I. THE COMMERCIAL PRODUCTS LAP AT A GLANCE

This document presents the operational and technical requirements of the

Laboratory Accreditation Program (LAP) for Commercial Products, including paint

and related coatings and materials, paper and related products, and mattresses.

All of the steps leading to accreditation are described. Explanation of

technical requirements indicate how the NVLAP criteria are applied.

The laboratory accreditation program for conmercial products was established in

1984 in response to a request from the International Coalition for Procurement

Standards (ICPS). The purpose of the LAP is to enable accreditation of

laboratories so that purchasing authorities may meaningfully specify in their

contracts that materials be tested by laboratories accredited under NVLAP.

Accreditation is available to any organization, including commercial

laboratories; a manufacturer's laboratories ; and Federal, state, or local

government laboratories that test paint, paper, or mattresses using the test

methods listed in the Appendix.

Products covered: Paint and related coatings and materials, paper and related

products, and mattresses.

Period of accreditation: One year

On-site assessment frequency: After initial application and every two years

thereafter

Proficiency testing:

Paint: Participation in the Paint Proficiency Testing Program conducted by

Collaborative Testing Services, Inc. (CTS) and the Federation of

Societies for Coating Technology.

Paper: Participation in the Paper Proficiency Testing Program conducted by

CTS and the Technical Association of the Pulp and Paper Industry

(TAPPI).

Mattresses: Proficiency testing program to be developed.

Proficiency testing frequency: In accordance with the CTS programs described

above

.

Fees: Administrative fee, one-time initial fee, and total test melnod fee

based on the number of test methods selected. Proficiency testing fee

paid directly to CTS.
II. INTRODUCTION

Background

The U.S. Department of Commerce, National Bureau of Standards (NBS) administers

the National Voluntary Laboratory Accreditation Program (NVLAP). NVLAP's

function is to accredit public and private testing laboratories based on evaluation of their technical qualifications and competence for conducting

specific test methods in specified fields of testing. Accreditation is granted

on the basis of conformance with criteria published in the Code of Federal

Regulations as part of the NVLAP procedures (15 CFR Part 7). (See Appendix.)

This document is intended for use by staff of accredited 1 aboratories, those

seeking accreditation, other laboratory accreditation systems, and others

needing information on the requirements for NVLAP accreditation under this LAP.

This document is generally included in the NVLAP Application Package along with

General Application Forms, Test Method Selection Lists, and other materials

needed to apply for or renew accreditation. It presents the administrative and

operational procedures and technical requirements of the LAP and should be

retained and be readily accessible to laboratory personnel.

NVLAP Accreditation

Accreditation is granted only after thorough evaluation of the applicant has

demonstrated that all NVLAP criteria have been met. The accreditation is

formalized through issuance of a Certificate of Accreditation, Scope of

Accreditation and publicized by announcement in various government and private

media.

NVLAP accreditation is available to commercial laboratories, manufacturer's

in-house 1 aboratories, university laboratories. Federal, State, and local

government laboratories. Foreign- based laboratories may also be accredited by

NBS if they meet the same requirements as domestic laboratories and pay any

additional fees required.

Why NVLAP Accreditation ?

The reasons why a laboratory may wish to be accredited include: legal

requirements such as regulations or codes, contract specifications, and the

desire to be recognized as being demonstrably competent to meet the needs of

its clients.

For accreditation to be meaningful, it must be granted by a clearly credible

organization. NVLAP provides an unbiased third party evaluation and

recognition of performance as well as expert technical assistance to upgrade

laboratory performance.

2
Testing Laboratory Defined

NVLAP defines a "testing laboratory" as an organization that provides services

to measure, examine, test, calibrate, or otherwise determine the

characteristics or performance of products or systems.

