensus-based standardssetting process. 

• “And what about packaged engine oil products already on the shelf or in the distribution chain 

when API makes a unilateral decision to deactivate an engine oil category?”

– API-licensed products packaged before category obsolescence are considered licensed 

after the obsolescence date. We can verify date of manufacture through the oil bottle’s 

traceability code. All packaged API-licensed oils are required to include traceability 

codes.

– Unilateral decision? No tests available results in category obsolescence.

Draft NIST Handbook 130 Method of Sale for Electricity as Vehicle Fuel

B. Uniform Regulation for the Method of Sale of Commodities

as adopted by

The National Conference on Weights and Measures*

1. Background 

The National Conference on Weights and Measures (NCWM) has long been concerned with the proper units of 

measurement to be used in the sale of all commodities. This approach has gradually broadened to concerns of 

standardized package sizes and general identity of particular commodities. Requirements for individual products 

were at one time made a part of the Weights and Measures Law or were embodied in separate individual Model 

Regulations. In 1971, this “Model State Method of Sale of Commodities Regulation” was established (renamed in 

1983); amendments have been adopted by the Conference almost annually since that time.

Sections with “added 1971” dates refer to those sections that were originally incorporated in the Weights and 

Measures Law or in individual Model Regulations recommended by the NCWM. Subsequent dates reflect the 

actual amendment or addition dates.

The 1979 edition included for the first time requirements for items packaged in quantities of the International 

System of Units (SI), the modernized metric system, as well as continuing to present requirements for inch-pound 

quantities. It should be stressed that nothing in this Regulation requires changing to the SI system of measurement. 

SI values are given for the guidance of those wishing to adopt new SI quantities of the commodities governed by 

this Regulation. SI means the International System of Units as established in 1960 by the General Conference on 

Weights and Measures and interpreted or modified for the United States by the Secretary of Commerce.

This Regulation assimilates all of the actions periodically taken by the Conference with respect to certain food 

items, non-food items, and general method of sale concepts. Its format is such that it will permit the addition of 

individual items at the end of appropriate sections as the need arises. Its adoption as a regulation by individual 

jurisdictions will eliminate the necessity for legislative consideration of changes in the method of sale of particular 

commodities. Such items will be able to be handled through the normal regulation-making process.

2. Status of Promulgation 

The table beginning on page 10 shows the status of adoption of the Uniform Regulation for the Method of Sale of 

Commodities.

*The National Conference on Weights and Measures (NCWM) is supported by the National Institute of Standards 

and Technology (NIST) in partial implementation of its statutory responsibility for “cooperation with the states in 

securing uniformity in weights and measures laws and methods of inspection.”

NIST Status Report

[1/23/13]

Group: NIST U.S. National Work Group on Measuring Systems for Electric Vehicle Fueling and Submetering 

(USNWG EVF&S)

Scope and Purpose: In August 2012, NIST formed the USNWG EVF&S to develop proposed requirements for 

commercial electricity-measuring devices (including those used in sub-metering electricity at residential and 

business locations and those used to measure and sell electricity dispensed as a vehicle fuel) and to ensure that 

the prescribed methodologies and standards facilitate measurements that are traceable to the International 

System of Units (SI). This work is not intended to address utility metering in the home or business where the 

metered electricity is consumed by the end purchaser and that falls under the authority of entities such as the 

local utility commission.

Meetings: On August 29, 2012, the USNWG held its first meeting via web conference. During this meeting, 

USNWG administrative issues and structure were covered.

In November 2012, NIST OWM prepared and distributed draft proposals for method of sale requirements (for 

inclusion in NIST HB 130) and a device code (for inclusion in NIST HB 44) to USNWG members. 

Based on comments received, NIST OWM prepared updated drafts of these proposals and distributed them at a 

second USNWG meeting held January 15-17, 2013 at NIST in Gaithersburg, MD. Of the 35 total attendees, 18 

USNWG members and 6 NIST OWM staff members attended in person, while 11 USNWG members attended 

online. Attendees included representatives from:

o vehicle charging equipment and electric meter manufacturers,

o State and local weights and measures jurisdictions,

o energy distribution companies and service providers,

o national laboratories,

o technical committees (e.g., the ANSI C12 Chair),

o standards organizations (i.e., UL and NEMA), 

o NIST OWM and NIST Smart Grid Interoperability Panel.

After reviewing and revising the method of sale proposal during the meeting, the USNWG voted 12 to 1 to 

recommend to the NCWM L&R Committee that the proposal be presented for voting. The USNWG recognized that 

some members need to further vet the revised proposal within their organizations, but expects this process to be 

complete within the next few weeks. Any changes would be forwarded to the L&R Committee in time for inclusion 

in NCWM Publication 16. The USNWG will continue its review of the device code at its next meeting, which will be 

scheduled via web conference in the near future.

During the meeting, a subcommittee to develop methods and equipment needs for field testing EV charging 

devices was also formed.

Input Needed:

The USNWG encourages review and input on the draft MOS proposal as well as the draft device code.

Industry Letter to NCWM and L&R Committee

Amendment to 232-5 – Section 2.XX. Retail Sale of Electricity/Vehicle

On behalf of a coalition of industry stakeholders1

, I offer an amendment to the text contained in

Publication 16 (beginning on page L&R 32). 

This same coalition submitted a letter to the L&R Committee on 12 July 2013 (see Appendix 

A). Committee members should not interpret Friday’s letter as an endorsement of 232-5 

as printed in Publication 16.

In fact, the coalition letter was written with the understanding that the 11 June 2013 version of 

the draft uniform regulation would be considered today. That version reflects the most recent 

work of the NIST U.S. National Work Group on Measuring Systems for Electric Vehicle Fueling 

and Submetering (NIST National Work Group). 

Specifically, the NIST Status Report dated 19 June 2013 states:

Based on the results of this vote, the USNWG recommends that the 

NCWM L&R Committee replace the proposal in the 2013 Publication 

16 L&R Interim Meeting Report Item 232-5 with the following prior to voting 

on the item at the NCWM. (Appendix B) 

Many of the industry stakeholders cited below are a part of the NIST National Work Group and 

have been active participants throughout the language development process. 

In its most recent meeting on June 11, the NIST National Work Group amended the language 

contained in Publication 16. Our group of industry stakeholders was and is supportive of the 

amended version (Appendix B). 

The amendment I offer today is to replace what is contained in Publication 16 with the language 

approved by the NIST National Work Group at its June 11 meeting. 

This language can be found on page 3 of Appendix B.

Ms. Judy Cardin, Chair 

Laws and Regulations Committee

National Conference on Weights and Measures

1135 M Street, Suite 110 

Lincoln, Nebraska 68508 

Dear Chair Cardin:

The undersigned write to express our support for the revisions to NIST Handbook 130 

recommended by the U.S. National Work Group on Measuring Systems for Electric Vehicle 

Fueling and Submetering (USNWG) pertaining to method of sale.

We appreciate the opportunity to share with the Laws and Regulations (L&R) Committee the 

viewpoint of industry stakeholders. We believe that the sustainable adoption of electric vehicles 

(EV) requires the deployment of commercially viable electric vehicle supply equipment (EVSE). 

Many of our companies and organizations actively participated in the USNWG’s deliberations. The

dialogue allowed many different voices to be heard and complex questions to be discussed and 

clarified. The staff at NIST and all participants should be commended for their efforts in 

developing this recommendation for the L&R Committee. 

Both industry and the consumer segment represented in the USNWG supported the language as 

submitted by the USNWG to the L&R Committee. The recommended language enables multiple 

business models for providing electric vehicle charging services, which, consistent with national 

energy policies, will increase the availability of convenient charging facilities by promoting more

widespread adoption of EVSE.2 This also puts the EV driver in control of his or her recharging 

needs. 

By allowing for other appropriate business models in the case of charging services offered to 

consumers through retail sales methods based on non-energy units (2.XX.2.2), Electric Vehicle 

Service Providers (EVSP) are not precluded from offering recharging services based on mileage,

membership, time, place or other factors. Importantly, approximately 80% of the states do not 

permit the resale of electricity and these other business models enable the adoption of electric 

vehicle charging stations in those markets. 

At the same time, the proposed regulation also allows for a method of sale for those EVSP who 

wish to price their services based on the quantity of electricity delivered to the customer. 

The services that have formed around recharging an EV are still in their early stages, with market 

participants offering many different types of recharging services. Innovative companies are

providing great value to the EV driver in ways that bear little resemblance to the gasoline

2 See U.S. Department of Energy, One Million Electric Vehicles by 2015, February 2011 Status Report (noting 

“Uncertainties about EVs– including their resale value, range and availability of convenient charging facilities -- may

impose sales barriers.”). Available

station model. Recharging an EV is an entirely different experience in areas such as where, how 

long, and how often recharging takes place and the many new communication features

available between the vehicle, the EVSE, the EVSP, and the driver. 

This is why we had been concerned with earlier versions of the draft regulation that appeared to 

be largely based on the existing uniform regulation for petroleum-based fuels. Requiring that 

“all electrical energy kept, offered, or exposed for sale and sold at retail as a vehicle fuel shall 

be in units in terms of the megajoule (MJ) or kilowatt-hour (kWh)” would stifle innovation in this 

market sector, require a submeter on each and every EVSE, and drive up the cost of these 

products in an industry that is still seeding the market. 

Moreover, there is no additional consumer protection benefit to adopting an overly restrictive 

method of sale, because today’s technology enables customers to know vast amounts of 

information about the charging of their vehicles.

On June 11, when the USNWG voted favorably to report this draft regulation to the NCWM, nearly

all votes against the draft regulation came from members of the NCWM. At the same time,

virtually all other participants cast a vote for the draft regulation. We hope this letter gives the L&R 

Committee a clear view of the reasons behind our support. 

We, the undersigned, share the goal of creating a market that offers maximum choice and 

minimum cost to the EV driver. We believe a draft uniform regulation which preserves competition 

and innovation will help to achieve this goal. 

We urge the L&R Committee to approve this draft regulation. Sincerely,

[6/19/13]

Group: NIST U.S. National Work Group on Measuring Systems for Electric Vehicle Fueling and 

Submetering 

(USNWG EVF&S)

Scope and Purpose: In August 2012, NIST formed the USNWG EVF&S to develop proposed requirements 

for commercial electrical energy-measuring devices (including those used in submetering electrical 

energy at residential and business locations and those used to measure and sell electrical energy 

dispensed as a vehicle fuel) and to ensure that the prescribed methodologies and standards facilitate 

measurements that are traceable to the International System of Units (SI). This work is not intended to 

address utility metering in the home or business where the metered electricity is consumed by the end 

purchaser and that falls under the authority of entities such as the local utility commission. 

Membership: USNWG members include representatives from:

o vehicle charging equipment and electric meter manufacturers,

o State and local weights and measures jurisdictions, 

o energy distribution companies and service providers,

o national laboratories,

o technical committees (e.g., the ANSI C12 Chair),

o standards organizations (i.e., UL and NEMA), 

o NIST OWM and NIST Smart Grid Interoperability Panel. 

Meetings:

The USNWG has met a total of five times. 

In November 2012, NIST OWM prepared and distributed to the USNWG draft proposals for a method of 

sale (MOS) regulation (for inclusion in NIST HB 130) for electric vehicle refueling and a device code (for 

inclusion in NIST HB 44) that addresses both electric vehicle refueling and submeter applications. 

At its January 15-17, 2013 meeting, the USNWG voted 12 to 1 to recommend to the NCWM L&R 

Committee that the proposed new HB 130 MOS regulation be presented for a vote during the July 2013 

NCWM. The MOS proposal addresses: (1) method of sale; (2) unit price display; (3) identification of the 

service levels; (4) additional fees connected to charging; (5) device labeling; (6) street signs and other 

advertising; and (7) related definitions. 

Following the January meeting, USNWG members provided comments and suggested changes after 

vetting the HB 130 MOS proposal within their organizations. 

At its June 11, 2013 meeting, the USNWG discussed modifications to its original HB 130 MOS proposal:

1. A modified proposal based on those comments which had been received between January 28, 

2013 and May 30, 2013 that might be considered “minor” changes was repared for the USNWG

to consider during its June 2013 meeting. These suggested “minor” modifications were 

intended to: 

• Clarify that the MOS does not apply where no fees are associated with the delivery or 

distribution of electrical energy. 

• Reword the definition of the term Electrical Energy Sold as Vehicle Fuel to enhance 

clarity. 

• Remove the option to display the unit price in tenths of one cent and require that the 

unit price be display only in units of whole cents.
L&R Committee 2013 Final Report

Appendix D – Item 232-5: Uniform Regulation for Method of Sale of Commodities

L&R - D12

• Include wording to clarify that the labeling and signage requirements for communicating the

terms of “variable service” are intended to apply only to those conditions affecting service 

which are “under the direct control of the seller.” 

• Include the requirement that the display of any additional fees shall also include the 

basis for those fees. 

• Clarify that EVSE products shall be listed with a nationally recognized test laboratory

(NRTL) and shall be “installed” (instead of merely being “labeled”) in accordance with 

the National Electric Code (NEC).

• Recognize that street signs and advertising may appear either directly on or “in close

proximity to” an EVSE.

The USNWG did not vote on this version, but proceeded to discuss and vote on the amendment to

the scope described in Item 2 because members disagreed on the scope of the MOS.

2. During the meeting, an alternate proposal was made to modify the scope of the MOS to allow 

more than one method of sale. The proposed alternative would not require disclosure of the 

quantity of the electrical energy delivered to a consumer, as is currently provided when purchasing 

electrical energy from a utility or through submetering applications. Specifically, the proposal was

to add the following language to paragraph 2.XX. Retail Sales of Electrical Energy Sold as a Vehicle 

Fuel: 

This section does not apply to sales of electric vehicle charging services where 

the electric vehicle user is provided unlimited access to electric vehicle charging services

or where the electrical energy is free, as in the case where the fee assessed is 

wholly independent of the quantity of electrical energy delivered.

The amendment to modify the scope of the application of the MOS was adopted based on the 

results of the voting on the amendment shown below.

Alliance of Automobile Manufacturers Statement

Re: Gasoline Octane De-rating for High Altitudes

My name is Valerie Ughetta, and I am Director for Automotive Fuels at the Alliance of 

Automobile Manufacturers. The Alliance is the leading advocacy group for the auto industry, 

representing 77% of all car and light truck sales in the United States. Members include BMW 

Group, Chrysler Group LLC, Ford Motor Company, General Motors Company, Jaguar Land 

Rover, Mazda, Mercedes-Benz USA, Mitsubishi Motors, Porsche, Toyota, Volkswagen Group of 

America, and Volvo Cars North America. Our website can be found at www.autoalliance.org. 

Alliance Members strongly support a review of national consensus standards with regard to 

provisions that allow so-called Octane De-rating for Altitude. Without exception, all automakers 

specify the use of gasoline with a minimum octane rating of 87 AKI (Antiknock Index) in their 

vehicle owner’s manuals. Today, post- MY 1984 vehicles are designed, calibrated, and 

durability-tested to run on 87 AKI or higher fuel. 

A gasoline’s octane rating is the number one fuel property affecting a vehicle’s performance. 

Fuel is not merely a customer commodity, but an integral part of the vehicle system as a whole. 

Highly advanced fuel delivery, engine control and exhaust after-treatment systems are designed 

to run in a precisely engineered and optimized manner to meet challenging new environmental, 

fuel economy, and vehicle performance specifications. Engineering to protect against the 

potential use of a low octane fuel in a vehicle developed for 87 AKI or higher reduces the 

optimized functional capabilities of the vehicle. In short, consumers already need, and will 

continue to need nationally consistent supplies of minimum 87 AKI and higher rated octane 

fuels. 

Efforts at ASTM and NCWM to review their gasoline specifications and standards are important 

and time-sensitive. States neighboring the ASTM High Altitude designated geographic areas are 

faced with supply, marketing, and competitive issues because of the disparity in fuel grades from 

high altitude states and counties, because they get their gasoline from the same limited refinery 

and pipeline sources. This has been playing out in South Dakota over the past year. A uniform, 

national minimum octane grade is warranted by the refinements in vehicle technology and is far 

preferable for consumers to a patchwork of state laws. 

Thank you for the opportunity to comment.

L&R - E7 

My name is Win Gardner, Fuels Quality Manager for ExxonMobil in the US. We consider the proposal to 

amend Section 2.1.4 to eliminate the altitude adjustments for octanes to be premature at this time and 

recommend that the item remain informational.

ASTM is also addressing this issue and a ballot to remove the discussion regarding altitude adjustments 

was issued last fall and addressed at the December meeting. There were a number of negatives 

submitted for a variety of reasons, but predominantly because there was almost no pertinent data 

presented that the octane requirement adjustment for altitude was invalid. It was decided to withdraw 

the ballot and, instead, move forward with some scientifically designed experiments to elucidate the 

subject. 

Let’s take a look at what data is available. There are two types of data that should be considered. 

There’s the sort of data developed via designed experiments, exemplified by CRC studies which have 

been used traditionally to guide the specification setting process at ASTM. While there have been no 

recent CRC studies on the subject of octane requirement needs of vehicles at higher altitudes, there are 

a number of peer reviewed scientific studies that have been published using vehicles produced during 

the 1990s and 2000s which confirm that an altitude adjustment for octane is still justified. These studies 

were conducted with many vehicles employing altitude compensation. So the data that is available, 

while not conducted on the most recent model years, does conclude that vehicles operating at high 

altitudes require a lower octane than vehicles operating at sea level.

But there’s another type of data that’s available, empirical data, or that type of data developed over 

time from practical experience. As a general rule, I prefer the data that’s generated via scientific 

experiments. But empirical data isn’t automatically invalid and one shouldn’t discount it especially 

when there’s a wealth of it available. Gasoline with octanes at 85 or 85.5 has been sold in the mountain 

states of Montana, Idaho, Wyoming, Utah, Colorado and South Dakota for many decades. Consumers 

express their satisfaction with those grades by purchasing it overwhelmingly compared with the other 

octane grades available. The majority of the gasoline sold in the mountain states is Regular 85 or 85.5. 

We are a major marketer of these gasolines and have received no complaints from our customers about 

the octane over the years. And, to our knowledge, the auto manufacturers have not incurred octanerelated warranty issues on vehicles from this region.

While most of the sales in the mountain states are the Regular 85 grade, ExxonMobil and other 

companies do offer higher grades of 87 and 91 octane. So, if the auto companies choose to introduce 

more vehicles with turbo chargers or other technologies which require higher octane levels, those fuels 

are readily available at the same services stations.
L&R Committee 2013 Final Report

Appendix E – Item 237-2: Uniform Engine Fuels and Automotive Lubricants Regulation

L&R - E8 

I need to mention one other aspect of this issue. Octane isn’t free.

I’m sure you’ve noticed that Premium gasoline costs more at the pump than does Regular. In my area of 

the country the differential is about 50 cents. A refinery, given their crude mix and processing 

capabilities, has a limited octane “pool” to disburse among its gasoline products. Raising the octane of a 

product that represents the majority of production is not easy, nor cheap. MSAT (Mobile Source Air 

Toxics) II recently was implemented nationwide. This EPA program required that the levels of benzene 

be lowered in gasolines. Benzene has high octane so removing it from the gasoline pool reduced the 

ability to maintain octane. Fortunately, the rapid increase in ethanol blending counteracted that 

decrease due to MSAT II. If a significant increase in octane is mandated in the mountain states, we 

expect that refineries will have to invest many millions of dollars to modify their processing units. Those 

modifications take several years to plan, permit and construct, so any rapid change to regulated octanes

is likely to drive supply shortage issues and pressures on the cost structure. Do you really want to saddle 

the mountain state consumers with increased gasoline costs with essentially no data driven reason for 

their sacrifice?

Thank you for the opportunity to provide this testimony today. I recommend this item be maintained as 

informational pending ASTM action.

Ford Motor Company Statement

Re: Gasoline Octane De-rating for High Altitudes

Ford Motor Company supports the review of industry gasoline standards that allow marketers to 

sell fuel with an octane rating below 87 (R+M)/2 as “REGULAR GRADE”. The industry 

practice of de-rating the octane of fuels in altitude regions is not consistent with minimum octane 

requirements of vehicles manufactured by Ford that are designed and calibrated to operate on 87 

(R+M)/2 minimum octane at both sea level and higher altitudes. 

The recommendation given in Ford’s vehicle owner guides specifies that “Fuels with octane 

levels below 87 are not recommended.” In addition, the use of such fuels may result in loss of 

vehicle performance and possible engine damage that may void warranty claims for related 

repairs. 

In the mid 90’s, Ford raised concerns at industry meetings and held discussions with oil 

companies regarding a higher rate of warranty claims that were experienced by vehicle owners in 

altitude regions of western states, including, the Denver area. The rate of warranty claims related 

to spark knock complaints in Ford trucks were significantly higher in the altitude regions as 

compared to areas at sea level. Also, studies conducted by the Coordinating Research Council 

and findings reported in SAE papers in late 80’s confirmed that Ford vehicles and others had the 

same octane requirement, regardless of altitude. 

The discussions at NCWM to review the octane issue and develop a consensus on a minimum 

octane standard where “REGULAR GRADE” is defined as 87 (R+M)/2 would help the auto 

industry meet national standards for emission, fuel economy and GHG. A consensus on a 

minimum octane standard that is applicable to all regions of each state will also promote 

improved customer satisfaction for vehicle owners as it relates to vehicle performance and 

durability.

October 15th, 2012 questions – Response on 1-22-2013 by Richard Davis

Questions regarding the Plate Dimension Tester, submitted by David Sefcik, following the Southern W&M 

meeting.

Below are some thoughts and considerations regarding the proposal. We support your efforts and for 

bringing this modern equipment and specification improvements to our current test methods. 

Let me know if it would be possible to borrow or bring one of the devices to try out and demonstrate at 

the Interim? 

• The statement in the video to “take the shorter of the two measurements” may raise some 

questions. When dimensional testing is done on other products, and variations are found, 

inspectors are taught to take several readings and then the average. Also with dimensional 

testing, inspectors are taught to take a minimum 3 measurements, then average. This allows for 

reasonable variations (e.g., in addition, in 4.5 c, Step 2, it states that if the dimensions vary, that 

at least 10 items from each package should be measured. Measure and average the dimension.) 

o The point is well taken. We use the shorter of the two dimensional readings as a very 

conservative measurement. However, we have considered your comment and have 

altered the test method such that the plate dimension will be recorded as the average 

of the two 90 degree measurements. As to the number of items to be tested, we leave 

that to the circumstances of the testing purpose as described in an appropriate 

sampling and testing scenario. When testing on the production line, 1 sample may be 

enough to verify the process is lined out, but sampling a lot, delivery, or shipment may 

be quite a different case. The test method shows how to conduct the test, the sampling 

procedure should address the sample size required – so we did not specify it. 

 

• For weights and measures enforcement, the (stationary) rulers will have to be certified by a 

state metrology laboratory, so they should be removable for certification, re-certification, or 

replacement. Is there also a metric ruler? Making them removable will enable metric (SI) 

measures to be used. 

o Based on the placement of the rulers in an indented groove of the tester, they should 

not have stress on them to require re-certification; however, they are removable so 

they could be recertified if desired. The calibration block is also certified and intended 

to be used to verify no change in the rulers. It can be recertified as needed as well. 

• The 6 inch block in the video provides a means to only verify 1 graduation on the ruler. Are 

there plans to have different blocks available suitable to different size plates (i.e., 10 

inch)? Regardless, weights and measures will verify all of the graduations before use, but it 

wouldn’t hurt reliability if you were testing for example, 10 inch plates, to be able to do a quick 

verification of the graduation at that point too. 

o Our feeling is - if the rulers are certified and can be recertified if necessary, and the 

block is also certified, then if you can validate any one point on the certified ruler as 

being accurate, the whole ruler should be accurate. You therefore would not need two 

certification blocks.

• The current test procedure in the Note in 4.5 a, states: “do not distort the item’s shape during 

measurement”. Placing a weighted disk on the plate may be viewed as a distortion. You may 

want to elaborate on how the determination of the proper weight of the disks was arrived. The 

specifications for the discs are important because pressing down on the plates can distort the 

product as some plates are pretty flimsy, so there needs to be some guidance on how much 

weight the industry wants for different plates. The plate in the video appeared to be fairly rigid 

but others in the marketplace are not so sturdy.

o We conducted a series of testing scenarios to test whether or not a single weight of disk 

was appropriate. We used a variety of products (paper, foam, and molded pulp) to 

show that the one weight was sufficient for testing a wide range of products. We have 

submitted data to show our findings. We remain confident that the 225 gram weights 

are sufficient to be used across the broad range of products. 

• You may want to describe more about how the increased usability of this device can be used to 

accommodate a greater number of products such as napkins, paper towels, plastic plates, 

sandwich bags, etc... so that its cost can be better justified. For paper towels you may want to 

include a piece a Plexiglas that can be used to flatten and help take out creases of flat paper 

products (napkins).

o We have not addressed the use of this device for anything other than disposable plates, 

bowls, and platters. It may be possible to adapt it for other products but we have not 

taken the time and resources to do that. Potentially a good idea, but one that hasn’t 

been explored at this time. 

• You will likely be asked and need to include the specifications to build the device as part of 

HB133 test procedure. States may choose to build the device themselves or have another 3rd

party do it. It needs to be available for all and not a reliance on one manufacturer. This is 

generally accomplished by providing the specifications right in the Handbook.

o The engineering drawings were included in the original submission to the Southern 

Conference. Based on some of the feedback we received from you and others, we 

made a couple minor changes so the new drawings will also be available to the 

Conference if anyone chooses to build their own devise.

Report of the 

Specifications and Tolerances (S&T) Committee

Mr. Kenneth Ramsburg, Committee Chair

Maryland Weights and Measures

300 INTRODUCTION

This is the final report of the Committee on Specifications and Tolerances (S&T) (hereinafter referred to as the 

“Committee”) for the 98th Annual Meeting of the National Conference on Weights and Measures (NCWM). The 

report is based on the Interim Report offered in the NCWM Publication 16, “Committee Reports,” testimony at 

public hearings, comments received from the regional weights and measures associations and other parties, the 

NCWM 2013 Online Position Forum, the addendum sheets issued at the Annual Meeting, and actions taken by the 

membership at the voting session of the Annual Meeting.

Table A identifies the agenda and appendix items. The agenda items are identified in the report by Reference Key 

Number, Item Title, and Page Number. T he item numbers are those assigned in the Interim Meeting agenda. 

Voting items are indicated with a “V,” or if the item was part of the Voting Consent calendar by the suffix “VC” 

after the item number. Items marked with an “I” after the Reference Key Numbers are Information items. Items 

marked with a “D” after the Key Numbers are Developing items. The Developing designation indicates that an 

item, while it has merit, may not be adequately developed for action at the national level. Items marked “W” have 

been withdrawn from consideration. Items marked with a “W” will generally be referred to the regional weights and 

measures associations because they either need additional development, analysis, and input or did not have sufficient 

Committee support to bring them before the NCWM. T able B identifies the acronyms for organizations and 

technical terms used throughout the report, and Table C provides a summary of the results of the voting on the 

Committee’s items and the report in its entirety.

This report contains recommendations to amend the National Institute of Standards and Technology (NIST) 

Handbook 44, 2013 Edition, “Specifications, Tolerances, and Other Technical Requirements for Weighing and 

Measuring Devices.” Suggested revisions are shown in bold face print by striking out information to be deleted 

and underlining information to be added. N ew items proposed for the handbook are designated as such 

by underscored bold face print, and nonretroactive items are indicated in italics.

Note: The policy of NIST is to use metric units of measurement in all of its publications; however, 

recommendations received by the NCWM technical committees have been printed in this publication as submitted. 

Therefore, the report may contain references to inch-pound units.

the scale. The nominal capacity of a scale with more than two sections shall not exceed twice its rated section 

capacity. The nominal capacity of a two section scale shall not exceed its rated section capacity.* The 

nominal capacity marking shall satisfy the following: 

(a) For scales manufactured from January 1, 2002, through December 31, 2013: 

(1) The nominal capacity of a scale with more than two sections shall not exceed twice its 

rated section capacity. 

(2) The nominal capacity of a two section scale shall not exceed its rated section capacity.

(b) For scales manufactured on or after January 1, 2014, the nominal scale capacity shall not 

exceed the lesser of:

(1) The sum of the Weigh Module Capacities as shown in Table S.6.4.M. or Table S.6.4, or;

(2) Rated Sectional Capacity (RSC) multiplied by the Number of Sections (Ns) minus the 

Number of Dead Spaces (Nd) minus 0.5. As a formula this is stated as RSC × (Ns - Nd - 

0.5); or

(3) 290 300 kg (640 000 lb).

(Table Added 2013)

2. Add the following definition for the term “weigh module” to NIST Handbook 44, Appendix D:

weigh module – The portion of a load-receiving element supported by two sections. The length of a 

module is the distance to which load can be applied. [2.20]

Background/Discussion:

The nominal capacity of a railway track scale has historically been based on the capacity of the pivots or load cells

supporting the various sections of the scale. Since pivots were generally the weakest element, this was logical. 

With the introduction of load cell technology, the capacity of a section could far outreach the capacity of the 

weighbridge. W eighbridge design, based on the requirements in the AAR Scale Handbook, must be capable of 

supporting 80 000 lb axles on five foot centers. With the introduction of combined short span weigh modules over 

multiple sections, the use of the section capacity to determine scale capacity provides both the opportunity for 

overloaded structures and/or the requirement to overdesign the section. Basing nominal scale capacity on both the 
S&T Committee 2013 Final Report

S&T - 8 

section capacity and the structural capacity is the best solution. Additionally, a 640 000 lb limit assures these scales 

can be calibrated with 12.5 % of capacity using the conventional 80 000 lb test weight equipment.

The changes to the nominal capacity specification were developed by Committee 34 - Scales, of the American 

Railway Engineering and Maintenance-of-Way Association (AREMA) and approved, by unanimous vote, for 

inclusion in the AAR Scale Handbook. 

The original proposal to amend paragraph S.6.4. Railway Track Scales recommended: 1) striking out the two 

nonretroactive sentences in the paragraph, which linked nominal capacity to the number of sections of a railway 

track scale, and 2) adding new criteria for establishing a scale’s nominal capacity based on the lessor of three 

considerations as follows:

1. the sum of the weigh module capacities; 

2. a scale’s rated sectional capacity multiplied by the number of sections of the scale minus the number of 

dead spaces minus 0.5; or

3. 640 000 lb. 

The original proposal also recommended adding a new definition for “weigh module” and a new Table S.6.4. to 

NIST Handbook 44. The new table provided various capacity ratings of weigh modules based on weigh module 

length for use in determining the value of the first of the three considerations shown above. 

Eliminating the two nonretroactive sentences in the paragraph as proposed would have had the effect of making the 

entire paragraph retroactive. 

A number of significant changes to the original proposal were agreed to by the Committee relative to this item 

during the 2012 NCWM Interim and Annual Meetings as follows:

• During the Interim Meeting, the Committee agreed to add “the nominal capacity listed on the CC” to the 

list of proposed nominal capacity considerations to address concerns about the potential impact the 

proposal might have on existing equipment, especially equipment manufactured between the dates 

January 1, 2002, the effective date of enforcement of the nonretroactive portion of the current paragraph 

proposed for deletion, and the date the proposed changes to the paragraph would take effect. The 

Committee later agreed, during the Annual Meeting, to reverse that decision based on a concern expressed 

by OWM that if an NTEP CC corresponding to existing equipment were changed, that equipment may not 

be able to comply with proposed option of “the nominal capacity listed on the CC.” As an alternative, the 

Committee agreed to divide the proposal into two parts assigning each part a different enforcement date. 

• The Committee agreed, during the Interim Meeting, to amend the definition of “weigh module” originally 

proposed by deleting the words “single or articulated” as a descriptor in the definition. The Committee 

later agreed at the Annual Meeting to further modify the proposed definition by deleting the words “of the 

weighing element” from the proposed definition. 

• The Committee also agreed to add a n ote beneath Table S.6.4. Railway Track Scale – Weigh Module 

Capacity to make clear that the module capacities are to be based on the length of the module and 

corresponding capacities specified in the proposed table. 

Additionally, OWM commented during the 2012 NCWM Annual Meeting that they would likely include equivalent 

SI values in NIST Handbook 44, if the item were adopted. 

In consideration of the number of changes made to the item over the course of the two meetings, the Committee 

agreed to delete the proposal under Item Under Consideration in 2012 NCWM Publication 16 and replace it with the 

following:

During the fall 2012 Regional Association Meetings, the CWMA and SWMA supported the item and recommended 

it be designated a Voting Item. T he WWMA and NEWMA recommended it be an Information Item. 

Mr. Darrell Flocken (Mettler-Toledo, LLC), speaking on behalf of the SMA at both the WWMA and SWMA fall 

2012 Regional Association Meetings, stated that the SMA supported the concept of the more recent changes that 

took place during the course of the 2012 NCWM Annual Meeting and would review the item at its November 2012 

meeting. 

See the 2012 Annual Report to review previous language and positions to amend NIST Handbook 44 Scales Code 

paragraph S.6.4.

During the 2013 NCWM Interim Meeting Open Hearings, Mr. Flocken, speaking on behalf of the SMA, supported 

the item.

NIST OWM recommended three additional changes to the proposal as follows: 

1. Add a reference to Table S.6.4.M. in proposed new subparagraph S.6.4.(b)(1); 

2. Delete the words “the quantity of” from proposed new subparagraph S.6.4.(b)(2) so that it reads as follows: 

Rated Sectional Capacity (RSC) multiplied by the quantity of the Number of Sections (Ns) minus the 

Number of Dead Spaces (Nd) minus 0.5. As a formula this is stated as RSC × (Ns - Nd - 0.5); and 

3. Add the metric equivalent of 640 000 lb to proposed new subparagraph S.6.4.(b)(3). 

Mr. Rafael Jimenez (Association of American Railroad Transportation Technology Center), speaking on behalf of 

the AAR, and Mr. Steve Beitzel (Systems Associates, Inc.), supported the item with the changes suggested by 

OWM. 
S&T Committee 2013 Final Report

S&T - 11

Based on the comments received during the Open Hearings, the Committee agreed to amend the proposal to include 

OWM’s three suggested changes to read as shown in the Item Under Consideration and designated the item as a 

Voting Item. 

During the 2013 NCWM Annual Meeting Open Hearings, the Committee received comments from Mr. Flocken, 

speaking on behalf of the SMA, and Mr. Jimenez, speaking on behalf of the AAR, both in support of the item. 

There were four positions posted on the NCWM 2013 Online Position Forum; three supported the proposal and the 

other was neutral to the proposal.

The Committee recommended the item be presented for a vote as shown in the Item Under Consideration. 

320-2 W Table 4 – Minimum Test Weights and Test Loads

Fairbanks Scales, Inc. (2013)

Purpose: 

Provide clarification regarding the minimum amount of test weights and test loads required for official tests of floor 

scales having nominal capacities of 3001 lb and greater.

Background Discussion:

Table 4. Minimum Test Weights and Test Loads specifies that the greater of 25 % of device capacity or 300 lb, as 

the minimum amount of test weight required for testing scales ranging in capacity from 301 to 3000 lb. The 25 % 

specified in Table 4 corresponds with the amount required by the shift test procedures described in subparagraph

N.1.3.7.(b), which allows, as an option, the shift test to be performed using a one-quarter nominal capacity test load 

centered as nearly as possible, successively, over each corner of the load-receiving element. 

There is inconsistency in minimum test weight requirements between Table 4 and paragraph N.1.3.7. for scales of 

other capacities. Consider a 10 000 lb capacity floor scale as an example. Table 4 requires a minimum of only 

12.5 % of scale capacity in test weights, which equates to 1250 lb. Subparagraph N.1.3.7.(b) requires 25 % of 

nominal capacity in test load, or in this example 2500 lb, to perform the shift test. The differences in these two 
S&T Committee 2013 Final Report

S&T - 12

requirements could become an issue in states that enforce NIST Handbook 44. There should be consistency in the 

minimum test weights required and the weights required in performing a shift test.

One could argue that the shift test can be performed using substitutions along with test weights. However, 

N.1.3.7.(b) can be interpreted as specifically defining “test loads” as “test weights” for the purpose of that 

paragraph.

At the fall 2012 NEWMA Meeting, it was reported that some believe this item would be a safety concern (because 

of the increased amount of test weight that would be needed to test such scales if this proposal were accepted). 

NEWMA suggested retaining the 12.5 % currently specified in Table 4 and stated that more information would be 

needed to support the item. NEWMA forwarded the item to NCWM, recommending it as a Developing Item.

During the 2013 I nterim Meeting Open Hearings, the S&T Committee heard comments from Mr. Lou Straub 

(Fairbanks Scales) recommending that the item be withdrawn because the changes proposed to Table 4 shown in 

Item Under Consideration, if accepted, would not solve the problem identified by the submitter as reported on 

NCWM Form 15. Using a 10 000 lb capacity floor scale as an example to illustrate his point, Mr. Straub explained 

that Table 4 requires a minimum of 1250 lb in test weight and that subparagraph N.1.3.7.(b) specifies that either a 

one-third or one-quarter nominal capacity test load be used to conduct the shift test, depending upon the position of 

the test load on the platform. One-quarter nominal capacity, the lesser of the two fractions specified in subparagraph 

N.1.3.7.(b) equates to 2500 lb on a 10 000 lb capacity. Thus, it appeared to the Fairbanks technician, who submitted 

this proposal, that there was a conflict in the amount of test weight required by Table 4 a nd subparagraph 

N.1.3.7.(b), to perform an official test. 

Mr. Straub further explained to the Committee that, whereas a one-third nominal capacity test load is explicitly 

defined as “test weight” in subparagraph N.1.3.7.(b), a one-quarter nominal capacity test load, which is also 

referenced in the same subparagraph is not. In reviewing past NCWM Conference Reports relating to paragraph 

N.1.3.7., he concluded that the one-quarter nominal capacity test load referenced in subparagraph (b) was purposely 

not defined because it was intended for that test load to be comprised of either all test weight or a combination of 

test weight and substituted material. By not defining the one-quarter nominal capacity shift test load as test weight, 

one could conduct a shift test on a 10 000 lb capacity scale using a combination of 1250 lb of test weight (i.e., the 

minimum amount of test weight specified in Table 4 for a 10 000 capacity scale) and a single substitution test load. 

That is, a substitution test load used in combination with the test weight could create a shift test load equal to 

2500 lb (one-quarter nominal capacity). T his being the case, there is no conflict concerning the amount of test 

weight required by the two NIST Handbook 44 requirements. 

Mr. Straub also indicated that another factor contributing to his recommendation to withdraw this item is the fact 

that paragraph N.1.3.7. does not, in any way, preclude someone from conducting the shift test using a one-quarter

nominal capacity test load comprised entirely of test weight. In conclusion, he suggested that the Committee may

want to consider adding a footnote to subparagraph N.1.3.7.(b) to make clear that the one-quarter nominal capacity 

test load can be comprised of either test weight entirely or a combination of test weight and substitution test loads. 

The Committee also heard comments from Mr. Darrell Flocken (Mettler-Toledo, Inc.), speaking on behalf of the 

SMA. Mr. Flocken indicated that the SMA was opposed to the item as written because they do not believe the 

agenda item aligns with the recommendation as written in the original NCWM Form 15. 

NIST OWM noted that it is only reasonable to expect that the amount of test weight specified in NIST Handbook 44 

for a shift test be not greater than the minimum amount of test weight required to certify a scale. R ather than 

proposing to increase the amount of test weight required to perform an official test on all scales having capacities 

between 3001 lb and 40 000 lb, OWM suggested that the submitter might consider amending the Item Under 

Consideration so that its impact would be limited to only those scales having been identified in the proposal as being 

of concern, that is, those having capacities between 3001 lb and 10 000 lb. Jurisdictions might also find this to be a 

more reasonable approach. With regard to the possibility that paragraph N.1.3.7. might be misinterpreted, OWM 

noted that the paragraph is very clear in defining one-third nominal capacity test load as “test weight.” 

In consideration of Fairbanks Scales’ recommendation to withdraw the item and SMA’s opposition to the item, the 

Committee agreed to withdraw it. The Committee also agreed that it was not necessary to add a footnote to
S&T Committee 2013 Final Report

S&T - 13

paragraph N.1.3.7.(b) to clarify that a one-quarter capacity test load could be comprised of either test weight entirely 

or a combination of test weight and substitution test loads because there is already a footnote in Table 4 defining the 

term “test load.” 

During the 2013 NCWM Annual Meeting Open Hearings, Mr. Flocken, speaking on behalf of the SMA, and 

Mr. Straub (Fairbanks Scales) supported withdrawing the item. OWM reiterated the comments it provided during 

the 2013 NCWM Interim Meeting. 

No further action was taken by the Committee at the 2013 NCWM Annual Meeting since the Committee had 

previously agreed to Withdraw the item. 

320-3 W T.N.3., Table 6. Maintenance Tolerances

(This item was withdrawn.)

Source: 

Michigan Department of Agriculture (2013)

Purpose: 

Provide additional guidance concerning the proper application of NIST Handbook 44, Scales Code, Table 6. 

Maintenance Tolerances. 

Item Under Consideration:

Amend Scales Code Table 6. Maintenance Tolerances as follows: 

Table 6.

Maintenance Tolerances

(All values in this table are in scale divisions)

Tolerance in Scale Divisions

1d 2d 3d 5d

Class Test Load in Divisions

I 0 - 50 000 50 001 - 200 000 200 001 +

II 0 - 5 000 5 001 - 20 000 20 001 +

III 0 - 500 501 - 2 000 2 001 - 4 000 4 001 +

III L 0 - 500 501 - 1 000 (Add 1 d for each additional 500 d or fraction thereof)

Note: 

In order to determine the number of divisions for any test load; divide the value of the mass standard 

being applied by the minimum division indicated by the scale. 

Example: If the scale has a minimum division of 0.1 g and a 1500 g mass standard is applied, the test load 

is equal to 15 000 divisions. 

Result: On a Class II scale with a test load between 5001 and 20 000 divisions indicates the tolerance is 

± 2 divisions or ± 0.2 g.

Background/Discussion: 

2012 CWMA Interim Meeting: Table 6 is located in NIST Handbook 44; however, the instructions for use are 

located in NIST Handbook 133. This amendment would aid service companies who may be unaware of NIST 

Handbook 133, or those technicians who may have been told what the tolerances are but not trained on how to 
S&T Committee 2013 Final Report

S&T - 14

determine those numbers. Based on suggestions from regulatory officials, the submitter’s original proposal was 

modified to add “d” to the column headings and to rewrite the new guidance as a note and include an example. 

CWMA supported the item as amended and forwarded it to NCWM, recommending it as a Voting Item. 

At the 2013 NCWM Interim Meeting, Mr. Darrell Flocken (Mettler-Toledo, Inc.), speaking on behalf of the SMA 

supported the item, but recommended:

1. That the term “mass standard” be changed to “test weight(s)” in both the “Note” and the “Example” 

sentences.

2. That the two sentences, the first of which follows the word “Example” and the second of which follows the 

word “Result” in the Item Under Consideration be combined as an example to read: 

Example: If the scale has A Class II scale with a minimum division of 0.1 g and a 1500 g mass 

standard test weight(s) is applied, the test load is equal to 15 000 divisions, resulting in a tolerance is

of ± 0.2 g.

Result: On a Class II scale with a test load between 5001 and 20 000 divisions indicates the tolerance 

is ± 2 divisions or ±- 0.2 g.

NIST OWM commented that it would be inappropriate to include the letter “d” after each tolerance multiple as 

shown in Table 6 of the Item Under Consideration because in cases where the value of d ≠ e (such as on some 

Class I and II scales, dynamic monorails, etc.) a factor of the value of “e,” rather than “d,” is used to determine the 

applicable tolerances. Likewise, in the proposed note and associated example, it would be technically incorrect, in 

some cases, to refer to the division as “minimum” because the minimum division indicated by the scale would be the 

value of “d” and “d” would not necessarily be used to determine the number of divisions for any test load. In cases 

where the value of d ≠ e, the number of divisions for any test load would be determined by dividing the test load 

value by the verification division (e). For these reasons, it is OWM’s opinion that the proposed changes would tend 

to confuse rather than aid those not very familiar with how the values in Table 6 are to be applied. 

Ms. Kristen Macy (California) commented that she agreed with OWM’s comments and that the changes proposed in

the Item Under Consideration would only apply in cases where the value of “d” and “e” are equal. 

NIST OWM developed the following alternative changes to Table 6 and provided them to the Committee for 

consideration should the Committee decide that additional clarification of the values in Table 6 were needed: 

Table 6.

Maintenance Tolerances

(All values in this table are in scale divisions)

Tolerance in Scale Divisions (d or e)*

1 2 3 5

Class Test Load in Scale Divisions (d or e)*

I 0 - 50 000 50 001 - 200 000 200 001 +

II 0 - 5 000 5 001 - 20 000 20 001 +

 III 0 - 500 501 - 2 000 2 001 - 4 000 4 001 +

III L 0 - 500 501 - 1 000 (Add 1 d for each additional 500 d or fraction thereof)

*In cases where d ≠ e, for example, some Class I and II scales, dynamic monorail scales, etc., the value 

of “e” is used to determine tolerance and test load. In all other cases the value of “d” is to be used. 
S&T Committee 2013 Final Report

S&T - 15

OWM noted that a somewhat different approach to amending Table 6 in an effort to improve understanding would 

be to develop and present a separate table in NIST Handbook 44 for each scale accuracy class. An example draft 

table for Class I scales was developed by OWM and also provided to the Committee to show how these could be 

used as an alternative to amending Table 6. 

The following additional comments and recommendations relating to the Item Under Consideration were also 

provided by OWM: 

• If a note is needed to explain how to calculate the number of scale divisions in the test load, OWM suggests 

expressing the example as a formula and offers the following for consideration:

Test Load in Scale Divisions =

ScaleofValue Division eord Unitsin Massof

Test Load Unitsin Massof

)(

• With regard to the proposed example, the Committee might wish to consider suggesting that the example 

be included in a field manual, EPO, or other guidance document, rather than in NIST Handbook 44.

• Should the Committee decide to modify Table 6 by adding additional clarifications concerning which value 

(“d” or “e”) applies, it might also consider amending various other paragraphs in NIST Handbook 44 where 

both (d) or (e) could apply, yet, neither is specified, or only one of the two is specified within the paragraph 

(e.g., paragraphs S.2.1.3.1, S.2.1.3.2., N.1.2.1., T.N.1.2., T.N.7.2., etc.).

In considering this item, the Committee agreed with the comments received from NIST OWM and the State of 

California that it would be inappropriate to include the letter “d” after each tolerance multiple without also including 

some explanation of how the values in the table would apply in cases where the value of “d” and “e” are different on 

a scale. The NIST Technical Advisor pointed out to the Committee that in the United States, the term “scale 

division” is often used interchangeably to reference both scale division (d) and verification scale division (e) and 

that, unless the term is further defined, it is unknown which value is being referenced. Adding the letter “d” after 

each tolerance multiple as proposed in the Item Under Consideration would provide additional clarification by 

defining the tolerance values as scale division (d) opposed to verification scale division (e). S uch clarification 

would be inappropriate because the tolerances in Table 6 must also be applied to scales having a value of “d” that is 

different than “e” and in such cases, tolerances must be determined in values of “e.” 

The Committee considered how the table might be amended or the information in the table presented to provide a 

better understanding of how tolerances are to be determined given that the table applies to not only scales where the 

value of “d” and “e” are the same, but also to scales where the values are different. The Committee considered 

OWM’s alternative changes to the table and whether or not a separate table in NIST Handbook 44 for each scale 

accuracy class would make it any easier for those less experienced to understand how to determine and apply 

tolerances. The Committee concluded that there is no simple means of making the information in the table easier to 

understand or presenting it in a way that would improve understanding for inexperienced inspectors or service 

personnel who have not received training. The Committee agreed that regardless of how the table was changed or 

the information in the table presented, training would still be needed to teach how the values in the table are to be 

applied. With training comes the understanding that “d” and “e” are not always equal for all classes of scales and 

how to use those values to determine the tolerance and test loads specified in Table 6. Additionally, the definition in 

Appendix D for “verification scale division” and paragraph S.1.2.2. Verification Scale Interval clarifies how “d” and 

“e” are to be applied. In considering OWM’s alternative approach of developing and presenting a table for each 

scale accuracy class, the Committee preferred that scale tolerances for all scale accuracy classes remain in a single 

condensed table. The Committee also agreed that examples to make clear how tolerances are to be applied are better 

included in training material rather than NIST Handbook 44. The Committee indicated that it understood and 

appreciated the concerns raised by the submitter of this item, but didn’t believe the changes proposed to NIST 

Handbook 44 would be beneficial, and, therefore, agreed to Withdraw this item. 

During the 2013 NCWM Annual Meeting Open Hearings, Mr. Flocken, speaking on behalf of the SMA, commented 

that the SMA opposes the withdrawal of this item and recommends the item be returned to an “Information” status 
S&T Committee 2013 Final Report

S&T - 16

because the SMA believes this item has value in clarifying the use of the information in the table. Once the item 

becomes “Informational,” the following changes should be considered:

1. Change the term “mass standard” to “test weight(s)” in both the “Note” and the “Example” sentences.

2. Combine the “Example” and “Result” sentences to read: 

Example: If the scale has A Class II scale with a minimum division of 0.1 g and a 1500 g mass 

standard test weight(s) is applied, the test load is equal to 15 000 divisions, resulting in a tolerance is

of ± 2 divisions or ± 0.2 g. 

Result: On a Class II scale with a test load between 5001 and 20 000 divisions indicates the tolerance 

is ±- 2 divisions or ± 0.2 g.

3. The actual tolerance value in Table 6 should not be identified as “d” because the verification scale interval 

for a Class I and II instrument is “e”.

4. Add the phrase “(as required by the Instruments Class designation)” after the words “Tolerance in Scale 

Divisions.” 

Ms. Julie Quinn (Minnesota) supported returning the item to “Informational” status commenting that Table 6 is very 

confusing and that service technicians, especially, have difficulty understanding the table. 

OWM reiterated the comments it provided during the 2013 Interim Meeting. 

In discussing this item during its work session, the Committee once again concluded, as it had at the 2013 Interim 

Meeting, that regardless of how the table was changed or the information in the table presented, training would still 

be needed to teach how the values in the table are to be applied. The Committee agreed that the best approach to 

resolving confusion over the application of the table is through training and examples provided in the NIST EPOs. 

The Committee decided to withdraw the item noting that its decision to do so would not preclude someone or group 

from proposing a new item to better clarify how the values in Table 6 are to be applied. 

320-4 VC Appendix C – Units of Mass (ton)

(This item was adopted.)

Source: 

Rice Lake Weighing Systems, Inc. (2012)

Purpose: 

Establish uniform abbreviations for “short ton.” 

Item Under Consideration: 

1. Amend the Units of Mass Table that appears on pages C-19 and C-20 of NIST Handbook 44 Appendix C to 

recognize “tn” as an acceptable abbreviation for “net” or “short” ton, and add a footnote to make clear that 

abbreviations for “net” or “short” ton other than “tn” are considered appropriate for use with older equipment.

Assign the appropriate footnote sequence number to “x” in the table and footnote shown above and renumber 

subsequent footnotes in Appendix C.

Background/Discussion:

The submitter of this item discovered a difference between United States and Canadian abbreviation requirements 

that may impact manufacturers that sell products in both countries and NTEP type evaluations under the United 

States/Canada mutual recognition program. Most units of mass have an abbreviation for SI and U.S. customary 

units (e.g., kg, lb, g, oz). However, the same abbreviation, the lower case “t,” is used to represent both the metric 

ton and the short ton (2000 lb). If an indicator is set up to display both SI and U.S. customary units, the operator or 

customer cannot know what units are being displayed if “t” is the only abbreviation that is acceptable for metric ton. 

Because of the limited space available on today’s indicators, the words “short ton” or “long ton” are not always an 

option.
S&T Committee 2013 Final Report

S&T - 19

In the Canadian Lab Manual, Part 2, Section Appendix-2A in the table for abbreviations and symbols accepted in 

Canada, metric ton is abbreviated by “t” and short ton is abbreviated by “tn.” I n NCWM Publication 14, 

Appendix C in a table titled “Acceptable Abbreviation/Symbols” there is an abbreviation of “TN” for short ton and 

“LT” for long ton. I n keeping with the Canadian abbreviation, the Committee considered a r equest that NIST 

Handbook 44 be amended to use the lower case “tn” and “lt” as the abbreviations for short and long ton respectively.

During the 2012 NCWM Interim Meeting, the original submitter, Mr. Paul Lewis (Rice Lake Weighing Systems, 

Inc.) requested that the proposal in the Interim Agenda be modified to remove the reference to “long ton” and its 

associated proposed abbreviation “lt.” Mr. Lewis indicated that the intent of the proposal is to align United States

and Canadian requirements and noted that the abbreviation “tn” is an acceptable Canadian abbreviation for “short 

ton.” The Committee agreed to remove the reference to “long ton” in the Units of Mass table on page C-19 of NIST 

Handbook 44, Appendix C as was requested by the submitter of the proposal. 

See the 2012 A nnual Report to review previous language and positions to recognize “tn” as an acceptable 

abbreviation for “net” or “short” ton in NIST Handbook 44.

Comments received during the Open Hearings of the fall 2012 Regional Weights and Measures Associations were

predominantly in support of the item. At the fall 2012 CWMA Interim Meeting, industry requested that the 

Committee support a ch ange to “short ton” to align with Measurement Canada. T he WWMA acknowledged 

potential conflict with the abbreviation of “tn” for “net” or “short ton” in NCWM Publication 14 BCS-4, yet 

reported there was no opposition to the item and it appeared that concerns raised in the Background/Discussion had 

been resolved. Mr. Darrell Flocken (Mettler-Toledo, Inc.), speaking on behalf of the SMA during the WWMA and

SWMA, indicated the SMA supported the item. T hree of the regional weights and measures associations 

recommended the item be Voting and NEWMA recommended it remain Informational. 

During the 2013 NCWM Interim Meeting Open Hearings, NIST OWM commented that conflicts in the abbreviation 

for “short” or “net” ton in NIST Handbook 44 and NCWM Publication 14 are of continued concern and noted the 

following:

• NIST Handbook 44 (Appendix C) recognizes the lower case “t” as an acceptable abbreviation for both the 

U.S. short ton and the metric ton. NIST Handbook 44 does not recognize upper case “T” as an acceptable 

abbreviation for the U.S. short ton or metric ton, nor does it recognize upper case “LT” as an acceptable 

abbreviation for the U.S. long ton. 

• A table included on page BCS-4 of the 2012 NCWM (NTEP) Publication 14, Belt Conveyor Scales (BCSs) 

Checklists and Test Procedures indicates the U.S. short ton may be identified as “ton” or upper case “T;” 

the metric ton as lower case “t;” and the U.S. long ton as upper case “LT.” The following abbreviations 

appear in the 2012 version of Pub 14 BCSs type evaluation criteria: 

Unit Abbreviation

pounds lb or LB

U.S. short ton ton or T

U.S. long ton LT

Metric ton t

kilograms kg

The word “ton” is not an abbreviation although it is included in the NCWM Publication 14 table as such. 

• Because upper case “T” and upper case “LT” are recognized by NTEP as acceptable abbreviations for U.S. 

short ton and U.S. long ton, respectively, it can only be assumed that there are BCSs currently in 

commercial service that have been issued an NTEP CC that use these abbreviations.
S&T Committee 2013 Final Report

S&T - 20

• By virtue of the fact that paragraph G-S.5.6.1. specifies the locations of where appropriate abbreviations for 

equipment manufactured as of January 1, 2008, may be found; if a particular defining symbol observed 

during inspection is not included in those locations, it infers that that particular symbol is inappropriate, 

disallowed, and would necessitate official rejection. Thus, if an official were to observe the abbreviation 

“T” or “LT” during an inspection of a BCS that was manufactured as of January 1, 2008, regardless of 

which “ton” was intended to be identified, they should reject for failure to comply with the provisions of 

G-S.5.6.1. even though an active CC may be linked to the device. 

• If the proposed change is adopted and “tn” was to become an acceptable abbreviation for U.S. “short ton,” 

Publication 14 BCSs would be revised to reflect the change. H ow will officials apply the revised

abbreviation to existing equipment that designate short tons using upper case “T” or other abbreviations? 

Wouldn’t accepting the additional abbreviation “tn” for the U.S. short ton only add to an already existing, 

and somewhat confusing problem? 

• A more reasonable approach it would seem, is to first fix the current problem, perhaps by agreeing on one 

or maybe two, acceptable abbreviations for each type of ton and then specifying what those agreed upon 

abbreviations are in both NIST Handbook 44 and NCWM Publication 14. Additionally, it might be agreed 

that when the word ton is not abbreviated, it must be further qualified by a preface clarifying which ton is 

being referenced. As OWM has noted before, even if everyone were to agree on different acceptable

abbreviations for the U.S. short or net ton, the U.S. long ton, and the metric ton, it would be unlikely that 

this would completely resolve all the confusion relating to the value of the ton in commercial transactions. 

The spelled-out version of the word “ton” is often used instead of its abbreviation to identify values 

displayed or recorded by a commercial device. Thus, unless the word “ton” is further qualified using an 

appropriate clarifying preface such as “metric,” “short,” “net,” or “long,” it’s unclear as to which ton is 

being referenced when the word “ton” by itself is used to identify the unit of measure. 

As a final comment, OWM recommended that, should the Committee decide to move forward with the proposal, the 

Committee should consider changing the abbreviation “t” (which refers to 1 t on (short), beneath the heading 

“Avoirdupois Units of Mass” on page C-6 of the 2012 version of NIST Handbook 44) to “tn” to avoid conflict with 

the recommended proposal. 

The submitter of the proposal, Mr. Lewis, commented that the intent of the proposal is to harmonize the abbreviation 

for “short ton” with Measurement Canada’s requirements. 

Mr. Flocken, speaking on behalf of the SMA, indicated that the SMA supported the item. 

During its deliberations, the Committee considered how to address concerns regarding how officials are to treat 

equipment with an existing CC that uses an abbreviation for short ton that differs from the “tn” abbreviation 

proposed, should this item be adopted. Paragraph G-S.5.6.1. specifies the locations of where appropriate 

abbreviations for equipment manufactured as of January 1, 2008, may be found and NIST OWM commented during 

the Open Hearings that if a particular defining symbol observed during inspection is not included in those locations, 

it infers that particular symbol is inappropriate, disallowed, and would necessitate official rejection. If “tn” is made 

the acceptable abbreviation for “short ton” and is added to Appendix C of NIST Handbook 44 as proposed, how are 

officials to apply paragraph G-S.5.6.1. to existing equipment that uses an abbreviation other than “tn” that was 

manufactured on or after January 1, 2008 [i.e., the enforcement date of G-S.5.6.1.(a)]? 

The Committee acknowledged that the change proposed, if adopted, would affect some existing equipment that use 

an abbreviation for short ton that might currently be considered acceptable, but with this change, would cause that 

abbreviation to be unacceptable. In consideration of this point, the Committee reported that they were interested in 

hearing input from those anticipating that this change would be detrimental to their equipment. 

The Committee agreed to designate this as a Voting Item and, in an effort to address the concerns raised by OWM 

regarding the treatment of existing equipment, to add a new footnote to Appendix C in the Units of Mass Table 

immediately following the abbreviation “tn,” as shown in the Item Under Consideration. 
S&T Committee 2013 Final Report

S&T - 21

The Committee also agreed with OWM’s suggestion to change the abbreviation “t,” which refers to “1 ton (short),” 

beneath the heading “Avoirdupois Units of Mass” on page C-6 of the 2013 version of NIST Handbook 44 to “tn” 

and add the same new footnote immediately following the amended abbreviation as shown in the Item Under 

Consideration. 

During the 2013 NCWM Annual Meeting Open Hearings, the Committee heard comments in support of the item 

from Mr. Flocken, speaking on behalf of the SMA, and Mr. Ripka (Thermo Fisher Scientific). 

OWM acknowledged that the footnote added by the S&T Committee during the 2013 Interim Meeting addressed the 

concern it had previously raised regarding how these abbreviations will be applied to existing as well as newly 

installed equipment. H owever, as noted before, should the proposal be adopted it w ill conflict with existing 

references in Publication 14; DES Appendix C includes references to “T” and “LT” as acceptable abbreviations. 

Thus, OWM encouraged each sector to review Publication 14 for any references to abbreviations for consistency 

with the proposed changes to NIST Handbook 44. The NIST Technical Advisors to the WS and BCS plan to ask 

those sectors to review Publication 14 f or consistency with the abbreviations proposed in the Item Under 

Consideration. 

OWM also expressed continued concern about the use of qualifying terms associated with the word “ton.” The 

spelled-out version of the word “ton” is often used instead of one of its many abbreviations to identify values 

displayed or recorded by a commercial device. U nless the word “ton” is further qualified using an appropriate 

clarifying preface such as “metric,” “short,” “net,” or “long,” it is questionable as to which ton is being referenced 

when the word “ton” by itself is used to identify the unit of measure. 

There were three positions posted on the NCWM 2013 Online Position Forum; one of which supported the proposal 

and the other two were neutral to the proposal.

The Committee recommended the item be presented for Vote as proposed.

320-5 I Part 2.20. Weigh-In-Motion Vehicle Scales for Law Enforcement – Work Group 

Note: This item was originally numbered 360-4 in the Committee’s 2013 Interim Report. This item was moved to 

the 320 Scales Section and renumbered 320-5 during the Committee’s Open Hearings. 

Source: 

NIST, OWM, Mr. Richard Harshman, on behalf of the U.S. Federal Highway Administration (FHWA) (2011)

Purpose: 

To provide the U.S. Weights and Measures community (equipment manufacturers, weights and measures officials, 

truck weight enforcement officials, and other users) with legal metrology requirements to address Weigh-in-Motion 

(WIM) systems used for vehicle enforcement screening. 

Item under Consideration: 

Adopt the proposed Section 2.25. Weigh-In-Motion Systems Used for Vehicle Enforcement Screening Code shown 

in Appendix B as a tentative code in NIST Handbook 44, and adopt the proposed definitions of terms used in the 

tentative code (also included in Appendix B) into NIST Handbook 44 Appendix D - Definitions. 

Background/Discussion: 

The Nation’s highways, freight transportation system, and enforcement resources are being strained by the volume 

of freight being moved and the corresponding number of commercial vehicles operating on its roads. Traditional, 

static-based vehicle inspection activities simply cannot keep pace with anticipated truck volume increases. Current 

U.S. Department of Transportation (DOT) forecasts project freight volumes to double by 2035 a nd commercial 

vehicles to travel an additional 100 billion miles per year by 2020. WIM technology has been targeted by FHWA 

and Federal Motor Carrier Safety Administration as a technology capable of supporting more effective and efficient 

truck weight enforcement programs. 
S&T Committee 2013 Final Report

S&T - 22

Several DOT efforts are underway and planned for the future to maintain adequate levels of enforcement that ensure 

equity in the trucking industry market and protection of highway infrastructure. Judicial support for enforcement 

decisions to apply more intense enforcement actions on specific trucks depends on support from the U.S. legal 

metrology community. Standards are needed in NIST Handbook 44 to address the design, installation, accuracy, 

and use of WIM systems used in a screening/sorting application. The implementation of a uniform set of standards 

will greatly improve the overall efficiency of the Nation’s commercial vehicle enforcement process. 

Once adopted by the truck weight enforcement community, these requirements will enhance the accuracy of the 

Nation’s WIM scale systems; serve as a s ound basis for judicial support of next-generation truck weight 

enforcement programs; and result in fewer legally loaded vehicles being delayed at static weigh station locations, 

thus reducing traffic congestion and non-productive fuel consumption and improving the movement of freight on 

our nation’s roadways.

Purpose of the Project: 

The FHWA’s Office of Freight Management and Operations recognized a need to encourage uniformity in the 

design, testing, installation, and performance of WIM technology and subsequently encourage acceptance by 

prosecution agencies (administrative or judicial) regarding the validity of WIM technology’s role in supporting 

commercial motor vehicle weight enforcement.

In response to this need and recognizing the value of having a standard included in NIST Handbook 44 because it 

lends integrity and is more recognizable in legal actions, the FHWA seeks to integrate WIM technology into the 

Handbook. The FHWA contracted the services of the Texas Transportation Institute—The Texas A&M University 

System and Battelle (a private company) to begin this process. Additionally, a small oversight Committee was 

formed by the FHWA, made up of three representatives from the FHWA, a NIST Technical Advisor, and a 

representative of a U.S. manufacturer of WIM equipment to validate that each contract deliverable is completed 

according to contract. NIST OWM agreed to provide a technical advisor to the associated work group tasked with 

development of the proposed code.

The intended application of the proposed new code is for screening purposes only (i.e., for screening/sorting 

commercial vehicles for possible violations of FHWA vehicle weight requirements). 

The dates and descriptions below under the heading “Timeline of Completed Tasks Relating to the Project” are 

intended to provide an updated summary on the progress of the project since its inception. 

Timeline of Completed Tasks Relating to the Project: 

December 2010: A detailed project work plan, intended to guide activities and establish lines of communication 

from project inception to project completion, is developed. At about this same time, the NCWM and the S&T 

Committee are contacted and made aware of the project. Members of the NCWM S&T Committee are invited to 

participate on the USNWG charged with developing WIM standards that is about to be formed. 

April 2011: A USNWG is established from the WIM stakeholder community comprised of representatives from 

state departments of transportation, state law enforcement agencies, weights and measures officials, WIM 

technology manufacturers and vendors, academic researchers, and others. 

July 2011: The USNWG holds its first face to face meeting. Mr. Darrell Flocken (Mettler-Toledo, Inc.) accepts the 

position of WIM USNWG chair, and encourages stakeholders to submit comments to the work group. During the 

meeting, Mr. Rick Harshman, (NIST OWM) Technical Advisor to the USNWG, presents an overview of the process 

to develop the technical content of a new WIM Code. He explains how NIST Handbook 44 is organized and how 

requirements developed by the USNWG will fit into the various sections of a new NIST Handbook 44 code. He 

also provided an overview of the standards development process and discusses the benefits of the USNWG using an 

example draft code, which he had already created to develop the new draft code. Mr. Steve Langford (Cardinal 

Scale Manufacturing Co.) gives a presentation on the NIST Handbook 44 amendment process, which detailed the 

various steps the USNWG will need to complete to add a new device code to NIST Handbook 44. 
S&T Committee 2013 Final Report

S&T - 23

Several concerns/questions are raised by participants during the open discussion portion of the meeting. T he 

following are some of the most important concerns/questions discussed:

• The application section of the code is critical. The types of WIM systems in which the code does and does 

not apply will significantly impact all other sections of the code. 

• What tolerance should be specified in the draft code? An important related question is: What degree of 

accuracy will the judicial system (courts) accept as being sufficiently accurate enough to screen 

commercial vehicles for possible overweight violations? The degree of accuracy required will have a large 

impact on the kinds of systems that get included or excluded in the application section of the code. 

• There needs to be a separation of requirements. That is, a separation of requirements that apply to virtual 

weigh stations and those that apply to WIM systems installed at weigh stations having a static scale.

• To adopt a d raft code at the national level, two things must happen: 1) A legitimate test procedure is 

needed to enable states to test these systems; and 2) federal funding is needed to help cover the cost of 

testing.

• Will NCWM Publication 14 type evaluation criteria be needed since these systems are not commercial and 

are unlike other devices typically covered by NIST Handbook 44? 

The USNWG agreed to discuss these concerns/questions and any others brought to their attention during their next 

meeting.

November 2011: The example draft code developed earlier by Mr. Harshman, along with a checklist developed by 

Mr. Flocken is distributed to members of the USNWG. Participants are asked to complete the checklist as they 

review the draft code, identifying sections within the draft code, which they believe need additional work. 

May 2012: The first working draft of a WIM Code is developed based on comments received from the draft code 

and checklist that had been previously distributed in November 2011. A separate draft document containing 

definitions of terms that may need to be added to Appendix D of NIST Handbook 44 is also developed. 

October 2012: Following a delay due to funding issues within the FHWA, the first working draft code and draft 

definitions are distributed to members of the USNWG for discussion at the next face to face meeting, which is

scheduled November 2012.

November 2012: The USNWG conducts their second face to face meeting. During the meeting, the first working 

draft WIM Code is reviewed, discussed, and revised. Members of the USNWG agree that the revised draft code and 

associated definitions should be submitted to the NCWM for review and comment. The revised draft and associated 

definition documents are forwarded to the Chairman of the 2013 S &T Committee and to the NCWM. N CWM 

agrees to post these documents onto its website and notifies members of their presence. 

See the 2012 Annual Report (S&T Agenda Item 360-3) for additional background information and summary updates 

of the 2012 Regional Weights and Measures Association Meetings and 2012 NCWM Meetings relating to this item.

2013 NCWM Interim Meeting Open Hearings: Mr. Flocken recommended that the Committee consider moving this 

item forward as an Information item so that it might be provided a greater level of consideration by the weights and 

measures community. Mr. Flocken reported that a new Draft WIM Code had recently been developed by members 

of the USNWG, and, although not perfect, the consensus of the USNWG is that it is ready for an initial review. 

There are two parts to the draft code, one of which is the draft code itself and the other is a document containing 

definitions of terms used in the draft code. Both have been posted and are available for review from the NCWM 

website. The USNWG is requesting feedback from the weights and measures community on both parts of the draft. 
S&T Committee 2013 Final Report

S&T - 24

Additional comments in support of the draft were heard during the Open Hearings from members of the FHWA’s 

Project Oversight Committee, the SMA, and a State of Florida DOT enforcement official. Based on the comments 

in support of this item, the Committee designates the item Informational. 

2013 NCWM Annual Meeting Open Hearings: Mr. Flocken, Chairman of WIM WG, gave an update on the 

development of the WIM draft code and clarified that its scope is strictly for screening purposes. 

OWM encourages further development of the draft code by the Weigh-In-Motion WG and offered the following 

feedback on the first draft: 

1. To ensure that test procedures are applied uniformly, the WG may want to consider including in the draft 

code procedures for establishing the reference weights of axle loads, axle-group loads, and gross vehicle 

weight. The WG may also want to consider specifying the types of scales considered acceptable for use in 

establishing such test loads and their acceptable degree of accuracy. Currently, Table T.3.1. of the draft 

code specifies tolerances for axle load, axle group load, and gross vehicle weight. It also specifies that 

these tolerances be based on a percentage of the applied test load. In order to apply these tolerances, test 

loads of known value for axle load, axle-group load, and gross vehicle weight need to be established in 

advance of dynamic testing of a WIM system using a reference scale suitable for making such 

determinations. Additionally, in accordance with NIST Handbook 44, Appendix A – Fundamental 

Considerations, the error and uncertainty of the test loads, if used without correction, must be less than 

one-third the applicable tolerance. The draft code does not provide an indication of the types of scales 

considered acceptable for making such reference weight determinations (e.g., vehicle, axle-load), or the 

procedures that are to be followed when using those scales to establish the reference weights. OWM notes 

that the accuracy of the reference scale used for determining gross vehicle weight seems to be adequately 

addressed in paragraph N.1.3. Reference Scale, which requires each reference vehicle to be weighed on a 

static scale meeting NIST Handbook 44 maintenance tolerances.

2. The WG may also want to consider including in the draft code specific requirements applicable to the 

design, installation, and maintenance of the approach and exit aprons of the weigh sensor(s) of a W IM 

system. O WM questions whether or not it’s possible to obtain accurate and repeatable axle-load, 

axle-group-load, and gross vehicle weight determinations from vehicle WIM systems without including 

such requirements. Such requirements are needed to filter out inconsistent forces such as the following:

• “Wheel hop” (or bounce) causes undesirable accelerated vertical forces to be applied to the weigh 

sensor(s) of a WIM system as vehicles to be weighed in motion pass over them. Such undesirable 

forces result when the tires of a vehicle to be weighed in motion pass over an irregular pavement 

surface on either side of the weigh sensor(s). 

• “Force transfer” is the transfer of applied force from one part of a vehicle being weighed in motion 

to another part. Such transfer of forces occur, for example, when individual axles or tandem axles 

of a vehicle are weighed individually and are not in the same plane (i.e., the vehicle being weighed 

is not level). 

During development of the draft code, the WIM WG agreed not to include specific requirements for aprons 

in advance of and beyond the load sensor(s), but rather, agreed to include the following language in 

paragraph UR.2. User Location Conditions and Maintenance to deal with this issue: “The system shall be 

installed and maintained as defined in the manufacturer’s recommendation.” While the draft code does 

include a user requirement intended to address this issue, the draft language alone is not sufficient enough 

to adequately address this important aspect of a vehicle WIM installation. Based on expert analysis, OWM 

understands that minimum requirements for apron smoothness, slope, etc. are needed in order to achieve 

necessary levels of accuracy. Both ASTM E-1318-09 and OIML R 134 include requirements that address 

the area leading to and from the sensor(s) of a WIM system. For example, the ASTM standard includes 

requirements for horizontal and longitudinal alignment, cross slope, surface smoothness, etc. 

3. NIST, OWM suggests that the WIM WG revisit the idea of including in the draft code additional accuracy 

classes for WIM’s capable of achieving greater accuracy levels. During the most recent WIM WG 
S&T Committee 2013 Final Report

S&T - 25

meeting, some manufacturers of WIM equipment indicated that their equipment could meet a 6 % gross 

vehicle weight tolerance, which is significantly less than the 10 % currently specified in the draft code. 

The WG then considered whether to include different accuracy classes and specify corresponding 

tolerances for those accuracy classes in the draft code. However, the WG ultimately agreed to a single 

accuracy class and set of tolerances for the following reasons:

• The WG felt it was more expedient to simply specify a single accuracy class and set the limit of 

accuracy for that classification at the lowest end of what it considered an acceptable level of 

accuracy given the application of the device, and

• The WG agreed that the tasks performed by a WIM system, whether that WIM system is a “virtual 

weigh station” or one installed in a ramp at a more permanent site (e.g., a “weigh station” along an 

interstate highway) is the same. 

NIST, OWM noted that tiered accuracy classes are already established in both ASTM E 1318-09 and 

OIML R 134. History has proven that it is better to establish a framework of tolerances around the various 

performance capabilities of equipment available in the marketplace early on in the development of the 

code, rather than designing the code around systems that provide lowest accuracy and then trying to change 

the code later. 

In early discussions with representatives from FHWA, it was stated that one of the FHWA’s main goals for 

developing the draft code was to improve the accuracy and reliability of WIM systems in order to reduce 

the number of compliant commercial vehicles (i.e., those within legal load limits), being directed to static 

scales, which slows the transportation of freight. O WM recognizes the additional work that would be 

required by the WIM WG if it were to decide to include additional accuracy classes, but by doing so, it 

would benefit many (e.g., transportation industry, consumers, etc.,) and improve the chances of the FHWA 

achieving one of its primary goals.

Mr. Dan Middleton, (Texas A&M University) WIM Project Task Manager, speaking on behalf of the U.S. FHWA, 

voiced support for the item by stating that the new code would improve consistency and legal credibility in the 

courts. He indicated that the United States does not have enough resources to adequately enforce highway weight 

requirements. Use and recognition of WIM standards in NIST Handbook 44 will allow better use of enforcement 

resources. In providing further evidence of the need for the code, he noted that currently less than one percent of 

vehicles directed to a static scale after being sorted on a WIM System are noncompliant. 

