NIST in the CFR: 

A Report on References to NIST (and NBS) Products and Services in the CFR 

Executive Summary 

Regulations promulgated by different federal government departments and agencies refer 

to various NIST (and NBS) products. These references can be found in the Code of 

Federal Regulations (CFR). This report examines the references to identify, categorize 

and analyze the various NIST/NBS products and services cited. Compiling this 

information, the report provides conclusions on the value of NIST products and services 

for regulatory purposes to other federal government agencies and, based on an analysis of 

the references, provides recommendations for follow-up actions. 

 v
NIST in CFR: 

A Report on 

References to NIST (and NBS) Products and Services in the 

Code of Federal Regulations 

1. Objective 

The purpose of this study is to: (1) identify and categorize explicit references to the 

National Institute of Standards and Technology (NIST) and its predecessor, the National 

Bureau of Standards (NBS), in the Code of Federal Regulations (CFR); (2) analyze the 

citations to NIST/NBS in order to highlight the value of NIST to the United States 

Government, industry and the public; and (3) help define NIST’s role in the nation’s 

measurement system (NMS). 

A first step in identifying unmet measurement needs is to determine the NIST products 

and services that other federal agencies identify through regulations in the Code of 

Federal Regulations. 

This study did not capture indirect CFR references to NIST/NBS products and services, 

such as any agency regulation that refers to a documentary standard developed by a 

standards development organization (SDO) which, in turn, refers to a NIST/NBS product 

such as a Standard Reference Material or calibration service. Similarly, administrative 

references to NIST, such as authorization to create programs, are not included in this 

report. 

2. The Nation’s Measurement System 

The National Institute of Standards and Technology is presently evaluating its role in the 

nation’s measurement system (NMS). NIST developed a White Paper for internal 

discussion which includes a working definition of the NMS as “the complex of all 

methods, instruments, entities, institutions, and standards that support measurements of 

products and processes of national significance to the economy, quality of life, or security 

of the nation, where measurement is the process of quantitatively comparing a variable 

characteristic, property, or attribute of a substance, object, or system to norm”1

. The 

White Paper also lists a number of potential roles for NIST, concluding that NIST should 

take the lead in: 

• Identifying unmet measurement needs of U.S. industry, commerce, regulatory 

agencies, and national defense 

• Identifying needed de-facto national standards of measurement 

• Initiating collaborations with and among government agencies and industrial 

institutions with unmet measurements needs and responding appropriately

• Developing or collaborating with others on developing measurements, methods 

and standards to fill identified national measurement needs 

• Supporting other government agencies with special measurement needs 

3. The Code of Federal Regulations 

As a compilation of permanent rules and regulations adopted by all executive 

departments and agencies of the United States Government, the Code of Federal 

Regulations (CFR) is the single resource for finding the complete listing of U.S federal 

government rules and regulations, as well as their administrative scope. The CFR differs 

from the Federal Register in that the latter, published daily, officially announces proposed 

and final rules, notices issued by Federal agencies and organizations, as well as executive 

orders and other presidential documents. 

The CFR is organized in 50 titles, subdivided into chapters, parts, subparts and sections. 

Each title represents a broad area subject to federal regulation. In general, each chapter in 

the CFR provides the rules and regulations issued by a given agency, and each part in the 

chapter contains information pertaining to a single regulatory program. All titles are 

updated yearly in order to keep CFR information current. Hard copies of the CFR, 

published by the National Archives and Records Administration (NARA), can be 

purchased from the Government Printing Office; an electronic version is available 

without charge on-line at http://www.gpoaccess.gov/cfr/index.html and at 

http://www.gpoaccess.gov/ecfr. Certain chapters or texts thereof may be available on one 

website and not on the other. 

4. National Institute of Standards and Technology 

The mission of the National Institute of Standards and Technology (NIST), a nonregulatory federal agency within the U.S. Commerce Department's Technology 

Administration, is to develop and promote measurement, standards, and technology to 

enhance productivity, facilitate trade, and improve the quality of life. Founded in 1901 as 

the National Bureau of Standards (NBS), its name was changed to the National Institute 

of Standards and Technology and its mission was expanded under provisions of the 

Omnibus Trade and Competitiveness Act of 1988. NIST is the national metrology 

institute (NMI) of the United States, with core activities in metrology, measurement 

science, measurement services, and support for documentary standards. NIST offers 

numerous measurement- and metrology-related products and services that are used, 

adopted and/or mandated by other U.S. Government agencies and industry. For example, 

federal agency mandates in the Code of Federal Regulations include : (a) the use of NIST 

Standard Reference Materials (SRM) for calibration of equipment used in testing; (b) that 

equipment be calibrated through calibration services offered by NIST; (c) traceability to 

national physical standards realized by NIST; (d) accreditation of testing laboratories by 

the National Voluntary Laboratory Accreditation Program (NVLAP), administered by 

NIST; and (e) the use of weights and measures handbooks developed by NIST. 

Appendix 1 
5. NIST in CFR Studies and Data 

5.1. Previous studies 

Two previous studies identified and compiled NIST/NBS references using two different 

approaches. In the first study, Martinez and DeVaux2, searched the CFR to identify 

references to NIST/NBS and identified them with the keywords listed in Appendix 1. 

