- Information Offices. National Office, Regional Offices, State plan States, OSHA Training Institute.
- Action Required. The responsible and the action offices will implement the policies,
procedures, and guidelines contained in this Instruction.
- Regional and State Impact.
Regional Administrators (RAs) and Area Directors will ensure that this Instruction is
forwarded to appropriate administrative and compliance staff to review for changes
pertinent to their areas of responsibility. RAs will also ensure that this Instruction is
forwarded to each State Designee. As detailed in STP 2-1.147A, State Plan States are
encouraged to adopt standards that rely on Nationally Recognized Testing Laboratories
recognized by Federal OSHA, but State Plan States choosing to establish their own
program for recognizing testing laboratories may do so as long as they:
- Accept certifications of NRTLs recognized by OSHA for testing of equipment
and materials where State safety requirements are the same as the Federal.
- Ensure that organizations receiving State recognition understand that it applies
only within that State.
- Establish a program which is at least as effective as the OSHA NRTL Program.
- Director of the Office of Technical Programs and Coordination Activities.
- Administers the NRTL Program.
- Establishes, ensures compliance with, and originates policies and
procedures for the NRTL Program; modifies or clarifies this directive, as
- Ensures the performance of all activities necessary for processing
applications for NRTL recognition , including the preparation of Federal
Register (FR) notices required for activities under the NRTL Program.
- Director of the Directorate of Technical Support.
- Oversees the administration of the OTPCA.
- Reviews and approves policies and procedures for the NRTL Program.
- Reviews and approves Program-related FR notices originated by OTPCA,
following their approval by the Office of the Solicitor (SOL).
- Office of the Solicitor.
- Reviews and approves Program-related FR notices originated by OTPCA,
for legal issues and requirements.
- Reviews and approves directives for the NRTL Program, including
- Provides legal advice on other regulatory or legal issues regarding the
- Assistant Secretary.
- Reviews and approves Program-related FR notices originated by OTPCA.
- Approves letters of recognition or other formal notifications for
organizations recognized by OSHA as Nationally Recognized Testing
- Definitions. See Appendix B.
- Significant Changes. This Instruction updates the process for processing applications for
recognition and the process for monitoring organizations after they are recognized by
- Background. The Occupational Safety and Health Administration (OSHA) published a
final rule on April 12, 1988 that modified those provisions in 29 CFR Part 1910 that
require product safety "certification" (by whatever term used) to specify that these
certifications be accomplished by a nationally recognized testing laboratory (NRTL).
The final rule also established a new section, 29 CFR 1910.7 and Appendix A to this
section, which are referred to as the "NRTL Program regulations" or "Program
regulations" in this directive. As a result of this new section, an organization seeking to
perform the "certification" required in Part 1910 must be "recognized" by OSHA and
must apply to the OSHA NRTL Program for the recognition. The Program regulations
include the requirements OSHA must follow in processing an application for recognition
and the main criteria that OSHA must use to evaluate the qualifications of an organization
Prior to publication of the rule, the provisions in 29 CFR Part 1910 either had explicitly
required or had implied that product certifications be performed only by Underwriters
Laboratories, Inc. (UL) and Factory Mutual Research Corporation (FMRC). Other
testing organizations claimed these provisions caused them to suffer economic losses, and
sought the changes effected by the adoption of the rule. To date, a number of
organizations, including UL and FMRC, have been recognized by OSHA as NRTLs.
In 1991, OSHA issued Instruction PUB 8-1.9, which provided information on the
"Nationally Recognized Testing Laboratory (NRTL) Accreditation Program (29 CFR
1910.7)." This Instruction included background on section 1910.7 and on the
requirements and process of recognition, and listed general responsibilities of the
Program and of Program staff. The Instruction however did not detail the policies or
procedures to be used to process applications for recognition, or to monitor the
organizations recognized by OSHA. In this current Instruction, the Program is simply
referred to as the "NRTL Program."
On March 9, 1995, OSHA published a "Notice of interpretation" for the Program (60 FR
12980). This notice addressed "in particular those programs under which the NRTL
controls and audits, but does not itself generate, the data relied upon for product
certification." Nine "programs" were identified, along with the criteria that the NRTL
must meet to permit its use. Eight of the programs are optional. See the 3/9/95 FR notice
for details about these programs and Appendix C for additional information.
- Program Information.
- Obtaining Information. Information about the NRTL Program may be obtained
by selecting "Programs" on the OSHA home site on the world wide web
(http://www.osha.gov), or by calling (202) 693-2110 or contacting:
Occupational Safety and Health Administration
US Department of Labor
200 Constitution Avenue NW, Room N3653
Washington, DC 20210
- Application Guidelines. The Guidelines may be obtained from the above address
and are available on the web site for the NRTL Program.
- Public and Confidential Information. Copies of the applications submitted by
organizations are available to the public via the OSHA Docket Office. All
information or documents submitted in an application becomes public
information unless confidentiality can be justified by the applicant.
- List of NRTLs and Specific References to NRTL Approval. The list of
organizations recognized as NRTLs can be obtained by contacting the NRTL
Program. A listing of the specific references in OSHA's standards to NRTL
approval can also be obtained. OSHA will make both lists available to the public
in hard copy and on the web site for the NRTL Program.
Chapter 2: Overview
- Purpose. This Chapter provides an overview of the NRTL Program.
- Scope of Program. The NRTL Program recognizes mainly private sector organizations
that provide product safety testing and certification services to manufacturers. The
testing and certification are done, for purposes of the Program, to U.S. consensus-based
product safety test standards. These test standards are not developed or issued by OSHA,
but are issued by U.S. standards organizations, such as the American National Standards
Institute (ANSI). The range of products covered by the Program is limited to those items
for which OSHA safety standards require "certification" by an NRTL (see Appendix A
for a table of these types of products). The requirements mainly affect electrical
- Eligibility and Requirements For Recognition as an NRTL.