Accreditation Defined

NVLAP accreditation means recognition of a testing laboratory's competence to

perform specific test methods in specified fields of testing. It means that

the laboratory's quality system, staff, facilities and equipment, calibration

procedures, test methods and procedures, records, and test reports, have been

evaluated and found to meet NVLAP criteria. NVLAP accreditation does not mean

a guarantee (certification) of laboratory performance or product test data; it

is a finding of laboratory competence.

III. ADMINISTRATIVE AND OPERATIONAL REQUIREMENTS

Note: Administrative and operational requirements presented here are generally

applicable to all NVLAP programs . Technical and proficiency requirements

are specifically applicable to this LAP.

LABORATORY CODE NUMBER

Each participating laboratory is assigned a four-digit laboratory code number.

The code number is used by the NVLAP staff for identification, filing,

recordkeeping, and database management. Participants are requested to put

their Lab Code number on all correspondence with NVLAP.

ACCREDITATION PERIOD

Accreditation is granted for a period specified in the LAP Application Package

(usually one year). The accreditation period begins on one of four dates:

January 1, April 1, July 1, or October 1. Once a laboratory has been assigned

an accreditation date, it retains that date as long as it remains in the

program. Accreditation expires and is renewed on that date.

RENEWAL

Each participating laboratory will be sent a renewal Application Package, well

in advance of the expiration date of its accreditation, to allow sufficient

time to complete the renewal process. The renewal application contains the same forms used for initial application, and the laboratory need only indicate

where changes have occurred from the previous period in personnel, equipment,

facilities, or the scope of accreditation desired.

With the exception of an initiation fee for new applicants, the technical

requirements and fees are the same as for initial accreditation. The

application and fees must be received by NBS prior to expiration of the

laboratory's current accreditation to avoid a lapse in accreditation.

PUBLICIZING ACCREDITATION STATUS

BY NVLAP

NVLAP publishes an annual Directory of Accredited Laboratories. The Directory

contains the name and address, scope of accreditation, contact person, and the

accreditation renewal date for each accredited laboratory. Supplements to the

Directory are published quarterly to cover interim accreditation actions

including initial accreditations, renewals, suspensions, terminations, and

revocations. The Directory is distributed nationally and internationally to

manufacturers , suppliers, retailers, professional and trade associations, code

groups, and government agencies.

4
BY LABORATORIES

Accredited laboratories are encouraged, within specified limits, to publicize

their accredited status. The major restriction is that advertising must not

imply product certification by NBS or the U.S. Government. Laboratories and

their clients may not reference their accredited status in consumer media, in

product advertising, or on product labels, containers or packaging.

A laboratory may cite its accredited status and use NVLAP logos on reports,

stationery, and in business and trade publications provided that it is clearly

indicated that it is the laboratory which is accredited. NVLAP Lab Bulletin

No. 3A provides more detailed guidance on how a laboratory may publicize its

accredited status and the statements which may be made. (See Appendix.)

COMPLIANCE WITH EXISTING LAWS

Accreditation does not relieve the laboratory of the need to observe and comply

with existing Federal, State, and local statutes, ordinances, or regulations

that may be applicable to its operations, including consumer protection and

antitrust laws.

ACCREDITATION PROCESS

Accreditation is granted following successful completion of a process which

includes submission of an application and payment of fees by the laboratory, an on-site assessment, resolution of deficiencies identified during the on-site

assessment, participation in proficiency testing, technical evaluation, and

administrative review. A diagram of the accreditation process is shown in the

figure below.

5
APPLICATION AND FEES

An Application Package is sent to a laboratory on request. It includes:

General Application Forms, a Fee Calculation Sheet, and this document. The

General Application Form must be completed and signed by an authorized

representative of the laboratory. The authorized representative is one who can act on behalf of the laboratory and commit it to fulfill the NVLAP

requirements. Before completing and signing the application, the authorized

representati ve should review all documents and become totally familiar with

NVLAP requirements . Although other laboratory staff may be designated to

perform activities, such as handling proficiency testing or receiving an assessor, the authorized representative is the only one who can authorize a change in the scope or nature of the application.