Mr. Steve Langford (Cardinal Scale Manufacturing Company) commented that Cardinal Scale Manufacturing 

Company manufactures a series of WIM scales and encouraged further development of the draft code. He indicated 

that tiered accuracy classes are not important, nor needed in the code, at this time. The purpose of the WIM is to 

identify vehicles for enforcement; this is contrary to the application of OIML R 134, which is intended for WIM 

systems used in trade. ASTM 1318 provides different accuracy classes, but only one of which corresponds with the 

application of the draft code.

Mr. Tim Chesser (Arkansas) recommended a statement be included in the Application Section of the draft code 

clarifying that the code is intended for screening/sorting purposes only. NIST Technical Advisor’s note: It is 

believed that paragraph A.1. of the draft code already addresses Mr. Chesser’s concern. Paragraph A.1. General. 

specifies that the code applies to systems used to weigh vehicles, while in motion, for the purpose of screening or 

sorting the vehicles based on vehicle weight to determine if a static weighment is necessary. 

Ms. Julie Quinn (Minnesota) supported maintaining the “Information” status of the item and encouraged the WG to 

move quickly to finalize completion of the draft code. 

Mr. Flocken expressed his appreciation for the comments received and indicated that he would forward them, along 

with OWM’s feedback, to the WG for consideration.

There were two positions posted on the NCWM 2013 Online Position Forum; both of which supported the proposal. 
S&T Committee 2013 Final Report

S&T - 26

It is the Committee’s understanding that Mr. Flocken will share OWM’s suggestions with members of the WIM WG 

prior to their next meeting and the WG will consider whether or not additional revisions to the draft code are 

necessary prior to proposing the code to the NCWM for adoption. 

321 BELT-CONVEYOR SCALE SYSTEMS

321-1 VC UR.1.2. Conveyor Installation 

(This item was adopted.)

Source: 

USNWG Belt-Conveyor Scales (2013)

Purpose: 

Remove the current restrictions on minimum and maximum belt lengths.

Item Under Consideration: 

Delete subparagraph UR.1.2.(h) of UR.1.2. Conveyor Installation and re-letter subsequent subparagraphs as follows:

UR.1.2. Conveyor Installation.

(a) Installation - General. – A belt-conveyor scale shall be so installed that neither its performance nor 

operation will be adversely affected by any characteristic of the installation, including but not limited 

to, the foundation, supports, covers, or any other equipment.

(Amended 2002)

. 

. 

. 

(g) Tripper and Movable Pulleys. – There shall be no tripper or movable head pulleys in the conveyor.

(h) Conveyor Length. – The conveyor shall be no longer than 300 m (1000 ft) nor shorter than 12 m 

(40 ft) from head to tail pulley.

[Nonretroactive as of January 1, 1986] 

(ih) Conveyor Orientation. – The conveyor may be horizontal or inclined, but, if inclined, the angle shall 

be such that slippage of material along the belt does not occur.

(ji) Conveyor Stringers. – Conveyor stringers at the scale and for not less than 6 m (20 ft) before and 

beyond the scale shall be continuous or securely joined and of sufficient size and so supported as to 

eliminate relative deflection between the scale and adjacent idlers when under load. The conveyor 

stringers should be so designed that the deflection between any two adjacent idlers within the weigh 

area does not exceed 0.6 mm (0.025 in) under load.

. 

. 

. 

(nm) Belt Alignment. – The belt shall not extend beyond the edge of the outermost roller of any carry side 

(top) roller in any area of the conveyor nor touch the conveyor structure on the return (bottom) side of 

the conveyor.

(Amended 1998 and 2008)

(Amended 2002, and 2012, and 2013) 
S&T Committee 2013 Final Report

S&T - 27

Background/Discussion: 

Belt-conveyor scale manufacturers participating in the USNWG on BCS have reported increased demand for shorter 

conveyor systems in commercial applications. The minimum conveyor length specified in sub-paragraph 

UR.1.2. (h) and other requirements in the Belt-Conveyor Scales Systems Code that set minimum spacing 

requirements between components on a b elt-conveyor scale system will not currently permit shorter systems. 

During their February 2012 meeting, the USNWG on BCS concluded that the limit of 40 ft for a conveyor is 

unrealistic due to the spacing required between components and that this requirement is too prescriptive. I n 

addition, the USNWG agreed that limiting the conveyor length to 1000 ft would be self-regulating to some extent, in 

that calibration and testing that incorporates the use of whole/full revolutions of the belt would be excessively time 

consuming. The USNWG also agreed that the performance of the weighing device should be evaluated without 

regard to conveyor length and that, if there are designs of devices that support acceptable performance using 

conveyors outside the limits of this requirement, the requirement should be stricken. A s an initial step towards 

removing language in the Belt-Conveyor Scale Systems Code that is prohibitive of shorter belt conveyor system

weigh-belts, the USNWG recommends that subparagraph UR.1.2.(h) be deleted. The USNWG plans to continue to 

develop further proposals to amend additional requirements within the BCS Code to recognize shorter belt-conveyor 

scale systems.

The elimination of UR.1.2.(h) will further align U.S. standards with the international requirement OIML R 50

Continuous totalizing automatic weighing instruments (belt weighers) in that OIML R 50 does not contain minimum 

or maximum requirements relating to conveyor length.

During their fall 2012 meetings, all of the Regional Associations supported the proposal as written and 

recommended it be forwarded to the NCWM for vote. Mr. Bill Ripka (Thermo-Fisher Scientific), speaking on 

behalf of Thermo-Fisher Scientific and the USNWG on Belt-Conveyor Scales at the WWMA meeting, supported

the proposal to eliminate UR.1.2.(h). He stated that the minimum (40 ft) restricts placement of the scale and that 

such a restriction is not consistent with other codes in NIST Handbook 44. He indicated that the USNWG on BCS 

is working on a proposal to allow smaller feeders. He has found that excessive belt scale lengths are self-regulating 

due to the difficulty in testing them. Additionally, weights and measures jurisdictions are easily granting exceptions 

to the limits currently in NIST Handbook 44, so there is no need for these restrictions. 

2013 NCWM Interim Meeting Open Hearings: Mr. Ripka, speaking on behalf of Thermo-Fisher Scientific and as 

Chairman of the USNWG on BCS, reiterated the comments he provided during the fall 2012 W WMA Annual

Meeting. 

NIST OWM stated that calibration and testing of belt-conveyor scale systems with excessively long conveyors could 

be problematic primarily due to the time needed to complete full revolutions of the conveyor belt. Belt-conveyor 

scale systems using excessively short conveyor belts may also present challenges in designing those systems to 

account for difficulties including the location and placement of conveyor components and maintaining proper belt 

tension during operation. OWM does not believe that it is appropriate for NIST Handbook 44 Belt-Conveyor Scale 

Systems Code to include a requirement that prescribes limitations on the maximum and minimum length of 

conveyors associated with belt-conveyor scales if it can be demonstrated that conveyors of a length outside these 

limits are capable of complying with all applicable performance requirements. 

OWM does not anticipate any negative effect with the removal of requirement UR.1.2. (h) Conveyor Length as 

proposed and acknowledged the point that the elimination of this sub-paragraph serves to further harmonize NIST 

Handbook 44 Belt-Conveyor Scale Systems Code with OIML R 50. 

The Committee agreed with the justification provided by USNWG on BCS and the comments received during the 

Open Hearings in support of this item and agreed to recommend the item for a vote. 

2013 NCWM Annual Meeting Open Hearings: The Committee heard comments in support of the item from 

Mr. Ripka, speaking on behalf of the USNWG on BCS systems and Mr. Flocken, speaking on behalf of the SMA. 

Mr. Ripka commented that weights and measures officials should evaluate belt-conveyor scale system performance 

and not prescribe design criteria. O WM reiterated the comments it provided during the 2013 NCWM Interim 

Meeting.

321-2 VC Appendix D – Definitions: Belt Revolution, Belt Load, Integrator, Loading Point, 

and Master Weight Totalizer 

(This item was adopted.)

Source: 

U.S. National Work Group on Belt-Conveyor Scales (USNWG BCS) (2013)

Purpose: 

Provide clarity of meaning for the use of terms in the Belt-Conveyor Scales Code to avoid confusion or misuse. 

Item Under Consideration: 

Add three new definitions and amend two existing definitions in Appendix D – Definitions associated with the 

Belt-Conveyor Scale Systems Code as follows:

belt load. – The weight of the material carried by the conveyor belt, expressed in terms of weight units 

per unit of length (e.g., pounds per foot, kilograms per meter. Also called Belt Loading.[2.21]

belt revolution. – The amount of conveyor belt movement or travel that is equivalent to the total length of 

the conveyor belt. Also referred to as “belt circuit.”[2.21]

integrator. – A device used with a belt-conveyor scale that combines conveyor belt load (e.g., lb/ft) and 

belt travel (e.g., feet) to produce a total weight of material passing over the belt-conveyor scale. An 

integrator may be a separate, detached mechanism or may be a component within a totalizing device. 

(Also see “master weight totalizer.”)[2.21]

loading point. – The A location at which material to be conveyed is applied to the conveyor on a conveyor 

where the material is received by the belt. The location of a hopper, chute, or the discharge of a pre-feed 

device used to supply material to a conveyor.[2.21]

master weight totalizer. – An primary indicating element used with a belt-conveyor scale that incorporates 

the function of an integrator to indicate the totalized weight of material that was passed over the scale. The 

master weight totalizer is a primary indicating element of the belt-conveyor scale. (Also see 

“integrator.”)[2.21]

NIST Technical Advisor’s Note: During their February 2013 meeting, the USNWG BCS agreed to further modify 

the definition of “loading point” to better clarify the location of the loading point on a conveyor. The USNWG

forwarded the following proposed definition to the S&T Committee to replace that shown above in Item Under 

Consideration: 

loading point. – The A location at which material to be conveyed is applied to the conveyor on a conveyor 

where the material is received by the belt. The location of the discharge from a hopper, chute or the 

discharge of a pre-feed device used to supply material to a conveyor. [2.21] 

Background/Discussion: 

Certain terms and phrases are used in NIST Handbook 44 and in discussions related to belt-conveyor scale systems 

that have specific meanings within that context. The terms “belt revolution,” “belt load,” and “integrator” appear in 

various paragraphs throughout the Belt-Conveyor Scale Systems Code and yet, are not currently defined in NIST 

Handbook 44. The terms “master weight totalizer” and “loading point” are currently defined in Appendix D. 

“Master weight totalizer” is frequently used interchangeably with the term “integrator.” The proposed amendment 

to this definition is intended to distinguish between these two terms while recognizing the interrelated functions of: 
S&T Committee 2013 Final Report

S&T - 29

1) the integration of belt travel and belt loading and 2) the totalization and display of weight passing over the 

weighing device. The changes proposed to the definition of “loading point” are intended to improve understanding. 

During the fall 2012 Regional Weights and Measures Association Meetings, each of the regions supported the 

proposal and recommended it be forwarded to NCWM as a Voting Item. Based upon meeting reports received from 

the various regions, there were few comments made during the meetings regarding the item, with most regions 

acknowledging their support of the item based on its development and recommendation by the USNWG on BCS. 

Mr. Bill Ripka (Thermo Fischer Scientific) commented during the WWMA meeting that he supported the addition 

of the new definitions of “belt revolution,” “belt load,” and “integrator” and the proposed changes to “loading point” 

and “master weight totalizer.” Mr. Ripka said that he believed it made sense to have a d escription in NIST 

Handbook 44 of what these terms mean. 

2013 NCWM Interim Meeting Open Hearings: Mr. Ripka, speaking on behalf of the USNWG on BCS, commented 

that the USNWG had reviewed and agreed on the definitions of the terms in the proposal and believed they were 

necessary to include in NIST Handbook 44. The USNWG believes that these definitions will improve 

understanding of these terms and provide more consistent application of requirements in the NIST Handbook 44 

Belt-Conveyor Scale Systems Code where these terms are used. 

NIST OWM noted that the definition of “loading point” already existed in Appendix D of NIST Handbook 44 and 

should not be presented as a new definition, but instead, as an amended definition in the “Item Under

Consideration.” OWM provided the Committee an amended version of the definition appearing in Appendix D of 

NIST Handbook 44 for consideration, which is the same definition included in the original proposal, except that it 

includes revisions shown in bold face print by striking out information to be deleted and underlining information 

to be added to the current definition in NIST Handbook 44. 

OWM acknowledged the merits of this proposal, to include providing three new definitions for terms that are used 

specifically in association with belt-conveyor scale systems as well as the proposed amendments of the existing 

definitions for “master weight totalizer” and “loading point.” These definitions clarify the meaning of these terms 

and will assist in the interpretation of the NIST Handbook 44 Belt-Conveyor Scale Systems Code.

The Committee agreed with comments received during the Open Hearings in support of the proposed definitions. 

The Committee agreed that the proposed definition of ”loading point” should be presented as a modification to the 

existing definition in NIST Handbook 44 a nd modified the proposal accordingly as shown in the Item Under 

Consideration. 

Based on the support for these changes, the Committee agreed to designate this as a Voting Item. 

2013 NCWM Annual Meeting Open Hearings: The Committee replaced the definition of “loading point” that was 

originally submitted as part of the proposal, with the modified version proposed by the USNWG on BCS following 

their February 2013 meeting. The modified version is included above in Item Under Consideration as part of the 

NIST Technical Advisor’s note.

OWM reiterated the comments it made during the 2013 NCWM Interim Meeting and also commented that the 

changes to the definition of “loading point” proposed by the USNWG on BCS improve the definition of that term by 

better clarifying the location of each loading point on a BCS system. 

The Committee also heard comments in support of the item from Mr. Ripka, who indicated that the information 

provided by the definitions will be very helpful in understanding terms that are not a part of everyone’s vocabulary. 

Mr. Ripka also encouraged other groups to review definitions pertinent to their expertise and make 

recommendations for updates as appropriate.

There was one position posted on the NCWM 2013 Online Position Forum in support of the proposal. 

The Committee modified the definition of “loading point” as recommended by the USNWG on BCS and presented 

the item for a vote as shown in the Item Under Consideration above.

330 LIQUID MEASURING DEVICES

330-1 W S.1.6.4.2 (a) Product Identity and UR.3.2. Unit Price and Product Identity

(This item was withdrawn)

Source: 

Missouri Department of Agriculture (2013)

Purpose: 

Reduce the potential for mis-fueling consumer vehicles. 

Item Under Consideration: 

The Committee considered the following proposal to amend paragraphs S.1.6.4.2. and UR.3.2. However, as 

described in the “Background/Discussion” section, the Committee decided to Withdraw this item from its agenda.

S.1.6.4.2. Product Identity.

(a) A device shall be able to conspicuously display on each side the identity of the product being 

dispensed.

(b) A device designed to dispense more than one grade, brand, blend, or mixture of product also shall be 

able to display on each side the identity of the grade, brand, blend, or mixture being dispensed.

(c) The term “Gasoline”, “E15Gasoline”, “E85”, or “Flex-Fuel” shall be conspicuously displayed 

on the dispenser nozzle(s). This subsection applies only to spark-ignition engine fuel 

dispensers.

(Amended 20XX)

UR.3.2. Unit Price and Product Identity. 

(a) The following information shall be conspicuously displayed or posted on the face of a retail 

dispenser used in direct sale:

(1) except for dispensers used exclusively for fleet sales, other price contract sales, and truck 

refueling (e.g., truck stop dispensers used only to refuel trucks), all of the unit prices at which 

the product is offered for sale; and

(2) in the case of a computing type or money-operated type, the unit price at which the dispenser is 

set to compute.

Provided that the dispenser complies with S.1.6.4.1. Display of Unit Price, it is not necessary that all the unit 

prices for all grades, brands, blends, or mixtures be simultaneously displayed or posted.

(b) The following information shall be conspicuously displayed or posted on each side of a retail 

dispenser used in direct sale:

(1) the identity of the product in descriptive commercial terms; and

(2) the identity of the grade, brand, blend, or mixture that a multi-product dispenser is set to deliver.
S&T Committee 2013 Final Report

S&T - 31

(c) The term “Gasoline”, “E15Gasoline”, “E85”, or “Flex-Fuel” shall be conspicuously displayed 

on the dispenser nozzle(s). This subsection applies only to spark-ignition engine fuel 

dispensers.

(Amended 1972, 1983, 1987, 1989, 1992, and 1993, and 20XX) 

Background/Discussion:

The level of confusion for consumers fueling vehicles continues to grow with the introduction of new fuels in the 

marketplace. The proposed changes are intended to ensure proper delivery of the selected product and to reduce the 

potential of mis-fueling vehicles. Missouri and other states have received complaints from consumers who have 

fueled their vehicles with inappropriate products. At this time, practically all gasoline dispensers nationwide do not 

comply with paragraph UR.3.2. or S.1.6.4.2.(a) as they do not display the product identity (i.e., gasoline). 

2012 CWMA Interim Meeting: The CWMA proposed that the item be designated as an Informational Item. The 

CWMA did not support the proposed change to paragraph S.1.6.4.2., but did support the change to UR.3.2. The 

CWMA recommended review of the item by the NCWM FALS. 

2012 WWMA Annual Meeting: Mr. Mahesh Albuquerque (Colorado) opposed this item because it is burdensome 

and adequate labeling requirements already exist. He noted that consumers need to take ownership and read the 

labeling to avoid mis-fueling. Mr. Gordon Johnson (Gilbarco) opposed this item because it doesn’t effectively solve 

the problem. He believes this should not be a specification, but rather a user requirement because 90 % of his 

company’s dispensers are sold without hoses and nozzles. He questioned how this requirement would even be 

implemented. M r. Ron Hassmeyer (Alameda County, California) opposed the item and stated that labeling in 

S.1.6.4.2. Product Identity is adequate to require a product description. He also questioned how this item would 

apply to a multi-product dispenser. Mr. Hassmeyer believed this would be an undue burden to the device owner. 

Mr. Doug Deiman (Alaska) recommended this item be Withdrawn, noting that it is too much of a burden on gas 

pump owners. M s. Kristin Macey (California) opposed this item and recommended Withdrawal. The WWMA

recognized the lack of support for this proposal and agreed that the product identity section adequately addresses this 

issue. Additionally, the WWMA did not understand the submitter’s comment that practically all gasoline dispensers 

nationwide do not comply with paragraphs UR.3.2. or S.1.6.4.2.(a). The WWMA did not forward the item to 

NCWM.

2012 NEWMA Interim Meeting: Members questioned whether this item should be a w eights and measures 

responsibility. NEWMA believes that this item should be addressed by FALS.

2012 SWMA Annual Meeting: Mr. Matt Curran (Florida) provided comments on behalf of Mr. Ron Hayes 

(Missouri). Mr. Hayes noted that the intent of the proposal was not to increase labeling requirements, but to provide 

an additional point at which a consumer would be informed of the product identity. H e had more interest in 

establishing a user requirement than a specification. Mr. Curran noted that there are stations in Florida that dispense 

E85 where the attendant specifically asks the consumer whether or not the vehicle can accommodate the fuel. 

Mr. Steve Benjamin (North Carolina) questioned how the requirement would be applied on a dispenser with a single 

hose used to dispense multiple products. He noted that the proposal seems to be just another variation on the 

proposed color-coding requirement considered in the past. Mr. Ed Coleman (Tennessee) supported the proposal, 

pointing out that more labeling on the dispenser may result in having too much information on the dispenser that no 

one reads. However, on nozzles, he believes that the labeling would have more visibility. Mr. Johnson opposed the 

item. Mr. Tim Chesser (Arkansas) opposed the item, noting concern about the impact of requiring new labeling on 

all existing nozzles. Mr. Bill Studzinski (General Motors) expressed appreciation for the effort to further clarify 

product identity, but opposed the proposal, noting that there is already a requirement for marking product identity in 

NIST Handbook 44. He echoed concerns about how the requirement would apply to single hose dispensers with 

multiple products. The majority of comments received by the SWMA were in opposition to the proposal. The 

SWMA appreciated the desire to improve consumer understanding but believed the proposal would not fully address 

mis-fueling incidents. Noting that there were too many questions about how the language would be applied, 

particularly with single-hose, multi product dispensers, SWMA did not forward the item to NCWM.

2013 NCWM Interim Meeting: Mr. John Albert (Missouri) gave a p resentation which illustrated the types of 

complaints that Missouri routinely receives. He indicated that this problem has been in existence for a long time, 
S&T Committee 2013 Final Report

S&T - 32

noting that customers associate the color “green” with diesel dispensers and frequently mistake dispensers with 

green gasoline nozzles for diesel dispensers. Mr. Albert reported that they have received thousands of complaints on 

this subject and they find that customers frequently make fueling mistakes because their attention is distracted by 

things such as discount information, station traffic, and other signage on the dispenser, not to mention personal 

distractions. He noted that octane stickers are not sufficient by themselves to alert distracted customers that the 

dispenser is dispensing gasoline and not diesel. Mr. Tim Columbus (Steptoe and Johnson), speaking on behalf of 

the National Association of Convenience Store Operators, expressed concern about the proposal, noting that this 

affects only a small percentage of customers and many of the customers who mis-fuel their vehicles admit they are 

not paying attention. He also commented that octane stickers on gasoline dispensers are adequate to alert consumers 

that the product is gasoline. Mr. Johnson reiterated comments made at the 2012 WWMA Annual Meeting, noting 

that about 95 % of Gilbarco’s customers do not purchase hoses and nozzles with new dispensers, preferring to put 

their own on the equipment upon installation. G ilbarco believes that, if the Committee decides to move forward 

with the proposal, it should be addressed through the addition of a user requirement. 

Mr. Hayes, speaking as Chairman of FALS, noted that FALS provided the Committee with alternative language. 

The alternative proposal eliminates the proposed addition of S.1.6.4.2.(c) and replaces the proposed UR.3.2.(c) with 

the following:

(c) The term “Gasoline”, “E15”, “E15 & Gasoline” for multiple product dispenser with single nozzle, 

“E85”, or “Flex-Fuel” shall be conspicuously displayed on the dispenser nozzle(s). This subsection 

applies only to spark-ignition engine fuel dispensers. This section satisfies subsection UR.3.2.(b)(1) 

requirement.

During its work session, the Committee clarified with Mr. Albert that Missouri believes that the current language in 

UR.3.2.(b)(1) provides means to require clear identification of the product identity; however, the proposed changes 

would promote uniformity in the use of terminology, not only for diesel dispensers, but also other fuels and, 

hopefully, reduce incidents of mis-fueling. Mr. Albert noted that Missouri is not able to enforce the use of specific 

colors to identify products without changes to NIST Handbooks 44 and 130.

After reviewing the original and alternate proposals and considering the comments received during the Open 

Hearings, the Committee expressed concerns about the extent of support for the proposal. T he Committee is 

concerned about the potential burden on stations to modify current equipment, particularly when there are questions 

about whether or not the proposed changes would significantly reduce mis-fueling incidents. Provided a dispenser is 

clearly labeled with the product identity as required by UR.3.2., the Committee believes that the customer must 

accept some responsibility to follow instructions and signage during the transaction. W hile the Committee 

appreciates the concerns that have been raised by Missouri, the Committee agreed that the proposed marking 

requirements would not resolve all mis-fueling problems and the Committee does not believe there is a consensus to 

support the proposal. Consequently, the Committee decided to Withdraw the item. 

At their spring 2013 Annual Meetings, NEWMA and the CWMA concurred with the Withdrawal of this item. The 

Committee received no further comments on the item during its 2013 Annual Meeting Open Hearings.

(Added 2002) (Amended 2006 and 2013) 

Background/Discussion:

This item was initiated as a r esult of discussions at an NTEP measuring labs meeting and forwarded to the 

Measuring Sector for review in 2011. I n reviewing criteria for heated products during discussions at the 2011 

annual NTEP Laboratory Meeting, the Measuring Laboratories noted inconsistencies in the way that heated products 

are referenced in the LMD, VTM, and MFM Codes.

The differentiation between “heated” and “non-heated” products first appeared in NIST Handbook 44 in 2000 as a 

result of a proposal adopted by the NCWM in 1999 to expand the tolerances applicable to meters use to measure 

asphalt above 50 °C (see S&T Committee Items 330-6 and 337-4 in the 1999 NCWM S&T Committee Final Report 

for details). T his reference was refined by the Committee in 2001 when changes were adopted to clarify the 

application of tolerances to asphalt at 50 °C in the LMD and MFM Codes. When the LMD and VTM Codes were 

modified in 2003 a nd 2004 to adopt an accuracy class table to mirror the Mass Flow Meter (MFM) Code, 

inconsistencies first appeared in the way that heated products were referenced among the codes.
S&T Committee 2013 Final Report

S&T - 34

This proposal and similar proposals elsewhere in the Committee’s agenda, suggest changes to correct these 

inconsistencies. A summary of the proposals is listed below.

Section: 3.30. Liquid-Measuring Devices; Table T.2. (S&T Item 330-2)

Section: 3.31. Vehicle-Tank Meters; Table 1. (S&T Item 331-1)

Section: 3.37. Mass Flow Meters; Table T.2. (S&T Item 337-3)

NIST OWM notes that there also may be a need to address hot water meters (for which the American Water Works 

Association (AWWA) defines a boundary temperature of 90 °F) in NIST Handbook 44.

The proposed changes in these items take into account corresponding references to heated products in NCWM 

Publication 14, including the “Product Families Table” in Technical Policy C and past discussions at meetings of the 

NTEP Measuring Sector. R evisions are also proposed to ensure appropriate references to both Fahrenheit and 

Celsius temperatures.

NEWMA and SWMA supported moving this item forward as a Voting Item at their 2012 Annual Meetings. The 

SWMA also recommended that this item be consolidated with correlating items in the VTM and MFM during the 

voting process to help ensure consistency among these codes.

2013 NCWM Interim Meeting: The Committee received comments in writing from NIST OWM reiterating the 

origin of the proposal and noting that the goal of the proposed changes is to improve consistency in references to 

heated products among the codes. OWM noted that this item is largely housekeeping and is intended (along with 

S&T Agenda Items 331-1 and 337-3) to clarify the application of tolerances to different types of heated products 

and to ensure consistency across several metering codes. T he MFM Code does not include any specified 

temperature threshold that would define “heated products” as is provided in both the LMD and VTM Codes. Since 

MFMs could be used in the same applications as other meter types covered by the LMD and VTM Codes, it would

be logical for the temperature threshold to be the same. Additionally, the current formatting of references to 

temperature thresholds is inconsistent among LMD, VTM, and MFM Codes. The Committee also heard comments 

from Mr. Michael Keilty (Endress and Hauser) who agreed with NIST OWM’s comments and further suggested that 

discussion be taken simultaneously on this item and Items 331-1 and 337-3 for expediency. Hearing no opposition 

to the proposed changes, the Committee agreed to move this item forward for a vote.

2013 spring NEWMA and CWMA Annual Meetings: NEWMA and the CWMA supported the designation of this 

item as a Voting Item and agreed with the need to resolve current inconsistencies. T hree government 

representatives indicated support for this item on the NCWM Online Position Forum with no additional comments.

2013 NCWM Annual Meeting: The Committee took comments on this item simultaneously with Items 331-1 and 

337-3. The Committee heard no comments in opposition to these items. Mr. Dmitri Karimov (Liquid Controls 

Corporation, LLC) stated that this is a good housekeeping item, and he supported considering this item in 

conjunction with related items in the VTM Code and the MFMs Code. NIST OWM reiterated its comments from 

the 2013 I nterim Meeting and suggested voting on Items 330-2, 331-1, and 337-3 together to avoid any 

inconsistencies.

330-3 I N.4.2.4. Wholesale Devices 

(The status of this item was changed from Voting to Informational.) 

Source: 

Flint Hills Resources (2013)

Purpose: 

To better align wholesale meter testing with current testing procedures, measuring practices and technology changes 

while maintaining the integrity of the special test.
S&T Committee 2013 Final Report

S&T - 35

Item Under Consideration: 

Amend paragraph N.4.2.4. as follows:

N.4.2.4. Wholesale Devices. – “Special” tests shall be made to develop the operating characteristics of a 

measuring system and any special associated or attached elements and accessories.

N.4.2.4.1. Special Test, Type Evaluation. – “Special” tests shall be made during type 

evaluation include a test at the slower of the following rates:

(a) 20 % of the marked maximum discharge rate; or

(b) The minimum discharge rate marked on the device. 

Add a new paragraph N.4.2.4.2. as follows:

N.4.2.4.2. Special Test, Field Evaluation. – “Special” tests shall be made during field tests at or near 

the minimum discharge flow rate developed under the conditions of installation, but not less than the 

minimum discharge rate marked on the device. 

Background/Discussion: 

This proposal is intended to clarify that conducting a slow flow test to the marked minimum discharge rate is 

required for type evaluation and testing to the minimum discharge flow rate developed under the conditions of 

installation for routine field inspections is appropriate. It would:

1. Remove the rigidity of the current language and provide for flexibility and efficiency while maintaining the 

requirement to test at different flow rates to determine the accuracy of a measuring system;

2. Differentiate between testing for type evaluation and field verification;

3. Reflect changes in field testing procedures, technology, and industry practices; and

4. Improve meter performance by establishing a meter factor for the slowest preset flow rate. 

The current language is very rigid and does not take field installation conditions into consideration. It may not be 

possible or practicable to achieve the marked minimum discharge rate during field tests without changes to upstream 

equipment (valves, pumps, etc.), changing the flow computer programmed presets, or changing the idling of other 

fueling bays during testing. 

The code does not allow for any deviation from the “shall” test at the marked minimum discharge rate. Current 

loading rack systems generally do not have a discharge nozzle or other physical means downstream of the meter to 

control or restrict the flow rate. Today, most rely on pumps and valves upstream of the meter and preprogrammed 

flow rates for specific products with an assigned meter factor for each flow rate and product. The proposed change 

would still allow for testing at the marked minimum discharge rate when there is a d ischarge nozzle or other 

physical means in use downstream of the meter to restrict flow, but would recognize the need to vary from the 

marked minimum discharge rate for systems not so equipped. 

The submitter notes that it is more productive to verify that the system is operating properly when used in its 

intended manner and set-up rather than alter the system for test-purposes and then return it to its “as-used 

condition.” Adjusting the system to flow at the marked minimum discharge rate by making changes to the system 

when that flow rate is not used introduces variables into the system not normally seen and adds little to no value. 

Even if the system can achieve the marked minimum discharge rate (for example, through the use of a discharge 

nozzle), it is not always practical or possible to hit it exactly when testing. T he variables involved with proving 

while multiple bays are operating at a loading rack can make achieving the target flow rate difficult. It is not really 

necessary to test exactly at the marked minimum flow rate to develop the operating characteristics of a meter. 
S&T Committee 2013 Final Report

S&T - 36

However, NIST Handbook 44 offers no room for deviation. Today, a wholesale meter tested “near,” but not exactly 

“at,” the marked minimum discharge rate is not being tested in accordance with the requirements of NIST 

Handbook 44. This problem may never be an issue, but it might (the history regarding the change to NIST 

Handbook 44, Introduction section illustrates why the language in the handbook must match the application of it in 

the field). Amending the current language as proposed will remove this risk, however, slight.

In the LMD Code, retail motor-fuel devices with a marked minimum flow rate are tested “at or near the marked 

minimum flow rate,” but are not required to be tested at exactly the marked minimum. If this is acceptable for a

retail motor-fuel dispenser, then it should be acceptable for a wholesale meter. The proposal would make testing 

more uniform and consistent among different but similar device types.

The purpose of this proposal is not to do a way with a special test but to make the test more reasonable. T he 

proposal would allow the integrity of the test process to be maintained while providing both industry technicians and 

weights and measures officials the flexibility to test the meter in a manner that is more reflective of actual field 

testing and device use. It is designed to test meters not at the design flow rate but at the flow rate at which they are 

actually used. It does not preclude a weights and measures inspector from testing at the marked minimum flow rate; 

it just removes the mandate to conduct it at that flow rate

The submitter points out the following supporting arguments: 

• The marked minimum and maximum discharge rates are design parameters, not operational parameters.

• The Mass Flow Meters Code does not require testing at the marked minimum discharge rate. It requires, at 

a minimum, that one test be conducted at the minimum flow rate of the installation.

• The principle of testing as used and not to the design parameters is present in other codes and testing. It 

exists for scales since scales are not required to be tested to their design parameters; they are only tested as 

set up and used. A scale may be rated at a capacity range of 100 000 lb to 200 000 lb and a scale division 

of 20 lb or 50 lb, but it will only be tested based on its conditions of installation regardless of how it could 

be used.

• NIST Handbook 44 does not require that a measuring system be tested at the marked maximum discharge 

rate because it recognizes the measuring system may not be able to achieve the marked maximum 

discharge rate due to the conditions of installation. 

• There is no regulation requiring a meter to be able to discharge at its marked minimum discharge flow rate; 

the marked minimum discharge flow rate is a design parameter not a use requirement.

• Not all tests in the test notes section are required to be conducted in the field as is noted in NIST Handbook 

44, Introduction, Section S. Using the handbook, which states, “Since some sections are designed to be 

applied to tests performed under laboratory conditions, it would be impractical or unrealistic to apply them 

to field tests. Not all tests described in the “Notes” section of the handbook are required to be performed in 

the field as an official test.” Based on this section, it could be argued that a “special” test is not even 

required; however, the submitter believes that the special test has value and is not seeking to eliminate the 

test entirely.

The proposal doesn’t specify the exact flow rate, but requires a test at the minimum flow rate based on the system 

and the establishment of a meter factor at that flow rate. The added flexibility and establishment of a meter factor 

during the test is important for both industry technicians and weights and measures officials.

The proposed change is similar to the recommended tests described in API Manual of Petroleum Measurement 

Standards (MPMS), Chapter 6.2. Loading Rack Metering Systems – “When using electronic presets with multiple

flow rate configurations, the establishment of multiple meter factors may be required. This is particularly true when 

low flow start-up and shutdown sequences are employed to prevent system shock and static electricity generation 

(see API RP 2003).”
S&T Committee 2013 Final Report

S&T - 37

A potential argument in opposition to the proposal is that, even if the system is not being used at the marked 

minimum discharge rate at the time of test, it could be used later; thus, it is important to not only test as found, but as 

it could be used. While there is some merit to this argument, it is not consistently applied since many systems are 

tested as found, not as they could be used. There is also no incentive for a fuel terminal to not test their system as 

used. Further, the current practice is to set a calibration factor for all flow rates, so it is unlikely that the system 

would be changed after testing without additional testing and establishment of a calibration factor.

Based on comments received at its 2012 Interim Meeting, the CWMA amended the original proposal to reflect 

language that was applicable to field practices and current with technology. The language was also amended to 

maintain special tests as a requirement during type evaluation, but optional for other examinations. C WMA 

supported the item as amended and forwarded the item to NCWM; recommending it as a Voting Item. The proposal 

submitted by the CWMA is as follows:

N.4.2.4. Wholesale Devices. – “Special” tests shall be made during type evaluation to develop the operating 

characteristics of a measuring system and any special associated or attached elements and accessories. 

“Special” tests shall include a test at the slower of the following rates:

(a) 20 % of the marked maximum discharge rate; or

(b) The minimum discharge rate marked on the device. 

N.4.2.5. Wholesale Devices; Other Tests. – Other tests may be made during field tests at or near the 

minimum discharge flow rate developed under the conditions of installation for all wholesale devices. 

(a) For devices equipped with electronic preset flow rates, tests may be conducted at any electronic 

preset flow rate used, including the slowest flow rate, when multiple flow rate configurations are 

used to deliver product.

(b) “Normal” applicable tolerances shall apply to tests conducted.

U.R.3.6.4. Wholesale Devices; Electronic Preset Flow Rates – A meter factor shall be established for all 

electronic preset flow rates used to deliver product.

2013 NCWM Interim Meeting: The Committee heard comments from Mr. Ross Andersen (New York, retired) who 

suggested if the concern is that there is not enough flexibility in the reference to “20 % of the marked maximum,” 

the focus should be placed on modifying this reference rather than making other proposed changes. He provided 

alternative language for the Committee to consider. The Committee also received written and verbal comments 

from NIST, OWM noting that the proposed language would not consider any test conducted at lower flow rates to 

be ‘normal” tests and, therefore, such tests would be required to meet “normal” test tolerances. 

OWM commented that it is important to verify the performance of a meter over the range of flow rates for which it 

is designed to operate. The “normal” test (as described in N.4.1. Normal Tests) combined with a “slow flow” test 

(as described in N.4.2.4. Wholesale Devices) allows an inspector or serviceperson to verify the performance of a 

meter over the range in which it is typically used under the conditions of its installation. For positive displacement 

meters with single point calibration, the results of both tests can be used to determine whether or not a particular 

meter is providing accurate measurement over the complete range of operating speeds associated with its installation 

and whether the meter is in good operating condition. Product discharge rates are affected by installation particulars 

(e.g., the diameter of the piping, pump speed), and these can be changed after installation, thus, affecting meter 

performance. For these reasons, OWM recommends the slow-flow test remain a required part of an official test as 

was originally intended by the original submitter of this item. As a general rule, OWM recommends that test 

procedures considered part of an official examination of a commercial weighing or measuring device not be made 

elective because, as such, they create the potential for inconsistent enforcement of legal requirements amongst 

weights and measures jurisdictions.

The proposed new paragraph N.4.2.5. Wholesale Devices; Other Tests allows for a test at the minimum discharge 

rate marked on the device but would have the effect of eliminating the application of the “Special Test” tolerance, 

which currently applies to the results of a test conducted at flow rates below a certain point. Since the test would no 

longer be considered a “Special Test,” basic tolerances (i.e., 0.3 % maintenance and 0.2 % acceptance) would apply 

and these tolerances are more stringent than the current “Special Test” tolerance of 0.5 % specified in NIST 

Handbook 44. O WM is concerned about the impact this change may have on existing in-service wholesale 

equipment that might currently be able to comply with the “Special Test” tolerance, but may not be able to comply if 

that tolerance were tightened. For example, in instances where the minimum discharge flow rate developed under 

the conditions of installation (i.e., the test condition specified in proposed new paragraph N.4.2.5. Wholesale 

Devices; Other Tests) for a wholesale device already in service, is equivalent to the lesser of the two rates specified 

in N.4.2.4., the flow rate for the test, whether applying proposed paragraph N.4.2.5. or existing paragraph N.4.2.4., 

would be the same, yet a more stringent tolerance would apply under proposed paragraph N.4.2.5. 

An additional concern is that if the parameters of the test were changed from those currently specified in (a) and (b) 

of paragraph N.4.2.4. to the proposed “at or near the minimum discharge flow rate developed under the conditions 

of installation” the change would provide device owners the latitude of being able to try and extend the service life 

of a meter by compensating for badly worn or otherwise defective parts simply by increasing the minimum flow rate 

of product through it. Although such action would constitute a violation of G-UR.4.3. Use of Adjustments, it might 

be very difficult for officials to recognize and enforce. 

For these reasons, OWM proposed alternate language (which combines elements of the original proposal and the 

CWMA alternative) as a means to provide more flexibility in conducting special tests, while retaining the original 

intent of the special test as a tool for verifying the condition of the meter.

OWM also commented that additional work is needed to develop minimum testing requirements for equipment with 

multi-point calibration capability to ensure consistency in inspection and testing of these systems.

Mr. Henry Oppermann (Weights and Measures Consulting) echoed OWM’s concerns regarding the need to conduct 

special tests as a means to assess the condition of the meter. He acknowledged that the current language in NIST

Handbook 44 may not provide the same flexibility that is provided for other meter types (for which tests can be “at 

or near” the marked minimum); however, he expressed concern about backing off of a proper test for what appears 

to be primarily convenience. M r. Constantine Cotsoradis (Flint Hills Resources) pointed out with many current 

systems, there frequently is not a way to restrict the flow rate. Mr. Richard Suiter (Richard Suiter Consulting) 

further commented that the location where flow is restricted (e.g., before vs. after the meter) during special tests can 

also affect the results of testing, and this should be considered in constructing the final language (and associated test 

procedures) for any proposed change.

Mr. Dmitri Karimov (Liquid Controls Corporation, LLC), speaking on behalf of the MMA, noted that the proposal 

has the effect of 1) providing some flexibility in establishing a flow rate near the marked minimum flow rate rather 

than at the minimum; 2) changing the tolerances that would apply to tests conducted at slower flow rates; and 

3) specifying the establishment of meter factors for preset flow rates. Of these three facets, MMA only supports the 

first. He noted that some registers may use different types of calibration factors and addressing these variations in a 

single paragraph would be difficult. He further noted, if changes are made to the test conditions in the LMD Code, 

similar changes should be made to other measuring codes as needed to ensure consistency.

Ms. Julie Quinn (Minnesota) noted that Minnesota believes that it is necessary to conduct testing at every flow rate 

where the device is configured; however, the factors at these various points do not need to be different.

The Committee acknowledged the comments in support of maintaining the requirement for conducting special tests 

during routine field inspections, but modifying paragraph N.4.2.4. to provide for some flexibility in the rate at which 

a special test is conducted. In recognition of limitations which may prevent some systems from being tested exactly 

at the marked minimum flow rate, the Committee agreed that modification to the language to be more consistent 

with other measuring devices is appropriate. Based on the support heard for the language proposed by OWM with 

respect to N.4.2.4.1. Special Test, Type Evaluation and N.4.2.4.2. Special Tests, Field Evaluation, the Committee 

agreed to recommend this alternative language as shown in the Item Under Consideration above for a Vote.
S&T Committee 2013 Final Report

S&T - 39

In reviewing the remaining portion of the proposed changes, the Committee noted the considerable debate regarding 

the inclusion of the User Requirement regarding the establishment of meter factors for preset flow rates. Based on 

this opposition, the Committee considered splitting this proposal into two items: 1) to address the proposed changes 

to the Notes; and 2) to address the proposed changes to the User Requirements. However, there was very limited 

support for the proposed changes to the User Requirement. Thus, the Committee decided to eliminate the proposed 

paragraph U.R.3.6.4. Wholesale Devices; Electronic Preset Flow Rates from the Item Under Consideration.

2013 NEWMA and CWMA Annual Meetings: NEWMA and the CWMA supported the item as a Voting Item and 

commented that they believe the concerns stated by OWM and others at the NCWM Interim Meeting have been 

sufficiently addressed by the NCWM S&T Committee.

Two Government representatives indicated a position of support on the NCWM Online Position Forum. Another 

Government representative, Mr. Randy Jennings (Tennessee) indicated opposition to the proposal and, noting that 

the item appeared on only one regional weights and measures association agenda, expressed concern that the item 

requires more vetting. Mr. Jennings expressed concern about the phrase “developed under the conditions of the 

installation,” and noted that this may be interpreted to mean that, if a system can be installed to run at maximum 

flow rates other than “start-up” and “shut-down,” then an official cannot request that the system be “chocked” to 

reduce the flow. H e further commented that the reduced flow test has always been effective in detecting and 

diagnosing wear in the meter. He also noted that Tennessee has a valve on its prover that can be used to reduce the 

flow rate during a slow-flow test. M r. Jennings proposed the following alternative changes to paragraph 

N.4.2.4.1. Special Test, Type Evaluation that would make the current requirement less restrictive; yet achieve a 

compromise to help all stakeholders:

N.4.2.4.1. Special Test, Type Evaluation. – “Special” tests shall include a test at the slower of the following 

rates:

(a) Approximately 20 % of the marked maximum discharge rate; or

(b) The approximate minimum discharge rate marked on the device.

During its Open Hearings at the 2013 Annual Meeting, the Committee received a proposed modification to the Item 

Under Consideration by the original submitter Mr. Cotsoradis. In addition to the other changes proposed in the Item 

Under Consideration, Mr. Cotsoradis proposed replacing the new paragraph N.4.2.4.2. with the following:

N.4.2.4.2. Special Test, Field Evaluation. – A “Special” test shall be made during field tests at or near 

the minimum discharge flow rate developed under the conditions of installation, but not less than the 

minimum discharge rate marked on the device. Additional “Special” tests may be conducted at flow 

rates down to and including the maximum discharge rate marked on the device.

Mr. Jennings supported this proposed modification by Mr. Cotsoradis.

Mr. Cotsoradis further noted that the current language in NIST Handbook 44 is very restrictive. Even in systems 

where the flow can be reduced, it is difficult to set the flow and maintain it at the target flow rate over the course of 

an entire test.

OWM noted that, according to the 1949 NCWM S&T Committee Report, requirements to conduct “Special Tests” 

were established in 1949. The report states that “Special” tests are not defined in detail except that such tests shall 

include tests at specified minimum discharge rates; other details of “Special” tests are left to the judgment of the 

official. The primary purpose of the “Special” test is to determine the condition of the meter and determine whether 

or not the user is maintaining the equipment in proper operating condition. As noted in comments during the 

2013 Interim Meeting, the results of a “Special” test, conducted at a slow flow rate, when compared with the result 

of a “Normal” test can indicate the condition of the meter. In general, the greater the difference between meter 

errors observed for the “Normal” and “Special” test, the stronger the indication that the meter is in need of 

reconditioning. It is questionable whether or not two tests conducted at flow rates that are not appreciably different 

will provide adequate information about the condition of a meter. If the features of a particular installation do not

S&T - 40

permit testing at the slower rates as currently required in paragraph N.4.2.4.Wholesale Devices, paragraph 

G-UR.4.4. Assistance in Testing Operations may be applied to facilitate a proper test. OWM also pointed out that 

when this requirement was first added the dominant meter technology was positive displacement meters. Since that 

time a number of different technologies have been developed and it may be necessary to reassess what minimum 

testing is necessary. OWM also noted that in training provided by NIST on testing of these systems, OWM 

recommends running tests at slightly above the targeted flow rate; this helps to prevent the flow rate from dropping 

below the meter’s marked minimum flow rate and, thus, helps to ensure a fair test of the metering system. OWM 

also reiterated comments it made during the 2013 Interim Meeting concerning the need to develop testing 

requirements for equipment with multi-point calibration capability.

Mr. Andersen suggested that the specifics of what testing is required would best be addressed in the NIST EPOs. 

Mr. Karimov expressed concern about testing at flow rates which create pressures exceeding the rated pressure of 

the meter. The Committee heard additional comments from conference members expressing confusion over what 

minimum testing should be required.

Mr. Michael Keilty (Endress + Hauser), chairman of the NTEP Measuring Sector, recommended that the item be 

moved to an information status. He suggested asking the Sector to review this issue and provide suggestions to the 

Committee on how to best address special tests on wholesale devices. T his suggestion was supported by several 

other NCWM members.

The Committee agreed to ask the Measuring Sector to review and provide suggestions on this issue. Consequently, 

it changed the status of this item from “Voting” to “Informational” to allow for additional input from the Sector and 

other interested parties.

330-4 I UR.3.3. Computing Device. 

Source: 

NCWM Task Group on Retail Motor Fuel Dispenser Price Posting and Computing Capability (2013) 

Purpose: 

Refine the criteria in the LMD Code related to price posting and computing capability of RMFDs for post-delivery 

discounted transactions to more clearly reflect the recommendations of the NCWM Task Group on RMFD Price 

Posting and Computing Capability for the indication of the highest unit price. 

Item under Consideration: 

Amend paragraph UR.3.3.(c) as follows to: 1) add the underlined text; and 2) modify the alignment of the statement 

regarding electronic receipts following paragraph UR.3.3.(c)(2) such that it aligns with parts (a), (b), and (c): 

UR.3.3. Computing Device. – Any computing device used in an application where a p roduct or grade is 

offered for sale at one or more unit prices shall be used only for sales for which the device computes and 

displays the sales price for the selected transaction.

(Added 1989) (Amended 1992)

The following exceptions apply:

(a) Fleet sales and other price contract sales are exempt from this requirement.

(b) A truck stop dispenser used exclusively for refueling trucks is exempt from this requirement provided 

that:

(1) all purchases of fuel are accompanied by a printed receipt of the transaction containing the 

applicable price per gallon, the total gallons delivered, and the total price of the sale; and

(Added 1993)
S&T Committee 2013 Final Report

S&T - 41

(2) unless a dispenser complies with S.1.6.4.1. Display of Unit Price, the price posted on the dispenser 

and the price at which the dispenser is set to compute shall be the highest price for any transaction 

which may be conducted.

(Added 1993)

(c) A dispenser used in an application where a price per unit discount is offered following the delivery is

exempt from this requirement, provided the following conditions are satisfied:

(1) the unit price posted on the dispenser and the unit price at which the dispenser is set to 

compute prior to the application of any discount shall be the highest unit price for any 

transaction;

(2) all purchases of fuel are accompanied by a p rinted or electronic receipt upon purchaser 

demand recorded by the system for the transaction containing:

a. the product identity by name, symbol, abbreviation, or code number;

b. transaction information as shown on the dispenser at the end of the delivery and prior to any 

post-delivery discount including the:

1. total volume of the delivery; 

2. unit price; and 

3. total computed price of the fuel sale prior to post-delivery discounts being applied.

c. an itemization of the post-delivery discounts to the unit price; and 

d. the final total price of the fuel sale.

For systems equipped with the capability to issue an electronic receipt, the customer may be given the 

option to receive the receipt electronically (e.g., via cell phone, computer, etc.)

(Added 2012)

(Added 1998) (Amended 1992, 1993, and 2012)

Background/Discussion: 

2013 NCWM Interim Meeting: The NCWM Task Group (TG) on RMFD Price Posting and Computing Capability 

met to review examples of receipts and scenarios for compliance with language adopted into NIST Handbook 44 in 

2012 to address systems that are used to offer post-delivery discount pricing in retail motor-fuel dispensing 

applications. During that review, the TG noted that the language in paragraph UR.3.3.(c)(1) could be incorrectly 

interpreted to prohibit the application of both pre- and post-delivery discounts in a single transaction; the TG

develop proposed changes to the paragraph to address this concern. The current language in (c)(1) states that, in 

order to qualify for the exemptions offered for post-delivery discounts, the unit price posted on the dispenser and the 

unit price at which the dispenser is set to compute shall be the highest unit price for any transaction. In instances 

where a customer elects to receive a discount prior to the delivery (i.e., a “pre-delivery” discount), this might create 

an unintended conflict. For example, if a customer elects to pay in cash at the start of the transaction, the dispenser 

might display and compute at a lower, cash unit price. Since UR.3.3.(c)(1) stipulates posting and computing at the 

highest unit price, some might interpret this to mean that this dispenser may not also participate in post-delivery 

discount pricing or be entitled to the exemptions in U.R.3.3.(c). The original intent of the changes proposed by the 

TG and adopted by the NCWM was not to restrict systems from participating in both pre- and post-delivery 

discounting. Consequently, the TG proposes changes as outlined in UR.3.3.(c)(1) in the Item Under Consideration 

above.

The TG also developed proposed changes to UR.3.3.(c)(2) as shows in the Item Under Consideration to 

acknowledge that: 1) the system must be able to provide a receipt to the customer, but the customer can be given an 
S&T Committee 2013 Final Report

S&T - 42

option of receiving the receipt or not; and 2) an electronic receipt is an acceptable alternative to a hard copy receipt 

if the purchaser agrees to an electronic receipt in lieu of, or in addition to, a hard copy. The Task Group believes 

that, should a customer prefer not to receive a receipt or prefer to receive it electronically, this should be 

permissible.

Lastly, the TG recommended changing the vertical alignment of the statement following UR.3.3.(c)(2) regarding the 

option of an electronic receipt so that it c learly applies to UR.3.3.(a), (b), and (c) rather than just part (c). A s 

presently shown in NIST Handbook 44, this statement would apply only to UR.3.3.(c). The text shown in the Item 

Under Consideration above aligns that statement such that it would apply to UR.3.3.(a), (b), and (c).

The Committee agreed to add this item to its agenda to address these changes proposed by the TG. The Committee 

believes the proposed changes have merit and believe they simply clarify the original intent of the language 

developed by the TG and adopted by the NCWM. However, because the proposed changes were not available for 

publication and review in NCWM Publication 15, the Committee agreed that the item should be designated as an 

Informational item to allow adequate opportunity for the review and comment by all stakeholders potentially 

affected by the proposed changes. The Committee also believes this will provide an opportunity for input on the 

specific language to ensure that it clearly and adequately addresses the concerns identified by the TG. 

The Committee agreed to retain Item 360-3 as a Developing Item while the TG continues work to develop 

guidelines and examples on how the changes made to the LMD Code in 2012 will apply to receipts for post-delivery 

discounted transactions. See Item 360-3 for additional background information on this work. 

2013 NEWMA Annual Meeting: NEWMA recommended this item be designated as a “Voting” Item on the 

NCWM Agenda in the 2014 NCWM cycle. NEWMA believes that the proposed changes will help clarify the intent 

of the WG’s original suggestion.

2013 CWMA Annual Meeting: The CWMA recommended the item be designated as an “Information” Item.

Two government representatives supported the proposed changes and one government representative indicated a 

neutral position on the item in the 2013 NCWM Online Position Forum.

2013 Annual Meeting: The Committee heard comments from OWM suggesting that the proposed modifications to 

UR.3.3.(c)(2) are unnecessary given that the paragraph already includes the following statement permitting the use 

of electronic receipts.

For systems equipped with the capability to issue an electronic receipt, the customer may be given the 

option to receive the receipt electronically (e.g., via cell phone, computer, etc.). 

Similar provisions are included in paragraphs S.1.6.7. Recorded Representations and S.1.6.8. Recorded 

Representations for Transactions Where a Post-Delivery Discount(s) is Provided. NIST, OWM also noted that the 

proposed wording in UR.3.3.(c)(2) inadvertently requires that the system be capable of providing an electronic 

receipt upon customer demand, regardless of whether or not the system is capable of providing one. The Committee 

heard multiple comments in support of eliminating the proposed revisions to UR.3.3.(c)(2). The Committee also 

heard comments from multiple weights and measures jurisdictions expressing the need to retain the requirement for 

a hard copy receipt for those consumers who do not have access to an electronic version. Mr. Ross Andersen

(New York, retired) noted the need to consider any requirements at the state level that apply to electronic records.

Comments received during the Open Hearings indicated that, in applications where receipts are required, the 

following principles should apply:

• A printed receipt must be made available to the customer. 

• If a customer doesn’t want a receipt, it is not necessary to provide one. 

• The customer may be given the option of receiving an electronic receipt in lieu of a printed receipt. 
S&T Committee 2013 Final Report

S&T - 43

The Committee also heard comments from both weights and measures jurisdictions and industry representatives 

suggesting that a provision be added to the General Code recognizing the acceptance of electronic receipts. 

Mr. Matt Curran (Florida) commented that identifying and defining different types of discounts, such as “rebates,” 

would be helpful for consumers as well as officials in understanding how these requirements apply.

(Added 2002) (Amended 2013) 

Background/Discussion:

This item was initiated as a result of discussions at an NTEP measuring labs meeting and forwarded to the 

Measuring Sector for review in 2011. I n reviewing criteria for heated products during discussions at the 2011 

annual NTEP Laboratory Meeting, the Measuring Laboratories noted inconsistencies in the way that heated products 

are referenced in the LMD, VTM, and MFM Codes.

The differentiation between “heated” and “non-heated” products first appeared in NIST Handbook 44 in 2000 as a 

result of a proposal adopted by the NCWM in 1999 to expand the tolerances applicable to meters used to measure 

asphalt above 50 °C (see S&T Committee Items 330-6 and 337-4 in the 1999 NCWM S&T Committee Final Report 

for details). T his reference was refined by the Committee in 2001 when changes were adopted to clarify the 

application of tolerances to asphalt at 50 °C in the LMD and MFM Codes. When the LMD and VTM Codes were 

modified in 2003 and 2004 to adopt an accuracy class table to mirror the MFM Code, inconsistencies first appeared 

in the way that heated products were referenced among the codes.

This proposal and similar proposals elsewhere in the Committee’s agenda, suggest changes to correct these 

inconsistencies. A summary of the proposals is listed below.

Section: 3.30. Liquid-Measuring Devices; Table T.2. (S&T Item 330-2)

Section: 3.31. Vehicle-Tank Meters; Table 1. (S&T Item 331-1)

Section: 3.37. Mass Flow Meters; Table T.2. (S&T Item 337-3)

NIST OWM notes that there also may be a need to address hot water meters (for which the American Water Works 

Association (AWWA) defines a boundary temperature of 90 °F) in NIST Handbook 44.

The proposed changes in these items take into account corresponding references to heated products in NCWM 

Publication 14, including the “Product Families Table” in Technical Policy C and past discussions at meetings of the 

NTEP Measuring Sector. R evisions are also proposed to ensure appropriate references to both Fahrenheit and 

Celsius temperatures.

NEWMA and SWMA supported moving this item forward as a Voting Item at their 2012 Annual Meetings. The 

SWMA also recommended that this item be consolidated with correlating items in the VTM and MFM during the 

voting process to help ensure consistency among these codes.

2013 NCWM Interim Meeting: The Committee received comments in writing from NIST, OWM as outlined in 

Item 330-2 and heard a synopsis of these comments from Ms. Juana Williams (NIST, OWM) during the Open 

Hearings. The Committee heard comments from Mr. Michael Keilty (Endress + Hauser), who agreed with NIST, 

OWM’s comments and further suggested that discussion be taken simultaneously on this item and Items 330-2 and 

337-3 for expediency. Hearing no opposition to the proposed changes, the Committee agreed to move this item 

forward for a Vote.

(This item was adopted.)

Source: 

Northeastern Weights and Measures Association (2009 Developing Items Part 3.31., Vehicle-Tank Meters - Item 1.)

Purpose: 

Enable more consistent application of the tolerances between older and newer meters and address an unintentional 

gap that allows an unreasonably large tolerance for smaller meters.

Item Under Consideration: 

Amend paragraph T.4. and delete Table T.4 as show below. Note that this option was identified as “Option 2” in the 

Committee’s 2012 Final Report.

T.4.Product Depletion Test. – The difference between the test result for any normal test and the product 

depletion test shall not exceed tolerance shown in Table T.4. 0.5 % of the volume delivered in one minute

0.6 % of the volume delivered in one minute at the maximum flow rate marked on the meter for meters 

rated 380 Lpm (100 gpm) or lower. Test drafts shall be of the same size and run at approximately the same 

flow rate.

Background/Discussion: 

This item was submitted to NEWMA at its 2008 I nterim Meeting to propose an alternative to existing product 

depletion test tolerances which are based on the size of the meter. The Committee has agreed with the concept of 

basing the product depletion test tolerances on the marked maximum flow rate of the meter rather than on the 

marked meter size and considered several proposals for modifying the tolerances since this item was introduced in 

2008. Details of these proposals and associated discussion can be found in the Committee’s 2009-2012 final reports.

While recognizing that one goal of the original proposal was to reduce what the submitter considered an 

unreasonably large tolerance for smaller meters, the Committee expressed concern about the impact the proposal 

would have on these meters based on comments from Meter Manufacturers Association (MMA). F rom 

2009 to 2011, the Committee repeatedly requested data from industry and weights and measures officials to support

or oppose the proposals under consideration. In late 2011, nine county jurisdictions submitted field test data to the 

Committee for review.

2012 NCWM Interim Meeting: The Committee considered three options for modifying NIST Handbook 44. A 

summary of how the three options would apply is outlined in the following table. A second table illustrating 

examples of tolerances for common meter sizes and maximum flow rates is also included.

While acknowledging that the data was not obtained under controlled conditions or as part of a structured study, the 

Committee noted that the data was extremely valuable in assessing the relative impact of the three options proposed. 

The Committee agreed that Option 2 represented a reasonable compromise between the original proposal, Option 1, 

and the MMA’s proposal, Option 3. The Committee proposed this option as an Informational Item to allow time for 

any additional input with the intent of moving the item to Voting in 2013.

2012 fall regional NCWM Annual Meeting:  ̈The Committee heard comments from MMA supporting the proposal. 
S&T Committee 2013 Final Report

S&T - 47

2012 fall regional meetings: The weights and measures associations supported proposing Option 2 as a Voting Item

in 2013. A t the fall 2012 SWMA meeting, Mr. Michael Keilty (Endress + Hauser) reported on behalf of the 

Measuring Sector that the Sector thoroughly discussed this issue at its October 2012 meeting and agreed that Option 

2 should be proposed for a Vote.

2013 NCWM Interim Meeting Open Hearings: T he Committee heard comments from Mr. Ross Andersen 

(New York, retired) and Mr. Dmitri Karimov (Liquid Controls Corporation, LLC) supporting the proposed changes 

and encouraging the Committee to finalize the language. Hearing no opposition to the proposal, the Committee 

agreed to move it forward for a Vote.

2013 NEWMA and the CWMA Annual Meetings: Comments were heard indicating that the expression of the 

tolerance as it applies to a “volume delivered in one minute” may be confusing to some.

To address this concern, NEWMA proposed including a t able illustrating common examples of meter flow rates 

(similar to the table shown earlier in this item) be added to the NIST EPOs to assist field officials and industry in 

understanding the intended application of the requirements. The CWMA proposed the following changes to 

paragraph T.4. Product Depletion Test shown in Item Under Consideration: 

• T.4. Product Depletion Test. – The difference between the test result for any normal test and the product 

depletion test shall not exceed tolerance shown in Table T.4. 0.5 % of the volume delivered in one 

minute at the maximum flow rate marked on the meter for meters rated higher than 380 Lpm 

(100 gpm) or 0.6 % of the volume delivered in one minute at the maximum flow rate marked on the 

meter for meters rated 380 Lpm (100 gpm) or lower. Test drafts shall be of the same size and run at 

approximately the same flow rate.

Both NEWMA and the CWMA recommended the item be designated as a Voting Item. 

Two government representatives indicated support and two government representatives indicated a neutral position 

for this item on the NCWM Online Position Forum with no additional comments.

2013 NCWM Annual Meeting: T he Committee considered the additional revisions proposed by the CWMA to 

remove the reference to “the volume delivered in one minute.” OWM noted that this would result in a tolerance 

expressed in gallons per minute. T he phrase “the volume delivered in one minute” may seem a bit unwieldy; 

however, the flow rate marked on most meters is expressed in terms of a q uantity per time such as “liters per 

minute” or “gallons per minute.” I f the reference to the time period of “one minute” were deleted from the 

paragraph as suggested by the CWMA, the application of the tolerance would result in a “quantity per minute” 

rather than a finite “quantity in liters” or “quantity in gallons.” 

For example, if a meter were marked with a maximum flow rate of 100 gpm, the tolerance would be applied as 

follows:

0.6 % × 100 gal/min = 0.6 gal/min

In contrast, applying the tolerance to that same meter as specified in the Item Under Consideration would result in a 

tolerance expressed in gallons as illustrated below:

Amount delivered in one minute at the maximum flow rate marked on the meter =

 1 min × 100 gal/min = 100 gal

Tolerance = 0.6 % × 100 gal = 0.6 gal

Thus, OWM believes that it would be incorrect to remove the phrase “the volume delivered in one minute” from the 

paragraph. The suggestion provided by NEWMA may provide a more palatable alternative to help illustrate how 

the tolerance is applied and OWM could include such examples in both the NIST EPOs and training materials.
S&T Committee 2013 Final Report

S&T - 48

Consequently, the Committee agreed with the Item Under Consideration as originally proposed. The Committee 

concurred with NEWMA’s suggestion to include examples in the NIST EPOs and training materials.

336 WATER METERS

336-1 V UR.3. Installation Requirements 

(This item was returned to Committee.) 

Source: 

Neptune Technology Group Inc. (2013)

Purpose: 

Establish installation requirements in the Water Meters Code.

Item Under Consideration: 

Add a new paragraph UR.3. as follows:

UR.3. Installation Requirements.

UR.3.1. Manufacturer’s Instructions. – A water meter shall be installed in accordance with the 

manufacturer’s instructions. For utility type water meters, the installation shall be sufficiently 

secure and rigid to maintain this condition.

Background/Discussion:

There are no installation requirements for utility type meters in the Water Meters Code of NIST Handbook 44. The 

submitter proposed the following new paragraph be added to Section 3.36.:

UR.3. Installation Requirements.

UR.3.1. Manufacturer’s Instructions. – A utility type water meter shall be installed in accordance 

with the manufacturer’s instructions, and the installation shall be sufficiently secure and rigid to 

maintain this condition.

2012 WWMA Annual Meeting: Mr. Andre Noel (Neptune) indicated that Neptune, Badger, Sensus, Elster-AMCO, 

and Master Meter support this item. Mr. Ron Hassmeyer (Alameda County, California) supported the item, but 

voiced concerns related to installation such as meter visibility. Ms. Kristin Macey (California) advised that there 

may be possible conflicts with other code language coming from other organizations such as AWWA and the Public 

Utilities Commission (PUC). The WWMA found it reasonable that the manufacturer’s instructions would be the 

basis for such installations. This proposal is similar to language used in NIST Handbook 44, LMD Code paragraph 

UR.2.1.; MFM Code paragraph UR.2.1.; and Hydrogen Gas-Measuring Devices Code paragraph UR. 2.1. T he 

WWMA also noted that UR.2. Accessibility of Customer Indications already addresses the issues of visibility. 

WWMA forwarded the item to NCWM, recommending it as a Voting Item.

2013 NCWM Interim Meeting: The Committee heard comments in support of the proposal from Mr. Noel, who 

indicated that he also spoke on behalf of Badger, Sensus, Elster-AMCO, and Master Meter and noted that the 

proposed change would mirror similar paragraphs in other NIST Handbook 44 measuring device codes. 

Mr. Jim Byers (San Diego County, California) stated that he agreed with the proposed requirement, but notes that 

the General Code already addresses these requirements. He suggested that, if the language in the General Code is 

not sufficient, then that language should be reviewed and revised rather than including additional language in the 

specific code. M s. Kristin Macy (California) stated that California agrees with Mr. Byers and believes that the 

language in the General Code is sufficient. Ms. Juana Williams (NIST, OWM) also acknowledged the similarity 

with language in other codes.
S&T Committee 2013 Final Report

S&T - 49

While the Committee acknowledged comments regarding the redundancy of the proposed paragraph with current 

General Code requirements, the Committee believes the proposal has merit in helping to ensure proper installation 

of water meters. The Committee believes the requirement in the first sentence of the proposed paragraph regarding 

compliance with the manufacturer’s instructions should apply to all water meters, not just utility type meters. 

Consequently, the Committee modified the language to restrict only the second sentence to utility type water meters 

and agreed to propose the modified paragraph (as shown in the Item Under Consideration above) for a Vote.

2013 Annual Meetings: NEWMA and the CWMA recommended this item be designated as Voting. 

One government representative indicated support; one government representative indicated a neutral position; and 

one government representative indicated opposition for this item on the NCWM Online Position Forum. T he 

opposing comment was accompanied by a statement indicating that paragraph G-UR.2.1. is adequate to address this 

concern and that paragraph is also more complete and better articulates the requirements. 

2013 NCWM Annual Meeting Open Hearings, the Committee heard comments in opposition to this item from 

Mr. Michael Keilty (Endress & Hauser Flowtec AG, USA) and Ms. Macey suggesting that the adding of 

requirements to address installation would be redundant. Mr. Keilty expressed concern that the absence of specific 

requirements such as these in all specific device codes might cause confusion about how or if the General Code 

paragraph would apply in those cases. Ms. Macey also expressed opposition to distinguishing between non-utility 

type and utility type water meters. NIST, OWM commented that the proposed language is consistent with that 

appearing in other device codes in NIST Handbook 44 and intended for the same purpose. The Committee received 

letters of support from Badger Meter; Elster AMCO Water, LLC; Sensus; Master Meter, Inc.; and Neptune 

Technology Group. Mr. Dmitri Karimov (Liquid Controls Corporation), speaking on behalf of the companies who 

were unable to attend this meeting and the Meter Manufacturers Association, also expressed support for this item. 

337 MASS FLOW METERS

337-1 I Appendix D – Definitions: Diesel Liter and Diesel Gallon Equivalents (DLE, DGE) 

Source: 

Clean Vehicle Education Foundation (2013)

Purpose: 

Enable consumers to make cost and fuel economy comparisons between diesel fuel and natural gas.

Item Under Consideration: 

Add the following definitions to Appendix D – Definitions:

Diesel Liter Equivalent (DLE). - means 0.756 kg of natural gas.

Diesel Gallon Equivalent (DGE). - means 2.863 kg (6.312 lb) of natural gas. 

Background/Discussion:

The gasoline gallon equivalent (GGE) unit was defined by NIST/NCWM in 1994 (See Appendix A) to allow users 

of natural gas vehicles to readily compare costs and fuel economy of light-duty natural gas vehicles with equivalent 

gasoline powered vehicles. For the medium and heavy duty natural gas vehicles in widespread use today, there is a 

need to officially define a unit (already in widespread use) allowing a comparison of cost and fuel economy with 

diesel powered vehicles. Also natural gas is sold as a vehicle fuel as either Compressed Natural Gas (CNG) or 

Liqufied Natural Gas (LNG) and each method of sale is measured in mass. Therefore, the generic term, natural gas 

is proposed to be used in NIST Handbooks 44 and 130 with out the existing term "compressed." The mathematics 

justifying the specific quantity (mass) of natural gas in a DLE and DGE is included in Appendix A.

The official definition of a DLE and a DGE will likely provide justification for California, Wisconson, and any other 

state to permit retail sales of LNG for heavy-duty vehicles in these convenient units.
S&T Committee 2013 Final Report

S&T - 50

2012 Interim Meeting: CWMA supported putting definitions of diesel liter equivalent and diesel gallon equivalent 

for natural gas into NIST Handbook 44, provided that FALS confirms the conversion factor prior to voting. CWMA 

forwarded the item to NCWM, recommending it as a Voting Item.

2012 WWMA Annual Meeting: Ms. Williams, NIST Technical Advisor advised that there are corresponding L&R 

Items 232-1 & 237-1, and suggested that the S&T and L&R Committees need to work on these items in tandem. 

The Committee believed this item has merit. T he WWMA expressed concerns with the source of equivalency 

values derived, noting it would like validation as to whether the values accurately represent the actual value of 

various types of natural gas products. The WWMA realized there are different compositions and sources. For 

example, LNG has a higher methane composition. There may be a possibility of additional conversion factors based 

on BTUs from different sources. The WWMA S&T Committee acknowledged meeting with the WWMA L&R 

Committee regarding this item. The two committees differed in their recommendations, between Informational and 

Developmental Item Status on the NCWM agenda. WWMA forwarded the item to NCWM recommending it as a 

Developing Item.

2012 Interim Meeting: NEWMA agreed to forward the item to NCWM, recommending it as an Informational Item.

2012 SWMA Annual Meeting: Mr. Michael Keilty (Endress + Hauser) noted some confusion about the values 

designated in the proposal. He also commented that there appears to be confusion about what the dispenser will 

display, particularly for dispensers that will serve vehicle types that run on gasoline as well as vehicle types that 

could run on diesel. H e asked whether the units will display in both GLE/GGE and DLE/DGE and how the 

dispenser will display this information. He suggested that this item be designated as a Developing Item to allow 

additional time to address these concerns. The SWMA reported that it did not believe that the proposal had been 

adequately developed with regard to the application of the proposed definitions, including aspects such as vetting of 

these values within the industry relative to actual gas supplies; explanation of how this will be applied consistently; 

and provisions for ensuring clear and understandable value comparisons by consumers (particularly given variations 

in gas supplies); and how this will apply to dispensers that may be used to fuel vehicles conventionally fueled by 

gasoline or diesel. The SWMA questioned whether it might be more appropriate for the community to consider 

establishing mass as the method of sale for natural gas and providing educational information through mechanisms 

such as pump toppers that would enable the consumer to compare the fuel costs with gasoline- or diesel-powered 

vehicles. T his approach would eliminate concerns about designating equivalent values that may not accurately 

represent the product being sold through a specific dispenser. SWMA unanimously agreed to forward the item to 

NCWM, recommending it as a Developing Item with development assigned to the submitter.

2013 NCWM Interim Meeting: The Committee heard multiple comments in opposition to the proposal. Mr. Keilty 

opposed the proposal, noting that a truck running on LNG would be dedicated to that type of fuel; thus, there is no 

need to make comparisons with diesel fuel on an ongoing basis. He believes natural gas should be sold in units of 

mass. Ms. Williams reviewed the following points prepared by OWM and suggested that the Committee consider 

these points in its deliberations on the proposals for this Item and Item 337-2. A copy of these points was also 

provided to the S&T Committee and the L&R Committee in writing in advance of the Interim Meeting.

Collaborative Work Effort

Work in joint session with the NCWM L&R Committee on corresponding L&R Agenda Items 232-1 (a proposal to 

recognize the diesel volume equivalent MOS for vehicle fuel) and 237-1 (a proposal to define the diesel volume 

equivalent unit in relation to mass) which specify the allowable unit of measurement for advertising and sale of 

natural gas. This collaboration between Committees will ensure that the proposed volume equivalent unit for a 

delivery is properly indicated and calculated by a natural gas dispenser. 

Facilitate Marketplace-Value Comparisons

A dispenser might serve vehicles that are powered by diesel or gasoline fuel. Therefore, which volume equivalent 

unit (the DGE or GGE) is appropriate to avoid confusing the consumer? What is the most appropriate means to 

provide sufficient information to customers attempting to make a comparison of fuel offered by the DGE and GGE, 

whether at the same station or stations on adjacent street corners? Today’s value comparisons are made to 

petroleum products, but as other alternative fuels proliferate how easy will it be for consumers to make comparisons 
S&T Committee 2013 Final Report

S&T - 51

to other fuels such as electricity or hydrogen?

An alternative that would provide more flexibility for comparison with other fuels and which would potentially 

create less confusion than permitting multiple different “equivalent” values as “units” of measure is to require the 

sale of all natural gas in mass units (kg or lb) as suggested by the SWMA. With this approach, customers could still 

be provided with supplemental information through mechanisms such as pump toppers that provide information 

about estimated equivalent units of measurement for deliveries indicated in mass as well as information on web sites 

such as those that already provide information about fuel economy. This approach might also reduce complaints 

from some suppliers about the accuracy of equivalent values relative to their product.

Another point that has been raised by some in the community and should be considered by the Committee is whether 

or not “equivalent values” are as necessary as they might have been at one time to encourage consumer acceptance 

of natural gas as an alternative fuel. For example, the SWMA questioned whether, once a consumer has purchased a 

vehicle he or she has the need to make ongoing value comparisons or whether this information is more useful prior 

to purchasing a vehicle. Given the concerns about consumer confusion with a potential proliferation of “equivalent” 

values at the dispenser, perhaps requiring mass units on the dispenser (with supplemental information about 

equivalents) is a more appropriate approach.

Compliance of Existing Approved Equipment-Indications

As noted above, NIST OWM suggests the Committee consider SWMA’s recommendation for equipment to indicate 

in a mass unit of measurement. Currently, there are two LNG dispensers with NCWM NTEP Certificates of 

Conformance (CC). They are NCWM CC 02-075A2* (Chart Industries) and NCWM CC 04-073A1 (NorthStar, 

Inc.), which specify these dispensers display in mass. How will the proposal apply to this equipment that may not 

have the capability to display in units other than mass? 