- Eligibility. Any testing organization based within or outside the United States
may apply to the NRTL Program for recognition. They may be organized as for-profit or as nonprofit entities. However, approval to recognize a foreign-based
organization is contingent on a determination by the US Trade Representative on
"equal treatment" (as required in I.A.1 of Appendix A to 29 CFR 1910.7).
- Requirements. Recognition is granted to organizations that meet the requirements
established by OSHA for an NRTL. The Program regulations list the
requirements, which are summarized as follows:
- Capability (including proper testing equipment and facilities, trained staff,
written test procedures, and quality assurance programs) to test and
evaluate equipment for conformance with appropriate test standards
- Adequate controls for the identification of certified products, conducting
follow-up inspections of actual production
- Complete independence from users (i.e., employers subject to the tested
equipment requirements) and from any manufacturers or vendors of the
- Effective procedures for producing its findings and for handling
complaints and disputes
- Scope of Recognition. The NRTL's scope of recognition, which it must request, consists
of the specific test standard(s), site(s) and program(s) for which it is recognized.
- Test Standards. The NRTL's recognition from OSHA is not for products, but for
the appropriate test standards covering a type of product(s). OSHA uses the
criteria found in paragraph IV of Appendix D in approving test standards.
- Sites. Recognition is site-specific and not necessarily granted to all testing
facilities operated by an organization. However, an NRTL may accept test data
generated by one of its sites that is not recognized, provided certain conditions are
met (see policy on Sites in Appendix C). In addition, OSHA does not generally,
but may, limit the recognition of a site to testing or certification of specific types
of products, i.e., to specific test standards, or to specific types of programs (see
next paragraph for more information).
- Supplemental Programs. The March 9, 1995 Federal Register (FR) notice (60 FR
12980) lists nine (9) programs and procedures (collectively, "programs"). An
NRTL may use eight of these programs (referred to as supplemental programs) to
control and audit, but not actually to generate, the data or support services relied
upon for its testing and certification of products. The names of these nine
- The basic procedure (i.e, program)
- Acceptance of testing data from independent organizations, other than
- Acceptance of product evaluations from independent organizations, other
- Acceptance of witnessed testing data
- Acceptance of testing data from non-independent organizations
- Acceptance of evaluation data from non-independent organizations
(requiring NRTL review prior to marketing)
- Acceptance of continued certification following minor product
modifications by the client
- Acceptance of product evaluations from organizations that function as part
of the International Electrotechnical Commission Certification Body
- Acceptance of services other than testing or evaluation performed by
subcontractors or agents
The NRTL's initial recognition will always include the first or basic program,
which requires that all product testing and evaluation be performed in-house by
the NRTL that will certify the product. In addition, program number nine (9)
addresses the criteria for subcontracting services such as calibration, security,
follow-up, and maintenance. As a practical matter, an applicant should request
recognition for this program in its application since NRTLs commonly
subcontract these types of services. See the 3/9/95 FR notice for details about
these programs and Appendix C for additional information.
- Recognition Process.
- Application. Application Guidelines for recognition as an NRTL, and for
expansion or renewal of recognition, are available to any interested organization.
(see Chapter 1)
- Application Review. Program staff reviews the application for completeness and
for adequacy. The applicant is given an opportunity to correct any deficiencies in
its application. When the review is completed, OSHA will send a letter to the
applicant to formally accept or reject the application. (see Chapter 3)
- On-site Review. Following acceptance of the application, one or more OSHA
assessors performs the on-site review of the applicant's testing and administrative
facilities. The review typically takes two or three days, but varies with the size of
the applicant organization and its proposed scope of recognition. After the
review, the assessor (or lead assessor, if more than one) sends a report of the
findings to the applicant to obtain its written response to any corrective actions
(i.e., deficiencies) noted. The applicant must respond by a mutually-agreed-upon
or other appropriate deadline. (see Chapter 4)
- Evaluation and Approval. After the applicant submits its response, the assessor
completes the On-Site Review Report describing the findings of the site visit and
the preliminary evaluation of the application. This report and the application are
the main basis for the final evaluation and for the notice of the preliminary
finding, which OSHA publishes in the Federal Register for public comment.
Through this notice, the Agency presents its finding on whether the applicant has
or has not met the requirements for recognition. OSHA makes a final decision
following resolution of any significant issues raised by timely comments. The
Agency then submits the notice of final decision for publication in the Federal
Register to officially approve or deny the recognition. (see Chapter 5)
- Notification. If the recognition is approved, the Assistant Secretary formally
notifies the applicant of the decision and sets forth the terms of recognition. The
recognition remains in effect for a five-year period. At the end of the initial
five-year period, the NRTL must apply for renewal of recognition. If the
recognition is denied, the Director notifies the applicant of the decision.
- Types of Applications and Other Actions. After its initial recognition, the NRTL may
seek to expand the scope of its recognition for additional test standards, sites or programs.
In addition, the NRTL must submit a request to renew its recognition prior to the end of
its initial five-year recognition period. The process OSHA uses for expansion or renewal
request is similar to the process for initial recognition. However, an on-site review may
not be required per the guidelines in Chapter 3. As a result, the time to process these
applications is often shortened. Two additional recognition-related actions are voluntary
termination and revocation of recognition. See Chapter 6 for more details.
Chapter 3: Application Review
- Purpose. This chapter sets forth the procedures for reviewing applications from
organizations seeking recognition, expansion, or renewal as an NRTL.
- Review Procedures.
- Application Receipt. Program staff establishes a Case File (for initial
applications), sends an acknowledgment to the applicant, and sends a copy of the
applicant's letter received with the application to appropriate staff. All materials
that the applicant has justified as confidential will be maintained secure in the
Case File only, and not in public files (see Chapter 1). In addition, for foreign
applications, the Program staff:
- Sends a copy of the application letter to the US Trade Representative
(USTR) if OSHA has not previously made a decision on reciprocity or
equal treatment by the foreign country. USTR makes a determination of
that country's compliance with the equal treatment provision in Appendix
A to 29 CFR 1910.7. OSHA will consider USTR's determination in its
decision to grant the recognition. No letter is sent if a determination is not
needed or has already been made.