In general, the accreditation fee is composed of several parts, some of which

are fixed while others depend on the scope of accreditation desired and the

specifics of the LAP. The total accreditation fee must be paid before

accreditation can be granted. The individual parts of the accreditation fee

include, as appropriate : a one-time LAP initiation fee for new applicants, an administrative fee, test method fees, an assessment fee, and proficiency

testing fees. The fees for this LAP are shown in the Fee Calculation Sheet

included in the LAP Application Package.

The laboratory will be scheduled for an on-site assessment after payment of all

required fees and will be notified of any additional information which must be

supplied and of any applicable proficiency testing requirements which must be

completed for the technical evaluation.

APPROVED SIGNATORY

Under NVLAP criteria, an accredited laboratory must have one or more

individuals or laboratory positions designated as having responsibil ity for

signing " all test reports endorsed with the NVLAP logo ." This is the person(s)

to whom NVLAP, laboratory clients, or others would go in case of questions or problems with the report.

There is no formal requirement for nomination or approval of persons or laboratory positions designated as approved signatories. The laboratory should

inform NVLAP of its appointments by completing the appropriate sections in the

application for accreditation. Approved signatories should be: persons or positions with adequate responsibility or authority within the organization,

with adequate and appropriate technical capabilities, and without conflict of

interest. The approved signatory may be the authorized representative who is

responsible for signing the NVLAP Application Form.

Laboratory test reports carrying the NVLAP logo need not be signed individually

by the approved signatory . Test report forms may be preprinted with the

required information. Forms that are electronically or computer generated may

have the information printed along with the test results.

6
TECHNICAL EXPERTS

NVLAP uses Technical Experts (TEs) as assessors and evaluators. These are individuals knowledgeable in the testing field being evaluated. They may be

engineers or scientists currently active in the field, consultants, college

professors or retired persons. They are selected on the basis of their

professional and academic achievements, experience in the field of testing,

management experience, and tact in dealing with people. Their services are generally contracted as required; they are not NVLAP staff members.

Assessors are TEs selected to conduct an on-site assessment of a particular

laboratory on the basis of how well their individual experience matches the

type of testing to be assessed, as well as absence of conflicts of interest.

The laboratory has the right to appeal the assignment of an assessor and may

request an alternate.

Eval uators are TEs selected to review the record of the laboratory as a whole,

including the application, assessment report, deficiencies, corrections to

deficiencies, and proficiency test results and, based on this record, to

recommend whether or not a laboratory should be accredited. The evaluators are matched to the type of testing being evaluated and are selected to avoid

conflicts of interest.

ON-SITE ASSESSMENT

Before initial accreditation and periodically thereafter, an on-site assessment

of each laboratory is conducted to determine compliance with the NVLAP

criteria. The assessment is conducted by one or more NVLAP assessors selected

on the basis of their expertise in the field of testing to be reviewed.

Assessors use checklists developed by NVLAP so that each laboratory receives an assessment comparable to that received by others. However, assessors have

considerable latitude to make judgments about a laboratory's compliance with

the NVLAP criteria, depending on the assessor's experience and the unique

circumstances of the laboratory.

Each laboratory will be contacted to arrange a mutually agreeable date for an asessment. The time needed to conduct an assessment varies, but two days is the

norm. Every effort is made to conduct an assessment with as little disruption

as possible to the normal operations of the laboratory. During the assessment

the assessor will carry out the following functions:

- meet with management and supervisory personnel responsible for the

laboratory's activities (for which accreditation is being sought) to

review the assessment process with the individuals involved and to set

the assessment agenda.

- examine the quality assurance system employed by the laboratory. The assessor may select and trace the history of one or more samples from

receipt to final issuance of test reports. The assessor will conduct a thorough review of the laboratory's quality manual or equivalent,

evaluate the training program, examine notebooks or records pertain ng

to the samples, check sample identification and tracking procedures,

determine whether the appropriate environmental conditions are maintained, and examine copies of completed test reports.

