Notice of Expansion Application

The Occupational Safety and Health Administration (OSHA) is providing notice that Underwriters Laboratories, Inc. (UL), applied for expansion of its current recognition as a Nationally Recognized Testing Laboratory (NRTL). UL's expansion request covers the use of additional test standards.

OSHA recognition of an NRTL signifies that the organization meets the legal requirements specified in 29 CFR 1910.7. Recognition is an acknowledgment that the organization can perform independent safety testing and certification of the specific products covered within its scope of recognition, and is not a delegation or grant of government authority. As a result of recognition, employers may use products approved by the NRTL to meet OSHA standards that require product testing and certification.

The Agency processes applications by an NRTL for initial recognition, or for an expansion or renewal of this recognition, following requirements in Appendix A to 29 CFR 1910.7. This appendix requires that the Agency publish two notices in the Federal Register in processing an application. In the first notice, OSHA announces the application and provides its preliminary finding, and, in the second notice, the Agency provides its final decision on the application. These notices set forth the NRTL's scope of recognition or modifications of that scope. OSHA maintains an informational Web page for each NRTL that details its scope of recognition. These pages can be accessed from the Web site at​dts/​otpca/​nrtl/​index.html. Each NRTL's scope of recognition has three elements: (1) Type of products the NRTL may test, with each type specified by its applicable test standard; (2) the recognized site(s) that has/have the technical capability to perform the testing and certification activities for test standards within the NRTL's scope; and (3) the supplemental program(s) that the NRTL may use, each of which allows the NRTL to rely on other parties to perform activities necessary for product testing and certification.

General Background on the Application

UL submitted an application, dated February 20, 2008, as an amendment to its application for renewal of recognition. (Ex. 2—UL expansion application dated 2/20/2008.) This amendment requested an expansion of recognition to add 98 standards [1] to UL's scope and to delete several test standards from its scope. The NRTL Program staff determined that 49 of the requested standards are “appropriate test standards” within the meaning of 29 CFR 1910.7(c). UL later modified its request to reduce the number of the appropriate standards to 35. (Ex. 3—UL amended expansion application dated 2/16/2010.)

In connection with this request, NRTL Program staff did not perform any onsite review of UL's recognized sites. The staff only performed a comparability Start Printed Page 21665analysis,[2] which determined that UL has the capabilities to perform the testing to the 35 standards, (see the list below). As a result, the Agency would approve these 35 test standards for the expansion.

UL seeks expansion of its recognition for testing and certification of products to the following test standards: [3]

IEEE C37.20.4 Indoor AC Switches (1 kV-38 kV) for Use in Metal-Enclosed Switchgear a

a Recognition for this standard does not apply to testing and certification of equipment or materials used in installations that are excluded from the provisions of subpart S in 29 CFR 1910 by section 1910.302(a)(2).

b Recognition for this standard is limited to testing and certification of products used within recreational vehicles and mobile homes.

c Recognition of this standard is limited to testing and certification of the electrical devices falling within the standard's scope.

OSHA's recognition of UL, or any NRTL, for a particular test standard is limited to equipment or materials (i.e., products) for which OSHA standards require third-party testing and certification before use in the workplace. Consequently, if a test standard also covers any product for which OSHA does not require such testing and certification, an NRTL's scope of recognition does not include that product.

The test standards listed above may be approved as American National Standards by the American National Standards Institute (ANSI). However, for convenience, we may use the designation of the standards-developing organization for the standard as opposed to the ANSI designation. Under the NRTL Program's policy, any NRTL recognized for a particular test standard may use either the proprietary version of the test standard or the ANSI version of that standard. Contact ANSI to determine whether a test standard is currently ANSI approved.