- Performs any additional procedures for foreign applications covered under
any special agreements with a foreign country, to comply with provisions
of the agreement.
If an application is frivolous or grossly incomplete or inadequate, the Director
returns the application, notifying the applicant in writing that processing cannot
proceed and explaining why this action is necessary, and takes no further action.
The Director processes any future application from the applicant as a new
application, following the review procedures in this Appendix C.
- Application Review and Discussion (Telephone Contact). Program staff:
- Follows the procedures in Appendix D, and makes a determination
regarding the completeness and adequacy of the application.
- Discusses the results of the review with the Director and then with the
applicant, noting any deficiencies found or clarifications needed.
- Application Acceptance. If the application is determined to be complete and
adequate, the Director sends a letter to the applicant to accept the application,
noting that such acceptance is not a commitment on OSHA's part to recognize the
applicant. If the application is incomplete or inadequate, the Director sends a
letter to the applicant, detailing the deficiencies and the additional information
needed and requesting a response by an appropriate deadline.
- If the response does not adequately resolve the deficiencies, the Director
provides the applicant a final opportunity to respond within a given period.
If the applicant responds adequately within this period, the Director sends
an acceptance letter to the applicant.
- If the applicant does not respond adequately or fails to reply by any
deadline(s) provided or an approved extension of these deadline(s), the
Director sends a letter notifying the applicant that the application is not
accepted and the Case File is closed.
For expansion or renewal applications, the Program staff or the Director notifies
the NRTL of the acceptance or deficiency.
- Determination of On-site Review. When the application is accepted, the assigned
staff determines whether an on-site review is necessary. OSHA may choose not
to perform an on-site review under any of the following circumstances:
- The application is for an expansion or a renewal of recognition, and
OSHA determines adequate information is available from other valid
sources (e.g., previous applications of the applicant) to permit a reasonable
basis for evaluating the application;
- The application is for an initial recognition, and OSHA determines it
contains sufficient and credible information to permit a reasonable basis
for its evaluation; or
- The application is submitted pursuant to a valid agreement between an
organization and OSHA or between an organization and the U.S., and
OSHA participates in the agreement, that provides for the on-site review to
be performed by others.
If an on-site review is necessary, the assessor contacts the applicant to discuss and
schedule the on-site review. The assessor sends the applicant the site specific
agenda after the on-site review date(s) is finalized with the applicant and performs
the review in accordance with procedures in Chapter 4 of this directive.
- Amendments and Withdrawal by Applicant.
- Timing. An applicant may amend its application at any time prior to the
publication of the preliminary notice on the application. An amendment will be
processed following the review procedures in Appendix D. However, significant
changes may result in a delay in processing the application. An application may
be withdrawn by an applicant, without prejudice, at any time prior to the final
decision by the Assistant Secretary.
- Acknowledgment. The Director will acknowledge requests to amend or withdraw
- Application Prioritization. The Director will normally commence the processing of
applications on a first-come, first-served basis, and will continue processing to
completion unless delayed for valid reasons. Processing is considered complete on the
date the FR notice, announcing the final decision on the recognition, is submitted for
publication. Each application will be assigned a priority number, generally determined
by the date it is received. The assigned priorities may be changed for valid reasons,
including delays in obtaining information necessary to application processing, issues
unresolved by the applicant, and action or inaction by the applicant that causes delays in
processing. Examples include the applicant submitting major amendments or its failure
to meet deadlines for information requested by OSHA. The Director will maintain an
appropriate record of the receipt dates of all applications, amendments, and application-related correspondence. The Director will use these records to establish and maintain the
prioritization for pending applications, and will use this prioritization to establish a target
completion date and a schedule of processing activities for each application.
- Applications Not Accepted or Not Approved. An applicant may reapply at any time after
its application is not accepted or not approved (i.e., recognition is denied) by OSHA.
However, the Director may consider the causes leading to the non-acceptance or denial in
the evaluation of any future applications submitted by the applicant. Such evaluation will
be made without prejudice if the applicant withdraws its application prior to the effective
date of the rejection. The Director will retain one copy of the application, and other
pertinent documents, in the Case File and, in cases involving denial, in public files.
References in this Instruction to closing the Case File due to action or inaction by the
applicant constitutes a non-acceptance of the application by OSHA. Note: this procedure
also applies in those cases where an application is not approved by the Assistant
Secretary (see paragraph II.D in Chapter 5 below).
Chapter 4: On-site Review
- Purpose. This Chapter sets forth the procedures for performing an on-site review of
organizations seeking recognition, expansion, or renewal as an NRTL, and an audit of
NRTLs. The on-site review includes the pre-visit and the post-visit activities.
Note: when more than one assessor participates in a review, the term "lead assessor"
replaces the term "assessor." Also, where appropriate in Chapters 4 & 5, "NRTL" and
"auditor" replaces "applicant" and "assessor," respectively, when the review is an audit.
- Pre-visit Activities. The assessor develops a site-specific review plan based on the scope
of the recognition and the background of the applicant, the personnel capabilities required
to conduct the review, the duration of the review, and associated travel requirements. In
determining the scope of the on-site work, the assessor may consider third-party data
submitted by the applicant or NRTL.
- On-site Activities. The assessor:
- Opening Conference. Conducts the opening conference with the applicant's staff,
introducing team members, discussing the scope and objectives of the review, and
responding to questions from the applicant's staff concerning the review methods.
The site-specific agenda is modified as necessary based on the outcome of the
- Performance of Review Plan. Performs the site-specific review plan following the
procedures in Appendix E.