7
- review records of periodic internal audits, use of check samples or participation in round robin testing or other similar programs.

- review personnel records including resumes and job descriptions of key

personnel, competency evaluations for all staff members who routinely

perform the testing for which accreditation is sought, calibration or verification records for apparatus used, test reports, and sample

control records.

- observe demonstrations of testing techniques and discuss them with the

technical personnel to assure their understanding of the procedures.

- examine major equipment, apparatus, and facilities.

At the conclusion of the assessment, the assessor will conduct an exit briefing

to discuss his or her observations with appropriate laboratory staff and call

attention to any deficiencies uncovered. A written summary of any deficiencies

discussed will be left at the laboratory . The assessor will forward the

assessment forms and a written summary to NBS.

If deficiencies have been noted, the laboratory

must, within 30 days of the date of this

notification provide NVLAP with documentation or certification, by the authorized representative,

that the specified deficiencies have been

corrected or that sp cific actions are being

taken to correct the deficiencies.

A laboratory applying for initial accreditation may request an extension to

complete required corrections.

If any deficiencies are noted at laboratories which are currently accredited,

such deficiencies must be corrected within 30 days after notification or the~

laboratory may face possible revocation, suspension, or expiration of its

accreditation. Any test equipment that is identified as out-of-cali brat ion,

should not be used until corrective action has been completed. All

deficiencies noted for corrective action will be subject to thorough review and

verification during subsequent assessments and technical evaluations.

MONITORING VISITS

In addition to regularly scheduled assessments, monitoring visits may be

conducted by assessors or by NBS staff at any time during the accreditation

period. Monitoring visits may occur for cause or on a random selection basis.

These visits serve to verify reported changes in the laboratory's personnel,

facilities, and operations or to explore possible reasons for poor performance

in proficiency testing.

The scope of a monitoring visit may range from checking a few designated items

to a complete review. Failure to cooperate with NVLAP assessors will be

grounds for initiation of adverse accreditation action. No additional fee is

required for the monitoring visit.

8
PROFICIENCY TESTING

Proficiency testing is an integral part of the NVLAP accreditation process.

Demonstration of appropriate facilities, equipment, personnel, etc. is

essential, but may not be sufficient for the evaluation of laboratory

competence. The actual determination of test data using special proficiency

testing samples provides NVLAP with a way to determine the overall

effectiveness of the laboratory.

Proficiency testing is a process for checking actual laboratory testing

performance, usually by means of interlaboratory comparisons. Each LAP has

unique proficiency testing requirements . The data are analyzed by NVLAP and

summary reports of the results are sent back to the participants.

For many test methods, results from proficiency testing are very good

indicators of a laboratory's testing capability. Information obtained from

proficiency testing helps to identify problems in a laboratory. When problems

are found, NVLAP staff members work with the laboratory staff to solve them. If

problems with the test method are suspected, NVLAP provides information to the

appropriate standards-writing bodies.

The specific proficiency testing requirements for this LAP are included in

Section V of this document.

TECHNICAL EVALUATION

After a laboratory has completed all the technical requirements of a LAP and is

ready for an accreditation action, a final technical evaluation is conducted by

experts chosen for their experience and knowledge of the pertinent test

methods. They review records on each applicant laboratory and base their

evaluation on:

- information provided on the application;

- on-site assessment reports;

- actions taken by the laboratory to correct deficiencies;

- results of proficiency testing; and

- information from any monitoring visits of the laboratory.

If the technical evaluation reveals additional deficiencies, written

notification describing them will be made to the laboratory. The laboratory

must respond within 30 days of such notification and provide documentation or certification by the authorized representati ve that the specified deficiencies

have been corrected. Clarification of some issues may be requested by

telephone. All deficiencies must be corrected before accreditation can be

granted or renewed.