Voluntary Modification of Scope

UL also requested to modify its scope of recognition by deleting the following two test standards:

ANSI/IEEE C37.60 Overhead, Pad-Mounted, Dry-Vault, and Submersible Automatic Circuit Reclosers and Interrupters for AC Systems

ANSI/UL 632 Electrically Actuated Transmitters

UL originally applied for UL 486A (“Wire Connectors and Soldering Lugs for Use With Copper Conductors”) (see Ex. 2), but then excluded this standard when it later modified its request (see Ex. 3). However, as of the date of this Federal Register notice, UL 486A has been withdrawn from the list of published standards by the standards-developing organization. As a result, OSHA is deleting this standard from UL's NRTL scope, as well as the scopes of NRTLs recognized previously by OSHA for it. OSHA periodically publishes notices to make such deletions (see, for example, 74 FR 47026, September 14, 2009).

Issue Regarding NFPA Standards

UL requested that OSHA include the following four standards, issued by the National Fire Protection Association (NFPA), in UL's recognition-expansion application:

NFPA 16 Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems

NFPA 17A Standard for Wet Chemical Extinguishing Systems

NFPA 2001 Standard on Clean Agent Fire Extinguishing Systems

NFPA 2010 Standard for Fixed Aerosol Fire-Extinguishing Systems

However, these test standards are not appropriate for recognition because the standards primarily cover installation, use, and maintenance of a system or its elements, instead of product-safety testing. Therefore, OSHA is not including these test standards in UL's expanded scope of recognition.

OSHA also notes that it currently recognizes several NRTLs for NFPA 16, as well as for four similar NFPA Start Printed Page 21666standards, none of which appears to cover primarily product-safety testing. These four standards are:

ANSI/NFPA 11 Low-, Medium-, and High-Expansion Foam

ANSI/NFPA 12 Carbon Dioxide Extinguishing Systems

ANSI/NFPA 12A Halon 1301 Fire Extinguishing Systems

ANSI/NFPA 17 Dry Chemical Extinguishing Systems

Accordingly, OSHA is proposing to remove NFPA 16 and the four similar test standards from these NRTLs' scopes of recognition. Before doing so, OSHA requests comment on whether this action would have adverse impact on the requirements for NRTL certification specified for products under its standards (such as preventing NRTLs from certifying fire-extinguishing agents or products). If commenters believe that adverse impact would occur, OSHA requests that they comment on whether the Agency should continue allowing NRTLs to use these test standards until it identifies appropriate standards for certifying the affected products.[4] If no adverse impacts would occur, OSHA is proposing to delete NFPA 16 and the four similar test standards from the scopes of the affected NRTLs. OSHA will issue its decision regarding these test standards in the subsequent Federal Register notice announcing the results of UL's expansion request.

Preliminary Finding on the Application

UL submitted an acceptable request for expansion of its recognition as an NRTL. OSHA's review of the application file and other pertinent documents indicates that UL can meet the requirements, as prescribed by 29 CFR 1910.7, for an expansion of its recognition to include the additional test standards listed above. This preliminary finding does not constitute an interim or temporary approval of the application.

OSHA welcomes public comments, in sufficient detail, as to whether UL meets the requirements of 29 CFR 1910.7 for expansion of its recognition as an NRTL. Comments should consist of pertinent written documents and exhibits. Commenters needing more time to comment must submit a request, in writing, stating the reasons for the request. OSHA must receive the written request for an extension by the due date for comments. OSHA will limit any extension to 15 days unless the requester justifies a longer period. OSHA may deny a request for an extension if it is not adequately justified. To obtain or review copies of UL's request and other pertinent documents, and all submitted comments, as received, contact the Docket Office, Room N-2625, Occupational Safety and Health Administration, U.S. Department of Labor, at the above address; these materials also are available online at under Docket No. OSHA-2009-0025.

The NRTL Program staff will review all timely comments and, after addressing the issues raised by these comments, will recommend whether to grant UL's expansion request. The Assistant Secretary will make the final decision on granting the request, and, in making this decision, may undertake other proceedings that are prescribed in Appendix A to 29 CFR 1910.7. OSHA will publish a public notice of this final decision in the Federal Register.