- Closing Conference. Conducts the closing conference with the applicant's staff,
presenting a summation of the findings and a copy of the preliminary Report on
Findings, if feasible, and responding to questions from the applicant's staff
concerning the findings. (For an audit, the auditor also identifies any deficiencies
that are a probable cause for revocation.) Where deficiencies are identified, upon
request, the assessor may informally suggest possible corrective actions. Such
suggestions should not be presented as exclusive solutions nor divulge
confidential information of another applicant or NRTL.
- Post-Visit Activities.
- Review Follow-up (Telephone Contact). The assessor contacts the applicant to
request any additional information, if some information is determined to be
insufficient after a review of the findings, and to discuss an appropriate deadline
for submitting its Written Response. The applicant's Written Response will
include a schedule for completing any corrective actions, narrative explanation
and supporting documentation to sufficiently address each area of deficiency
identified, and any other comments on the report that the applicant determines to
- Report on Findings and Written Response. The assessor:
- Finalizes the Report on Findings, marks it "Confidential," officially
submits it to the applicant with a cover letter requesting its Written
Response by a mutually-agreed-upon or other appropriate deadline, and
sends a copy to the Director and to each review team member. For an
audit, the auditor includes a statement on revocation if any deficiencies are
a probable cause of revocation.
- Begins to prepare the draft On-site Review Report following Appendix G.
- No Response (Applications). If the organization fails to submit its Written
Response by the response deadline or an approved extension of this deadline, the
application becomes inactive. The Director sends a final notification to the
applicant requesting the information within 30 days of the date of the notice. If
the applicant responds adequately within the 30 day period, the application is
assigned a lower priority and becomes active. If the applicant does not respond
adequately within the 30 days, the Director sends a letter notifying the applicant
that the application is not accepted, and the Case File is closed.
- Inadequate or No Response (Audit). If the NRTL does not adequately respond or
fails to submit its Written Response by the response deadline or an approved
extension of this deadline, the auditor contacts the NRTL to discuss the adequacy
of the response or the delay. The auditor also provides a final deadline for the
response after consulting the Director. After the auditor's discussion with the
NRTL, the Director notifies the NRTL in writing that OSHA is commencing the
process to revoke the NRTL's recognition. In this notification, the Director will
include the final deadline provided by the auditor or another deadline if more
Chapter 5: Evaluation and Approval
- Purpose. This Chapter sets forth the procedures for the evaluation and approval of
applications of organizations seeking recognition, expansion, or renewal as an NRTL.
- Evaluation and Approval Procedures.
- Preliminary Evaluation and Final Report. The assessor:
- Reviews the Written Response of the applicant and contacts the applicant
if necessary to resolve questions or obtain additional information.
- Completes the On-site Review Report following Appendix G, and
forwards the final report to the Director,.
- Final Evaluation. Program staff:
- Reviews the On-site Review Report and any other documentation, and
contacts the applicant if necessary to resolve questions or to obtain
- Makes the final evaluation on the application, and develops a
recommendation on the preliminary finding regarding the application
consistent with the approval criteria shown below. The Director may
require additional reviews of the applicant's facility(ies), if necessary,
before completing the final evaluation.
- Recommendation and Preliminary Finding. The Director recommends a positive
or negative finding on the application consistent with the approval criteria shown
- For a negative finding, Program staff notifies the applicant, and the
Director sends a letter to the applicant pursuant to Appendix A of 29 CFR
1910.7. Following the procedures described in "Revision of application"
under I.B.3, the applicant may provide additional information. Program
staff reviews this additional information, and the Director determines if the
additional information justifies changing to a positive finding.
- Program staff prepares the FR notice for the preliminary finding, as
required by 29 CFR 1910.7.
- The appropriate offices review and sign off on the FR notice. The
Assistant Secretary then reviews and approves the notice. During this
clearance process, Program staff modify the notice as needed.
- Program staff submits the notice for publication, sending a copy of the
document and the final on-site review report to the applicant prior to
publication. The Director sends a copy of the published notice to the
- Comment Period and Final Decision.
- Program staff reviews all timely comments, contacting the applicant or
other parties as needed to resolve significant issues raised by these
comments, and develops a recommendation regarding the recognition.
- The Director recommends approval or denial of the recognition, and
Program staff prepare the final FR notice.
- The appropriate offices follow the clearance procedures under paragraph D
of this Chapter, and for initial recognitions, the Assistant Secretary
approves a letter or other document of recognition, which the Director also
sends to the applicant. This letter or document sets forth the terms of
recognition, which include the scope of recognition, specific conditions
and limitations imposed by OSHA, general conditions required by
Appendix A of the Program regulations, and references to applicable
policies, directives, and requirements with which the NRTL must comply.
- If the Assistant Secretary does not approve the recognition, the Director
sends an explanatory letter to the applicant and closes the Case File.
- Approval Criteria. An application for recognition, expansion, or renewal may be
approved if OSHA determines that the following criteria are met:
- The application is both complete and adequate.
- The On-site Review Report or other written evaluation supports a
recommendation for a positive finding, that is, the applicant appears to have met
the requirements for recognition, expansion, or renewal.
- All significant issues raised during the comment period are resolved.
- Additional criteria for expansions and renewals:
- The NRTL has corrected all non-conformities from audits;
- The NRTL has not significantly or consistently violated its terms of
recognition during the previous 24 months; and
- The NRTL has resolved all significant issues concerning its recognition
raised, for example, in valid complaints or petitions, or which OSHA
otherwise determines to be valid.
Chapter 6: Post-Recognition
- Purpose. This Chapter sets forth policies and procedures for administering activities for
continuing the recognition of NRTLs.
- NRTL Program Policies. Each NRTL will comply with policies issued by OSHA that
revise or supplement the requirements or conditions of its recognition, including those in
- Schedule of Audits. Each year, the Director prepares a schedule of the on-site and
office audits planned for the year. These audits will be performed to ascertain
whether the NRTL continues to meet its terms of recognition.
- On-site Audits. OSHA will perform an on-site audit of each NRTL either
annually or on another frequency as determined by the Director. The audit will
generally be performed as prescribed by applicable portions of Chapters 4 and 5
of this Instruction.