9
ADMINISTRATIVE REVIEW

After the technical evaluation has been completed, the NVLAP staff prepares an administrative recommendation that the laboratory either be granted or denied

accreditation. This recommendation is based on a review of the technical

evaluation and other records to ensure that all NVLAP technical, financial and

administrative obligations have been satisfied.

ACCREDITATION ACTIONS

Acting for the Director of NBS, the Director of the NBS Office of Product

Standards Policy makes the following decisions.

Accreditation If accreditation is recommended, the recommendation forms the

basis for granting accreditation. A Certificate of

Accreditation will be issued to the laboratory.

Denial If denial is recommended, the laboratory is notified of a proposal to deny accreditation and the reason (s) therefor.

Suspension If a laboratory is found to have violated the terms of its

accreditation, the accreditation can be suspended. The

laboratory will be notified of the reasons for and conditions

of the suspension and the action(s) that the laboratory must

take to have accreditation reinstated.

Revocation If a laboratory is found to have violated the terms of its

accreditation, the laboratory is notified of a proposal to

revoke accreditation and the reasons therefor. The laboratory

may be given the option of voluntarily terminating

accreditation. If accreditation is revoked, the laboratory

must return its Certificate of Accreditation and cease use of

the NVLAP logo on any of its reports, other correspondence, or advert i si ng.

If denial or revocation has been proposed, the laboratory may request a hearing, under United States Code 5 U.S.C. 556, within 30 days of the date of

receipt of the notification. If a hearing is not requested, the action becomes

final upon the expiration of that 30-day period.

After a participant's accreditation has been terminated, whether voluntarily or through adverse action, the accreditation certificate must be returned to

NVLAP. If a laboratory elects not to renew or wishes to voluntarily terminate

its accreditation at any time, the notification of such intention should be

forwarded to NBS in writing.

10
'IV. TECHNICAL REQUIREMENTS

The requirements discussed in this section interpret the NVLAP criteria for

application to the Commercial Products LAP. These requirements do not

supersede the published NVLAP criteria which are included in the Appendix.

SCOPE OF THE LAP

The Commercial Products LAP covers tests for paint and related coatings and

materials, paper and related products, and mattresses. The test methods for

which a laboratory may seek accreditation are listed in the Appendix. Other

test methods may be added to the LAP, upon request, if they are found to be

appropriate.

The 127 paint test methods are divided into four categories:

(1) Measurements of intrinsic physical properties;

(2) Measurements of performance and performance change;

(3) Measurement of chemical properties and compositions; and

(4) Test sample conditioning and preparation.

The 61 paper test methods are also divided into four categories:

(1) Paper and paperboard-;

(2) Paper specifications;

(3) Pressure sensitive tapes; and

(4) Packaging.

All of the six test methods for mattresses are in a single category.

QUALITY ASSURANCE SYSTEM

The key to a properly functioning organization is that it has and maintains a system of procedures and practices which assure the quality of its services.

To qualify for accreditation, an applicant must demonstrate that its quality

assurance systems ensure the technical integrity of its work.

DOCUMENTATION

A laboratory must have up-to-date documentation which thoroughly describes all

its procedures and practices. The written descriptions should contain such

items as the method of implementation, responsible personnel, recordkeep ing

system, operating procedures, procedures to employ in the event of unusual or non-standard circumstances, and scheduling. Written descriptions should

include at least the following topics:

11
- Organizational chart;

- Laboratory facilities and scope of services offered;

- Job/position description for all personnel;

- Personnel training procedures;

- Personnel competency assurance procedures;

- Test equipment inventory;

- Test equipment calibration, verification, and maintenance practices;

- Test performance plan;

- Specimen selection, handling, analysis, control, and identification;

- Data handling and reporting;

- Internal checks and audits;

- External standardization practices;

- Reference standards and/or materials; and

- Subcontracting practices and procedures for assuring quality

This documentation should be in the form of a manual but may be individual

sheets in various locations throughout the facility. If individual sheets are used, a central reference document must be available to indicate where the

sheets may be found. The documentation must be in a format and style which can

be easily understood by technicians. It must be readily accessible to all

staff members.