Martinez and DeVaux concluded that approximately 30 agencies reference NIST and/or 

NBS products or services, with citations falling into 4 broad categories: (a) references to 

NIST Handbooks; (b) references to other NIST/NBS publications; (c) references to 

NIST/NVLAP accreditation; and (d) references to traceability/calibration to NIST 

standards and to SRMs. Those authors also identified erroneous practices and misuse of 

terminology, such as: (a) interchangeable and incorrect use of the terms ‘traceability’ and 

‘calibration’; (b) references to documents from the 1950s, 60s and 70s, that are no longer 

valid, not available, or perhaps withdrawn; (c) references to NBS instead of the correct 

current name, NIST, and some references to both NBS and NIST in the same paragraph. 

Martinez and DeVaux identified a total of 240 citations. Those references, organized by 

federal agency, are summarized in Appendix 2. 

In the second study, Aanstoos3 used a commercial internet-based search engine (LexisNexis Congressional Index) to search for references to NIST and NBS in electronic 

versions of the CFR (Appendix 3) and in the regulatory indices of California and Texas. 

He found 519 citations, but due to the nature of the search algorithm, many references 

were of an administrative nature; others were references that have been deleted or 

replaced, but still listed under their original citation. These results, organized by the 

number of citations per title, are provided in Appendix 4. 

5.2. Data used for this study

References from the two studies cited above were combined to create an initial data set 

for the current study. The authors reviewed and eliminated from the combined data set 

any duplicated references, references that were administrative in nature, and references 

that have been deleted or replaced. 

Table 1 summarizes the resulting data set, listing the title where the reference is found, 

the department or agency referring to NIST/NBS, and the number of references. After 

comparison and review, a total of 376 references to NIST/NBS products and services 

were identified. To facilitate accessing specific information, readers may consult 

Appendices 5 through 21 which provide information sorted by product or service. The 

full listing is presented, by CFR title, in Appendix 22.

Appendix 1 
On review of the references and their context, the authors of this study classified the 

NIST/NBS products and services broadly identified in the CFR as: 

(a) references related to traceability and calibration; 

(b) Standard Reference Materials (SRM); 

(c) NBS/NIST Special Publications; 

(d) assorted publications; 

(e) weights and measures handbooks; 

(f) references to the National Voluntary Laboratory Accreditation Program (NVLAP) and 

the National Voluntary Conformity Assessment System Evaluation Program (NVCASE); 

(g) Voluntary Product Standards (VPS) and Commercial Standards (CS); 

(h) computer security; 

(i) Circular 484; 

(j) other handbooks; and 

(k) the National Technology Transfer and Advancement Act (NTTAA). 

Table 2 lists the number of references in each category in order of the number of times 

each product/service is cited. The majority of references are related to traceability and 

calibration services. It is important to note that some citations may be construed to refer 

to more than one NIST product or service; the authors of this study chose to classify 

those ambiguous references in what was judged the most important and pertinent 

category. For example, a citation requiring the use of SRM for calibration of an 

analytical instrument to ensure traceability to a NIST standard would be listed under the 

SRM category, rather than under traceability or calibration.

Appendices 5 through 21 provide a complete listing of references as classified in the 

categories indicated above. The compiled list of all references can be seen in Appendix 

22. The following section is a detailed analysis of these references. 

6. Analysis of NIST in CFR references 

This section provides an overview of the citations by category. 

6.1. Traceability and Calibration 

A majority of the citations to NIST in the CFR are to NIST/NBS products and services 

for establishing traceability or for calibration services. Appendix 5 indicates 188 

references within this category, distributed among 10 departments/agencies, with 158 

references by the EPA alone. 

The scope of the references to NIST traceability and calibration services varies broadly 

among agencies. USDA/GIPSA refers to the NBS program for the Certification of 

Capability of State Measurement Laboratories regarding approval by the Grain Inspection, 

Packers and Stockyard Administration as qualified metrology labs and Type Evaluation 

Laboratories. The CPSC generically cites the NBS calibration service as a requirement 

for calibrating total flux meters used to measure critical radiant flux. The FDA requires 

microphone calibration to be traceable to the NBS as a requirement for audiometer 

calibration set for use with diagnostic devices, particularly Ear, Nose and Throat devices. 

Under the Mammography Quality Standards Act, the FDA defines an instrument being 

“traceable to a national standard” if it is calibrated either at NIST or at a calibration 

laboratory that participates in a proficiency program with NIST. HUD requires that each 

laboratory “provide a description of the applicable standards and calibration equipment 

being used and the calibration procedures followed, including National Bureau of 

Standards traceability, when applicable”. The Bureau of Indian Affairs requires that all 

weights and measures shall “conform to standards set by the National Bureau of 

Standards and to standards, if any, set by the tribe and, if not in conflict with tribal 

regulations, to the standards set by the State". 

OSHA mandates the use of the NBS 9A coupler for acoustic calibration of audiometers. 

It requires that test equipment for gear certification be tested for accuracy using 

calibration equipment whose “indications are traceable to the National Bureau of 

Standards”. As part of the quality assurance requirements for testing by third party or 

applicants, instruments used for the inspection and testing of critical characteristics must 

be calibrated at least as frequently as, and according to, the instrument manufacturer's 

specifications, “using calibration standards traceable to those set by the National Bureau 

of Standards”. For test equipment requirements of diesel engines intended for use in 

Appendix 1 
underground coal mines, MSHA requires span gas and calibration gas values to be 

traceable to NIST SRMs. Similarly, MSHA requires that light measuring instruments 

shall be calibrated against standards traceable to the National Bureau of Standards. The 

U.S. Coast Guard requires that inspection, testing and retesting of deck coverings, 

structural insulation and bulkhead panels for merchant vessels be conducted at NBS or 

other laboratories designated by the Coast Guard. The FCC, in its regulations applicable 

to all broadcast stations for carrier frequency measurements, stipulates that “the primary 

standard of frequency for radio frequency measurements is the standard frequency 

maintained by the National Bureau of Standards or the standard signals of Stations WWV, 

WWVB, and WWVH of the National Bureau of Standards". 