Earlier S&T Committee Positions

Does the S&T Committee plan to revisit its 1999 recommendation where it requested data on LNG be submitted 

prior to the recognition of this product in a metering application? The Committee might also recall that the S&T 

Committee took a position in 2008 on a related proposal to recognize the “DGE” recommending that a consensus 

between stakeholders exist on any single energy value used as a conversion factor. NIST OWM notes that several 

CNG suppliers have raised concerns about the use of 5.660 lb of CNG for each GGE commenting that this value is 

too low for the fuel they are providing to customers. O WM asks are other Sectors, which rely on the accurate 

accounting of vehicle motor fuel sales, aware of and in agreement with the proposed mass to volume equivalent unit 

being proposed as a conversion factor value for natural gas (CNG and LNG)? 

The data for the heating values cited in Table B.4. “Heat Content for Various Fuels” in the Transportation Energy 

Data Book Edition 30 (June 2011) was not developed as part of an NCWM study, but represents an account of work 

by a government sponsored agency to characterize transportation activity and other factors that influence 

transportation energy use. The book includes a disclaimer which states “in any attempt to compile a comprehensive 

set of statistics on transportation activity, numerous instances of inadequacies and inaccuracies in the basic data are 

encountered;” points out that “an appendix is included to document the estimation procedures;” and notes that 

“neither ORNL nor DOE endorses the validity of these data.”

Ms. Kristin Macey (California) opposed the proposal and urged the Committee to stop the proliferation of 

“equivalent units.” She noted that mass units are perfectly good for routine transactions and echoed comments that 

comparisons with other fuels are only relevant when making a purchase decision. Ms. Carol Hockert (NIST, OWM) 

further suggested that, during its deliberations, the Committee should consider how the establishment of artificial 

units would affect metrological traceability. Mr. Karimov (Liquid Controls Corporation, LLC), speaking on behalf 

of MMA, agreed with Ms. Hockert, noting that extensive work is done by companies to establish and maintain 

metrological traceability and the establishment of what amounts to arbitrary values is counterproductive. 

Mr. Dan Peterson (Yokogawa Corporation of America) echoed all of the statements made in opposition to the 

proposal.
S&T Committee 2013 Final Report

S&T - 52

Mr. Curtis Williams (CP Williams Energy Consulting) stated that he has had concerns about the use of the GGE and 

GLE for some years and he is glad that some are questioning the need to reconsider the use of equivalent units. As a 

participant in the U.S. National Working Group on Hydrogen, he was grateful that the associated code for that 

alternative fuel established requirements for mass units. He suggested that the Committee also consider examining 

the potential use of mass units for other fuels and noted that the use of mass units also eliminates questions about 

temperature compensation.

Ms. Judy Cardin (Wisconsin) acknowledged the need for the L&R Committee and the S&T Committee to work 

together on this and related items. She cited two main tasks to be addressed as: 1) What is the right conversion 

value for the proposed units?; and 2) Should units for the sale of natural gas be in “equivalent” units or mass units?

The Committee heard no comments in support of the proposal during its Open Hearings.

During its work sessions at the Interim Meeting, the S&T Committee met with the L&R Committee to discuss this 

item and related items on the two Committees’ agendas; the corresponding items on the L&R Committee Agenda 

are Items 232-1 and 237-1. During the joint meeting, the L&R Committee advised the S&T Committee that it had 

decided to make the related item on their agenda “Informational” to allow additional time for the community to 

study the issue and hear from other stakeholders in the community. A proposal was made to ask the FALS to 

deliberate on an appropriate equivalent value for each of the proposed “units.” H owever, the two Committees 

recognized that before asking the FALS to expend resources on further definition, the questions and concerns raised

in the Open Hearings regarding the appropriateness of recognizing such units should first be addressed. The 

Committees agreed to recommend to the NCWM Chairman that a small task group be established to further study 

this issue. The Committees each agreed to develop a list of tasks that they would ask such a task group to take on 

and to recommend possible members of the group to ensure balanced representation of stakeholders.

After discussion with the L&R Committee, the S&T Committee reviewed and summarized key comments made 

during the Open Hearings for S&T Committee Agenda Items 337-1 and 337-2:

• Are equivalent units necessary to promote consumer acceptance of this fuel?

• Is there a s ignificant need for continued comparison to other fuels once you have purchased a v ehicle? 

Does this justify the proliferation of “equivalent” values?

• The intent is to add this for medium- and heavy-duty vehicles such as trucks that operate on LNG. Trucks 

that operate on LNG are generally dedicated fuel vehicles that run only on a single fuel.

• Is the dispenser the appropriate place to make comparisons with other fuels or is a better place to make 

those comparisons via mechanisms such as pump toppers, websites, etc.?

• Striking the word “compressed” (in the changes proposed in Item 337-2) expands the proposal to LNG.

• California’s approval of LNG meters indicating in mass units was correct.

• What will the impact be on existing approval of LNG dispensers currently indicating in mass?

• There is much opposition to the proliferation of “equivalent units” for various types of fuels.

• The current recognition of GGE and GLE units has led to complaints about equivalent values from both 

industry and regulatory officials.

• Mass units should be considered for natural gas and other fuels.

• Will the establishment of equivalent values provide traceability to SI units?
S&T Committee 2013 Final Report

S&T - 53

• The community expends significant resources to achieve good meter performance and establishing “fuzzy” 

equivalent values seems to undermine these efforts.

• The factor for any “equivalent unit” will represent only an “estimate” of an equivalent value.

• There is disagreement amongst the industry regarding the appropriate equivalent value in this proposal. 

The report containing the data that is referenced as the basis for the proposal includes a disclaimer from 

Oakridge National Laboratory and U.S. Department of Energy regarding its validity for other than general 

use in the transportation industry.

• The S&T Committee only heard comments in opposition to the proposal.

• Harmonization with OIML requirements should be considered in the method of sale and associated device 

requirements.

With respect to Items 337-1 and 337-2, the Committee agreed to work collaboratively with the L&R Committee and 

to develop a small work group to decide: 1) whether or not DLE and DGE should be considered an acceptable 

method of sale for natural gas; and 2) if so, what should the factor be to determine their equivalents to gasoline. The 

Committee agreed that the above list of key points and questions heard during its Open Hearings should be 

considered, along with other Open Hearing comments, by the chairs of both the L&R and S&T Committee in the 

development of a list of points to be addressed by the Task Group.

2013 Annual Meeting: NEWMA recommended this item be withdrawn and commented that item that does not 

belong in NIST Handbook 44. N EWMA believes the consumer would be better served with comparisons or 

equivalents being made available through other sources more readily utilized by consumers (e.g., consumer websites 

or perhaps on new vehicle window stickers). 

2013 Annual Meeting: CWMA recommended the item be withdrawn in consideration of comments made in 

opposition to the item during the 2013 Interim Meeting. 

On the NCWM Online Position Forum one government representative indicated support; one government 

representative indicated a neutral position; and one government representative indicated opposition for this item. 

The neutral position was accompanied by a co mment suggesting the establishment of a joint Task Group and 

encouraging a final recommendation that would clarify whether the proposed units are or are not permitted. The 

opposing position was accompanied by a comment indicating opposition to artificial units of measure.

Prior to the 2013 Annual Meeting, NCWM Chairman, Mr. Steve Benjamin, appointed the “NCWM Natural Gas 

Steering Committee,” which will be chaired by Mr. Mahesh Albuquerque (Colorado). The primary charge of the 

Committee is to educate the membership regarding: the technical issues surrounding this application; the rationale 

for the proposed changes; the anticipated impact of the proposed changes and issues related to their implementation. 

The Committee was asked to identify and address questions raised during the 2013 Interim Meeting as well as other 

venues in an effort to enable NCWM members to make informed decisions about proposals under consideration in 

this area.

Also prior to the 2013 Annual Meeting, the Committee received a proposal from Mr. Douglas Horne (Clean Vehicle 

Education Foundation) to modify the Item Under Consideration. Mr. Horne proposed separate definitions for CNG 

and LNG gallon equivalent values. The Committee suggested he work with the steering committee to further refine 

the proposal and suggest changes to the item as appropriate. Mr. Horne’s proposals will be posted on the NCWM 

website with other documents relative to the Committee’s final report. While submitted in an NCWM Form 15 

template, Mr. Horne’s proposal is not addressing a new issue, but rather providing comments on a current item 

(Item 337-1) on the Committee’s agenda.

During its 2013 Annual Meeting Open Hearings, the Committee heard an update from Steering Committee 

Chairman, Mr. Albuquerque. He reported that the Steering Committee met for the first time on Sunday, July 14 at 

the beginning of the Annual and gathered input from those in the audience. Comments indicated that consumers 
S&T Committee 2013 Final Report

S&T - 54

may find gallon equivalent information to be helpful, but the most equitable method for measuring and selling the 

product is based on mass measurement.

The S&T Committee heard overwhelming comments opposing the use of gallon equivalents and favoring the use of 

mass as the method of sale. The Committee also heard multiple comments indicating concern about the 

establishment of a value that would be an approximation of the actual equivalent for a given transaction. Mr. Horne 

reported that some states have already or are in the process of enacting defined “gasoline equivalent” values; some 

adopted earlier versions of the equivalent and some are considering new values as outlined in Mr. Horne’s most 

recent proposal.

Ms. Macey noted that the NCWM successfully adopted a method of sale for hydrogen fuel based on mass and 

suggested that the natural gas be held to the same standard. Mr. Keilty commented that sale of natural gas as a 

vehicle fuel has proliferated globally and those sales are based on mass units.

NIST, OWM acknowledged appreciation of the establishment of the Steering Committee to further study this issue. 

NIST, OWM encourages the S&T Committee, the Steering Committee, and the weights and measures community to 

consider the points raised by OWM during the 2013 Interim Meeting as well as the following in their deliberations 

of Items 337-1 and Item 337-2: 

In addition to discussing the proposals in Items 337-1 and 337-2, OWM requests that the Task Group 

specifically discuss and consider whether or not the continued use of the terms “GLE” and “GGE” are 

appropriate for commercial CNG metering applications. NIST, OWM makes this request based on many of the 

same points made by OWM at the 2013 Interim Meeting and also given that:

1. this market is well established and consumer confidence and acceptance of CNG and other alternative fuels 

is not contingent upon continued comparisons with gasoline;

2. there are other methods for comparing relative efficiency and costs with gasoline;

3. experience with feedback from the community indicates problems with the application and validity of these 

units with changing gas supplies;

4. the proposal in Items 337-1 and 337-2 proposes language which would address natural gas as a whole and 

it is, therefore, appropriate to raise the discussion of whether or not the continued use of non-traceable units 

is appropriate. Additionally, OWM suggests that a proposal to eliminate the use of the terms “GLE” and 

“GGE” in favor of indications in mass units be developed and considered by the NCWM to ensure 

commercial transactions for natural gas are based on NIST traceable units of measure; and

5. as the number of viable alternative fuel options increase, providing a relatively static comparison with only 

one alternative fuel will not serve the broad needs of consumers and will make it unlikely that the dispenser 

is the appropriate location to provide comparison information. 

The Committee also heard a comment from Mr. Karimov suggesting that volume units be permitted as a method of 

sale for LNG.

While many people expressed an understanding of the need for consumers to make comparisons with gasoline, 

comments indicate that such comparisons would typically be made prior to the purchase of a vehicle and possibly 

for a short time while becoming accustomed to the vehicle. The Committee heard comments indicating that weights 

and measures officials would be amenable to permitting the posting or displaying of supplemental information 

regarding gallon equivalent values.

S.1.3.1.1. Compressed Natural Gas Used as an Engine Fuel. – When compressed natural gas is 

dispensed as an engine fuel, the delivered quantity shall be indicated in: “gasoline liter equivalent (GLE) 

units” or “gasoline gallon equivalent (GGE) units” (see definitions). 

(a) "gasoline liter equivalent (GLE) units" or gasoline gallon equivalent (GGE) units",

(b) "diesel liter equivalent (DLE) units" or "diesel gallon equivalent (DGE) units" (see 

definitions).

(Added 1994)

S.5.2. Marking of Diesel and Gasoline Volume Equivalent Conversion Factor. – A device 

dispensing compressed natural gas shall have: either the statement “1 Gasoline Liter Equivalent (GLE) is 

Equal to 0.678 kg of Natural Gas” or “1 Gasoline Gallon Equivalent (GGE) is Equal to 5.660 lb of 

Natural Gas” permanently and conspicuously marked on the face of the dispenser according to the 

method of sale used.

(a) either the statement "1 Gasoline Liter Equivalent (GLE) is Equal to 0.678 kg of Natural Gas" 

or "1 Gasoline Gallon Equivalent (GGE) is Equal to 5.660 lb of Natural Gas",

(b) either the statement "1 Diesel Liter Equivalent (DLE) is Equal to 0.756 kg of Natural Gas" or 

"1 Diesel Gallon Equivalent (DGE) is Equal to 6.312 lb of Natural Gas" permanently and 

conspicuously marked on the face of the dispenser according to the method of sale used.

(Added 1994)

Background/Discussion:

The gasoline gallon equivalent (GGE) unit was defined by NIST/NCWM in 1994 (see Appendix A) to allow users 

of natural gas vehicles to readily compare costs and fuel economy of light-duty natural gas vehicles with equivalent 

gasoline powered vehicles. For the medium and heavy duty natural gas vehicles in widespread use today, there is a 

need to officially define a unit (already in widespread use) allowing a comparison of cost and fuel economy with 

diesel powered vehicles. Also natural gas is sold as a vehicle fuel as either Compressed Natural Gas (CNG) or 

Liqufied Natural Gas (LNG) and each method of sale in measure in mass. Therefore, the generic term “natural gas” 

is proposed to be used in NIST Handbooks 44 and 130 with out the existing term "compressed". The mathematics 

justifying the specific quantity (mass) of natural gas in a DLE and DGE is included in Appendix A.
S&T Committee 2013 Final Report

S&T - 56

The official definition of a DLE and a DGE will likely provide justification for California, Wisconsin, and any other 

state to permit retail sales of LNG for heavy-duty vehicles in these convenient units.

2012 CWMA Interim Meeting: The CWMA supported putting definitions of diesel liter equivalent and diesel 

gallon equivalent for natural gas into NIST Handbook 44, provided that FALS confirms the conversion factor prior 

to voting. CWMA forwarded the item to NCWM, recommending it as a Voting Item with this provision.

2012 NEWMA Interim Meeting: NEWMA recommended that this item be forwarded to the NCWM as an 

Informational Item and suggested it be assigned to the FALS.

2012 WWMA Annual Meeting: Ms. Williams (NIST Technical Advisor) advised that there is corresponding L&R 

Items 232-1 and 237-1 and S&T and L&R need to work on these items in tandem. The WWMA believed this item 

has merit. The WWMA has expressed concerns with the source of equivalency values derived and reported it would 

like validation as to whether the values accurately represent the actual value of various types of natural gas products. 

The WWMA realized there are different compositions and sources. For example, LNG has a higher methane 

composition. There may be a possibility of additional conversion factors based on BTUs from different sources. 

The WWMA S&T Committee met with the WWMA L&R Committee regarding this item, but differed on their 

recommendations regarding whether the status of the related items on their agendas should be Informational or 

Developmental. The WWMA forwarded this item to NCWM, recommending it as a Developing Item.

2012 SWMA Annual Meeting: Mr. Michael Keilty (Endress + Hauser) noted that there appears to be confusion 

about what the dispenser will display, particularly for dispensers that will serve vehicle types that run on gasoline as 

well as vehicle types that could run on diesel. H e asked whether the units will display in both GLE/GGE and 

DLE/DGE and how the dispenser will display this information. He suggested that this item be designated as a 

“Developing” item to allow additional time to address these concerns. The SWMA reported that it did not believe 

that the proposal had been adequately developed with regard to the application of the proposed code changes, 

including aspects such as vetting of the referenced values within the industry with relative to actual gas supplies; 

explanation of how these requirements will be applied consistently; and provisions for ensuring clear and 

understandable value comparisons by consumers (particularly given variations in gas supplies); and how this will 

apply to dispensers that may be used to fuel vehicles conventionally fueled by gasoline or diesel. The Committee 

questioned whether it might be more appropriate for the community to consider establishing mass as the method of 

sale for natural gas and providing educational information through mechanisms such as pump toppers that would 

enable the consumer to compare the fuel costs with gasoline or diesel powered vehicles. T his approach would 

eliminate concerns about designating equivalent values that may not accurately represent the product being sold 

through a specific dispenser. SWMA unanimously agreed to forward the item to NCWM, recommending it as a 

Developing Item with development assigned to the submitter.

2013 NCWM Interim Meeting: the Committee heard comments from Mr. Keilty who expressed concern about the 

adoption of the proposed equivalent value as a unit of measure. He noted that the intent of this item is not to allow 

the user to toggle between mass units and equivalent units at the push of a button. He also noted that, if the units are 

set as “DLE” or “DGE,” the customer cannot also view units in “GLE” or “GGE.” Mr. Karimov (Liquid Controls

Corporation, LLC), indicated opposition to the proposal to strike the work “compressed.” Ms. Williams referenced 

NIST, OWM’s comments made in association with Agenda Item 337-1 and suggested that the Committee consider 

those same comments in their deliberations of this item.

The Committee heard no comments in support of the proposal during its Open Hearings. See Item 337-1 for details 

regarding the S&T Committee’s collaborations with the NCWM L&R Committee on Items 337-1 and 337-2 on the 

S&T Committee’s agenda and Items 232-1 and 237-1 on the L&R Committee’s agenda.

2013 NEWMA Annual Meeting: It was recommended the item be Withdrawn and commented that item that does 

not belong in NIST Handbook 44. NEWMA believes the consumer would be better served with comparisons or 

equivalents being made available through other sources more readily utilized by consumers (e.g., consumer websites 

or perhaps on new vehicle window stickers).

2013 CWMA Annual Meeting: The CWMA recommended the item be withdrawn in consideration of comments 

made in opposition to the item during the 2013 Interim Meeting.

On the NCWM Online Position Forum, two government representatives indicated a neutral position and one 

government representative indicated opposition for this item. The neutral position was accompanied by a comment 

suggesting the establishment of a Joint Task Group and encouraging a f inal recommendation that would clarify 

whether the proposed units are or are not permitted. The opposing position was accompanied by a comment 

indicating opposition to artificial units of measure and noting that establishment of DGE and DLE values perpetuate 

the use of artificial units.

(Added 1994) (Amended 1999, and 2001 and 2013)

Background/Discussion:

This item was initiated as a r esult of discussions at an NTEP measuring labs meeting and forwarded to the 

Measuring Sector for review in 2011. I n reviewing criteria for heated products during discussions at the 2011 

annual NTEP Laboratory Meeting, the Measuring Laboratories noted inconsistencies in the way that heated products 

are referenced in the LMD, VTM, and MFM Codes.

The differentiation between “heated” and “non-heated” products first appeared in NIST Handbook 44 in 2000 as a 

result of a proposal adopted by the NCWM in 1999 to expand the tolerances applicable to meters used to measure 

asphalt above 50 °C (see S&T Committee Items 330-6 and 337-4 in the 1999 NCWM S&T Committee Final Report 

for details). T his reference was refined by the Committee in 2001 when changes were adopted to clarify the 

application of tolerances to asphalt at 50 °C in the LMD and MFM Codes. When the LMD and VTM Codes were 

modified in 2003 and 2004 to adopt an accuracy class table to mirror the MFM Code, inconsistencies first appeared 

in the way that heated products were referenced among the codes.

This proposal, and similar proposals elsewhere in the Committee’s agenda, suggests changes to correct these 

inconsistencies. A summary of the proposals is listed below.

NIST, OWM notes that there may also be a need to address hot water meters (for which the American Water Works 

Association (AWWA) defines a boundary temperature of 90 °F) in NIST Handbook 44.

The proposed changes in these items take into account corresponding references to heated products in NCWM 

Publication 14, including the “Product Families Table” in Technical Policy C and past discussions at meetings of the 

NTEP Measuring Sector. R evisions are also proposed to ensure appropriate references to both Fahrenheit and 

Celsius temperatures.

2012 NEWMA and SWMA Annual Meeting: The associations supported moving this item forward as a Voting 

Item. The SWMA also recommended that this item be consolidated with correlating items in the VTM and MFM 

during the voting process to help ensure consistency among these codes.

2013 NCWM Interim Meeting: The Committee received comments in writing from NIST, OWM as outlined in 

Item 330-2 and heard a synopsis of these comments from Ms. Juana Williams (NIST, OWM) during the Open 

Hearings. Hearing no opposition to the proposed changes, the Committee agreed to move this item forward for a 

Vote.

2013 NEWMA and the CWMA Annual Meetings: The associations supported the designation of this item as a 

Voting Item and agreed with the need to resolve current inconsistencies. T hree government representatives 

indicated support and one government representative indicated a neutral position for this item on the NCWM Online 

Position Forum with no additional comments.

2013 NCWM Annual Meeting: The Committee took comments on this item simultaneously with Items 330-2 and 

331-1. See Item 330-2 for additional details.

354 TAXIMETERS

Note: At the 2013 NCWM Interim Meeting, the Committee considered a proposal to amend Section 5.54. in 

NIST Handbook 44 to make it specifically apply to Global Positioning System (GPS) system applications used 

commercially to compute fares based upon distance and/or time measurements. There was no specific language 

proposed for consideration. That item (Item 354-1) has been combined with 2013 Agenda “Item 360-5, 

S.5. Provision for Security Seals” and “Item 360-6 Global Positioning Systems for Taximeters” to create a new,

356-1 VC Table S.2.5. Categories of Device and Methods of Sealing 

(This item was adopted.)

Source: 

NTEP Grain Analyzer Sector (2013)

Purpose: 

Clarify that the requirements of Category 3 apply whether accessed manually using the keyboard or accessed by 

remote means, and that these requirements apply to all the subcategories of Category 3. 

Item Under Consideration: 

Amend Table S.2.5. as follows: 

Table S.2.5. 

Categories of Device and Methods of Sealing

Categories of Device Methods of Sealing

Category 1: No remote configuration capability. Seal by physical seal or two event counters: one for 

calibration parameters (000 to 999) and one for 

configuration parameters (000 to 999). If equipped with 

event counters, the device must be capable of displaying, or 

printing through the device or through another on-site 

device, the contents of the counters.

Category 2: Remote configuration capability, but 

access is controlled by physical hardware.

A device shall clearly indicate that it is in the remote 

configuration mode and shall not be capable of 

operating in the measure mode while enabled for 

remote configuration.

The hardware enabling access for remote communication 

must be at the device and sealed using a physical seal or 

two event counters: one for calibration parameters 

(000 to 999) and one for configuration parameters 

(000 to 999). If equipped with event counters, the device 

must be capable of displaying, or printing through the 

device or through another on-site device, the contents of the 

counters.

Category 3: Remote configuration capability access 

may be unlimited or controlled through a software 

switch (e.g., password).

When accessed remotely for the purpose of modifying 

sealable parameters, the device shall clearly indicate 

that it is in the configuration mode and shall not be 

capable of operating in the measuring mode.

An event logger is required in the device; it must include an 

event counter (000 to 999), the parameter ID, the date and 

time of the change, and the new value of the parameter (for 

calibration changes consisting of multiple constants, the 

calibration version number may be used rather than the 

calibration constants). A printed copy of the information 

must be available through the device or through another onsite device. The event logger shall have a capacity to retain 

records equal to twenty-five (25) times the number of 

sealable parameters in the device, but not more than 

1000 records are required. (Note: Does not require 

1000 changes to be stored for each parameter.)

Table S.2.5. 

Categories of Device and Methods of Sealing

Categories of Device Methods of Sealing

Category 3a: No remote capability, but operator is 

able to make changes that affect the metrological 

integrity of the device (e.g., slope, bias, etc.) in 

normal operation.

*When accessed for the purpose of modifying 

sealable parameters, the device shall clearly indicate 

that it is in the configuration mode and shall not be 

capable of operating in the measuring mode.

Same as Category 3

Category 3b: No remote capability, but access to 

metrological parameters is controlled through a 

software switch (e.g., password).

*When accessed for the purpose of modifying 

sealable parameters, the device shall clearly indicate 

that it is in the configuration mode and shall not be 

capable of operating in the measuring mode.

Same as Category 3

[Nonretroactive as of January 1, 1999 and *January 1, 2014] 

Background/Discussion:

All of the grain moisture meters (GMMs) in Categories 3, 3a, and 3b of Table S.2.5. use an electronic method of 

sealing, and most of them also offer access to the configuration mode thorough a keyboard entered password. In this 

mode, sealable parameters can also be changed locally through the keyboard. Category 3 of Table S.2.5. currently 

includes the following requirement:

When accessed remotely for the purpose of modifying sealable parameters, the device shall clearly indicate that 

it is in the configuration mode and shall not be capable of operating in the measuring mode.

At its 2011 Grain Analyzer Sector Meeting the Sector agreed that the following changes to Table S.2.5. of §5.56.(a) 

of NIST Handbook 44 should be forwarded to the S&T Committee for consideration:

• Add a note to Table S.2.5. to recognize the expanded scope of remote capability.

• Delete “remotely” from the second paragraph of Category 3 requirements that begins, “When accessed

remotely ...” to make it clear that the requirements of Category 3 apply whether accessed manually using 

the keyboard or accessed by remote means.

• Add the modified second paragraph of Category 3 requirements to Categories 3a and 3b to make it clear 

that these requirements apply to all the subcategories of Category 3.

After additional review of this item, NIST, OWM recommended that the changes to Table S.2.5. approved by the 

Sector in 2011 be separated into two independent proposals, one dealing with the changes to Category 3 and its 

subcategories (as shown in this proposal), and the other recommending a modification of the definition of remote 

configuration capability appearing in Appendix D of NIST Handbook 44 to recognize the expanded scope of remote 

capability, instead of adding a note to the bottom of Table S.2.5. to expand the definition of remote configuration for 

grain moisture meters. A change to the definition of remote configuration capability will apply to other device 

types.
S&T Committee 2013 Final Report

S&T - 62

2012 Grain Analyzer Sector Meeting: T he Sector agreed to separate its original proposal into two separate 

proposals and that the following changes to Table S.2.5. of §5.56.(a) of NIST Handbook 44 should be forwarded to 

the S&T Committee for consideration:

• Delete “remotely” from the second paragraph of Category 3 requirements that begins, “When accessed 

remotely ...” to make it clear that the requirements of Category 3 apply whether accessed manually using 

the keyboard or accessed by remote means.

• Add the modified second paragraph of Category 3 requirements to Categories 3a and 3b to make it clear 

that these requirements apply to all the subcategories of Category 3.

This proposal is consistent with the philosophy of sealing for grain moisture meters. Item 4 of the NTEP, Grain 

Analyzer Sector August 2012 Meeting Summary covers this subject and will be available on NCWM’s Website 

November 2012.

2012 CWMA Interim Meeting: CWMA forwarded the item to NCWM, recommending it as a Voting Item.

2012 WWMA Annual Meeting: Ms. Juana Williams (NIST, OWM) expressed general support for the intent of this

item; that the device should indicate when it is in configuration mode and not be capable of operating in the 

measuring mode. The Committee acknowledged the proposed recommendation from the NTEP Grain Analyzer 

Sector to add a note to Table S.2.5. to expand the scope of remote capability by modifying its definition for remote 

configuration capability as shown in S&T Item 356-3. T he Committee did not support that item. W WMA 

forwarded this item to NCWM, recommending it as a Voting Item.

2012 SWMA Annual Meeting: T here were no comments. T he Committee acknowledged that the proposal is 

supported by the NTEP Grain Sectors. Recognizing the expertise of the Sector members, the Committee believed it 

is appropriate to support the proposal as recommended by the Work Group. SWMA forwarded the item to NCWM, 

recommending it as a Voting Item.

2013 NCWM Interim Meeting Open Hearings: The Committee heard comments from Ms. Williams (NIST, OWM) 

who noted that OWM agrees with the Sector’s decision to separate their original proposal into two parts. OWM also 

agreed with the elimination of the note originally proposed for Table S.2.5. O WM also believes the proposed 

change to require Category 3 devices, including these classified as subcategories 3a and 3b devices clearly indicate 

when they are in the configuration mode and not be capable of operating in the measuring mode is appropriate. 

These proposed changes are generally consistent with the sealing requirements for all similar tables in Section 3 of 

NIST Handbook 44. The Committee may wish to consider proposing similar changes where appropriate in other 

NIST Handbook 44 device codes. The Committee heard no other comments on this item. Hearing no opposition to 

the proposed changes, the Committee agreed to recommend the proposal for a Vote.

2013 Annual Meetings of NEWMA and the CWMA: The associations supported this item as a Voting Item. On the 

NCWM Online Position Forum, one government representative supported the proposal, with no additional 

comments.

2013 NCWM Annual Meeting Open Hearings: T he Committee heard no comments in opposition to this item.

356-2 VC UR.3.4. Printed Tickets 

(This item was adopted.)

Source: 

Grain and Feed Association of Illinois (2012)

Purpose: 

Change the mandatory printing of tickets from grain moisture meters to an on demand at the time of transaction 

printing and remove the requirement of printing the calibration version identification. Note that the Committee did 

not agree with proposed removal of the requirement to print the calibration version identification; this position is 

reflected in the version of the proposal currently under consideration by the Committee.

Item Under Consideration: 

Amend paragraph UR.3.4. as follows:

UR.3.4. Printed Tickets.

(a) Printed tickets shall be free from any previous indication of moisture content or type of grain or seed 

selected.

(b) The customer shall be given a printed ticket at the time of the transaction or as otherwise specified 

by the customer. The printed ticket shall include showing the date, grain type, grain moisture 

results, test weight per bushel, and calibration version identification. The ticket information shall be 

generated by the grain moisture meter system.

(Amended 1993, 1995, and 2003, and 2013) 

Background/Discussion:

According to the submitter, the user requirement to provide a printed ticket for every single load is unrealistic in the 

country elevator industry. Traffic patterns at country elevators do not lend themselves to providing a printed ticket 

to all customers and customers really don’t want them. As the speed and capacity increases in the industry, 

outbound scales are being located at a distance from the inbound scale and the scale house where the moisture tester 

is located to alleviate traffic bottlenecks. When the outbound scale is located away from where the ticket is printed, 

the truck driver must circle back around to pick up the ticket, thus, causing logistical problems. In addition, since 

meters are sealed, inspected, and required to have the correct calibration, there is no need for the calibration version 

identification to be printed on the ticket. Also, most customers are not going to know if it is the correct calibration 

version identification or not. There have been problems getting the information from the grain moisture meter to the 

grain accounting system – especially the calibration version identification. Some grain accounting systems have to 

be “hard coded” for calibration version identification which must be changed whenever the calibration changes. The 

change will be at an added cost for the industry.

When a consumer pays at a gas pump, they have the option of a receipt on demand at the time of transaction or not 

receiving a receipt. There would be a cost savings to moisture meter users as they would save on paper and filing 

space, and in the situation where the calibration version identification is “hard coded,” there will be a cost savings of 

the expense to have the grain accounting software provider make those changes.

Since moisture meters are capable of printing the ticket, some would argue that they should just go ahead and print 

them and provide them to the customer. In addition, the requirement does not say when the ticket shall be given to 

the customer; thus, the printed tickets could be saved for weeks, months, or even years in case the customer had a 

concern at some point. Printing the calibration version identification ensures the correct calibration is being used.

The submitter proposed amendments to paragraph UR.3.4. Printed Tickets which would allow the customer to 

dictate whether or not a p rinted ticket is needed for a g iven transaction but would not require printing of the

calibration version identification on the ticket. In 2011 and 2012, the Committee received comments supporting 

changes to the language that would allow the customer to specify whether or not he or she wanted a printed ticket. 
S&T Committee 2013 Final Report

S&T - 64

However, the Committee heard opposition from the NTETC Grain Sector and others to deleting the calibration 

version information from the ticket. Consequently, the proposal was revised to maintain the reference to calibration 

version information as shown in the Item Under Consideration. Additional details can be found in the Committee’s 

2011 and 2012 Final Reports.

2012 CWMA Interim Meeting: I t was recommended that the item be Withdrawn; however, the association 

supported the item as a Voting Item at its 2013 Annual Meeting.

2012 WWMA Annual Meeting: The association received no comments on this item. The WWMA believed the 

intent in the amended proposed language is similar to other codes in NIST Handbook 44 and sufficiently gives 

options of how printed tickets are provided to the customer. WWMA supported the item and recommended that it 

be a Voting Item.

2012 NEWMA Interim Meeting and 2013 Annual Meeting: NEWMA supported this item as a Voting Item at both 

meetings. 

2012 SWMA Annual Meeting: The SWMA received no comments. The Committee recognized that the NCWM 

S&T Committee designated this as an Information Item to allow additional time for the weights and measures 

community, including the original submitter, to review the changes made to the proposal during the 2012 NCWM 

Interim Meeting. The Committee believes that adequate time has elapsed to allow for comment. The Committee 

noted that the NTEP Grain Analyzer Sector has also reviewed the proposal, as modified, and has expressed no 

opposition. SWMA recommended that the item be a Voting Item.

2013 NCWM Interim Meeting Open Hearings: The Committee heard comments from Ms. Juana Williams (NIST, 

OWM) who noted that OWM believes the suggested changes to UR.3.4. Printed Tickets are appropriate and notes 

that the language is similar to other codes in NIST Handbook 44. OWM agrees with the Grain Analyzer Sector’s 

decision to retain the requirement for recording the “calibration version identification.” NIST, OWM noted that 

while “Category 3” devices would require the printing of the calibration version identification information, not all 

grain moisture meters are “Category 3” devices. Having this information printed on receipts provides customers and 

officials with the means to verify that correct calibration settings are being used for a given transaction. T he 

Committee received no other comments on this item. Hearing no opposition to the proposed changes, the 

Committee agreed to recommend the proposal for a Vote.

On the 2013 NCWM Online Position Forum, one government representative opposed the proposal, with no 

additional comments.

2013 NCWM Annual Meeting Open Hearings: T he Committee heard no comments in opposition to this item. 

NIST, OWM reiterated its comments from the 2013 Interim Meeting.

[Nonretroactive as of January 1, 2004]

(Added 2003) (Amended 2006 and 20XX) 

Background/Discussion: 

Among other tasks, the NTEP Software Sector was charged by the NCWM Board of Directors to recommend NIST 

Handbook 44 specifications and requirements for software incorporated into weighing and measuring devices, 

which may include tools used for software identification. During its October 2007 meeting, the Sector discussed the 

value and merits of required markings for software, including possible differences in some types of software-based 

devices and methods of marking requirements. After hearing several proposals, the Sector agreed to the following 

technical requirements applicable to the marking of software:

1. The NTEP CC Number must be continuously displayed or hard-marked;

2. The version must be software-generated and shall not be hard-marked;

3. The version is required for embedded (Type P) software;

4. Printing the required identification information can be an option;
S&T Committee 2013 Final Report

S&T - 69

5. Command or operator action can be considered as an option in lieu of a continuous display of the required 

information; and

6. Devices with Type P (embedded) software must display or hard-mark the device make, model, and serial 

number to comply with G S.1. Identification.

In 2008, the Software Sector developed and submitted a proposal to the NCWM S&T Committee to modify G-S.1. 

and associated paragraphs to reflect these technical requirements. Between 2008 and 2011, this item appeared on 

the S&T Committee’s main agenda and the Committee and the Sector received numerous comments and suggestions 

relative to the proposal. The Sector developed and presented several alternatives based on feedback from weights 

and measures officials and manufacturers. Among the key points and concerns raised during discussions over this 

period were how to address the following:

1. Limited Character Sets and Space. – How to address devices that have limited character sets or restricted 

space for marking.

2. Built-for-Purpose vs. Not-Built-for-Purpose. - Whether or not these should be treated differently.

3. Ease of Access. – Ease of accessing marking information in the field.

• Complexity of locating the marking information

• Use of menus for accessing the marking information electronically

• Limits on the number of levels required to access information electronically

• Possibility of single, uniform method of access

4. Hard Marking vs. Electronic. – Whether or not some information should be required to be hard marked 

on the device.

5. Continuous Display. – Whether or not required markings must be continuously displayed.

6. Abbreviations and Icons. – Establishment of unique abbreviations, identifiers, and icons and how to 

codify those.

7. Certificate of Conformance Information. – How to facilitate correlation of software version information 

to a CC, including the use of possible icons.

Further details on the alternatives considered can be found in the Committee’s Final Reports from 2008 to 2011.

2011 NCWM Interim Meeting: The S&T Committee concurred with the Software Sector Chair that this item is not 

ready to move forward as a Voting Item. The Committee recommended the Sector review a number of specific 

comments and points (see the Committee’s 2011 Final Report for details.)

2011 NCWM Annual Meeting: The Committee heard support for the continued work of the Sector. The 2011 S&T

Committee designated this item as a Developing Item to provide the Software Sector additional time to more fully 

develop the item. The Committee looked forward to considering the Sector’s future recommendations. 

2011 fall Regional Meetings: The regional weights and measures associations noted the importance of this work. 

All regional associations recommended that the item remain as a Developing Item to allow the Sector to further 

develop the issue. The regional associations also reported a d esire to receive an update on the progress of the 

Software Sector regarding this item. T hree of the regions recommended the item remain Developing. NEWMA 

recommended the item be Withdrawn unless new information is introduced. 

2013 NCWM Interim Meeting: No comments were received relative to this item during the Open Hearings. In 

considering the item, the Committee questioned whether or not the Software Sector was still actively working the 

item. It was reported that the Software Sector believed they had developed the item as much as possible, yet the 

different stakeholders affected by the proposal could not agree on the changes that the Sector had proposed. Based 
S&T Committee 2013 Final Report

S&T - 70

upon that update, the Committee agreed to add to its report a r equest that the Software Sector work with the 

Weighing Sector and Measuring Sector to identify which portions of the proposal need to be modified in order that 

they might be accepted by the entire community. The Committee acknowledges and appreciates the efforts of the 

Software Sector and looks forward to being able to consider a proposal that addresses both the identification of 

software and how it may be accessed.

The following draft update from the Software Sector regarding this item was forwarded to the Committee just prior 

to the 2013 NCWM Annual Meeting:

Software Sector Meeting - March 2013: The Sector considers this item sufficiently developed. During the 2013 

Meeting, the Sector agreed to modify slightly the previously language to address some of the concerns received via 

feedback from other sectors and interested parties. The following changes to that language are proposed:

NIST Handbook 44 – Proposed changes:

G-S.1. Identification. – All equipment, except weights and separate parts necessary to the measurement process but not 

having any metrological effect, shall be clearly and permanently marked for the purposes of identification with the following 

information: 

(a) the name, initials, or trademark of the manufacturer or distributor; 

(b) a model identifier that positively identifies the pattern or design of the device; 

(1) The model identifier shall be prefaced by the word “Model,” “Type,” or “Pattern.” These terms may be 

followed by the word “Number” or an abbreviation of that word. The abbreviation for the word “Number” 

shall, as a minimum, begin with the letter “N” (e.g., No or No.). The abbreviation for the word “Model” 

shall be “Mod” or “Mod.” Prefix lettering may be initial capitals, all capitals, or all lowercase.

(2) Abbreviations for the word “Serial” shall, as a minimum, begin with the letter “S,” and abbreviations for the 

word “Number” shall, as a minimum, begin with the letter “N” (e.g., S/N, SN, Ser. No., and S. No.). 

[Nonretroactive as of January 1, 2001] 

(d) the current software version or revision identifier for not-built-for-purpose software-based electronic devices,

which shall be directly linked to the software itself; 

[Nonretroactive as of January 1, 2004] 

(Added 2003) (Amended 20XX)

(1) The version or revision identifier shall be prefaced by words, an abbreviation, or a symbol, that clearly 

identifies the number as the required version or revision. 

[Nonretroactive as of January 1, 2007] 

(Added 2006) 

(2) Abbreviations for the word “Version” shall, as a minimum, begin with the letter “V” and may be followed by 

the word “Number.” Abbreviations for the word “Revision” shall, as a minimum, begin with the letter “R” 

and may be followed by the word “Number.” The abbreviation for the word “Number” shall, as a minimum, 

begin with the letter “N” (e.g., No or No.).

S&T Committee 2013 Final Report

S&T - 71

(3) The version or revision identifier shall be accessible via the display. Instructions for displaying the version 

or revision identifier shall be described in the CC. As an exception, permanently marking the version or 

revision identifier shall be acceptable under the following conditions:

i. The user interface does not have any control capability to activate the indication of the version or 

revision identifier on the display, or the display does not technically allow the version or revision 

identifier to be shown (analog indicating device or electromechanical counter) or

ii. the device does not have an interface to communicate the version or revision identifier.

(e) an NTEP CC number or a corresponding CC Addendum Number for devices that have a CC. 

(1) The CC Number or a corresponding CC Addendum Number shall be prefaced by the terms “NTEP CC,” 

“CC,” or “Approval.” These terms may be followed by the word “Number” or an abbreviation of that word. 

The abbreviation for the word “Number” shall, as a minimum, begin with the letter “N” (e.g., No or No.) 

[Nonretroactive as of January 1, 2003] 

The required information shall be so located that it is readily observable without the necessity of the disassembly of a part 

requiring the use of any means separate from the device. (Amended 1985, 1991, 1999, 2000, 2001, 2003, and, 2006 and 

20XX) 

G-S.1.1. Location of Marking Information for Not-Built-For-Purpose All Software-Based Devices. – For not-builtfor-purpose, software-based devices, either: 

(a) The required information in G-S.1. Identification. (a), (b), (d), and (e) shall be permanently marked or 

continuously displayed on the device; or 

(b) The CC Number shall be: 

(1) permanently marked on the device; 

(2) continuously displayed; or 

(3) accessible through an easily recognized menu and, if necessary, a submenu. Examples of menu and 

submenu identification include, but are not limited to, “Help,” “System Identification,” “G-S.1. 

Identification,” or “Weights and Measures Identification.” 

Note: For (b), clear instructions for accessing the information required in G-S.1. (a), (b), and (d) shall be listed on the 

CC, including information necessary to identify that the software in the device is the same type that was evaluated. 

[Nonretroactive as of January 1, 2004] 

(Added 2003) (Amended 2006 and 20XX) 

The Sector reported that the new language in G-S.1.1 reflects that the Sector reached consensus on the following 

positions:

• The software version/revision should (with very few exceptions – see D-31, 5.1.1.) be accessible via the 

user interface.

• The means by which the software version is accessed must be described in the Certificate of Conformance 

(CC).

The Sector noted that since the 2012 meeting, the Sector has attempted to promote this item via several means to try 

and address the concerns of other interested parties. A presentation was generated and shared with the S.M.A. at 

their 2012 meeting. Most of the regions had access to this information prior to their meetings, as it was posted on 

the NCWM website. Unfortunately, based on the comments in the 2013 NCWM Publication 15, Item 360-2, some 

regions were not aware that this information had been made available. The Sector also noted that they may want to 

consider more direct methods, in other words, designating a representative to address the regional groups or other 

sectors at their meetings. The Annual Meeting may be an appropriate venue for a p resentation. To move this 
S&T Committee 2013 Final Report

S&T - 72

forward, someone should address the regional groups. There are five to six potential venues for presentations. The 

last slide from the current presentation should be eliminated, to avoid confusing matters, for the time being. The 

two regional meetings in the fall (Western and Southern) and the Interim Meeting are probably more critical than the 

ones in May. Dr. Thompson was asked to relay that we have a presentation available and would like to push our 

proposal as a Voting Item in 2014. 

After removing the “and inseparably” terminology from the proposal, the concerns on the possibility of controversy 

were reduced.

The Sector’s opinion on the interpretation of “directly linked” is that it means that you can’t change the 

version/revision without changing the software.

In addition, it was noted that it may be desirable to evaluate options that would lead to fully eliminating G-S.1.1. It 

was noted that this would be a more invasive modification to the existing Handbook and perhaps should be put off 

until the first step of addressing software in all devices (not just standalone) was accomplished.

The one response to our request for review/comment that contained negative feedback was undeniably vague and 

non-constructive. The issue seems to be more one of communication/understanding than disagreement with the 

intent or wording. 

It was recommended that a couple examples be added to the current slide presentation, to illustrate the intent of the 

proposed changes. One example might be supermarket-specific software designed to run upon a cash register. 

Another example might be, after a s oftware change, noting that the new software version/revision number is no 

longer the same, and the operator was not prompted to enter a version/revision number.

2013 NCWM Annual Meeting Open Hearings: The Committee heard a comment from Mr. Tim Tyson (Kansas), 

who recognized the Sector’s work on this item and suggested that consideration be given to changing the status of 

the item to Informational status. In considering this suggestion during its work session, the Committee agreed that 

the change might be appropriate; however, decided instead to seek input from the NTEP Sectors and industry 

associations before making that decision. Consequently, the Committee requested that the Sectors and industry 

associations review the Software Sector’s latest proposal at their next meetings. 

360-3 D Part 3.30. Price Posting and Computing Capability and Requirements for a Retail 

Motor-Fuel Dispenser (RMFD)

Source: 

NIST, OWM and the Regional Weights and Measures Associations (2008)

Purpose: 

Review and update criteria in the LMD Code related to price posting and computing capability of RMFDs to reflect 

current market practices. 

Item under Consideration: 

The NCWM Task Group on RMFD Price Posting and Computing Capability developed specific proposals for 

modifying the LMD Code to address price posting and computing requirements for RMFDs. These proposals were 

adopted by the NCWM in 2012 and published in the 2013 NIST Handbook 44; they are being revisited at the 

request of the NCWM S&T Committee who has asked the Task Group to complete its review of sample receipts and 

provide guidance on applying the new criteria. Item 360-3 is being retained as a Developing Item pending any 

additional assignments that may be given by the Committee to the Task Group relative to the implementation of new 

code requirements that may be adopted. C omments or inquiries may be directed to NIST Technical Advisor, 

Ms. Juana Williams, at (301) 975-3989 or juana.williams@nist.gov. 
S&T Committee 2013 Final Report

S&T - 73

Background/Discussion: 

In the early 1990s, various sections of the LMD Code in NIST Handbook 44 were modified to address multi-tier 

pricing applications in instances where the same product is offered at different unit prices based on the method of 

payment (such as cash or credit) or other conditions of the sale. Since that time, marketing practices have evolved to 

include the addition of new practices, such as frequent shopper discounts and club member discounts. Numerous 

questions have been posed to NIST OWM and weights and measures officials regarding the requirements for 

posting unit prices, calculation of total price, customer-operated controls, and other related topics, such as 

definitions for associated terminology. I t is clear from these questions that changes are needed to NIST 

Handbook 44 to ensure the requirements adequately address current marketplace conditions and practices. The 

Committee agreed that changes are needed to the LMD Code relative to these issues, and in 2010 the Committee 

established a t ask group to further develop this issue and present an alternative recommendation for its 

consideration.

Additional details on this item can be found in the Committee’s 2008 - 2012 Final Reports.

2012 WWMA Annual Meeting: Ms. Williams reported that the NCWM Task Group (TG) on RMFD Price Posting 

and Computing Capability recently reviewed and approved NIST editorial changes to NIST Handbook 44, Section

3.30. Liquid-Measuring Devices, paragraph S.1.6.5.4. Selection of Unit Price. The TG Chair, Ms. Fran 

Elson-Houston (Ohio), continues to communicate with the NCWM S&T Committee Chairman and the NCWM 

Chairman to determine if the TG has any remaining assignments. Mr. Kurt Floren (Los Angeles County, California)

encouraged feedback and input after everyone reviews the six paragraphs that will go into NIST Handbook 44 

January 2013. He also suggested reviewing how these changes affect real life applications. The WWMA suggested 

the TG remain in place for at least a year after implementation of these six new requirements because it has the best 

knowledge of this issue to deal with any implementation issues that surface. WWMA recommended that the item 

remain as a Developing Item.

2012 NEWMA Interim Meeting: The association supported the efforts of the working group and recommended that 

the item remain as a Developing Item.

2012 SWMA Annual Meeting: The NCWM S&T Chairman reported that the NCWM S&T Committee has asked 

the RMFD Price Posting and Computing Capability TG to continue developing guidelines and examples, including 

sample receipt layouts, to illustrate how the changes to the LMD Code adopted in July 2012 are intended to be 

implemented. T he SWMA looks forward to the TG’s development of these guidelines. S WMA unanimously 

recommended that the item remain as a Developing Item while the TG continues its work.

2013 NCWM Interim Meeting Open Hearings: T he Committee heard a s uggestion from Ms. Elson-Houston, 

speaking as Chair of the TG on RMFD Price Posting and Computing Capability on a TG proposal, to further modify 

paragraph UR.3.3. Computing Device. Ms. Elson-Houston reported that the TG had met and agreed: 1) to develop 

sample receipts for transactions where motor fuel pricing is discounted after the delivery; 2) the Chair would provide 

input on the “Do’s and Don’ts” for complying with the requirements that went into effect January 2013 for posting 

on The Oil Express web newsletter; and 3) to recommend additional amendments to paragraph UR.3.3., which were 

provided to the Committee. During its deliberations, the Committee reviewed the proposed changes recommended

by the TG and agreed to establish a new Informational Item to address those modifications. The Committee also 

agreed to retain Developing Item 360-3 while the TG continues work to develop guidelines and examples on how 

the changes made last year to the LMD Code will apply to receipts for post-delivery discounted transactions. The 

above new information item established by the Committee is available in S&T Agenda Information Item 330-4 and 

is included in the section of this report that addresses Liquid-Measuring Devices Code requirements.

2013 NEWMA and CWMA Annual Meetings: Both associations supported this as a Developing Item. During the 

NEWMA meeting, Ms. Tina Butcher reported that Ms. Elson-Houston, Chairman of the Task Group, had been in 

contact with the NCWM S&T Committee Chair, Mr. Ken Ramsburg. Ms. Elson-Houston advised NIST that 

Mr. Ramsburg (Maryland, NCWM S&T Committee Chairman) is planning to suggest that the S&T Committee ask 

the NTEP Measuring Sector to develop further guidelines for use in type evaluation and, should additional 

assistance be needed after that point, to re-establish the Task Group at that time. NEWMA defers to the national 

S&T Committee to determine the continued need for this item.
S&T Committee 2013 Final Report

S&T - 74

On the 2013 NCWM Online Position Forum, one government representative indicated support for this item with no 

additional comments.

2013 NCWM Annual Meeting: T he Committee heard comments from Ms. Williams who emphasized the 

importance of continuing to develop guidelines and information to assist regulatory officials and industry in 

interpreting and applying requirements relative to pre- and post-delivery discounts. NIST OWM is working on the 

development of guidelines and examples that could be included in NIST EPOs and training materials and has 

already received positive feedback from members of the Task Group on the examples developed thus far. This 

information may also be of use to NTEP in the further development of checklist criteria for inclusion in NCWM 

Publication 14. OWM will continue to develop this information and make it available in updates to EPOs and 

course materials and would appreciate additional input from the community.

Ms. Beth Treseder (API) indicated that API and others within industry would appreciate copies of acceptable 

receipts as they become available.

The Committee believes that additional work is needed to develop examples and information that will enable 

consistent and uniform application of the requirements adopted in 2012 and encourages OWM’s continued work on 

such examples. The Committee asks that the Task Group continue its work by developing and providing additional 

examples of acceptable receipts to assist regulatory officials and industry in interpreting and applying these 

requirements. The Committee believes that examples of receipts from deliveries that include both pre- and postdelivery discounts in a single transaction are needed.

360-5 D USNWG on Taximeters – Taximeter Code Revisions and Global Positioning 

System-Based Systems for Time and Distance Measurement

Note: This item was originally titled “Item 360-5 S.5. Provision for Security Seals” in the Committee’s 2013 

Interim Agenda. At the 2013 NCWM Interim Meeting, the Committee combined that item with “Item 354-1 

Global Positioning Systems for Taximeters” and “Item 360-6 Global Positioning Systems for Taximeters” to 

create this new, consolidated item to address the development of recommendations on multiple topics related to 

taximeters and GPS-based time and distance measuring systems.

NIST USNWG on Taximeters

Purpose: 

Develop recommendations for modifying the existing Taximeters Code to reflect current technology (including 

requirements for sealing, display requirements, and other features) and to examine GPS-based time and distance 

measuring systems to determine how to best address these measuring systems in NIST Handbook 44 to ensure 

accuracy and transparency for passengers and businesses.

Item Under Consideration: 

This item is under development. Comments and inquiries may be directed to Mr. John Barton (NIST OWM) at 

(301) 975-4002 or john.barton@nist.gov. 

The USNWG is considering proposals to modify the sealing requirements in the Taximeters Code to reflect more 

advanced sealing methods (see 2012 NCWM Final S&T Report); to amend the Taximeters Code to specifically 

recognize GPS-based time and distance measuring systems; and to amend other sections of the Taximeters Code to 

reflect current technology and business practices while ensuring accuracy and transparency for customers and a level 

playing field for transportation service companies.
S&T Committee 2013 Final Report

S&T - 75

Background/Discussion:

In January 2012, the Committee considered a proposal from Frias Transportation Infrastructure, LLC to modify 

Taximeters Code paragraph S.5. Provision for Security Seals to recognize more advanced methods of sealing. See 

Item 360-5 in the Committee’s 2012 Final Report for details. This item appeared as “Item 360-5 S.5. Provision for 

Security Seals” in the Committee’s 2013 Interim Agenda. 

In January 2013, the Committee also considered a proposal from the City of Seattle’s Consumer Affairs to amend 

NIST Handbook 44, Section 5.54. Taximeters to make it s pecifically apply to Global Positioning System (GPS) 

system applications used commercially to compute fares based upon distance and/or time measurements. S ee 

Item 360-6 in the Committee’s 2012 Final Report for details; this item appeared as “Item 360-6 Global Positioning 

Systems for Taximeters” in the Committee’s 2013 Interim Agenda.

In April 2012, in response to requests from the NCWM and members of the weights and measures community, 

NIST, OWM formally established a USNWG on Taximeters. The purpose of the USNWG was to continue work 

already in progress at NIST to develop proposed changes to the Taximeters Code to reflect current technology and 

to provide a forum in which stakeholders could work together to address issues such as those outlined in Items 360-5 

and 360-6 on the Committee’s 2012 Agenda. T he USNWG includes participants from the taxi/vehicle-for-hire 

industry (owners & operators), manufacturers and developers of taximeters and taximeter systems, regulatory 

officials, and technical experts.

2012 WWMA Annual Meeting: Ms. Williams submitted a status report for NIST USNWG on Taximeters. 

Ms. Kristin Macey (California) expressed strong interest in the issue of GPS system applications being used to 

compute fares based upon distance and/or time. Currently, California DMS is the only NTEP type approval lab and 

while they look forward to having a device submitted, they wouldn’t know what to do with the request. She 

opposed the carryover item (Item 360-6 Global Positioning Systems for Taximeters on the NCWM S&T 

Committee’s Agenda) and asked that it b e withdrawn, stating that it might be better considered under a new, 

separate code section. Mr. John Gaccione (Westchester County, New York) expressed other consumer concerns, 

such as access to receipts, the need of expensive smart phones, and that currently there is no regulatory oversight, 

whereas there are over 13,000 taxis now operating in that jurisdiction. Mr. Miguel Monroy (San Francisco, 

California), echoed Ms. Macey’s concern that there was no regulatory oversight and that GPS systems have been 

active in his jurisdiction for two years. T he WWMA concluded that it d idn’t have enough information on 

metrological accuracy of GPS in measurement of distance and time, and there may be other metrological parameters 

that will be part of the charges. 

2012 SWMA Annual Meeting: Ms. Tina Butcher (NIST, OWM) submitted a status report for the NIST USNWG on 

Taximeters.

All of the regional weights and measures associations support the efforts of the USNWG. T he WWMA and the 

SWMA further recommended that the NCWM S&T Committee consider consolidating the related items on 

Taximeters and GPS-based systems into a single item and designating the contact point as the USNWG.

2013 NCWM Interim Meeting: The Committee considered another proposal from the City of Seattle’s Consumer 

Affairs to amend NIST Handbook 44, Section 5.54. Taximeters to make it specifically apply to Global Positioning 

System (GPS) system applications used commercially to compute fares based upon distance and/or time 

measurements. T his proposal was designated as Item 354-1 in the Committee’s Interim Agenda. No proposed 

language modifying the current Taximeters Code was submitted. At its fall 2012 Annual Meeting, the WWMA 

considered this item; this item was not submitted to the other regional associations. The WWMA noted that this 

item is similar to Item 360-6 in the NCWM S&T Committee’s 2012 Final Report; like that item, it seeks to develop 

the Taximeter Code to apply specifically to GPS applications inputs and software programming in smart phone 

applications used commercially to compute fares based upon distance and/or time measurements. The WWMA 

forwarded the item to NCWM S&T Committee and recommended that it be combined with the item designated in 

the NCWM S&T Committee’s Final Report as Developing “Item 360-6, Global Positioning Systems for 

Taximeters” and be addressed by the NIST USNWG on Taximeters; however, this item was designated as 

Item 354-1 on the NCWM S&T Committee’s 2013 Interim Agenda.
S&T Committee 2013 Final Report

S&T - 76

2013 NCWM Interim Meeting Open Hearings: The Committee heard comments under Item 354-1 in support of 

work to further develop requirements to address GPS-based systems and to continue work on proposed revisions to 

the Taximeter Code to reflect current technology. NIST OWM provided the following update on the progress of the 

USNWG:

The USNWG on Taximeters held its first face-to-face meeting at NIST’s Gaithersburg facility 

September 24 - 26, 2012. To provide the USNWG with necessary input and analysis regarding the capability of the 

GPS system, expertise in that area was solicited. A staff member from the NIST Time and Frequency Division has 

agreed to assist the USNWG in matters related to GPS and act as an observing member of the USNWG. While the 

September 2012 meeting was very productive, a great deal of work remains to be completed. Additional meetings 

are anticipated; the next meeting is scheduled via web conference for March 13, 2013, from 1:30 p.m. to 4:00 p.m. 

EST. The direction of the USNWG’s continuing work will take place in the form of two concurrent projects. 

The main body of the work group will target the completion of updating the existing Taximeters Code so that 

specifications and requirements apply to devices and technologies currently in use in this industry. The work of the 

USNWG will result in proposals to amend the Taximeters Code and NCWM Publication 14 where needed. Those 

proposals will then be submitted for consideration by the NCWM.

In addition to the work in updating the existing Taximeters Code, a Subcommittee is being formed and will 

specifically work towards the development of standards and requirements that will address the use of GPS as a 

source of commercial time and distance measurements. The work will involve amendment as needed of existing 

specification and performance requirements and the possible development of new requirements that will encompass 

the use of GPS.

This Subcommittee will also develop the necessary standards and test procedures for the evaluation of 

transportation-for-hire services that have recently been introduced using mobile telephone applications (apps) in the 

process of requesting, dispatching, and the calculation of fares for these services.

Mr. James Cassidy (City of Cambridge, Massachusetts), a member of the USNWG, rose in support of these efforts, 

and to encourage others with interest and expertise to participate in the work. The Committee also heard comments 

from Mr. Ross Andersen (New York, retired) who reflected on differences between standard length-measuring 

devices such as steel tapes and GPS-based systems. He also noted the need to address electronic receipts in any 

proposed revisions to the language.

The Committee heard no comments on Items 360-5, S.5. Provision for Security Seals; or 360-6 Global Positioning 

Systems for Taximeters during its Open Hearings. After considering the summary of the work being done by the 

USNWG; the comments heard during its Open Hearings; and comments from the regional associations regarding the 

overlap among these related items, the Committee decided to consolidate Item 354-1 Global Positioning Systems for 

Taximeters; Item 360-5 S.5. Provision for Security Seals; and Item 360-6 Global Positioning Systems for 

Taximeters into a single Developing Item, and to designate the USNWG on Taximeters as responsible for the item’s 

development.

2013 NEWMA and CWMA Annual Meetings: Both associations supported this as a Developing Item. NEWMA 

heard updates from NIST and USNWG Members on the USNWG. NEWMA also heard comments from a member 

about whether or not GPS-based systems could ever provide comparable measurements to conventional taxi meters 

given how GPS systems work as they do not recognize changes in elevation. NEWMA noted the immediate need

by some jurisdictions for this item and supports the work of the USNWG to move this item forward.

On the 2013 NCWM Online Position Forum, two government representatives supported continued development of 

the proposal by the USNWG. One government representative indicated a neutral position, noting that these devices 

are not regulated by the weights and measures authority in his state. Technical Advisor’s note: The results and 

comments from the Forum reflect the combined positions and comments for S&T agenda Items 354-1 and 360-5, 

which were combined at the 2013 NCWM Interim Meeting to create this new consolidated agenda item.
S&T Committee 2013 Final Report

S&T - 77

2013 Annual Meeting Open Hearings: T he Committee heard an update on the work of the USNWG from 

Ms. Williams. She noted that the USNWG held a teleconference on July 10 and has established a Subcommittee to 

address GPS-based time and distance measuring systems. The USNWG meets about every other month via either 

web or in-person meetings. Mr. John Barton (NIST OWM) Chair and Technical Advisor to the USNWG further 

noted that the USNWG includes an expert in GPS measurements from NIST’s Time and Frequency Division, 

Mr. Mike Lombardi.

The Committee heard comments from Mr. Andersen, who questioned whether or not GPS-based systems account 

for variations in elevation. Other members commented that many GPS based devices do have the capability to 

account for these changes.

The Committee encourages the continued work of the USNWG and looks forward to continued developments in this 

area.

360-6 D Global Positioning Systems for Taximeters

Note: At the 2013 NCWM Interim Meeting, the Committee combined this item with “Item 354-1 Global 

Positioning Systems for Taximeters” and “Item 360-5, S.5. Provision for Security Seals” to create a new, 

consolidated Developing Item. The consolidated Developing Item is designated as “Item 360-5 USNWG on 

Taximeters – Taximeter Code Revisions and Global Positioning Systems for Time and Distance Measurement.” 

See Item 360-5 for details.

360-7 D Appendix D – Definitions: Remote Configuration Capability 

Source: 

NTEP Grain Analyzer Sector (2013)

Purpose: 

Expand the scope of definition to cover instances where the “other device,” as noted in the current definition, may 

be necessary to the operation of the weighing or measuring device or which may be considered a permanent part of 

that device.

Item Under Consideration: 

This item is under development. C omments and inquiries may be directed to NIST Office of Weights and 

Measures.

A proposal to modify the definition for “remote configuration capability” as follows is under consideration:

remote configuration capability. – The ability to adjust a weighing or measuring device or change its sealable 

parameters from or through some other device that is not may or may not itself be necessary to the operation 

of the weighing or measuring device or is not may or may not be a permanent part of that device.[2.20, 2.21, 

2.24, 3.30, 3.37, 5.56(a)]

(Added 1993) (Amended 20XX) 

Background/Discussion:

Removable digital storage devices can be used in GMMs either as data transfer devices that are not necessary to the 

operation of the GMM or as data storage devices that are necessary to the operation of the GMM. If removal data 

storage devices are necessary to the operation of the device, they are not covered by the current definition of remote 

configuration capability. 

A USB flash drive is most likely to be used as a data transfer device. In a typical data transfer application, the USB 

flash drive is first connected to a computer with access to the GMM manufacturer’s web site to download the latest 

grain calibrations that are then stored in the USB flash drive. The USB flash drive is removed from the computer 
S&T Committee 2013 Final Report

S&T - 78

and plugged into a USB port on the GMM. The GMM is put into remote configuration mode to copy the new grain 

calibration data into the GMM’s internal memory. W hen the GMM has been returned to normal operating 

(measuring) mode, the USB flash drive can be removed from the GMM.

Although a Secure Digital (SD) memory card could also be used as a data transfer device it is more likely to be used 

as a d ata storage device. I n a t ypical “data storage device” application, the SD memory card stores the grain 

calibrations used on the GMM. The SD memory card must be plugged into an SD memory card connector on a 

GMM circuit card for the GMM to operate in measuring mode. To install new grain calibrations the GMM must be 

turned “off” or put into a mode in which the SD memory card can be safely removed. The SD memory card can 

either be replaced with an SD memory card that has been programmed with the new grain calibrations or the original 

SD memory card can be re-programmed with the new grain calibrations in much the same way as that described in 

the preceding paragraph to copy new grain calibrations into a USB flash drive. In either case, the SD memory card 

containing the new calibrations must be installed in the GMM for the GMM to operate in measuring mode. In that 

regard, the SD memory card (although removable) can be considered a p ermanent part of the GMM in that the 

GMM cannot operate without it.

Note: In the above example, the SD memory card could be any removable flash memory card such as the Secure 

Digital Standard-Capacity, the Secure Digital High-Capacity, the Secure Digital Extended-Capacity, and the Secure 

Digital Input/Output, which combines input/output functions with data storage. These come in three form factors: 

the original size, the mini size, and the micro size. A Memory Stick is a removable flash memory card format, 

launched by Sony in 1998, and is also used in general to describe the whole family of Memory Sticks. In addition to 

the original Memory Stick, this family includes the Memory Stick PRO, the Memory Stick Duo, the Memory Stick 

PRO Duo, the Memory Stick Micro, and the Memory Stick PRO-HG.

At its 2011 Grain Analyzer Sector Meeting the Sector agreed by consensus that the following changes to 

Table S.2.5. of Section 5.56.(a) of NIST Handbook 44 should be forwarded to the S&T Committee for 

consideration:

• Add a note to Table S.2.5. to recognize the expanded scope of remote capability.

• Delete “remotely” from the second paragraph of Category 3 requirements that begins, “When 

accessed remotely...” to make it clear that the requirements of Category 3 apply whether accessed 

manually using the keyboard or accessed by remote means.

• Add the modified second paragraph of Category 3 requirements to Categories 3a and 3b to make it clear 

that these requirements apply to all the subcategories of Category 3.

After additional review of this item, NIST, OWM recommended that the changes to Table S.2.5. approved by the 

Sector in 2011 be separated into two independent proposals: one dealing with the changes to Category 3 and its 

subcategories; and one recommending a modification of the definition of “remote configuration capability” 

appearing in Appendix D of NIST Handbook 44 to recognize the expanded scope of remote capability, instead of 

adding a note to the bottom of Table S.2.5. to expand the definition for remote configuration for grain moisture 

meters (as shown in this proposal). A change to the definition of remote configuration capability will apply to other 

device types. 

At its 2012 Meeting, the Grain Analyzer Sector agreed to separate its original proposal into two separate proposals 

and agreed to forward this proposal to change the definition of “remote configuration capability” to the S&T to 

Committee for consideration. (See also August 2012 NTEP Grain Analyzer Sector Summary, Item 5.) 

2012 WWMA Annual Meeting: Ms. Juana Williams (NIST, OWM) supported the intent. She talked about this item 

in conjunction with Item 356-1, S.2.5. Categories of Device and Methods of Sealing. This is a complex item 

affecting multiple other devices; therefore, the proposal requires further consideration. The language in the proposal 

to amend the definition of remote configuration capability is confusing. The Committee believes the current 

definition already allows the use of remote configuration devices and allows the flexibility desired. The 
S&T Committee 2013 Final Report

S&T - 79

ramifications of changing the definition could affect other devices in NIST Handbook 44. WWMA did not forward 

this item to NCWM.

2012 SWMA Annual Meeting: There were no comments. A fter reviewing the proposal and considering the

potential impact on other device types, the Committee recommended this as a Developing Item. The Committee 

asks that the Sector continue to obtain input on the definition and the impact the changes would have on other device 

types. SWMA forwarded the item to NCWM, recommending it as a Developing Item and assigning its development 

to the Grain Analyzer Sector.

2013 NCWM Interim Meeting Open Hearings: The Committee heard comments from Ms. Williams. NIST, OWM 

suggested the Committee consider this item as a Developing Item to allow other sectors to discuss how a change to 

the definition may affect other device types of similar design and to consider changes, if needed. NIST, OWM 

recognizes that the current definition for “remote configuration capability” may not address those grain moisture 

meters (GMMs) that can only be operated with a removable data storage device, containing, among other things, the 

grain calibrations intended for use with the GMM, inserted in the device (as was described by the Grain Analyzer 

Sector). As such, OWM noted that current sealing requirements were developed at a time when such technology 

likely didn’t exist, nor could be envisioned, and are based on the current definition of remote configuration 

capability. Because the current definition was never intended to apply to this “next generation” technology, NIST,

OWM suggested that those charged with further development of this item may wish to revisit the five philosophies 

of sealing and consider whether a new paragraph, completely separate from current sealing requirements, might be 

appropriate and a better option, than the one currently proposed. The five philosophies of sealing are included in the 

1992 Report of the 77th National Conference on Weights and Measures (Report of the Specifications and Tolerances 

Committee). Another option, preferred over the changes currently proposed, would be to add a separate statement to 

the current definition of “remote configuration capability” to address removable storage devices. For example, the 

following sentence might be considered as an addition to the current definition for “remote configuration 

capability:”

Devices which are programmed using removable media (such as SD cards, flash drives, etc.) that may or 

may not be required to remain with the device during normal operation are also considered to be 

remotely configured devices. 

The Committee also heard comments from Mr. Dmitri Karimov (Liquid Controls Corporation, LLC), speaking on 

behalf of the MMA, who made two points: 1) Flow computers may already have these capabilities, thus it may be 

more appropriate to consider adding requirements to the General Code so that the requirements will be uniformly 

applied to all device types; and 2) the Committee should look ahead and consider other capabilities that may or 

already have emerged such as wireless communication and configuration.

The Committee acknowledged the comments indicating that the current definition of “remote configuration 

capability” was developed at a time when certain technologies, such as blue tooth, SD storage devices, flash drives, 

and other media didn’t exist. The Committee recognized that it may be difficult to modify the existing definition 

and associated requirements to be flexible enough to address emerging and future technologies without having a 

significant (and possibly detrimental impact) on existing devices. Consequently, rather than modifying the current 

definition, the Committee concluded that a better approach might be to develop an entirely separate set of security 

requirements that would apply to emerging technologies. The Committee believes that additional work is needed to 

develop proposed definition(s) and associated requirements and decided to designate the item as Developmental. 

The Committee requests other sectors review the Grain Sector’s proposed modification to the definition as well as 

NIST, OWM’s suggestions and provide input.

2013 NEWMA and CWMA Annual Meetings: Both associations supported this as a Developing Item. NEWMA 

heard from NIST who encouraged members to consider this work as it applies to all device types.

On the 2013 NCWM Online Position Forum, one government representative indicated a neutral position on this item 

with no additional comments.

2013 NCWM Annual Meeting Open Hearings: The Committee heard comments from Ms. Williams who reiterated 

NIST, OWM’s comments from the 2013 Interim Meeting, suggesting that it may be appropriate to develop separate 
S&T Committee 2013 Final Report

S&T - 80

requirements to address new and future technologies that can be remotely configured with removable media. NIST, 

OWM plans to develop draft language and ask for input from the various Sectors at their upcoming meetings. 

Ms. Williams also noted the suggestion made at the 2013 NCWM Interim Meeting by Mr. Karimov speaking on 

behalf of the MMA, that a provision might be added to the General Code to address this type of equipment.

Ms. Julie Quinn (Minnesota) agreed with NIST, OWM’s comments and indicated support for possibly including 

requirements in the General Code to address newer and emerging technologies. Mr. Karimov, speaking on behalf of 

MMA, concurred with this suggestion.

“Diesel Gallon Equivalent (DGE)” of Natural Gas as a Vehicular Fuel 

Clean Vehicle Education Foundation

Development of the “Gasoline Gallon Equivalent” by NCWM*

In 1993, under the auspices of the National Conference on Weights and Measures 

(NCWM), a Compressed Natural Gas (CNG) Working Group came together to 

determine the way in which CNG would be sold to the public at retail as a motor fuel. . 

The working group focused on three issues:

1. How to provide the Natural Gas Vehicle (NGV) industry a method of sale that 

would be familiar and acceptable to consumers

2. How to provide weights and measures officials a verifiable and quantifiable 

means to determine the accuracy of natural gas dispensers; and

3. How to meet these requirements with a uniform, national standard.

NCWM considered three proposals for the method of sale of CNG:

1. joules, the unit of energy measurement in SI units

2. mass 

3. the Gasoline Gallon Equivalent (GGE)

The Natural Gas Vehicle Coalition (now NGVAmerica) recommended that the Gasoline 

Gallon Equivalent be adopted as the method of sale for CNG, and that it be based on 

the energy equivalent of a gallon of gasoline. The use of the GGE was recommended 

primarily for the convenience of the retail customer comparing the cost and fuel 

economy of a natural gas vehicle to a comparable gasoline vehicle. During the 

discussion, a proposal was made to eliminate the reference to energy content of CNG 

and replace it with a fixed conversion factor based on mass, with the fixed mass of CNG 

being equal to a gallon of gasoline. Measurement of mass in the retail dispenser and

verification by W&M officials is easier and less costly than measurement of energy 

content.

Since the energy content of a unit measure of CNG (standard cubic foot - scf) and 

gasoline (gallon) vary widely depending on the sample of fuel measured, the reference 

gallon of gasoline was determined to be Indolene, the gasoline used by EPA to certify 

emissions and fuel economy, with an energy content (lower heating value) of 114,118 

BTU/gal. Work conducted by the Institute of Gas Technology and the Gas Research 

Institute (now combined into the Gas Technology Institute) surveyed 6811 samples of 

natural gas nationwide and concluded that the “average” natural gas in the US had an 

energy content (lower heating value) of 923.7 BTU/scf, and a density of 0.0458172 

lbs/cubic foot. This translates 20,160.551 BTU/lb. Dividing gasoline’s 114.118 BTU/gal 

by natural gas’s 20,160.551 BTU/lb gives 5.660 lbs of natural gas = 1 GGE. Similar 

calculations determined that a gasoline liter equivalent of natural gas equals 0.678 kg of 

natural gas.

At its 79th annual meeting in July of 1994, NCWM adopted resolutions that:

“All natural gas kept, offered or exposed for sale or sold at retail as a 

vehicle fuel shall be in terms of the gasoline liter equivalent (GLE) or 

gasoline gallon equivalent (GGE), and 

All retail natural gas dispensers shall be labeled with the conversion factor

in terms of kilograms or pounds. The label shall be permanently and 

conspicuously displayed on the face of the dispenser and shall have either 

the statement “1 Gasoline Liter Equivalent (GLE) is equal to 0.678 kg of 

Natural Gas” or “1 Gasoline Gallon Equivalent (GGE) is equal to 5.660 lbs 

of Natural Gas” according to the method of sale used.”

These statements can be found in NIST Handbook 130*, along with the definition of 

“natural gas” which seems to apply only to Compressed Natural Gas, not to Liquefied 

Natural Gas. Handbook 130, §§3.11 and 3.12 (Engine Fuels, Petroleum Products, and 

Automotive Lubricants Regulations) confirm that these requirements are for CNG, rather 

than LNG. Similar requirements and definitions are found in Handbook 44. 