PERSONNEL

Training :

Each new staff member must be trained for assigned duties and existing staff

members must be retrained when testing equipment and/or protocols are changed

or they are assigned new responsibilities. Each staff member must receive (or

have had) training for assigned duties either through on-the-job training,

formal classroom sessions or through technician certification programs.

Competency :

In addition to training, the supervisor must evaluate the competency of each

staff member by observing the performance of each testing protocol each staff

member is authorized to conduct. The performance observation must be conducted

annually by the immediate supervisor or his designee. A record of the staff

member's performance must be placed in the personnel file, dated and signed by

the supervisor.

Technical Director :

The laboratory technical director shall be a professional experienced in the

testing area for which accreditation is desired. This individual should have

the technical competence and the supervisory responsibil ity to direct the work

of professionals and technicians in the appropriate area. Responsibility for

the quality assurance program may reside with the technical director or with

another individual having knowledge and experience in quality assurance who has

a direct line of communication to the technical director and other

organizational management.

12
The assessor will review resumes or other information to substantiate the

qualifications of the Technical Director and all key individuals.

Any organizational or personnel changes that could affect the performance of

the testing service (e.g., Technical Director, technical supervision,

responsibility for quality assurance program) shall be reported to NVLAP within

30 calendar days of such change.

EQUIPMENT AND FACILITIES

A laboratory must have adequate equipment to perform the type(s) of testing for

which capability is claimed. This includes adequate space to perform the

testing, environmental controls, adequate testing equipment, adequate safety

systems and either properly calibrated laboratory standards or access to the

services of a competent calibration laboratory.

EQUIPMENT MAINTENANCE AND CALIBRATION

All equipment used in the testing of the commercial products and to perform

quality control must be adequately maintained so that it can accomplish the

required measurements.

Measurement or quality control equipment that is inherently subject to change

due to use or passage of time, must be periodically calibrated. Calibration

means comparison with a reference standard so that the performance of a measuring instrument may be determined with sufficient accuracy.

Calibrations of equipment may be performed by the laboratory or by an external

calibration service. All calibrations and characterizations must be done

against reference standards that are traceable to national standards maintained

by NBS or by an equivalent foreign national standards authority. To be

traceable means the ability to show that appropriate documented actions were

taken to compare (either directly or indirectly) a reference standard with a national standard.

The reference standards used and the environmental conditions at the time of

calibration must be documented for all calibrations. Calibration records and

evidence of the traceability of the reference standards used must be made

available for inspection during the on-site visit.

Testing equipment or verification records should include the following:

equipment name or description; model, style, or serial number; manuf acturer

;

notation of all equipment variables requiring verification; the range of

verification; the resolution of the instrument and its allowable error;

verification date and schedule; date and result of last calibration; identity

of the laboratory individual or external service responsible for calibration;

source of reference standard and traceability.

13
RECORDKEEPING

A laboratory must maintain a functional recordkeeping system. This means that

records must be easily accessible, in some logical order and contain complete

information on the subject. Records covering the following items are required

and will be reviewed during the on-site visit either in total or by selected

sampling:

- Staff training dates and results;

- Staff competency review dates and results;

- Testing equipment calibration and maintenance;

- Results of incoming inspection of materials;

- Comprehensive logs of test activities;

- Results of internal and external equipment checks, measurement assurance

programs, quality audits, etc.;

- Test data and reports; and

- Tracking and logging of samples tested.

Sample tracking and logging records should trace the movement of each sample

through the testing facility from its receipt through all the tests performed

to the final test report. Dates, times, condition of item and personnel

involved should all be included.