EPA references NIST/NBS traceability and calibration products over a broad spectrum of 

applications. Under the general provisions of the Air Program’s Ambient Air Quality 

Surveillance, EPA defines traceable as “a local standard that has been compared and 

certified, either directly, or via not more than one intermediate standard, to a National 

Institute of Standards and Technology (NIST)-certified primary standard such as a NISTTraceable Reference Material (NTRM) or a NIST-certified Gas Manufacturer’s 

Intermediate Standard (GMIS)”. EPA also refers to NIST to define a NIST-EPA 

approved Certified Reference Material, Research Gas Material, and Research Gas 

Mixture. Repeated references to these products indicate their importance in satisfying a 

critical requirement for the EPA. Calibration and span gases must be compared with 

NIST gas standards (with traceability) to ensure that the analytical gases used for testing 

or calibrating the test equipment meet accuracy and purity specifications. EPA defines a 

stock solution as one that is made with a reference material traceable to NIST. Some 

references require the traceability to specific standards, as in the National Primary and 

Secondary Ambient Air Quality Standards, requiring that the gases used in calibration 

procedures be traceable to a NBS carbon monoxide-in-air SRM. Other references are 

more general, as in the inspection/maintenance program requirements of Air Programs, 

which state that “span and zero gases should be traceable to National Bureau of Standards 

reference gases” whenever these reference gases are available. Similarly, other 

regulations require flow calibration devices to be traceable to NIST to ensure accuracy of 

the devices (Continuous Emissions Monitoring Program, Air Pollution Controls). 

In addition to requiring traceability of gases to NIST standards, EPA regulations also 

require traceability of calibration weights to NIST standards, which are used for 

calibrating torque measuring devices. Under the National Emission Standards for 

Hazardous Air Pollutants for Source Categories Program, numerous citations require 

reference temperature monitors to be traceable to NIST standards used in sterilization 

facilities. Under the Primary and Secondary Ambient Air Quality Standards, EPA 

requires both traceability to NIST for measuring instruments, and the use of standards 

that are traceable to NBS SRMs or an NBS/EPA-approved commercially available 

Certified Reference Material (CRM). 

Under the Air Quality Programs, through the Standards for Performance for New 

Stationary Sources, EPA requires that spectrophotometers have a NIST-traceable 

calibration as a minimum design specification, and in the case of the Fourier Transform 

Appendix 1 
Infra-Red Spectrometers (FT-IR), the performance specifications require the use of 

gaseous audit samples comprised of components whose concentrations are traceable to 

NIST standards. Similarly, regulations covering continuous emissions monitoring require 

the use of reference values from NIST traceable equipment, and regulations covering the 

Acid Rain Program require certificates showing traceability to NIST protocols and other 

supporting documents. EPA regulations also require that equipment used in dew point 

measurements be traceable to NIST standards and that certification and calibration for 

microbalances be NIST traceable. Extensive references to NIST products and services are 

also found in Emission Regulations for New Otto-Cycle and Diesel Heavy-Duty Engines; 

Gaseous and Exhaust Test Procedures. 

‘NIST True Value’ for purposes of torque calibration is defined by EPA as “the torque 

calculated by taking the product of a NIST traceable weight or force and a sufficiently 

horizontal distance along a lever arm, corrected for the lever arm’s hanging torque”(Air 

Pollution Control Programs). However, true value, in general, is defined by NIST as the 

value consistent with the definition of a given quantity, i.e., a value that would be 

obtained by a perfect measurement, and hence by nature is indeterminate4

. Thus while 

NIST recognizes a “true value” to be indeterminate, a NIST traceable value is referred to 

by EPA as the “NIST true value”. This inconsistency is further compounded by EPA’s 

definition of the term ‘accuracy’ as “the maximum difference between a measured or 

calculated value and the true value, where the true value is determined by NIST” (40 

CFR 1065.1001). A different approach to the question of NBS true value is seen in the 

Emission Regulations for New Otto-Cycle and Diesel Heavy-Duty Engines; Gaseous 

And Particulate Exhaust Test Procedures, where the regulations require that flowmeter 

calibration be traceable to NBS, and further specify that value to serve as the reference 

value (i.e., the NBS true value). In addition, the EPA test procedure and equipment 

requirement under the Air Pollution Control Program which exempts the need for 

approvals to be sought for using international calibration standards if the “standards have 

been shown to be traceable to NIST standards”.

6.2. Standard Reference Materials (SRMs) 

Standard Reference Materials (SRMs) are referred to in the CFR by DoL/OSHA, the 

EPA, and DoT/NHTSA (Appendix 6). The citations are either to specific SRMs or to 

SRMs in general. A specific citation is the reference to SRM 2670 by DoL/OSHA as a 

possible source of reference materials available for use in Quality Control/Quality 

Assurance (QC/QA) analyses of cadmium in urine under the Occupational Safety and 

Health Standards for Hazardous and Toxic Technology. As a generic citation, EPA 

refers to SRMs as a source of calibration gases that can be used to meet the specifications 

and test procedures for continuous emissions monitoring. 