During the discussions it was recognized that, although diesel and gasoline are both 

sold in gallon units, a gallon of diesel fuel has substantially more energy content than a 

gallon of gasoline. While it is convenient to use the Gasoline Gallon Equivalent unit 

when comparing the cost and fuel economy of gasoline-powered light-duty vehicles to 

equivalent natural gas vehicles, a Diesel Gallon Equivalent unit would be more useful 

for operators of medium and heavy-duty (usually diesel powered) vehicles. However, in 

1994, the NCWM working group “agreed to defer development of a “Diesel Gallon

Equivalent” until the issues related to the ‘Gasoline Gallon Equivalent’ were decided by the 

NCWM and agreed to meet again if additional work is necessary.”** The issue of the formal 

definition a Diesel Gallon Equivalent (DGE) unit has not come before NCWM from that time until 

today, although the DGE is often used in the industry, defined as 6.31 lbs of natural gas.

Need for a Definition of a “Diesel Gallon Equivalent” Unit

Today there are an increasing number of commercial vehicles using natural gas as a fuel, to 

lower emissions and Greenhouse Gases, decrease America’s use of petroleum, and lower fuel 

costs (U.S. DOE Clean Cities Alternative Fuel Price Report for April 2012 shows in Table 2 

‘Overall Average Fuel Price on Energy-Equivalent Basis’ that diesel is priced at $4.12/gal and 

CNG at $2.32/gal http://www.afdc.energy.gov/afdc/pdfs/afpr_apr_12.pdf ). 

Since the NCWM’s working group deferred development of a DGE unit in 1994, there has been 

little call by the natural gas vehicle industry for the formalization of that unit in the sale of 

Compressed Natural Gas. However the use of Liquefied Natural Gas (LNG) as a motor fuel 

has been growing and there is significant interest in using the DGE as a unit for the sale of that 

fuel.

LNG as a motor fuel is used almost exclusively by commercial vehicles, most of which view 

diesel as the conventional alternative. Using the same logic as was used for the development 

of the GGE unit, the convenience of the retail customer comparing the cost and fuel economy of 

a natural gas vehicle to a comparable conventional vehicle, it makes sense for NCWM to now 

“officially” define the DGE. 

Other than §3.12. Liquefied Natural Gas, in the Engine Fuels and Automotive Lubricants 

Regulation section of Handbook 130, we find no specific provisions in either Handbook 44 or 

Handbook 130 for the retail sale of LNG as a motor fuel. However LNG is sold in California and 

other states on a mass basis (by the pound), which allows for easy confirmation by weights and 

measures authorities. An “official” definition of the DGE as a specific mass of natural gas would 

allow states to easily move from retail sale by pound to retail sale by DGE, simplifying the sale 

process for the retail customer used to dealing with “gallons of diesel” as a fuel measure. 

Therefore, at this time we are asking for a definition of the Diesel Gallon Equivalent (and Diesel 

Liter Equivalent) units by NCWM. 

Justification of the Definition of a DGE as 6.312 Pounds of Natural Gas

Handbook 130 contains the following definitions of natural Gas as a vehicle fuel*: 

Gasoline liter equivalent (GLE). – Gasoline liter equivalent (GLE) means

0.678 kg of natural gas.

Gasoline gallon equivalent (GGE). – Gasoline gallon equivalent (GGE) means 

2.567 kg (5.660 lb) of natural gas.

As the NCWM working group recognized during its deliberations in 1993 on the Gasoline Gallon 

Equivalent unit, both gasoline and natural gas can vary in their BTU content from sample to 

sample. The working group determined the gasoline gallon (energy) equivalent based on a 

gallon of Indolene (114,118 BTU/gal – lower heating value) and a survey of 6811 natural gas 

samples nationwide with an average of 923.7 BTU/scf (lower heating value) and a density of 

0.0458172 lbs/cubic foot. This equates to 20,160.551 BTU/lb. Dividing gasoline’s 114.118 

BTU/gal by natural gas’s 20,160.551 BTU/lb gives 5.660 lbs of natural gas = 1 GGE. Similar 

calculations determined that a gasoline liter equivalent of natural gas equals 0.678 kg of natural 

gas.

Starting with 5.660 lbs of natural gas = 1 GGE and 0.678 kg of natural gas = 1 GLE, we can 

calculate the mass of natural gas necessary to make a DGE and a DLE by comparing the 

amount of energy in a gallon of diesel fuel to the amount of energy in a gallon of gasoline fuel 

and apply that ratio to scale up the masses of natural gas calculated for the GGE and GLE 

units.

Unfortunately it is no easier today than it was in 1993 to set one energy value as representative 

of a unit for all gasoline, (or diesel) fuel. EPA’s certification fuel has likely changed in energy 

content since 1993, as both gasoline and diesel fuels have been modified for improved 

emissions. 

We recommend using the most recent Department of Energy Transportation Energy Data 

Book*

, as an authoritative reference for both gasoline and diesel fuel energy values. Taking 

further surveys or basing our calculations on today’s EPA certification fuel only delays our 

action, substantially increases costs, and, in the end, provides a limited potential increase in 

accuracy based on one point in time. Table B.4 of the Transportation Energy Data Book, on the 

heat content of fuels http://cta.ornl.gov/data/tedb30/Edition30_Full_Doc.pdf lists the net energy 

of gasoline as 115,400 BTU/Gal, and diesel as 128,700 BTU/Gal. 

Therefore a Diesel Gallon Equivalent of natural gas is:

(128,700/115,400) X 5.660 = 6.312 lb (2.863 kg)

and a Diesel Liter Equivalent of natural gas is:

(128,700/115,400 X 0.678 = 0.756 kg

“Diesel Gallon Equivalent (DGE)” of Natural Gas as a Vehicular Fuel 

Clean Vehicle Education Foundation

Development of the “Gasoline Gallon Equivalent” by NCWM*

In 1993, under the auspices of the National Conference on Weights and Measures 

(NCWM), a Compressed Natural Gas (CNG) Working Group came together to 

determine the way in which CNG would be sold to the public at retail as a motor fuel. . 

The working group focused on three issues:

1. How to provide the Natural Gas Vehicle (NGV) industry a method of sale that 

would be familiar and acceptable to consumers

2. How to provide weights and measures officials a verifiable and quantifiable 

means to determine the accuracy of natural gas dispensers; and

3. How to meet these requirements with a uniform, national standard.

NCWM considered three proposals for the method of sale of CNG:

1. joules, the unit of energy measurement in SI units

2. mass 

3. the Gasoline Gallon Equivalent (GGE)

The Natural Gas Vehicle Coalition (now NGVAmerica) recommended that the Gasoline 

Gallon Equivalent be adopted as the method of sale for CNG, and that it be based on 

the energy equivalent of a gallon of gasoline. The use of the GGE was recommended 

primarily for the convenience of the retail customer comparing the cost and fuel 

economy of a natural gas vehicle to a comparable gasoline vehicle. During the 

discussion, a proposal was made to eliminate the reference to energy content of CNG 

and replace it with a fixed conversion factor based on mass, with the fixed mass of CNG 

being equal to a gallon of gasoline. Measurement of mass in the retail dispenser and

verification by W&M officials is easier and less costly than measurement of energy 

content.

Since the energy content of a unit measure of CNG (standard cubic foot - scf) and 

gasoline (gallon) vary widely depending on the sample of fuel measured, the reference 

gallon of gasoline was determined to be Indolene, the gasoline used by EPA to certify 

emissions and fuel economy, with an energy content (lower heating value) of 114,118 

BTU/gal. Work conducted by the Institute of Gas Technology and the Gas Research 

Institute (now combined into the Gas Technology Institute) surveyed 6811 samples of 

natural gas nationwide and concluded that the “average” natural gas in the US had an 

energy content (lower heating value) of 923.7 BTU/scf, and a density of 0.0458172 

lbs/cubic foot. This translates 20,160.551 BTU/lb. Dividing gasoline’s 114.118 BTU/gal 

by natural gas’s 20,160.551 BTU/lb gives 5.660 lbs of natural gas = 1 GGE. Similar 

calculations determined that a gasoline liter equivalent of natural gas equals 0.678 kg of 

natural gas.

At its 79th annual meeting in July of 1994, NCWM adopted resolutions that:

“All natural gas kept, offered or exposed for sale or sold at retail as a 

vehicle fuel shall be in terms of the gasoline liter equivalent (GLE) or 

gasoline gallon equivalent (GGE), and 

All retail natural gas dispensers shall be labeled with the conversion factor

in terms of kilograms or pounds. The label shall be permanently and 

conspicuously displayed on the face of the dispenser and shall have either 

the statement “1 Gasoline Liter Equivalent (GLE) is equal to 0.678 kg of 

Natural Gas” or “1 Gasoline Gallon Equivalent (GGE) is equal to 5.660 lbs 

of Natural Gas” according to the method of sale used.”

These statements can be found in NIST Handbook 130*, along with the definition of 

“natural gas” which seems to apply only to Compressed Natural Gas, not to Liquefied 

Natural Gas. Handbook 130, §§3.11 and 3.12 (Engine Fuels, Petroleum Products, and 

Automotive Lubricants Regulations) confirm that these requirements are for CNG, rather 

than LNG. Similar requirements and definitions are found in Handbook 44. 

During the discussions it was recognized that, although diesel and gasoline are both 

sold in gallon units, a gallon of diesel fuel has substantially more energy content than a 

gallon of gasoline. While it is convenient to use the Gasoline Gallon Equivalent unit 

when comparing the cost and fuel economy of gasoline-powered light-duty vehicles to 

equivalent natural gas vehicles, a Diesel Gallon Equivalent unit would be more useful 

for operators of medium and heavy-duty (usually diesel powered) vehicles. However, in 

1994, the NCWM working group “agreed to defer development of a “Diesel Gallon

Equivalent” until the issues related to the ‘Gasoline Gallon Equivalent’ were decided by the 

NCWM and agreed to meet again if additional work is necessary.”** The issue of the formal 

definition a Diesel Gallon Equivalent (DGE) unit has not come before NCWM from that time until 

today, although the DGE is often used in the industry, defined as 6.31 lbs of natural gas.

Need for a Definition of a “Diesel Gallon Equivalent” Unit

Today there are an increasing number of commercial vehicles using natural gas as a fuel, to 

lower emissions and Greenhouse Gases, decrease America’s use of petroleum, and lower fuel 

costs (U.S. DOE Clean Cities Alternative Fuel Price Report for April 2012 shows in Table 2 

‘Overall Average Fuel Price on Energy-Equivalent Basis’ that diesel is priced at $4.12/gal and 

CNG at $2.32/gal http://www.afdc.energy.gov/afdc/pdfs/afpr_apr_12.pdf ). 

Since the NCWM’s working group deferred development of a DGE unit in 1994, there has been 

little call by the natural gas vehicle industry for the formalization of that unit in the sale of 

Compressed Natural Gas. However the use of Liquefied Natural Gas (LNG) as a motor fuel 

has been growing and there is significant interest in using the DGE as a unit for the sale of that 

fuel.

LNG as a motor fuel is used almost exclusively by commercial vehicles, most of which view 

diesel as the conventional alternative. Using the same logic as was used for the development 

of the GGE unit, the convenience of the retail customer comparing the cost and fuel economy of 

a natural gas vehicle to a comparable conventional vehicle, it makes sense for NCWM to now 

“officially” define the DGE. 

Other than §3.12. Liquefied Natural Gas, in the Engine Fuels and Automotive Lubricants 

Regulation section of Handbook 130, we find no specific provisions in either Handbook 44 or 

Handbook 130 for the retail sale of LNG as a motor fuel. However LNG is sold in California and 

other states on a mass basis (by the pound), which allows for easy confirmation by weights and 

measures authorities. An “official” definition of the DGE as a specific mass of natural gas would 

allow states to easily move from retail sale by pound to retail sale by DGE, simplifying the sale 

process for the retail customer used to dealing with “gallons of diesel” as a fuel measure. 

Therefore, at this time we are asking for a definition of the Diesel Gallon Equivalent (and Diesel 

Liter Equivalent) units by NCWM. 

Justification of the Definition of a DGE as 6.312 Pounds of Natural Gas

Handbook 130 contains the following definitions of natural Gas as a vehicle fuel*: 

Gasoline liter equivalent (GLE). – Gasoline liter equivalent (GLE) means

0.678 kg of natural gas.

Gasoline gallon equivalent (GGE). – Gasoline gallon equivalent (GGE) means 

2.567 kg (5.660 lb) of natural gas.

Appendix A – Items 237-1 and 337-2: Background Discussion

S&T - A4 

As the NCWM working group recognized during its deliberations in 1993 on the Gasoline Gallon 

Equivalent unit, both gasoline and natural gas can vary in their BTU content from sample to 

sample. The working group determined the gasoline gallon (energy) equivalent based on a 

gallon of Indolene (114,118 BTU/gal – lower heating value) and a survey of 6811 natural gas 

samples nationwide with an average of 923.7 BTU/scf (lower heating value) and a density of 

0.0458172 lbs/cubic foot. This equates to 20,160.551 BTU/lb. Dividing gasoline’s 114.118 

BTU/gal by natural gas’s 20,160.551 BTU/lb gives 5.660 lbs of natural gas = 1 GGE. Similar 

calculations determined that a gasoline liter equivalent of natural gas equals 0.678 kg of natural 

gas.

Starting with 5.660 lbs of natural gas = 1 GGE and 0.678 kg of natural gas = 1 GLE, we can 

calculate the mass of natural gas necessary to make a DGE and a DLE by comparing the 

amount of energy in a gallon of diesel fuel to the amount of energy in a gallon of gasoline fuel 

and apply that ratio to scale up the masses of natural gas calculated for the GGE and GLE 

units.

Unfortunately it is no easier today than it was in 1993 to set one energy value as representative 

of a unit for all gasoline, (or diesel) fuel. EPA’s certification fuel has likely changed in energy 

content since 1993, as both gasoline and diesel fuels have been modified for improved 

emissions. 

We recommend using the most recent Department of Energy Transportation Energy Data 

Book*

, as an authoritative reference for both gasoline and diesel fuel energy values. Taking 

further surveys or basing our calculations on today’s EPA certification fuel only delays our 

action, substantially increases costs, and, in the end, provides a limited potential increase in 

accuracy based on one point in time. Table B.4 of the Transportation Energy Data Book, on the 

heat content of fuels http://cta.ornl.gov/data/tedb30/Edition30_Full_Doc.pdf lists the net energy 

of gasoline as 115,400 BTU/Gal, and diesel as 128,700 BTU/Gal. 

Therefore a Diesel Gallon Equivalent of natural gas is:

(128,700/115,400) X 5.660 = 6.312 lb (2.863 kg)

and a Diesel Liter Equivalent of natural gas is:

(128,700/115,400 X 0.678 = 0.756 kg

Report Cleanup:

The PDC archive is under construction on the new NCWM website. Anyone interested in seeing past reports should 

look for the report in the NCWM archives at http://www.ncwm.net/meetings/annual/archive. 

2013 Interim Topics: 

• Basic Proficiency Exams on NCWM Test Site 

The Committee heard comments in 2012 asking whether it was possible to use the NCWM test site to offer 

basic proficiency exams. At the 2013 Interim, Ms. Carol Hockert reported that NIST, OWM will be using 

the NCWM test site to administer proficiency tests, which will be used as qualifying prerequisites for 

OWM courses. The tests will be open to members and non-members alike at no fee. The first exam, which 

will be on the NCWM test site, will be a NIST Handbook 44 (Standards, Tolerances, and Other Technical 

Requirements for Weighing and Measuring Devices) self-study course exam. Contact NIST, OWM for 

further information. 

Mr. Don Onwiler confirmed that membership is not necessary to take OWM proficiency tests.

2013 Annual Meeting: Ms. Carol Hockert reported that the NIST, OWM currently requires a prerequisite 

mathematics test for applicants to their Fundamentals of Metrology training course. They intend to start 

offering that test online through the NCWM test site. This mathematics exam may also be used by weights 

and measures jurisdictions to screen job applicants. OWM also intends to provide a NIST Handbook 44 

test to compliment the NIST Handbook 44 self-study course. These tests will be free and available to all 

NCWM members and non-members alike. 

• Feedback from Registered Service Agents (RSAs) after taking Certification Exam

A small number of registered service agents (RSAs) were asked in 2012 to take the certification exams and 

provide the Committee with feedback on the suitability of the certification exams for RSAs. The 

Committee reported that it had received the following comments from the RSAs who had taken the exams:

o RSAs advised test-takers know test taking strategies

 First answer easy questions; 

 Then look up skipped questions; 

 If time allows, look up answers you thought were easy. 

o RSAs question the appropriateness of some of the fundamental questions. For example, questions 

on NCWM voting bylaws. 

 A comment was heard from the floor from one state director that nuances of the bylaws were

probably not even useful to regulatory officials at the field level, let alone RSAs. The 

Director suggested that questions should be geared toward fundamentals, general code 

applications, and field applications.

 The Committee recommends that the questions be sent back to the coordinator and SMEs for 

review as to their appropriateness. 
PDC 2013 Final Report

PDC - 4 

o RSAs thought that it took too long to get a password to take test.

 The Committee reported that password generation will be automated with the completion of 

the NCWM website upgrade.

o RSAs would like feedback for test-takers on the exam sections which they failed.

 The Committee reported that they will continue to keep that in mind if it becomes 

technologically possible to do so.

o RSAs would like to know where to find information on how to study for the exams. 

 The Committee presented a slide show to point to the curriculum hotlinks embedded in the 

course descriptions which appear at the certification site. (ncwm.net/member/tests) 

2013 Annual Meeting: The Committee reported on their response to issues raised by a small number of 

RSAs who volunteered to take the test and provide feedback:

o Corrections were made to the answer key on several questions, and all failing tests were reviewed 

to see if those questions affected the final results. Three people were notified that they had, in 

fact, passed their exams and would be issued certificates as a result of this review.

o Test passwords are now auto-generated as part of the test purchase process. T ests are free to 

NCWM members. For non-members, tests may be purchased using a credit card, a check, or a 

purchase order (P.O.). For those people wishing to purchase using a P.O., select the check option 

and then contact the NCWM office. Anyone wishing to purchase a block of tests for a group, or 

jurisdictions who wish to proctor the exams, should contact the NCWM directly instead of 

purchasing through the website.

o The Committee will continue to keep open the possibility that test section results might someday 

be reportable to test takers, but the results of specific questions will not be made available in order 

to safeguard the integrity of the tests.

o The Committee demonstrated how to access information about the tests and curriculum modules 

on the new NCWM website, as well as how to purchase the exams.

o The suggestion was made from the floor that the Committee poll jurisdictions to find out if any 

had 100 % certification of their inspectors on any exam. Of those present in the room:

 Thirteen states, and one service company reported that they had set the goal for 100 % 

certification; 

 Three states reported that they had already achieved 100 % certification in at least one 

discipline; 

 Nine states reported setting a goal of having RSAs certified as part of their permitting 

process; 

 No state reported that they had already implemented a requirement that RSAs have 

professional certification.

o A question was asked about what time commitment is asked of someone volunteering to be a 

subject matter expert (SME). The answer was approximately 20 hours over six to eight months. It 

is not necessary to be a trainer or a manager to be an SME. This is an excellent way to develop 

senior investigators who may become trainers in the future. This is also an opportunity where 

retirees can contribute their skills and experience. Industry participation is encouraged. 
PDC 2013 Final Report

PDC - 5 

o In response to a question from the floor, the Committee reported that there is no conflict of interest 

if trainers wish to participate as SME because they are only exposed to a small portion of the test 

question bank, and their agreement with the NCWM is that the questions they see are the property 

of the NCWM and may not be used in their own training programs.

• Status of Current tests

Current tests – RMFD, Small Capacity Retail Scales, Basic Package Checking.

The Committee reported that exam statistics show steady improvement over time, indicating that much of 

the problem with passing the tests has to do with a need to acclimate to on-line testing.

The Committee also wanted to assure members that SMEs will not compromise their ability to be trainers 

as no SME will be allowed to have access to more than 25 % of the questions. 

Mr. Onwiler made a comment that this restriction on access to the test questions was an important part of 

maintaining the integrity of the exam process as the certification program moves toward formal 

accreditation. Eventually exam questions may need to be copyrighted. SMEs should note that they should 

modify test questions before submitting them to the certification coordinator if they wish to continue to use 

those questions in their own exams.

• Certification Coordinator Reported on Exam Question Pass/Fail Statistics

The Certification Coordinator reviewed the exam question statistics for each exam:

o Statistics indicate that the questions and time required to answer them are generally appropriate.

o He explained the significance of differentiating questions that took a long time to answer and had 

low passing rates among those who failed the test, but had high passing rates among those who 

passed the tests. These questions separate those who really know their stuff from those who do 

not.

o Exam statistics also indicated that most test-takers had more difficulty with general questions and 

fundamental questions than they did with device specific questions. This indicates that there is a 

training imbalance between general principles and device specifics. H e noted that part one of 

every exam covers the general code and fundamental considerations.

o There are questions in the small capacity scale exam and the package checking exam which will 

be reviewed by the SMEs to check appropriateness and wording.

An industry representative wanted to know how industry could help improve the exams. The Committee 

responded:

o Take the exams and give the Committee feedback; 

o Participate as SMEs in developing tests; 

o Be a resource to provide training materials; and

o Help with instructor improvement, particularly relating to training Registered Service Agents 

(RSAs). 
PDC 2013 Final Report

410-2 I Training

The Committee recommended that a new item dealing with training be inserted and subsequent item numbering be 

adjusted. The purpose of this item is to share information gleaned from the certification test statistics regarding 

broad training needs, and to serve as a link to various training materials on the web. Eventually, it can become a 

home for the training material program currently under development by the NCWM Board of Directors.

The Committee reported that the Board of Directors is assembling a new work group to be headed by Mr. Michael 

Cleary, former Director of the California Division of Measurement Standards. The function of the work group will 

be to develop guidance on the scope of training for weights and measures officials and will report to the PDC. 

Anyone interested in serving on this work group should contact the NCWM Board of Directors.

410-3 I Instructor Improvement

Report Cleanup:

2013 Interim Meeting: The Committee agreed to move the historical data in the current item to Appendix C, with 

the intention of moving it into the Committee archives at the 2014 Interim. Moving forward, historical information 

will be archived and items will contain only current action items.

Current Items:

The Committee called on Ms. Hockert to discuss NIST, OWM’s new regional trainer program. Ms. Hockert

reported that NIST, OWM is looking for a way to increase the number of trainers available to teach OWM courses. 

OWM will be hosting a Train-the-Trainer course in April 2013 with the intention of developing a pool of weights & 

measures officials capable of offering NIST, OWM training at the regional level. The training is free, and OWM 

asks for a minimum commitment from each participant of leading one to two training courses with a NIST, OWM 

trainer in the subsequent year. Expenses involved with teaching the course(s) would be covered by NCWM through 

an OWM grant. 

2013 Annual Meeting: Ms. Hockert reported that the NIST, OWM Train-the-Trainer program had already trained 

20 weights and measures officials from 17 states on techniques for training adult learners. Nine NIST courses will 

be taking place between July and November, at which those people will be assisting and observing. The OWM is 

looking to increase the number of people who receive that basic training, and also to add continuing training for 

those people who have taken the first course. The ultimate goal is to have many people around the country capable 

of leading training on NIST technical courses. In response to questions from the PDC, the Associate Membership 

Committee clarified that under their current bylaws funds are available to bring trainers to jurisdictions but not to 

send individuals to training – even to courses meant to train trainers. 

410-4 I Recommended Topics for Conference Training

Source: 

Carryover Item 401-5 (This item originated from the Committee and first appeared on its agenda in 2003.)

Background/Discussion: 

The Board of Directors has charged the Committee with recommending appropriate topics for the technical sessions 

at future Annual Meetings. The Board of Directors asked the PDC to review and prioritize possible presentations 

and submit those to NCWM Chairman. The Chairman will coordinate with NCWM staff to secure presenters and 

schedule the sessions.

The Committee acknowledged the continued interest in having a presentation on Making Sense of Electronic 

Receipts and is seeking assistance in identifying a suitable presenter on the topic. A comment was heard from the 

floor that Price Posting on Retail Motor Fuel Devices should be added to the list so that the new changes can be 

explained.

The Committee asks for suggestions for safety articles that people would like to see in future newsletters and/or 

safety issues that need to be addressed immediately. T he PDC reminds regional associations to check the 

submission deadlines for their upcoming article assignments. Send completed articles to NCWM headquarters by 

the submission deadline.

The Committee supports the recommendation made at the 2012 NCWM Annual Meeting that the safety articles in 

the NCWM Newsletters be extracted and compiled in one central location on the NCWM website.

An industry representative commented that this item is being underutilized and he urges everyone to give more 

attention to this item in the future. A state official made the suggestion that the Committee develop an anonymous 

form for people to report not only incidents but also near-misses.

complete to ensure that interested parties can easily find and utilize the materials. The three main sections of 

material include:

1. Committee Active Working Documents – includes active documents describing the developing 

professional certification program, the curriculum plan, Body of Knowledge (BOK) documents currently 

under development and open for comment (i.e., prior to release of a certification exam, program guidelines 

and administrative procedures); 

2. Professional Certification Documents – includes the certification exam shopping page, exam 

descriptions, related BOK documents, aids to taking the certification exams; 

3. Committee Archives – includes archive of historical documents that provide insight into the evolution of 

the Committee since inception and evolution of the Professional Certification Program. Interested parties 

should also refer to meeting archives at www.ncwm.net/meetings/annual/archive. 

In addition, the Committee believes it is vital to move forward with a more formal set of administrative procedures 

for running a credible certification program. The Committee will make efforts to continue the work of Mr. Sikula 

(New York) at the request of the Board of Directors, to document our procedures following International 

Standardization Organization (ISO) 17024 Guidelines for Certification Bodies. The Board of Directors is also 

considering alternative ANSI standards. The Committee will be working with the Board of Directors on this project. 

NCWM management has ultimate responsibility for contracting with the testing service, policy issues, and staffing 

(both headquarters staff and the Certification Coordinator).

Carryover Item 401-1 (This item originated from the Committee and first appeared on its Agenda in 2003 and has 

undergone continuing development.) The numbering change reflects harmonization in all NCWM reports. Copies 

of reports from recent years are also available on the website under Interim and Annual Meeting archives pages. 

Background/Discussion: 

It is important that users of the Professional Certification Program understand how the pieces fit together and form a 

coherent system. To illustrate the relationships the Committee can describe the system as a triangle of 

interdependent parts (see diagram below). T he standards come in the form of goals with measureable learning 

objectives. The education part involves training provided to help the candidate reach the desired level of proficiency 

for each of the learning objectives. The certification involves an assessment of proficiency that measures whether or 

not the objectives have been met.

Certification Triangle

The Committee has until now focused attention on the standards and the certification pieces in the triangle as 

illustrated in the following flowcharts.

Standard Subsystem

Certification Subsystem

The Committee has described this work in a number of documents. In those documents the Committee is using 

terminology consistent with current usage in the education and certification field. The following important terms 

will be used throughout the Committee’s work on the subject. 

Body of Knowledge (BOK) – refers broadly to the knowledge and skills required to function as a weights and 

measures professional. The term may refer broadly to the entire scope of knowledge and skills required within the 

profession or in a more directed manner to any selected subset for which the particular person is responsible. The 

BOK describes what you expect the weights and measures professional to achieve as opposed to how he/she will 

achieve it. To make the BOK more manageable in administration of the Professional Certification Program, it will 

be subdivided into modules in a tree-like structure moving from general knowledge and skills to more specific. 

Module – refers to a g roup of related subject materials within the BOK. T he module contains the articulated 

learning objectives for the subject area. E ach module is considered a s ingle, self-contained course of study. 

However, a broader course may span multiple modules and specific training may include only part of a module or 

parts of multiple modules. The PDC has created a s tandard format to create modules for the Professional 

Certification Program. The Committee has also created the Curriculum Outline and work plans to help manage the 

work activities within the program to create the many modules necessary to cover the entire profession. 
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B3 

Learning Objective – refers to the articulation of expectations of performance in measureable terms. Learning 

objectives are stated using active terms to be precise and measureable. There are two types of learning objectives, a 

terminal objective and an enabling objective. Terminal objectives state broadly the expectation of performance. 

The enabling objectives state the specific parts or steps required to demonstrate competence. T he PDC has 

developed a guide to writing the learning objectives for both terminal and enabling which include the active verbs 

associated with the cognitive levels in Bloom’s Taxonomy. In training, the instructor will typically choose learning 

activities to explore each of the enabling objectives in an attempt to reach the terminal objective. In assessment, the 

questions will typically test for competence in each of the enabling objectives to demonstrate that the terminal 

objectives have been met.

Professional Certification – refers to verification of proficiency relative to all or part of the BOK for the profession 

as designated by the PDC for inclusion in a certification exam. The selected BOK includes all or part of specific 

modules and is documented in an exam description. E ach of the modules, or combinations, is given a specific 

weighting in the design of the exam. After obtaining a passing score on the exam, the candidate is issued a 

certificate stating he/she has met the competency standard. 

Curriculum – refers to the list of modules that are used to document the BOK (see Appendix A).

Bloom’s Taxonomy – refers to a classification of levels of cognitive leaning widely used in the field of education. 

The levels are knowledge, understanding, application, analysis, integration, and evaluation. The active verbs used in 

the articulation of learning objectives define the cognitive level. In training, the learning activities are matched to 

the cognitive level. In assessment, the form of the question is also matched to the cognitive level. T he use of 

Bloom’s Taxonomy is described in detail in the Body of Knowledge Model document.

The PDC has prepared program documents that are available on NCWM website. 

• The Curriculum Outline, which breaks the profession of weights and measures into component parts called 

modules.

• The Body of Knowledge Model, which explains how to create modules to document the learning 

objectives.

• The Modules developed thus far.

• The Certifications developed thus far. 

Results of the Retail Motor Fuel Dispensing Systems exam indicate it will be very important as the program moves 

forward that trainers integrate the learning objectives into their materials and design courses in such a way that 

candidates will achieve the desired levels of learning. See Item 401-2 Instructor Improvement. 

2011 NCWM Interim Meeting: T he Committee addressed the need to build partnerships between the states, 

National Institute of Standards and Technology (NIST), Office of Weights and Measures (OWM), and NCWM. 

Each group has roles in relation to the Certification Triangle as shown in the diagram below.

2012 NCWM Interim Meeting: The Committee received a comment from NIST, OWM that there is a need to 

provide an assessment tool to measure basic competence in fundamental subject areas such as NIST Handbook 44. 

They hope to partner with NCWM to administer those assessments using NCWM testing service. This would assure 

that participants at NIST, OWM sponsored training possess basic levels of proficiency in prerequisite materials so 

that instructors can deliver the primary material rather than spend time bringing all students up to the prerequisite 

level. 

The Committee agrees and believes this fits with ongoing efforts to create a BOK and an exam to assess competence 

in mathematics for the entry level inspector. This could also be a useful tool to any jurisdiction offering training in 

these basic areas. The Committee will call these baseline competency examinations defined as:

Baseline Competency Examination - refers to verification of proficiency relative to one of the basic modules in the 

BOK for the profession. After obtaining a passing score on the exam, the candidate is issued a certificate stating 

he/she has met the competency standard. 

The initial modules under consideration for the basic competency examinations are:

• Module XX. Weights and Measures Core Mathematics 

• Module 4.2. NIST Handbook 44 – Introduction to Device Control

• Module 4.3. Weighing Systems – General

• Module 4.4. Dynamic Volume Measuring Systems – General
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B5 

The BOK document for the Core Mathematics module has been drafted and will be posted on the website and 

appears in Appendix B.

The professional certifications currently developed (or in development) are:

• Retail Motor Fuel Dispensing Systems (Available)

• Package Checking Basic (Available)

• Small Capacity Weighing Systems Class III (Available) and

• Vehicle Tank Meters (In Development)

The Committee reported that 18 Subject Matter Expert (SME) volunteers are working on the basic package checking 

exam and 20 SME volunteers are working on the small capacity scale exam. Those exams are nearing completion. 

Invitations will be sent shortly to NCWM members to solicit SME volunteers to work on the vehicle tank meter 

exam. T he Committee noted that SME’s are the backbone of the program but also that they have competing 

priorities. One consideration is the idea of doing this work using web meetings, one to brief and train SMEs at the 

start of a project and one at the end to resolve any remaining issues with complex questions on the exam. The idea 

is to minimize the time commitment of our SME volunteers while maintaining high quality in our exams. 

The PDC conducted a survey in November 2011 to evaluate priorities for future exam development, appropriate 

range of device capacities to include in the medium or large capacity scale modules, request feedback from people 

who had taken the Retail Motor Fuel Dispensing Systems Exam, appropriateness of our examinations for Registered 

Service Agents (RSAs), and potential problems in standardizing exams on the current NCWM standards.

The Committee received 134 responses covering 25 states, approximately 80 % weights and measures and 20 % 

industry. Based on the responses the Committee has selected the following subjects for priority development and 

will be requesting that the Board of Directors extend the Certification Coordinator’s contract for these new projects: 

• Medium Capacity Scales 

• Large Capacity Scales III and IIIL

• Liquefied Petroleum Gas (LPG) and Anhydrous Ammonia Liquid

• Price Verification

Survey questions on the Retail Motor Fuel Dispensing Systems Exam indicated that the majority were somewhat or 

very satisfied with the test taking experience, that the exam questions were appropriate to the basic level inspector, 

that the questions were straight forward and clearly written, and that they were able to finish in the allotted time. 

The only problems identified seemed to be related to computer connections and loading of graphics. NCWM staff 

worked with the testing service to mitigate these issues. 

On the issue of using NCWM professional certifications for RSAs, the majority responded with interest in this area. 

The Committee worked with NCWM staff to solicit RSA volunteers to take the exam for free in order to obtain 

feedback. Volunteers who passed the exam would receive the formal certificate if they were members or if they pay 

the $75 testing fee as non-members. Four RSAs took the exam thus far and others are scheduled to take it. The 

Committee will gather additional data, evaluate the results and report at the Annual Meeting. 

2012 NCWM Interim Meeting: Several state officials questioned the appropriateness of charging these volunteers 

for the certificate if they are non-members. They noted that the service agents invested considerable time in taking 

the exam so that those who passed could have been rewarded with a waiver of the fee. M r. Onwiler, NCWM 

Executive Director, reported that the exam fee structure is controlled by the Board of Directors. The exam fee is 

waived for members as a way to improve membership value. The exam has always been available to service agents, 
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B6 

but this was a means of acquiring volunteers for data collection without making them pay fees as non-members. 

The Committee verified that participants were advised of the conditions when the volunteers were contacted. The 

Western Weights and Measures Association (WWMA) made a p roposal in 2011 that NCWM consider a t iered 

membership that would allow for a group rate category or reduced fees for non-members presently employed in a 

weights and measures related field wishing only to take the examinations. The Committee will ask the Board of 

Directors to consider these comments.

On the subject of the use of the current NCWM standard as the basis of all exams, the feedback from the survey 

clearly indicated that this should not be a problem for most jurisdictions. Therefore, the Committee will develop all 

exams based on the current editions of NCWM standards. 

Officials had concerns about preparing their workforce for taking the Retail Motor Fuel Dispensing Systems Exam. 

As the PDC proceeds in offering other certifications, the Committee wants jurisdictions and industry to feel 

supported and confident that the training they provide for their workforce will be comprehensive and will prepare 

their people to take the certification exams without providing them with the exam questions. T he Committee 

therefore recommends better communication so they understand what tools are available to help them create their 

own comprehensive training programs. The critical viewpoint is that a professional has to be prepared to perform 

the job and not just prepared to take the exam. This is the age old question of training to the learning objectives (the 

BOK) or training to the exam. The Committee strongly believes that training has to focus on the BOK and not on 

the exam questions. 

2012 NCWM Annual Meeting: The Committee met with the Board of Directors to provide an update on progress 

and agree on priorities. The Certification Coordinator reported that two additional question banks for small capacity 

scales and package checking had passed the technical review and were submitted to NCWM Headquarters. He also 

reported that SME volunteers are now working on the vehicle tank meter exam, and that he is expecting to start the 

search for SME volunteers for the medium and large capacity scale exams shortly after the Annual Meeting. NCWM 

Executive Director Don Onwiler reported that there has been a slight glitch in the system that must be corrected 

before two new the exams can be opened for use. This involves making sure that Headquarters controls the 

individual’s access to exams. Each candidate gets access to initially take the exam and then can get a retest if they 

fail. The original process had given the candidate access to all exams using the same credentials. As soon as this is 

corrected they will broadcast the availability of the two new exams.

The idea of accrediting the certification program was discussed. The Executive Director reported that he had been 

discussing the idea with the Institute for Credentialing Excellence (ICE) to see what parts of our program might be 

potential stumbling blocks. One area involves the SME’s who develop and vet the test questions. Our problem is 

that our SMEs are virtually all trainers within their jurisdictions and the vetting and training functions need to be 

separated. One possible avenue that we are pursuing is to restrict the access each SME has to the exam bank by only 

allowing them to review a part (~1⁄4) of the test bank. The advice also suggested that SMEs be asked to sign over 

rights to the test questions and that NCWM seek to copyright its exams. The Committee and the Coordinator will 

continue to work with the Executive Director toward the goal of meeting the accreditation standards and both the 

Coordinator and Headquarters will work on documenting procedures as a n ecessary step in that process. The 

Executive Director will continue to seek advice towards this long term project from ICE.

The Executive Director provided the Committee and the Board of Directors with following statistics on the Retail 

Motor Fuel Exam.

The Committee and the Board of Directors agreed that priorities will remain on the Professional Certifications. The 

Committee will not be pursuing the competency exams. This will help focus efforts to get the exams out based on 

priorities established by the survey the Committee conducted.

The Committee understands that the SMEs are the critical part of our certification program. The Committee wants 

to recognize those that are contributing and also encourage others to volunteer on future projects (i.e., the medium 

and large capacity scale exams that will start soon). To this end, the Committee wants to express gratitude by giving 

recognition to the following who contributed to the package checking and small capacity scale exams.

The Committee heard testimony from a number of individuals during the open hearings and appreciates the 

comments. In particular, the Committee is very pleased that states are starting to find ways to integrate our 

standards and the certifications in their programs. One state reported their efforts to mandate in regulation that 

RSAs get NCWM certification to demonstrate competence. Another is giving CEUs to county officials who obtain 

NCWM Certification. Others are using the exam results to evaluate their training efforts. One jurisdiction is using 

NCWM certifications in labor relations to demonstrate that retention and promotion decisions are being based on an

unbiased third party assessment. The CWMA is considering whether it might be possible to use the NCWM exam in 

their reciprocal testing program for RSAs. 

One state director reported that he had his entire staff take the RMFD exam. He provided some valuable feedback 

that the Committee and the Coordinator will consider. One involved making clear which version of the handbooks 

is being used in the exams. He also reported that candidates taking the exam wanted to learn about which questions 

they got wrong. He also wanted the Committee to look at extending the Certification Program to accredit the overall 

weights and measures program.

The Committee understands the concern about the wrong answers, but maintaining integrity of the test precludes us 

from giving that kind of specific feedback on the exam. At the end of the exam, the candidate is provided with the 

pass/fail on each segment of the exam and the final score. The candidate is also provided with the option of 

designating the e-mail address where the results will be sent. Thus, the results could go to a Supervisor or the 

Director. The Committee is considering avenues to provide feedback that will help states identify potential 

weaknesses in their training programs. Again, the Committee wants to divert the focus from the test back to 

ensuring mastery of the learning objectives in the BOK. To that end, the Committee is considering providing 

general statistics on each part of the exam so that a jurisdiction/company could compare their staff’s results with the 

composite of all those who took the exam. There is a further fear that providing detailed feedback on specific 

learning objectives where exam results showed low scoring would then divert the focus from the broad objectives of 

the BOK.

2012 CWMA Interim Meeting: T here was general support for removing much of the content in this item and 

making it reference material on the NCWM website. There was a question regarding how NCWM assesses exam 

difficulty and a suggestion to look at professional certification programs for other industries to see what the passing 

rates are and what they use to know if the exams are at the appropriate difficulty level. There were several 

suggestions to improve the exam process, including a flag button on each test question that test takers could select to 

notify that a specific question was problematic. Another was to provide a direct link at the end of the test to a 

survey site or other site for immediate feedback on the test. Another suggestion was to disclose to test takers which 

areas of NIST Handbook 44 they should study based on their results, without being told the actual questions that 

were incorrect. This would maintain the integrity of the test while providing guidance to the test taker.

2012 WWMA Annual Meeting: T he WWMA PDC chair presented a P owerPoint presentation reviewing the 

Professional Certification Program (PCP) entitled “Using the NCWM Program” during the open hearings. O ne 

comment/question was received during the open hearings regarding the time limit to take an exam after an 

individual has registered and received their passcode. The Committee, in conversation with the NCWM Executive 

Director by telephone, confirmed that there is no time limit for initial log in or between taking the first and second 

exam. Furthermore, if a NCWM member fails the second exam, he or she can reapply and retest until they pass the 

exam, free of charge. The Committee discussed the draft FAQ sheet developed by Ross Andersen and recognized 

that it is a good start and is in need of further development. The Committee is willing to assist with enhancing and 

clarifying this document. The Committee discussed the exam result data compiled on the three exams to date. The 

RMFD exam has been available since 2010. The Package Checking Basic and Small Capacity Scales Class III have 

been available since August 2012. The Committee recognized the likelihood that the pass/fail rate on the exams to 

date may not reflect the difficulty of the exam since many may be taking the exams to familiarize themselves with 

the exam process, not necessarily for obtaining the certificate. The Committee discussed accreditation of the PCP, 

the benefits to both industry and regulatory individuals, and the issue created by crossover between persons serving 

as both Subject Matter Experts (SMEs) and trainers. The Committee discussed the difference between certification 

to demonstrate basic competency, accreditation, and licensing with continuing education requirements. T he 

Committee believes that for the PCP to be accredited more information is needed about the specific accreditation 

requirements so the NCWM Professional Development Committee (NCWM PDC) can efficiently and correctly 

design the Program. The Committee encouraged the WWMA audience to take one or more of the three exams that 

are available. The Committee discussed the need for volunteer SMEs, exam results data and feedback on the exam 

taking experience, to assist the NCWM PDC in the continuous improvement of existing exams, and further 

development of future exams. F eedback can be submitted to the NCWM PDC through NCWM via e-mail 

to info@ncwm.net or call (402) 434-4880. The concept of free exams or a “rollback” in pricing for a period of time 

was discussed. There may be jurisdictions, business organizations, or other entities that desire to take the exams, but

find the cost of membership is prohibitive. The Committee believed there might need to be an initial incentive to 

encourage participation. The Committee recommends the following:

• NCWM survey jurisdictions to find out the number of Registered Service Agents (RSAs) within the 

jurisdiction, whether these jurisdictions require the RSA to pass an examination, and what fees and 

timelines are associated with these requirements. Determining the number of jurisdictions that require 

licensing and the content of their examinations (e.g., regulatory vs. technical requirements) would allow the 

NCWM PDC to evaluate the appropriateness of administering the same exams for RSAs or development of 

separate exams particular to RSAs. The jurisdictions using these written exams in their training programs 

could do so in conjunction with a field component to certify inspectors and RSAs. 

• NCWM Executive Director continue research into the accreditation requirements and recommend the 

appropriate accreditation body for the PCP; weights and measures jurisdictions and industry organizations 

that may require certification recognize the value and credibility provided through formal accreditation.

• NCWM PDC continues its work refining the PCP FAQ Sheet. The WWMA PDC Committee is willing to 

assist with enhancing and clarifying this document. The PCP FAQ Sheet is a valuable tool for new exam 

takers.

• NCWM PDC consider implementing a policy of offering newly introduced exams at a reduced price for a 

fixed period of time (e.g., $30 per exam for six months, providing the exam taker agree to provide feedback 

on the exam contents and exam taking experience before receiving their certificate). NCWM needs to 

encourage the widest possible participation in the early stages of PCP development. To bring the PCP to 

full program fruition, offering incentives to exam takers may assist the NCWM in reaching its goals.

One jurisdiction indicated that they would begin using the examinations as part of their annual performance plans 

and performance evaluations for their staff. T he Committee realized that the PCP was originally designed for 

weights and measures officials, but discussed whether the exams should be modified for RSA to put more emphasis 

on proper calibrations, sealing, etc.

Carryover Item 401-3 (This item originated from the Committee and first appeared on its agenda in 2003.)

Background/Discussion: 

Prior to the 2010 Annual Meeting, Ms. Georgia Harris, NIST, OWM provided the Committee with reference 

material on teaching methods and assessment of training success. Distilling the essence of these materials, the 

Committee believes that instructors need training in more than just the technical material; they need training in 

setting the learning objectives, developing the training materials with those objectives in mind, selecting training 

methods that incorporate adult learning styles, and evaluating the effectiveness of their training.

Education Subsystem

The chart below covers three levels of learning objectives and relates them to (1) the training activities most likely to 

be successful and (2) the best methods for assessing the success of the training. The curriculum segments state the 

learning objectives using verbs similar to those in the bottom row of the table. T hese drive both the training 

activities required to promote adult learning and the assessment tools appropriate to measure success at that level.

webpages. The importance of pre-training analysis and post-training evaluation cannot be overestimated. Failure to 

include these steps often leads to failure of training efforts.

Professional Certification Program

Systems Approach to Training Evaluation

The Committee is calling on the states and other training developers to implement the Analysis, Design, 

Development, Implementation, and Evaluation (ADDIE) model in their training preparations and post training 

evaluation. E veryone needs to participate in the development of new BOK modules and then encourage their 

trainers to use existing BOK modules in their training plans.

The Committee encourages members to also look at the presentation on A Complete Training Program prepared by 

Ms. Carol, Hockert, NIST, OWM. The presentation outlines ways to develop training programs and improve 

instruction of weights and measures material. Contact Ms. Hockert for a copy.

2012 NCWM Interim Meeting: Advisors from NIST, OWM, reported that they are using NCWM BOK in preparing 

new training initiatives. They are stressing adult learning techniques, particularly focusing on the use of hands-on 

training as the most popular and effective training tool. This ties in closely with the new baseline competency 

exams discussed in Item 410-1. NIST, OWM is using these exams to ensure students in NIST sponsored training 

courses are competent in prerequisite course materials prior to taking training. They reported that they are already 

drafting questions for the baseline competency exams. They see significant efficiencies in using NCWM testing 

services for this purpose since they are already in place. 

Ms. Hockert, NIST, OWM, recommended a basic math prerequisite for persons taking Metrology or other related 

weights and measures courses sponsored by NIST. The math exam would allow trainees to demonstrate entry level 

math skills and make the training process more efficient and effective. O ne official discussed the California 

licensing requirement of a college degree which requires a certain number of math courses and asked if this would 

satisfy the need for the math prerequisite. S everal California officials expressed concern about the Professional 

Certification Program replacing existing state licensing programs, and if adopted, it might require amendment of 

existing state statutes. B ecause math competency is an essential skill for weights and measures work, the 

Committee recommends that the PDC include in its scope the development of an exam to demonstrate basic math 

competency before taking the Fundamentals of Metrology or other training courses at NIST.

2011 SWMA Annual Meeting: I t was stated that we should consider training state trainers on adult learning 

techniques as well as subject matter. No further recommendations were made.

2012 NCWM Annual Meeting: T he Committee stressed instructor improvement. The Committee reviewed the 

importance of using the NCWM learning objectives and the ADDIE model in training. This stresses the importance 

of training to the goals in the BOK and not training to pass the test. If the training is appropriate and has been 

delivered effectively, the employee should have no problem passing a fair exam. The end is not a certificate on the 

wall, but rather a competent inspector. In other words,

JOB SUCCESS = EXAM SUCCESS

Ms. Hockert stressed that good training requires a partnership between the trainee, trainer, and the supervisor. The 

Committee agrees that buy-in from all levels is critical to training success.

2012 CWMA Interim Meeting: T he Committee recommended archiving most of the content in this item to the 

NCWM website as reference material.

2012 WWMA Annual Meeting: T he Committee noted that it is in the best interest of NIST and NCWM that 

regional training efforts are of the highest quality and uniform throughout the United States. The Committee 

recommends the following:

• Regional trainers be selected as per the process agreed upon between NIST and NCWM;

• Regional trainers receive courses on adult learning techniques and converting technical information into 

training materials; 

• Regional trainers be afforded the opportunity to shadow NIST trainers as they perform training in 

individual jurisdictions; and

• The use of funds from the Associate Membership Committee or the NIST Training Initiative Grant be 

made available for this purpose.

2012 NEWMA Interim Meeting: Members expressed interest in NIST Train-the-Trainer classes. A demonstration 

was provided on how to access materials for taking the Professional Certification Exams and then for taking the 

exams. The Committee encouraged those in attendance to seek certification of their inspectors.

Carryover Item 401-1 (This item originated from the Committee and first appeared on its Agenda in 2003 and has 

undergone continuing development.) The numbering change reflects harmonization in all NCWM reports. Copies 

of reports from recent years are also available on the website under Interim and Annual Meeting archives pages. 

Background/Discussion: 

It is important that users of the Professional Certification Program understand how the pieces fit together and form a 

coherent system. To illustrate the relationships the Committee can describe the system as a triangle of 

interdependent parts (see diagram below). T he standards come in the form of goals with measureable learning 

objectives. The education part involves training provided to help the candidate reach the desired level of proficiency 

for each of the learning objectives. The certification involves an assessment of proficiency that measures whether or 

not the objectives have been met.

Certification Triangle

The Committee has until now focused attention on the standards and the certification pieces in the triangle as 

illustrated in the following flowcharts.

Standard Subsystem

Certification Subsystem

The Committee has described this work in a number of documents. In those documents the Committee is using 

terminology consistent with current usage in the education and certification field. The following important terms 

will be used throughout the Committee’s work on the subject. 

Body of Knowledge (BOK) – refers broadly to the knowledge and skills required to function as a weights and 

measures professional. The term may refer broadly to the entire scope of knowledge and skills required within the 

profession or in a more directed manner to any selected subset for which the particular person is responsible. The 

BOK describes what you expect the weights and measures professional to achieve as opposed to how he/she will 

achieve it. To make the BOK more manageable in administration of the Professional Certification Program, it will 

be subdivided into modules in a tree-like structure moving from general knowledge and skills to more specific. 

Module – refers to a g roup of related subject materials within the BOK. T he module contains the articulated 

learning objectives for the subject area. E ach module is considered a s ingle, self-contained course of study. 

However, a broader course may span multiple modules and specific training may include only part of a module or 

parts of multiple modules. The PDC has created a s tandard format to create modules for the Professional 

Certification Program. The Committee has also created the Curriculum Outline and work plans to help manage the 

work activities within the program to create the many modules necessary to cover the entire profession. 
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B3 

Learning Objective – refers to the articulation of expectations of performance in measureable terms. Learning 

objectives are stated using active terms to be precise and measureable. There are two types of learning objectives, a 

terminal objective and an enabling objective. Terminal objectives state broadly the expectation of performance. 

The enabling objectives state the specific parts or steps required to demonstrate competence. T he PDC has 

developed a guide to writing the learning objectives for both terminal and enabling which include the active verbs 

associated with the cognitive levels in Bloom’s Taxonomy. In training, the instructor will typically choose learning 

activities to explore each of the enabling objectives in an attempt to reach the terminal objective. In assessment, the 

questions will typically test for competence in each of the enabling objectives to demonstrate that the terminal 

objectives have been met.

Professional Certification – refers to verification of proficiency relative to all or part of the BOK for the profession 

as designated by the PDC for inclusion in a certification exam. The selected BOK includes all or part of specific 

modules and is documented in an exam description. E ach of the modules, or combinations, is given a specific 

weighting in the design of the exam. After obtaining a passing score on the exam, the candidate is issued a 

certificate stating he/she has met the competency standard. 

Curriculum – refers to the list of modules that are used to document the BOK (see Appendix A).

Bloom’s Taxonomy – refers to a classification of levels of cognitive leaning widely used in the field of education. 

The levels are knowledge, understanding, application, analysis, integration, and evaluation. The active verbs used in 

the articulation of learning objectives define the cognitive level. In training, the learning activities are matched to 

the cognitive level. In assessment, the form of the question is also matched to the cognitive level. T he use of 

Bloom’s Taxonomy is described in detail in the Body of Knowledge Model document.

The PDC has prepared program documents that are available on NCWM website. 

• The Curriculum Outline, which breaks the profession of weights and measures into component parts called 

modules.

• The Body of Knowledge Model, which explains how to create modules to document the learning 

objectives.

• The Modules developed thus far.

• The Certifications developed thus far. 

Results of the Retail Motor Fuel Dispensing Systems exam indicate it will be very important as the program moves 

forward that trainers integrate the learning objectives into their materials and design courses in such a way that 

candidates will achieve the desired levels of learning. See Item 401-2 Instructor Improvement. 

2011 NCWM Interim Meeting: T he Committee addressed the need to build partnerships between the states, 

National Institute of Standards and Technology (NIST), Office of Weights and Measures (OWM), and NCWM. 

Each group has roles in relation to the Certification Triangle as shown in the diagram below.

2012 NCWM Interim Meeting: The Committee received a comment from NIST, OWM that there is a need to 

provide an assessment tool to measure basic competence in fundamental subject areas such as NIST Handbook 44. 

They hope to partner with NCWM to administer those assessments using NCWM testing service. This would assure 

that participants at NIST, OWM sponsored training possess basic levels of proficiency in prerequisite materials so 

that instructors can deliver the primary material rather than spend time bringing all students up to the prerequisite 

level. 

The Committee agrees and believes this fits with ongoing efforts to create a BOK and an exam to assess competence 

in mathematics for the entry level inspector. This could also be a useful tool to any jurisdiction offering training in 

these basic areas. The Committee will call these baseline competency examinations defined as:

Baseline Competency Examination - refers to verification of proficiency relative to one of the basic modules in the 

BOK for the profession. After obtaining a passing score on the exam, the candidate is issued a certificate stating 

he/she has met the competency standard. 

The initial modules under consideration for the basic competency examinations are:

• Module XX. Weights and Measures Core Mathematics 

• Module 4.2. NIST Handbook 44 – Introduction to Device Control

• Module 4.3. Weighing Systems – General

• Module 4.4. Dynamic Volume Measuring Systems – General
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B5 

The BOK document for the Core Mathematics module has been drafted and will be posted on the website and 

appears in Appendix B.

The professional certifications currently developed (or in development) are:

• Retail Motor Fuel Dispensing Systems (Available)

• Package Checking Basic (Available)

• Small Capacity Weighing Systems Class III (Available) and

• Vehicle Tank Meters (In Development)

The Committee reported that 18 Subject Matter Expert (SME) volunteers are working on the basic package checking 

exam and 20 SME volunteers are working on the small capacity scale exam. Those exams are nearing completion. 

Invitations will be sent shortly to NCWM members to solicit SME volunteers to work on the vehicle tank meter 

exam. T he Committee noted that SME’s are the backbone of the program but also that they have competing 

priorities. One consideration is the idea of doing this work using web meetings, one to brief and train SMEs at the 

start of a project and one at the end to resolve any remaining issues with complex questions on the exam. The idea 

is to minimize the time commitment of our SME volunteers while maintaining high quality in our exams. 

The PDC conducted a survey in November 2011 to evaluate priorities for future exam development, appropriate 

range of device capacities to include in the medium or large capacity scale modules, request feedback from people 

who had taken the Retail Motor Fuel Dispensing Systems Exam, appropriateness of our examinations for Registered 

Service Agents (RSAs), and potential problems in standardizing exams on the current NCWM standards.

The Committee received 134 responses covering 25 states, approximately 80 % weights and measures and 20 % 

industry. Based on the responses the Committee has selected the following subjects for priority development and 

will be requesting that the Board of Directors extend the Certification Coordinator’s contract for these new projects: 

• Medium Capacity Scales 

• Large Capacity Scales III and IIIL

• Liquefied Petroleum Gas (LPG) and Anhydrous Ammonia Liquid

• Price Verification

Survey questions on the Retail Motor Fuel Dispensing Systems Exam indicated that the majority were somewhat or 

very satisfied with the test taking experience, that the exam questions were appropriate to the basic level inspector, 

that the questions were straight forward and clearly written, and that they were able to finish in the allotted time. 

The only problems identified seemed to be related to computer connections and loading of graphics. NCWM staff 

worked with the testing service to mitigate these issues. 

On the issue of using NCWM professional certifications for RSAs, the majority responded with interest in this area. 

The Committee worked with NCWM staff to solicit RSA volunteers to take the exam for free in order to obtain 

feedback. Volunteers who passed the exam would receive the formal certificate if they were members or if they pay 

the $75 testing fee as non-members. Four RSAs took the exam thus far and others are scheduled to take it. The 

Committee will gather additional data, evaluate the results and report at the Annual Meeting. 

2012 NCWM Interim Meeting: Several state officials questioned the appropriateness of charging these volunteers 

for the certificate if they are non-members. They noted that the service agents invested considerable time in taking 

the exam so that those who passed could have been rewarded with a waiver of the fee. M r. Onwiler, NCWM 

Executive Director, reported that the exam fee structure is controlled by the Board of Directors. The exam fee is 

waived for members as a way to improve membership value. The exam has always been available to service agents, 
PDC 2013 Final Report

Appendix B – History of Professional Certification Program

PDC - B6 

but this was a means of acquiring volunteers for data collection without making them pay fees as non-members. 

The Committee verified that participants were advised of the conditions when the volunteers were contacted. The 

Western Weights and Measures Association (WWMA) made a p roposal in 2011 that NCWM consider a t iered 

membership that would allow for a group rate category or reduced fees for non-members presently employed in a 

weights and measures related field wishing only to take the examinations. The Committee will ask the Board of 

Directors to consider these comments.

On the subject of the use of the current NCWM standard as the basis of all exams, the feedback from the survey 

clearly indicated that this should not be a problem for most jurisdictions. Therefore, the Committee will develop all 

exams based on the current editions of NCWM standards. 

Officials had concerns about preparing their workforce for taking the Retail Motor Fuel Dispensing Systems Exam. 

As the PDC proceeds in offering other certifications, the Committee wants jurisdictions and industry to feel 

supported and confident that the training they provide for their workforce will be comprehensive and will prepare 

their people to take the certification exams without providing them with the exam questions. T he Committee 

therefore recommends better communication so they understand what tools are available to help them create their 

own comprehensive training programs. The critical viewpoint is that a professional has to be prepared to perform 

the job and not just prepared to take the exam. This is the age old question of training to the learning objectives (the 

BOK) or training to the exam. The Committee strongly believes that training has to focus on the BOK and not on 

the exam questions. 

2012 NCWM Annual Meeting: The Committee met with the Board of Directors to provide an update on progress 

and agree on priorities. The Certification Coordinator reported that two additional question banks for small capacity 

scales and package checking had passed the technical review and were submitted to NCWM Headquarters. He also 

reported that SME volunteers are now working on the vehicle tank meter exam, and that he is expecting to start the 

search for SME volunteers for the medium and large capacity scale exams shortly after the Annual Meeting. NCWM 

Executive Director Don Onwiler reported that there has been a slight glitch in the system that must be corrected 

before two new the exams can be opened for use. This involves making sure that Headquarters controls the 

individual’s access to exams. Each candidate gets access to initially take the exam and then can get a retest if they 

fail. The original process had given the candidate access to all exams using the same credentials. As soon as this is 

corrected they will broadcast the availability of the two new exams.

The idea of accrediting the certification program was discussed. The Executive Director reported that he had been 

discussing the idea with the Institute for Credentialing Excellence (ICE) to see what parts of our program might be 

potential stumbling blocks. One area involves the SME’s who develop and vet the test questions. Our problem is 

that our SMEs are virtually all trainers within their jurisdictions and the vetting and training functions need to be 

separated. One possible avenue that we are pursuing is to restrict the access each SME has to the exam bank by only 

allowing them to review a part (~1⁄4) of the test bank. The advice also suggested that SMEs be asked to sign over 

rights to the test questions and that NCWM seek to copyright its exams. The Committee and the Coordinator will 

continue to work with the Executive Director toward the goal of meeting the accreditation standards and both the 

Coordinator and Headquarters will work on documenting procedures as a n ecessary step in that process. The 

Executive Director will continue to seek advice towards this long term project from ICE.

The Executive Director provided the Committee and the Board of Directors with following statistics on the Retail 

Motor Fuel Exam.

The Committee and the Board of Directors agreed that priorities will remain on the Professional Certifications. The 

Committee will not be pursuing the competency exams. This will help focus efforts to get the exams out based on 

priorities established by the survey the Committee conducted.

The Committee understands that the SMEs are the critical part of our certification program. The Committee wants 

to recognize those that are contributing and also encourage others to volunteer on future projects (i.e., the medium 

and large capacity scale exams that will start soon). To this end, the Committee wants to express gratitude by giving 

recognition to the following who contributed to the package checking and small capacity scale exams.

The Committee heard testimony from a number of individuals during the open hearings and appreciates the 

comments. In particular, the Committee is very pleased that states are starting to find ways to integrate our 

standards and the certifications in their programs. One state reported their efforts to mandate in regulation that 

RSAs get NCWM certification to demonstrate competence. Another is giving CEUs to county officials who obtain 

NCWM Certification. Others are using the exam results to evaluate their training efforts. One jurisdiction is using 

NCWM certifications in labor relations to demonstrate that retention and promotion decisions are being based on an

unbiased third party assessment. The CWMA is considering whether it might be possible to use the NCWM exam in 

their reciprocal testing program for RSAs. 

One state director reported that he had his entire staff take the RMFD exam. He provided some valuable feedback 

that the Committee and the Coordinator will consider. One involved making clear which version of the handbooks 

is being used in the exams. He also reported that candidates taking the exam wanted to learn about which questions 

they got wrong. He also wanted the Committee to look at extending the Certification Program to accredit the overall 

weights and measures program.

The Committee understands the concern about the wrong answers, but maintaining integrity of the test precludes us 

from giving that kind of specific feedback on the exam. At the end of the exam, the candidate is provided with the 

pass/fail on each segment of the exam and the final score. The candidate is also provided with the option of 

designating the e-mail address where the results will be sent. Thus, the results could go to a Supervisor or the 

Director. The Committee is considering avenues to provide feedback that will help states identify potential 

weaknesses in their training programs. Again, the Committee wants to divert the focus from the test back to 

ensuring mastery of the learning objectives in the BOK. To that end, the Committee is considering providing 

general statistics on each part of the exam so that a jurisdiction/company could compare their staff’s results with the 

composite of all those who took the exam. There is a further fear that providing detailed feedback on specific 

learning objectives where exam results showed low scoring would then divert the focus from the broad objectives of 

the BOK.

2012 CWMA Interim Meeting: T here was general support for removing much of the content in this item and 

making it reference material on the NCWM website. There was a question regarding how NCWM assesses exam 

difficulty and a suggestion to look at professional certification programs for other industries to see what the passing 

rates are and what they use to know if the exams are at the appropriate difficulty level. There were several 

suggestions to improve the exam process, including a flag button on each test question that test takers could select to 

notify that a specific question was problematic. Another was to provide a direct link at the end of the test to a 

survey site or other site for immediate feedback on the test. Another suggestion was to disclose to test takers which 

areas of NIST Handbook 44 they should study based on their results, without being told the actual questions that 

were incorrect. This would maintain the integrity of the test while providing guidance to the test taker.

2012 WWMA Annual Meeting: T he WWMA PDC chair presented a P owerPoint presentation reviewing the 

Professional Certification Program (PCP) entitled “Using the NCWM Program” during the open hearings. O ne 

comment/question was received during the open hearings regarding the time limit to take an exam after an 

individual has registered and received their passcode. The Committee, in conversation with the NCWM Executive 

Director by telephone, confirmed that there is no time limit for initial log in or between taking the first and second 

exam. Furthermore, if a NCWM member fails the second exam, he or she can reapply and retest until they pass the 

exam, free of charge. The Committee discussed the draft FAQ sheet developed by Ross Andersen and recognized 

that it is a good start and is in need of further development. The Committee is willing to assist with enhancing and 

clarifying this document. The Committee discussed the exam result data compiled on the three exams to date. The 

RMFD exam has been available since 2010. The Package Checking Basic and Small Capacity Scales Class III have 

been available since August 2012. The Committee recognized the likelihood that the pass/fail rate on the exams to 

date may not reflect the difficulty of the exam since many may be taking the exams to familiarize themselves with 

the exam process, not necessarily for obtaining the certificate. The Committee discussed accreditation of the PCP, 

the benefits to both industry and regulatory individuals, and the issue created by crossover between persons serving 

as both Subject Matter Experts (SMEs) and trainers. The Committee discussed the difference between certification 

to demonstrate basic competency, accreditation, and licensing with continuing education requirements. T he 

Committee believes that for the PCP to be accredited more information is needed about the specific accreditation 

requirements so the NCWM Professional Development Committee (NCWM PDC) can efficiently and correctly 

design the Program. The Committee encouraged the WWMA audience to take one or more of the three exams that 

are available. The Committee discussed the need for volunteer SMEs, exam results data and feedback on the exam 

taking experience, to assist the NCWM PDC in the continuous improvement of existing exams, and further 

development of future exams. F eedback can be submitted to the NCWM PDC through NCWM via e-mail 

to info@ncwm.net or call (402) 434-4880. The concept of free exams or a “rollback” in pricing for a period of time 

was discussed. There may be jurisdictions, business organizations, or other entities that desire to take the exams, but

find the cost of membership is prohibitive. The Committee believed there might need to be an initial incentive to 

encourage participation. The Committee recommends the following:

• NCWM survey jurisdictions to find out the number of Registered Service Agents (RSAs) within the 

jurisdiction, whether these jurisdictions require the RSA to pass an examination, and what fees and 

timelines are associated with these requirements. Determining the number of jurisdictions that require 

licensing and the content of their examinations (e.g., regulatory vs. technical requirements) would allow the 

NCWM PDC to evaluate the appropriateness of administering the same exams for RSAs or development of 

separate exams particular to RSAs. The jurisdictions using these written exams in their training programs 

could do so in conjunction with a field component to certify inspectors and RSAs. 

• NCWM Executive Director continue research into the accreditation requirements and recommend the 

appropriate accreditation body for the PCP; weights and measures jurisdictions and industry organizations 

that may require certification recognize the value and credibility provided through formal accreditation.

• NCWM PDC continues its work refining the PCP FAQ Sheet. The WWMA PDC Committee is willing to 

assist with enhancing and clarifying this document. The PCP FAQ Sheet is a valuable tool for new exam 

takers.

• NCWM PDC consider implementing a policy of offering newly introduced exams at a reduced price for a 

fixed period of time (e.g., $30 per exam for six months, providing the exam taker agree to provide feedback 

on the exam contents and exam taking experience before receiving their certificate). NCWM needs to 

encourage the widest possible participation in the early stages of PCP development. To bring the PCP to 

full program fruition, offering incentives to exam takers may assist the NCWM in reaching its goals.

One jurisdiction indicated that they would begin using the examinations as part of their annual performance plans 

and performance evaluations for their staff. T he Committee realized that the PCP was originally designed for 

weights and measures officials, but discussed whether the exams should be modified for RSA to put more emphasis 

on proper calibrations, sealing, etc.

Carryover Item 401-3 (This item originated from the Committee and first appeared on its agenda in 2003.)

Background/Discussion: 

Prior to the 2010 Annual Meeting, Ms. Georgia Harris, NIST, OWM provided the Committee with reference 

material on teaching methods and assessment of training success. Distilling the essence of these materials, the 

Committee believes that instructors need training in more than just the technical material; they need training in 

setting the learning objectives, developing the training materials with those objectives in mind, selecting training 

methods that incorporate adult learning styles, and evaluating the effectiveness of their training.

Education Subsystem

The chart below covers three levels of learning objectives and relates them to (1) the training activities most likely to 

be successful and (2) the best methods for assessing the success of the training. The curriculum segments state the 

learning objectives using verbs similar to those in the bottom row of the table. T hese drive both the training 

activities required to promote adult learning and the assessment tools appropriate to measure success at that level.

webpages. The importance of pre-training analysis and post-training evaluation cannot be overestimated. Failure to 

include these steps often leads to failure of training efforts.

Professional Certification Program

Systems Approach to Training Evaluation

The Committee is calling on the states and other training developers to implement the Analysis, Design, 

Development, Implementation, and Evaluation (ADDIE) model in their training preparations and post training 

evaluation. E veryone needs to participate in the development of new BOK modules and then encourage their 

trainers to use existing BOK modules in their training plans.

The Committee encourages members to also look at the presentation on A Complete Training Program prepared by 

Ms. Carol, Hockert, NIST, OWM. The presentation outlines ways to develop training programs and improve 

instruction of weights and measures material. Contact Ms. Hockert for a copy.

2012 NCWM Interim Meeting: Advisors from NIST, OWM, reported that they are using NCWM BOK in preparing 

new training initiatives. They are stressing adult learning techniques, particularly focusing on the use of hands-on 

training as the most popular and effective training tool. This ties in closely with the new baseline competency 

exams discussed in Item 410-1. NIST, OWM is using these exams to ensure students in NIST sponsored training 

courses are competent in prerequisite course materials prior to taking training. They reported that they are already 

drafting questions for the baseline competency exams. They see significant efficiencies in using NCWM testing 

services for this purpose since they are already in place. 

Ms. Hockert, NIST, OWM, recommended a basic math prerequisite for persons taking Metrology or other related 

weights and measures courses sponsored by NIST. The math exam would allow trainees to demonstrate entry level 

math skills and make the training process more efficient and effective. O ne official discussed the California 

licensing requirement of a college degree which requires a certain number of math courses and asked if this would 

satisfy the need for the math prerequisite. S everal California officials expressed concern about the Professional 

Certification Program replacing existing state licensing programs, and if adopted, it might require amendment of 

existing state statutes. B ecause math competency is an essential skill for weights and measures work, the 

Committee recommends that the PDC include in its scope the development of an exam to demonstrate basic math 

competency before taking the Fundamentals of Metrology or other training courses at NIST.

2011 SWMA Annual Meeting: I t was stated that we should consider training state trainers on adult learning 

techniques as well as subject matter. No further recommendations were made.

2012 NCWM Annual Meeting: T he Committee stressed instructor improvement. The Committee reviewed the 

importance of using the NCWM learning objectives and the ADDIE model in training. This stresses the importance 

of training to the goals in the BOK and not training to pass the test. If the training is appropriate and has been 

delivered effectively, the employee should have no problem passing a fair exam. The end is not a certificate on the 

wall, but rather a competent inspector. In other words,

JOB SUCCESS = EXAM SUCCESS

Ms. Hockert stressed that good training requires a partnership between the trainee, trainer, and the supervisor. The 

Committee agrees that buy-in from all levels is critical to training success.

2012 CWMA Interim Meeting: T he Committee recommended archiving most of the content in this item to the 

NCWM website as reference material.

2012 WWMA Annual Meeting: T he Committee noted that it is in the best interest of NIST and NCWM that 

regional training efforts are of the highest quality and uniform throughout the United States. The Committee 

recommends the following:

• Regional trainers be selected as per the process agreed upon between NIST and NCWM;

• Regional trainers receive courses on adult learning techniques and converting technical information into 

training materials; 

• Regional trainers be afforded the opportunity to shadow NIST trainers as they perform training in 

individual jurisdictions; and

• The use of funds from the Associate Membership Committee or the NIST Training Initiative Grant be 

made available for this purpose.

2012 NEWMA Interim Meeting: Members expressed interest in NIST Train-the-Trainer classes. A demonstration 

was provided on how to access materials for taking the Professional Certification Exams and then for taking the 

exams. The Committee encouraged those in attendance to seek certification of their inspectors.

510-1 I Mutual Recognition Arrangement (MRA)

Background/Discussion: 

The MRA between Measurement Canada (MC) and NTEP labs originated April 1, 1994. S ince that time, the 

original MRA has expanded, and a second MRA covering measuring devices was developed. O n Tuesday, 

July 19, 2011, NCWM Chairman Mr. Tyson and MC President Mr. Johnston signed a renewal MRA that combines 

the weighing and measuring devices into one document and provides for continued cooperation between the two 

organizations and continuation of the beneficial partnership. The new MRA is effective for five years.

The scope of the current MRA includes:

• gasoline and diesel dispensers;

• high-speed dispensers;

• gasoline and diesel meters intended to be used in fuel dispensers and truck refuelers;

• electronic computing and non-computing bench, counter, floor, and platform scales with a capacity up to 

1000 kg (2000 lb);
NTEP Committee 2013 Final Report

NTEP - 4 

• weighing/load receiving elements with a capacity of up to 1000 kg (2000 lb);

• electronic weight indicating elements (except those that are software based (i.e., programmed by 

downloading parameters); and

• mechanical scales up to 10 000 kg (20 000 lb).

The Committee continues working with MC to explore the possibility of expanding the scope to include Multiple 

Dimension Measuring Devices (MDMD) and higher capacity scales. Technical obstacles have prevented inclusion 

of both MDMD and higher capacity scales for now, but NTEP and MC remain committed to continue to discuss 

expansion. NTEP also requested that tests conducted at manufacturers’ premises under the supervision of an NTEP 

evaluator be included in the scope of the MRA. MC expressed the desire to keep these evaluations outside the scope 

of the MRA for scales, load receiving elements, and electronic weight indicating elements.

MC, NTEP, and all of our mutual stakeholders agree that the MRA is a benefit for the North American weights and 

measures industry. The NTEP Committee appreciates the efforts and cooperation of Measurement Canada.

NCWM private sector members continue to reiterate their desire to see Multiple Dimension Measuring Devices 

included under the MRA. Measurement Canada and the NTEP Committee continue to discuss and evaluate matters 

regarding such an expansion of the MRA.

2013 Annual Meeting: Measurement Canada agreed to give further consideration to expansion of the MRA to 

include MDMDs and to recognition of data collected by NTEP evaluators at manufacturing facilities.

Mettler-Toledo commented that their company has experienced MRA application issues due to differences in the 

test weights used for evaluation of high precision Class I and II balances. N TEP will discuss the issues with 

Measurement Canada.

510-2 I Mutual Acceptance Arrangement (MAA)

Background/Discussion: 

Information regarding the International Organization of Legal Metrology (OIML) MAA can be found 

at www.oiml.org/maa. N CWM has signed the OIML MAA Declaration of Mutual Confidence (DoMC) for 

Recommendation (R) 60 Load Cells as a utilizing participant. A utilizing participant is a participant which does not 

issue any OIML Certificate of Conformance (CC) nor OIML Test Reports and/or Test Reports under a DoMC but 

does utilize the reports issued by issuing participants.

The OIML Technical Subcommittee (SC) for Technical Committee (TC) 3/SC 5 Conformity Assessment made 

revisions to the following OIML Basic Publication (B) documents:

• OIML B 3, OIML Certificate System for Measuring Instruments; and 

• A combined revision of OIML B 10-1, Framework for a Mutual Acceptance Arrangement on OIML Type 

Evaluations, and OIML B 10-2, Checklists for Issuing Authorities and Testing Laboratories carrying out 

OIML Type Evaluations. 