- Office Audits. OSHA may perform an office audit of each NRTL not scheduled
for an annual on-site audit. For this purpose, the Director may annually request
each NRTL to respond to an appropriate questionnaire or other similar document
for purposes of updating relevant information and to provide documentation or
records to confirm conformance, in full or in part, to its terms of recognition.
- Unscheduled or Special Audits. OSHA may perform an unscheduled audit or
advance the scheduled date of an audit, when the Director determines that the
NRTL may have a serious violation of its terms of recognition. OSHA may also
perform special audits, such as auditing manufacturer's or other testing facilities
that the NRTL uses for purposes of testing and certifying its products.
- Fees. (Reserved)
- Complaints. Complaints received by OTPCA may be against a particular NRTL, the
products it certifies, or against the NRTL Program. Program staff reviews the complaint,
contacting the complainant or other parties as necessary, and reports to the Director. The
Director makes the determination as to the validity of the complaint, and may refer the
complaint to the Office of the Solicitor, if necessary.
- If the complaint is invalid, Program staff communicate the rationale to the
complainant (if known), and takes no further action.
- If the complaint appears to be valid, the Program staff contacts the subject NRTL
or other entity(ies), and takes appropriate steps to resolve the issues. When a
Written Response from the NRTL is appropriate, the Director will follow the
audit notification and deadline procedure in Chapter 4 of this Directive if the
NRTL submits an inadequate or no response. The Director or Program staff then
informs the complainant that the matter has been adequately resolved but does not
reveal the resolution to the complainant, and does not divulge the name of the
complainant or, if appropriate, the nature of the inquiry to the NRTL or to third
- Program staff document the resolution, and the Director assures that required
control measures are implemented.
- Voluntary Terminations and Revocations.
- Voluntary Termination. An NRTL may request a full or partial termination of its
recognition by sending a letter with appropriate information to the Director (see
II.D in Appendix A of the Program regulations). The request shall state the
effective date of the termination. The Director confirms the request and submits a
FR notice to terminate recognition by the effective date. Upon publication, the
Director will send a copy of the notice to the NRTL.
- Revocation. Upon receipt of information that an NRTL may have committed one
of the potential causes stated under II.E.1 in Appendix A of the Program
regulations, the Director shall review relevant documentation and determine if the
information appears to be valid.
- If invalid, the Director documents the decision and takes no further action.
If valid, the Director, with the concurrence of the Office of the Solicitor
and the Director of the Directorate of Technical Support, determines an
appropriate course of action, which may include:
For a revocation, the Director and appropriate personnel will follow the
process in II.E.2 through 5 in Appendix A. Notification of final deadlines
resulting from OSHA's audit of the NRTL, processing of valid
complaints, or similar actions taken by OSHA constitutes the first
notification under this process.
The Director will specify the form and content of the response required by
the NRTL for the notifications under the revocation process.
A revocation becomes effective 60 days from the date of the second
notification. After receiving the second notification, the NRTL must
- No action to revoke recognition
- Complete revocation of recognition
- Partial revocation of recognition
The Director may give public notice in the Federal Register regarding a
- Submit a written request for the hearing allowed, or
- Submit the required response by the 60-day deadline and include
appropriate documentation that demonstrate all deficiencies have been corrected. The Director will formally accept or reject the
NRTL's response. Rejection means the NRTL failed to adequately correct the deficiencies.

NRTL PROGRAM POLICIES
- Application Guidelines. The Application Guidelines for the NRTL Program are
incorporated by reference into this Instruction. These guidelines may be given to
applicants wishing recognition, expansion, or renewal of recognition as an NRTL. The
Director documents the current version of the guidelines in an OSHA internal
memorandum and distributes it as needed to the appropriate offices. The Director makes
the guidelines available in hard copy or diskette and on the web site for the NRTL
Program. See contact information and web site address in Chapter 1.
- Evaluation Criteria. Appendix A to 29 CFR 1910.7 requires the following: "In the
evaluation of the NRTLs, OSHA will use either consensus-based standards currently in
use nationally, or other standards or criteria which may be considered appropriate." In
compliance with this requirement, OSHA will use the specific criteria in the Detailed
Application Information/Evaluation Criteria (DAI/EC) part of the Application Guidelines,
to evaluate whether an applicant meets or an NRTL continues to meet the requirements
for an NRTL in 29 CFR 1910.7. The general basis for these criteria is shown in
Appendix F. OSHA may use other or alternative criteria that it deems necessary due to
specific circumstances of an application, facility, organization, or other pertinent factors.
In the event of a difference between an OSHA-specific criterion or policy, and any
clauses of national or international standards or guides, the applicable OSHA-specific criterion or policy will control.
An applicant meeting the pertinent detailed criteria of the DAI/EC meets the
corresponding recognition requirement in 29 CFR 1910.7(b) or has the capability to use
the corresponding supplemental program. An applicant not fully meeting the detailed
criteria for one or more evaluation categories in the DAI/EC must submit sufficient
information and detail to clearly demonstrate how it otherwise meets the corresponding
- NRTL Follow-up Inspections at Manufacturing Facilities. An NRTL must provide, to the
extent needed for a particular product it has certified, inspection of "the run of production
of such items at factories for product evaluation purposes to assure conformance with the
test standards." As part of complying with this requirement, an NRTL must physically
inspect each manufacturing facility of products it has certified to ensure that the
manufacturer continues to produce these products as certified by the NRTL. The NRTL
must inspect each such facility and each product it has certified at the minimum
frequencies specified below. The NRTL must use qualified personnel or representatives
to perform each inspection and, when appropriate, must perform unannounced
inspections or give minimal notice. Inspections must involve an actual visit to the facility
and not just a review of product plans, photographs, or similar items. Inspections at non-manufacturing facilities, if properly controlled, may supplement but cannot replace the
minimum number of inspections for manufacturing facilities required in this policy. [For
purposes of this policy, manufacturing facility is an establishment used for fabricating or
assembling a product (model or item) covered under the NRTL's agreement for
certification services. A facility that primarily distributes products, such as a "single
point distribution" site, or that makes final, but minimal, assembly of products is not a
manufacturing facility. Also, for purposes of this policy, the terms inspect and inspection
refer to an audit of a manufacturing facility by the NRTL.]