DoT/NHTSA, as part of its regulations for Federal Motor Vehicle Safety Standards for 

motor vehicle brake fluids, requires the use of zinc oxide, oil furnace back and sulfur 

used in the formulation of rubber compound for making styrene-butadiene rubber brake 

cups for testing motor vehicle brake fluids. The standard stipulates the concentration of 

 

4

 J. Randa, NIST Project on Standard Terminology for Microwave Radiometry (2002), page 6. 

Appendix 1 
components used for making the brake cups, and requires that zinc oxide, oil furnace 

black and sulfur used in such formulations have properties identical to NBS 370 (zinc 

oxide), NBS 378 (oil furnace black) and NBS 371 (sulfur) as materials supplied by the 

National Bureau of Standards. These materials are not currently listed in NIST databases 

and are not available from NIST. 

HHS/FDA cites NBS Material 577 as part of the test for compliance that food additive 

combustion product gas may be safely used in the processing and packaging of the foods, 

using spectrophotometric measurements. However, this reference material, too, is not 

available from NIST. 

EPA depends substantially on several NIST products and services for the enforcement of 

its regulations. EPA’s Air Programs and the Toxic Substances Control Act refer 

extensively to NBS and NIST Standard Reference Materials to be used in calibrating 

devices that must show traceability to NIST. The EPA defines traceability as a “local 

standard that has been compared and certified either directly or via not more that one 

intermediate standard, to a primary standard such as a National Bureau of Standards 

Standard Reference Material (NBS SRM) or a USEPA/NBS-approved Certified 

Reference Material (CRM)”. Under the National Primary and Secondary Ambient Air 

Quality Standards, permeation devices used for determination of sulfur dioxide in the 

atmosphere should be traceable to SRMs 1625, 1626 and 1627, and similarly calibration 

procedures for the measurement of nitrogen oxide and nitrogen dioxide (NOx gases) 

requires that permeation devices must be calibrated with a reference standard that is 

traceable to SRM 1683 or SRM 1684 (for NO) and SRM 1629 for NO2. 

EPA also cites SRM 930D related to spectrophotometer calibration and the use of NBS 

SRM 1876 and RM 8410 as a measure of accuracy and comparability in Transmission 

Electron Microscopy for asbestos-related analyses. 

NIST SRMs form the basis for EPA’s definition of Standard Reference Materialequivalent compressed gas primary reference material (SRM-equivalent PRM). 

Furthermore, EPA requires that working and transfer standards and equipment used for 

auditing must be different from the standards and equipment used for calibration and 

spanning, but may still refer to the same NIST SRM, CRM, etc. 

References to NIST standards are also found in EPA procedures related to gaseous 

exhaust test methods for emissions regulation, and for gasoline-fueled and diesel-fueled 

heavy duty engines, where SRMs are used as calibration and span gases, or where the 

gases used for such purposes must be derived from NBS SRMs. Similar requirements are 

also included in emission test equipment provisions for control of emissions from nonroad spark-ignition engines at or below 19 kW. 

SRM 1627 and 1629 are not listed in the NIST SRM database. SRMs 1625, 1626, 1683 

and 1684 are listed, but are flagged as being “out of stock”. SRM 1876 was superseded 

by 1876b, which also is out of stock. There is no information on RM 8410, but RM 8411 

is listed as being out of stock. NBS 370, 371, 372, 378, 384 and 577 are either out of 

Appendix 1 
stock or not listed. SRM 930D is available as SRM 930e and SRM 1582 as well as SRM 

2670 are available. Out of 18 specifically numbered SRMs cited, only 3 are available.

6.3. Special Publications 

DoL/OSHA cites once the 1977 NBS publication on polarized light microscopy of 

asbestos. 

EPA has a total of four citations of NBS Special Publications: three to the 1978 NBS 

SP506 on misidentification of asbestos in talc, and two to the 1976 NBS SP 442 on 

organic chemical analysis for municipal and industrial wastewater. 

The DHS/USCG has 20 references to the 1976 NBS Special Publication 440, a dictionary 

of color names. 

Two copies of SP 506 are available at NIST. There is a holding related to SP442 which 

is a 1983 supplement to the Manual on Water, sponsored by ASTM Committee D19. 

Two copies of SP 440 are available at NIST. 

Appendix 7 shows the references to Special Publications. 

6.4. Assorted Publications 

A wide variety of NBS/NIST publications are grouped in this category. 

The DoE, part on energy management and planning programs, cites a NIST 1985 

publication on life cycle costing. 

FTC cites three times a 1995 NIST publication on testing of engine oil, making its 

requirements mandatory. 

FERC cites once a 1984 NBS publication on seismic review of liquid natural gas 

facilities. 

Appendix 1 
HUD cites once for its minimum property standards a 1970 NBS publication on the 

flammability testing of textile floor coverings. The test method is also available as an 

ASTM standard. 

DoL/OSHA cites five NBS publications from 1980-1983 that help understand some 

requirements for accident prevention signs and tags. With the same purpose, there is a 

citation for 1978 NBS publication on fire alarms and communication systems. 

Two undated NBS reports are cited by OSHA as a source of definitions in classifying 

soils and rocks deposits and for shoring and sloping of trenches and excavations. 

EPA has five citations to three NBS documents. The first is to an undated report on 

standard reference powder refraction patterns; two are to a 1986 report on the aqueous 

solubility of organic compounds; and two are for the 1981 report on the same subject. 