January 2011 Interim Meeting: The Committee reviewed four items related to the revisions of B 3 and B 10: (1) 

housekeeping revisions to document B 3; (2) housekeeping revisions to B 10; (3) revisions to B 10 that would 

incorporate provisions under which manufacturers’ test data would be accepted under the MAA, and (4) a resolution 

of compromise whereby countries may voluntarily accept manufacturers’ test data. The Committee recommended 

that the Board of Directors authorize the U.S. representative to vote YES on items (1) and (2), NO on item (3), and 

YES on item (4) with a qualifying statement that the United States would not accept any MAA certificates based on 

manufacturers’ test data. The Board of Directors voted to support all of the recommendations from the NTEP 

Committee.
NTEP Committee 2013 Final Report

NTEP - 5 

A meeting of the Committee on Participation Review for R 60 and R 76 was held September 21 - 23, 2011, in 

Braunschweig, Germany. Dr. Ehrlich, National Institute of Standards and Technology (NIST), Office of Weights 

and Measures (OWM); Mr. Barton, NIST, OWM; and Mr. Truex, NCWM attended the meeting.

The International Committee of Legal Metrology (CIML) Preliminary Ballots on B 3 and B 10 closed in July 2011 

without any negative votes, and a final CIML vote was held at the CIML Meeting in Prague in October 2011. Both 

B 3 and B 10 passed the CIML vote. International comments on a new document entitled The Role of Measurement 

Uncertainty in Conformity Assessment Decisions in Legal Metrology have been received and the Secretariat is using 

them to develop the 2 Committee Draft (CD). 

The CIML, noting the report of TC 3/SC 5 on the issue of the acceptance of manufacturers’ test results within a 

DoMC under the MAA, and recalling its Resolution no. 20 at the 43rd CIML Meeting, decided that Issuing 

Participants may request the registration of Manufacturers’ Testing Laboratories (MTLs) under a DoMC, provided 

that the conditions agreed by TC 3/SC 5 and laid down in a respective amendment to, or revision of, OIML B 10 are 

met, and that, after this amendment to, or revision of, OIML B 10, MAA Type Evaluation Reports that contain test 

results from MTLs may be accepted by Participants on a voluntary basis.

The CIML approved as a new work item for OIML TC 3/SC 5. 

• The amendment to or the revision of, OIML B 10 Framework for a MAA on OIML Type Evaluations 

MAA to include appropriate conditions for the registration of MTLs under a DoMC. 

The CIML also decided that the registration of MTLs under a DoMC remains excluded from the scope of the MAA 

until this amendment to, or revision of, OIML B 10 is approved. TC 3/SC 5 voted in May 2012 to approve a 2 CD 

of an Amendment to OIML B 10 that would permit, on a strictly volunteer basis, the use of test data from MTLs in 

the MAA. The United States (NTEP) supported this 2 CD with the provision that the use of manufacturer test data 

was clearly identified on the MAA test report because NTEP cannot use manufacturer test data towards issuance of 

an NTEP certificate. The 2 CD was modified accordingly, after which the CIML voted and approved the 

Amendment to B 10 to allow the inclusion of test data from manufacturers, on a strictly voluntary basis, at its 

October 2012 meeting in Bucharest, Romania.

Dr. Ehrlich gave an update to the Committee during the 2013 Interim Meeting, reviewing the history of the above 

discussions, deliberations, and CIML votes, confirming that the outcomes aligned with the Committee's 

recommendations and the instructions provided by the NCWM Board of Directors.

From January 2011 to December 2012, nineteen NTEP certificates for load cells were issued under the MAA. All to date 

have been tested by the National Measurement Institute in The Netherlands. The NTEP Administrator reviewed the test 

data and drafted the CCs.

Dr. Ehrlich requested in January that NCWM review its MAA policy regarding participation in R 76. The NCWM 

Board recapped the decision process to participate as a utilizing participant for R 60. Existing policy from 2006 is 

not to participate in R 76 until NCWM is able to do so as an Issuing Participant. The Board revisited the 2006 

discussions leading to that decision, including considerations for NTEP labs’ workload, potential lost expertise, 

concerns with quality of evaluations at some foreign labs, etc. D r. Ehrlich wanted NCWM to reconsider and 

become a utilizing participant for OIML R 76. Some U.S. manufacturers support NCWM policy, but others would 

like to have one-stop shopping. The MAA also includes R 51 (water meters) and R 117 (RMFD) may be added 

soon. Since there are no new developments to effect the decision, the NCWM Board of Directors agree to maintain 

existing policy at this time.

520 ACTIVITY REPORTS

520-1 I NTEP Participating Laboratories and Evaluations Reports

Background/Discussion: 

During the 2012 Annual Meeting, Mr. Truex, NTEP Administrator, updated the Committee on NTEP laboratory and 

administrative activities.

The NTEP weighing and measuring laboratories held a joint meeting April 2 - 5, 2012, in Columbus, Ohio. The 

NTEP weighing laboratories met again in August 2012 prior to the meeting of the NTEP Weighing Sector in 

Annapolis, Maryland, and the NTEP measuring laboratories met once more in October 2012, prior to the NTEP

Measuring Sector meeting in Louisville, Kentucky. 

The Committee announced plans to conduct a survey of NTEP customers and NTEP laboratories regarding customer 

service. The board plans to use the results of the survey to form a continuous improvement plan for NTEP. A small 

work group was formed to get the project started. The resulting draft was presented to the board during the 

2011 Annual Meeting in Montana. With any survey, the challenge is to develop a document that is concise enough 

that customers will respond, while also providing a meaningful set of data. The survey was released to active CC 

holders. The NCWM Board of Directors reviewed the survey results in October 2011, finding general approval of 

NTEP services. 

The New York brick and mortar NTEP laboratory for weighing devices is staffed and accepting NTEP evaluation 

assignments. The NTEP Committee realizes the other weighing laboratories worked very hard to assume additional

workload while the NY laboratory was off line and commends the labs for keeping the backlog at a minimum and 

completing evaluations in a timely manner.

Mr. Truex reported to the Committee that incoming applications remain comparable to normal. He reported there is 

no backlog concern for measuring devices and the brick and mortar weighing labs at this time.

The NTEP laboratories, NTEP Committee, and NCWM Board of Directors expressed appreciation to Gilbarco for 

allowing the NTEP measuring laboratories to utilize their facilities and equipment for hands on training in April. 

Special thanks were extended to Gordon Johnson and Gilbarco employees that participated in the training exercises.

The Committee reviewed NTEP statistics through June 2013 (see Appendix A). The review of statistics shows that 

incoming applications are relatively comparable to normal, and there exist no significant laboratory backlog issues.

520-2 I NTEP Sector Reports

Background/Discussion: 

All NTEP Sector reports were available to members at the time NCWM Publication 15 was published. The NTEP 

Committee is committed to ensuring that electronic versions of sector reports continue to be available with NCWM

530 CONFORMITY ASSESSMENT PROGRAM

530-1 I Conformity Assessment Program

Background/Discussion: 

The Conformity Assessment Program was established to ensure devices produced after the device has been type 

evaluated and certified by NTEP continue to meet the same requirements. This program has three major elements: 

1) Certificate Review (administrative); 2) Initial Verification (inspection and performance testing); and 3) Verified 

Conformity Assessment (influence factors). This item is included on the Committee’s agenda to provide an update 

on these elements.

Certificate Review: 

Certificates are constantly under review by NTEP staff and laboratories. Many active certificates are amended 

annually because of manufacturer submission for evaluation or issues reported by the states pertaining to 

information on the certificate. When the devices are re-evaluated and certificates are amended, all information is 

reviewed and necessary steps are taken to assure compliance and that accurate, thorough information is reported on 

the certificate.

In an effort to keep certificate information up to date, the Committee continues to offer an opportunity for active 

certificate holders to update contact information that is contained in the “Submitted By” box on certificates. This is 
NTEP Committee 2013 Final Report

NTEP - 9 

offered during the payment period of their annual maintenance fee. Many Certificate of Conformance (CC) holders 

have taken advantage of the opportunity.

Initial Verification (IV): 

The IV initiative is ongoing. Field enforcement officials perform an initial inspection and test on new installations 

on a routine basis. The Committee recognized that the states do not want IV reporting to be cumbersome. 

An IV report form has been developed. The Committee desired a simple form, perhaps web-based for use by state 

and local regulators. The form has been approved by the Committee and distributed to the states. A completed form 

can be submitted via mail, e-mail, fax, or online. The form is available to regulatory officials who are members of 

NCWM at www.ncwm.net/ntep/conformity/verification. 

Verified Conformity Assessment Program (VCAP): 

NCWM has been concerned about production meeting type and protecting the integrity of the NTEP CC since the 

inception of NTEP. The board has consistently reconfirmed its belief that conformity assessment is vital to NTEP’s 

continued success. 

Load cells traceable to NTEP certificates were selected for the initial assessment effort. NCWM elected to require a 

systems audit checklist that is to be completed by an outside auditor and submitted to NCWM per Section 2.5 of the 

VCAP requirements. A VCAP Systems Audit Checklist for Manufacturers and a VCAP Systems Audit Checklist 

for Private Label Certificate Holders have been developed and are available on the website 

at www.ncwm.net/ntep/conformity/vcap/checklists-faqs. Additionally, the Committee developed a new NCWM 

Publication 14, administrative policy to distinguish between the requirements for parent NTEP certificate holders 

(S.1.c.) and private label certificate holders. The requirements in S.1.d. track the private label checklist 

requirements: traceability to parent NTEP CC, traceability of the private label cell to a VCAP audit, purchase, and 

sales records, plan to report non-conforming product and non-conforming product in stock, plan to conduct internal 

audits to verify non-compliance action, and internal audit records. 

As a result of VCAP activities, 24 load cell certificates, involving 12 different certificate holders, were changed to 

“inactive” status. 

The Committee announced that the next device category is weighing/load receiving elements, 1000 kg (2000 lb) 

capacity and less, using load cells that are not traceable to their own NTEP certificate. The following compliance 

timeline was developed for weighing/load receiving element CC holders with active certificates using non-NTEP 

load cells. The Committee encourages affected certificate holders to start the process immediately.

NTEP Committee 2013 Final Report

NTEP - 10

2013 NCWM Interim Meeting: it was reported that 25 weighing element certificate holders (46 active NTEP CCs) 

have been identified and all have been notified. The following disclaimer has been advertised and communicated by 

NCWM: "NCWM is working to identify all active certificates for weighing elements 1000 kg (2000 lb) capacity 

and less, using non-NTEP load cells. As a courtesy, certificate holders are being notified of VCAP requirements 

and the established time line. Please note that the NCWM Board of Directors does not consider it to be NCWM's 

responsibility to notify all certificate holders and affected certificates. C ertificate holders are responsible for 

reviewing their active NTEP certificates and compliance with VCAP."

The Committee received two letters, a l ist of questions, and many other inquiries pertaining to VCAP. The 

Committee worked diligently to answer the questions submitted in a very timely manner. The Committee 

anticipated that additional questions would be posed and considered the potential need to form a VCAP Committee. 

Certificate holders and other interested parties were encouraged to submit written questions to the NTEP Committee 

so decisions could be made regarding the need for a VCAP Committee and, if needed, the make-up of the group. 

The Committee is pleased to report that it was successful in answering all the questions to date. Clerical changes 

have been made to affected VCAP documents.

Recurring questions involve the five remaining device types under the VCAP umbrella. When will these remaining 

device types be added to the VCAP program? Will they be added all at one time or only a single device type every 

two to three years? The Committee is very carefully considering possible options. With each device type added to 

the VCAP, the administrative overhead of NTEP increases proportionately. At the present time, additional device 

types cannot be added until increased capacity within NTEP administration is achieved. T he NCWM Board is 

currently reviewing alternatives to this increase in capacity, including consideration of an option to add all of the 

remaining device types at one time. There is no formally accepted schedule for completion of this effort.

Seven weighing device categories subject to influence factors, as defined in NIST Handbook 44, were identified and 

are subject to VCAP audits. The VCAP process requirement is ongoing for load cells and weighing elements that 

use non-NTEP load cells. The five remaining device categories are: indicating elements, complete scales, 

automatic weighing systems, belt-conveyor scales, and automatic bulk weighing systems. Certificate holders for 

these device types are encouraged to take note that the NTEP Committee and NCWM Board is seriously considering 

the application of the VCAP requirement to all five remaining categories in the very near future. If and when the 

VCAP requirements are applied the certificate holder would be required to have an on-site audit of the 

manufacturer's quality system and on-site random and/or review of a production device by an outside auditor to 

verify compliance with VCAP. C ertificate holders are encouraged to research the VCAP requirements on the 

NCWM website under the NTEP, Conformity Assessment section. Certificate holders are encouraged to review the 

VCAP requirements applicable to their devices and report concerns to the NTEP Committee.

There was discussion on the required number of audits for facilities that manufacture multiple device types. For 

example, if a company had successful audits for two device types, they might submit a request for a delay from audit 

requirements for remaining device types, stating that they are all subjected to the same processes and will be audited 

in the next cycle. The Committee agreed to the request in principal and directed the NTEP Administrator to develop 

NCWM policy language for consideration during the next Board meeting.

Cardinal Scale suggested that all additional device categories subject to VCAP be included under the VCAP 

umbrella all at once and in the near future. The NCWM NTEP Committee and Board of Directors want to again 

stress to NTEP Certificate holders that they must pay attention to the continued progress of VCAP as it applies to 

their devices. Certificate holders are encouraged to expand their current VCAP audit certification to include the 

other device categories likely to be included under the VCAP umbrella in the near future.

NTEP Staffing for VCAP Workload: Comments on the proposal to hire another NTEP staff person have been 

positive. The Board discussed the extensive travel requirements for the person and reviewed the duties and desired 

qualifications. The decision was made to advertise the position with applications due by July 31, 2013, and the goal 

to have the person on staff sometime in November.

530-2 I Conformity Assessment Program – NTEP Administrative Policy

Source: 

NTEP Committee

Purpose:

Clarify the intent of NCWM Publication 14, Administrative Policy, Conformity Assessment Process.

Item Under Consideration:

The 2013 Version of NCWM Publication 14 reflects these changes.

S.1.c. NTEP Verified Conformity Assessment Program Procedures

Introduction

Many NTEP certified devices must meet NIST Handbook 44 requirements for influence factors. It is not 

possible to verify these requirements during the Initial Verification in the field. Therefore, manufacturers 

of metrological devices (instruments) and/or components (modules) which are subject to influence factors, 

as defined in NIST Handbook 44, must have a Verified Conformity Assessment Program (VCAP) in place 

to ensure that these metrological devices and/or components are produced to perform at a level consistent 

with that of the device and/or component previously certified.

The Verified Conformity Assessment Program audit will be at one or more sites as required to verify 

compliance.

For weighing devices that are subject to influence factors, NTEP will require an initial on-site audit of the 

manufacturer's quality system and on-site random testing and/or review of a production device(s) 

(instrument[s]) by the Registrar to verify that all items listed below are currently implemented and 

functioning to verify compliance to the appropriate sections of NIST Handbook 44. 

It is important for NTEP to know the types of devices included in the VCAP audit and it is for this 

reason that the certificate holder shall prepare a controlled Quality Management System (QMS) 

document listing the range of parameters that cover the devices included in the audit. The certificate 

holder shall include in this document all certificates and device parameters (For example: different 

models, capacities, e-min, n-max, sizes etc.) for the applicable device category. For example, in a load 

cell audit, a range of capacities of the load cells included in the audit shall be listed in the report. 

This document shall be available for the VCAP auditor and NTEP upon request and may be 

included as an annex to the audit report if desired.

Amend Section S.1.c.1.4. as follows:

1.4 An appropriate sampling plan and acceptance criteria is in place and operating.

1.4.1. The NTEP CC holder shall establish a random sampling plan appropriate for the production 

quantity of the device that is traceable to a n ationally recognized quality standard, i.e., Acceptable 

Quality Level (AQL) or equivalent, or meet the minimum requirements as defined in Section 4 of this 

document.

1.4.2. The NTEP CC holder shall maintain a controlled document listing all the devices, their 

estimated annual production quantity, the CC number of the device and the date that the device 

was added to or removed from the sampling plan.

1.4.23. Devices shall be selected and tested in accordance to NCWM Publication 14 as designated by 

the established sampling plan.

1.4.34. Results of the testing, along with values of pertinent control parameters (e.g., time, 

temperature, humidity, etc.), shall be recorded and shall clearly identify whether the test passed or 

failed.

1.4.45. Records shall be made available to the VCAP auditor of test results since the last VCAP audit.
NTEP Committee 2013 Final Report

NTEP - 12

Amend Section S.1.d as follows:

d. NTEP Verified Conformity Assessment Program Procedures for Private Label Certificate Holders

Introduction

Many NTEP certified devices must meet NIST Handbook 44, Specifications, Tolerances, and Other 

Technical Requirements for Weighing and Measuring Devices, requirements for influence factors. It is not 

possible to verify these requirements during the Initial Verification in the field. Therefore, manufacturers 

of metrological devices (instruments) and/or components (modules), which are subject to influence factors, 

as defined in NIST Handbook 44, must have a Verified Conformity Assessment Program (VCAP) in place 

to ensure that these metrological devices and/or components are produced to perform at a level consistent 

with that of the device and/or component previously certified.

For weighing devices that are subject to influence factors, traceable to a private label NTEP Certificate of 

Conformance, NTEP will require the private label certificate holder to verify that the parent certificate 

holder has complied with VCAP requirements, has a current VCAP audit certificate, the VCAP 

certification is traceable back to the parent NTEP certificate, and the parent certificate is active.

It is important for NTEP to know the types of devices included in the VCAP audit and it is for 

this reason that the certificate holder shall prepare a controlled Quality Management System 

(QMS) document listing the range of parameters that cover the devices included in the audit. 

The certificate holder shall include in this document all certificates and device parameters (for 

example: d ifferent models, capacities, e-min, n-max, sizes etc.) for the applicable device 

category. For example, in a load cell audit, a range of capacities of the load cells included in the 

audit shall be listed in the report. This document shall be available for the VCAP auditor and 

NTEP upon request and may be included as an annex to the audit report if desired.

Amend Sections S.1.d.1. by adding a new Section 1.3. as follows and renumbering subsequent sections:

1.3. The private label certificate holder shall maintain a controlled document listing all the private 

label devices, the suppliers' name and the date the private label agreement was initiated or cancelled. 

Background/Discussion:

It has been recommended to the Committee that the VCAP requirement and other conformity assessment documents 

be clarified. The amendments proposed above reflect the primary significant changes. The Committee discussed 

the recommended changes and concluded they were clerical in nature and did not affect the integrity of VCAP or 

change the intent of the VCAP requirements. If the changes above are accepted, it will be necessary to incorporate 

the changes into the two checklists (parent CC holder and private label CC holder), the VCAP supplemental guide, 

and other electronic documents on the NCWM website as deemed appropriate.

The Committee did not receive any negative comments about the proposed changes. During the Interim Meeting, 

the Committee recommended to the NCWM Board that the changes be accepted and incorporated into the 

2013 version of NCWM Publication 14. The Board approved the recommendation and authorized NTEP to move 

forward accordingly.

540-1 I Administrative Policy Section Format

Source: 

NTEP Committee
NTEP Committee 2013 Final Report

NTEP - 13

Purpose:

Revise the format of NCWM Publication 14, Administrative Policy section by converting to a numbering format and 

putting content in more logical order.

Background/Discussion:

NCWM is working to revise NCWM Publication 14, Administrative Policy to arrange content in a more logical 

order and to develop a more understandable form. The purpose is not to change the intent of the publication, but to 

realign and clarify sections as necessary. During 2012, NTEP Sectors and the NTEP labs were asked to review the 

revised section, "NTEP Administrative Policy," and provide feedback. An electronic copy of the revised document 

was shared with members of the Sectors and NTEP lab representatives.

The Committee did not receive any negative comments about the proposed changes. During the Interim meeting, 

the Committee recommended to the NCWM Board that the changes be accepted and incorporated into the 

2013 version of NCWM Publication 14. The Board approved the recommendation and authorized NTEP to move 

forward accordingly. The 2013 version of NCWM Publication 14 reflects these changes.

540-2 I Administrative Policy Section – NTEP Advisory Committee

Source: 

NTEP Committee

Purpose:

Update NCWM Publication 14, Administrative Policy (A.10. and B.5.) to reflect current practice.

Item Under Consideration:

Amend NCWM Publication 14, Administrative Policy as follows:

Delete sections A.10. and B.5. providing for an "NTEP Advisory Committee." 

A.10. NTEP Advisory Committee - An ad hoc committee that reviews long range plans and recommends 

policy changes to the NTEP Committee.

B.5. The Advisory Committee is an ad hoc committee that recommends policy and long range planning 

to the NTEP Committee. The Advisory Committee meets as needed and is made up o f members 

appointed by the NTEP Committee Chair, representing all segments of NCWM.

Background/Discussion:

The NTEP Committee was unable to verify that an NTEP Advisory Committee has ever been officially appointed by 

any NTEP Committee Chair. The charges of long range planning and policy changes are fulfilled by the NCWM 

Board of Directors. The Committee did not receive any negative comments about the proposed changes. During the 

Interim Meeting, the Committee recommended to the NCWM Board that the changes be accepted and incorporated 

into the 2013 version of NCWM Publication 14. The Board approved the recommendation and authorized NTEP to 

move forward accordingly.

540-3 I Administrative Policy Section – National Type Evaluation Program Technical Committees

Source: 

NTEP Committee

Purpose:

Change the name of the Sectors from "National Type Evaluation Technical Committee" (NTETC) to "NTEP 

Sectors."
NTEP Committee 2013 Final Report

NTEP - 14

Item Under Consideration:

The 2013 Version of NCWM Publication 14 reflects these changes.

A.14. National Type Evaluation Technical Committee Program Sector (NTETCNTEP Sector) 

A Committee that develops and recommends test criteria and procedures to the NTEP Administrator, known as 

a “Sector” (e.g., Weighing Sector).

B.3. National Type Evaluation Technical Committee Program Sector (NTETC NTEP Sector) 

The National Type Evaluation Technical Committees Program Sectors (NTETC or NTEP Sectors) have the 

responsibility of advising the NTEP Administrator by developing and recommending test criteria and 

procedures for use in the evaluation process by the Participating Laboratories. The NTETCNTEP Sectors also 

may recommend specific changes to NIST Handbook 44 to assure consistency between the handbook and the 

checklist published in NCWM Publication 14. 

Meetings are held annually, or as needed and are open to all NCWM members and other registered parties. 

An NTETCNTEP sector seeks to form a consensus among all parties in attendance. Sectors are formed to 

address specific device areas of NTEP (e.g., weighing, measuring, grain moisture). Each Sector has a 

chairperson that is appointed by the NTEP Committee Chair. There is no fixed term for this position. 

The NTETC NTEP Sector Chair must be a current member of NCWM.

If for any reason an NTETC NTEP Sector member cannot attend the scheduled meeting, he/she may designate 

an alternate, with prior approval of the NTETCNTEP Sector Chair. This alternate will have the same voting 

rights as the NTETC Sector member they replace, for that particular meeting. 

The membership and voting status of the NTETC NTEP Sector is as follows:

Background/Discussion:

The term “National Type Evaluation Technical Committee (NTETC)" has reportedly led to confusion by many 

individuals over the years. The Committee believes that changing the name to “NTEP Sectors” may simplify 

understanding and reflect the role of the Sectors. T he Committee acknowledges that, if the name change is 

approved, references to NTETC throughout NCWM Publication 14 will need to be changed. The Committee did not 

receive any negative comments about the proposed changes. During the Interim Meeting, the Committee 

recommended to the NCWM Board that the changes be accepted and incorporated into the 2013 version of NCWM 

Publication 14. The Board approved the recommendation and authorized NTEP to move forward accordingly.

550 OTHER ITEMS – DEVELOPING ITEMS

550-1 D NTEP Contingency Plan

Source: 

NTEP Committee

Purpose: 

NTEP Contingency Plan was created to keep NTEP operating and to ensure that NTEP services are available at an 

adequate level including an appropriate number of laboratories and personnel (evaluators) to maintain viable support 

for NTEP services, including MRAs, MAAs, and potentially to be an R 76 Issuing Participant.

Item Under Consideration: 

The NTEP Committee discussed contingency planning for continuity of NTEP operations. With the state of today’s 

economy, one of the NTEP-authorized labs could close due to government budget cuts. How would NTEP maintain 

workflow? Are there additional states interested in applying to become an NTEP field lab or an NTEP brick-andmortar lab? T he Committee will continue to discuss these issues during a long-range planning session and 

welcomes comments from the membership.
NTEP Committee 2013 Final Report

NTEP - 15

Background/Discussion:

The Committee continues to consider whether NCWM should:

1. Employ NTEP evaluators to conduct testing at manufacturers’ facilities?

2. Have evaluators under contract to conduct testing at manufacturers’ facilities?

3. Employ NTEP evaluators or have evaluators under contract to assist the state NTEP laboratories?

4. Have a brick and mortar NTEP laboratory and NTEP evaluators?

5. Use a private third party laboratory to conduct NTEP evaluations?

The Committee has heard testimony expressing support and concerns pertaining to the options. Several stated that 

the Committee should consider adding OIML MAA participation as a Utilizing Participant to the list. Others have 

urged the Committee to continue working on the idea of NCWM NTEP evaluators, an NCWM NTEP lab, and 

keeping all options open. One member asked the Committee to consider accepting manufacturer compliance data in 

lieu of hiring NTEP contractors. Another suggestion from the floor was to consider strengthening and utilizing IV 

as part of the NTEP process. A representative of a state brick and mortar NTEP laboratory asked the Committee to 

move cautiously forward and not destroy the state NTEP labs. He expressed concern that the establishment of an 

NCWM NTEP brick and mortar lab could lead to significant legal complications for the states.

The Committee reiterated to the membership that, at this time, the preferred course of action would be the option of 

evaluators under contract. The Committee recognizes the commitment that the states with NTEP laboratories have 

made over the years and would only resort to contingency measures in the event of a severe loss of state lab 

resources. Labs are handling current demands without a need for contingency measures. The Committee is updated 

on the status of the participating laboratories, personnel, and backlog on a quarterly basis and will continue to keep 

NTEP contingency a priority.

Belt-Conveyor Scale (BCS) Sector Meeting Summary

February 23, 2012

St. Louis, Missouri

INTRODUCTION

The charge of the BCS Sector is important in providing appropriate type evaluation criteria based on specifications, 

tolerances and technical requirements of NIST Handbook 44 Sections 1.10. General Code and 2.21. Belt-Conveyor 

Scale Systems. The Sector’s recommendations are presented to the NTEP Committee each January for approval and 

inclusion in NCWM Publication 14, Technical Policy, Checklists and Test Procedures for national type evaluation.

The Sector is also called upon occasionally for technical expertise in addressing difficult NIST Handbook 44, 

Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices issues on the 

agenda of the National Conference on Weights and Measures (NCWM) Specifications and Tolerances Committee. 

Sector membership includes industry, NTEP laboratory representatives, technical advisors and the NTEP 

Administrator. Meetings are held annually, or as needed and are open to all NCWM members and other registered 

parties.

Suggested revisions are shown in bold face print by striking out information to be deleted and underlining

information to be added. Requirements that are proposed to be nonretroactive are printed in bold faced italics. 

Note: It is the policy of the National Institute of Standards and Technology (NIST) to use metric units of measurement in 

all of its publications; however, recommendations received by NCWM technical committees and regional weights and 

measures associations have been printed in this publication as submitted. Therefore, the report may contain references in 

inch-pound units.

CARRY-OVER ITEMS

1. Belt-Conveyor Scale NTEP Checklist

Source:

NIST, OWM

Background/Discussion:

Prior to the 2009 NTETC BCS Sector Meeting, Mr. Ripka, Chair submitted a d raft of an amended NCWM 

Publication 14, Belt-Conveyor Scales Technical Policy, Checklists, and Test Procedures to the sector members for 

review. T he changes in this draft related primarily to Master Weight Totalizers intended to be installed as 

substitutions within a BCS system in addition to a number of other minor editorial changes. Among the suggested 

changes that were included in this draft were proposed changes involving procedures used when evaluating semiautomatic and automatic zero-setting mechanisms. 

This proposed draft has not been sufficiently vetted yet. That draft was offered for use on a trial basis by NTEP 

laboratories when evaluating manufacturer’s replacement instruments that are scheduled to undergo NTEP 

evaluation. S ome manufacturers within the Sector have indicated that they may have instruments ready to be 

submitted to NTEP for evaluation.

NTEP laboratories have agreed to use the amended checklist in order to identify gaps or necessary changes within 

the draft. Feedback from evaluators who have used this amended checklist is needed so that the Sector can 

determine if the proposed changes need further development. Any input and additional comments that are available 

will be discussed.
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B3 

NTEP evaluator Mr. Jones, California Division of Measurement Standards, informed the Sector that there have not 

been any submissions of BCS Totalizers from manufacturers that could serve as a model unit to apply this amended 

checklist to on a trial basis.

Belt-conveyor scale manufacturer representatives from Thermo Fisher Scientific and Merrick Industries, Inc. 

informed the Sector that they anticipate submitting devices to NTEP for evaluation in the near future. T hese 

manufacturers stated that their devices should be appropriate models to be used to evaluate the draft procedures.

Conclusion:

The Sector agreed that upon the application of the new draft test procedures, a report would be made to the Sector

by the NTEP evaluator(s) detailing any gaps in the procedures and further amendments if necessary. The amended 

checklist will be applied to these instruments when they become available.

2. Sealable Parameters List for NTEP Evaluation 

Source:

NIST, OWM

Background/Discussion:

A list of BCS features and parameters that were identified by the Sector as those that should be protected by a form 

of security seal had been developed during the 2009 NTETC BCS Sector Meeting. The list has been forwarded to 

NTEP laboratories who have agreed to use this list during NTEP evaluation of BCS to determine if the list is 

sufficiently comprehensive. Feedback from NTEP evaluators using this amended checklist is requested so that 

sector members are able to determine if the list is sufficient. Any additional input and comments available from 

manufacturers and NTEP evaluators on the proposed changes will be discussed.

The Sector was informed that although the sealable parameters list developed during the 2009 NTETC BCS Sector 

Meeting is in the current NCWM Publication 14, there have not been any instruments submitted for evaluation 

under NTEP that provide the opportunity to compare this list to. 

Conclusion:

The Sector agreed that the list as developed at the 2009 NTETC BCS Sector Meeting will remain in NCWM 

Publication 14 in its current form, and will be updated as needed based on any gaps identified by NTEP evaluators.

3. Linearization Feature for BCS

Source:

NIST, OWM

Background/Discussion:

Manufacturers and service agents of belt-conveyor scales have voiced support for the use of electronic instruments 

equipped with a linearity correction feature (i.e., multiple point calibrations) to reduce span errors that deviate from 

a linear pattern. I t has been reported by some sector members that this practice may be in conflict with the 

prohibition of this type of feature by certain weights and measures regulatory authorities. Some sector members 

have asked for clarification from the National Institute of Standards and Technology (NIST), Office of Weights and 

Measures (OWM) on the use of this type of feature and whether it is (or should be) permitted in existing U.S. 

standards. The U.S. National Work Group (USNWG) on BCS has deliberated on the use of a linearization feature 

for enhancing the performance of belt-conveyor scale systems and considered whether there is a need to develop 

requirements within NIST Handbook 44 to address its use. T est procedures (including those used for type 

evaluation) are to be analyzed and further developed or amended as needed in order to verify that this feature will 

comply with the current NIST Handbook 44. Manufacturers at the 2011 NTETC BCS Sector Meeting agreed to 

participate in a work group formed to develop a draft of test procedures that could be submitted to the NTEP 

Committee as proposed changes within NCWM Publication 14. This work group will also consider the scope for

the application of any newly developed test procedures (i.e. whether the test procedures will be applied retroactively 

to devices that have already received NTEP approval). The work group includes the following members:
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B4 

• Mr. Bill Ripka, Thermo Fisher Scientific

• Mr. Peter Sirrico, Thayer Scale / Hyer Industries

• Mr. Lars Marmsater, Merrick Industries, Inc.

• Mr. Ian Burrell, Control Systems Technology Pty Ltd.

The work group agreed to continue work on developing test procedures through correspondence and offer a draft for 

review by the Sector. An update on any progress that has been made in this effort will be provided to the Sector. 

The Sector recognizes that linearization correction features may at this time be in use in some manufacturer’s 

devices. T he Sector also understands that manufacturers may take different approaches in the design of such 

features and that it would be impractical to write a single set of procedures to follow during type evaluation of 

different manufacturer’s devices.

Mr. Barton, NIST Technical Advisor suggested that a simple, generic statement may be all that is needed to provide 

the evaluator with the information necessary (e.g., a statement that would direct the evaluator to follow procedures 

that are provided by the manufacturer).

Mr. Marmsater, Merrick Industries, Inc. noted that many electronic components used in the construction of beltconveyor scale systems become obsolete very rapidly and this causes the manufacturer to redesign the instruments 

to accommodate necessary changes in design. H e questioned whether this will require that a r evaluation be 

performed at the time of these redesigns. M r. Truex, NTEP Administrator acknowledged that this could be a 

potential problem and that NTEP, and if necessary, NTEP Committee would properly address this issue.

Conclusion:

The Sector agreed that the same work group that originally took on the linearization feature project during the 

2011 NTETC BCS Sector Meeting will regroup and continue the work to produce a rough draft of procedures to be 

followed when evaluating the instruments ability to compensate for non-linear performance. This rough draft is to 

be completed by May 31, 2012, and then circulated to the Sector for review and comment.

4. Conveyor Belt Profiling

Source:

NIST, OWM

Background/Discussion:

This method of establishing a zer o-condition for a totalization operation enables the belt-conveyor scale to 

synchronize the application of an individual “tare” weight values associated with distinct segments of the belt to the 

movement of those belt segments over the scale portion of the conveyor. If this alternative to averaging the weight 

of segments of the belt carcass is used there is a potential need to establish a procedure to evaluate its effectiveness, 

to ensure that it functions as intended, and is maintained during operation of the BCS.

NIST OWM has received inquiries seeking guidance on whether this type of feature is permitted under U.S. 

standards. It is also being reported by some members of the USNWG BCS that some regulatory field officials will 

not issue an approval for devices equipped with this feature when it is not listed as a standard feature or an option on 

the NTEP Certificate of Conformance.

During the 2011 NTETC BCS Sector Meeting the Sector was asked to consider if there is a need for procedures to 

evaluate the effectiveness of belt profiling and to ensure that correct operation is maintained during totalization. A 

majority of Sector members voiced their opinion that this feature should receive some level of evaluation, and that at 

a minimum the ability to enable or disable any belt-profiling feature should be protected by some form of security 

seal. 

The Sector also concluded that it might be preferable to have the analysis and necessary action(s) for the 

consideration of belt profiling features taken on by the same work group formed under the previous agenda item. 
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B5 

The work group is comprised of the same members as the work group formed under the previous agenda item and 

includes:

• Mr. Bill Ripka, Thermo Fisher Scientific

• Mr. Peter Sirrico, Thayer Scale/Hyer Industries

• Mr. Lars Marmsater, Merrick Industries, Inc.

• Mr. Ian Burrell, Control Systems Technology Pty Ltd.

A draft of test procedures is expected to be made available for review by the Sector. An update on any progress 

made by the work group will be provided to the Sector. 

At the 2011 NTETC BCS Sector Meeting, the work group reported that no progress has been made on developing a 

draft for test procedures to evaluate belt profiling features.

Conclusion:

The Sector agreed that there is merit to incorporating guidance for NTEP evaluators by providing procedures for 

testing this feature. They agreed that the same group that originally took on the project will regroup and continue 

the work to produce a rough draft of procedures to be followed when evaluating a belt-profiling type of feature. 

This rough draft will be completed by May 31, 2012, and will be circulated to other sector members for review and 

comment.

NEW ITEMS

5. 2012 NIST Handbook 44 Changes 

Source:

NIST, OWM

Background/Discussion:

The proposed amendments were presented to the sector members and an explanation was provided for necessary 

changes that are being recommended.

Conclusion:

The 2012 edition of NIST Handbook 44 BCS code contains an amended paragraph N.3.1.3. After a review of the 

suggested changes, there were no opposing comments from the Sector. I t is recommended that NCWM 

Publication 14 be changed to reflect this amendment as shown below:

13. Field Test Procedure (page BCS-18)

Field Performance Test of the Belt-Conveyor Scale 

N.3.1.3. Check for Consistency of the Conveyor Belt Along Its Entire Length. – During a zeroload test with all operational no low-flow lockout disabled, the total change indicated in the totalizer 

during one any complete revolution of the belt shall not exceed the absolute value of 0.12 % of the 

minimum test totalized load. The end value of the zero-load test must meet the ± 0.06 % 

requirement (Test for Zero Stability).After a zero-load test with flow rate filtering disabled, 

the totalizer shall not change more than plus or minus (± 3 d) 3.0 scale divisions from its initial 

indication during one complete belt revolution.

Note: The end value of the zero-load test must meet the ± 0.06 % requirement referenced in 

the “Test for Zero Stability.”

6. Recommended Changes to Existing Language in NCWM Publication 14 

6.a. 9. Installation Requirements - paragraph numbering (page BCS-11) 

Source:

NIST, OWM

Background/Discussion:

The proposed amendments were presented to the sector and an explanation was provided for necessary changes that 

are being recommended.

Conclusion:

The Sector was asked to consider that the paragraph numbers within NCWM Publication 14 be changed to 

correspond with the previous renumbering of paragraphs in Section 9. T here were no opposing comments. 

Suggested amendments are shown below:

Code Reference: UR.2.2.1.

9.7.3. Pulleys, if used, must be properly protected from material 

build-up. 

Yes No N/A

9.7.4. If the tail pulley rides on a carriage, the guides must be 

protected against material build-up.

Yes No N/A

9.7.5. If the arrangements in (3) (9.7.3.) and (4) (9.7.4.) are used, 

then the bridle attaching the cable to the carriage must be 

designed such that the carriage will not become cocked in 

its guides or tracks.

Yes No N/A

6.b. Minimum Test Load (MTL) References

Source:

NIST, OWM

Background/Discussion:

When the value for MTL in NIST Handbook 44 [2.21. Belt-Conveyor Scale Systems], paragraph N.2.3.(a) was 

changed from 1000 s cale divisions to 800 s cale divisions in the 2005 e dition of NIST Handbook 44, not all 

corresponding values in NCWM Publication 14 were changed.

Conclusion:

The proposed amendments were presented to the Sector and explanations were provided for necessary changes that 

are being recommended. There were no opposing comments. To reconcile these NCWM Publication 14 references 

with current NIST Handbook 44 requirements, it is recommended that MTL references in NCWM Publication 14

Belt-Conveyor Scales Checklist be changed as shown, from 1000 d to 800 d in the following locations:

a. 6. Zero-Setting Mechanism (page BCS-7)

Code Reference: S.3.1. and S.3.1.1.

The zero-setting mechanism may be either a manual or automatic mechanism. In either case, the range 

of the zero-setting mechanism is limited to ± 2 % of the rated capacity of the scale. If a g reater 

adjustment is needed, the access to the adjustment must be through some security means. An audio or 

visual signal shall be given when the automatic and semi-automatic zero-setting mechanisms reach the 

limit of adjustment of the zero-setting mechanism. The zero-setting mechanism must be constructed 

such that the zero-setting operation is done only after a whole number of belt revolutions (a minimum 

of 3 revolutions or a time period equivalent to the time required to deliver 1000 800 d of load.) The 

completion of the zero-setting operation must be indicated. The low-flow lockout must be deactivated 

for this test.

7. Field Test Procedures for Reference Scales

7.a. Hopper Scales – 13. Field Test Procedure( page BCS – 17) 

Source:

NIST, OWM 

Background/Discussion:

The required minimum test weights of 10% of scale capacity as stated in NCWM Publication 14 does not 

correspond with the minimum test weight required in NIST Handbook 44 [2.20. Scales], Table 4 of 12.5 %. The 

Sector is asked if these values should be reconciled.

Sector members agreed that the minimum test weight amount of 10 % of scale capacity is in conflict with NIST 

Handbook 44 Scales Code, Table 4 where it is required that, for scales of greater than 3000 lb capacity the minimum 

test weight required is 12.5 % of scale capacity. The origin of the established value of 10 % is uncertain at this time. 

Mr. Barton, NIST Technical Advisor offered that the possible source for this value may have been from the stated 

value for minimum test weight in the NIST Handbook 44 [2.24.] Automatic Bulk Weighing Systems code where 

that type of device is required to be tested using 10 % of scale capacity as the minimum test weight.

The Sector originally agreed that this reference to 10 % minimum test weight required should be amended to 

coincide with the minimum test weight required under Table 4 – NIST Handbook 44 Scales Code (e.g., 12 % of 

scale capacity). Further discussion by the Sector disclosed that no requirement is present in NIST Handbook 44

BCS code to specify the capacity of a reference scale used and that the only specific requirement is that the scale 

used must produce weighments within 0.1 % accuracy.

Conclusion:

The amendments shown below were agreed upon by the Sector which specify that no more than three substitutions 

can be used during the testing of a hopper scale used a reference scale, and that the hopper scale be tested according 
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B10

to NIST Handbook 44 procedures. T he Sector recommends the changes as shown below be made in NCWM 

Publication 14. 

13. Field Test Procedure (page BCS-17)

Test of the Reference Scale

Hopper Scales

Hopper scales must be tested to the used capacity using a maximum of three substitution 

tests according to NIST Handbook 44 procedures. Test weights equal to a minimum of 10 % 

of scale capacity are needed; more test weight is recommended. The scale must be accurate to 

0.1 % and adjusted if necessary. 

Notice: After the 2012 NTETC BCS Sector Meeting, Mr. Barton, NIST Technical Advisor received feedback 

regarding concerns about this item and decision reached by the Sector. These concerns were specifically related to 

the deletion of a stated minimum required test weight and the apprehension that this type of scale may be tested 

using test weight in amounts that are smaller than what has been established as minimum. Mr. Ripka, Chair and Mr. 

Truex, NTEP Administrator were consulted, with a decision reached that since this is not a critical issue currently 

preventing a manufacturer from completing an NTEP evaluation, it would be best to hold as a carry-over item to be 

re-addressed at the next Sector meeting.

7.b. Railway Track Scales – 13. Field Test Procedure (page BCS-17)

Source:

NIST, OWM

Background/Discussion:

The Sector was asked to provide input regarding a recommendation that uncoupled in-motion railway scales used to 

establish reference weights for material tests be required to be tested in the mode (in-motion or statically) that will 

be used to determine the reference weights.

As written, this procedure does not prohibit weighing rail cars, uncoupled in-motion, to obtain reference weights for 

use during a material test when the railway scale’s accuracy has only been verified through static testing. 

Considering the substantial time and effort involved in testing an uncoupled in-motion railway scale, it is 

questionable whether the scale will be properly tested as an in-motion scale (when used as such) or if it will only 

have its accuracy verified through a statically performed test. 

The Sector was asked if the railway track scale is not tested as an in-motion scale, should it be accepted that the 

scale will be capable of producing reference weights of 0.1 % accuracy when the scale is used as an in-motion scale. 

Several sector members expressed their belief that reference weights can be obtained on an in-motion scale that has 

had its accuracy verified however; the weights should be obtained by static weighing only. This notion was based 

on the uncertainty whether in-motion weighing can consistently produce 0.1 % accuracy for all weighments.

Mr. Burrell, Control Systems Technology Pty Ltd. pointed out that to exclude the use of in-motion weighing from 

acceptable methods to obtain reference weights would be placing unfair limitations on technological advancements. 

He further stated that static type scales cannot be absolutely relied on to accurately produce weighments without 

error. Other sector members expressed the view that they are not aware of any tests being performed where 

reference weights are obtained by in-motion weighing.

Conclusion:

The Sector agreed that no action be taken on this recommendation, and that the current language in NCWM 

Publication 14 should not be amended.
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B11

13. Field Test Procedure (page BCS-17)

Test of the Reference Scale

Railway Track Scales

Because of the difficulties of obtaining adequate test weights or test cars to test railway track scales, 

the American Association of Railroads Committee simply recommends that the scales be tested the 

best way that can be arranged. The scale must be accurate to 0.1 % and adjusted if necessary.

Split-draft static-weighing is acceptable. Uncoupled in-motion weighing is permitted if it is done 

as a single draft. 

8. Time and Date Information Required on Recorded Indications

Source:

NIST, OWM

Background/Discussion:

The 2012 USNWG on BCS Meeting included discussion regarding paragraph S.1.4. in NIST Handbook 44 BCS 

code which requires that recorded indications include the date and time in addition to the initial and final totalizer 

reading and the unit of measurement. 

The statement of date and time however is non-specific in that there is no association made for the date and time 

record with the stage that the totalization process is in. 

This issue has also been included in the agenda for the NTETC BCS Sector Meeting; due to the reference to this 

NIST Handbook 44 requirement in NCWM Publication 14. The example of a r ecorded indication provided in 

NCWM Publication 14 (shown below) indicates a single, unspecified date and time. It may be reasonable to assume 

that because the total quantity is also provided on the recorded indication, that the date and time shown are 

associated with the final MWT reading.

2. Recording Element (page BCS-5)

Code Reference S.1.4. and G-S.5.2.2.:

2.3. The value of the scale division of the recording element shall be 

the same as that of the indicating element. The belt-conveyor 

scale system shall record the initial indication and the final 

indication on the MWT, the quantity delivered, the unit of 

measurement, (e.g., kilograms, tonnes, pounds, tons, etc.), the 

date, and time. This information shall be recorded for each 

delivery. The indicated and recorded weight values must agree to 

the nearest scale division.

Yes No N/A

2.4. All weight values shall be recorded as digital values. Yes No N/A

2.5. Information required on the ticket. Yes No N/A

NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

NTEP - B12

The Sector is asked to consider whether it is useful to include a time and date for the recorded indications of both the 

initial MWT reading and the final MWT reading. A dditionally, is there justification for providing enough 

information on the recorded indications to establish a span of time for the delivery of the total amount of material?

If it is determined that an amendment is needed to the NIST Handbook 44 requirement, it is recommended that the 

Sector draft the appropriate necessary changes to NCWM Publication 14. 

The Sector generally agreed that there is some justification for providing sufficient information on recorded 

indications to be able to determine the amount of time that has passed during a totalization of material and that this 

amount of time could easily be obtained by referencing a time and date indication on both the beginning and final 

totalization recorded indication. S ome sector members noted however, that recorded information that is already 

required to be indicated on flow chart recorders will provide that information. Other sector members agreed and 

added that it has been their experience that the flow chart recordings are always available for inspection as required.

Conclusion:

Considering the limited amount of space on many typical printed tickets that is available for the required recorded 

(printed) information, the Sector agreed not to support that additional information be required on the 

printed/recorded indications and that no changes to NCWM Publication 14 should be recommended with regard to 

this issue.

9. Short Conveyor Belt (Weigh-Belts) Systems

Source:

NIST, OWM

Background / Discussion:

The 2012 USNWG BCS Meeting Agenda include the reintroduction of language in NIST Handbook 44 under UR.2. 

regarding shorter belt systems that are designed and furnished by the manufacturer. This proposal would place 

language back into NIST Handbook 44 that had been stricken in 2001.

Although this language is not in the current edition of NIST Handbook 44, reference to NIST Handbook 44 in the 

current NCWM Publication 14 still includes this deleted wording. The Sector is asked to consider how to reconcile 

NCWM Publication 14 with references to requirements in NIST Handbook 44. 

Conclusion:

The Sector acknowledged there is on-going work regarding this issue being done by a sub-group of the U.S.

National Work Group on belt-conveyor scales, which may result in changes to future editions of NIST Handbook 

44. The Sector agreed however, that any references made in NCWM Publication 14 to requirements contained in 

NIST Handbook 44 should mirror the existing language in those requirements. They also agreed to recommend that 

the following amendments be made to NCWM Publication 14 to reflect existing language in NIST Handbook 44. 

9. Installation Requirements (page BCS-11)

Code Reference: UR.2.2.1.

9.7. Unless the scale is installed in a short conveyor designed and 

furnished by the scale manufacturer or built to the scale 

manufacturer's specifications, the conveyor shall comply with 

the following minimum requirements: The design and 

installation of the conveyor leading to and from the beltconveyor scale is critical with respect to scale performance. 

The conveyor can be horizontal or inclined, but if inclined, 

the angle shall be such that slippage of material along the belt 

does not occur. Installation shall be in accordance with the 

scale manufacturer’s instructions and the following:

Yes No N/A
NTEP Committee 2013 Final Report

Appendix B – NTETC 2012 Belt-Conveyor Scale Sector Meeting Summary

9.7.1. If the belt length is such that a take-up device is required, 

this device shall be of the counter-weighted type for either 

vertical or horizontal travel.

Yes No N/A

9.7.1.1. Indicate the Type: Vertical Horizontal

INTRODUCTION

The charge of the NTETC Grain Analyzer Sector is important in providing appropriate type evaluation criteria based 

on specifications, tolerances and technical requirements of NIST Handbook 44, Specifications, Tolerances, and 

Other Technical Requirements for Weight and Measuring Devices, Sections 1.10. General Code, 5.56. Grain 

Moisture Meters and 5.57. Near-Infrared Grain Analyzers. T he Sector’s recommendations are presented to the 

National Type Evaluation Program (NTEP) Committee each January for approval and inclusion in NCWM 

Publication 14, Technical Policy, Checklists, and Test Procedures for national type evaluation.

The Sector is also called upon occasionally for technical expertise in addressing difficult NIST Handbook 44 issues 

on the agenda of National Conference on Weights and Measures (NCWM) Specifications and Tolerances (S&T) 

Committee. S ector membership includes industry, NTEP laboratory representatives, technical advisors, and the 

NTEP Administrator. Meetings are held annually, or as needed and are open to all NCWM members and other 

registered parties.

Suggested revisions are shown in bold face print by striking out information to be deleted and underlining

information to be added. Requirements that are proposed to be nonretroactive are printed in bold faced italics. 

Note: It is the policy of the National Institute of Standards and Technology (NIST) to use metric units of measurement in 

all of its publications; however, recommendations received by NCWM technical committees and regional weights and 

measures associations have been printed in this publication as submitted. Therefore, the report may contain references in 

inch-pound units.

2. Report on NTEP Evaluations and Ongoing Calibration Program (OCP) (Phase II) Testing

Ms. Cathleen Brenner, Grain Inspection, Packers and Stockyards Administration (GIPSA), brought the Sector up to 

date on NTEP Evaluation (Phase I) activity. Renovation of the laboratory is nearly complete. The process of 

moving and installing the environmental chamber, air ovens, and other equipment into the new area will begin 
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C4 

shortly after Labor Day. Because of the renovations, the laboratory has been without an environmental chamber for 

over a year. Once the move is underway, the NTEP lab can begin accepting applications for Phase I testing.

Ms. Brenner also reported on the collection and analysis of Grain Moisture Meter OCP (Phase II) data on the 2011 

crop. For the 2012 harvest there are seven models enrolled in Phase II. (Perten Instruments elected not to continue 

model AM5100 in Phase II this year. Their CC for the AM5100 will expire in June 2013.) The manufacturers will 

be charged on the basis of six models because, using GAC2500-UGMA data, DICKEY-john can automatically back 

calculate calibrations to the GAC2500 without having to run samples on the GAC2500*. Phase II data collection for 

the 2012 harvest began in early August.

The seven meters:

1. Bruins Instruments – OmegAnalyzerG

2. DICKEY-john Corp. – GAC2000 (NTEP Version), GAC2100a and GAC2100b

3. DICKEY-john Corp. – GAC2500 (*See note above. Will not run samples on this model. )

4. DICKEY-john Corp. – GAC2500-UGMA

5. Foss North America – Infratec 1241

6. Perten Instruments Inc. – AM5200 and AM5200-A (The AM5200-A is UGMA Certified.)

7. The Steinlite Corporation – SL95

The 2012 Phase II enrollment cost to each manufacturer, based on 6 device types, is $8,750.

3. Review of OCP (Phase II) Performance Data

At the Sector’s August 2005 meeting it was agreed that comparative OCP data identifying the Official Meter and 

listing the average bias for each NTEP meter type should be available for annual review by the Sector. Accordingly, 

Ms. Brenner, GIPSA, presented data showing the performance of NTEP meters compared to the air oven. This data 

is based on the last three crop years (2009 - 2011) using calibrations updated for use during the 2012 harvest season. 

The 2009 - 2011 Grain Moisture Meter (GMM) Phase II comparison graphs may be viewed or downloaded for 

printing at the following web address:

http://ncwm.net/sites/default/files/meetings/grain_analyzer/2012/12_GMM_Bias.pdf

Ms. Brenner pointed out that the data identified as the “Official Meter” is based on the GAC 2100. The Official 

Meter data is in blue for all the charts. A randomized assignment of colors was used for the individual 

manufacturers, so the violet color identified as “Meter 1”on the charts represents a different manufacturer on each 

chart; “Meter 2” is a different manufacturer on each chart; etc.

Overall, the performance of the meters looked good for all the grains except Long Grain Rough Rice. It had the most 

variation between meters. 

The Sector was reminded that effective September 1, 2012, [Editor’s note: The effective date was subsequently 

delayed to September 10, 2012.] the DICKEY-john GAC2100 will no longer be the Official Meter for the following 

four grains: corn, soybeans, sunflower, and sorghum. These four grains will have official calibrations from the two 

Official Meters, the GAC2500-UGMA, and the AM5200-A. The remaining grains are scheduled to switch to the 

GAC2500-UGMA, and the AM5200-A for Official Inspection on May1, 2013.

Discussions have been held at GIPSA as to how comparison data might be displayed next year since the Official 

Meter is changing. Present thinking is that meters will be randomly identified as Meter 1, Meter 2, Meter 3, etc. for 

each grain. The Official Meters will be included in that random assignment once they have accumulated three years 

of data.

4. Amend Table S.2.5. of §5.56.(a) in NIST Handbook 44

Source:

NTETC Grain Analyzer Sector

Purpose:

Delete “remotely” from the second paragraph of Category 3 requirements that begins, “When accessed remotely ...” 

to make it clear that the requirements of Category 3 apply whether accessed manually using the keyboard or 

accessed by remote means, and add the modified second paragraph of Category 3 requirements to Categories 3a and 

3b to make it clear that these requirements apply to all the subcategories of Category 3. 
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C6 

Item Under Consideration:

Table S.2.5. 

Categories of Device and Methods of Sealing

Categories of Device Methods of Sealing

Category 1: No remote configuration capability. Seal by physical seal or two event counters: one for 

calibration parameters (000 to 999) and one for configuration 

parameters (000 to 999). If equipped with event counters, the 

device must be capable of displaying, or printing through the 

device or through another on-site device, the contents of the 

counters.

Category 2: Remote configuration capability, but 

access is controlled by physical hardware.

A device shall clearly indicate that it is in the remote 

configuration mode and shall not be capable of 

operating in the measure mode while enabled for remote 

configuration.

The hardware enabling access for remote communication must 

be at the device and sealed using a physical seal or two event 

counters: one for calibration parameters (000 to 999) and one 

for configuration parameters (000 to 999). If equipped with 

event counters, the device must be capable of displaying, or 

printing through the device or through another on-site device, 

the contents of the counters.

Category 3: Remote configuration capability access 

may be unlimited or controlled through a software 

switch (e.g., password).

When accessed remotely for the purpose of modifying 

sealable parameters, the device shall clearly indicate 

that it is in the configuration mode and shall not be 

capable of operating in the measuring mode.

An event logger is required in the device; it must include an 

event counter (000 to 999), the parameter ID, the date and time 

of the change, and the new value of the parameter (for 

calibration changes consisting of multiple constants, the 

calibration version number may be used rather than the 

calibration constants). A printed copy of the information must 

be available through the device or through another on-site 

device. The event logger shall have a capacity to retain 

records equal to twenty-five (25) times the number of sealable 

parameters in the device, but not more than 1000 records are 

required. (Note: Does not require 1000 changes to be stored 

for each parameter.)

Category 3a: No remote capability, but operator is able 

to make changes that affect the metrological integrity of 

the device (e.g., slope, bias, etc.) in normal operation.

When accessed for the purpose of modifying sealable 

parameters, the device shall clearly indicate that it is in 

the configuration mode and shall not be capable of 

operating in the measuring mode.

Same as Category 3

Category 3b: No remote capability, but access to 

metrological parameters is controlled through a 

software switch (e.g., password).

When accessed for the purpose of modifying sealable 

parameters, the device shall clearly indicate that it is in 

the configuration mode and shall not be capable of 

operating in the measuring mode.

Same as Category 3

[Nonretroactive as of January 1, 1999] 

[*Nonretroactive as of January 1, 20XX]

(Amended 1998 and 201X) 

Note: Zero-setting and test point adjustments are considered to affect metrological characteristics and must be sealed.

(Added 1993) (Amended 1995 and 1997)
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C7 

Background/Discussion: 

All of the GMMs in Categories 3, 3a, and 3c of Table S.2.5. use an electronic method of sealing, and most of them 

also offer access to the configuration mode thorough a k eyboard entered password. I n this mode, sealable 

parameters can also be changed locally through the keyboard. Category 3 of Table S.2.5. currently includes the 

following requirement:

When accessed remotely for the purpose of modifying sealable parameters, the device shall clearly 

indicate that it is in the configuration mode and shall not be capable of operating in the measuring mode.

At its 2011 Grain Analyzer Sector Meeting the Sector agreed by consensus that the following changes to 

Table S.2.5. of §5.56.(a) of NIST Handbook 44 should be forwarded to the S&T Committee for consideration:

• Add a note to Table S.2.5. to recognize the expanded scope of “remote capability”. 

• Delete “remotely” from the second paragraph of Category 3 requirements that begins, “When 

accessed remotely ...” to make it clear that the requirements of Category 3 apply whether 

accessed manually using the keyboard or accessed by remote means.

• Add the modified second paragraph of Category 3 requirements to Categories 3a and 3b to make 

it clear that these requirements apply to all the subcategories of Category 3.

At the suggestion of National Institute of Standards Technology (NIST), Office of Weights and Measures (OWM), 

the Table S.2.5. changes approved by the Sector in 2011 h ave been separated into two independent items: on e 

dealing with the changes to Category 3 and its subcategories (as shown in Item Under Consideration) and one 

dealing with the modification of the definition of remote configuration capability appearing in Appendix D of NIST 

Handbook 44 to recognize the expanded scope of “remote capability.” This independence insures that one item will 

not hold up the other from consideration.

Contingent upon approval of the Item Under Consideration by NCWM, a number of related changes will be required 

to both the GMM Chapter and the Near Infrared (NIR) Grain Analyzer Chapter of NCWM Publication 14. These 

changes are shown in Items 4(a), 4(b), and 4(c) following:

[Changes shown below are contingent upon acceptance of Item Under Consideration]

Table S.2.5. Categories of Device and Methods of Sealing

Categories of Device Method of Sealing

Category 1: No remote configuration capability Seal by physical seal or two event counters: one for 

calibration parameters (000 to 999) and one for 

configuration parameters (000 to 999.) If equipped with 

event counters, the device must be capable of displaying, 

or printing through the device or through another on-site 

device, the contents of the counters.

Category 2: Remote configuration capability, but 

access is controlled by physical 

hardware.

Device shall clearly indicate that it is in 

the remote configuration mode and 

shall not be capable of operating in the 

measure mode while enabled for remote 

configuration.

The hardware enabling access for remote 

communication must be at the device and sealed using a 

physical seal or two event counters; one for calibration 

parameters (000 to 999) and one for configuration 

parameters (000 to 999.) If equipped with event 

counters, the device must be capable of displaying, or

printing through the device or through another on-site 

device, the contents of the counters.

parameter (for calibration changes consisting of multiple 

constants, the calibration version number may be used 

rather than the calibration constants.) A printed copy of 

the information must be available through the device or 

through another on-site device. The event logger shall 

have a cap acity to retain records equal to twenty-five 

(25) times the number of sealable parameters in the 

device, but not more than 1000 r ecords are required. 

(Note: Does not require 1000 changes to be stored for 

each parameter.)

4.c. Proposed Changes to the Checklist of the NIR Grain Analyzer Chapter of NCWM Publication 14

Near Infrared (NIR) Grain Analyzers use an electronic method of sealing similar to those of GMMs, and most 

of them also offer access to the configuration mode thorough a keyboard entered password. I n this mode, 

sealable parameters can be changed locally through the keyboard. At the 2011 NTETC Graina Analyzer Sector 

Meeting, the Sector agreed that contingent upon acceptance of Item Under Consideration the NIR Check List of 

NCWM Publication 14 should be modified to delete “remotely” from §4 Design of NIR Analyzers, 

paragraph 4.9.16 as shown below. 

[The change shown below is contingent upon acceptance of Item Under Consideration]

4.9.16.

If a measurement is in process when the device is accessed remotely

for the purpose of modifying sealable parameters, the measurement is 

either:

audit trail information: 

 

Conclusion:

The Sector agreed by consensus to accept the Item Under Consideration and recommended that a Form 15 be 

drafted for forwarding this item to the S&T Committee for consideration. M r. Truex, NTEP Administrator, 

indicated that Items 4.a., 4.b., and 4.c. would automatically be considered by the NTETC upon approval of the Item 

Under Consideration by the NCWM.

5. Modify the Definition of Remote Configuration Capability Appearing in Appendix D of NIST 

Handbook 44 to Recognize the Expanded Scope of “Remote Configuration Capability” 

Source:

NTETC Grain Analyzer Sector

Purpose:

Table S.2.5. Categories of Device and Methods of Sealing that appears in §5.56.(a) of NIST Handbook 44 lists 

acceptable methods of sealing for various categories of GMMs. When the Sector first recommended adding the 

table to NIST Handbook 44 at their September 1996 meeting, the concept of making a change to a GMM from a 

remote site involved information “ ...sent by to the device by modem (or computer).” In 2011 this concept has 

expanded to include the ability of the measuring device to accept new or revised sealable parameters from a memory 

chip (e.g., an SD Memory Card that may or may not itself be necessary to the operation of the device), external 

computer, network, or other device plugged into a mating port (e.g., Universal Serial Bus [USB] port) on the 

measuring device or connected wirelessly to the measuring device. T he changes proposed in Item Under 

Consideration expand the scope of “remote configuration capability” to cover instances where the “other device” 

may be necessary to the operation of the weighing or measuring device or which may be considered a permanent 

part of that device. 

Item Under Consideration:

remote configuration capability. – The ability to adjust a weighing or measuring device or change its sealable 

parameters from or through some other device that is not may or may not itself be necessary to the operation

of the weighing or measuring device or is not may or may not be a permanent part of that device.[2.20., 2.21., 

2.24., 3.30., 3.37., 5.56.(a)]

(Added 1993) (Amended 20XX) 

Background/Discussion: 

Two common types of removable data storage devices are the USB flash drive and the Secure Digital (SD) memory 

card. A USB flash drive is a data storage device that includes flash memory with an integrated USB interface. USB 

flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. A SD card is a 

non-volatile memory card format originally designed for use in portable devices. The SD standard is maintained by 

the SD Card Association.

Removable digital storage devices can be used in GMMs as either “data transfer” devices which are not necessary to 

the operation of the GMM or as “data storage devices” which are necessary to the operation of the GMM. 

A USB flash drive is most likely to be used as a “data transfer” device. In a typical “data transfer” application, the 

USB flash drive is first connected to a co mputer with access to the web. T he computer visits the GMM 

manufacturer’s web site and downloads the latest grain calibrations that are then stored in the USB flash drive. The 

USB flash drive is removed from the computer and plugged into a USB port on the GMM. The GMM is put into 

“remote configuration” mode to copy the new grain calibration data into the GMM’s internal memory. When the 

GMM has been returned to normal operating (measuring) mode the USB flash drive can be removed from the 

GMM.

Although an SD memory card could also be used as a “data transfer device” it is more likely to be used as a “data 

storage device”. In a typical “data storage device” application, the SD memory card stores the grain calibrations 

used on the GMM. The SD memory card must be plugged into an SD memory card connector on a GMM circuit 

card for the GMM to operate in measuring mode. To install new grain calibrations the GMM must be turned “off” 

or put into a mode in which the SD memory card can be safely removed. T he SD memory card can either be 

replaced with an SD memory card that has been programmed with the new grain calibrations or the original SD 

memory card can be re-programmed with the new grain calibrations in much the same way as that described in the 

preceding paragraph to copy new grain calibrations into a USB flash drive. In either case, the SD memory card 

containing the new calibrations must be installed in the GMM for the GMM to operate in measuring mode. In that 

regard, the SD memory card ) can be considered a “permanent part” of the GMM in that the GMM cannot operate 

without it. 

Note: In the above example “SD memory card” could be any removable flash memory card such as the Secure 

Digital Standard-Capacity, the Secure Digital High-Capacity, the Secure Digital eXtended-Capacity, and the Secure 

Digital Input/Output, which combines input/output functions with data storage. These come in three form factors: 

the original size, the “mini” size, and the “micro” size. “Memory Stick” is a removable flash memory card format, 

launched by Sony in 1998, and is also used in general to describe the whole family of Memory Sticks. In addition to 

the original Memory Stick, this family includes the Memory Stick PRO, the Memory Stick Duo, the Memory Stick 

PRO Duo, the Memory Stick Micro, and the Memory Stick PRO-HG.

Conclusion:

The Sector agreed by consensus to accept the Item Under Consideration and recommended that a Form 15 be 

drafted for forwarding this item to the S&T Committee for consideration. 

6. Test Weight per Bushel Acceptance and Maintenance Tolerances

Source:

Mr. Jeffrey D. Adkisson, Grain and Feed Association of Illinois

Purpose:

Due to problems cited in the grain and feed industry, review and make any needed changes to the test weight per 

bushel tolerances in NIST Handbook 44, Section 5.56.(a).
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C11

Item Under Consideration:

Re-form a task group to study the test weight per bushel measurement system to include issues with field inspection 

and grain moisture meters and provide the Sector with recommendations for any needed changes to the test weight 

per bushel tolerances in NIST Handbook 44, Section 5.56.(a).

Background/Discussion:

This is a carryover from the Sector’s 2011 meeting. Mr. Adkisson, Grain and Feed Association of Illinois, cited 

problems his industry is having regarding Test Weight (TW) per bushel. GMMs that have failed TW during field 

inspection are sent to the manufacturer for repair. W hen the meters are returned, the reports indicate that no 

problems have been found. There are also situations where a meter has failed TW. When the state inspector 

subsequently tested the elevator’s quart kettle it matched the meter, but it didn’t match the state inspector’s sample. 

This is particularly frustrating for the country elevators in Illinois that are using the GMM TW only as a screening 

tool. 

At the Sector’s August 2011 meeting, a task group was formed to investigate the whole TW system with the goal of 

defining procedures that would improve TW both for the user and for the inspection system. Past data obtained by 

the Sector had indicated that the existing tolerances were reasonable. It was felt that increasing TW tolerances 

would only cover up the problems. W hat was needed was an investigation of the whole system of calibrating 

meters, then translating that calibration into the field, and then keeping it that way. 

Dr. Charles R. Hurburgh, Jr., Iowa State University, agreed to head the task group. Other TW Task Group members 

included:

• Mr. Jeffery Adkisson – Grain and Feed Association of Illinois

• Ms. Diane Lee – NIST, OWM

• Ms. Cassie Eigenmann – DICKEY-john Corporation

• Mr. Ivan Hankins – Iowa Department of Agriculture/Weights and Measures

• Mr. Tim Kaeding – Perten Instruments, Inc.

• Mr. Karl Cunningham – Illinois Department of Agriculture

Further action on the issue of tolerances was postponed until the TW Task Group was able to recommend 

appropriate action.

Earlier this year the TW Task Group developed the following list of Action Items:

• Survey the grain industry as to the frequency of discounting each of the major grains (wheat, corn, and 

soybeans) for test weight, and within those discounted the frequency of use of the meter test weight versus 

the cup-bucket test weight.

• Survey the industry for comparative data between meters and an Official GIPSA agency on the same 

samples.

• Develop a draft procedure for sample selection and pre-qualification

Dr. Hurburgh reported that discounting for low TW was not an issue in either 2010 or 2011. TWs for corn were so 

high that discounting was not an issue. Within Iowa most grain elevators were using the TW reported by their 

GMM. Only a few were using the standard quart kettle method. This is likely to change in the 2012 harvest as low 

TWs are likely to be more common. Also, there may not be as much TW increase in drying as would normally be 

expected. TW may come up again as a discount factor.

Same sample TW data has not been collected comparing grain elevator GMMs with an Official GIPSA agency. 

Dr. Hurburgh explained that this information should be relatively easy to obtain, because in almost every case when 

a train is officially graded the samples are run at the grain elevator first. Since last year’s Sector meeting, the rapid 

acceptance of the new UGMA GMMs as Official Meters for corn, soybeans, sunflowers, and grain sorghum (with 

the remaining grains scheduled to switch to UGMA GMMs for Official Inspection on May1, 2013), has altered 

some of the issues. T he new technology not only provides a b etter moisture measurement, but a b etter TW 

measurement as well.
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C12

The remaining action item that the task group believed was necessary was a p rocedure for pre-qualifying TW 

samples as being good predictors for the TW function as well as moisture function. Most States pre-screen moisture 

samples to get the outliers out of the system. That pre-qualification would have to be expanded if TW is to be 

actively used to reject meters on the basis of TW.

Dr. Hurburgh recommended that the Sector not adjust TW tolerances at this time, because the system is rapidly 

changing over to the new technology which is going to result in the improvement in TW readings. The problem 

should resolve itself as older instruments are retired.

Mr. Karl Cunningham, Illinois Dept of Agriculture, informed the Sector that Illinois’s TW rejection rate has gone 

down in the last two years. He has no problem with TW on the meters in his laboratory and doesn’t think the 

present tolerances are a problem. Many of the field problems may be due to rough handling of the meters during 

shipping. Mr. Cunningham advises elevators who have to have their devices worked on to take them to the 

manufacturer’s service department themselves if at all possible.

Mr. Tim Kaeding, Perten Instruments, suggested that there might be value in expanding the Phase II OCP grain 

moisture comparison charts to include TW. Dr. Hurburgh recommended that a TW comparison chart showing the 

spread of TW measurements for individual meters against the corresponding official quart kettle TW measurements 

would address the tolerance issue, whereas a bias plot would not. He suggested plotting meter TWs on the x-axis 

and quart kettle results on the y-axis. A best-fit line could be drawn for each meter.

The Sector agreed that TW comparison charts should be prepared for the three grains which are most likely to be 

subject to discounts on the basis of TW: Corn and two wheat classes. The wheat classes selected were: Hard Red 

Winter and Soft Red Winter. Manufacturer approval is required for NTEP Phase II TW performance data to be 

released for publication even if individual instruments are not identified. T he two meter manufacturers present 

indicated that they would approve the release of this data. Permission would have to be obtained from the other 

manufacturers. 

Conclusion: 

Ms. Brenner will send letters, to all GMM manufacturers outlining the way TW data will be displayed for each 

meter for corn and two classes of wheat. The letters will request formal approval for release of NTEP Phase II TW 

performance data. Meters will NOT be identified.

The Sector agreed to postpone further action on changing TW tolerances until more information was available. 

7. Report on International Organization of Legal Metrology (OIML) TC 17/SC 1 R 59 Moisture Meters 

for Cereal Grains and Oilseeds

Background/Discussion:

This item was included on the Sector’s agenda to provide a summary of the activities of OIML TC 17/SC 1. The 

Co-Secretariats (China and the United States) are working closely with an International Work Group to revise OIML 

Recommendation R 59 Moisture Meters for Cereal Grains and Oilseeds. The 5 Committee Draft (CD) of OIML 

R 59, revised to comply with OIML’s Guide Format for OIML Recommendations and to incorporate tests for the 

recommended disturbances of OIML Document D 11, General Requirements for Electronic Measuring 

Instruments, was distributed to the Subcommittee in February 2009. Comments to R 59 5 CD were received from 

10 countries including the United States. A preliminary R 59 6 CD addressing those comments was prepared for 

discussion at the September 2010 TC 17/SC 1 meeting in Orlando, Florida. Per discussions at that meeting, 

Germany submitted suggestions for additional software requirements that will be included in the final draft of R 59 

6 CD.

Ms. Diane Lee, NIST, OWM, reported that the preliminary 6 CD will have to be revised to address the comments 

received at the September 2010 TC 17/S 1 meeting and to incorporate Germany’s additional software requirements. 

The final draft of 6 CD will then be circulated to the TC members for comment and a possible vote. The earliest 

anticipated date for the final draft of 6 CD is the spring of 2013.

8. Update on Efforts to Establish Recognized Traceability under the International Committee of Weights 

and Measures (CIPM) Mutual Recognition Agreement (MRA) for Moisture in Grain Measurements

Background/Discussion: 

At the 2011 NTETC Grain Analyzer Sector Meeting, Ms. Lee, NIST, OWM, reported that there is a proposal on the 

international front to do a study of moisture measurement methods with the apparent purpose of establishing a 

universal standard method “internationally accepted by competent authorities in the field of moisture measurements 

in grains and cereal.” During the September 2010, TC 17/SC 1 meeting Mr. Jean–Francois Magana, International 

Bureau of Legal Metrology (BIML), gave an overview of a discussion paper titled, Efforts to Establish Recognized 

Traceability Under the International Committee of Weights and Measures (CIPM) Mutual Recognition Arrangement 

(MRA) for ‘moisture-in-grain’ measurements.” This document discusses National Measurement Institutes having 

their measurement capabilities internationally recognized for moisture. It also discusses key comparisons for 

moisture, and the use of ISO 712, Cereals and cereal products -- Determination of moisture content -- Reference 

method (not applicable to maize and pulses). In November 2011, the United States and China received a notice for a 

proposal for a new project within TC 17/SC 1 to create a new OIML recommendation to define the measurand 

“moisture mass fraction in grain” by a globally recognized measurement method. In the United States, NIST, OWM

and U.S. Department of Agriculture (USDA), with management from both agencies, held a co nference call to 

discuss technical issues concerning establishing a globally recognized reference method. After which the United 

States and China responded and elaborated on technical and economic issues. A copy of the response is shown 

below: 

“....On the matter of International Committee of Legal Metrology (CIML) approval of this proposed 

project, we feel that the draft letter that you have prepared does not provide enough information to CIML 

Members for them to make an informed decision. We have consulted with members of the United States

“mirror” committee, USDA, GIPSA, and they have informed us that studies of the type being proposed 

here have already been carried out in the 1980s, and so it is questionable whether it makes sense to try and 

‘reinvent the wheel’ with this project. The results of the studies have shown that this issue involves not 

only the technical feasibility of developing an acceptable global measurement method for moisture mass 

fraction in grains (i.e., defining the measurand), but equally (if not more) importantly involves the 

economic (and hence political) feasibility of developing and implementing a single global standard. The 

anticipated global costs associated with making the changes that this project could lead to are staggering, 

and would quite likely not be acceptable to the stakeholder communities.

Therefore, we believe that the initial letter to the CIML Members should ask not only the technical 

questions that you have posed (and perhaps others as well), but should also ask what the national agencies 

and customers in the different Member States have to say about the idea of possibly changing the test 

method in their country to accommodate a single global standard measurement method. We feel that such 

information should be obtained (through a formal survey, not in the informal way posed in your draft letter) 

and then shared with the CIML Members before asking them to vote on approval of this proposal. We 

would be happy to assist you in the re-drafting of your letter and preparation of the survey.