- Frequency of Inspections. An NRTL must perform a greater frequency of
inspections at facilities where greater safety concerns exist regarding the
manufacture of products certified by the NRTL. At a minimum, such concerns
exist under any of the following situations:
- The products are intended for use in hazardous locations;
- The NRTL has evidence or suspects that the manufacturer has not been
producing a product in conformance with the product safety requirements
or maintaining appropriate controls over its production process at a
- The facility is in a region where mislabeling or counterfeit labeling occurs
frequently and there is a question about the manufacturer's ability to
control and mark products correctly;
- The NRTL has evidence or suspects that the manufacturer is not using or
controlling the NRTL's certification mark(s) correctly; or
- The NRTL has evidence or suspects that safety concerns exists concerning
The NRTL must perform these inspections to the extent needed to provide
assurance that the product is manufactured as certified. In situations involving the
above safety concerns, the NRTL must perform no fewer than four (4) inspections
per year at these facilities.
An NRTL may perform the inspections less frequently at any facilities where the
above safety concerns or similar situations do not exist. However, the
manufacturer in such situations must consistently demonstrate ongoing quality
management and control programs, and effectiveness in meeting the product
safety requirements. In such cases, the NRTL must perform no fewer than two (2)
inspections per year at these facilities.
While its certification remains in effect, an NRTL must inspect each certified
product to the extent needed for that particular product but not less frequently than
once every two years. In performing this inspection, the NRTL may use the
inspection of a product at a manufacturing facility to meet the inspection
requirements for similar products manufactured at this specific facility. For
purposes of this policy, similar products are products grouped in a category based
on the same or equivalent product manufacturing characteristics or technical
- Policies and Procedures for Inspections. The NRTL must perform its inspections
consistent with applicable NRTL Program policies and according to its follow-up
inspection program. This program will include written procedures in sufficient
detail that identify the specific activities the NRTL performs during inspections
and how the NRTL addresses the various situations and options identified in this
policy. The follow-up inspection program must be part of the official
documentation of the NRTL, that is, part of its operating procedures or quality
assurance program. The NRTL's inspection program must clearly and
consistently justify the inspection frequency, and changes to this frequency, that
the NRTL has adopted for a facility or for a particular type of product. The NRTL's procedures must address products having seasonal or non regular
production cycles. In addition, the NRTL must address any concerns that can
exist with production lines that are intermittent. The procedures must also
adequately address reinstatement of inspections when the NRTL confirms that a
facility, subject to regular inspections, does not have production or stock of
The NRTL will determine the specific activities to undertake in performing each
inspection and will document these activities. However, follow-up inspections
activities (but not necessarily every inspection) will at least include or address the
- Physical examination of the product being inspected against an inspection
document that describes the product;
- Sample selection for subsequent countercheck testing, if appropriate;
- Verification of in-process and final testing that is required by the test
standard or that is regularly conducted at the factory as a part of the
manufacturer's quality management system;
- Confirming the use of approved components;
- Monitoring use and control of the NRTL's mark; and
- Calibration of equipment used in testing.
In performing an inspection at a manufacturing facility, an NRTL may perform
multiple activities. Such activities include auditing more than one product,
performing a quality audit to ISO 9000 or other standard, qualification audits for
programs that OSHA has recognized (see March 9, 1995 Federal Register notice),
or any combination of activities with similar purposes. For example, the NRTL
may include a quality audit of a manufacturing site as part of an inspection it
performs for this site. For such inspections, the NRTL must use inspectors
qualified in performing all activities undertaken. ISO or similar audits or activities
may not replace the inspections required by this policy.
In determining the areas to review during an on-site visit (i.e., records, quality
control, calibrations), an NRTL can take into consideration inspections performed
by others that are not subcontractors or agents of the NRTL. However, use of
such inspection data generated by others does not relieve the NRTL from its
responsibilities for performing the required inspections. An NRTL that has
received recognition for Program 9 may use others acting as subcontractors or
agents of the NRTL to perform follow-up inspections, unless such recognition
limits this use.
- Programs Allowed under March 9, 1995 FR Notice (60 FR 12980, 3/9/95)
- Content of programs. Nine programs are described in the March 9, 1995 FR
notice. See list of names of programs in Chapter 2. With the exception of
program #1, an applicant or NRTL must make a specific request to include a
program within its scope of recognition. Each program provides alternatives for
accomplishing portions of the product certifications. The term "program"
encompasses all the policies and procedures that enable compliance with all the
criteria listed for each program. A program is also referred to as a "procedure" in
the March 9 notice. Recognition for a program is contingent on the applicant or
NRTL adequately meeting all the criteria for a program. Each NRTL is
automatically recognized for program #1, which is called the "Basic Procedure",
when it is first recognized. Applicants should apply for program #9 which allows
for the NRTL to subcontract for services other then testing and evaluation. Some
of the subcontracted services that are covered under program #9 include
calibration, follow-up inspections, equipment maintenance, and security.
- Use of Programs. With the exception of Program 1, to use any of the programs of
the March 9 notice, the NRTL must meet the criteria for the particular program(s)
- Be recognized to perform the tests and evaluations before it can accept
such services from other organizations, except for unique or special testing
- Use assessors having qualifications consistent with the competence
requirements of the appropriate national standards and international guides
to qualify organizations.
- Ensure that all aspects of certification work performed by others, including
participants, locations of testing, witnessing, and evaluations, are
identified in the NRTL and client records and reports.