USCG has nine references to three publications. The 1956 NBS Report 4792 on a test to 

evaluate smoke signals is cited five times. An undated NBS Simplified Practice on first 

aid kits is cited three times. One citation refers to an undated NBS report on tests on fire 

extinguishers. 

FCC cites three times a 1967 NBS technical note on calculating the PCS signal levels at 

microwave receivers. 

These references are listed in Appendix 8. 

6.5. Weights and Measures Handbooks (Handbook 44, 105-1 and 133). 

Handbook 44, a NIST publication that provides specifications, tolerances and other 

technical requirements for weighing and measuring devices, is referenced 15 times in the 

CFR, mostly by the Department of Agriculture in both titles 7 and 9. FDA and EPA also 

cite this handbook. In title 7, there is one reference in the Agricultural Marketing Service 

chapter, under part 58 for dairy plants and products, and two references in the Food Grain 

Inspection Service chapter, parts 801 and 802 on weighing equipment. In title 9, there is 

one reference in part 201 for the regulations under the Packers and Stockyards Act, four 

references in the Food Safety and Inspection Service chapter, part 317 on labeling and 

marking and three additional references in part 381 on poultry products. 

FDA cites Handbook 44 three times under part 1 on general enforcement regulations, and 

EPA cites it once in part 63 on emissions standards for monitoring requirements. 

Handbook 44 is published yearly, and has been issued 25 times since 1979. It is available 

in hard copy and on-line from the NIST Weights and Measures Division web site at 

http://ts.nist.gov/ts/htdocs/230/235/pubs.htm. 

Handbook 133, a NIST publication on checking the net contents of packaged goods, is 

referenced six times by the USDA/FSIS in its part 317 on labeling and marking and in 

Appendix 1 
part 381 on poultry inspection regulations and subpart on procedures for net weight 

compliance. Two of the USDA citations make the Third Edition of Handbook 133 

mandatory; the other four exclude specific chapters of Handbook 133 that are irrelevant 

to USDA regulations. 

Handbook 133 has been published in four editions. The most recent is the January 2005 

version of the 4th Edition that was published in 2004 and is available at 

http://ts.nist.gov/ts/htdocs/230/235/pubs.htm . The 1988 version referenced in the CFR is 

available for review at the Weights and Measures Division of NIST. 

Handbook 105-1, a 1990 NIST publication on the specifications and tolerances for 

reference standard and field standard weight and measures (NIST Class F), is referenced 

once by the USDA’s Grain Inspection, Packers and Stockyards Inspection (Federal Grain 

Inspection Service) and is incorporated by reference. 

Handbook 105-1 is available from the NIST Weights and Measures Division web site and 

can be downloaded at http://ts.nist.gov/ts/htdocs/230/235/labmetrologypage.htm

References to Handbooks 44, 105-1 and 133 and their complete titles are included in 

Appendix 9. 

6.6. Accreditation, the National Voluntary Laboratory Accreditation Program 

(NVLAP), and, the National Voluntary Conformity Assessment System Evaluation 

(NVCASE) 

One reference under the DoE’s part 431 for the energy efficiency of certain commercial 

and industrial products cites NVLAP. 

Two references under the title 15 chapter on NIST, part 280 pertain to the Fastener 

Quality Act. 

HUD has three citations to NVLAP in part 200 on FHA (Federal Housing 

Administration) programs. The first reference states that its building product certification 

requirements may require accreditation of laboratories by programs such as NVLAP. 

The second and third refer to periodic carpet testing in a NVLAP-accredited laboratory. 

DoL/OSHA cites NVLAP once in its part on asbestos to require testing in a ‘nationally 

recognized testing program’ such as a NVLAP-accredited laboratory. 

EPA cites NBS-accredited laboratories for testing asbestos for school programs. 

FCC cites NIST and NIST programs seven times. Three references are in part 2, subpart 

on equipment authorization procedures, in the sections on designation and on 

authorization of Telecommunications Certification Bodies (TCB). The other four are in 

part 68 on connections of terminal equipment to the telephone network, subparts on 

conditions on use of terminal equipment, sections on the designation and requirements 

Appendix 1 
for telecommunications certification bodies (TCBs). The NVCASE program, NIST 

roles, and the NIST accreditation program are recognized. However, NVLAP is not 

specifically mentioned; rather the reference is to accreditation under the NVCASE 

program. 

These references to NVLAP and NVCASE are shown in Appendix 10.

6.7. Voluntary Product Standards and Commercial Standards 

NIST is an active participant in standards development, but, in general, does not develop 

standards. Two exemptions to this are the development of Computer Security 

Guidelines/standards for use by the federal government (known as Federal Information 

Processing Standards) and the development of certain Voluntary Product Standards 

(VPS). The Department of Commerce is authorized to sponsor voluntary Product 

Standards development through 15 CFR 10 (b), which defines the requirements for DoC 

to sponsor Voluntary Product Standards development, and also defines the role of DoC in 

such a process, granting NIST the authority to administer these procedures for the 

department. 

VPS 36-70 and VPS 54-72 define apparel sizes for boys and girls, respectively. They are 

cited by the CPSC in defining tight-fitting with respect to the flammability of children’s 

sleepwear. However, these standards are no longer valid. Paper copies are available at 

the National Center for Standards and Certification Information (NCSCI) at NIST. 