Elaborating on what we see as the technical issues, it is well recognized that no universal method can be 

used for all grains and seeds. The main steps of the experimental procedure, for example, pre-drying, 

grinding, drying time, and temperature, generally differ from one grain type to the next as dictated by 

physical and chemical composition.. Thus, a cr itical study of the procedure would be required for each 

grain type. A wide range of grain moisture reference methods are used by major grain exporting and 

importing countries. Grain moisture reference methods were adopted decades ago and are well established 

within these countries. m Comparison studies have shown that no methods are identical and that differences 

can be significant between some methods. The extent to which the methods agree will vary by grain type.

Elaborating on what we see as the economic issues, it is challenging to identify economic benefits of 

moving to an international moisture reference method. Persuasive arguments have been presented that 

market prices have already adjusted to reflect differences in grain moisture reference results. It is easier, 

and fairly daunting, to predict costs associated with making a change to grain moisture reference methods 

for an individual country. It would be necessary to develop new moisture meter calibration coefficients for

each grain type. In some cases, grain drying costs could be increased in order to meet moisture 

specifications. Perhaps most significantly, price structures would need to be modified...”

This was discussed further at the OIML Presidential Council meeting March 5 - 7, 2012, and it was included in the 

meeting minutes that there was insufficient evidence that the latest developments described in the NIST, OWM 

newsletter article would result in an instrument/procedure that could be used as an international standard for 

moisture mass fraction of grain measurements. 

In a conversation with Mr. Patoray, BIML Director, Dr. Erhlich, NIST, OWM was informed that the OIML is no 

longer pursuing the new project to create an OIML recommendation to define the measurand “moisture mass 

fraction in grain.” 

Subsequently, the United States and China, secretariats of OIML Technical Committee (TC) 17/Technical 

Subcommittee (SC) 1, received a document from Ms. Stephanie Bell of the National Physical Laboratory in the UK 

with reference to a proposed research topic to submit to the current call of the European Metrology Research 

Program (EMRP) to address the need for a more effective metrology infrastructure for measurements of moisture in 

materials. The United States and China responded including excerpts from the response provided for the OIML 

Proposal to create a new OIML recommendation to define the measurand “moisture mass fraction in grain”. OIML 

TC 17/SC 1 was not listed in support of these efforts.

Ms. Diane Lee (NIST, OWM) reported that she is developing an article on grain moisture measurements in the 

United States that has been reviewed by Dr. Richard Pierce of USDA, GIPSA. This article provides information on 

U.S. air-oven reference methods to include historical information and a summary of the various test methods used 

for different grains and types of commodities. This article may also serve to provide the international community 

with information on the air-oven reference test methods used in the United States. 

9. Report on OIML TC 17/SC 8 Protein Measuring Instruments for Cereal Grain and Oil Seeds

Background/Discussion: 

This item was included on the Sector’s agenda to provide a s ummary of the activities of OIML TC 17/SC 8. 

Subcommittee SC 8 was formed to study the issues and write a working draft document Measuring Instruments for 

Protein Determination in Grains. Australia is the Secretariat for this subcommittee. A TC 17/SC 8 meeting was 

hosted by NIST, OWM in September 2007 to discuss the 2 CD. Discussions on 2 CD dealt mostly with Maximum 

Permissible Errors and harmonization of the TC 17/SC 8 Recommendation for protein with the TC 17/SC 1 

Recommendation for moisture. The Secretariat distributed a 2 CD of the document in February 2010. A meeting of 

TC 17/SC 8 was held September 2010 i n Orlando, Florida. At the September meeting, comments to the 

Recommendation on Protein Measuring Instruments for Cereal Grain and Oil Seeds 2 CD were reviewed. It was 

agreed at this meeting that two instruments will be submitted for OIML type approval.

Ms. Diane Lee (NIST, OWM) reported that the 3 CD of the OIML Recommendation on Protein was distributed to 

members of the USNWG via e-mail on July 3, 2012. Comments to the 3 CD were requested by September 8, 2012. 

The 3CD incorporates the changes to 2CD that were agreed to at the 2010 TC 17/SC 8 meeting in Orlando, Florida. 

Changes were also made to the 3 CD to harmonize some section with OIML R 59 and include requirements of 

OIML D 11. Further discuss is needed to address wheather or not all of the OIML D11 requirements that were 

added to the 3CD are necessary for protein analyzers. In response to a question, “How many revisions are 

associated with OIML Recommendations?” Ms. Lee responded that typically, if comments to an OIML 

Recommendation can be resolved by voice or e-mail, the next version of the Recommendation could be forwarded 

for to the participating member countries for a Vote.

10. Item 356-1 Printed Ticket User Requirements - Update

Source:

Grain and Feed Association of Illinois (2012)

Purpose:

Change the mandatory printing of tickets from grain moisture meters to an “on demand at the time of transaction” 

printing and remove the requirement of printing the calibration version identification. Note that the S&T Committee 

did not agree with proposed removal of the requirement to print the calibration version identification; this position is 

reflected in the version of the proposal currently under consideration by the Committee.

Item Under Consideration:

Amend NIST Handbook 44, Grain Moisture Meter Code 5.56.(a) as follows: 

UR.3.4. Printed Tickets. 

(b) The customer shall be given a printed ticket at the time of the transaction or as otherwise specified 

by the customer. The printed ticket shall include the date, grain type, grain moisture results, and test 

weight per bushel, and calibration version identification. The ticket information shall be generated by 

the grain moisture meter system.

(Amended 1993, 1995, and 2003, and 20XX) 

Background: 

According to the submitter, the user requirement to provide a printed ticket for every single load is unrealistic in the 

country elevator industry. Traffic patterns at country elevators do not lend themselves to providing a printed ticket 

to all customers and customers really don’t want them. As the speed and capacity increases in the industry, 

outbound scales are being located at a distance from the inbound scale and the scale house where the moisture tester 

is located to alleviate traffic bottlenecks. When the outbound scale is located away from where the ticket is printed, 

the truck driver must circle back around to pick up the ticket, thus, causing logistical problems. In addition, since 

meters are sealed, inspected and required to have the correct calibration, there is no need for the calibration version 

identification to be printed on the ticket. Also, most customers are not going to know if it is the correct calibration 

version identification or not. There have been problems getting the information from the grain moisture meter to the 

grain accounting system – especially the calibration version identification. Some grain accounting systems have to 

be “hard coded” for calibration version identification which must be changed whenever the calibration changes. The 

change will be at an added cost for the industry. 

When a consumer pays at a gas pump, they have the option of a receipt on demand at the time of transaction or not 

receiving a receipt. There would be a cost savings to moisture meter users as they would save on paper and filing 

space, and in the situation where the calibration version identification is “hard coded,” there will be a cost savings of 

the expense to have the grain accounting software provider make those changes. 

Since moisture meters are capable of printing the ticket, some would argue that they should just go ahead and print 

them and provide them to the customer. In addition, the requirement does not say when the ticket shall be given to 

the customer; thus, the printed tickets could be saved for weeks, months, or even years in case the customer had a 

concern at some point. Printing the calibration version identification ensures the correct calibration is being used. 

The submitter proposed amendments to paragraph UR.3.4. Printed Tickets as follows: 

UR.3.4. Printed Tickets.

(b) The customer shall be given a printed ticket on demand at the time of the transaction showing the 

date, grain type, grain moisture results, and test weight per bushel, and calibration version 

identification. The ticket information shall be generated by the grain moisture meter system.

NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C16

At the 2011 Central Weights and Measures Association (CWMA) Interim Meeting some jurisdictions opposed the 

proposal citing that it is a fundamental element of a point of sale transaction that there is either a witness to the 

transaction or that a receipt is made available. Others supported the item and recognized that many customers refuse 

to take the printed tickets. The CWMA believes that the calibration version identification is not necessary on the 

ticket since most jurisdictions are already verifying the calibrations version when the device is inspected. T his 

proposal is not eliminating the opportunity for the seller to obtain a printed ticket. The CWMA forwarded the item 

to NCWM, recommending it as a Voting Item. 

At the 2011 Western Weights and Measures Association (WWMA) Annual Meeting, the Committee heard no 

comments on this item. The WWMA amended the proposal to make the language consistent with other codes such 

as 3.32. LPG and Anhydrous Ammonia Liquid-Measuring Devices Code paragraph UR.2.6. Ticket Printer: 

Customer Tickets. The WWMA forwarded the modified version below to NCWM, recommending it as a Voting 

Item. 

UR.3.4. Printed Tickets. 

(b) The customer shall be given a printed ticket showing at the time of the transaction or as otherwise 

specified by the customer. The printed ticket shall include the date, grain type, grain moisture 

results, and test weight per bushel, and calibration version identification. The ticket information

shall be generated by the grain moisture meter system. 

(Amended 1993, 1995, and 2003, and 20XX) 

At the 2011 Northeastern Weights and Measures Association (NEWMA) Interim Meeting there were no comments. 

Deferring to the expertise of the NTETC Grain Analyzer Sector, NEWMA forwarded the item to NCWM, 

recommending it as a Developing Item. 

At the 2011 Southern Weights and Measures Association (SWMA) Annual Meeting, Ms. Butcher, NIST Technical 

Advisor, noted that the proposed language submitted was slightly different from that discussed by the NTETC Grain 

Analyzer Sector and provided a summary corresponding to this item prepared by Ms. Lee, Grain Analyzer Sector 

Technical Advisor. Ms. Butcher also pointed out that WWMA proposed alternate language that is consistent with 

printed tickets requirements in other codes. The SWMA agreed that the customer should be given the option of 

receiving a printed ticket from a transaction and that the proposed changes would clarify the responsibility of the 

device user. The SWMA preferred the option forwarded by WWMA since it mirrors existing language in other 

NIST Handbook 44 codes. T he SWMA forwarded the item to NCWM, recommending it as a V oting Item as 

revised by WWMA. 

At the 2012 NCWM Interim Meeting, the S&T Committee received comments in support of the alternative language 

submitted by the WWMA. NIST, OWM reported that the proposed language submitted to the regional weights and 

measures associations was different from that agreed to by the Grain Analyzer Sector at its August 2011 meeting. 

The Grain Analyzer Sector had specifically opposed deleting the phrase “calibration version identification.” NIST, 

OWM also noted that not all grain moisture meters are Category 3 devices; consequently, calibration version 

identification information is a critical component on the printed receipt to reconstruct the basis for a sale and help 

officials to resolve complaints. 

The Committee agreed that the version proposed by WWMA and SWMA was preferable since it mirrors similar 

language in other NIST Handbook 44 Codes. The Committee also agreed that, given the Grain Analyzer Sector’s 

opposition to deleting the reference to “calibration version identification,” this phrase should be retained in the 

paragraph. T he Committee presented an amended version of the proposal. The Committee recognized that the 

regional associations were not aware of the Sector’s position on the proposed deletion of the reference to the 

calibration version and that the submitter has not had an opportunity to review the significant changes from the 

original version. T he 2012 S&T Committee designated this item as an Informational Item to allow additional 

opportunity for input. 

At the Sector’s August 2012 meeting, one member suggested that the phrase “or as otherwise specified by the 

customer” be modified to read “or as agreed to by the customer.” Customers are not going to proactively specify 
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C17

how elevator record keeping systems are put together, but they can agree that this information comes on a settlement 

sheet. A contract for the sale of grain at some future date with XYZ Grain contains a phrase that the seller agrees to 

XYZ Grain’s various transaction policies. B y signing the contract, the seller agrees to accept settlement sheet 

information via a web listing that can be accessed with a computer or possibly using a smart phone. The seller is not 

“specifying” how he wants to receive the “ticket” information, he is just “agreeing” to receive it in a d ifferent 

manner. 

The wording proposed by the Sector in 2011, “A printed ticket shall be made available to the customer upon request 

at the time of transaction...” did not require the customer to do anything if he didn’t want a ticket, but it did require 

him to ask for one if he wanted one. The wording in the Item under Consideration required the customer to say, “I 

don’t want a ticket ....” if a ticket wasn’t wanted. If he said nothing, he would be given a ticket (or offered one). 

Other Sector members felt that the wording of the Item under Consideration allowed flexibility, and most were in 

favor of accepting the Item under Consideration. An attempt to obtain a consensus on the S&T Committee’s 

proposal was unsuccessful due to one jurisdiction’s belief that ... “a ticket is given to the customer no matter what.” 

There was further discussion on whether the wording in the Item under Consideration, “..... at the time of the 

transaction or as otherwise specified by the customer” means that the customer gets a ticket at the time of transaction 

or at a later specified time. Some believed that “as otherwise specified by the customer” could mean “never” or “in 

another form.” Sector Chairman, Ms. Cassie Eigenmann, DICKEY-john, Corp., reminded the Sector that the reason 

Illinois Grain & Feed Association submitted the request for change was because they did not want to have to print a 

ticket at the time of transaction unless the customer requested one at the time of transaction. 

It was pointed out that unless a ticket is printed by the GMM before the grain sample is “dumped” from the GMM it 

may not be possible for the GMM to print a ticket for that transaction. The information, however, could reside in 

the memory of the elevator’s grain transaction system and could be printed in another form for example, on a 

settlement sheet that is sent (or transmitted) to the seller later. Further discussion suggested that the S&T proposed 

wording could be interpreted to mean that elevators that captured GMM information in their grain transaction 

system at the time of transaction would not have to supply a GMM printed ticket at time of transaction unless 

requested by the customer at time of transaction. If the elevator is using a GMM that is equipped to record and that 

was put into service before January 1, 1998, the elevator would be required to give the customer a printed ticket at 

the time of transaction (need print only percent moisture content and grain selected). 

Conclusion:

After further discussion a formal vote was taken to accept the Item Under Consideration as shown above. The vote 

was nine in favor to one opposed. The opposing vote was based on the implied need to give every customer a 

printed ticket. 

11. Update on Proficiency Testing

Source:

Dr. Hurburgh, Iowa State University

Purpose:

Develop an air-oven proficiency testing program to ensure state laboratory and manufacturers air-oven 

measurements are traceable to the official USDA, GIPSA air-oven measurements.

Item Under Consideration:

Create an ongoing air-oven proficiency testing program for states maintaining a grain moisture laboratory and GMM 

manufacturers.

Background/Discussion:

At the 2009 NTETC Grain Analyzer Sector Meeting, Dr. Hurburgh, Iowa State University, urged the representatives 

from the American Oil Chemists Society (AOCS) to prepare a proposal so that the collaborative (air-oven) study 
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C18

could be conducted on an on-going basis rather than on an ad hoc basis. He cautioned that the proposal would have 

to include corn and wheat as well as soybeans. 

At the 2011 NTETC Grain Analyzer Sector Meeting, Ms. Johnson, AOCS, proposed an air-oven/GMM proficiency 

testing series designed specifically to address the needs of GMM manufacturers and states maintaining a g rain 

moisture laboratory. A OCS would administer the program, oversee distribution of samples, compile results, 

perform statistical analysis of results, and distribute a report to participants. AOCS does not collect the samples. 

This is subcontracted to suitable providers. AOCS does not have laboratories. Since GIPSA/FGIS is a certified 

laboratory already participating in the AOCS Soybean Quality Traits program, GIPSA air-oven results could be 

reported for comparison.

At the Sector’s August 2012 meeting, the Sector learned that Ms. Christine Atkinson will be taking over the 

Proficiency Testing program for states and interested manufacturers formerly headed by Ms. Amy Johnson. 

Ms. Atkinson verified that participant’s cost will remain $100 per year. T he Sector reiterated that the program 

should focus solely on the standard FGIS air-oven method. Instrument results will not be reported. Participants’ 

air-oven results will be compared against GIPSA’s standard FGIS air-oven results. In response to Ms. Atkinson’s 

question about scheduling, the Sector was in general agreement that samples should ship after harvest, preferably 

between mid-January and mid-February with participants’ results due 30 days after the shipping date.

Conclusion:

In summary, the Sector agreed upon the following Program Details: 

• Samples – Soybeans 2, Corn 2, Hard Red Winter Wheat 2

• Cost to Participants – $100.00/year

• Schedule:

• Samples (6) ship between January 15 and February 15.

• Samples must be tested within 5 business days of receipt with results due 30 days after the shipping 

date.

• Reports to be posted on www.SoybeanQualityTraits.org by 1 May.

• Only the GIPSA oven results will be identified. Individual manufacturer’s and State participant’s oven 

results will be assigned an identifier known only to the manufacturer or State participant. Instrument results 

will not be reported. 

• Detailed Participant Instructions will be provided to each participant.

12. NCWM Publication 14, NTEP Administrative Policy Changes

Source:

NTEP

Background/Discussion:

NCWM is working on revisions to NCWM Publication 14, Administrative Policy, to put it in a more logical order 

and more understandable form. The purpose is not to change the intent of the publication, but to realign and clarify 

sections as necessary. Sectors, Committees, and the NTEP laboratories are asked to review the revised section, 

NTEP Administrative Policy and provide feedback. An electronic copy of the document was distributed by NCWM 

to all who registered to attend the NTETC Grain Analyzer Sector meeting in August.

Conclusion:

No comments were offered at the August 2012 Sector meeting. 

[Editor’s Note: On September 14, 2012, Mr. Don Onwiler, NTEP Executive Director, sent an e-mail message to 

GA Sector meeting attendees alerting them that the Administrative Policy document distributed for the Sector’s 

meeting was not the most up-to-date version. T he most recent copy is now posted to the GA Sector “meeting 

documents” page on the NCWM web site. It can be accessed at: http://www.ncwm.net/content/grain-analyzer-docs. 

Mr. Onwiler welcomes comments for the next two months.]

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C19

13. Next Sector Meeting

Mr. Jim Truex, NTEP Administrator, suggested that the Sector consider using some form of web conferencing if a 

meeting of only four or five hours would be required. At that time, it was difficult to determine what the outcome 

would be for the issues the Sector was forwarding to the S&T Committee. Should it be necessary to hold a physical 

meeting, the Sector agreed to the following tentative location and dates:

Dates: Wednesday, August 21 and Thursday, August 22, 2012 

Location: Chase Suites by Woodfin at KCI in Kansas City, Missouri (if available)

14. Review of Form 15s

Background/Discussion:

At the end of the first day of the Sector’s August 2012 meeting, the Co-Technical Advisors agreed to complete the 

Form 15s that would be required to move Agenda Items 4, 5, and 10 f orward. The following morning three

completed Form 15s were presented for the Sector’s review and approval:

1. Amend Table S.2.5. of §5.56.(a) in NIST Handbook 44 (see GA Agenda Item 4.)

2. Modify Definition of Remote Configuration (see GA Agenda Item 5.) 

3. S&T Committee Item 356-1 Printed Ticket User Requirements (See GA Agenda Item 10.)

Conclusion:

The Sector accepted Form15s “one” and “two” by consensus and “three” by a vote of 9 in favor to 1 opposed. As 

before, the opposing vote was based on the implied need to give every customer a printed ticket. 

15. Update on the New Meter Technology 

Background/Discussion:

The Sector invited Dr. David Funk, Deputy Director and Chief Scientist, GIPSA/FGIS Technology and Science 

Division, to update the Sector on the new meter technology. Following is a summary of his presentation: 

History of Official Moisture Meter Approvals

• 1937 – Tag-Heppenstall

• 1960 – Motomco Model 919 

• 1998 – DICKEY-john GAC 2100

• April 11, 2012 – First UGMA-Compatible moisture meters approved

– DICKEY-john GAC 2500UGMA

– Perten AM-5200-A 

What is GIPSA’s Unified Grain Moisture Algorithm (UGMA)?

• Very accurate dielectric-type moisture method

• Higher measurement frequency (about 150 MHz)

• Based on a defined physical parameter–Dielectric Constant

• Excellent density correction (Landau-Lifshitz, Looyenga Density Correction with LLL Exponent = 3)

• Three “unifying parameters” per grain group (Slope, Offset, and Translation Unifying Parameters)

• A single calibration “curve” for all grain types (a 5th-Order Polynomial)

• Precise, wide-range temperature correction

• Calibrated to GIPSA’s standard AIR Oven method

• “Open” – Available to any manufacturer 

Why Change to UGMA?

• Improved accuracy for all grain types
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C20

• Improved accuracy of UGMA 

• Improved year-to year calibration stability

• Drastically improved accuracy on high and low test weight corn

• Wider sample temperature ranges (allows measuring frozen grain)

• “Green” grain effects reduced (moisture “rebound” significantly reduced)

• Easier calibration development

GIPSA’s Basic Definition of Equivalency

• Same Technology

• Very close agreement among types as well as units of a type

• Same calibrations and standardization processes

UGMA – Compatibility Criteria

• NTEP Certification

• Documented and stable production processes

• Measurement frequency – 148.5 MHz to 150.5 MHz 

• Standardize Test cell design

• Standardized loading method

• Standardize measurements

– Sample dielectric constant

– Sample mass

– Sample temperature

• Tight tolerances specified for individual subsystems as well as for moisture results

• Must use specified mathematics

• Units’ agreement with FGIS Master system must meet tolerances in FGIS Regulations

– ± 0.05 % M for Headquarters Standard units

– ± 0.15 % M for other Official units

(where “M” is the mean difference on medium-moisture HRWW)

• All UGMA-Compatible models must be able to use the same check testing process.

• A simple check testing process must ensure performance on all grains over full moisture ranges.

• Instruments must provide for efficient means of entering calibrations.

• Instruments must provide standardized output data stream for printing or networking.

Anticipated Moisture Changes with Transition to UGMA

• GAC2100 and new UGMA-based meters are all calibrated to agree with GIPSA’s air oven method as 

closely as possible.

• Do not expect significant average differences between GAC2100 and new UGMA-based meters – 

except: 

• Low test weight corn moisture values will generally increase:

– GAC2100 reads lower than UGMA by 0.2 % per pound per bushel below 57 lb/bu.

• High test weight corn moisture values will generally decrease:

– GAC2100 reads higher than UGMA by 0.2 % per pound per bushel above 57 lb/bu.

Implications on Field-testing UGMA Meters 

• Better to test with another UGMA meter

• Alternatively, test with one sample of grain

• Test weight will make a difference in the moisture result of UGMA meters (May need to verify that 

UGMA meter is measuring mass correctly.)
NTEP Committee 2013 Final Report

Appendix C – NTETC 2012 Grain Analyzer Sector Meeting Summary

NTEP - C21

Implications for the Next Five Years

• There may be profound changes. Do we need NTEP phase 2?

• Reduction in the number of grain samples that are being collected but will not need to collect as many 

samples for the official meters which are UGMA meters now.

INTRODUCTION

The charge of the NTETC Measuring Sector (herein after referred to as “Sector”) is to provide appropriate type 

evaluation criteria based on specifications, tolerances and technical requirements of NIST Handbook 44,

Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices, Sections 

1.10. General Code and all portions of Section 3 including codes for Liquid Measuring Devices, Vehicle Tanks 

Meters, Liquid Petroleum Gas and Anhydrous Ammonia Measuring Devices, Cryogenic Liquid Measuring Devices, 

Milk Meters, Water Meters, Mass Flow Meters, and Carbon Dioxide Liquid Measuring Devices. T he Sector’s 

recommendations are presented to the National Type Evaluation Program (NTEP) Committee each January for 

approval and inclusion in NCWM Publication 14, Technical Policy, Checklists, and Test Procedures for national 

type evaluation.

The Sector is also called upon occasionally for technical expertise in addressing difficult NIST Handbook 44 issues 

on the agenda of National Conference on Weights and Measures (NCWM) Specifications and Tolerances (S&T) 

Committee. S ector membership includes industry, NTEP laboratory representatives, technical advisors, and the 

NTEP Administrator. Meetings are held annually, or as needed and are open to all NCWM members and other 

registered parties.

Suggested revisions are shown in bold face print by striking out information to be deleted and underlining

information to be added. Requirements that are proposed to be nonretroactive are printed in bold-faced italics. 

Note: It is policy to use metric units of measurement in publications; however, recommendations received by 

NCWM technical committees and regional weights and measures associations have been printed in this publication 

as submitted. Therefore, the report may contain references to inch-pound units.

CARRY-OVER ITEMS:

1. Add Testing Criteria to NTEP Policy U “Evaluating Electronic Indicators Submitted Separate 

from a Measuring Element” 

Source: 

California NTEP Lab

Background: 

At its 2007 meeting, the Measuring Sector heard that Technical Policy U in Pub 14 allows for testing an indicator 

separate from a measuring element. However, specific test criteria had not been developed for this practice. The 

Sector heard a r ecommendation to develop and add specific criteria for testing an indicator separate from a 

measuring element. 

From 2007 to 2010, the California NTEP Laboratory worked to develop a checklist, but had received limited input 

on the drafts. At the 2009 Sector meeting, Mr. Dan Reiswig (CA DMS) provided an update to the Sector on the 

progress of the project. He presented a d raft checklist, noting that the checklist follows the general format of 

NCWM Publication 14 and the main test procedures are at the end of the document. At the 2010 Sector meeting, 

Mr. Reiswig presented a list of the areas of the checklist that specifically needed further attention and review. 

Appendices A and B, submitted by Mr. Reiswig, contain the draft checklist and proposed revisions to Technical 

Policy T.
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D4 

At the conclusion of its 2011 meeting: 

The Sector agreed that additional work is needed to finalize the checklist. Mr. Rich Miller (FMC) volunteered to 

serve as Chair of the Work Group. Sector Technical Advisor, Mr. Marc Buttler (NIST OWM), will assist as needed 

and monitor progress of work.

Discussion: 

Mr. Miller reported that a new electronic indicating device is very close to being released by FMC. FMC would like 

to use the normal NTEP evaluation of this device as an opportunity to help complete the new checklist. Results 

from a “bench test trial” using the draft checklist will be used by the Work Group and brought back to the Sector. 

Mr. Miller understands that, once the checklist has been adopted in NCWM Publication 14, an indicator will not 

require a permanence test beyond the initial laboratory bench testing for approval in stationary applications because

there is no wear on an electronic indicator that results from product flow as there is with a measuring element. 

However, since the checklist has not yet been completed by the Sector, Mr. Miller is planning for the device to

undergo both the bench test trial of the new checklist and a full field evaluation, including a full permanence test on 

a vehicle.

Mr. Miller expects the new FMC device will be submitted for NTEP evaluation for a vehicle-mounted approval by 

the end of 2012. This device receives a pulse input representing the measured quantity. Serial communication from 

the measuring device is not within the scope of the proposed evaluation.

It was proposed by FMC that the bench testing could be conducted at the ISO 17025 accredited FMC Lab in Erie, 

Pennsylvania, in December. The truck on which the device will be mounted for field-testing and permanence 

evaluation is also located in Erie. 

Final details regarding assignment of the project to one of the NTEP labs and timing will need to be decided at the 

time the device is submitted. However, because all the work on the checklist to date has originated from California, 

the Sector, with the concurrence of the NTEP Director, agreed that the CA DMS NTEP Lab would be the preferred 

lab for the trial as long as there are no scheduling issues.

Decision: 

The Sector agreed to carry the item over to the Sector’s next meeting based on the recommendation from the 

Work Group to allow for completion and trial of the checklist. M r. Jack Kiefert (Honeywell Enraf) has 

volunteered to join the group. 

Work Group members as revised at the Sector’s 2012 meeting are listed below:

Appendices A and B to this summary contain the draft checklist and proposed revisions to Technical 

Policy T. submitted by Mr. Reiswig. The Work Group was asked to address the highlighted sections in the 

draft checklist. The Work Group was also asked to address the five points below and then submit the 

finished checklist to the two lab representatives listed above for review and comment.
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D5 

1) A minimum of 10 000 pulses must be collected. To ensure that there will be a change in the displayed 

indication for each pulse received, the electronic indication should be scaled such that the value of the 

smallest indicated division should equate to less than or equal to the value associated with one input 

pulse.

2) It is important to validate whether ± 1 pulse is an appropriate tolerance, taking into consideration 

applicable OIML requirements.

3) The number of different temperature inputs and API gravity values that would need to be tested to 

adequately verify the temperature compensation function of an electronic indicator must be 

determined. It has been proposed that spot-checking of three random tables at three different 

temperatures would be adequate to verify that an indicator’s temperature compensation feature is 

functioning properly.

4) A step for checking multipoint calibration along with associated guidance should be developed and 

added to the checklist. This guidance should emphasize the necessity of working with the 

manufacturer of each device in order to set up tests to properly check multipoint calibration using 

simulated pulses.

5) Addressing various different input signal formats including pulses, analog, and digital 

communication will be challenging. A nalog (4-20 mA) input devices are to be excluded from the 

scope at this time. The Work Group is asked to address pulse (frequency) signals in the final version 

of the checklist and is asked to consider whether or not to also include digital communications.

2. Product Families Table - Include Water on Existing NTEP CC’s

Source: 

Dmitri Karimov, Liquid Controls

Background: 

Flow meters are approved to very tight tolerances on aggressive liquids such as acids, alcohols, glycol/water 

mixtures, and liquid fertilizers. Many of these liquids, including glycol/water mixtures and some liquid fertilizers, 

are water-based. Water is a less aggressive fluid and has a wider NIST Handbook 44 tolerance than these liquids.

A note at the end of the Product Families Table in NCWM Publication 14 allows water to be used as a test product 

in the “Fuels, Lubricants, and Industrial and Food-grade Liquid Oils” product family.

Despite these points, NCWM Publication 14 requires separate tests with water in order to add water to an existing 

PD or turbine meter NTEP CC which was issued based on tests with other products in the “Fuels, Lubricants, and 

Industrial and Food-grade Liquid Oils” product family. 

At the conclusion of its 2011 meeting: The Sector voted on a proposal to add a note to the end of the Product 

Families Table that would apply to all technologies as follows:

The water family (in its entirety or partially – as determined by NTEP) can be included on an NTEP CC 

based on an approved product or range of products with similar metrological characteristics (specific 

gravity, conductivity, and viscosity – as applicable to the relevant meter technology) unless materials 

constituting the measuring element are known to deteriorate in contact with water.

The proposal and the results of the vote shown below were forwarded to the NTEP Committee.

In favor: 9 

Opposed: 3 

Abstained: 1 

Note: Two of the three labs were opposed to the item.

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D6 

On January 21, 2012, the NTEP Committee returned this item to the Sector for further consideration, noting that 

because the majority of the NTEP labs did not concur with the proposal, the conclusion did not represent a 

consensus among all segments of the membership. 

Discussion: 

At its 2012 meeting, the Sector reviewed and discussed each of the five points that were noted as unresolved issues 

in the 2011 summary: 

Issue 1: The proposal to leave the decision of whether to add water to a CC without any additional testing 

up to the judgment of the NTEP labs on a case-by-case basis caused concern among some Sector 

members. The labs and some manufacturers were concerned that such ambiguity in NTEP policy 

could lead to unintentional inconsistency and less predictable outcomes during type evaluations.

The Sector discussed how, in order to replace testing with their judgment alone as the means of verifying 

suitability and metrological integrity of a meter with a new product family, the NTEP labs would need to 

invest in developing material compatibility expertise that would extend beyond what is justified by their 

primary mission.

Issue 2: A concern was raised about the application of the LMD Code and the Water Meters Code in NIST

Handbook 44. Paragraph A.2.(d) of the LMD Code specifically excludes water meters. T his 

exclusion requires a meter that already has a CC under the LMD Code to meet a potentially 

different set of requirements found in the Water Meters Code in order to add water to the CC. For 

example, a 3” size PD meter that is already approved under the LMD Code with a maximum 

discharge rate of 300 gpm would be required by paragraph S.4.4.1. in the LMD Code (Section 3.30.)

to have a minimum discharge rate not to exceed 20 % of the marked maximum discharge rate, or 

60 gpm. Therefore, the meter could be approved for use in applications other than water with a 

flow rate range from 60 gpm to 300 gpm. However, to comply with paragraph N.4.2. “Special 

Tests” in the Water Meters Code (Section 3.36.), the device would need to be able to pass special 

tests at 20 gpm, as shown in Table N.4.2.a.; this flow rate is three times smaller than what would 

normally be permitted by the LMD Code to be the smallest minimum rated discharge rate.

The Sector discussed emerging commercial water-measuring applications, such as Water-For-Injection 

(WFI), where the value of the water has been increased by industrial processes and larger quantities are 

measured. In these applications, a device other than a traditional utility water meter is generally 

preferred. With the emergence of new water-measuring applications, manufacturers question whether the 

requirements for traditional utility and batching applications, especially those that restrict flow rate ranges 

by meter size, should still apply to all applications that measure water of every type. It is possible that 

paragraph G-A.3. “Special and Unclassified Equipment” in NIST Handbook 44 may apply to some 

emerging applications that do not clearly fit the standard utility and batching applications that the Water 

Meters Code is intended to address. The Sector noted that there are already exceptions in the Water 

Meters Code that exclude mass flow meters and meters mounted on vehicle tanks. In both of these cases, 

meters must meet more stringent requirements, but are afforded greater flexibility of flow rate ranges than 

those that are allowed in the Water Meters Code.

More information is needed about the specific parameters of emerging water-measuring applications that 

do not fit clearly into the range of applications that are intended to be addressed by the Water Meters 

Code in order to develop a proposal to update NIST Handbook 44 for these applications. It is not yet 

clear from what is currently known whether it would be more appropriate to expand the scope of the 

Water Meters Code to address new applications or to modify the exception to water meters in the LMD 

Code to allow for certain types of water-measuring applications. In either case, the nature of the new 

applications must be well understood in order to justify a proposal to change NIST Handbook 44.

Issue 3: The Sector understands that any amount of testing will require some resources, and an effort is 

made to avoid policies that are not essential to assuring metrological integrity that might impose 

unreasonable burdens on manufacturers. However, several manufacturers stated that they often 

test on water and did not understand how testing with water could be viewed as an unreasonable 

burden. 

The Sector discussed whether it would create a burden for some devices to require testing with water if 

the device is difficult to test on water because of questionable material compatibility. T he Sector 

concluded that testing with water is even more important for devices which are marginally compatible 

with water or for which the compatibility with water is not well understood because the device was not 

originally intended to measure water.

Issue 4: There were concerns raised that water has been grouped separately in the product families table in 

the past for a reason, and that different types of water can affect measuring devices differently. 

It was proposed to revise the Product Families Table, but a detailed proposal has not yet been developed.

Issue 5: A concern was raised that the word “similar” as used in the proposed language needed to be 

defined in more detail. During the 2011 Sector meeting, a definition for “similar” was proposed by 

one manufacturer as describing a group of two or more fluids that share the same value of the 

single critical property that applies to the device technology of concern (i.e., dynamic viscosity for 

PD meters, kinematic viscosity for turbine meters, specific gravity for mass flow meters, and 

conductivity for magnetic flow meters). T his definition of similar fluids did not offer any 

explanation as to the reason that there are multiple product families in the Product Families Table 

which are similar as far as the critical property, but nevertheless have been defined as separate 

families ever since the adoption of the original version of the table. 

The Sector agreed that some of the different product families were created to match meters made with 

different materials of construction. However, no one could say with certainty whether or not there are 

additional fluid product properties beyond the critical property for the device in question that affect the 

metrological integrity and durability of different measuring device types.

The submitter proposed withdrawing the item in recognition that there is no consensus support for the item as it is 

currently presented. Mr. Dmitri Karimov (Liquid Controls) plans to develop and submit a new item that will replace

the current Agenda Items 2, 3, and 4.

Decision: The Sector agreed to Withdraw the item and anticipates Mr. Karimov will introduce a new item 

that combines Items 2, 3, and 4 f rom the 2012 S ector Agenda and which includes a detailed draft in the 

format of the Product Families Table.

3. Product Families Table – Change Test Requirements for Turbine Meters from Test A to 

Test E

Source: 

Dmitri Karimov, Liquid Controls

Background: 

In the Product Families Table of NCWM Publication 14, turbine meters require testing on individual products with 

some exceptions. This approach, which was appropriate many years ago when turbine meters were first entering the 

custody transfer arena, has become outdated. Turbine meters have been tested extensively by NTEP. The submitter 

contends that turbine meters need to at least have product tests match those of PD meters because turbine meter 

influence factors are similar to those of PD meters.

Discussion: 

Mr. Karimov suggested Withdrawing the item until such time as a more detailed proposal that includes a draft of the 

changes to the Product Families Table can be completed. The Sector agreed that much of the discussion pertaining 

to Agenda Item 2 also applied to this item.

Decision: 

The Sector agreed to Withdraw the item and anticipates Mr. Karimov will introduce a new item that 

combines Items 2, 3, and 4 from the 2012 Sector Agenda and which includes a detailed draft in the format of 

the Product Families Table.

4. Product Families Table – Consolidate Product Categories for PD and Turbine Meters 

Source: 

Dmitri Karimov, Liquid Controls

Background: 

The submitter believes that NCWM Publication 14 (Pub 14) has too many agri-chemical products categories for PD 

and turbine meters that were created many years ago and are outdated. Note that this item relates to the proposal in 

Agenda Item 3 to match PD and turbine product categories.

At the conclusion of its 2011 meeting: The Sector voted on a proposal to add a note, as shown below, to the LMD 

Technical Policy. 

If a PD or turbine meter is approved for a product of low viscosity in one product family or category and 

the same model meter is approved for a product of high viscosity in another product family or category, the 

meter will be approved for this viscosity range in both product families/categories.

The proposal and the results of the vote shown below were forwarded to the NTEP Committee.

Approve: 7 

Oppose: 5 

Abstain: 0 

Note: All three labs and NIST were opposed to the item as it was framed for the vote.

On January 21, 2012, the NTEP Committee returned the item to the Sector for further consideration noting that 

because the NTEP labs and NIST did not concur with the proposal, the conclusion did not represent a consensus 

among all segments of the membership. 

Discussion: 

The Sector discussed the responses of the NTEP Committee to the voting results of Agenda Items 2 and 4. Even 

though an overall majority of the Sector members had voted in favor of both items, the NTEP Committee could not 

regard the proposals as representing consensus recommendations since a majority of one of the membership 

segments voted against each item. Because the NTEP Committee regards the input and participation from each 

segment of the Sector membership as critical, the committee regards such cases as a strong indication that an item 

needs further development.

Mr. Henry Oppermann (Weights and Measures Consulting) suggested that aligning proposals with OIML standards 

is often helpful in avoiding gaps in understanding between public and private sector members of the Sector. 

Mr. Dennis Beattie (Measurement Canada) mentioned that Canada is also attempting to address the organization of 

product fluid properties and meter materials of construction for the purpose of determining appropriate testing 

requirements for type evaluation.

The submitter proposed withdrawing the item in recognition that there is no consensus support for the item as it is 

currently presented. Mr. Karimov plans to develop and submit a new item that will replace the current Agenda

Items 2, 3, and 4.

NTEP - D9 

Mr. Buttler mentioned that he is available to provide technical guidance to Mr. Karimov in developing the draft 

proposal. H owever, industry must develop the item to ensure that the interests of industry are reflected by the 

proposal. Mr. Karimov commented that he would focus primarily on the test requirements for turbine meters in the 

new proposal. 

The NTEP labs noted that a reference tool similar to the Product Families table is needed to capture the critical 

properties for each individual fluid. B ecause the Product Families Table is not all-inclusive and only provides 

information on the typical range of critical property values for each product family, the values for individual 

products must be determined by some other means. The Sector noted that the Product Families Table does not 

currently include all fluid products sold commercially and agreed that such a tool would be useful to aid field 

inspectors in enforcement and NTEP labs during type evaluation. However, the Sector also noted that it would be 

cumbersome to maintain the increasing volume of data that would be needed to achieve this. 

Decision: 

The Sector agreed to Withdraw the item and anticipates Mr. Karimov will introduce a new item that 

combines Items 2, 3, and 4 from the 2012 Sector Agenda and which includes a detailed draft in the format of 

the Product Families Table. 

The Sector requested that the Technical Advisor, Mr. Buttler, provide assistance by researching historical 

records for any information listing the various fluid product properties that were considered when the 

product families for PD and turbine meters were first drafted by Mr. Mel Hankel of Liquid Controls for the 

original Product Families Table proposal.

Technical Advisor’s Note: Mr. Buttler located information from the NIST file on the 1991 Measuring Sector 

meeting and attached the information to this summary as Appendices C and D.

Appendix C is a scanned image of a detailed letter from Mel Hankel to NIST that describes the interrelations 

between meter materials of construction and fluid product properties that formed the basis of the original 

proposal to streamline NTEP type testing by grouping fluids together into families. Appendix D is a technical 

paper from Smith Meter Inc. that includes additional technical information about interactions between meters 

and fluids with varying properties.

Appendices C and D identify the following fluid properties as properties that were considered during the creation 

of the original Product Families Table:

• Viscosity

• Specific Gravity

• Percent of Abrasive Solids

• Lubricity Service Factor

• Typical Flow Rate Range Ratio

• Corrosiveness

• Vapor Pressure

• Homogeneity

• Solids (Particulate) Content

• Typical Temperature Ranges

• Typical Pressure Ranges

• Boundary Layer Thickening

• Deposits (e.g., paraffin)

The 1991 discussion also noted that, at the time, Liquid Controls was producing 15 PD meter classes using 

various different materials of construction to address the anticipated range of these various fluid properties. 

One additional fluid property was the subject of discussion in the 1991 Sector meeting. Entrained vapor/air

resulting from agitation of fluids (e.g., fertilizers) was discussed at length with respect to the impact on 

effectiveness of the vapor/air elimination means of some measuring systems. Multiple fluid properties (e.g., 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D10

viscosity and surface tension) will determine how entrained vapor/air will be dispersed in an agitated fluid and 

how quickly and effectively the entrained vapor/air can be eliminated.

The information from the 1991 Measuring Sector archive, Appendices C and D, in combination with more recent 

data from industry regarding the effects of various fluid properties on the latest metering technologies should be 

helpful to Mr. Karimov in developing the new proposal referenced above. If it can be shown which of the 

properties from the list above are the key characteristics for each of the currently defined product families, this 

understanding could then help to justify the specific details of a reorganization and consolidation of the Product 

Families Table.

NEW ITEMS:

5. Pictograms for “Setup or Configuration Mode Enabled” 

Source: 

NTEP Measuring Labs

Background: 

At the spring 2012 meeting of the NTEP measuring labs, the labs agreed that pictogram is clear and acceptable 

indication of the status of the setup or configuration mode while sealing a d evice. To clarify acceptability of 

pictograms such as these, it is proposed that an example be added under the heading of Acceptable Clear Indications 

to the list of indications representing that the device is configured with the setup or configuration mode enabled. 

Recommendation: 

The Sector was asked to consider adding a pictogram to the sealing checklist table under examples of Acceptable 

Clear Indications that a device has the setup or configuration mode enabled as shown in the lower left corner of the 

figure below. 

Indications representing that the device is configured with the setup or configuration 

mode enabled (i.e., any mode permitting access to any or all sealable parameters)

This list is not limiting or all-inclusive; other indications may be acceptable.

It was also recommended that the Sector consider adding an accompanying checklist table to show examples of 

optional indications that a device is in the sealed mode or has setup or configuration mode disabled. Indication of 

this mode is currently neither required nor prohibited in NIST Handbook 44.

Indications (optional) representing that the device is configured with the setup or 

configuration mode disabled (i.e., no access to any or all sealable parameters) 

This list is not limiting or all-inclusive; other indications may be acceptable.

Acceptable Clear Indications

Discussion: 

The Technical Advisor summarized the two parts of the proposal:

• the addition of a pictogram example to the exiting table of indications representing that the device is 

configured with the setup or configuration mode enabled, and

• the addition of a second table to show examples of indications representing that the device is configured 

with the setup or configuration mode disabled.

The Sector first discussed the existing table of indications representing that the device is configured with the setup 

or configuration mode enabled. The Sector noted that NCWM Publication 14 does not now prohibit the use of 

pictograms. The Sector agreed that adding examples of acceptable pictograms could avoid confusion as to whether 

pictograms are acceptable and would provide manufacturers that are submitting new devices with the pictogram 

options that have been reviewed previously and determined to be clear indications. 

The Sector noted that the location of the title of the table as it appears in the proposal was inside the top cell of the 

table, and that this was in contrast to the location of the title of the table as separate text above the table where it 

currently appears in NCWM Publication 14. It was proposed that the table title and the note indicating that the list is 

not all-inclusive should remain as separate text above the table. The Sector agreed to keep the title and the note

above the table to remain consistent with the way that other similar tables appear in NCWM Publication 14. 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D12

The Sector discussed the requirement found in Table S.2.2. “Categories of Device and Methods of Sealing” from the 

LMD Code in NIST Handbook 44 that applies to Category 2 and Category 3 devices:

The device shall clearly indicate that it is in the remote configuration mode and record such message if 

capable of printing in this mode or shall not operate while in this mode.

The Sector noted that there is no corresponding specific requirement in NIST Handbook 44 for a device to indicate 

when the remote configuration mode is not enabled. The Sector’s interpretation of this is that, although it 

is permitted for a device to indicate when the remote configuration mode is not enabled, it is only required for the 

device to indicate when the remote configuration mode is enabled. A concern was raised about adding examples of 

indications that are permitted but are not required. The Sector ultimately decided not to add the additional table that 

was proposed which would have listed the optional indications representing that the device is configured with the 

setup or configuration mode disabled. 

Decision: The Sector unanimously agreed to propose adding the pictogram example and the additional 

wording to the note under the title of the existing table as shown underlined below. The Sector also decided 

not to include the new additional table that had been proposed to show optional indications representing that 

the device is configured with the setup or configuration mode “disabled.” 

The title, note, and table should appear with the revisions as shown here:

Indications Representing That the Device is Configured with the Setup or Configuration Mode Enabled 

(i.e., any mode permitting access to any or all sealable parameters)

This list is not limiting or all-inclusive; other indications or pictograms may be acceptable.

6. Utility Water Meter Repeatability Tolerances

Source: 

NTEP Measuring Labs

Background: 

The new Section L “Laboratory Evaluation and Permanence Tests for Utility Type Water Meters” that was added to 

NCWM Publication 14 in 2012 includes repeatability tolerance values for utility-type meters. At the spring 2012 

meeting of the NTEP measuring labs, the labs recommended that these tolerance values be removed from NCWM 

Publication 14. Tolerance values are published in NCWM Handbook 44, and it is standard practice to refer to NIST 

Handbook 44 as the sole location of all tolerance values.

Recommendation: 

The Sector was asked to consider removing the tolerance values for utility-type water meters from NCWM

Publication 14 as shown below. 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D13

L. Laboratory Evaluation and Permanence Tests for Utility Type Water Meters 

All new-design meters are subject to a permanence test. NTEP reserves the right to require a permanence test 

based on the results of the initial examination.

Initial Examination

1. All meters of the new type installed at the type evaluation location are subject to evaluation. At least 

three meters of the same model must be tested.

2. At least three meters will be chosen for throughput testing on water. The minimum number of tests to be 

conducted for each of these meters will include the following:

• Three tests at the maximum flow rate

• Three tests at the intermediate flow rate

• Three tests at the minimum flow rate

3. All meters must perform within acceptance tolerance.

4. Repeatability – When multiple tests are conducted at approximately the same flow rate, each test shall be 

within the applicable tolerances and the range of test results shall not exceed repeatability 

tolerance. the following values:

1. 0.6 percent for tests conducted at Normal Flow Rates

2. 2.0 percent for tests conducted at Intermediate Flow Rates

3. 4.0 percent for tests conducted at Minimum Flow Rates

Subsequent Examination

1. Following the period of use, the tests listed above are to be repeated. All results within the range of flow 

rates are to be included on the certificate of conformance provided the results are within the applicable 

tolerances.

2. The examination will be conducted as applicable:

• 200 000 gallons for throughput testing for mechanical changes of metrological significance

• Flow rates during throughput testing are not to exceed 50 % of the manufacturers rated maximum 

flow rate

3. Three tests at maximum, intermediate and minimum flow rate will be made on the throughput meters. 

Only one test at each flow rate needs to be performed on any remaining meters.

4. Repeatability – When multiple tests are conducted at approximately the same flow rate, each test shall be 

within the applicable tolerances and the range of test results shall not exceed repeatability 

tolerance. the following values:

1. 0.6 percent for tests conducted at Normal Flow Rates

2. 2.0 percent for tests conducted at Intermediate Flow Rates

3. 4.0 percent for tests conducted at Minimum Flow Rates

Discussion: 

The Sector discussed the item and agreed that the convention in NCWM Publication 14 of not listing tolerance 

values, but rather referring directly to NIST Handbook 44 for tolerance values should apply for water meters as well.

Technical Advisor’s Note: Clarifications that repeatability tests are three or more consecutive tests were added as 

an editorial change to reflect paragraph N.4.1.1. “Repeatability Tests” in the HB 44 Water Meters Code.”

Decision:

The Sector unanimously agreed to propose removing the tolerance values for utility-type water meters from 

NCWM Publication 14 as shown below.

7. Water Meters Permanence Flow Rates

Source: 

NTEP Measuring Labs

Background: 

The new Section L “Laboratory Evaluation and Permanence Tests for Utility Type Water Meters” that was added to 

NCWM Publication 14 in 2012 includes a restriction preventing throughput flow rates to 50 % of maximum rated 

flow rate and below. The NTEP labs report that past laboratory throughput testing of water meters has been run 

with flow rates near the maximum rated flow rate. Water meters in service are often found that are nearly 

continuously subjected to flow at close to the maximum rated flow rate. The labs feel it is important to be able to 

conduct testing under the conditions in which the meters will be used.
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D15

Recommendation: 

The Sector was asked to consider removing the restriction in Section L that prevents throughput flow rates above 

50 % of maximum rated flow rate as shown below.

Subsequent Examination

1. Following the period of use, the tests listed above are to be repeated. All results within the range of flow 

rates are to be included on the certificate of conformance provided the results are within the applicable 

tolerances.

2. The examination will be conducted as applicable:

• 200 000 gallons for throughput testing for mechanical changes of metrological significance

• Flow rates during throughput testing are not to exceed 50 % of the manufacturers rated maximum 

flow rate

3. Three tests at maximum, intermediate, and minimum flow rate will be made on the throughput meters. 

Only one test at each flow rate needs to be performed on any remaining meters.

4. Repeatability – When multiple tests are conducted at approximately the same flow rate, each test shall be 

within the applicable tolerances and the range of test results shall not exceed repeatability tolerance.

Discussion: 

The Sector revisited the question of what limit, if any, is appropriate to place on the throughput flow rate during 

permanence testing of utility type water meters. Mr. John Roach (CA DMS NTEP Lab) said that the water meter 

testing in California regularly runs throughput flow rates on 5

/8-inch meters at 15 gpm. He also mentioned that 

utility type water meters of similar size would often run continuously at this same high flow rate while in service. 

Sector members agreed that, for a permanence test to be valid, the meter should be allowed to run throughput at a 

flow rate similar to that at which a meter of the type is expected to see in service.

Mr. Andre Noel (Neptune Technology Group, Inc.) explained that there appears to be confusion when referring to 

the “manufacturer’s rated maximum flow rate” resulting from a difference in nomenclature between NCWM 

Publication 14; the ANSI/AWWA C700 “AWWA Standards for Cold-Water Meters”; and the Water Meters Code 

(Section 3.36.) in NIST Handbook 44. In the AWWA standard, the “recommended maximum rate for continuous

operations” for cold-water meters is limited to 50 % of the “safe maximum operating capacity” flow rate. AWWA 

C700 describes the “safe maximum operating capacity” as the maximum rate of flow that water should be passed 

through the meter. AWWA adds that the maximum rate should extend only for short periods of time and at 

infrequent intervals, and that maximum flow could be destructive if continuous.

Mr. Noel further explained that the flow rates for normal tests listed in Table N.4.1. in the Water Meters Code in

NIST Handbook 44 are lower than the “safe maximum operating capacity” flow rate values in AWWA C700. The

limit on the throughput of “50 % of the manufacturer’s rated flow rate” currently stated in Section L of NCWM 

Publication 14 was intended to prevent continuous throughput flow at “safe maximum operating capacity” flow rates 

and thus avoid the potential destructive effects of continuous flow at those rates. 

Since neither the “manufacturer’s rated flow rate” from NCWM Publication 14 nor the “safe maximum operating 

capacity” from the AWWA standard are terms that are currently referenced or defined in NIST Handbook 44, the 

Sector agreed to reword the description of the throughput flow rate limit in Section L of NCWM Publication 14 

using terms referenced in NIST Handbook 44 and AWWA C700. Mr. Noel and other Sector members agreed that 

the throughput flow rates for water meters should be allowed to run at 100 % of the normal test flow rates in the 

NIST Handbook44 Water Meters Code Table N.4.1. or up to the manufacturer’s recommended maximum rate for 

continuous operations, if that is higher. Mr. Roach confirmed that these flow rates represent the testing practices 

that are currently in place in California and are also reflective of normal continuous use conditions for utility type 

water meters. 

Decision: 

The Sector unanimously agreed to propose revisions to the wording of the “Subsequent Examination” steps 

in Section L of NCWM Publication 14 as shown below to resolve the nomenclature differences between 

NCWM Publication 14 and AWWA C700.

Subsequent Examination

1. Following the period of use, the tests listed above are to be repeated. All results within the range of flow 

rates are to be included on the certificate of conformance provided the results are within the applicable 

tolerances.

2. The examination will be conducted as applicable:

• 200 000 gallons for throughput testing for mechanical changes of metrological significance

• Flow rates during throughput testing are not to exceed the normal flow rate from HB 44 or a 

stated maximum continuous flow rate from the manufacturer, if it is greater than the normal 

flow rate. 50% of the manufacturers rated maximum flow rate

3. Three tests at maximum, intermediate and minimum flow rate will be made on the throughput meters. 

Only one test at each flow rate needs to be performed on any remaining meters.

4. Repeatability – When multiple tests are conducted at approximately the same flow rate, each test shall be

Background: 

At their April 2000 meeting, the NTEP laboratories agreed that if a meter is successfully tested in a vehicle-mounted 

application, the resulting CC could cover both vehicle-mounted and stationary applications without additional 

testing in a stationary application. The labs forwarded a proposal to the Measuring Sector to add a new paragraph to 

the Technical Policy for Liquid-Measuring Devices, and this resulted in the addition of Technical Policy R 

“Vehicle-Mounted and Stationary Applications of the Meter” to Pub 14.

Since it was originally developed, Technical Policy R has referred only to “the meter.” NIST has received inquiries 

from industry requesting clarification on whether the scope of Technical Policy R is intended to include registers. 

Discussion notes from the 2000 Measuring Sector meeting confirm that the proposal was originally based on 

recognition that the vehicle-mounted application is the worst case of the two scenarios. There is no mention of any 

intention to exclude registers from the scope of this conclusion.

Recommendation: 

The Sector was asked to consider clarifying Technical Policy R to include registers within the scope as shown in the 

decision below. 

Discussion: 

The Sector discussed the item and all agreed that the scope of Technical Policy R was intended to include both 

meters and registers. Several suggestions were offered to clarify the language that was initially proposed. However, 

after some discussion, all agreed to leave the original language of the proposal intact..

Decision: 

The Sector unanimously agreed to propose the change as it appears below. 

R. Vehicle-Mounted and Stationary Applications of the Meters and Registers 

If a meter or register is successfully tested in a vehicle-mounted application, both vehicle-mounted and 

stationary applications can be covered on the resulting NTEP Certificate of Conformance (CC) without 

additional testing in a stationary application provided all other suitability criteria have been met (e.g., 

flow rates). If a meter or register evaluation has only been conducted in a stationary application, testing

must also be conducted on the meter or register in a vehicle-mounted application in order to cover both 

applications on the NTEP CC.

9. Product Families Table - Correct the Units for the Turbine Meter’s Critical Parameter of 

Kinematic Viscosity to Centistokes (cSt) in the Product Families Table 

Source: 

Marc Buttler, NIST OWM

Background: 

In 2010, the Measuring Sector recommended a new format to reorganize the Product Families Table of Technical 

Policy C. The NTEP Committee approved the new format of the table and it was published in the 2011 edition of 

NCWM Publication 14.

The Sector had been working to develop the new format since 2006, but limited the scope of these discussions to 

revising the format and not the content of the table. See the 2006 – 2010 Measuring Sector Meeting Summaries for 

details.

The way in which viscosity units were presented in the older format of the table led to an error in how the content 

was translated to the new format. Viscosity units for both PD and turbine meters had previously been combined in 

the old format in a single column labeled “Viscosity (Centipoise Centistokes).” The correct unit for the critical 

parameter of “kinematic viscosity” that applies to turbine meters is centistokes (cSt). The correct unit for the critical 

parameter of “dynamic viscosity” that applies to PD meters is centipoise (cP). Dynamic viscosity is commonly 

referred to as either just “viscosity” or sometimes “absolute viscosity.”

The relationship between centistokes and centipoise is shown in the following equations:

centistokes (10-6 m2

/s) = centipoise (10-3 kg/m·s) ÷ density (kg/m3) 

OR

centistokes (cSt) = 1.002 × centipoise (cP) ÷ density (SG) [Where 1 SG = 998 kg/m3

] 

In the Product Families Table, Test E, which has always been reserved exclusively for turbine meters, specifies 

kinematic viscosity as the correct critical parameter for turbine meters.

Test E

To cover a range of products within each product category, test with one product having a low kinematic 

viscosity and test with a second product having a high kinematic viscosity within each category. The 

Certificate of Conformance will cover all products in the product category within the kinematic viscosity

range tested.

Furthermore, the approved range of kinematic viscosity in active turbine meter CCs is identified using units of 

centistokes as the critical parameter. 

Recommendation: 

The Sector was asked to consider correcting the unit labeling of all references to kinematic viscosity under the 

turbine meter columns of the Product Families Table in Technical Policy C to centistokes (cSt) as shown in the 

example below. A complete markup with all changes to the table was provided (Appendix E). In addition to the 

corrections of the unit labels, the markup also included updated kinematic viscosity values for each product that 

were computed from the dynamic viscosity and density values found for each product elsewhere throughout the 

table. The conversions between units of centipoise and centistokes in Footnote 1 of the table were also clarified in 

the Attachment 3 markup.

Discussion: Mr. Buttler (NIST, OWM) reviewed how the error in units of viscosity occurred during the translation 

of the Product Families Table into the new format. Mr. Buttler also explained how the corrected values for 

kinematic viscosity for turbine meters in the proposed table shown in Appendix E were derived from other values 

already in the table. Values for dynamic viscosity in centipoise from the PD meter column of the table and SG 

values from the mass meter column were used in the formula stated above and in the footnote below the table to 

compute the kinematic viscosity values in the turbine meter column. Correcting the units to kinematic viscosity for 

turbine meters is essential to preserve the technical accuracy of the table, as well as the accuracy of active CCs that 

already state kinematic viscosity ranges for approved turbine meters in units of centistokes (e.g., CC 04-097A3).

Decision: 

The Sector unanimously agreed to propose the changes as shown in Appendix E. 

10. Post-Delivery Discounts and Electronic Receipts

Source: 

2012 NCWM S&T Committee Item 330-1 (Unit Price Posting and Selection Requirements) 

Background: 

At the 2012 NCWM Annual Meeting, S&T Item 330-1 was approved to update specifications in NIST Handbook 44 

to address current marketing methods for offering pricing discounts beyond simple cash/credit pricing and to 

establish a framework for “post-delivery” discounts offered after the delivery of fuel is complete. 

Recommendation: 

The Sector was asked to update the LMD and ECR-RMFD checklists to reflect the new requirements relating to 

post-delivery discounts and availability of electronic receipts. 

Draft copies of Appendix F (LMD checklist) and Appendix G (ECR-RMFD checklist) were provided by the 

technical advisor. Revisions were proposed to portions of the checklists that reference the following paragraphs in 

the NIST Handbook 44 LMD Code (Section 3.30.):

• S.1.6.4.1. Unit Price

• S.1.6.5.4. Selection of Unit Price

• S.1.6.6. Agreement Between Indications

• S.1.6.7. Recorded Representations

• UR.3.2. Unit Price and Product Identity
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D19

Discussion: 

The Technical Advisor, Mr. Buttler, presented first drafts of Appendices F and G to the Sector and explained that 

they were draft revisions to the NCWM Publication 14 LMD and ECR checklists which were developed in response 

to new LMD unit price posting and selection options and requirements adopted by the S&T Committee at the 2012 

NCWM Annual Meeting for inclusion in NIST HandbookB 44. Because of the short window of time between the 

finalization of the new requirements and Measuring Sector meeting, there was no opportunity for review of the 

drafts by any Sector members prior to the Measuring Sector meeting. Mr. Buttler explained that the Retail MotorFuel Dispensers Price Posting and Computing Capability (RMFD PPCC) Task Group, which had been responsible 

for developing the new options and requirements, was asked by the S&T Committee to continue their work by 

developing examples and interpretations that would aid weights and measures officials and industry in interpreting

and applying the requirements, and the Measuring Sector in updating the LMD and ECR checklists. However, that 

follow-up task is not yet complete and the Task Group has not yet set a target date for completion.

The NTEP Director, Mr. Jim Truex (NCWM), explained that in this situation, some urgent action was warranted to 

address the anticipated need for NTEP labs to be prepared for applications involving devices that would comply 

with some or all of the new options and requirements that were adopted. He asserted that these additional options 

were now going to be allowed in NIST Handbook44. Thus, the Measuring Sector and the NTEP labs could not 

afford to wait for delivery of the examples and interpretations by the RMFD PPCC Task Group, and must instead

take some immediate action to establish interpretations and guidelines for use in type evaluation. 

The Sector discussed the situation and agreed to do whatever was possible to complete the minimum updates to the 

checklists that would be needed to meet immediate needs in the short term without waiting for the anticipated 

deliverables from the RMFD PPCC Task Group. Furthermore, the Sector realized that additional revisions to the 

checklists might be required in the future in order to make use of the deliverables from the Task Group once they are 

provided. 

Mr. Jerry Buttler (North Carolina NTEP Lab) raised a question about stacked sales, “Will the console be able to 

retain all the necessary dispenser information long enough when there is a long delay between the fuel delivery and 

the customer action that qualifies for a post-delivery discount?” This scenario seems likely, as it is anticipated that 

shopping and purchasing items inside a convenience store is one likely action that would trigger a post-delivery

discount. The Sector discussed this and concluded that the requirements for stacked sales and for what must appear 

on the receipt when a post-delivery discount is applied would apply to these systems. F urthermore, the Sector 

concluded that design and use for compliance with these requirements must be addressed by the manufacturers and 

users/owners of these devices and systems if post-delivery discounts are to be offered. However, the further concern 

was raised as to whether the checklists fully address the need to assure that long delays in completing stacked sales 

do not present problems for some devices and systems. 

Mr. Chris Willeke (Bright Solutions, LLC) raised a concern that, for tax reporting purposes, the International Fuel 

Tax Association (IFTA) may require that the net unit price of the fuel be stated by trucking operations for all 

purchases. The concern was based on the potential scenario where a receipt from a fuel sale would include all the 

information required in the new NIST Handbook 44 paragraph S.1.6.8. “Recorded Representations for Transactions 

Where a Post-Delivery Discount(s) is Provided,” including the: total quantity, unit price, and total computed price 

shown at the dispenser prior to the post-delivery discount; an itemization of the post-delivery discounts to the unit 

price; and the final total computed price of the fuel sale. However, because the receipt is not required to include the 

final computed unit price paid for the fuel that includes all post-delivery discounts, it would require truck operators 

to do a substantial amount of additional calculations to compute the values when preparing tax reports. Mr. Rich 

Tucker (RL Tucker Consulting LLC) asked if the post-delivery discounts applied to the unit price would need to be 

reported or would the unit price at the pump be reported, since the discount would be applied after the fuel was 

delivered. Mr. Willeke consulted with some of his staff and later confirmed that the report that truck operators must 

submit does not require the unit price, only the net total computed price for the fuel. Learning this, the Sector 

agreed that the issue was resolved, since the net total computed price for the fuel is required to appear on the receipt.

After the above discussion, the group of volunteers listed below agreed to reconvene following the first day of the 

Sector meeting to work on the checklist drafts:

Gordon Johnson, Gilbarco, Inc.

During the evening session, Mr. Oppermann suggested that the order in which certain checklist items and code 

references appear in the LMD checklist needed to be reorganized in order to place these items in the correct section 

of the checklist and to ensure they are applied to all the intended types of devices. The Task Group relocated the 

code reference S.1.6.5.4. “Selection of Unit Price” and its associated checklist items from Section 8 “Computing” to 

Section 7 “Indicating and Recording Elements” in order to locate the checklist items that are related to the selection 

of unit price together with the code reference S.1.6.4.1. “Display of Unit Price” and its associated checklist items. 

The code reference S.1.6.8. “Recorded Representations for Transactions Where a P ost-Delivery Discount(s) is 

Provided” and its associated checklist items needed to be located in multiple locations to ensure that the checklist 

items are applied to general retail motor fuel dispensers, card-activated devices, and cash-activated devices, when 

appropriate.

The volunteers successfully completed their review and presented their results as shown in Appendices F and G the 

next day. 

Decision: 

The Sector reviewed the revised proposals and unanimously agreed to propose them as shown in 

Appendices F and G to the NTEP Committee for inclusion in NCWM Publication 14.

11. NCWM Pub 14, NTEP Administrative Policy Revision 

Source: 

NTEP

Background: 

NCWM is working to revise Pub 14, Administrative Policy to put it in a more logical order and more understandable 

form. The purpose is not to change the intent of the document, rather to realign and clarify sections as necessary.

Discussion: 

Mr. Truex explained that the purpose of the proposed revision of the Administrative Policy of NCWM 

Publication 14 was to streamline the document and to address aspects of the current version that some people had 

found confusing. He further explained that the proposal was not intended to change the meaning of any aspect of 

the policy, only to reorganize and clarify. Since the Administrative Policy section of NCWM Publication 14 is not 

the responsibility of any specific Sector to maintain, the modified draft version has been distributed widely to the 

members of all NTETC Sectors. Mr. Truex reported that all other Sectors have reviewed the draft and reported no 

major problems. Mr. Oppermann also reported having reviewed the draft and indicated his support. 

Mr. Truex requested that all recommendations and concerns from individuals, if there are any, be provided directly 

to him prior to the 2013 NCWM Interim Meeting, if possible. 

Decision: 

The Sector members agreed to provide any comments on the proposed revisions to the Administrative Policy 

of NCWM Publication 14 directly to Mr. Truex. 

ADDITIONAL ITEMS AS TIME ALLOWS:

The Measuring Sector was asked to provide input on the following measuring-related issues on its agenda if time 

permitted during the Sector Meeting. In the interest of brevity, the narrative for each item is abbreviated to the 

extent practical. Full descriptions of NCWM S&T Committee items can be found in the S&T Committee’s list of 

carryover items and its 2012 Final Reports.

12. Windshield Washer Fluid Vending Units

Source: 

Chris Willeke, Bright Solutions

Background: 

A manufacturer seeking preliminary guidance on requirements for windshield washer fluid vending units asked for 

input on the application of NIST Handbook 44 and NCWM Publication 14 to these devices. Specific language for 

NCWM Publication 14 and NIST Handbook 44 have not yet been developed.

Recommendation: 

The Sector was asked to consider the application and recommend the most appropriate path to address the following 

issues for windshield washer fluid vending devices:

• Determine the appropriate code section from NIST Handbook 44 that applies to this application and 

whether any changes or additions to either NIST Handbook 44 and/or NCWM Publication 14 are required.

• Determine what changes or additions to either NIST Handbook 44 and/or NCWM Publication 14 are 

appropriate to recognize the proposed method of dispensing without an indication of the total quantity 

delivered and with a time-out function. The submitter suggests using language that can be found in the 

California Type Evaluation Program (CTEP) standards for testing and certifying water vending units as a 

starting point. However, these standards do not address specifications or testing of the time-out function.

Discussion: 

Mr. Michael Keilty (Endress and Hauser) explained that this item is not a NCWM Publication 14 issue, but a 

manufacturer is seeking input from the sector on how the code would apply for an NTEP evaluation. The Sector did 

not object to hearing the item.

Mr. Chris Willeke (Bright Solutions, LLC) explained the system’s functioning and answered questions from other 

Sector members about how the device functions. The system is designed primarily to be installed on the island in

fueling stations near the motor-fuel dispensers. It delivers discrete pre-authorized quantities of windshield washer 

fluid through a hose and nozzle that is intended to be used by customers to fill the reservoir in their vehicle during 

fueling stops. The device is capable of meeting a 0.75 % tolerance and typically discharges product at a flow rate 

close to 1 gpm. 

As part of his presentation, Mr. Willeke shared a system diagram that included a totalizer and a Point of Sale (POS) 

display. Mr. Willeke explained that the totalizer does not return to zero or display the indications of total quantity, 

unit price, or computed price for each transaction that would be required to comply with the LMD Code. There is a

discharge valve on the nozzle that is controlled by the customer. The POS system is used solely to purchase and 

pre-authorize the delivery of a discrete pre-set amount (e.g., 1 gal). However, if the customer does not allow the full 

amount to be delivered through the discharge valve within a certain time limit, the device is automatically reset and 

the quantity that remains undelivered is forfeited by the customer. M r. Willeke also confirmed that there is no 

indication of the amount that was forfeited. T he time limit is measured from the time the transaction is first 

authorized and cannot otherwise be controlled by the customer. 

Mr. Willeke noted that the State of Wisconsin required this device to have an NTEP CC before it could be placed 

into commercial service. Mr. Willeke suggests that similar devices are in service now in some jurisdictions to vend 

water. The main difference between these devices and the proposed method is that water vending machines are 

designed to always deliver the full quantity of what was purchased into an empty container of known volume. 

Because water vending machines always dispense the full amount that was purchased, the selected preset amount 

can serve as the indication of the quantity that was delivered. Water vending machines have no customer-controlled

nozzle, so there is no need for a t ime-out function that resets the transaction, possibly retaining an undisclosed 

amount of undelivered product. H owever, no standards or test methods exist in NIST Handbook 44 or NCWM 

Publication 14 that could be employed to ensure that the time-out function of the windshield washer vending 

machine, as it is described, is operating as intended and not in a way that could facilitate fraud.
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D22

The NTEP labs were uncertain what code could be applied for NTEP evaluation because of some of the unique 

characteristics of the device. The CA DMS NTEP Lab described CTEP approval of water vending machines as the 

example of equipment that is perhaps most similar to the windshield washer fluid vending machine. Mr. John 

Roach (CA DMS NTEP Lab) explained that CA borrows from the Water Meters Code for tolerance values when 

they evaluate water vending machines for CTEP approval because there is no national code that would apply to 

these devices.

The Sector members made comparisons between the system that was described by Mr. Willeke and other 

commercial devices, including timing devices used in air compressors for filling tires, water vending machines, DEF 

dispensers, and slow flow liquid-measuring devices used to sell fuel additives. At the end of the discussion, the 

consensus was that the way that this system currently functions does not comply with any existing set of 

requirements in NIST Handbook 44. Many members of the Sector expressed opinions that the device would need to 

be modified to comply with the LMD Code in order to seek NTEP approval. 

Mr. Dennis Beattie (Measurement Canada) questioned whether the LMD Code could be applied to the device 

because of paragraph A.2.(e), which states:

A.2. Exceptions. – This code does not apply to:

: 

: 

: 

(e) devices used solely for dispensing a product in connection with operations in which the amount 

dispensed does not affect customer charges;

This would potentially be true, unless a customer decided to purchase more than the initial discrete amount, in which 

case the total customer charges would be incrementally increased based on the measurement of the device each time 

it reached the pre-authorized quantity and stopped until more was purchased. 

Mr. Truex offered an opinion that this is a method of sale issue. He added that the fuel additive device that was 

discussed earlier has a working display to comply with the LMD Code. Mr. Truex confirmed that there are no 

NTEP CCs on water vending machines. Mr. Truex suggested that this metering device does not clearly fit into any 

code in HB 44 and suggested contacting the NIST L&R experts for guidance. He stated that the recommendation 

Mr. Willeke received from WI to apply for an NTEP CC may have been incorrect and he will discuss the issue with 

Wisconsin Weights and Measures. 

Decision: 

There was no decision to be made by the Sector on this issue. The manufacturer expressed his gratitude to 

the Sector for considering the question of how to seek NTEP approval. 

13. Hot Water Meters

Source: 

Michael Dick, Norgas Metering Technologies, Inc.

Purpose: 

Include provisions for type evaluation and NTEP certification of hot water meters. 

Recommendation: 

Neither NCWM Publication 14 nor NIST Handbook 44 specifically address water temperature in the sections related 

to water meters. The Sector was asked to consider whether specific testing requirements or other information are 

needed in NCWM Publication 14 and/or NIST Handbook 44 to support NTEP evaluation, testing, and certification 

of hot water meters that are designed to operate continuously in the range from 80 °F to 140 °F. 

Background: 

Submeter applications exist where individual tenants share a co mmon water heating system. T o accommodate 

accurate measurement of the hot water consumed by each tenant, NTEP certified meters capable of measuring the 

water after it has been heated (in the range from 80 °F to 140 °F) are needed. 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D23

The submitter is developing a proposal to establish requirements for these devices and has asked the Sector for 

preliminary guidance. Sp ecific language for NCWM Publication 14 and NIST Handbook 44 has not yet been 

developed. The item was withdrawn by the submitter prior to the meeting; however, the Sector chose to discuss the 

item and determine if anyone else wanted to address the item.

Discussion: 

Mr. Roach explained that California issues CTEP CCs which specifically identify “hot water” meters and “cold 

water” meters on the CC. CTEP requirements for hot water meters reference the AWWA handbook.

Mr. Truex explained that the original submitter of this item was requesting a “hot water” meter designation on an 

NTEP CC. He further explained that NTEP cannot issue a CC for a “hot water meter” since NIST Handbook 44 

does not include a definition or requirements for “hot water meters.” The Water Meters Code in NIST Handbook 44 

currently imposes no specific temperature restrictions on ordinary water meters beyond the limitations stated by the 

manufacturer. The individual was satisfied when NTEP agreed to include water temperatures that were used during 

testing under the “test conditions” section of an NTEP certificate that recognizes the device as an ordinary water 

meter as defined in Section 3.36. of NIST Handbook 44. Mr. Truex added that the temperature information would

NOT appear on page 1 of the CC because stating this information on page 1 would imply something that has no 

basis in NIST Handbook 44. 

The Sector went on to discuss whether there is a general need for NIST Handbook 44 to recognize hot water meters 

separately and with a different set of requirements than standard “cold” water meters. Mr. Ralph Richter (NIST, 

OWM) shared that OIML R 49 “Water meters intended for the metering of cold potable water and hot water”

includes hot water meters and cold-water meters together. Mr. Andre Noel (Neptune Technology Group, Inc.) 

pointed out that some meters may be made of materials that are compatible with cold water, but not with hot water. 

Mr. Noel volunteered to raise this question with other water meter manufacturers to determine if any manufacturers 

are interested in developing this item as a proposal to the NCWM S&T Committee. 

Decision: 

The Sector agreed to carry over the item in the Additional Items as Time Allows Section to allow the water 

meter manufactures to determine whether it will merit further development.

14. Section 3.31. Vehicle-Tank Meters; Paragraph T.4. Product Depletion Test (S&T Carryover 

Agenda Item)

Source: 

2012 NCWM S&T Agenda. Original source is the Northeast Weights and Measures Association (NEWMA).

Background: 

The S&T Committee has been considering a proposal to modify the VTM Code to base the product depletion test 

tolerances on the meter’s maximum flow rate (a required marking on all meters), rather than the meter size (a 

required marking for meters manufactured beginning in 2009). This will enable more consistent application of the 

tolerances for older meters, which are not required to be marked with the meter size, and address an unintentional 

gap that allows an unreasonably large tolerance for smaller meters.