TEST REPORT

The test report to the client must include:

- Name and address of laboratory;

- Pertinent dates and identifying numbers;

- Client name;

- Description or identification of each sample;

- Identification of the test method, procedures, or specifications;

- Identification of known deviations, additions to, or exclusions from the

test method;

- Measurements, examinations, or derived results, and identification of

test anomalies;

- A statement, if necessary, as to whether or not the test results comply

with the requirements of product or project specifications;

- Signature of person having technical responsibil ity for the test report;

and

- All other items required by the test method.

Records of these reports must be maintained for at least three years.

14
V. PROFICIENCY TESTING

Proficiency testing is an integral requirement of the NVLAP evaluation process.

NBS either conducts the proficiency testing program for the LAP or determines

if a collaborative reference program or round-robin testing program exists

which can meet the testing requirements for the LAP. The proficiency testing

requirements for the Commercial Products LAP are described below.

PAINT AND RELATED COATINGS AND MATERIALS

In 1983, the Federation of Societies for Coatings Technology (FSCT), in

association with Collaborative Testing Services, Inc., (CTS), McLean, Virginia,

established a proficiency testing program for paints and coatings. The program

provides participating testing laboratories a means of periodically comparing

the results of their testing with those of other laboratories in the paint and

coatings industry.

Six times a year, CTS distributes samples, instructions, and data sheets so that participating laboratories can perform two different test methods.

Laboratories accredited by NVLAP for testing paints and related coatings are required to be enrolled in the CTS/FSGT program for paints and coatings. The

laboratory applies and pays proficiency testing fees directly to CTS. CTS

provides NVLAP with summary reports of the test results for each test method

and, with permission of the laboratory, identifies those laboratories in the

.report which are accredited or seeking NVLAP accreditation.

The test methods included in the CTS proficiency testing program for paints and

coatings, which are applicable to the Commercial Products LAP, are listed

below.

PAPER AND RELATED PRODUCTS AND PACKAGING

In 1969 the National Bureau of Standards (through the Research Associate

Program) and the Technical Association of the Pulp and Paper Industry (TAPPI)

established a Collaborative Reference Program for Paper. The purpose of this

program is to provide participating laboratories a means of periodically

comparing the level and uniformity of their testing with those of other

laboratories. NBS no longer participates in the program, which is operated and

maintained by Collaborative Testing Services (CTS). TAPPI provides a Technical

Advisory Committee to guide the program.

CTS distributes samples, instructions, and data sheets periodically during the

testing year. Laboratories accredited by NVLAP for testing paper and related

products and packaging are required to be enrolled in the CTS/TAPPI program.

The laboratory applies and pays proficiency testing fees directly to CTS. CTS

provides NVLAP with summary reports of the test results for each test method

and, with permission of the laboratory, identifies those laboratories which are accredited or seeking accreditation under NVLAP.

Samples of two types of paper are distributed six times during the program

year. Corrugated fiberboard samples are distributed three times per year.

Lab Bulletin No. 3A January 1, 1985

INFORMING THE PUBLIC OF YOUR ACCREDITATION STATUS

Summary

This Bulletin supersedes NVLAP Lab Bulletin No. 3 dated October 1, 1981. It

reflects significant changes made to the NVLAP procedures (Title 15, Part 7, of

the Code of Federal Regulations) which became effective on December 10, 1984.

The Bulletin is addressed primarily to personnel at accredited laboratories who

are responsible for communicating the laboratory's accreditation status to

clients and the public, through advertising, issuance of test reports, use of

the NVLAP logo, etc.

The Bulletin's purpose is to "provide guidance on referencing the laboratory's

accredited status, and use of the NVLAP logo by the laboratory and its

clients," in accordance with provisions of the NVLAP Procedures.