HHS/FDA, in the part on animal food labeling, makes a general reference that if a NBS 

voluntary product standard exists for the number of servings, any label under FDA 

regulation shall use it.

 

HUD has eight citations to the following standards in the HUD Minimum Property 

Standards. PS 1-83 relates to construction and industrial plywood and PS 2-92 gives 

performance requirements for wood-based structural panels. VPS 20-94 provides 

requirements on grade marking and is cited once by HUD. CS 136-55 is on insect wire 

screening and CS 242-62 relates to steel doors and frames. 

PS 1-83 is no longer valid and has been superseded by PS 1-95. VPS 20-94 is no longer 

valid and has been replaced by PS 2-92 and PS 20-99. The current versions are available 

electronically at the NIST/TS web site http://ts.nist.gov/ts/htdocs/210/sccg/sccg.htm. CS 

136-55 and CS 242-62 are no longer valid. Paper copies of withdrawn standards are 

available at NIST/NCSCI. 

DoL/OSHA cites CS 202-56 on industrial lifts and loading ramps once. However, CS 

202-56 has been withdrawn and is no longer valid. Paper copies are available at 

NIST/NCSCI. 

 The references to these standards are shown in Appendix 11. 

Appendix 1 
6.8. Computer Security

The Office of Personnel Management makes two references to NIST on computer 

security. The first is to NIST Special Publication 500-172 on computer security training 

guidelines, and the second is a general reference to NBS standards on the physical 

security of automated data processing. SP500-172 has been cancelled. 

FERC in a general fashion cites once the NBS guidelines on computer security. 

Under the Foreign Relations title of the CFR, in the chapter on International Boundary 

and Water Commission, US and Mexico Section, the part on the Privacy Act of 1974 

there is a citation to the NBS booklet on “Computer Security Guidelines for 

implementing the Privacy Act of 1974”. 

Under the Bureau of Indian Affairs title of the CFR, in the chapter on the Navajo and 

Hopi Indian Relocation, part on Commission Operations and Relocation Procedures, 

subpart on Privacy Act, there is reference to the NBS booklet on computer security 

guidelines. 

Under the Judicial Administration title of the CFR, in the chapter on the Office of the 

Independent Counsel, part on the production or disclosure of material or information, 

there is a reference to consistency with the guidelines developed by NBS for the security 

of systems of records. 

Under the Treasury title of the CFR, there is a reference to the standards promulgated by 

NBS to ensure maintenance of records under the Privacy Act. 

Under the Public Contracts and Property Management title of the CFR, in the chapter on 

temporary duty travel allowances, part on agency travel accountability requirements, 

there is reference to the NIST security and privacy requirements for electronic data 

exchange. 

Under the Interior title of the CFR, in the part on records and testimony, subchapter on 

the Privacy Act, there is reference to the NBS booklet on computer security guidelines. 

HHS in the chapter on child support enforcement, part on standards for program 

operations, both Subpart 7 on provisions of services in interstate cases and Subpart 72 on 

collection of past-due support by Federal tax refund offset refer to the NIST Federal 

Information Processing Standards (FIPS) publication. While a specific reference is not 

mentioned, it may be presumed that it is FIPS Pub 55-DC3 which is available at 

http://www.its.nist.gov/fipspubs/fip55-3.htm. 

Under the Transportation title of the CFR, chapter on the Federal Motor Carrier Safety 

Administration, part relevant to the hours of service of drivers, the NBS FIPS publication 

1-1 is cited for the automatic on-board recording devices. No reference to NIST FIPS 

Pub 1-1 has been found in the NIST FIPS archives. 

Several agencies cite computer security guidelines to implement the 1974 Privacy Act. 

FIPS Pub 41, which provides these guidelines and is presumably the text referred to by 

Appendix 1 
the agencies, was withdrawn in 1998. It is still however available at 

http://www.itl.nist.gov/fipspubs/fips41.pdf

 

 

Appendix 12 provides these references. 

6.9. Circular 484, a 1949 NBS publication on spectrophotometry, is cited three times by 

the HHS/FDA in part 172 on permitted food additives, in the sections on petroleum 

naphtha, on synthetic fatty alcohols and on petroleum wax. It is cited four times in part 

178 on indirect food additives, twice in the section on mineral oils, once in the section on 

polyhydric alcohol esters of oxidatively refined (Gersthofen process) montan wax acids 

and once in the section on surface lubricants used in the manufacture of metallic articles. 

Circular 484 was published only in 1949; one copy is available at NIST. 

References to Circular 484 are in Appendix 13. 

6.10. Handbook 69 is a 1959 NBS publication on the determination of radiation 

exposure; four agencies reference it. The NRC references it in the subpart for reactor site 

criteria and in the subpart for licensing of productions and utilization facilities - technical 

information. The DoL/WHD cites this handbook under its part on child labor 

regulations, subpart on occupations particularly hazardous to minors. Both EPA 

references are in part 141 on national primary drinking water regulations, one under 

definitions and the other under the maximum contaminant levels and maximum residual 

disinfectant levels. The DoD refers to Handbook 69 in part 650 on environmental 

protection and enhancement, subpart on hazardous and toxic materials management. 

Handbook 69 was originally published in 1959. Contrary to the EPA citation, the NIST 

library information does not indicate any 1963 revision. One copy is available at NIST. 

References to Handbook 69 are included in Appendix 14. 