- Correction of program descriptions. The term "program" replaces the term
"procedure" when referring to the activities, numbered 1-9, described on pages
12982 through 12985 of the FR notice. In addition, the following corrections are
made to the text for each of the following programs:
- Program 3 - Acceptance of Product Evaluations From Independent
Organizations, Other Than NRTLs. In the following statement, the term
"Procedure 1" is changed to "Program 2," to read as follows: "An NRTL
may accept product evaluations prepared by an independent organization
provided the following criteria, in addition to the requirements in Program
2, are complied with:"
- Program 5 - Acceptance of Testing Data From Non-Independent
Organizations. In the following statement, the term "Procedure 1" is
changed to "Program 2," to read as follows: "An NRTL may accept testing
conducted by a non-independent organization provided the following
criteria are complied with, in addition to the requirements in Program 2,
with the exception for the need to document the independence of the
- Program 6 - Acceptance of Evaluation Data From Non-Independent
Organizations (Requiring NRTL Review Prior to Marketing). In the
following statement, the term "Procedures 1, 2, and 4" is changed to
"Programs 2, 3, and 5," to read as follows: "Except for the requirement for
independence, the specific program criteria in Programs 2, 3, and 5 shall
apply to product evaluations by nonindependent organizations."
- Program 7 - Acceptance of Continued Certification After Minor Product
Modifications by the Manufacturer. In the following statement, the term
"Procedures 1, 2, 4, and 5" is changed to "Programs 2, 3, 5, and 6," to read
as follows: "An NRTL may accept minor product modifications from a
manufacturer without requiring recertification provided the following
criteria, as well as the criteria in Programs 2, 3, 5, and 6(except for the
requirements for independence), are complied with:"
- Independence of a Nationally Recognized Testing Laboratory. To comply with 29 CFR
1910.7(b)(3), an NRTL must be free from commercial, financial and other pressures that
could compromise the results of its testing and certification processes. [For the purposes
of this policy, an NRTL means an NRTL applicant or an existing NRTL.] The NRTL
must be free of these pressures from employers that are major users of equipment or
materials ("products") the NRTL may test and certify, if the employers are subject to the
tested equipment requirements. [In general, the user in question is not the NRTL
organization itself. Also, the "tested equipment requirements" are generally found in 29
CFR Part 1910.] In addition, the NRTL must also be free of these pressures from
manufacturers or vendors ("suppliers") of these products. If the NRTL is not free of
these pressures, it would not meet the requirements specified under 29 CFR 1910.7(b)(3),
and would not obtain or could not retain its recognition unless it complies with the
conditions that OSHA may impose. Such conditions shall be consistent with this policy.
In general, the conditions may restrict the suppliers for whom the NRTL may test and
certify products, or restrict the type of products the NRTL may test and certify.
These pressures are presumed to exist if there is a substantial relationship between the
NRTL and a supplier or major user of products that must be certified which could
compromise the objectivity and impartiality in determining the results of its testing and
certification processes. [Substantial, for the purposes of this policy, means of such a
nature and extent as to exert undue influence on the testing and certification processes.]
This presumption may be rebutted by the NRTL provided it can present clear and
convincing information to the contrary.
Such a relationship includes, but is not limited to, the following:
- The NRTL is a supplier or major user of products that an NRTL must certify, or is
organizationally affiliated with such a supplier or major user;
- The NRTL significantly finances, invests in, sells product design, similar services
or products to a supplier or major user;
- The NRTL is owned in excess of two percent (2%) by a supplier or major user, or
their major owners;
- The NRTL receives significant financing from a supplier or major user, or their
major owners; or
- A person holding a substantial position with the NRTL has a significant financial
interest in a supplier or major user, or is a director or key personnel of either.
The NRTL must have policies and procedures in place to ensure that none of the
relationships described above or similar relationships exists with respect to suppliers or
major users of products. In addition, the NRTL must submit a statement to OSHA
certifying that it complies and will continue to comply with this policy on independence,
and it will fully comply with any conditions imposed by OSHA.
- Quality Assurance and Internal Audits. An NRTL must have and must follow written
quality assurance programs to meet the "capability" requirement of 29 CFR 1910.7. As
part of meeting this requirement, the NRTL must fulfill all of the following:
- Have one or more quality manuals covering its testing and certification activities.
Each manual should be consistent with ISO 10013, and should meet the
applicable portions of the versions of Guide 25 and 65 referenced in Appendix F.
ISO publications may be obtained from the American National Standards Institute
(ANSI) or from the International Organization for Standardization (ISO).
- Perform internal audits of its testing and certification processes at least once per
year. The NRTL's internal audits should be planned and performed in
accordance with ISO 10011-1:1990(E), and any additional requirements contained
in clause 4.17 of ISO 9000-2:1997(E). In addition, an NRTL's internal audit
reporting must include, at a minimum:

1910.7, an NRTL must have and must follow written standard processing procedures
related to product testing, evaluation, certification, training, and other processes that are
or will be used in operating as an NRTL. The NRTL must ensure it:
- Has procedures for processing a certification application that identify the steps for
the application, administrative/technical processing of the investigation in
chronological order, personnel responsible for each stage of the process, and
records maintained at various steps of the process;
- Selects the product standard for certification, and has procedures that identify the
steps and criteria for selection, personnel responsible for decision (who are
experienced in the product area), manner of resolving disagreements concerning
the applicability of a standard, and manner of handling products covered by two
or more standards; and
- Has procedures for developing and maintaining processing procedures that

demonstrate control in its operating policies and procedures and quality assurance
program documentation. The NRTL may use laboratory sites meeting these criteria but
not formally recognized by OSHA, including any foreign-based sites, provided they are
used only to conduct testing. An NRTL may use these non-recognized sites, referred to
as "satellite facilities," only if OSHA has determined that the NRTL maintains proper
controls over the use of these sites. OSHA must recognize any site before an NRTL may
use it to:
- Authorize the use of the NRTL's mark for the product standards for which the
NRTL has been recognized;
- Maintain primary product test and evaluation files;
- House the personnel in charge of any of the programs listed under the March 9,
1995, Federal Register (FR) notice; or
- House personnel whose expertise is used in the initial qualification of participants
in any of the program options available under the March 9, 1995, FR notice.