Background

NVLAP was established to assist industry and government in identifying

competent testing laboratories. NVLAP accreditation means that a laboratory is

competent to perform specific test methods in selected fields of testing. The

NVLAP Procedures are the bases upon which the entire program operates and

accomplishes accreditation of laboratories. Parts A and B of the Procedures

provide general information and the method by which a new Laboratory

Accreditation Program (LAP), in a new field of testing, may be requested and

established. Parts C and D of the Procedures , of more concern to accredited

laboratories, describe how a laboratory becomes accredited and the conditions

and criteria for initial and continued accreditation. This Bulletin is

concerned principally with issues in Part D of the Procedures.
Requirements and Guidance

Lab Bulletin No. 3A

Page 2

January 1, 1985

To become accredited and maintain accreditation a laboratory shall:

limit the representation of the scope of its accreditation to only those

tests or services for which accreditation is granted

A laboratory accredited by NVLAP may use the following statement on its

letterheads and in trade or other publications: "Accredited by the National

Bureau of Standards, National Voluntary Laboratory Accreditation Program for

selected test methods for --(identify product or service area(s))." This

statement could, for example, be placed at the bottom of the laboratory

1 etterhead

.

A laboratory's letterhead containing a reference to its NVLAP accreditation may

be used in any direct solicitation for business from potential customers. It is

recommended that a copy of the NVLAP Certificate and Scope of Accreditation be

appended to such a solicitation.

To become accredited and maintain accreditation a laboratory shall:

limit advertising of its accredited status to letterheads, brochures,

test reports, and professional, technical, trade, or other laboratory

services publications, and use the NVLAP logo under guidance provided by

NBS

A statement about NVLAP accreditation and the NVLAP logo may be used on reports

and data sheets containing test data obtained by a laboratory provided the

tests or services are performed in accordance with the terms of its

accreditation. The NVLAP logo may not be used on test reports or data sheets

during any period of suspended or expired accreditation or after voluntary or involuntary termination of accreditation.

The nature or type of product advertising prohibited by NVLAP procedures

includes any advertising that is intended to encourage a consumer to purchase a product because it was tested by an accredited laboratory, whether that

advertising appears in consumer media, the business media, or at a point of

sale to consumers.

News stories and advertising by laboratories of their accredited status in the

trade press is not only permissible but encouraged. The use of advertisements

in the trade press is consistent with NVLAP procedures.

The "consumer media" to be avoided include popular periodicals such as Time,

Good Housekeeping, etc., and newspapers such as the Washington Post or the New

York Times. The term "consumer media" does not include business publications

such as Barron's, or the Wall Street Journal which are oriented to the business

community and in which products per se normally are not advertised.
Lab Bulletin No. 3A

Page 3

January 1, 1985

To become accredited and maintain accreditation a laboratory shall:

inform its clients that the laboratory's accreditation or any of its test

reports in no way constitutes or implies product certification,

approval, or endorsement by NBS

Laboratory accreditation by NBS confers recognition that a laboratory has been

found competent to perform specific test methods or services in a selected

field(s) of testing. Laboratories must avoid all inference that accreditation

under NVLAP carries with it an endorsement, approval, or recommendation of the

products tested by the laboratories.

To become accredited and maintain accreditation a laboratory shall:

assure that all test reports endorsed with the NVLAP logo are signed by

an approved signatory

An approved signatory is an officer or employee of the laboratory, identified

by name or position, who has been accepted by NVLAP as being responsible for

the issuance of test reports under this condition of NVLAP accreditation. A

laboratory seeking initial accreditation or reaccredi tation must specify (a) one or more individuals, or (b) position(s) within the organization for which

it requests acceptance as an approved signatory.

Computer or machine generated test reports that contain the NVLAP logo need not

be signed but must have the printed name of the approved signatory.

Questions About Accreditation

If you have questions about what is an acceptable method of advertising in areas not specifically covered in this Lab Bulletin^or about the propriety or acceptability of a particular statement, advertising media, or use of

information about your NVLAP accreditation status, please contact NVLAP before

your publicity program is implemented.