From 2009 t o 2011, the Committee repeatedly requested data to support or oppose the various proposals under 

consideration with little success. At the 2011 Annual Meeting, the Committee reiterated its need for data to evaluate 

the impact of any proposed tolerances changes. F ollowing that meeting, NIST Technical Advisor, Ms. Tina 

Butcher, on behalf of the Committee, distributed a request on NIST OWM Directors’ list serve asking weights and 

measures jurisdictions to submit data.

At the 2012 NCWM Interim Meeting, the Committee reiterated its position that tolerances for the product depletion 

test of a VTM should be based on the marked maximum flow rate of the meter rather than meter size. T he 

Committee considered the three options for modifying NIST Handbook 44, including two options presented in its 

Interim Agenda and a third option submitted by the MMA prior to the meeting. A summary of the three options is 

outlined in the following table. A second table illustrating examples of tolerances for common meter sizes and 

maximum flow rates is also included.

During its Open Hearings at the 2012 Interim Meeting, the Committee heard support for Option 3 from members of 

the MMA. The Committee also heard a comment from Mr. Ross Andersen, who submitted the original proposal. 

Mr. Andersen pointed out that the tolerances in Option 1 were the same as those that apply prior to modifying the 

tolerance to be based on meter size.

S&T Technical Advisor, Mrs. Tina Butcher, NIST OWM, reported that the Committee received product depletion 

test data from nine state and county weights and measures jurisdictions. Mrs. Butcher distributed a summary to the 

Committee as shown in the following two tables. Mrs. Butcher noted that assumptions were made about meter size 

in some instances where meter size and/or maximum flow rate were not both provided. The first table summarizes 

the number of meters tested along with a comparison of the number that failed the current and proposed tolerances; 

the data includes a breakdown of meters in three different flow rate categories.

At the 2012 NCWM Annual Meeting Open Hearings, Mr. Dmitri Karimov (Liquid Controls) speaking on behalf of 

the Meter Manufacturers Association, commented that, while MMA is aware that the Committee did not support 

MMA’s proposed “Option 3,” the MMA supports “Option 2” recommended by the Committee.

The Committee wishes to express its sincere appreciation to those jurisdictions that submitted data. The Committee 

discussed the data received and the summaries prepared by NIST OWM. The Committee recognizes that the data 

collected was not obtained under controlled conditions or as part of a structured survey or study; however, the data 

has been extremely valuable to the Committee in assessing the relative impact of the three options proposed. After 

discussing the comments and reviewing the summary of the data prepared by NIST OWM, the Committee agreed 

that Option 2 represents a reasonable compromise between the original proposal and the MMA’s proposal 

(designated Option 3 in the tables above). T he Committee acknowledged that this item has included multiple 

proposals up to this point and it is important for the Committee to designate a single option for consideration by the 

NCWM in order that this item can progress. Consequently, the Committee is deleting the other options and 

presenting Option 2 for consideration. B ecause this item has included multiple proposals up to this point, the 

Committee decided to designate this item as an Information Item and is asking for input on the proposal as shown in 

the Item Under Consideration prior to moving the item forward as a Voting Item. 

The Committee asks the regional weights and measures associations and industry for input regarding whether or not 

the proposed changes are ready for adoption in the next NCWM cycle.

Discussion: 

Members of the MMA who were present at the Sector meeting shared that, although they still recommend “Option 

3” as it was proposed to the S&T Committee, the MMA understands the deliberations of the S&T Committee and 

reluctantly supports the item moving forward as Option 2. The meter manufacturers in the MMA have discussed the 

latest position of the S&T Committee and agree they can “live with” and will support Option 2 in order to move the 

item forward. 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

NTEP - D27

The MMA’s reluctance to support Option 2 was based on a concern that the tolerances in Option 2 are still too tight 

on smaller meters and they had offered “Option 3” to resolve this concern. The MMA believes that the failures of 

the smaller meter sizes in the data are mainly measuring system failures, not meter failures.

Decision: 

The Measuring Sector discussed this item and learned that the MMA is supporting the item. The Sector, 

therefore, recommends that the S&T Committee move the item forward as a Voting Item using the language 

as described in Option 2.

NEXT MEETING:

The Sector discussed the time and location of the next meeting and all agreed to continue to keep the meeting in

association with the SWMA. A proposal to hold the Sector meeting following the SWMA was discussed, but the 

Sector decided to keep the meeting prior to the SWMA, because the time following the SWMA is not available for 

some members. 

Technical Advisor’s Note: Since the Sector meeting, Mr. Keilty has received information that the 2013 SWMA 

Annual Meeting is scheduled to take place from October 7 - 9, 2013, in Charleston, West Virginia, at the 

Embassy Suites Hotel. The Measuring Sector Meeting is likely to be scheduled on October 4 - 5, 2013, in that 

location.

Code Reference: G-S.5.2.3. Size and Character

Digits used for comparable values must be uniform in size and character, but subordinate values may be displayed in 

different and less prominent digits than more significant values. The latter more likely occurs on analog devices. In 

digital indications, the digits are usually of uniform size throughout a particular display. The size of digits may differ 

for different quantities, for example, the quantity and unit price digits may be smaller than the total price digits.

designated.

Yes  No  N/A 

Code Reference: G-S.5.2.4. Values Defined

Code Reference: G-S.5.4. Repeatability of Indications

The quantity measured by a device shall be repeatable within tolerance for the same indication. One condition that may 

create a problem is that the value of the quantity division may be large relative to the tolerance. A delivery must be 

within tolerance wherever the delivery is stopped within the nominal indication of the test draft. Meters that may be at 

the tolerance limit may be out of tolerance at an extreme limit of the nominal quantity indication.

Code Reference: G-S.8. Sealing Electronic Adjustable Components, and Provision for Sealing of Adjustable 

Components or Audit Trial

2.29. Electronic adjustable components that affect the performance of a device shall 

provide for an approved means of security (e.g. data change audit trail) or for 

physically applying a s ecurity seal. T hese components include the following: 

(1) mechanical adjustment mechanism for meters, (2) the electronic calibration 

factor and automatic temperature compensator for electronic meter registers, (3) 

selection of pressure for density correction capability and correction values, and 

(4) pulser setting and gallon/liter conversion switches when they may 

accidentally or intentionally be used to perpetrate fraud.

Yes  No  N/A 

The following philosophy and list of sealable parameters applies to provision for sealing all liquid-measuring devices.

 

An electronic data audit trail is a means of allowing a weights and measures inspector to review how many times any 

electronic adjustment, which affects the accuracy of a volume measurement has been changed. T he information 

contained in the audit trail shall consist of a cumulative and non-destructible number (even if a power failure occurs) 

which increments each time any of the adjustments required to be sealed have been changed. The electronic data audit 

trail information shall be capable of being recalled by the official on the main display of the device.

As a minimum, devices which use an audit trail to provide security for sealable parameters shall satisfy the 

following criteria and shall use the format set forth in Appendix A of the checklist for Liquid-Measuring 

Devices.

Sub-appendix A – Agenda Item 1-Draft Checklist for Testing Electronic Digital Indicators

NTEP - D / A6 

Philosophy for Sealing 

Typical Features to be Sealed

Principles for Determining Features to be Sealed

The need to seal some features depends upon:

• The ease with which the feature or the selection of the feature can be used to facilitate fraud; and

• The likelihood that the use of the feature will result in fraud not being detected.

Features or functions which the operator routinely uses as part of device operation, such as setting the unit prices on 

dispensers and maintaining unit prices in price look-up codes stored in memory, are not sealable parameters and 

shall not be sealed.

If a parameter (or set of parameters) selection would result in performance that would be obviously in error, such as 

the selection of parameters for different countries, then it is not necessary to seal the selection of these features.

If individual device characteristics are selectable from a "menu" or a series of programming steps, then access to the 

"programming mode" must be sealable. (Note: If an audit trail is the only means of security, then the audit trail 

shall update only after at least one sealable parameter has been changed; simply accessing the sealable parameters 

via a menu shall not update the audit trail.)

If a physical act, such as cutting a wire is required to change a parameter setting and physically repairing the cut is 

required to reactivate the parameter, then this physical repair process would be considered an acceptable way to 

select parameters without requiring a physical seal or an audit trail.

Typical Features and Parameters to be Sealed

The following provides examples of configuration and calibration parameters that are to be sealed. The examples 

are provided for guidance and are not intended to cover all possible parameters. 

Calibration Parameters: Calibration parameters are those parameters whose values are expected to change as a 

result of accuracy adjustments. Examples include the following.

1. Measuring element adjustments where linearity corrections are used, e.g., flow rate 1 and meter factor 1, flow 

rate 2 and meter factor 2, etc.

2. Mass flow meter adjustments for zero adjustments (not simply setting the display to zero) and span settings.

Configuration Parameters: Configuration parameters are those parameters whose values are expected to be 

entered only once and not changed after all initial installation settings are made. Examples include the following.

1. Octane or other blend setting ratios (optional in Canada at this time)

2. Temperature, pressure, density, and other sensor settings for zero, span, and offset values

3. Measurement units (in Canada, only if not displayed or printed on the primary register)

4. Temperature compensation table, liquid coefficient of expansion, or compressibility factors or tables

5. Liquid density setting (in Canada, only if not displayed or printed on the primary register) and allowable liquid 

density input range

6. Vapor pressures of liquids if used in calculations to establish the quantity

7. Meter or sensor temperature compensation factors

8. False or missing pulse limits for dual pulse systems (Canada only)

9. On/off status of automatic temperature, pressure, or density correction

10. Automatic or manual data input for sensors

11. Dual pulse checking feature status on or off

12. Flow control settings (optional in Canada)

13. Filtering constants

Liquid-Measuring Device Features and Parameters

Typical Features or Parameters to be Sealed Typical Features or Parameters Not 

Required to be Sealed

Measuring element adjustment (both mechanical 

and electronic)

Analog-to-digital converters

Linearity correction values Quantity division value (display resolution)

Measurement units (e.g., gallons to liters) Double pulse counting

Octane blend setting for retail motor-fuel 

dispensers

Communications

Any tables or settings accessed by the software or 

manually entered to establish the quantity (e.g., 

specific gravity, pressure, etc.)

Density ranges

Pulsers

Signal pick-up (magnetic or reluctance)

Temperature probes and temperature offsets in 

software

Pressure and density sensors and transducers

Flow control settings, e.g., flow rates for slowflow start, quantity for slow-flow start and stop

Temperature compensating systems (on/off)

Differential pressure valves

As a point of clarification, the flow control 

settings referenced above are those controls 

typically incorporated into the installations of 

large-capacity meters (wholesale meters). The 

reference does not include the point at which retail 

motor-fuel dispensers slow product flow during a 

prepaid transaction to enable the dispenser to stop 

at the preset amount.

Note: The above examples of adjustments, parameters, and features to be sealed are to be considered "typical" or 

"normal." This list may not be all-inclusive. Some parameters other than those listed, which affect the metrological 

performance of the device, must be sealed. If listed parameters or other parameters, which may affect the 

metrological function of the device, are not sealed, the manufacturer must demonstrate that all settings comply with 

the most stringent requirements for the application of the device (i.e., the parameter does not affect compliance with 

Handbook 44).

Appendix D – Sub-appendix B

Draft Measuring Element vs. Register Evaluation Criteria 

(Technical Policy T)

Agenda Item 1

Many different kinds of electronic indicators are available for liquid measurement. Gas pumps, 

vehicle tank meters, and wholesale meters are common applications used. In some cases the 

same indicator can be used in multiple applications. Below are some guidelines and test 

procedures to be incorporated into Pub 14 to allow the manufactures to pretest to and to make 

uniform the testing for the NTEP labs for this technology. 

T. Testing required for Electronic Indicators used with Measuring Elements.

If the indicator and measuring element are built into the system as a whole device then they are 

approved as a system and listed as a single device on the certificate.

If the indicator or measuring element are separable and can be used with other approved and 

compatible equipment then the following needs to be considered: 

If the Electronic Indicator and Measuring Element both have a CC then the two do not need 

evaluation provided new features that would have a metrological effect have not been added to 

the existing equipment. Even though they both have a CC they still need compatibility 

verification i.e. approved and compatible. This can be verified at the local level of compliance. 

If neither the Electronic Indicator or Measuring Element do not have a CC then full testing will 

be performed as per Pub 14 permanence testing for Electronic Indicating Element (20-30 days of 

significant use) and Measuring Element (through put). 

If the Electronic Indicator does not have a CC but the Measuring Element has a CC then the 

Register will go through the 20-30 day permanence test. 

If the Electronic Indicator has a CC but the Measuring Element does not then the measuring 

element will go through the associated through put as per the permanence for that particular 

technology. 

Upon verification of the local authority, the NTEP lab may allow the local authority to conduct 

one phase of the evaluation, at the NTEP labs direction and control.

Testing considerations for the electronic indicator:

Sub-appendix B – Element vs. Register Evaluation Criteria (Agenda Item 1)

NTEP – D / B2 

1) Multi-point Calibration: Some of the newer indicators have the optional single point or multipoint calibration. Multi-point calibration associates multiple meter calibration factors with 

different flow rates. Meter field testing at the local level is usually at the maximum and 

minimum flow ratings of the meter. Without the ability to print or view the multi-point 

parameters a meter could be calibrated with an intentional erroneous factor and could go 

undetected. The only other way would be to test at random flow rates and depending on the 

number of calibration points fraud could still be undetected; i.e. a meter factor that would 

allow an out of tolerance error for a delivery flow rate other than customary test flow rates.

Some manufactures have provided a method for weights and measures to view or print the 

calibration information without having to break any seals. This viewing or printing capability 

should be incorporated into Pub 14 (maybe HB44 too?) as a tool for W/M to be able to detect 

the possibility of fraud on these systems. It would also allow for manufactures to be aware of 

this and build this into their systems that have multi-point calibration. 

2) Tests for temperature compensation:

a) Temperature test at cold temperature and verify correction.

b) Temperature test at hot temperature.

c) Temperature test at field site temperature.

List temperature range tested and type of probe tested on certificate.

3) Tests for pulser/encoder rotation speed: 

a) Induce pulses and/or frequency at maximum to determine limitations of device. 

b) Induce pulses and/or frequency at minimum to determine limitations of device. 

List limitations on certificate.

4) Tests for power failure: Indicators are capable of operating on different voltages. May want 

to consider weighing device testing for electronic indicators and information listed on 

certificate.

a) Test through AC voltage range

b) Test through DC voltage range 

c) Power failure

5) Tests for computation, if capable. 

a) Test below $.999/gal. 

b) Test above $1.00/gal. 

c) Test above $2.00/gal. 

d) Test at maximum unit price capability.

6) Tests for agreement of indications between indicator and totalizer if a totalizer is provided.

Proposal to NTEP:

Program for Approval of Meters on Liquids 

other than Petroleum Products.

Subject: Type Evaluation and Approval of Positive Displacement Meters for

Liquids other than Refined Petroleum Products

The use of positive displacement meters for the accurate measurement of 

petroleum products throughout the entire petroleum distribution system has had a 

long history of success.

These meters or variants of them, with minor variations of materials of 

construction in some cases, have the demonstrated ability to handle a wide 

spectrum of liquids in other areas of industry and commerce as well. Some of 

these applications are not familiar to many people. Therefore the ability to judge 

their effectiveness, especially when submitted for weights & measures type

evaluation and approval for use in trade, is a cause for concern.

The response is generally to require that insitu accuracy and permanence tests be

run at a field test site. This approach is cautious and conservative, but also 

costly to the equipment manufacturer and wasteful of Weights & Measures

officials time. Indirectly, it tends to discourage use of efficient handling of 

liquids by meter measurement systems in many commercial areas because of 

protracted approval costs.

Sub-appendix C – 1991 Product Families Table Proposal – Liquid Controls (Agenda Items 2-4)

NTEP - D / C4 

September 23, 1991

There are hundreds, even thousands, of liquids that are suitable for meter 

measurement. What is proposed herewith is a workable, reliable approach for 

evaluation that will yield results that will validate the capability of the meter

on a range of liquids and conserve valuable time and labor in the process.

This approach is dependent on two general concepts:

a) The classification of meters by materials of construction b)

The classification of liquidsinto families or groups

Materials of Construction

Classification of meters by materials of construction is as noted earlier in this 

proposal a means to adapt the meter to the liquid environment in which it

will be used. Matters of corrosion, lubricity, and the like are dealt with by the 

manufacturer in order to optimize the construction for the intended service. 

For a given meter manufacturer, meter measuring elements in design, size,

and shape are unchanged, but the materials are selected to

make the unit function effectively in the liquid group in which it will be used.

Liquid Controls Corporation has developed 15 classes that give optimum 

performance in the various liquid groups at an effective cost level. (Refer to 

Appendix A for a listing of these classes.) The number and make up of the 

classes may vary from manufacturer to manufacturer.

Liquid Groups or Families

It is possible to classify and group liquids in a number of ways including for 

example the broad general groups of: 
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary – 

Sub-appendix C – 1991 Product Families Table Proposal – Liquid Controls (Agenda Items 2-4)

NTEP - D / C5 

September 23, 1991

Inorganic Liquids (usually water based solutions of acids, bases, or their 

salts - liquids that are likely to be corrosive in varying degrees due to 

their dissociation or ionization in water).

or

Organic Liquids (usually non-dissociated non-ionized homogenous and noncorrosive).

However, for practical reasons in matching not only chemical characteristics, but 

also physical characteristics such as viscosity, vapor pressure, whether clear and

homogenous, specific gravity, whether or not they contain solid particulate

matter, etc. another method of classifying is desirable.

A practical classification method that has worked well in the past in the 

industrial metering arena uses the following Families:

Water

Hydrocarbons/Petroleum Products

Alcohols, Glycols, and water mixtures thereof

Solvents (General) Solvents

(Chlorinated) Compressed

Liquified Gases

LPG

NH3

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

Sub-appendix C – 1991 Product Families Table Proposal – Liquid Controls (Agenda Items 2-4)

NTEP - D / C6 

Agricultural Liquids

Liquid Feeds

Clear Liquid Fertilizers

Suspension Fertilizers

Herbicides

Chemicals

These are groups of liquids that have a high degree of commonality in 

chemical and physical properties and are therefore similar in metering 

characteristics.

Appendix B is a chart showing the Liquid Families along with lists of 

examples of the various groups and their key parameters that influence 

meterability. These examples cover the range of properties within a group, 

but the list is not inclusive of all liquids in a given group in most cases.

Appendix B also includes a chart matching meter class materials of 

construction with the various Liquid Families for optimum compatibility.

In view of the above, it is our specific recommendation that the following 

approach be used for the testing, evaluation, and approval of meters in the 

numerous application areas possible. We feel that this will enable expanded 

use in trade of a very efficient method of moving and handling liquids

without undue approval cost to the manufacture nor undue use of the limited

Weights and Measures labor resources:

September 23, 1991

A. Application would be made and a meter would be submitted for 

approval on a specific family of liquids.

From the list of liquids, constituting the family(s), two liquids 

representative of the high and low of the key parameters would be selected

for use in the test. If the meter successfully performed on tests of accuracy

and permanence on the two extreme liquids it would be approved for use 

on all liquids in that family(s).

B. If meters of a given class of construction successfully passed all 

evaluation criteria, meters of a higher grade of construction would also be 

granted approval if so requested at the time of application by the 

manufacture if the design and size of the devices were the same. An 

example of this might be:

If a meter of ferrous construction were submitted and approved then 

the same device constructed of stainless steel could likewise be approved 

without retesting if so requested by the manufacturer.

C. For a given Meter Class having a range of sizes or capacities

(such as 1112", 2", 3", 4" and 6"), if the middle unit of these (e.g. 3") were

submitted for type evaluation and passed all requirements of accuracy and 

permanence, then the entire series of meters would be approved if so 

requested by the manufacturer at the time of submittal. D. For a 

smaller range of size or capacity, meters one size smaller and one size larger 

than the meter submitted for actual approval test would be also approved 

upon completion of successful test of the submitted unit if the 

manufacturer so requested this at the time of submittal.

Sub-appendix C – 1991 Product Families Table Proposal – Liquid Controls (Agenda Items 2-4)

NTEP - D / C8 

September 23, 1991

This is predicated on the fact that the design of the meter is 

identical in all respects only scaled down or up in size for capacity.

An example of this might be:

If a 2" meter were submitted for approval, upon successful 

completion of testing the next smaller size, 1 1/2" meter, and the next larger size, 

3" meter, would likewise be given approval.

This proposal is submitted as a request to develop and establish testing

policy guidelines that will enable approvals sought under NTEP to have a 

standardized set of procedures and requirements that are practical in terms of 

costs and manpower utilization.

In conclusion, in view of recent efforts to assure competitive relationships in 

world trade, the requirements developed for NTEP approvals of meters should be 

no more severe or restricting than those required by

international regulatory bodies (e.g. ECC in Europe and OIML).

1 Viscosity (dynamic) is measured in centipoise. Kinematic viscosity is measured in centistokes. Source for some of the viscosity value information is the 

Industry Canada – Measurement Canada "Liquid Products Group, Bulletin V-16-E (rev.1), August 3, 1999." 

 centistokes (10-6 m2

/s) = centipoise (10-3 kg/m·s) ÷ density (kg/m3) OR centistokes (cSt) = 1.002 × centipoise (cP) ÷ density (SG)

2 The specific gravity of a liquid is the ratio of its density to that of water at standard conditions, usually 4 °C (or 40 °F) and 1 atmosphere. The density of 

water at standard conditions is approximately 1000 kg/m3 (or 998 kg/m3

). The specific gravity of a gas is the ratio of its density to that of air at standard 

conditions, usually 4 °C (or 40 °F) and 1 atmosphere.

7. Indicating and Recording Elements

Code Reference: G-S.5.1. and G-UR.1.1. General

Indicating elements must be appropriately designed and adequate in amount. Specifically, a device must have 

sufficient display capacity to indicate the quantities and total prices, if it applies in the normal encountered 

specific application. Electronic devices shall either have sufficient display capacity to indicate the normal 

quantities and money values or automatically stop the delivery before exceeding the display capacity of either 

the quantity or total price. Analog indicating elements are required to have sufficient display capacity, or the 

device is not suitable for the application. This consideration may apply when evaluating a system that may be 

used in either a truck stop or an automobile service station.

7.1. Analog dispensers shall have adequate display capacity for the 

application.

Yes No N/A

7.2. An electronic digital indicating element shall either:

7.2.1. Have adequate display capacity for the application. OR Yes No N/A

7.2.2. Automatically stop the delivery before exceeding the maximum 

quantity or maximum total price that can be indicated.

Yes No N/A

Code Reference: G-S.5.2.2. Digital Indication and Representation; S.1.6.6. Agreement Between 

Indications

Basic operating requirements for devices are that:

• All digital values of like value in a system shall agree.

• A digital value shall agree with its analog representation to the nearest minimum graduation.

• Digital values shall round off to the nearest digital division that can be indicated or recorded.

• When a digital zero display is provided, the zero indication shall consist of at least one digit to the left and 

all digits to the right of the decimal point.

Due to limitations of some of the technologies used to transmit information from dispensers to service station 

consoles, some exceptions to these rules have been given to the indications on retail motor fuel dispensers and 

service station consoles. Exact agreement of digital quantity values is not required if only total price 

information is sent from the dispenser to the console. In these cases, the console calculates the quantity from 

the unit price set in the console. Consequently, the quantity indicated on the console may not agree exactly 

with the quantity indicated on the dispenser. However, if the console prints a customer receipt, then the 

quantity times unit price must equal the total price on both the dispenser and the printed receipt. In 2012, 

provisions were added to allow systems to apply post-delivery discounts. In cases where a system applies a 

post-delivery discount(s) to a fuel’s unit price through an auxiliary element, the exception mentioned above 

does not apply and, therefore, the total volume quantity of the delivery shall be in agreement between all 

elements in the system. See LMD Code S.1.6.6.

Previously, the service station console was considered an auxiliary indication and did not have to satisfy the 

mathematical agreement requirement for money values (G-S.5.5.) A non-retroactive requirement effective 

January 1, 1988 requires all service station consoles installed after January 1, 1988 (not just new models) to 

satisfy the mathematical agreement of money values requirement (S.1.6.6.) The money value indication prior 

to the application of any post-delivery discount for dispensers and consoles must agree for all installations, 

both old and new.

For those systems consisting of a console and dispensers and equipped with pre-set volume, the dispenser 

must deliver at least the pre-set volume; it c annot deliver less. For example, if the console sends only the 

money equivalent of the pre-set volume to the dispenser, the dispenser shall deliver at least the pre-set 

volume. It may not stop at the first quantity amount that results in mathematical agreement with the money 

value equivalent of the pre-set volume if the quantity indication is less than the pre-set volume. Similarly, if a 

money value is pre-set, the dispenser is not properly designed if it always stops at the lowest quantity value 

that provides mathematical agreement with the pre-set money value.

Tests for agreement of digital values shall be performed in the post pay, prepay money, and pre-set volume 

modes. Agreement should be checked at several unit prices including the maximum unit price and with the 

dispenser operating at its maximum flow rate.

indications and must agree prior to the application of any post-delivery 

discount.

motor fuel dispenser. When a system applies a post-delivery discount(s) to 

a fuel’s unit price through an auxiliary element, the total volume of the 

delivery shall be in agreement between all elements in the system.

7.8.1. In systems that do not apply a post-delivery discount, the quantity 

values indicated or recorded on a co nsole, electronic cash 

register, or other auxiliary indicating or recording element may 

differ, however, for all systems:

Discount Pricing

NIST Handbook 44 requires that, except for dispensers used for fleet sales, other price contract sales, truck 

refueling (e.g., truck stop dispensers used only to refuel trucks), when a product or grade is offered for sale at 

more than one unit price through a computing device, the selection of the unit price shall be made prior to 

delivery using controls on the device or through the deliberate action of the purchaser using: 1) controls on 

the device; 2) personal or vehicle mounted electronic equipment communicating with the system; or 3) verbal 

instructions. 

Should the customer elect to use another method of payment following completion of delivery, the console 

may be used to recalculate the total price  provided the dispenser complies with all applicable NIST 

Handbook 44 requirements. For example, the customer selects the credit card unit price on the dispenser and 

dispenses product at that unit price. However, the customer discovers that he forgot his credit card and decides 

to pay cash. In this case, the console might be used to calculate the total price at the cash unit price. In keeping 

with the intent of National Conference on W eights and Measures action in 1989 t o require dispensers to 

calculate at all unit prices for which a product is offered for sale, it is anticipated that the console would be 

required to recalculate the new total price using the formula (quantity x unit price = total price.) 

Except for fleet sales and other contract sales, a receipt providing the total volume, unit price, total computed 

price and product identity shall be available through a built-in or separate recording element for all 

transactions conducted with point-of-sale systems or devices activated by debit cards, credit cards, and/or 

cash. (Code Reference S.1.6.7) The recorded and displayed total fuel price on the receipt and dispenser, 

respectively, shall agree.

Selectable Unit Price Capability

Selectable unit price capability is a design feature that permits the customer to select the unit price for a 

particular transaction at the time of sale. A dispenser may then allow the unit price for a delivery to be

selected from two or more unit prices through the deliberate action of the purchaser using: 1) controls on the 

device; 2) personal or vehicle mounted electronic equipment communicating with the system; or 3) verbal 

instructions. 

If the customer selects the unit price at the dispenser (e.g., cash or credit price), the selection may be made at 

any time prior to the start of product flow. The dispenser operating handle may be on when the selection is 

made. A system shall not permit a change to the unit price during delivery of product.

After a transaction is completed, the unit price displayed at the dispenser may be changed to a base unit price. 

However, the quantity and total price must be displayed on the face of the dispenser for at least 5 minutes or 

until the next transaction is initiated. Any display of quantity, unit price, and total price that does not 

mathematically agree occurs between transactions. This is permitted (in response to demands of device users) 

because the displayed values between "transactions" are not "significant" relative to the actual delivery 

process (transaction.)

The displayed unit price may revert to the base unit price immediately after the completion of a transaction, 

defined as the time the delivery has been terminated and payment has been settled. The payment may be 

automatic if the delivery is to a pre-paid amount. If the sale is prepaid, the delivery is considered terminated 

after the "handle" is in the off position or after the nozzle has been returned to the designed hanging position. 

This will allow the customer adequate time to observe that the prepaid amount has been reached. If the 

delivery stops short or overruns a prepaid amount, settling the payment means that money is either refunded 

or collected from the customer and the transaction is "cashed out" by the console operator.

In the case of invoice billing systems, such as card-lock or key-lock systems which compute the total sale 

price, it is considered not appropriate for the displayed unit price to revert to the base unit price immediately 

following a t ransaction. Because a r eceipt for the transaction may not be available, the customer must be 

allowed an adequate period of time following the delivery to record the transaction information. The 

transaction unit price must be displayed for at least 30 seconds, and the total price and the quantity must be 

displayed for at least 5 minutes following the completion of the delivery or the start of the next transaction. 

The delivery is considered complete after the "handle" is off or the nozzle has been returned to its designed 

hanging position.

7.12. A dispenser may be equipped with means for selecting more than one unit 

price, provided that the selected unit price cannot be changed after the 

initial flow begins.

Yes No N/A

7.13. The selected unit price must be made clearly evident on the dispenser. Yes No N/A

7.14. Once selected the unit price cannot be changed by the operator at the 

console prior to or during the delivery.

Yes No N/A

7.15. The selected unit price displayed at the dispenser prior to the delivery of 

product must be continuously displayed at the conclusion of the delivery 

by moving the operating mechanism to the "off" position, until the start of 

the next transaction by:

7.15.1. Movement of the operating mechanism to the "on" position. OR Yes No N/A

7.15.2. "Authorization/Approval" by the console operator, whichever 

occurs first.

Yes No N/A

7.16. When a delivery is completed, the total price and quantity for that 

transaction shall be displayed on the face of the dispenser for at least 5 

minutes or until the next transaction is initiated by using controls on the 

device or other user-activated (e.g., customer-activated) controls.

Yes No N/A

7.17. In a system where a base unit price is automatically displayed on the 

dispenser after the completion of a transaction (e.g., product is dispensed 

and payment is settled), the dispenser may display the values for quantity, 

unit price, and total price that do not result in a mathematically correct 

equation. That is provided when the total price value displayed is divided 

by the quantity value displayed, the result is a unit price that is "posted"

for a particular kind of transaction.

Credit Card- or Debit Card-Activated Retail Motor Fuel Dispenser

On card-activated retail motor fuel dispensers, the customer authorizes the 

dispenser by inserting the card or swiping the card through a slot. On credit card

15. Card-Activated Retail Motor Fuel Dispensers

Code Reference: G-S.2. Facilitation of Fraud

Accidental or intentional fraud causes great concern when customers use card-activated systems in service 

stations, bank-card-activated systems directly access bank accounts. The following criteria and test procedures 

apply to card-activated retail motor fuel dispensers.

A card-activated system shall authorize the dispensing of product for not more than three minutes for the time 

between authorization and "handle on" at the dispenser. It shall properly record transactions on the appropriate 

card account.

When a card-activated system is subjected to power loss of greater than 10 seconds, the dispenser shall deauthorize. Because systems may be installed with separate power lines to the console, card reader, and 

dispenser, tests should be run with power failures to different parts of the system to evaluate the potential for 

accidental or intentional errors. The appropriate device response depends when the power loss occurs during 

the delivery sequence.

15.1. The dispenser must de-authorize in not more than three minutes if the pump 

"handle" is not turned on.

Yes No N/A

15.2. If the time limit to deactivate a dispenser is programmable, it s hall not 

accept an entry greater than three minutes.

Yes No N/A

15.3. When a power loss greater than 10 seconds occurs after the pump "handle" 

is on, the dispenser must de-authorize.

Yes No N/A

15.4. When there is a loss of power, but the pump "handle" is not on, the 

dispenser must de-authorize in not more than three minutes.

Yes No N/A

16. Test Methods for Card-Activated Retail Motor Fuel Dispensers

16.1. Authorize the dispenser and, with the pump "handle" on, interrupt power to 

any part (or all) of the system. The pump should deauthorize immediately. 

Specifically:

16.1.1. Authorize with a card and turn the "handle" on. Power down 

briefly, then restore power. Try to dispense product: the dispenser 

must not dispense because the power failure should have deauthorized the dispenser.

Yes No N/A

16.2. Authorize the dispenser using a card (leaving handle off); wait more than 

three minutes, and try to start the dispenser. It should not start because the 
NTEP Committee 2013 Final Report

authorization should have timed out. Specifically:

16.2.1. Authorize with a card, but do not turn the "handle" on. Power 

down for more than three minutes, and then restore power. Try to 

dispense product; the dispenser should have "timed-out" and not 

dispense.

Yes No N/A

16.2.2. Authorize and dispense with card #1. Allow the system to time 

out and de-authorize (if it does). Do not turn off the "handle." 

Authorize and dispense with card #2. The transactions shall be 

properly recorded for each card.

16.2.5. Authorize with card #1 (do not turn the "handle" on) and interrupt 

power for at least 10 seconds. This should de-authorize the 

dispenser. Resupply power; turn the "handle" on; try to dispense. 

The dispenser shall not deliver product.

Yes No N/A

Note: The term "handle" generically refers to the handle, flapper, start button, 

on/off switch, or other mechanism used to activate or deactivate the dispenser.

16.2.6. Authorize with card #1; turn the "handle" on, and then interrupt 

power. This should de-authorize the dispenser. Resupply power 

and authorize the dispenser with card #2. Then, complete a 

delivery. Verify that the transaction is charged to card #2.

Yes No N/A

Note: This test is not required if the device under test complies with paragraph 16.1.

Liquid Measuring Devices – Checklists and Test Procedures

for Cash-Activated Retail Motor Fuel Dispensers

The following criteria and test procedures apply to cash-activated retail motor fuel dispensers. Tests using 

various denominations of bills accepted by the cash acceptor should be performed.

Certificates of Conformance will cover the use of the cash acceptor option at both attended and unattended 

stations. Cash Acceptors which are used at unattended locations must meet the marking requirements of 

paragraph G-UR.3.4. Responsibility, Money-Operated Devices shall be clearly and conspicuously displayed 

on the device or immediately adjacent to the device information detailing the return of monies paid when the 

product cannot be obtained.

17. Code Reference: S.1.6.2. Provisions for Power Loss 

Even if power is interrupted during a delivery, it is still necessary to correctly complete all transactions in 

progress at the time of the power interruption. In the event of a power loss, the information needed to 

complete any transaction in progress at the time of the power loss (such as the quantity and unit price, sales 

price, or amount of money already inserted into the cash acceptor) shall be determinable for at least 15 

minutes at the dispenser or at the console or journal printer if the console or journal printer is accessible to the 

customer.

All portions of the transaction must be accounted for in order to complete the transaction. This information 

would include the following: (1) the total amount of money that was inserted into the device prior to the 

power interruption, (2) the amount of product already dispensed (which should be available from the 

dispenser and which must comply with the requirements of S.1.6.2., (3) and any bill that has been inserted but 

has not yet been recognized by the cash acceptor.

Note: For bills that have not yet been drawn into the cash acceptor to the point that the bill is no longer 

visible, it is assumed that the information on the bill denomination can be obtained from visual examination.

Various methods may be used to recall specific portions of the transaction depending on how the basic system 

operates. For example, systems that can print a record of the amount fed into the machine as each bill is fed 

into the device maintain an ongoing record of bills recognized by the system. Other systems may not print a 

receipt until the end of the transaction, so the information is recalled on a journal printer accessible to the 

customer or can be recalled on the cash acceptor display.

Check to see what happens when the power is interrupted at different points of the transaction. Note what 

occurs at the points where power is interrupted, what information is provided to the customer on the receipt, 

audibly and visually in the form of instructions or error messages. Because systems may be installed with 

separate power lines to the console, card reader, and dispenser may be installed, tests should be run with 

power interruptions to different parts of the system to evaluate the potential for accidental or intentional 

errors. The appropriate device response depends upon when the power loss occurs during the delivery 

sequence.

17.1. Systems with Battery Back-up or Uninterruptible Power Supply or 

Equivalent - Some systems are equipped with a b attery back-up or an 

uninterruptible power supply (or equivalent) which allows a transaction to 

continue in the event of a power loss. For such systems, the transaction in 

progress at the time of a power interrupted must continue as if no power 

interruption had occurred (or comply with the requirements for systems not 

equipped with a battery back-up.) That is, all bills (including bills being fed 

into the device at the time of the power loss) must be correctly accounted 

for, and the quantity and total sale amounts must be mathematically correct. 

Yes No N/A
NTEP Committee 2013 Final Report

Appendix D – NTETC 2012 Measuring Sector Meeting Summary

Sub-appendix F – Liquid Measuring Devices (Agenda Item 10)

NTEP - D / F18

Check these systems by interrupting power at several points in the 

transaction to ensure that all information (total price, quantity, 

mathematical agreement, and total dollar amount inserted by the customer) 

is accounted for correctly.

All Other Systems: To check the operation of systems not equipped with 

a battery backup, uninterruptible power supply, or equivalent, interrupt 

power as described below. As noted earlier, if separate power lines 

supply different components in the system, interrupt power to different 

parts of the system.

17.2. When one or more bills has been accepted and registered by the device, but 

product has not yet been dispensed, at least one of the following criteria 

must be met to ensure that this information can be recalled in the event of a 

power interruption:

17.2.1. The denomination of the bill must be printed by the printer on the 

device as the device recognizes the bill. (The printed receipt must 

be available to the customer.)

Yes No N/A

17.2.2. The denomination of each bill must be printed by a journal or 

other printer accessible to the customer as each bill is recognized 

by the device. 

Yes No N/A

17.2.3. The running total display must be capable of being recalled for at 

least 15 minutes.

Yes No N/A

17.2.4. Means provided to enable the customer to retrieve the money 

inserted into the device (e.g., a button which can be used during a 

power interruption to eject the money inserted by the customer.) 

Yes No N/A

17.2.5. Other means used to provide a visual or printed record of the total 

amount of money accepted by the device.

Yes No N/A

17.3. There is a brief period of time during which a bill has been accepted by the 

cash acceptor but has not yet been recognized by the device. The following 

criteria must be met to ensure that this information can be recalled in the 

event of a power failure.

Yes No N/A

17.3.1. Means provided to enable the attendant or customer to retrieve 

the bill (for example, a button which can be used during a power 

interruption to eject the bill or if the cash acceptor box can be 

removed by the attendant and the bill retrieved.) 

Yes No N/A

Note: There may be a space of time in which a bill can be caught partially in and 

out of the cash acceptor during a power interruption. In such a case, if the 

denomination of the bill is visible to the customer and attendant, this is sufficient 

to provide information about the bill being fed into the device at the time of the 

power interruption. The cash acceptor must comply with the other applicable 

items noted above.

It is expected that the retail motor fuel dispenser will comply with S.1.6.2. and 

the information on the product already dispensed can be recalled through this 

portion of the system.

17.4. Power should be interrupted at different points in the transaction to 

determine that all transaction information can be recalled in the event of a 

power interruption including combinations of the following:

17.4.1. After one bill has been inserted. Yes No N/A

17.4.2. After several bills have been inserted. Yes No N/A

17.4.3. While a bill is being inserted. Yes No N/A

17.4.4. After a bill has been inserted but not yet recognized. Yes No N/A

17.6.1.1. The identity (codes may be used) of the product 

purchased, the quantity purchased, the unit price, and 

the total price. 

Because the customer must be provided with the 

option of receiving a receipt, the system must not 

accept cash if sufficient paper is not available to 

complete the transaction.

Yes No N/A

17.6.1.2. Where a post-delivery discount(s) is applied, the sales 

receipt must provide:

 - the total quantity, unit price, and total computed 

price that were displayed on the dispenser at the 

end of the delivery prior to any post-delivery

Acknowledgements

The contents of this publication are the result of extensive meetings of the National Type Evaluation Program 

(NTEP) Technical Sectors and working groups assembled by National Conference on Weights and Measures 

(NCWM). The support, technical expertise, and judgment brought by members of industry and weights and measures 

officials have been critical to the development of the technical policy, checklists and test procedures. The 

contributions of all sector and work group members are greatly appreciated. The work to maintain these checklists 

continues.

We acknowledge and thank the technical advisor to the sectors from the National Institute of Standards and 

Technology, Office of Weights and Measures and the private sector, including Mr. Marc Buttler of the Measuring 

Sector and Mr. Doug Bliss of the Software Sector for their significant contributions. They have spent many hours 

before, during and after the sector meetings to prepare for, actively participate in and summarize the proceedings of 

these meetings.

We recognize the Measuring Sector Chair, Mr. Michael Keilty and Software Sector Co-Chairs Mr. Norman Ingram 

and 

Mr. James Pettinato in helping to organize and conduct the sector meetings in a fair and consensus-building manner. 

The recommendations forwarded from the sector to the NTEP Committee are the result of their guidance and 

leadership.

We also acknowledge the NTEP Committee for its careful assessment of the recommendations presented by the 

sector, commenting and revising when necessary, and approving the recommendations for inclusion in these 

checklists.

These contributions from so many people have resulted in a reference book that will help device manufacturers to 

design devices in compliance with NIST Handbook 44 and promote uniform procedures and assessment by type 

evaluation by the laboratories. This is a goal of NTEP.

National Type Evaluation Program

Electronic Cash Register Interfaced with Retail Motor Fuel Dispenser

Checklists and Test Procedures

Introduction

This checklist is intended for use when conducting general evaluations of new electronic cash registers (ECR) that are to 

interface with retail motor fuel dispensers. It is assumed that the dispenser was previously evaluated, if not, the Liquid 

Measuring Device checklist must be applied to the dispenser sale system. The ECR must interface with a d ispenser to 

perform this evaluation. Specific criteria that apply to service station control consoles are in the checklist for retail motor 

fuel dispensers and must be applied if the cash register also serves as the service station controller. As a minimum, two 

dispensers from different manufacturers, each of which includes all of the features to be listed on the ECR Certificate of 

Conformance (CC), must be evaluated with the ECR in order to have the statement "equivalent and compatible equipment" 

appear on the CC.

This checklist is designed in a logical sequence for the user to determine and record the conformance of the device with the 

elements of NIST Handbook 44. The user should make copies of the checklist to serve as worksheets and preserve the 

original for reference. In most cases, the results of evaluation for each element can be recorded by checking the appropriate

response. In some cases, the user is required to record values, results, or comments. In those cases, space is provided.

Identification

Code Reference: G-S.1. General

Each cash register must comply with the appropriate NIST Handbook 44 identification requirements. 

All equipment, except weights and separate parts necessary to the measurement process but not having any metrological 

effect, shall be clearly and permanently marked for the purposes of identification with the following information (prefix 

lettering may be initial capitals, all capitals, or all lower case.)

Location of the information: 

 

 

1.1. The name, initials, or trademark of the manufacturer or distributor. Yes No N/A

1.2. A model identifier that positively identifies the pattern or design of the device. The 

model identifier shall be prefaced by the word "Model," "Type," or "Pattern." These 

terms may be followed by the word "Number" or an abbreviation of that word. The 

abbreviation for the word "Number" shall, as a minimum, begin with the letter "N" 

(e.g., No or No.) The abbreviation for the word "Model" shall be "Mod" or "Mod." 

Prefix lettering may be initial capitals, all capitals, or all lower case.

Yes No N/A

1.3. Except for equipment with no moving or electronic component parts and not built for 

purpose, software-based devices, a non-repetitive serial number. The serial number 

shall be prefaced by the words "Serial Number" or an abbreviation, or a symbol, that 

clearly identifies the number as the required serial number. Abbreviations for the 

word "Serial" shall, as a minimum, begin with the letter "S," and abbreviations for the 

word "Number" shall, as a minimum, begin with the letter "N" (e.g., S/N, SN, Ser. 

No, and S No.)

Yes No N/A

1.4. For not built-for-purpose, software based devices the current software version 

designation. The version or revision identifier shall be prefaced by the word 

"Version" or "Revision" as appropriate and either word may be followed by the 

word "Number." The abbreviations for the word "Version" shall, as a minimum, 

Yes No N/A
NTEP Committee 2013 Final Report

Appendix D NTETC Measuring Sector Meeting Summary

Sub-appendix G – Publication 14 - ERC Interface with RMFD (Agenda Item 10)

NTEP - D / G12

begin with the letter "V." Abbreviations for the word "Revision" shall, as a 

minimum, begin with the letter "R." The abbreviations for the word "Number" 

shall, as a minimum, begin with the letter "N" (e.g., No or No.)

Code Reference: G-S.1. (e)

1.5. An NTEP Certificate of Conformance (CC) Number or a co rresponding CC 

addendum number for devices that have (or will have) a CC. The number shall be 

prefaced by the terms "NTEP CC," "CC," or "Approval." These terms may be 

followed by the word "Number" or an abbreviation for the word "Number." The 

abbreviation for the word "Number" shall as a minimum begin with the letter "N" 

(e.g., No or No.)

Yes No N/A

The device must have an area, either on the identification plate or on the device itself, 

suitable for the application of the Certificate of Conformance Number. If the area for 

the CC number is not part of an identification plate, then note its intended location 

below and how it will be applied.

1.5.1. Location of CC Number if not located with the identification information: 

 

1.6. The required information shall be so located that it is readily observable without the 

necessity of the disassembly of a part requiring the use of any means separate from 

the device.

Yes No N/A

1.7. The device must be marked with a unique serial number to identify the electronic 

element that controls the system. A remote display is not required to have a serial 

number because it usually does not have any electronics to analyze the signal 

received from the measuring element. Similarly, other elements of a system, (e.g., a 

printer, keyboard, cash drawer etc.) which cannot be operated as stand-alone units 

or are not intended to interface in a system of other models are not required to have 

a serial number.

Yes No N/A

1.8. The marking must be visible after installation. Yes No N/A

1.9. Equipment is to be marked on a surface that is an integral part of the chassis, which 

is visible after installation. If the required information is located on the back of the 

device, the same information must also appear on the side, front, or top. It may be 

installed on the housing only if the housing can be fitted with a security seal. The 

bottom of a device is not an acceptable surface.

Yes No N/A

1.10. The marking must be permanent. It may be a metal or plastic plate attached with 

pop rivets, adhesive, or other means. Removable bolts or screws are not permitted. 

A foil plate may be used provided it is destroyed in any attempt to remove it. 

Additionally, the printing on a foil plate must be easily read and not easily 

obliterated by rubbing with a relatively soft object (e.g., the wood of a pencil.)

Yes No N/A

Note: A location under a cover or inside a panel door is acceptable. Visibility may be 

achieved by placing a duplicate serial number badge on the front, side, or top of the ECR. 

This badge may contain only the serial number if the other information is visible elsewhere on 

the ECR.

Software-Based Devices

1.1. For not built-for-purpose, software-based devices, the following shall apply:

1.1.1. The required information in G-S.1 Identification. (a), (b), (d), and (e) shall 

be permanently marked or continuously displayed on the device. OR

Yes No N/A

1.1.2. The Certificate of Conformance (CC) Number shall be:

1.1.2.1. Permanently marked on the device. OR Yes No N/A

1.1.2.2. Continuously displayed. OR Yes No N/A

1.1.2.3. Accessible through an easily recognized menu and, if necessary, a 

submenu. Examples of menu and submenu identification include, 

but are not limited to "Help," "System Identification," "G S.1. 

Identification," or "Weights and Measures Identification."

Yes No N/A

Note: For (1.11.2.), clear instructions for accessing the information required in G-S.1. (a), 

(b), and (d) shall be listed on the CC, including information necessary to identify that the 

software in the device is the same type that was evaluated.

Indicating and Recording Elements

Code Reference: G-S.5.1. Price Look-up Codes (PLUs)

2.1. PLUs must operate only with appropriate information, (e.g., if a P LU activates a 

dispenser transaction, a volume input is required before a p rice is computed and 

recorded.) 

Yes No N/A

2.2. Other PLUs must not interact with dispenser information. Yes No N/A

2.3. Manual volume entries are permitted. They must be clearly identified on the receipt as 

a manual entry by the terms "Manual Fuel Sale." 

Yes No N/A

Note: All uppercase or a combination of upper and lower case letters are permitted provided 

the evaluating laboratory finds the resulting text to be clear and legible.

2.4. Incorrect entries shall be signaled by an audio and/or visual signal. Yes No N/A

2.5. A dispenser verification display (e.g., segment test) shall not be recorded by the ECR. Yes No N/A

Code Reference: S.1.6.2. Provision for Power Loss

2.6. Power Interruptions. First test with a power failure to the ECR alone. Then a power 

failure to the dispenser alone. Finally, a p ower failure to both components 

simultaneously. When power interruption occurs, the register must do one of the 

following:

2.6.1. Continue to function and perform correctly either automatically or manually. Yes No N/A

2.6.2. The transaction is halted and can be continued when power returns. Yes No N/A

Note: The ECR may continue to function while power is interrupted, (e.g., the ECR is 

equipped with an uninterruptible power supply.) Alternatively, the ECR may cease operation 

when power is interrupted and may resume the transaction in process at the time of the power 

failure when power is returned. Either alternative is acceptable provided that the ECR 

continues to function and perform correctly. There are no requirements to indicate when a 

power failure or interruption has occurred.

NTEP - D / G14

2.7. Provisions for Power Loss.

Note: For remote controllers, (e.g., cash register, console, etc.) which have the capability to 

retain information pertaining to a transaction, (e.g., stacked completed sales, if the 

information cannot be recalled at the dispenser following a power outage, (e.g., 

uninterruptible power supply or other means) then provisions must be made for the 

transaction information to be recalled and verified for at least 15 minutes following a power 

outage.

2.7.1. Remote controllers which stack completed sales must have a means to 

enable the transaction information to be recalled and verified for at least 15 

minutes.

Yes No N/A

Note: The criteria for power loss to a fuel dispenser are given in the retail motor fuel 

dispenser checklist.

2.8. An ECR shall be able to record all quantities, unit prices, and total prices up to the 

capacity of the dispenser. When the capacity of the quantity or total price is exceeded 

and the display "rolls over," the ECR shall not record the "rolled over" value but shall 

either record the correct total volume and total price or give an error indication.

Yes No N/A

2.9. A cash register shall not print the values from a dispenser until the delivery has been 

completed and dispenser turned off.

Yes No N/A

Items not measured or weighed may be split-priced according to general marketing 

practices. Acceptable price extensions will depend on individual State policies. 

Normally, the single item price will be the multiple item price divided by the number 

of items and rounded up to the next high cent. If the single item price is different from 

the price that would be computed as described, the price per item must be posted at the 

display. See FPLA value comparison considerations and the Model Unit Pricing 

Regulation. Suggested multiple item prices for test procedures are 3/$1.00 and 7/$1.00. 

The single item prices may be recorded as $.34, $.34, $.32 or $.34, $.33, $.33 and $.15,

$.15, $.15, $.15., $.15, $.15, $.10 or $.15, $.14, $.14, $.15, $.14, $.14, $.14, 

respectively.

2.10. Price calculations for multiple-item-priced commodities shall be correctly computed as 

described above for:

2.10.1. Prices entered via PLUs. Yes No N/A

2.10.1. Prices entered through the keyboard. Yes No N/A

3. Recorded Representations

Code Reference: G-S.5.1., S.1.6.7., and S.1.6.8. 

A sales receipt showing the quantity, unit price, total price, and product identity for each fuel delivery in a transaction is 

required for point-of-sale systems. A printed receipt must always be available to the customer upon request. In addition, 

systems may be equipped with the capability to issue an electronic receipt. T he customer may be given the option to 

receive the receipt electronically (e.g., via cell phone, computer, etc.).

Various forms (or representations) of sales receipt formats are acceptable provided they are clear and understandable. 

Guidelines are provided to assist manufacturers and weights and measures officials in determining the acceptability of 

formats. Symbols other than those given below may be acceptable, but they will be reviewed on a case-by-case basis. More 

descriptive symbols and terms are acceptable.

3.1. The unit of measure shall be clearly defined. Acceptable symbols for units are: Gallon 

Gal, of G for gallons and Liter, l or L for liters. Upper or lower case is optional except 

that a lower case "l" must not resemble a "1" (numeral one), (e.g. a script "l" is an 

acceptable symbol for liters.)

Yes No N/A

The unit of measure may be defined with either the quantity value, (e.g., 10 000 GAL) 

or with the unit price, (e.g., $1.119/Gal), not necessarily both.

Appendix D NTETC Measuring Sector Meeting Summary

Sub-appendix G – Publication 14 - ERC Interface with RMFD (Agenda Item 10)

NTEP - D / G15

3.2. Acceptable designations of the unit price are: "@" as a prefix to the unit price value, an 

upper or lower case "X" or slash between the quantity and unit price, $/G, PPG (price 

per gallon), PPL (price per liter), UP (unit price), P/G, price/Vol, PPU (price per unit), 

DOL/GAL.

Yes No N/A

3.3. The total fuel price must be clearly distinguished from other information in the fuel 

transaction. To identify the total fuel sale price, use one of the following methods:

3.3.1. Decimal point in the proper dollar position, (e.g., XX.XX.) If a dollar sign is 

not used, there must be at least one offset column of the least significant digit 

in recorded information, other than the sale price.

Yes No N/A

3.3.2. The words gas, diesel, or other product designation may be used with the word 

"SALE" (e.g., "FUEL SALE" or "GAS SALE") or the product identification 

followed by the sale price, (e.g., GAS 20.00.)

Yes No N/A

3.4. Each fuel delivery in a transaction for a single customer must be recorded separately. Yes No N/A

3.5. Where a p ost-delivery discount(s) is applied, the sales receipt must provide:

 - the total quantity, unit price, and total computed price that were displayed on the 

dispenser at the end of the delivery prior to any post-delivery discount(s);

 - an itemization of the post-delivery discounts to the unit price; and

 - the final total price of each fuel sale after all post-delivery discounts are applied.

See LMD Code S.1.6.8.

Yes No N/A

3.6. When a service station cash register/console is capable of recording sales transactions 

of other products, the fuel transaction must be clearly distinguished from the other 

transactions. A "product class" must be associated with the fuel transaction as well as 

the other transactions. In terms of format, the fuel transactions may be separated 

(blocked-off) from other transactions by blank lines or by at least one offset column 

between the sales price and the other recorded information.

Yes No N/A

3.7. The product identity for fuel need only distinguish it from other items. The product 

name, code number (similar to a p rice look-up code), or hose or pump number are 

acceptable designations of product identify. See LMD Code S.1.6.4.

Yes No N/A

Example 1 Example 2

Meat 3.89 Meat 3.89

Soda 2.99 Soda 2.99

Gas 5.080 G @ 1.000 5.08 Gas 4.080 G @ 1.000 4.08

Cig 1.00

Note: NIST Handbook 44 does not require that product identification, date, and change due 

be printed on a ticket or a cash register receipt. These requirements apply to recorded 

representations resulting from a final sale, not to deposit slips for prepay transactions, etc.

3.8. The quantity representation of an item sold by count must be expressed in whole units. 

An expression of count with a decimal point and trailing zeroes, (e.g., 2.00 items) is 

acceptable provided that fractions of a whole unit cannot be expressed.

Yes No N/A

4. Provisions for Sealing 

Code Reference: G-S.8. Provision for Sealing Electronic Adjustable Components

Remote controllers, which have the capabilities to electronically adjust components that affect the performance of a device, 

shall have provisions for approved means of security. See LMD - Appendix A - Philosophy for Sealing, Typical Features to 

be Sealed.

National Type Evaluation Technical Committee (NTETC) 

Software Sector Meeting Summary

March 20-21, 2012

Columbus, Ohio

INTRODUCTION

The charge of the NTETC Software Sector is important in providing appropriate type evaluation criteria for 

software-based weighing or measuring device based on specifications, tolerances and technical requirements of 

NIST Handbook 44, Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring 

Devices, Section 1.10. General Code, Section 2 f or weighing devices, Section 3 for liquid and vapor measuring 

devices, and Section 5 for taximeters, grain analyzers, and multiple dimension measuring devices. The Sector’s 

recommendations are presented to the National Type Evaluation Program (NTEP) Committee each January for 

approval and inclusion in NCWM Publication 14, Technical Policy, Checklists, and Test Procedures, for national 

type evaluation.

The Sector is also called upon occasionally for technical expertise in addressing difficult NIST Handbook 44 issues 

on the agenda of the National Conference on Weights and Measures (NCWM) Specifications and Tolerances (S&T) 

Committee. S ector membership includes industry, NTEP laboratory representatives, technical advisors and the 

NTEP Administrator. Meetings are held annually, or as needed and are open to all NCWM members and other 

registered parties.

Suggested revisions are shown in bold face print by striking out information to be deleted and underlining

information to be added. Requirements that are proposed to be nonretroactive are printed in bold faced italics. 

Note: It is the policy of the National Institute of Standards and Technology (NIST) to use metric units of measurement in 

all of its publications; however, recommendations received by NCWM technical committees and regional weights and 

measures associations have been printed in this publication as submitted. Therefore, the report may contain references in 

inch-pound units.

STATUS REPORTS

1. 2012 NCWM Interim Meeting Report 

Source:

NCWM S&T Committee Agenda

Background/Discussion:

There was one item on the NCWM S&T Committee Agenda for the 2012 NCWM Interim Meeting related to work 

done by the NTETC Software Sector. Publication 15 (2012), S&T Item 360-2 relates to the 2012 NTETC Software 

Sector Agenda Item 1: Marking Requirements. 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E3 

Conclusion:

Attendees indicated that the 2012 Interim Meeting was well attended. Most issues were not S&T issues – more laws 

and packaging type issues. The one issue that was on the S&T Committee Agenda has been changed from 

Informational to Developing. Mr. Truex, NTEP Administrator, was not at the Open Hearings when that item was 

discussed, but Mr. Lewis, Rice Lake Weighing Systems, Inc. was. He said it didn’t go anywhere.

2. 2012 International Activity Report 

Source:

NTETC Software Sector

Background/Discussion:

Dr. Thompson, National Institute of Standards and Technology (NIST), Office of Weights and Measures (OWM), 

will provide a synopsis of international activity that relates to the work of the Sector. Mr. Pettinato, Chair, will 

summarize the discussion that took place at the European Cooperation in Legal Metrology (WELMEC) WG 7 

meeting in December 2011.

Conclusion:

Highlights of interest to the NTETC Software Sector:

• Workshop on Operating Systems in Legal Metrology hosted by Physikalisch-Technische Bundesanstalt 

(PTB) December 2011 coincident with WELMEC WG7 meeting.

• New D-11 draft circulated for comment early 2012.

Mr. Pettinato, Chair attended the WELMEC WG7 meeting in Berlin in December. He was struck by how similar 

the discussion was to our NCWM meetings. We are trailing in requirements for software security. They are trying 

to enforce authentication, identification, self-checking, etc. They’re dealing with Linux and other open-source 

issues. Some approvals have taken 18 months. They seem to be starting in a new direction, possibly rewriting D 7.2 

to reference software documents for IT standards for security. This would result in them only focusing on 

metrological issues in the software, leaving the other standards to cover the remaining issues in security. Currently 

PTB references a National Security Agency document on securing Red Hat Linux.

Mr. Beattie, Measurement Canada, asked about the feeling regarding Common Criteria. Mr. Pettinato reported that 

there were a couple presentations on this subject. There are big concerns about data privacy. PTB has backed off 

from this approach since they’ve realized that it puts a lot of responsibility on their plate. This is part of why they 

are looking to recommend various IT standards. Dr. Thompson reported that the Germans had wanted to go to the 

extreme of detailed code-walking. Mr. Oldham, Gilbarco, Inc., mentioned that though Europe has apparently 

backed off on this, India and Mexico appear to be continuing to pursue it.

CARRY-OVER ITEMS

3. Software Identification/Markings 

Source: 

NTETC Software Sector

Background/Discussion:

Since its inception, the Sector has wrestled with the issue of software identification and marking requirements. See 

the 2011 Software Sector Meeting Summary and the 2012 Interim Meeting S&T Agenda Item 360-2 for more 

background on this item. 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E4 

NIST, OWM had been adding items to the S&T Agendas that confused matters since the perception was that this 

Sector had contributed to this input. Most of the confusion arose in the 1990s, due to some items being approved, 

and others, such as the definitions for “Built-for-Purpose” and “Not Built-for-Purpose,” not being approved. 

Mr. Truex, NTEP Administrator, discussed the difficulty there has been in coming to a consensus on these issues 

with a representative of the NTEP Committee. Suggestions from NTEP to come to some resolution has been to 

write an article for the newsletter (which Mr. Bliss, Mettler-Toledo, LLC, had already done, to no effect), sending a 

questionnaire to the NTEP community, asking what they’d like to see, and sending a representative from this Sector 

to the S&T Committee.

Mr. Roach, California Division of Measurement Standards, is concerned that some people may want to interpret 

G-S.1.(c) as requiring a serial number for software. Mr. Lewis, Rice Lake Weighing Systems, Inc. pointed out that 

the computer that the software was running on could have the serial number, not the software itself. That shouldn’t 

matter, regardless. 

Mr. Bliss, Mettler-Toledo, LLC, pointed out that the terminology in G-S.1. “All equipment”, could be interpreted to 

mean that it doesn’t apply to software. It was proposed that G-S.1.(c) be amended to add “and software”. Mr. Bliss 

suggested submitting a document explaining the reasoning behind the proposed changes, rather than assume that the 

text is self-explanatory. Making a p resentation to the various Committees on the subject in addition would be 

beneficial as well. If a document is written, perhaps the examples given in G-S.1.d.3.(a) can be eliminated. 

“Metrologically significant” isn’t explicitly defined, but it’s been used since time immemorial.

Attempts to modify G-S.1.1. have been controversial, both in this meeting and in other Committees. Unfortunately, 

there has been little constructive feedback from the other Committees. It would probably be easier to incorporate 

specific examples given in G-S.1.1.b.3 in NCWM Publication 14. After some discussion, the previously proposed 

language was modified slightly to address some of the concerns received via feedback from other Sectors and 

interested parties:

NIST Handbook 44 – Proposed changes:

G-S.1. Identification. – All equipment, except weights and separate parts necessary to the measurement process but not 

having any metrological effect, shall be clearly and permanently marked for the purposes of identification with the following 

information: 

(a) the name, initials, or trademark of the manufacturer or distributor; 

(b) a model identifier that positively identifies the pattern or design of the device; 

(1) The model identifier shall be prefaced by the word “Model,” “Type,” or “Pattern.” These terms may be 

followed by the word “Number” or an abbreviation of that word. The abbreviation for the word “Number” 

shall, as a minimum, begin with the letter “N” (e.g., No or No.). The abbreviation for the word “Model” 

shall be “Mod” or “Mod.” Prefix lettering may be initial capitals, all capitals, or all lowercase. 

[Nonretroactive as of January 1, 2003] 

(Added 2000) (Amended 2001) 

(c) a nonrepetitive serial number, except for equipment with no moving or electronic component parts and not-builtfor-purpose software-based software devices software;

[Nonretroactive as of January 1, 1968] 

(Amended 2003 and 20XX) 

(1) The serial number shall be prefaced by words, an abbreviation, or a symbol, that clearly identifies the 

number as the required serial number. 

[Nonretroactive as of January 1, 1986] 

(2) Abbreviations for the word “Serial” shall, as a minimum, begin with the letter “S,” and abbreviations for the 

word “Number” shall, as a minimum, begin with the letter “N” (e.g., S/N, SN, Ser. No., and S. No.). 

[Nonretroactive as of January 1, 2001] 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E5 

(d) the current software version or revision identifier for not-built-for-purpose software-based electronic devices; 

[Nonretroactive as of January 1, 2004] 

(Added 2003) (Amended 20XX)

(1) The version or revision identifier shall be prefaced by words, an abbreviation, or a symbol, that clearly 

identifies the number as the required version or revision. 

[Nonretroactive as of January 1, 2007] 

(Added 2006) 

(2) Abbreviations for the word “Version” shall, as a minimum, begin with the letter “V” and may be followed by 

the word “Number.” Abbreviations for the word “Revision” shall, as a minimum, begin with the letter “R” 

and may be followed by the word “Number.” The abbreviation for the word “Number” shall, as a minimum, 

begin with the letter “N” (e.g., No or No.). 

[Nonretroactive as of January 1, 2007] 

(Added 2006) 

(3) The version or revision identifier shall be accessible via the display. Instructions for displaying the version 

or revision identifier shall be described in the CC. As an exception, permanently marking the version or 

revision identifier shall be acceptable under the following conditions:

(a) The user interface does not have any control capability to activate the indication of the version or 

revision identifier on the display, or the display does not technically allow the version or revision 

identifier to be shown (analog indicating device or electromechanical counter) or

(b) the device does not have an interface to communicate the version or revision identifier. 

(e) an NTEP CC number or a corresponding CC Addendum Number for devices that have a CC. 

(1) The CC Number or a corresponding CC Addendum Number shall be prefaced by the terms “NTEP CC,” 

“CC,” or “Approval.” These terms may be followed by the word “Number” or an abbreviation of that word. 

The abbreviation for the word “Number” shall, as a minimum, begin with the letter “N” (e.g., No or No.) 

[Nonretroactive as of January 1, 2003] 

The required information shall be so located that it is readily observable without the necessity of the disassembly of a part

requiring the use of any means separate from the device. 

(Amended 1985, 1991, 1999, 2000, 2001, 2003, and, 2006 and 201X) 

G-S.1.1. Location of Marking Information for Not-Built-For-Purpose all Software-Based Devices. – For not-built-forpurpose, software-based devices, either: 

(a) The required information in G-S.1. Identification. (a), (b), (d), and (e) shall be permanently marked or 

continuously displayed on the device; or 

(b) The Certificate of Conformance Number shall be: 

(1) permanently marked on the device; 

(2) continuously displayed; or 

(3) accessible through an easily recognized menu and, if necessary, a submenu. Examples of menu and submenu 

identification include, but are not limited to, “Help,” “System Identification,” “G-S.1. Identification,” or 

“Weights and Measures Identification.” 

Note: For (b), clear instructions for accessing the information required in G-S.1. (a), (b), and (d) shall be listed on the CC, including 

information necessary to identify that the software in the device is the same type that was evaluated.

(Added 2003) (Amended 2006 and 20XX) 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E6 

The new language in G-S.1.1. reflects that the Sector reached consensus on the following positions:

• The software version/revision should (with very few exceptions – see D-31 5.1.1) be accessible via the user 

interface.

• The means by which the software version is accessed must be described in the Certificate of Conformance 

(CC). 

In addition, it was asserted that the previously recommended changes to G-S.1.1.(b)(3) in fact are not really 

necessary; the current language of NIST Handbook 44 empowers the laboratories to enforce “easily recognizable” as 

they see fit. I n fact, the previously generated “list” of icons and menu options could certainly be used by the 

examining laboratories as part of the approval process (e.g., in NCWM Publication 14). Of course, a manufacturer 

who is reviewing NIST Handbook 44 so as to develop an acceptable device may benefit from more explicit 

guidance. Where does such guidance belong? 

Comments related to the circulated list included a co mment from the Scale Manufacturers Association (SMA) 

suggesting that a definition is needed for “software-based devices.” SMA opposed the definitions previously put 

forth by the Sector. I t was suggested that perhaps SMA would be more amenable to a d efinition that doesn’t 

differentiate between software types. 

The conclusion from the 2011 NTETC Software Sector Meeting was that the Sector will request feedback on the 

new recommended language for G-S.1. and G-S.1.1. since it does deviate somewhat from previous submissions. It 

is hoped that the various interested Sectors, regions, and associations will give this new proposal careful thought and 

submit their concerns to the NTETC Software Sector.

The list of suggested icons/menus that should be considered finite options for manufacturers was updated to reflect 

comments received by the Sector. The Sector now believes this approach is adequate without a change to NIST 

Handbook 44; the NTEP laboratories would be able to enforce “easily recognizable” against this finite list. Hence, 

the Sector recommends the list be inserted into NCWM Publication 14. 

Crafting a definition for “software based device” may be included as an item in a future agenda. Note the term “not 

built for purpose, software based device” is already used in NIST Handbook 44. 

Some concerns seemed to stem from a lack of understanding of intent. It was suggested that a supplementary 

document could be written, explaining the intent of the “software based device” terminology.

Conclusion: 

The Sector wishes to continue promotion of this item, with the minor edits shown above included addressing some 

of the concerns of other interested parties. Since this is currently defined as a Developing Item, it cannot be moved 

to a Voting Item at the 2012 NCWM Annual Meeting; it will have to wait until 2013. In January of 2013, the 

decision will be made as to changing the status of this item. This Sector will need to push to accomplish 

this. Developing a presentation and/or writing a supplementary document that would explain the intent behind the 

proposed changes to G-S.1. and G-S1.1. would most likely help in getting these changes passed. The annual 

meeting would be an appropriate venue for a presentation, though it may be too late to get it onto the agenda. The 

SMA is having their meeting next month in Monterey, California. Mr. Fink, ITW Food Equipment/Hobart, may be 

available to assist Mr. Pettinato, Chair, in putting together a presentation and volunteered to present it at the SMA 

Meeting.

4. Identification of Certified Software

Source: 

NTETC Software Sector

Background/Discussion: 

This item originated as an attempt to answer the question, “How does the field inspector know that the software 

running in the device is the same software evaluated and approved by the lab?” In previous meetings it was shown 

that the international community has addressed this issue (both WELMEC and International Organization of Legal 

Metrology [OIML]). 

From WELMEC 7.2:

Required Documentation: 

The documentation shall list the software identifications and describe how the software identification is created, 

how it is inextricably linked to the software itself, how it may be accessed for viewing, and how it is structured 

in order to differentiate between version changes with and without requiring a type approval. 

From OIML D-31:

The executable file “tt100_12.exe” is protected against modification by a checksum. The value of checksum as 

determined by algorithm XYZ is 1A2B3C. 

Previous discussions have included a listing of some additional examples of possible valid methods (not limiting):

• Cyclical Redundancy Check (CRC)

• Checksum

• Inextricably Linked version no.

• Encryption

• Digital Signature

Is there some method to give the weights and measures inspector information that something has changed? 

Yes, the Category III Audit Trail or other means of sealing. 

How can the weights and measures inspector identify an NTEP certified version? 

They can’t, without adding additional requirements such as those described here, in conjunction with including the 

identifier on the CC.

The Sector has continued to believe that we should work towards language that would include a requirement similar 

to the OIML requirement in NIST Handbook 44. It is also the opinion of the Sector that a specific method should 

not be defined; rather the manufacturer should utilize a method and demonstrate the selected identification 

mechanism is suitable for the purpose. It is not clear from the discussion where such proposed language might 

belong.

Closely related to this concept of uniquely identifying software is the practice of software separation. The Sector 

sees the benefit in allowing that metrological software be separated from non-metrological software for ease of 

identification and evaluation.

From OIML:

Separation of software parts – All software modules (programs, subroutines, objects, etc.) that perform 

metrologically significant functions or that contain metrologically significant data domains form the 

metrologically significant software part of a measuring instrument (device or sub-assembly). The conformity 

requirement applies to all parts and parts shall be marked according to Section G-S-X.X.
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E8 

If the separation of the software is not possible or needed, then the software is metrologically significant as a 

whole.

(Segregation of parameters is currently allowed – see table of sealable parameters)

Previously recommended text intended to be added to NCWM Publication 14 was discussed and modified slightly: 

Identification of Certified Software:

Note: Manufacturers may choose to separate metrologically significant software from non-metrologically 

significant software. Separation would allow the revision of the non-metrological portion without the need for 

further evaluation. In addition, non-metrologically significant software may be updated on devices without 

breaking a s eal, if so designed. Separation of software requires that all software modules (programs, 

subroutines, objects, etc.) that perform metrologically significant functions or that contain metrologically 

significant data domains form the metrologically significant software part of a measuring instrument (device or 

sub-assembly). If the separation of the software is not possible or needed, then the software is metrologically 

significant as a whole. The conformity requirement applies to all parts and parts shall be marked 

according to Section G-S-X.X.

The manufacturer must describe and possibly demonstrate how the version or revision identifier is directly and 

inseparably linked to the metrologically significant software. Where the version revision identifier is comprised 

of more than one part, the manufacturer shall describe which portion represents the metrological significant 

software and which does not.

From OIML D-31:

Legally relevant software of a measuring instrument/electronic device/sub-assembly shall be clearly identified 

with the software version or another token. The identification may consist of more than one part but at least one 

part shall be dedicated to the legal purpose.

The identification shall be inextricably linked to the software itself and shall be presented or printed on 

command or displayed during operation or at start up for a measuring instrument that can be turned off and on 

again. If a sub-assembly/an electronic device has neither display nor printer, the identification shall be sent via 

a communication interface in order to be displayed/printed on another sub-assembly/electronic device.

The first sentence of the first paragraph above is already addressed in NIST Handbook 44’s marking requirements.

In 2010, the Sector recommended the following change to NIST Handbook 44, General Code, G-S.1.(d) to add a 

new subsection (3):

(d) the current software version or revision identifier for not-built-for-purpose software-based electronic

devices; 

[Nonretroactive as of January 1, 2004]

(Added 2003) (Amended 20XX) 

(1) The version or revision identifier shall be prefaced by words, an abbreviation, or a symbol, that 

clearly identifies the number as the required version or revision. 

[Nonretroactive as of January 1, 2007] 

(Added 2006)

(2) Abbreviations for the word “Version” shall, as a minimum, begin with the letter “V” and may be 

followed by the word “Number.” Abbreviations for the word “Revision” shall, as a minimum, begin 

with the letter “R” and may be followed by the word “Number.” The abbreviation for the word 

“Number” shall, as a minimum, begin with the letter “N” (e.g., No or No.). 

[Nonretroactive as of January 1, 2007] 

(Added 2006)
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E9 

(3) The version or revision identifier shall be directly and inseparably linked to the software itself. The 

version or revision identifier may consist of more than one part, but at least one part shall be 

dedicated to the metrologically significant software.

[Nonretroactive as of January 1, 201X] 

(Added 20XX)

Also the Sector recommends the following information be added to NCWM Publication 14 as 

explanation/examples:

• Unique identifier must be displayable/printable on command or during operation, etc. 

• At a minimum, a version/revision indication (1.02.09, rev 3.0 a, etc). Could also consist of/contain 

checksum, etc (crc32, for example)

There was some additional discussion on this item regarding where this new requirement was best located. It was 

suggested that the first sentence of G-S.1.d.(3) could be added as a clause to the base paragraph G-S.1(d) text, e.g. 

“the current software version or revision identifier for not-built-for-purpose software-based devices, which 

shall be directly and inseparably linked to the software itself;” .

It also was suggested that the second sentence in G-S.1.d. (3) might be more suitable for NCWM Publication 14, as 

it describes more “how” than “what” the requirement entails.

In addition, the Sector considered the following information to be added to NCWM Publication 14 as 

explanation/examples:

• The current software identifier must be displayable/printable on command during operation (or made 

evident by other means deemed acceptable by G-S.1.) 

• At a minimum, the software identifier must include a version/revision indication (1.02.09, rev 3.0 a, etc.). 

It could also consist of/contain checksum, etc. (crc32, for example).