- Records. An NRTL must maintain proper records of its activities related to testing and
certification as an NRTL, as part of meeting the "capability" and "control procedures"
requirements of 29 CFR 1910.7. In maintaining proper records, an NRTL must follow:
- Written policies and procedures for test standards distribution & control that:

- Specifies how to correct administrative discrepancies with reports after
they are issued, and how to correct or modify information on a completed
- Documents how each certification procedure was applied, including
- Follow-up Inspection Program. An NRTL must provide "inspections" of manufacturing
facilities, as required under 29 CFR 1910.7(b)(2). As part of meeting this requirement, an
NRTL must meet the criteria in paragraph III of this Appendix, and must:
- Perform initial assessment of the manufacturing facility, manufacturer's quality
control system, records and documents, and evaluations and tests required by the
Standard, following written procedures.
- Perform follow-up inspections following written procedures that should:
- Identify who conducts the periodic follow-up inspections;
- Ensure agents used for follow-up inspections, if any, have the facilities
and qualified staff for adequate surveillance; and
- Ensure results of the manufacturer's surveillance is routinely reported to
the applicant and maintained in a file.

production for independent testing;
- Covenants from the client to observe and comply with the applicable
- Controls to prevent the client from releasing the products resulting from
changes (in the product, process or quality management system) until the
laboratory has notified the client;
- Provision(s) for unobstructed access to the manufacturing premises
without prior notification;
- Provision that the product will be produced to the same specifications as
the sample submitted for initial testing; and
- Controls to ensure that all quality management system and production
records will be open and readily available for inspection by the laboratory.
- Effective Reporting - An NRTL must "maintain effective procedures" for producing
credible "findings and reports," as required under 29 CFR 1910.7(b)(4). As part of
meeting this requirement, an NRTL must have and must follow written procedures for:
- Preparing technical reports that:
- Identify person(s) responsible for preparation, technical content review,
- Clear and organized report format that facilitates data extraction;
- Sufficient information to permit repetition of tests;
- Identifies the appropriate test and evaluation procedures; and
- Identifies person(s) who authorize revisions or technical corrections.
- Report distribution that ensure that copies of tests report are limited for the sake
of confidentiality, and that copies of test reports are sent to everyone who needs
- Allowable and Withdrawn Test Standards.
- A test standard that meets the criteria for approval in Appendix D, and that is
issued by the American National Standards Institute (ANSI), is an appropriate test
standard as prescribed by 29 CFR 1910.7(c)(4). An NRTL that is approved for a
particular test standard may use either the latest proprietary version of the test
standard or the latest ANSI version of that standard, regardless of whether it is
currently recognized for the proprietary or ANSI version.
- A test standard withdrawn by a standards organization is no longer an appropriate
test standard. OSHA will de-recognize withdrawn test standards by issuing a
correction notice in the Federal Register for all NRTLs recognized for the
standards. An NRTL may request recognition for a comparable standard, and
OSHA will note the substitution in the correction notice if it determines the
standard is appropriate and comparable.
- Certification Mark(s) and Listing Program. An NRTL must implement "control
procedures for identifying" products it has certified, as prescribed by 29 CFR
1910.7(b)(2). As part of meeting this requirement, an NRTL must have the following:
- A registered certification mark(s), as evidenced by a certificate of registration
issued by the U.S. Patent and Trademark Office (USPTO) or by a national or
international body under a registration system that requires ownership of the
mark(s) and that is equivalent to the USPTO system of registration. An applicant
for initial recognition must submit, at the time of application, evidence of such
registration or, if not registered, evidence of application for registration of its
mark(s) with the USPTO and, within a reasonable time after applying for
recognition, evidence of registration with the USPTO. In addition, the NRTL
- Use only this certification mark(s) for its NRTL activities, and
- Ensure this certification mark(s) is applied to each unit, or if not feasible,
to the smallest package of the products it has certified; and
- A listing and labeling program that includes:
- Procedures and resources to properly control its certification mark;
- Procedures and resources to monitor advertisements, catalogues and
brochures for incorrect references or misleading use of its certification,
and to take appropriate corrective actions; and
- Procedures and resources to take corrective action when its mark is
- Testing Procedures. An NRTL must have and must follow adequate "written testing
procedures" in order to meet the capability requirement of 29 CFR 1910.7. To meet this
requirement, the NRTL must have all the following:

the test; and
- Ambient test conditions and test results.
- Written procedures for developing and maintaining testing methods and
- Identify person(s) responsible for developing, reviewing and maintaining
- Specify frequency of review by management;
- Ensure consistency with recognized standards, and deviations that still
assure the product conforms with the standard; and
- Ensure modifications are reviewed by personnel who are familiar with the
- Calibration Traceability. An NRTL must have an adequate "calibration program" in
order to meet the capability requirement of 29 CFR 1910.7. As part of meeting this
requirement, an NRTL must have and must follow written procedures that address
calibrations and reference standards or materials, and that ensure their traceability to the
appropriate standards maintained by the U.S. National Institute of Standards and
Technology (NIST), or if in a foreign country, to equivalent standards or materials
maintained by a nationally or internationally recognized body.
- Definition of Foreign-based Testing Agency or Organization. Appendix A to 29 CFR
1910.7 requires that OSHA consider certain policies of the foreign government in
determining the eligibility of a foreign-based testing agency or organization [collectively,
organization] that applies for recognition as an NRTL. For the purpose of this
requirement, an organization is foreign-based if (1) the legal entity in which it conducts
business is incorporated or otherwise legally registered in a country other than the United
States (including its territories) ("US"), or (2) it is headquartered or has its main office or
place of business outside the US, even though the legal entity in which it conducts
business may be incorporated or otherwise legally registered in the US.