6.11. Handbook 28, a 1957 NBS publication on screw thread standards, is referenced 

once by CPSC in relation to attachment hardware for bicycles. It is referenced four times 

by the DoT/RSPA, once in a general information subpart, twice in the subpart on 

specifications for packaging used for the transportation of hazardous materials, and once 

in the subpart for tank cars. 

Handbook 28 was originally published in 1939, and then republished in 1942, 1944 with 

supplements, 1949, and 1950. In 1957, it was issued in three parts, and in 1963 it was 

republished with one supplement. Seven copies are currently available at NIST. 

The CFR references to Handbook 28 are shown in Appendix 15. 

Appendix 1 
6.12. Handbook 81, a 1961 NBS publication on safety rules for the installation of 

electrical supply lines, is referenced three times by the DoL/MSHA, under safety and 

health standards, in its part 56 on surface metal and nonmetal mines and in its part 57 on 

underground metal and nonmetal mines and for part 77 on surface coal mines and surface 

work areas of underground coal mines. The subpart on surface high-voltage distribution 

references the National Electrical Safety Code, which was formerly (?) Handbook 81. 

Handbook 81 was originally published in 1941 and then updated in 1961. Both versions 

were approved by the American Standards Association (the predecessor of the American 

National Standards Institute, ANSI). Contrary to the MSHA citation, the NIST library 

information does not indicate any 1968 supplement. One copy is available at NIST. 

References to Handbook 81 are provided in Appendix 16. 

6.13. National Technology Transfer and Advancement Act (NTTAA)

There are three citations in the CFR to the NTTAA, which defines the responsibilities of 

NIST, those of federal agencies, and those of Agency Standards Executives with respect 

to the Act. 

Appendix 17 lists the references. 

6.14. Handbook 91, a 1966 NBS publication on experimental statistics, is referenced 

twice by the DHS/USCG, part 162 on engineering equipment, subpart on pollution 

prevention equipment; once as a document incorporated by reference; and once under 

designation of a facility authorized to perform approval tests. 

Handbook 91 was originally published in 1963 and republished with corrections in 1966. 

Three copies of the 1963 version and five copies of the 1966 version are available at 

NIST. An updated and expanded version of this handbook is now available as the 

NIST/SEMATECH e-Handbook of Statistical Methods, 

http://www.itl.nist.gov/div898/handbook/. 

CFR references to Handbook 91 are in Appendix 18. 

6.15. Handbook 96, a 1964 NBS publication on inspection of photographic record films 

for blemishes due to aging, is referenced twice by the DoT. The first reference is by the 

Maritime Administration in its part 380 on procedures, subpart on records retention 

schedule. The second is by the Federal Motor Carrier Safety Administration, part 390 on 

general requirements and information, section on copies of records or documents. 

Handbook 96 was published only in 1964; one copy is available at NIST. 

Appendix 1 
References to Handbook 96 are shown in Appendix 19. 

6.16. Handbook 150 and its several supplements provide the procedures and 

requirements for the NVLAP. Handbook 150-01 is referenced under the DoE’s part 430 

on the energy conservation program for consumer products program and in part 431 on 

the energy efficiency program for certain commercial and industrial products under 

testing laboratories. 

Handbook 150 and all its supplements are available for free downloading from the 

NIST/NVLAP web site at http://ts.nist.gov/ts/htdocs/210/214/214.htm. 

References to Handbook 150 are included in Appendix 20.

6.17. Handbook 136, a 1981 publication on radiological safety, is also identified as an 

American National Standard, ANS N432. It is referenced once by the DoE/NRC, in part 

34 on licenses for industrial radiographic operations as a mandatory requirement for 

equipment performance. 

Handbook 136 was published only in 1981; at least one copy is available at NIST. 

References to Handbook 136 are listed in Appendix 21. 

7. Availability of NIST Products cited in the CFR 

Information on the availability of SRMs is provided in Table 3 in section 6.2 above. 

Information on the availability of NIST/NBS publications is provided in Appendix 23. 

8. Conclusions 

From the range of references, it is obvious that U.S. federal agencies have looked, and 

continue to look, to NIST to provide measurement leadership, along with state-of-the-art 

products and services for metrology, measurement, laboratory accreditation, conformity 

assessment and for information technology security. The longevity of some of the 

identified references clearly indicates NIST’s long-standing and essential role 

measurement science and expertise. Furthermore, the multiple references to numerous 

NIST products and services attest to their inherent value for many government programs. 

Thus, it is evident from the extent of the NIST citations in the CFR that U.S. federal 

agencies rely upon and value highly NIST metrology and measurements expertise. Some 

important examples include gas standards for use as calibration and span gases and 

references to NIST Handbook 44. 

It should be emphasized that this study did not attempt to measure the impact of specific 

NIST/NBS products and services or their totality on the U.S. economy. However, NIST 

impact on the U.S. economy and society is evident through the numerous references by 

Appendix 1 
U.S. federal agencies to particular NIST products and services. One example is the 

traceability requirements that EPA includes in their regulations for stationary source, 

mobile source and ambient air monitoring which has led to a strong demand for NIST 

SRMs and certification of NIST Traceable Reference Materials (NTRM). To increase the 

availability of certified gas-mixture reference materials, NIST in collaboration with the 

EPA and the appropriate specialty gas companies, created the NTRM program. This 

program has been projected to have net benefits between $ 49 million and $ 63 million 

from 1990 through 2007, at 2001 dollar value5. Another clear example of NIST impact is 

in EPA regulations that refer to NIST SRMs within the context of measuring the sulfur 

content of fossil fuels. The economic impact of these SRMs, including benefits accruing 

from improvement in product quality, production efficiency, and reductions in transaction 

costs and sulfur dioxide emissions to the environment have been estimated at $409 

million, beginning in 1984 and projected through 2003, at 1998 dollar value 6. 