• The version or revision identifier may consist of more than one part, but at least one part shall be dedicated 

to the metrologically significant software.

Other questions still outstanding are: 

• If we allow hard-marking of the software identifier (the Sector has wavered on this in the past), does the 

above wording then imply that some mechanical means is required (i.e. physical seal) to “inseparably link” 

the identifier to the software? If it’s acceptable to hard-mark the version or revision, the requirement to 

inseparably link it to the software is waived.

• If a device is capable of doing so, does it still have to be able to display, print or communicate the identifier 

somehow, even if it is hard-marked? If the device is capable of doing so, it must.

At the 2012 NTETC Software Sector Meeting, there was some discussion as to where the terminology regarding 

inextricably linking the software version or revision to the software itself belonged. At the moment, it is not 

incorporated in the proposed text for G-S.1. NCWM Publication 14 may be a better option for the time being. This 

would be another item that would benefit from further explanation in a supplementary document.

One suggestion was this revision to G-S.1.(d): 

(d) when metrologically significant software is employed, the current software version or revision identifier, 

which shall be directly and inseparably linked to the software itself;, for not-built-for-purpose softwarebased electronic devices; 

Alternatively, if the previously proposed new subsection G-S.1.(d)(3) from Item 1 is adopted, this concept could be 

inserted thus: 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E10

(3) The version or revision identifier shall be directly and inseparably linked to the software itself and

accessible via the display. Instructions for displaying the version or revision identifier shall be 

described in the CC. As an exception, permanently marking the version or revision identifier shall 

be acceptable under the following conditions:

Several sector members were of the opinion that attempting to make this change at the same time as the earlier 

changes might be a difficult sell. Mr. Truex, NTEP Administrator, reiterated the necessity of baby steps.

Conclusion:

The Sector recommends adding the following to NCWM Publication 14 and forward to NTETC Weighing, 

Measuring, and Grain Analyzer Sectors for feedback: 

Identification of Certified Software:

Note: Manufacturers may choose to separate metrologically significant software from non-metrologically 

significant software. Separation would allow the revision of the non-metrological portion without the need for 

further evaluation. In addition, non-metrologically significant software may be updated on devices without 

breaking a seal, if so designed. Separation of software requires that all software modules (programs, 

subroutines, objects etc.) that perform metrologically significant functions or that contain metrologically 

significant data domains form the metrologically significant software part of a measuring instrument (device or 

sub-assembly). If the separation of the software is not possible or needed, then the software is metrologically 

significant as a whole. The conformity requirement applies to all parts and parts shall be marked according to 

Section G-S-X.X.

The manufacturer must describe and possibly demonstrate how the version or revision identifier is directly and 

inseparably linked to the metrologically significant software. Where the version revision identifier is comprised 

of more than one part, the manufacturer shall describe which portion represents the metrological significant 

software and which does not.

Also, it was decided to forward the two alternate options for adding requirements for uniquely identifying software 

to the individual Sectors: 

One suggestion was this revision to G-S.1.d:

(d) when metrologically significant software is employed, the current software version or revision identifier, 

which shall be directly and inseparably linked to the software itself;, for not-built-for-purpose softwarebased electronic devices; 

Alternatively, if the previously proposed new subsection G-S.1.(d)(3) from Item 1 is adopted, this concept could be 

inserted thus: 

(3) The version or revision identifier shall be directly and inseparably linked to the software itself and

accessible via the display. Instructions for displaying the version or revision identifier shall be 

described in the CC. As an exception, permanently marking the version or revision identifier shall be 

acceptable under the following conditions:

Both alternatives will be sent to the Sectors for feedback.

5. Software Protection/Security

Source: 

NTETC Software Sector

Background/Discussion:

The Sector agreed that NIST Handbook 44 already has audit trail and physical seal, but these may need to be 

enhanced.

From the WELMEC Document:

Protection against accidental or unintentional changes

Metrologically significant software and measurement data shall be protected against accidental or unintentional 

changes.

Specifying Notes:

Possible reasons for accidental changes and faults are: unpredictable physical influences, effects caused by user 

functions and residual defects of the software even though state of the art of development techniques have been 

applied. 

This requirement includes consideration of:

a) Physical influences: Stored measurement data shall be protected against corruption or deletion when a 

fault occurs or, alternatively, the fault shall be detectable.

b) User functions: Confirmation shall be demanded before deleting or changing data.

c) Software defects: Appropriate measures shall be taken to protect data from unintentional changes that 

could occur through incorrect program design or programming errors, for example, plausibility checks.

Required Documentation:

The documentation should show the measures that have been taken to protect the software and data against 

unintentional changes.

Example of an Acceptable Solution:

• The accidental modification of software and measurement data may be checked by calculating a 

checksum over the relevant parts, comparing it with the nominal value and stopping if anything has 

been modified.

• Measurement data are not deleted without prior authorization, for example, a dialogue statement or 

window asking for confirmation of deletion.

• For fault detection see also Extension I.

The Sector continued to develop a proposed checklist for NCWM Publication 14. The numbering will still need to 

be added. This is based roughly on R 76 – two checklist and discussions beginning as early as the October 2007 

NTETC Software Sector Meeting. The information requested by this checklist is currently voluntary, however, it is 

recommended that applicants comply with these requests or provide specific information as to why they may not be 

able to comply. Based on this information, the checklist may be amended to better fit with NTEP’s need for 

information and the applicant’s ability to comply. 

The California, Maryland and Ohio laboratories agreed to use this check list on one of the next devices they have in 

the laboratory and report back to the Sector on what the problems may be. In February 2011, the North Carolina 

laboratory was also given a copy of the check list to try.

4. Operating System and / or Program(s) Accessible for the User

4.1. Check whether a checksum or equivalent signature is generated over the 

machine code of the metrologically significant software (program 

module(s) subject to legal control Weights and Measures jurisdiction and 

type-specific parameters). Is there a means to determine that the 

software is complete and authorized by the vendor – not damaged or 

someone else’s program?

Yes No N/A

4.2. Check whether the metrologically significant software will detect and act 

upon any unauthorized alteration of the metrologically significant 

software using simple software tools (e.g., text editor). If the software is 

altered, is there some means to determine whether that has occurred? 

As an example, can an average text editor cause damage?

Yes No N/A

5. Software Interface(s)

5.1. This is intended to determine whether the manufacturer has at least considered these 

issues. Verify the manufacturer has documented:

5.1.1. The program modules of the metrologically significant software 

are defined and separated. Has the metrologically significant 

software been separated from the other software?

metrologically significant software. This is something that’s 

used to close access to the metrologically significant 

software.

5.1.3. The functions of the metrologically significant software that can 

be accessed via the protective software interface. This could be 

all, none, or some. Functions mean more than just changing 

parameters. As an example, this may mean whether you can 

take a tare or not.

Yes No N/A

5.1.4. The parameters that may be exchanged via the protective 

software interface are defined. The sealed parameter list from 

Pub. 14.

Yes No N/A

(external) application programmer. If so, how is the 

metrologically-significant data and functionality protected? 

What can it do? Is it fixed? Can it be expanded?

Yes No N/A

The Maryland laboratory had particular questions regarding 3.1. and 5.1. The information for 3.1. could be acquired 

from an operator’s manual, a training video, or in-person training. The items in 5.1. were confusing to the 

evaluators. The terminology is familiar to software developers, but not necessarily others. It was indicated that 

manufacturers were typically quick to return the filled out questionnaire, but he didn’t know how his laboratory was 

supposed to verify that it was true. Generally, the laboratories wouldn’t be expected to verify things to that level. 

For example, if the manufacturer states that a checksum is used to ensure integrity, the laboratories wouldn’t be 

expected to evaluate the algorithm used.

The intent was to see whether the manufacturer had at least considered these issues, not for evaluators to become 

software engineers. Perhaps a glossary or descriptive paragraphs might be added to assist the evaluators for if the 

manufacturer has questions for the evaluators.
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E14

OIML makes use of supplementary documents to explain the checklist they use. Below are links:

• http://www.oiml.org/publications/D/D031-e08.pdf

• http://www.welmec.org/latest/guides/72.html

• http://www.welmec.org/fileadmin/user_files/publications/2-3.pdf

WELMEC document 2.3 is the original source for our checklist, but it’s been significantly revised and simplified. 

Mr. Payne, Maryland Department of Agriculture, is going to review the other documents and come up with some 

suggestions for the checklist. Mr. Roach, California Division of Measurement Standards, is going to begin using the 

checklist. The international viewpoint is that any device running an operating system is considered to be Type U. 

Mr. Roach mentioned that they’re having lots of problems with “skimmers” stealing PIN’s. Is there some way they 

can detect this?

Mr. Lewis, Rice Lake Weighing Systems, Inc., mentioned that he liked Measurement Canada’s website. When 

answering similar questions, different pages would appear, based on answers to those 

questions: http://www.ic.gc.ca/eic/site/mc-mc.nsf/eng/lm00573.html 

At the 2011 NTETC Software Sector Meeting, the laboratories were polled to obtain any feedback on the use of the 

checklist. Maryland attempted to use this checklist a few times. They had some difficulty obtaining answers from 

the manufacturers because the individual(s) interacting with the Maryland evaluator didn’t always have the required 

information on hand. More experience in using the checklist will help determine what needs to be revised.

It was suggested that the checklist could be sent to manufacturers for their feedback as well, with the stipulation that 

it is a completely voluntary exercise and purely informational at this point. The laboratories will coordinate with 

willing manufacturers to obtain feedback.

Conclusion: 

Work is ongoing on this item with the intent that it eventually will be incorporated as a ch ecklist in NCWM 

Publication 14; again the laboratories are requested to try utilizing this checklist for any evaluations on softwarebased electronic devices.

The checklist has been reviewed with an eye to making its terminology clearer to laboratories. Some examples and 

clarifications have been added as shown in the discussion section of this item. The revised checklist will be 

distributed to the laboratories for additional review. Maryland and California laboratories agreed to use the checklist 

on a trial basis.

6. Software Maintenance and Reconfiguration

Source: 

NTETC Software Sector

Background/Discussion:

After the software is completed, what do the manufacturers use to secure their software? The following items were 

reviewed by the Sector. 

1. Verify that the update process is documented.

2. For updates to be automatically verified by the device, installed software must be authenticated and 

checked for integrity.

Technical means shall be employed to guarantee the authenticity of the loaded software (i.e., that it 

originates from the owner of the type approval certificate). This can be accomplished (e.g., by 

cryptographic means such as signing). The signature is checked during loading. If the loaded software 

fails this test, the instrument shall discard it and either use the previous version of the software or become 

inoperative. 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E15

Technical means shall be employed to guarantee the integrity of the loaded software (i.e., that it has not been 

inadmissibly changed before loading). This can be accomplished for example, by adding a checksum or hash 

code of the loaded software and verifying it during the loading procedure. If the loaded software fails this test, 

the instrument shall discard it and either use the previous version of the software or become inoperative. 

3. Verify that the sealing requirements are met

This item is only addressing the software update, it can be either verified or traced. 

4. Verify that if the upgrade process fails, the device is inoperable or the original software is restored. 

The question before the group is can this be made mandatory, in other words. 

“The manufacturer shall ensure by appropriate technical means (e.g., an audit trail) that traced updates of 

metrologically significant software are adequately traceable within the instrument for subsequent 

verification and surveillance or inspection. This requirement enables inspection authorities, which are 

responsible for the metrological surveillance of legally controlled instruments, to back-trace traced updates 

of metrologically significant software over an adequate period of time (that depends on national 

legislation).” 

The Sector discussed how to best move this item forward, and there was also some discussion as to whether new 

language for the General Code was required. The general consensus of the group after considering feedback from 

external interested parties is that a new G-S.9. with explicit requirements is not necessary (nor likely to be adopted 

by NCWM) and that this requirement belongs in the NCWM Publication 14 lists of sealable parameters rather than 

in NIST Handbook 44.

Additional work done at the 2011 NTETC Software Sector Meeting to further develop the proposed text toward 

inclusion in NCWM Publication 14 resulted in the following:

The updating of metrologically significant software shall be considered a sealable event. The software 

that checks for authenticity and integrity for a Traced Update, as well as the software responsible for 

generating and viewing the audit trail, is metrologically significant.

Verified Update

A verified update is the process of installing new software where the security is broken and the device must be 

re-verified. Checking for authenticity and integrity is the responsibility of the owner/user.

Traced Update

A traced update is the process of installing new software where the software is automatically checked for 

authenticity and integrity, and the update is recorded in a software update log or Category 3 audit trail. The 

audit trail entry shall include the software identification of the newly installed version.

Note: It’s possible that the Philosophy of Sealing section of NCWM Publication 14 may already address the above 

IF the definitions of Verified and Traced Updates (and the statement below) were to be added. The contrary 

argument was that it may be better to be explicit:

Conclusion:

As a first step, attempt to add only the following to the Philosophy of Sealing in NCWM Publication 14: 

The updating of metrologically significant software, including software that checks the authenticity and 

integrity of the updates, shall be considered a sealable event.

Mr. Truex, NTEP Administrator, believes the above sentence is unnecessary since it’s self-evident. It was agreed to 

ask the Sectors for feedback on the value of this addition. 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E16

Though the Sector is currently recommending only the single sentence be incorporated into NCWM Publication 14

for the time being, ultimately, the Sector may wish to advance the remaining language of the original item 

submission. 

7. NTEP Application for Software and Software-based Devices

Source: 

NTETC Software Sector

Background/Discussion: 

The purpose of initiating this item was to identify issues, requirements and processes for type approving software 

applications. It was suggested that it may be useful to the laboratories to devise a separate submission form for 

software and devices. What gets submitted? What requirements and mechanisms for submission should be 

available? Validation in the laboratories - all required subsystems shall be included to be able to simulate the system 

as installed.

Mr. Roach, California Division of Measurement Standards, stated that if the software package being evaluated 

supports platforms/subsystems from multiple manufacturers, testing should be done using at least two 

platforms/subsystems. Scale laboratories and scale manufacturers indicated that this is not usually done for scale 

evaluations.

Mr. Truex, NTEP Administrator, indicated that we can move in this direction, but felt that it was somewhat 

premature to develop this thoroughly now. At the point where the Sector has developed checklist requirements, then 

we could move to perhaps add a s ubsection to current NTEP applications for applicable software. Refer to 

D-31.6.1. It was also agreed that there seems to be no reason for limiting the scope of this item to software-only 

applications, and hence all software/software-based devices could benefit from an enhanced application process. 

Hence the description of this agenda item was modified as shown in the marked up heading.

Comments given at the meeting indicate that current practice does not require anything different for 

software/software based devices compared to any other type approval. It was also noted that for international 

applications, OIML D-31.6.5 states, “The approval applicant is responsible for the provision of all the required 

equipment and components.” This would likely also be the policy of NTEP.

Mr. Truex, NTEP Administrator, clarified that the current applications have some checks of software already, not 

that they couldn’t benefit eventually from some additions. Once the checklist has been refined, it might prove 

useful. This won’t likely be a separate software checklist but rather some additional questions that will pertain to 

software, added to the existing list of questions that are currently asked.

Since the checklist is still being tried out by some of the laboratories, the Sector is not quite ready to develop this 

fully. Some documentation that eventually might be required by applicants could include (from WELMEC doc. 7-2 

Issue 4):

• A description of the software functions that are metrologically significant, meaning of the data, etc.

• A description of the accuracy of the measuring algorithms (e.g., price calculation and rounding algorithms).

• A description of the user interface, menus, and dialogs.

• The software identification (version, revision, etc.) and how to view it.

• An overview of the system hardware (e.g., topology block diagram, type of computer(s), type of network), 

if not described in the operating manual.

• An overview of the security aspects of the operating system, e.g. protection, user accounts, privileges, etc.

• The operating manual.
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E17

Conclusion: 

These documentation requirements will be considered as input for requirements that will eventually appear in 

NCWM Publication 14 and the application paperwork. Further work by the Sector to develop the NCWM 

Publication 14 requirements is needed, after more input from the laboratories is gathered.

8. Training of Field Inspectors 

Source: 

NTETC Software Sector

Background/Discussion: 

During discussions at the 2009 NTETC Software Sector Meeting, the Sector concluded that a new agenda item 

should be initiated specific to the training of field inspectors in relation to evaluating/validating software-based 

devices.

California has an Examination Procedure Outline (EPO) that begins to address this. Use NIST Handbook 112* as a 

pattern template for how it could read.

Items to be addressed:

• CC

• Terminology (as related to software) beyond what is in NIST Handbook 44. 

• Reference materials / information sources

• Safety

System Verification Tests

NOTE: Item numbers one through five applies to both weighing and measuring devices. Numbers six and seven are 

specific to weighing devices; while numbers nine and ten apply to measuring devices.

1. Identification. The identification (ID) tag may be on the back room computer server and could be viewed 

on an identification screen on the computer monitor. The ID information may be displayed on a menu or 

identification screen. Though currently discouraged, some systems may be designed so the system must be 

shut down and reset to view the ID information. G-S.1. (1.10.) 

1.1. Manufacturer.

1.2. Model designation.

2. Provisions for sealing. G-S.8. [1.10.]; S.1.11. [2.20.]; S.2.2. [3.30.] 

2.1. Verify sealing category of device (refer to Certificate of Approval for that system).

2.2. Verify compliance with certificate.

3. Units of measure.

3.1. A computer and printer interfaced to a digital indicator shall print all metrological values, intended to 

be the same, identically. G-S.5.2.2.(a); G-S.5.1. [1.10.] 

3.2. The unit of measure, such as lb, kg, oz, gal, qt, liters, or whatever is used, must agree.

4. Operational controls, indications and features (buttons and switches). Verify that application criteria and 

performance criteria are met (refer to Certificate of Approval).

4.1. Any indication, operation, function or condition must not be represented in a manner that interferes 

with the interpretation of the indicated or printed values.

5. Indications and displays.

5.1. Attempt to print a ticket. The recorded information must be accurate or the software must not process 

and print a ticket with erroneous data interpreted as a measured amount.

Weighing Devices

6. Motion detection.

6.1. For railway track, livestock, and vehicle scales apply or remove a test load of at least 15d while 

simultaneously operating a print button, push-button tare or push-button zero. A good way to do this is to 

try to print a ticket while pulling the weight truck or another vehicle onto the scale. Recorded values shall 
NTEP Committee 2013 Final Report

Appendix E – NTETC 2012 Software Sector Meeting Summary

NTEP - E18

not differ from the static display by more than 3d. P erform the test at 10 %, 50 % and 100 % of the 

maximum applied test load. S.2.5.1.(a) [2.20.]; EPO NO. 2-3, 2.4

6.2. For all other scales, apply or remove at least 5d. Printed weight values must agree with the static 

weight within 1d and must exactly agree with other indications. S.2.5.4.(b) [2.20.]; EPO NO. 2-3, 2.4

7. Behind zero indication.

7.1 Apply a l oad in excess of the automatic zero setting mechanism (AZSM) and zero the scale. 

S.2.1.3. [2.20.]; EPO NO. 2-3, 2.4, 2.5.2

Example: On a vehicle scale have someone stand on the scale, then zero them off (AZSM is 3d). Remove 

the weight (person) and note the behind zero display (usually a minus weight value) or error condition.

7.2. Attempt to print a ticket. With a b ehind zero condition, (manually or mechanically operated) a 

negative number must not be printed as a positive value.

8. Over capacity.

8.1. Manually enter a gross weight if permissible or apply a test load in excess of 105 % of the scale’s 

capacity. S.1.7. [2.20.]; S.1.12., UR.3.9. [2.20.] 

8.2. Attempt to print a weight ticket. A system must not print a ticket if the manually entered weight or 

load exceeds 105 % of the scale capacity.

Measuring Devices

9. Motion detection.

9.1. Initiate flow through the measuring element. Attempt to print a ticket while the product is flowing 

through the measuring chamber. The device must not print while the indication is not stable. 

S.2.4.1. [3.30.] 

10. Over capacity.

10.1. Attempt to print a ticket in excess of the indicated capacity. A system must not print a ticket if the 

device is manually or mechanically operated in excess of the indicated value.

NOTE: Be aware of error codes on the indicator, which may be interrupted as measured values.

This item is in the early stages; work will continue on the item working toward materials to aid in the training of 

field inspectors. It was indicated that working in conjunction with the Professional Development Committee (PDC)

to develop training materials, etc. would be a l ogical path of progress once we have developed the information 

content to include.

At the 2011 NTETC Software Sector Meeting, it was decided that this topic should be tabled until items 1 to 4 in the 

summary are better defined. This will also depend on the needs of and feedback from field inspectors, since the goal 

is to empower them to be better able to handle inspection of software-based devices. It was also suggested that we 

liaise with the PDC to garner input for focus areas related to the inspection of software-based devices. It was also 

noted that OIML D 31 has sections on conformance to original type approval, etc., pertaining to software.

Conclusion:

Mr. Jordan, California Division of Measurement Standards, is already doing something similar, and he may be able 

to assist. Mr. Roach, California Division of Measurement Standards, will talk to him to see whether they’re 

available. In addition Mr. Parks, California Division of Measurement Standards, is based in Sacramento, California,

and a potential resource. If the meeting is held in Sacramento next year, they may be able to attend.

Mr. Truex, NTEP Administrator, pointed out that the PDC would also be a valuable resource on this subject. 

Mr. Pettinato, Chair, will contact them.

NEW ITEMS

9. Next Meeting 

Source:

NTETC Software Sector

Background/Discussion: 

The Sector is on a yearly schedule for NTETC Software Sector Meetings. Mr. Truex, NTEP Administrator, will 

determine when the next meeting is possible. The normal rotation would have the meeting in Sacramento, 

California in 2013.

Mr. Truex, NTEP Administrator, indicated that New York has re-established their laboratory, and would be an 

alternative site for the 2013 meeting. It was also mentioned that Sacramento had the benefit of Mr. Jordan, 

California Division of Measurement Standards, and/or Mr. Parks, California Division of Measurement Standards, 

being able to attend. 

Conclusion:

The next meeting will be held either in Albany, New York, or Sacramento, California, depending on New York’s 

willingness to host and locate an acceptable meeting location. Mr. Truex, NTEP Administrator, will make the 

determination as to meeting location by the end of the year.

10. NCWM Publication 14 Proposed Changes

Source:

NTEP Administrator

Background/Discussion:

Mr. Truex, NTEP Administrator, sent the Sector membership a document outlining proposed changes to NCWM 

Publication 14’s Administrative Policy section. The purpose is not to change the intent but to clarify it. He’s asking 

for feedback on the proposed changes. Is the formatting, verbage, etc. acceptable? Does anyone have any questions 

or concerns? If so, send them to Mr. Truex. After the Sectors have reviewed it, NTEP will do so, and then it will go 

to the Board of Directors.

Conclusion:

Members are asked to review and comment on the document and provide any feedback to the Mr. Truex, NTEP 

Administrator.

The charge of the NTETC Weighing Sector is important in providing appropriate type evaluation criteria based on 

specifications, tolerances and technical requirements of NIST Handbook 44, Specifications, Tolerances, and Other 

Technical Requirements for Weighing and Measuring Devices, Sections 1.10. General Code, 2.20. Scales, 

2.22. Automatic Bulk Weighing Systems, and 2.24. Automatic Weighing Systems. The Sector’s recommendations 

will be presented to the National Type Evaluation Program (NTEP) Committee each January for approval and 

inclusion in NCWM Publication 14, Technical Policy, Checklists, and Test Procedures for national type evaluation.

The Sector is also called upon occasionally for technical expertise in addressing difficult NIST Handbook 44, 

Specifications, Tolerances, and Other Technical Issues on the agenda of National Conference on Weights and 

Measures (NCWM) Specifications and Tolerances (S&T) Committee. Sector membership includes industry, NTEP 

laboratory representatives, technical advisors, and the NTEP Administrator. Meetings are held annually, or as 

needed and are open to all NCWM members and other registered parties.

Suggested revisions are shown in bold face print by striking out information to be deleted and underlining

information to be added. Requirements that are proposed to be nonretroactive are printed in bold faced italics. 

Note: It is the policy of the National Institute of Standards and Technology (NIST) to use metric units of measurement in 

all of its publications; however, recommendations received by NCWM technical committees and regional weights and 

measures associations have been printed in this publication as submitted. Therefore, the report may contain references in 

inch-pound units.

2. Digital Electronic Scale (DES) Section 42. Zero-Load and Tare Adjustment – Monorail 

Scales Rounding of Intermediate Values in an Equation

Source: 

Mr. Steven Cook, Retired NIST Technical Advisor, OWM (2011 NTETC Weighing Sector, Agenda Item 2) 

Background/Discussion:

NCWM Publication 14 DES Section 42 Zero-Load and Tare Adjustment – Monorail Scales currently reflects 

language in NIST Handbook 44 regarding the setting of zero and tare values that are less than 5 % of the scale 

capacity to within 0.02 % of scale capacity according to NIST Handbook 44 Scales Code paragraphs 

S.2.1.4. Monorail Scales and S.2.3.1. Monorail Scales Equipped with Digital Indications. For example, a 

1000 lb × 1 lb monorail scale shall have the capability to set tare values up to 50 lb to within a resolution of 0.2 lb 

(1000 × 0.02 %). 

At the 2010 NTETC Weighing Sector Meeting, the Sector agreed to recommend that NCWM Publication 14

Section 42 be amended to clarify rounding of values by adding a new Section 42.3. stating that “rounding is not 

performed until the last mathematical operation to reduce the uncertainty of the net weight calculation.” 

The Sector also discussed the potential differences and verification of rounding when net weights are determined 

using a digital indicator's internal or displayed resolution of the gross weight. 

At the 2011 NTETC Weighing Sector Meeting, the Sector agreed that test criteria needs to be developed to verify 

whether or not scales submitted for type evaluation comply with the tare requirements in NIST Handbook 44 Scales 

Code paragraph S.2.3.1. A few members of the Sector agreed to work on developing possible test criteria that could 

be added to NCWM Publication 14 to verify whether a device submitted for type evaluation complies. It was also 

agreed that the work group would seek input from Mr. Ainsworth, U.S. Department of Agriculture (USDA)/Grain 

Inspection Packers and Stockyard Administration (GIPSA), and Mr. Vande Berg, Vande Berg Scales, when 

developing the test criteria.

Following the 2011 NTETC Weighing Sector Meeting, Mr. Cook, NIST, OWM, contacted Mr. Vande Berg for his 

input on the proposed development of procedures to determine if net weights are determined using the digital 

indicator's internal or displayed resolution of the gross weight in the calculation of the net weight and verify that tare 

weights that are smaller than the verification scale division “e” are not rounded to the value of “e” when calculating 

net weights for both static and dynamic monorail scales. It should also be noted that NIST Handbook 44 Scales 

code paragraph S.1.2.2.1. Class I and II Scales and Dynamic Monorail Scales allows Class III and unmarked 

dynamic monorail scales to have a “d” value less than “e” unlike other Class III and unmarked scales.

Mr. Vande Berg stated that he was concerned that the language recommended by the Sector in 2010 will cause a 

much more confusing issue with inspectors and packers. He was unaware of any packer that currently sends gross 

weights in 1 lb divisions and applies a 0.1 lb tare anymore. This confusion in 1997 or so was dealt with by the 

State of Nebraska and Packers and Stockyards (Mr. Onwiler and Mr. Blachford in attendance) before the provision 

allowing different values of “e” and “d” was added to NIST Handbook 44 in 1999. 

Mr. Vande Berg added that there has been little to no confusion, and he believes that this issue had been previously 

addressed and does not currently exist in the major packers since the adoption of paragraph S.1.2.2.1. The value of 

“e” in dynamic monorails is basically always 1.0 lb. There is some confusion about the value of “d” in dynamic

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F5 

monorails. Most states allow, and Packers and Stockyards encourages (in Mr. Vande Berg’s opinion a good thing), 

scales to display in 0.1 lb divisions regardless of the scale division value listed on the NTEP Certificate of 

Conformance (CCs) since the producer (cattle seller) is virtually never in attendance at the time of the transaction 

(which takes place in the packing plant so no transaction confusion due to the difference between “d” and “e” 

exists). This allows both the Packers and Stockyards inspector and the service agent the ability to more accurately 

gauge the performance of the dynamic scale during static and dynamic testing that is also recorded in 0.1 lb 

divisions. States like Illinois require scales comply with the value of “d” specified on the CC, which in Vande Berg 

Scale’s case is 0.2 lb, thus hurting both the packers maintenance people and the Packers and Stockyards inspection.

Mr. Vande Berg believes that accurately arriving at two net weight “d” values first, and then summing the net 

weights (by adding them together), makes more sense and is more in line with how MOST packers operate. Taking 

tare after adding gross weight values for cattle monorails (especially) will cause considerable trouble and in his

opinion not a good way to handle the potential rounding error problem that he doesn’t believe exists significantly in 

the field anymore. Field problems with subtraction and rounding may stem from weight indication manufacturers or 

unknowing dealers that are simply not accurately calculating net weight values because their equipment may not be 

capable of S.2.3.1. Monorail Scales Equipped with Digital Indications. (This is often the case as most indicator 

manufacturers do not understand the monorail tare requirement.) Vande Berg Scales generally insist that the tare is 

subtracted inside the indicator because of those potential rounding error issues.

Mr. Vande Berg recommended that the Sector review the language that was added to NCWM Publication 14

DES Section 42.3 to clarify that in the case of cattle, where the net weights of two half-carcasses are added together, 

the net weights of the individual weighments remain in the “d” values and that the summed weight will then be 

rounded to the value of “e”. To avoid controversy on this topic, he recommended the language in Section 42.3 be 

replaced with a statement such as “tare weight subtraction must always be done with weight values that are equal in 

division size to “d” or less of the scale.” 

Technical Advisors Note: In the case of dynamic monorail scales, d < e ≤ 10 d, as specified in Scales code 

paragraph S.1.2.2.1. Class I and II Scales and Dynamic Monorail Scales. In the case of static monorail scales, the 

value of “e” must be equal to or less than the value of “d,” as specified in paragraph S.1.2.2.2. Class III and IIII 

Scales. 

An additional recommendation made by Mr. Vande Berg was to modify the language in the first sentence of Scales 

code paragraphs S.2.3.1. Monorail Scales Equipped with Digital Indications and S.2.1.4. Monorail Scales by adding 

the words “at least” to the first sentence of each paragraph so that the ending portion of those sentences would read 

as follows: 

“means shall be provided for setting the zero-load balance to within at least 0.02 % of scale capacity.” 

The Sector may wish to consider Mr. Vande Berg’s additional recommendation as changing the language of these 

two NIST Handbook 44 paragraphs may impact the application of NCWM Publication 14 DES Section 42.1. 

Since there have been few rounding problems discovered by Packers and Stockyards since the issue was raised in 

2010, the Sector may want to discuss the need for developing additional procedures to determine if net weights are 

determined using the digital indicator's internal or displayed resolution of the gross weight in the calculation of the 

net weight, and verify that tare weights that are smaller than the verification scale division “e” are not rounded to the 

value of “e” when calculating net weights for both static and dynamic monorail scales. 

Mr. Vande Berg recommended the following changes to NCWM Publication 14, Section 42: 

42. Zero-Load and Tare Adjustment – Monorail Scales

Code References: S.2.1.4. and S.2.3.1.

Under the regulations of the Packers and Stockyards Administration, the rollers and hooks used on monorail 

scales within a facility are required to be nearly the same weight. Since dynamic monorail scales typically 

have scale verification (e) divisions of 1 lb, a monorail scale must be capable of setting tare weights that are

less than 5 % of the scale capacity to a weight value less than the displayed scale division. This reduces the 

rounding error in the tare weight that would otherwise be present if the tare weight were rounded to the 

nearest displayed scale division.

2.1. Means must be provided for setting the zero-load balance and any tare 

value less than 5 % of the scale capacity to within 0.02 % or less of scale

Conclusion: 

Mr. Vande Berg, Vande Berg Scales, and Mr. Arce, GIPSA, were present at the 2012 WS meeting to assist in 

explaining and answering questions relative to this item. They reviewed with members of the WS some of the more 

typical procedures used by U.S. meat packing companies to determine the weight of animal carcasses obtained from 

monorail scale systems of varying design. As part of that discussion, they also identified some concerns they had 

relative to some of the weighing practices and designs of some of the monorail scale systems. Two main concerns 

were identified and discussed: 

1. The additional rounding error caused by weighing two halves of an animal carcass separately on a scale 

with digital indication, and

2. The taking of tare to an increment different from the displayed scale division. 

The WS considered whether any of the current requirements in HB-44 might already address the concerns raised by 

Mr. Vande Berg and Mr. Arce and concluded that they did not. It was then suggested, and the WS agreed, that 

NIST Handbook 44 should first be amended, rather than NCWM Publication 14, because the evaluation criteria in 

NCWM Publication 14 is intended to determine whether or not equipment submitted for type evaluation complies 

with NIST Handbook 44 requirements. T hus, it would be inappropriate to develop type evaluation criteria to 

address issues that have no corresponding NIST Handbook 44 requirement. For this reason, the WS agreed to take 

no action on the item pending possible future changes to NIST Handbook 44. Mr. Vande Berg and Mr. Arce agreed 

to develop, with the assistance of Mr. Harshman, NIST Technical Advisor, an NCWM Form 15 proposal to amend 

NIST Handbook 44 and address all concerns.

Background/Discussion: 

Local weights and measures inspectors need a means to determine whether equipment discovered in the field has 

been evaluated by NTEP. If so, the inspector needs to know at a minimum the CC number. From this starting point, 

other required information can be ascertained. NIST Handbook 44 currently includes three options for marking of 

the CC:

At the 2011 NCWM Annual Meeting, the S&T Committee agreed to change the status of this item to Developing 

because the item was lacking enough information for full consideration and a full proposal has yet to be developed.

At the 2011 NTETC Weighing Sector Meeting, the Sector agreed to take no additional action on this item pending 

further development of the item by the NTETC Software Sector.

During the 2012 Software Sector Meeting, Mr. Truex, NTEP Administrator, discussed the difficulty there has been 

in coming to a consensus on these issues with a representative of the NTEP Committee. Suggestions from NTEP to 

come to some resolution has been to write an article for the newsletter (which Mr. Bliss, Mettler-Toledo, LLC, had 

already done, to no effect), sending a questionnaire to the NTEP community, asking what they’d like to see, and 

sending a representative from this Sector to the S&T Committee. 

Mr. Roach, California Division of Measurement Standards, was concerned that some people may want to interpret 

G-S.1.(c) as requiring a serial number for software. Mr. Lewis, Rice Lake Weighing Systems, Inc. pointed out that 

the computer that the software was running on could have the serial number, not the software itself. That shouldn’t 

matter, regardless. 

Mr. Bliss, Mettler-Toledo, LLC, pointed out that the terminology in G-S.1., “All equipment” could be interpreted to 

mean that it doesn’t apply to software. It was proposed that G-S.1.(c) be amended to add “and software.” Mr. Bliss 

suggested submitting a document explaining the reasoning behind the proposed changes, rather than assume that the 

text is self-explanatory. Making a p resentation to the various Committees on the subject in addition would be 

beneficial as well. If a document is written, perhaps the examples given in G-S.1.(d)(3)(a) can be eliminated. 

“Metrologically significant” isn’t explicitly defined, but it’s been used since time immemorial.

Attempts to modify G-S.1.1. have been controversial, both in this meeting and in other committees. Unfortunately,

there has been little constructive feedback from the other committees. It would probably be easier to incorporate

specific examples given in G-S.1.1.(b)(3) in NCWM Publication 14. After some discussion, the previously 

proposed language was modified slightly to address some of the concerns received via feedback from other Sectors 

and interested parties:

NIST Handbook 44 – Software Sector Proposed modifications to 2012 NCWM Publication 16 Developing Item 

360-2 G-S.1. Identification. (Software) Proposed modifications are described below and shown in shaded text): 

The Software Sector modified the Developing item by deleting the proposed additional language in the first sentence in 

paragraph G-S.1. to read as follows:

G-S.1. Identification. – All equipment, except weights and separate parts necessary to the measurement process but not 

having any metrological effect, and software-based devices covered in G-S.1.1. Location of Marking Information*, shall 

be clearly and permanently marked for the purposes of identification with the following information: 

(a) the name, initials, or trademark of the manufacturer or distributor; 

(b) a model identifier that positively identifies the pattern or design of the device; 

(1) The model identifier shall be prefaced by the word “Model,” “Type,” or “Pattern.” These terms may be 

followed by the word “Number” or an abbreviation of that word. The abbreviation for the word “Number” 

shall, as a minimum, begin with the letter “N” (e.g., No or No.). The abbreviation for the word “Model” 

shall be “Mod” or “Mod.” Prefix lettering may be initial capitals, all capitals, or all lowercase.

(Added 2000) (Amended 2001) 
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F8 

The Software Sector modified the Developing item by replacing the proposed reference to “software-based electronic 

devices” with the single word “software” to read as follows:

(c) a nonrepetitive serial number, except for equipment with no moving or electronic component parts and not-built-forpurpose software-based electronic devices software;

[Nonretroactive as of January 1, 1968] 

(Amended 2003) 

(1) The serial number shall be prefaced by words, an abbreviation, or a symbol, that clearly identifies the number as 

the required serial number. 

[Nonretroactive as of January 1, 1986] 

(2) Abbreviations for the word “Serial” shall, as a minimum, begin with the letter “S,” and abbreviations for the 

word “Number” shall, as a minimum, begin with the letter “N” (e.g., S/N, SN, Ser. No., and S. No.). 

[Nonretroactive as of January 1, 2001] 

The Software Sector modified the Developing item by deleting the proposed reference to “software-based electronic 

devices” to read as follows:

(d) the current software version or revision identifier for not-built-for-purpose software-based electronic devices; 

[Nonretroactive as of January 1, 2004] 

(Added 2003) (Amended 20XX)

(1) The version or revision identifier shall be prefaced by words, an abbreviation, or a symbol, that clearly 

identifies the number as the required version or revision. 

[Nonretroactive as of January 1, 2007] 

(Added 2006) 

(2) Abbreviations for the word “Version” shall, as a minimum, begin with the letter “V” and may be followed by 

the word “Number.” Abbreviations for the word “Revision” shall, as a minimum, begin with the letter “R” 

and may be followed by the word “Number.” The abbreviation for the word “Number” shall, as a minimum, 

begin with the letter “N” (e.g., No or No.). 

[Nonretroactive as of January 1, 2007] 

(Added 2006) 

The Software Sector modified the Developing item by adding a new subparagraph G-S.1. (d) (3) to read as follows:

(3) The version or revision identifier shall be accessible via the display. Instructions for displaying the version 

or revision identifier shall be described in the CC. As an exception, permanently marking the version or 

revision identifier shall be acceptable under the following conditions:

(a) The user interface does not have any control capability to activate the indication of the version or 

revision identifier on the display, or the display does not technically allow the version or revision 

identifier to be shown (analog indicating device or electromechanical counter) or

(b) the device does not have an interface to communicate the version or revision identifier.

(e) an NTEP CC number or a corresponding CC Addendum Number for devices that have a CC. 

(1) The CC Number or a corresponding CC Addendum Number shall be prefaced by the terms “NTEP CC,” 

“CC,” or “Approval.” These terms may be followed by the word “Number” or an abbreviation of that word. 

The abbreviation for the word “Number” shall, as a minimum, begin with the letter “N” (e.g., No or No.) 

[Nonretroactive as of January 1, 2003] 

The required information shall be so located that it is readily observable without the necessity of the disassembly of a part

requiring the use of any means separate from the device.

(b), and (e)” in paragraph G-S.1.1. (a) to read as follows:

(a) The required information in G-S.1. Identification. (a), (b), (d), and (e) (a), (b), (d), and (e) shall be permanently 

marked or continuously displayed on the device; or 

(b) The CC Number shall be: 

(1) permanently marked on the device; 

(2) continuously displayed; or 

(3) accessible through an easily recognized menu and, if necessary, a submenu. Examples of menu and submenu 

identification include, but are not limited to, “Help,” “System Identification,” “G-S.1. Identification,” or 

“Weights and Measures Identification.” one or, at most, two levels of access. 

(i) For menu based systems, “Metrology,” System Identification,” of “Help.”

(ii) For Systems using icons, a metrology symbol “(M),” (SI),” or a help symbol (“?,” “I,” or and “I” within a 

magnifying glass). 

Note: For (b), clear instructions for accessing the information required in G-S.1. (a), (b), and (d) shall be listed on the CC, 

including information necessary to identify that the software in the device is the same type that was evaluated. 

[Nonretroactive as of January 1, 2004] 

(Added 2003) (Amended 2006 and 20XX) 

The new language in G-S.1.1. reflects that the Sector reached consensus on the following positions:

• The software version/revision should (with very few exceptions – see D-31 5.1.1) be accessible via the user 

interface.

• The means by which the software version is accessed must be described in the Certificate of Conformance 

(CC).

In addition, it was asserted that the previously recommended changes to G-S.1.1.(b)(3) in fact are not really 

necessary; the current language of NIST Handbook 44 empowers the laboratories to enforce “easily recognizable” as 

they see fit. I n fact, the previously generated “list” of icons and menu options could certainly be used by the 

examining laboratories as part of the approval process (e.g., in NCWM Publication 14). Of course, a manufacturer 

who is reviewing NIST Handbook 44 so as to develop an acceptable device may benefit from more explicit 

guidance. Where does such guidance belong? 

Comments related to the circulated list included a co mment from the Scale Manufacturers Association (SMA) 

suggesting that a definition is needed for “software-based devices.” SMA opposed the definitions previously put 

forth by the Sector. I t was suggested that perhaps SMA would be more amenable to a definition that doesn’t 

differentiate between software types. 

Since this item is currently defined as a Developing Item, it cannot be moved to a Voting Item at the 2012 NCWM 

Annual Meeting; it will have to wait until 2013. In January of 2013, the item will be reviewed and a decision will be 

made whether or not to change the status of this item. To upgrade the status of this item, the Sector will need to 

explain the intent behind the proposed changes to G-S.1. and G-S.1.1. 

Conclusion:

It was reported that the Software Sector is still actively working on this item and that during the SMA meetings in 

April 2012 a member of that Sector was present and had circulated that Sector’s proposed modifications to members 

of the SMA for input. The general view of most members of the SMA was favorable towards the proposed changes. 

Members of the WS were then offered the opportunity to provide an opinion on the modifications proposed, but no 

one opted to do so. The WS agreed to take no additional action on this item pending further development of the 

item by the Software Sector.

Mr. Luthy, Stock Equipment Company, Inc. (2011 NTETC Weighing Sector Agenda Item 6)

Background/Discussion: 

During the 2011 NTETC Weighing Sector Meeting, the Sector discussed a weigh in-motion system using new 

technology that utilizes continuous rails (no “rail gaps”) on the approaches and weighing areas of the scale. The 

submitter stated that the manufacturer was unable to offer this device for sale in the United States in commercial 

applications because current NTEP type evaluation criteria and NIST Handbook 44 requirements were written in 

such a way that makes it impossible for devices incorporating this new technology to comply. For example, NIST 

Handbook 44, Scales Code paragraph UR.2.4. Foundations, Supports, and Clearance requires clearance be provided 

around all live parts to the extent that no contacts may result. NCWM Publication 14, DES Section 70, Inspect the 

Scale, Item 4 Rail Gaps states that “the rail gaps should be set at 3

/8 inch.” The AAR Scale Handbook includes 

language that allows 1

/8 inch to 5/8 inch rail gaps.

The members of the Sector agreed that they were not willing to recommend deleting references to the required gaps 

in the rail until it is proven that the new technology complies with the tolerances in NIST Handbook 44. Thus, the 

Sector recommended that the applicant move forward with performance testing to confirm that the new technology 

complies with the tolerances in NIST Handbook 44. The Sector agreed that data resulting from the performance 

testing needed to be submitted to the Sector prior to the time that the 2012 NTETC Weighing Sector Agenda was

developed or the item should not be included as a carryover item on that agenda.

during its 2011 meeting go to: ncwm.net/content/weighing-archive

Conclusion: 

Mr. Luthy, Stock Equipment Co., provided a brief update on the progress of the performance testing to date. He 

reported that ongoing testing is still being conducted at the Association of American Railroads (AAR) 

Transportation Technology Center near Pueblo, Colorado. Because the testing is still ongoing, the WS agreed to 

Mr. Luthy’s request to maintain the item as a Carryover item on the 2013 N TETC Weighing Sector Agenda 

providing a report resulting from the testing is submitted to the Sector prior to the time that the 2013 NTETC 

Weighing Sector Agenda is developed. O therwise, the item should not be included as a Carryover item on the 

2013 WS Agenda. 

5. DES Appendix C- Acceptable Abbreviations for Short Ton and Long Ton 

Source: 

Mr. Lewis, Rice Lake Weighing Systems, Inc. (2011 NTETC Weighing Sector Agenda Item 8)

Background/Discussion: 

At the 2011 NTETC Weighing Sector Meeting, Mr. Lewis, Rice Lake Weighing Systems, Inc., recommended

adding “tn” as an acceptable abbreviation for a U.S. short ton to the current list of acceptable abbreviation of “Ton” 

or “TN.” Mr. Lewis is also recommended that “lt” be added to the list of acceptable abbreviations for a long ton. 

He added that the Canadian Lab Manual, Part 2, Section Appendix-2A in the table for abbreviations and symbols 

accepted in Canada, metric ton is abbreviated by “t” and ton (short ton) is abbreviated by “tn.”

The Sector agreed to add “tn” to the table of Acceptable Abbreviations in Appendix C of NCWM Publication 14 as 

an acceptable abbreviation for short ton. Mr. Harshman, NIST Technical Advisor, noted that the abbreviation “tn” 

does not exist in Appendix C of NIST Handbook 44 nor in NIST SP 811, Guide for the Use of the Inernational 

System of Units (SI), and this change recommended by the Sector, if approved, would add the abbreviation to only 

one portion of NCWM Publication 14 table, that is, to the portion titled “Exceptions to General Tables” of NIST 

Handbook 44. The Sector also agreed to delay taking any action on adding the abbreviation “lt” for long ton until 
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F11

the S&T Committee has had an opportunity to consider the proposal from Mr. Lewis, Rice Lake Weighing Systems, 

Inc., to amend NIST Handbook 44 by adding the abbreviations “tn” for short ton and “lt” for long ton. 

At the 2012 NCWM Interim Meeting, the original submitter, Mr. Lewis, Rice Lake Weighing Systems, Inc., 

requested that the proposal in the Interim Agenda be modified to remove the reference to long ton and its associated 

proposed abbreviation “lt.” Mr. Lewis indicated that the intent of the proposal is to align United States and 

Canadian requirements and noted that the abbreviation “tn” is an acceptable Canadian abbreviation for short ton. 

Mr. Flocken, speaking on behalf of the SMA, suggested making the item Informational to allow for more discussion. 

He stated that SMA supports the abbreviation “tn” for short ton but not the long ton abbreviation “lt.”

Mr. Ripka, Thermo Fisher Scientific, indicated that several different references for ton (short) have been used with 

belt-conveyor scale systems over the years. For example, both lower case “t” and upper case “T” have been used to 

abbreviate short ton. He stated that although he was not opposed to the item, more work is needed to ensure that 

references are consistent throughout all of NIST Handbook 44. 

The S&T Committee considered the comments received during the Open Hearings and agreed with the 

recommendation to amend the Units of Mass table on page C-19 of NIST Handbook 44, Appendix C as shown in 

Item Under Consideration. The Committee agreed that additional work was needed on this item. The Committee

asked the NIST Technical Advisors to undertake a review of the references in NIST Handbook 44, the Canadian 

requirements, and NCWM Publication 14, and identify any additional changes that might be needed to ensure 

consistency. Additionally, the Committee is seeking input from the community on the impact that this item might 

have on existing scales in the marketplace. The 2012 S&T Committee designated this item as an Informational 

Item. 

After the 2012 NCWM Interim Meeting had concluded, NIST, OWM, in reviewing summary comments from the 

2011 SWMA fall meeting, discovered an additional reference on page C-6 of Appendix C, NIST Handbook 44 that 

SWMA had identified as needing to be changed in order to be consistent with the change proposed in the Item 

Under Consideration. N IST, OWM suggested that the Committee consider the following changes for future 

consideration of this item: 

Amend the abbreviation “t” representing the “net” or “short” ton on page C-6 of NIST Handbook 44 Appendix C to 

“tn” as follows: 

Avoirdupois Units of Mass6

[The “grain” is the same in avoirdupois, troy, and apothecaries units of mass.]

1 μlb = 0.000 001 pound (lb)

2711/32 grains (gr) = 1 dram (dr)

16 drams = 1 ounce (oz)

= 4371⁄2 grains

16 ounces = 1 pound (lb)

= 256 drams

= 7000 grains

100 pounds = 1 hundredweight (cwt)7

20 hundredweights = 1 ton (tn)

= 2000 pounds7

In “gross” or “long” measure, the following values are recognized:

112 pounds (lb) = 1 gross or long hundredweight (cwt)7

20 gross or long hundredweights = 1 gross or long ton

= 2240 pounds
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F12

6 When necessary to distinguish the avoirdupois dram from the apothecaries dram, or to distinguish the avoirdupois dram or 

ounce from the fluid dram or ounce, or to distinguish the avoirdupois ounce or pound from the troy or apothecaries ounce or 

pound, the word “avoirdupois” or the abbreviation “avdp” should be used in combination with the name or abbreviation of 

the avoirdupois unit. 7 When the terms “hundredweight” and “ton” are used unmodified, they are commonly understood to mean the 100 pound 

hundredweight and the 2000-pound ton, respectively; these units may be designated “net” or “short” when necessary to 

distinguish them from the corresponding units in gross or long measure.

Additional letters, presentations, and data may have been part of the Committee’s consideration. P lease refer 

to www.ncwm.net/content/2012pub-16 to review these documents.

At the 2012 NCWM Annual Meeting, the Committee acknowledged that the reference to “lt” is no longer under 

consideration. Mr. Darrell Flocken, speaking on behalf of SMA, reiterated the comments he made at the Central 

Weights and Measures Association (CWMA) meeting and supported changing the item to Informational.

NIST, OWM noted that the 2011 NCWM Publication 14 Belt-Conveyor Scale Systems type evaluation criteria 

provides a table on page BCS-4 that indicates the U.S. short ton may be identified as “ton” or upper case “T;” the 

metric ton as lower case “t;” and the U.S. long ton as upper case “LT.” The following abbreviations appear in the 

2011 version of NCWM Publication 14 BCS systems type evaluation criteria: 

Unit Abbreviation

pounds lb or LB

U.S. short ton ton or T

U.S. long ton LT

Metric ton t

kilograms kg

The abbreviation “T” for U.S. short ton in NCWM Publication 14 conflicts with the acceptable abbreviation for the 

U.S. short ton specified in Appendix C of NIST Handbook 44, which is “t.” A search of the word “ton” in 

Appendix C of NIST Handbook 44 revealed that nowhere is upper case “T” used, although lower case “t” appears as 

an acceptable abbreviation for both the U.S. short (or net) ton (page C-6) and the metric ton (page C-19). NIST, 

OWM is concerned that officials applying paragraph G-S.5.6.1. might be inclined to reject an upper case “T” as an 

acceptable abbreviation for the U.S. short (or net) ton even though NCWM Publication 14 indicates that the upper 

case “T” is acceptable. O fficials might also find it confusing if lower case “tn” were made an acceptable 

abbreviation for the U.S. short or net ton, given that the table on page BCS-4 of NCWM Publication 14 specifies 

lower case “t” as the acceptable abbreviation for the metric ton. 

NIST, OWM noted that even if everyone were to agree on different acceptable abbreviations for the U.S. short or 

net ton, the U.S. long ton, and the metric ton, it is not likely that this would completely resolve all the confusion 

relating to the value of the ton in commercial transactions. The spelled-out version of the word “ton” is often used 

instead of its abbreviation to identify values displayed or recorded by a commercial device. Thus, unless the word 

“ton” is further qualified using an appropriate clarifying preface such as metric, short, net, or long, it’s unclear as to 

which ton is being referenced when the word “ton” by itself is used to identify the unit of measure. 

NIST, OWM suggested that the Committee consider changing the abbreviation “t” (which refers to 1 ton (short), 

beneath the heading “Avoirdupois Units of Mass” on page C-6 of the 2012 version of NIST Handbook 44) to “tn” to 

avoid conflict with the recommended proposal. NIST, OWM also noted that the abbreviation “lt” was erroneously 

left in the table.

The Committee agreed that the “lt” abbreviation for “1 ton, gross or long” in the table on page S&T 20 of 2012 

NCWM Publication 16 was erroneously left in the table from the original proposal and should be removed.
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F13

The Committee reiterated its request for input from the community on the impact that this item might have on 

existing scales in the marketplace and asks for input regarding what additional changes might be needed to the 

proposal prior to moving it forward.

The Committee recommended deleting the reference to “Long Ton” in the “Purpose” so that it reads as follows:

“Purpose: Establish uniform abbreviations for Short Ton.”

The Committee also recommended deleting the reference to “lt” in the “Units of Mass” table in the “Item Under

Consideration” so that the reference for “1 ton, gross” reads as follows:

1 ton, gross or long19

Conclusion: 

Mr. Harshman, NIST Technical Advisor, reviewed background associated with this item and reported that prior to 

the 2012 NCWM Annual Meeting, Mr. Ripka, Thermo Ramsey had expressed a concern that field officials might 

find it confusing if lower case “tn” were adopted as an acceptable abbreviation for short or net ton because the 

abbreviation “t” is considered an acceptable abbreviation for metric ton in NCWM Publication 14 BCS. He also 

pointed out that even if the abbreviation “tn” was adopted, this would not clear up all the confusion surrounding the 

value of the ton in commercial transactions. In cases where the word ton is spelled out and no abbreviation is used, 

additional qualifying words are needed to identify which ton is being referenced. Mr. Lewis, Rice Lake Weighing 

Systems, Inc., commented that the proposal was intended to harmonize U.S. and Canadian requirements, noting that 

Canada accepts “tn” as an acceptable abbreviation for short ton. Mr. Flocken, Mettler-Toledo, Inc., added that the 

change would make it easier for scale manufacturers if they could manufacture scales using a s ingle acceptable 

abbreviation. Mr. Luciano Burtini, MC, stated that upper case “T” is not permitted as an acceptable abbreviation for 

short or net ton as it is in NCWM Publication 14 BCS. The lower case “tn” is the acceptable Canadian abbreviation 

for short ton and lower case “t” is the acceptable abbreviation for metric ton. Mr. Harshman, NIST Technical 

Advisor, will forward the Sector’s comments and recommendations to the appropriate regional and NCWM 

Committees for their consideration and comments.

6. Sealing/Capabilities of Smart Junction Boxes 

Source: 

Mr. Payne, Maryland Department of Agriculture (2011 NTETC Weighing Sector Agenda Item 11)

Background / Discussion: 

At the 2011 N TETC Weighing Sector Meeting, Mr. Payne, Maryland Department of Agriculture, requested the 

Sector’s guidance on the proper means of sealing, and assistance in determining the capabilities of a “smart junction 

box,”(aka “smart “J” box”) which was about to be submitted to the Maryland Laboratory for NTEP certification. 

Although not confirmed, it was Mr. Payne’s belief (based on discussions with an equipment manufacturer) that the 

“smart junction box” provided a means of remotely accessing calibration and/or configuration adjustments once 

installed in a scale. 

Mr. Truex, NTEP Administrator, pointed out that such adjustments can generally only be carried out through the 

indicator of a weighing system comprised of separable components (i.e., an indicator, weighing/load-receiving 

element, and load cells). NTEP evaluates each of these components separately, issuing a s eparate CC for each 
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F14

component once that component has passed type evaluation criteria. Notations made on the CC by the evaluator 

typically provide an indication of the compatibility and/or non-compatibility of a component with other separable 

components.

During the discussion, it was mentioned that several U.S. scale manufacturers, including some who were represented 

in the room, design and manufacture smart “J” boxes. Mr. Flocken, Mettler-Toledo, LLC, noted that internationally, 

as many as seven different components of a scale are type evaluated using test criteria contained in International 

Organization of Legal Metrology (OIML) Recommendations. He questioned whether the Sector might want to 

further research the capabilities of “smart “J” boxes” and possibly consider developing type evaluation criteria to 

evaluate them as separate component of a weighing system. 

The Sector agreed to form a small work group to study the capabilities of this equipment and determine whether or 

not type evaluation criteria should be developed to evaluate them as a separate component. Mr. Harshman, NIST, 

OWM agreed to organize the first teleconference to review the requirements for a Smart Junction Box. 

Additionally, the Sector agreed that, the term “smart junction box” refers to a d evice that contains active 

components and used to digitize the output of one or more analog load cells. The box may include a processing 

component with or without software to scale or calibrate the digitized output. T he box transmits the weight 

information to an indicating element either via a wireless or wired connection.

During the discussion of the November 3, 2011, teleconference, there was general agreement that, because the 

junction box contained active elements, it should be tested for environmental influence factors as described in NIST 

Handbook 44 Scales Code paragraph T.N.8. It was also determined that there are two basic types of smart junction 

boxes; those that only digitize the load cell signal(s) and those that digitize and then calibrate the load cell signal(s). 

It was concluded that checklist procedures and language will be developed to describe the evaluation of this device 

type and that this would be submitted to the NTETC Weighing Sector at their next regularly scheduled meeting. To 

accomplish this, a workgroup would be formed. T he workgroup would be made up of device manufacturers, 

representatives of NIST, OWM and NTEP, and lab personnel. Mr. Langford, Cardinal Scale Manufacturing Co.,

volunteered to serve as the ad hoc chair of the workgroup and indicated the first step would be to develop a list of 

the devices of this type already assigned NTEP CCs. Mr. Harshman, NIST, OWM provided the contact information 

for the participants at the teleconference.

The draft procedures and discussions were developed, reviewed, and agreed upon by the work group by the end of 

December 2011 and submitted to Mr. Truex, NTEP Administrator, and Mr. Harshman, NIST, OWM for discussion 

at the 2012 NTETC Weighing Sector Meeting. 

For additional background information relative to this item and actions taken by the NTETC Weighing Sector 

during its 2011 meeting go to: ncwm.net/content/weighing-archive

Conclusion: 

Members of the Sector, including the NTEP evaluators who were present at the meeting, voiced support to adding 

the draft evaluation criteria to NCWM Publication 14. During the discussion, it was noted that the draft document 

was developed and borrowed heavily from criteria already existing in NCWM Publication 14. The Sector agreed 

that the draft type evaluation criteria should be recommended for addition to the DES portion of NCWM 

Publication 14 as a new Section 76 and that its title should be “Digital Controller Element for Load Cells.” This 

new section should also be referenced in the DES Table of Contents beneath the heading titled: “Checklists and Test 

Procedures,” as a new Section 76. The draft evaluation criteria recommended for insertion into NCWM 

Publication 14 can be found in the Attachment section of this summary and is titled: Attachment to agenda Item-6: 

Sealing/Capabilities of Smart Junction Boxes.

Source:

NTEP Administrator

Background/Discussion: 

The NTEP Administrator was contacted by an individual questioning tolerance values for repeatability and creep 

shown in the example summary table in NCWM Publication 14 – Load Cells Table 6 “Example of a Summary Table

for a Class III 3000 Single Load Cell” (the reported errors are shown in Table 6 in shaded text). The individual 

reported that: 

1. The tolerance listed on the table should be the value from Table 3 - Tolerance for Class III Load Cells, page 

LC-10. That is, the repeatability error of a Class III 3000 single cell requirement (from Table 3) should be 

0.7v (0-500v); 1.4v (501-2000v); 2.1v (2001-4000v); 3.5v (4001-10 000v), so the value of repeatability 

error shown on Table 6 should be other than 0.35v. 

2. Similar error on Creep (time dependence) of Table 6, the value should follow the mpe Table T.N.4.6., the 

value of creep shown on Table 6 should be 1.05v other than 1.5v.

3. Same error on Creep change (I20min-I30min) of Table 6, according to Table T.N.4.6., it should be 0.1575v 

(0.15 x mpe) other than 0.225v.

The Sector was asked to review the information provided by Mr. Truex, NTEP Administrator, and agree on an 

appropriate recommendation to address the reported inaccuracies in NCWM Publication 14 Load Cells Table 6 – 

Example of a Summary Table for a Class III 3000 Single Load Cell (e.g., correcting or deleting Table 6, or other 

possible solutions). 

Conclusion: 

Mr. Truex, NTEP Administrator, reported that NCWM Publication 14 Load Cell Table 6 had been created a very 

long time ago and that the validity of some of the values in the table was currently being questioned. He supported 

maintaining the table in NCWM Publication 14 and asked that the load cell experts from the WS verify the 

correctness of the values being questioned. Members of the WS reviewed the values in Table 6 and could not 

determine how some of the values were determined or derived. Consequently, the WS agreed to maintain this item 

as a Carryover item on their 2013 agenda to allow additional time for input from load cell experts. It was agreed 

that Mr. Rusk, Coti Global Sensors; Mr. Upright, Vishay Transducers, Inc.; Mr. Flocken, Mettler-Toledo, Inc.; 

Mr. Langford, Cardinal Scale Manufacturing, Inc.; and Mr. Harshman, NIST, OWM, would consult with load cell 

experts in an effort to verify and make corrections to the values in the table where needed. Mr. Harshman offered to 

consult with Mr. Chesnutwood, NIST Force Lab, regarding this effort. 

Shortly after the 2012 WS meeting had concluded, Mr. Chesnutwood provided a review of the values in Table 6 and 

made corrections where necessary. A corrected version of the table, shown below, incorporating 

Mr. Chesnutwood’s changes, was then circulated to all members of the Sector who were in attendance at the 2012 

WS meeting. Me mbers were asked to vote on whether the corrections to the values in the table should be 

completed or the item remain as a Carryover item on the 2013 WS agenda. All members responding to the poll, 

with the exception of one member choosing to abstain, voted in favor of making the corrections included in the 

table. For this reason, it was decided that the corrected version of the table would be submitted to the NTEP 

Committee in January 2013 with the recommendation from the WS that it be included in the next version of NCWM 

Publication 14. Three members of the WS representing load cell manufacturers did not respond to the poll that was 
NTEP Committee 2013 Final Report

taken. Because those three represented a majority of the load cell manufacturers present during the WS meeting, it 

was decided that the item would still remain as a Carryover item on the 2013 WS agenda to provide additional 

confirmation by the WS, including more desired representation by the load cell manufacturers, that the changes 

made to the table were correct.

8. NCWM Publication 14, NTEP Administrative Policy 

Source

NTEP Administrator

Background/Discussion

NCWM is working to revise NCWM Publication 14, Administrative Policy to put it in a more logical order and 

more understandable form. The purpose is not to change the intent of the publication, rather to realign and clarify 

sections as necessary. Sectors, Committees, and the NTEP labs are asked to review the revised section, “NTEP 

Administrative Policy” and provide feedback.

Conclusion: 

Mr. Truex reported that the NTEP Board of Directors maintains responsibility of NCWM Publication 14, 

Administrative Policy and that this document had been recently revised and is currently in draft form. A copy of the 

draft revision was provided to members of the Sector and they were asked to provide a r eview and report any 

concerns to Mr. Truex prior to the NTEP Committee meeting planned in early October 2012. Mr. Harshman, 

OWM, commented that he noticed that the revised draft uses the acronym WMD to reference the NIST Office of 

Weights and Measures and that a global search of the document should be performed to correct this oversight. The 

draft revision of NCWM Publication 14, Administrative Policy can be found in the NTETC Sector Section of the 

www.ncwm.net website. 

9. Next Sector Meeting

The WS agreed to conduct their next meeting in Albany, New York, on Tuesday and Wednesday, August 27 and 28, 

2013. Mr. Morabito, New York State Weights and Measures, was asked by Mr. Truex to provide the names of three

hotels in the area to accommodate members of the Sector during their visit. Mr. Morabito stated that Mr. Sikula, 

Director of New York State Weights and Measures, hopes to be able to offer a tour of the new lab at that time.

Digital Controller Element for Load Cells

Checklists and Test Procedures

Revision A – Dec 28, 2011

Purpose and Use

This checklist is intended for use when conducting NTEP evaluations of new Digital Controller Elements (DCE) for 

Load Cells. A DCE for Load Cells is defined as a d evice that accepts the analog output of one or more cells, 

converts the load cell output(s) to a single digital value and transmits that value to a display element where it is 

either displayed or processed further before display. T he DCE is typically housed in a s eparate enclosure and 

located adjacent to the load cell(s). Calibration of the digital weight signal can take place either within the Digital 

Controller or within the Digital Weight Indicating (DWI) element. Block diagrams of the three possible types of 

Load Cell Digital Controller are shown below:

These checklists and test procedures apply if NTEP Certification is ONLY for this portion of the instrument.

If NTEP Certification is for the signal conditioning element and the DWI element (the whole weight indicating 

element), use the Digital Electronic Scales (DES) examination procedure.

NTEP Certification is not required for the DCE. 

NTEP Certification is required for the DCE.

If both the DCE AND the associated DWI Element are being evaluated as a single component, the test and checklist 

for Digital Electronic Scales should be used. I f only the DCE is being evaluated, use this checklist and test 

procedure.

The checklist is designed so that the user can determine and record the conformance of the device with the elements 

of NIST Handbook 44 in a logical sequence. The user should make copies of the checklist to serve as work sheets, 

preserving the original for reference. In most cases, the results of evaluation for each element can be recorded by 

checking the appropriate response. In some cases the user is required to record values, results or comments. In 

those cases, space is provided.

1. Marking Requirements

Code Reference: To Be Determined

The minimum information to be marked on the Load Cell Digital Controller Element (DCE) includes the 

manufacturer’s ID, the Model Number and Prefix, the Serial Number and Prefix and the Certificate of Conformity 

Number (CC). If the DCE is intended to operate accurately over a temperature range that is narrower than – 10 °C 

to 40 °C (14 °F to 104 °F) then the operating temperature range must also be marked on the device. If a narrower 

temperature range is specified, the range must be at least 54 °F (30 °C). If the DCE contains calibration and setup 

information to calibrate the weight signal before transmission, it must also contain markings for the accuracy class 

and n-max. T he display element used to display the weight value from this device must contain markings for 

manufacturer’s ID, the Model Number and Prefix, the Serial Number and Prefix, the Certificate of Conformity 

Number (CC), the temperature range if not – 10 °C to 40 °C (14 °F to 104 °F), the Nominal Capacity, the Value of 

the Scale Division “d”, and the value of “e” (required only if different than “d”).

The lettering must be permanent as described in section 1.

2. Provision for Metrological Sealing of Adjustable Components or Audit Trail

Code Reference S.1.11.

All components of a weighing instrument must comply with Section 10 of the Digital Electronic Scale Checklist if 

they have a metrological effect on the instrument or system. DCE features, not addressed in this checklist, may be 

covered and shall comply with applicable sections in the Digital Electronics Scales Checklist. (See Appendix A – 

Philosophy for Sealing, Typical Features and Parameters to be Sealed)

Only those DCEs that contain sealable parameters are required to have a means of sealing the adjustments or contain 

an Audit Trail feature. T hose DCEs that ONLY digitize the load cell signal and do not contain any sealable 

parameters are not required to have security seals or Audit Trails. 

Verify that the Digital Controller Element (DCE) does NOT have sealable parameters and cannot adjust the 

accuracy of the weighing instrument.

3. Test Procedures for Influence Factors

Introduction

Influence factors are environmental variables that might affect the performance of the DCE. Section T.N.8. of the 

Scales Code in NIST Handbook 44 specifies performance requirements for scales and scale components over given 

ranges. T he test equipment (e.g., thermometers, hygrometers, timing devices) must be sufficiently accurate that 

their errors do not significantly contribute to the measurement results. The environmental chamber used must meet 

specified conditions as well. In general, good laboratory practices must be followed.

DCEs can be affected by changes in temperature, changes in the power supply voltage, EMC, interruption of weight 

data transmission media and possibly humidity depending on enclosure design. The manufacturer of the DCE under 

evaluation must also provide a compatible DWI element that will be used to indicate the output of the DCE. The 

following tests are appropriate for those DCEs that only digitize and transmit the weight information as well as those 

who also calibrate the weight signal and output the weight data in a calibrated format ready for display.

Purpose

The purpose of these tests is to determine the performance and operating characteristics of the DCE under test under 

loss of communication with the DWI element, at different ambient temperatures, and to determine the temperature 

effect on the no-load indication.

Pre-Test Conditions

3.1 Test Equipment Needed:

3.1.1 Environmental Chamber of sufficient capacity and temperature range

3.1.2 Load Cell Simulator

3.1.3 Calibrated Thermometer and Hygrometers

3.2 Device to be Tested

3.2.1 DCE

3.2.2 DWI Element

3.2.3 Interconnecting Cable (not required if interface is wireless)

3.3 Conditions of Equipment Under Test

3.3.1 The DCE shall be connected to the Load Cell Simulator following instructions provided 

in the manufacturer’s documentation. Connect the DCE to the DWI Element following 

the manufacturer’s instructions (unless a wireless interface is used). Connect the DCE 

and the DWI Element to a power source in accordance with the manufacturer’s 

instructions. If equipped with power switch(es), turn both the DWI Element and DCE on 

and allow them to remain on for a p eriod of time equal to or greater than the 

manufacturer’s recommendations.

3.3.2 Verify that the DCE and DWI Element are operational by observing the weight display in 

response to changes in the setting of the Load Cell Simulator.

3.3.3 Place the DCE and DWI Element within the environmental chamber and set the 

temperature to 20 °C (68 °F) or at the mid point of the temperature extremes if a 

temperature range other than the standard – 10 °C to 40 °C (14 °F to 104 °F) range is 

specified by the manufacturer.

3.3.4 Prior to beginning the test, verify that the ambient humidity does not exceed 50 % 

relative humidity and that the DCE and DWI Element are at thermal equilibrium.
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F25

3.4 Communications Interface Interruption

3.4.1 The purpose of this test is to ensure that no erroneous weight information is transmitted 

when the communications interface between the DCE and DWI Element is interrupted. 

Increase the setting of the Load Cell Simulator until a reading within the range of 500 to 

5000 divisions is displayed by the DWI Element. Record the reading. R emove the 

primary power from the DCE by unplugging its power cord or, if so equipped, remove 

the battery. If the DCE receives its power from the DWI, it will be necessary to contact 

the manufacturer to determine the method to be used to disconnect it from its source of 

power. Observe the DWI Element. T he weight value shown by the DWI Element 

should, within two seconds of interrupting communications, change to either a b lank 

display or error message. It should not be able to display, record, or transmit a weight 

value under these conditions. R estore power to the DCE. D oes the DWI Element 

indicate an error condition or blank display when the communications with the DCE is 

interrupted?

Yes No N/A 

3.4.2 Repeat the test described in 3.4.1 above but rather than disconnecting the DCE from its 

power source, disconnect the communications cable or block the wireless signal if so 

equipped. Does the DWI Element indicate an error condition or blank display when the 

communications with the DCE is interrupted?

Yes No N/A 

3.5 Effect of Temperature on Device Output

Code References: T.N.8.1

 

3.5.1 The purpose of this test is to determine the effect of changes in temperature on the output 

of the device. P lace the DCE and DWI Elements within the environmental chamber. 

Connect the Load Cell Simulator or Load Receiving Element to the DCE and place the 

Load Cell Simulator or Load Receiving Element outside of the environmental chamber. 

Apply power to the DCE and DWI Elements according to the manufacturer’s 

instructions. S et the environmental chamber to a temperature of 20 °C if the full 

temperature range is being used or to the mid point of the temperature extremes if a 

temperature range other than the standard –10 °C to 40 °C (14 °F to 104 °F) range is 

specified by the manufacturer. If equipped, set the humidity to a setting not greater than 

50 % relative humidity. Allow the chamber and equipment under test to reach thermal 

equilibrium. Verify that these conditions are maintained for a minimum of three hours.

3.5.2 Using the Load Cell Simulator or Load Receiving Element, conduct at least two 

increasing and two decreasing load tests with at least five different test loads. If the DCE 

contains calibration settings and transmits a calibrated weight to the DWI Element, the 

test points shall include the maximum test loads at each tolerance level. If the DCE does 

not transmit a calibrated weight value to the DWI Element, it is not necessary to include 

the maximum test load at each tolerance level. 

3.5.3 Record the following information at each test load:

a. Time and date

b. Temperature

c. Relative Humidity

d. Test Load (mV/V or micro-strain) (or weight if a Load Receiving Element is used)

e. Indication

f. Error

g. Performance Notes if appropriate
NTEP Committee 2013 Final Report

Appendix F –NTETC 2012 Weighing Sector Meeting Summary

NTEP - F26

3.5.4 Increase the temperature of the environmental chamber to the maximum temperature 

specified by the manufacturer not to exceed 40 °C (104 °F) and allow the device under 

test to stabilize for at least 3 hours. Stability is assumed to have been reached when the 

intended temperature is maintained within ± 1 °C (2 °F) for a period of 10 minutes. 

3.5.5 Record the change in zero, if any, zero if necessary and repeat steps 3.5.2 and 3.5.3.

3.5.6 Reduce the temperature to the minimum specified. After the temperature has stabilized 

according to the definition in 3.5.4, allow the device under test to stabilize for a minimum 

of 3 hours.

3.5.7 Record the change in zero, if any, zero if necessary and repeat steps 3.5.2 and 3.5.3.

3.5.8 Increase the temperature to the temperature used in step 3.5.1 and, after the temperature 

has stabilized, allow the device under test to stabilize for a minimum of 3 hours.

3.5.9 Record the change in zero, if any, zero if necessary and repeat steps 3.5.2 and 3.5.3.

3.5.10 Additional tests at other temperatures within the specified range of temperatures may be 

conducted if so desired.

3.5.11 If the DCE fails to meet tolerance requirements while conducting the tests in this section 

of the procedure, the manufacturer has the option of specifying a s maller temperature 

range. If the DCE failed at only the original specified minimum or maximum 

temperature, the device need only be tested at the new specified minimum or maximum 

temperature. I t is not required to re-test over the entire newly specified temperature 

range.

3.5.12 If the DCE fails to meet tolerance requirements while conducting the tests in this section 

of the procedure, the manufacturer may have the option to have the test data reanalyzed 

for a larger e-min and a smaller n-max. Reanalyzing the data is only appropriate if the 

data were collected in an expanded display resolution to a resolution of one tenth of the 

specified e-min or with error weights if a load-receiving element was used in place of the 

Load Cell Simulator.

3.5.13 Before the manufacturer requests a smaller e-min and/or a larger n-max based on the 

performance during an evaluation, they must submit documentation illustrating the 

changes made to the device or the manufacturing process, in order to improve the 

metrological performance of the device. NTEP will require the submission of additional 

devices for temperature testing.

3.5.14 Does the device under test perform over the specified temperature range within 

tolerance?

Yes No N/A 

3.6 Power Voltage Variations

Code References: T.N.8.3.1.

The purpose of varying the power supply voltage is to determine the performance and operating 

characteristics of the Digital Device Controller that is under test at different voltage levels required 

by T.N.8.3.1.

If the DCEs provided with an automatic zero tracking device, it may be in operation during the 

test, in which case the error at zero point shall be determined by recording the error at a test load 

several intervals above the zero tracking limits.