There is a wide range of U.S. federal agencies with regulations requiring compliance with 

NIST guidelines/standards on computer and data security. An economic impact 

assessment of NIST’s Data Encryption Standards program has estimated the impact to be 

between $345 million and $1.19 billion (net present value in 2000)7. It is important to 

note that these estimates are for the overall use of NIST’s data encryption standards, and 

include the effect due to federal regulation requirements. 

Federal regulations require thermocouple calibration or traceability to NIST. One way to 

meet this requirement is through the NIST Thermocouple Calibration Program (TCP). 

An economic impact study of this program found that the internal rate of return from the 

TCP investments is at least 31.8 %8. The study also concluded that this rate of return 

indicates a socially-valuable activity affecting a broad range of U.S. domestic industries. 

 

The most significant impact of NIST product and services on the U.S. economy is 

illustrated by the Weights and Measures Handbooks (Handbooks 44, 105-1 and 133) 

which are cited twenty two times by five agencies (most often USDA). It has been 

estimated that weights & measures regulations impact $4.5 trillion of commerce or 52% 

of the U.S. GDP in 1998 figures. In addition, virtually all states’ regulations reference 

NIST weights and measures handbooks. This also illustrates that a simple numeric count 

of citations is not an adequate indication to assess the critical importance and/or impact of 

NIST products. 

In general, while numerous references to NIST products, services and publications in the 

CFR are valid, there are also a number of inaccurate, erroneous, and outdated references. 

In some instances there are NIST products and services which are cited but not available,

Appendix 1 
and in some instances there is no information at NIST about them. Examples are the 

NIST SRMs that are out of stock, and the references in the CFR to NBS Materials for 

which there is no available information. 

The methodical review of the CFR conducted presents an opportunity for NIST regarding 

its products and services. NIST should make every effort to assure that up-to-date 

services are known and available to U.S. government agencies and to industry. To do 

this, NIST must review thoroughly the current and projected availability of all NIST/NBS 

products and services cited in CFR references. Additionally, to address specifically the 

regulatory needs of U.S. federal agencies, NIST should approach regulators to offer its 

expertise and knowledge and to explain how best to use and reference NIST 

measurement services and products in their regulations. Specific recommendations are 

given in section 9 below. 

NIST’s responsibility to ensure the integrity of the nation’s measurement system is a 

unique and vital component that contributes to the welfare of the nation. Carrying out the 

recommended actions below will increase NIST’s value to U.S. federal agencies, industry 

and other stakeholders. 

9. Recommendations 

NIST should ensure that its products and services are cited appropriately in regulations 

and that they are technically valid. Relevant NIST Laboratories should carry out a 

review to confirm the findings of this study and determine the technical validity of the 

references. Then, the relevant program responsible for the cited product or service 

should either identify alternative or new products and services that can serve the purpose 

of the original citation or other viable options. If NIST Laboratories have followed a 

deliberate transition strategy for certain products and services, then this information 

should be documented and presented in a form that is understandable and useful to 

regulators. 

NIST Technology Services can work with NIST Laboratories to evaluate the out-of-date 

citations identified in this report and determine a course of action for each one. Once 

NIST has identified alternative resources or confirmed NIST’s inability to deliver a cited 

product and service, NIST must determine the best way to contact regulators and others 

that may provide support in addressing the technical and administrative issues that were 

identified. 

NIST should approach regulators about: (a) current NIST/NBS products and services that 

may better suit agencies’ needs; (b) the lack of availability of some cited NIST/NBS 

products, suggesting that they may be inadequate and providing possible replacements for 

outdated citations; (c) the meaning and significance of traceability and how to 

demonstrate it, since some regulations specify “traceability to NIST/NBS” or 

“traceability to NIST standards”, without explicitly identifying the required standard to 

which traceability should be established. 

Appendix 1 
In addition NIST should support agencies in correcting factual mistakes such as; (a) 

incorrect references to NIST as the National Institute of/for Science and Technology or 

the National Institute of/for Standards and Technologies, or still to the National Bureau of 

Standards; (b) regulations that refer to both NBS and NIST in the same paragraph. The 

authors note that it may be possible to effect some of these corrections by working 

directly with the U.S. National Archives and Records Administration (NARA), which is 

responsible for maintaining an electronic database of the CFR. 

Finally, NIST should establish a policy that, in the future, when Laboratories consider 

termination of a product or service, they should first determine if it is referenced in the 

CFR and provide appropriate alternatives or work with the relevant agency to change or 

withdraw particular references. 

We believe this is a significant undertaking but one that will enhance the value of NIST 

products and services to all stakeholders and will clearly identify NIST as the leader of 

the Nation’s Measurement System, which includes responsibilities such as: 

• Identifying unmet measurement needs of U.S. industry, commerce, regulatory 

agencies, and national defense; 

• Identifying needed de-facto national standards of measurement; 

• Initiating collaborations with and among government agencies and industrial 

institutions with unmet measurements needs and responding appropriately; 

• Developing or collaborating with others on developing measurements, methods 

and standards to fill identified national measurement needs; and 

• Supporting other government agencies with special measurement needs.
