SUPPLEMENTARY INFORMATION:

Notice of Final Decision

The Occupational Safety and Health Administration (OSHA) hereby gives notice of the renewal and expansion of recognition of Underwriters Laboratories Inc. (UL) as a Nationally Recognized Testing Laboratory (NRTL). UL's expansion covers the use of two additional sites and additional test standards. The NRTL's scope of recognition may be found in the following OSHA informational web page: http://www.osha.gov/dts/otpca/nrtl/ul.html. The information on this page will be updated in the very near future to include the recognitions granted in this notice.

OSHA recognition of an NRTL signifies that the organization has met the legal requirements in Section 1910.7 of Title 29, Code of Federal Regulations (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 "properly certified" by the NRTL to meet OSHA standards that require testing and certification.

The Agency processes applications by an NRTL for initial recognition or for 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. We maintain an informational web page for each NRTL, which details its scope of recognition. These pages can be accessed from our web site at http://www.osha.gov/dts/otpca/nrtl/index.html.

When OSHA published its regulations for the NRTL Program at 29 CFR 1910.7, it temporarily recognized UL as a nationally recognized testing laboratory for a five year period from June 13, 1988, through June 13, 1993 (see Appendix A to 1910.7). In Appendix A, OSHA also required that UL apply for renewal of its OSHA recognition at the end of this temporary period. UL did apply for the renewal, which OSHA announced in March 29, 1995 (60 FR 16171). In its renewal application, UL stated that it was founded in 1894. It also stated that its "principal activity is investigating the safety of many kinds of products, including electrical and electronic equipment and products," and a number of other products and systems. The Agency granted UL's renewal for a period of five years ending on June 29, 2000.

Appendix A to 29 CFR 1910.7 stipulates that the period of recognition of an NRTL is five years and that an NRTL may renew its recognition by applying not less than nine months, nor more than one year, before the expiration date of its current recognition. UL submitted a request, dated September 17, 1999 (see Exhibit 23), to renew its recognition, within the time allotted, and UL retains its recognition pending OSHA's final decision in this renewal process. UL's existing scope of recognition consists of the facilities already recognized and the supplemental programs, as listed below, and the test standards listed under Renewal of Recognition below.

UL also submitted requests, dated June 6, and October 5, 2000 (see Exhibits 23-1 and 23-2), to expand its recognition to include the two additional sites listed below. Moreover, UL submitted a request, dated March 29, 2001 (see Exhibit 23-3), to expand its recognition to include 142 additional test standards. The OSHA NRTL Program staff determined that 64 of those test standards, listed below under Expansion of Recognition, will be included in UL's scope of recognition. We could not approve the remaining test standards for various reasons, primarily because we determined that they did not meet our approval criteria or our requirements for "appropriate test standards," within the meaning of 29 CFR 1910.7(c). The staff makes such determinations in processing applications from any NRTL.

In processing UL's renewal request, OSHA NRTL Program staff performed an on-site review of UL's Northbrook facility on July 16-20, 2001. In processing UL's expansion requests to include the additional sites, OSHA NRTL Program staff performed an on-site review of the facility in Ontario on January 22-25, 2001, and a similar review of the facility in Tokyo on March 12-15, 2001. In the on-site review reports (see Exhibits 24, 24-1, and 24-2), the program staff recommended a "positive finding," which means a positive recommendation to the Assistant Secretary regarding the applications.

OSHA published the required notice in the Federal Register on March 18, 2002 (67 FR 12054), to announce UL's renewal and expansion requests. This notice included a preliminary finding that UL could meet the requirements in 29 CFR 1910.7 for renewal and expansion of its recognition and invited public comment by April 2, 2002. OSHA received no comments concerning this notice.

The previous notice published by OSHA for UL's recognition covered an expansion of recognition to include additional sites, which became effective on December 7, 1999 (64 FR 68389). The other Federal Register notices related to UL's recognition that OSHA has published since UL's previous renewal addressed an expansion for additional standards, which OSHA announced on November 21, 1997 (62 FR 62359) and granted on June 24, 1999 (64 FR 33913). The renewal incorporates all of these recognitions granted to UL, including the expansion being granted in this notice.

You may obtain or review copies of all public documents pertaining to the UL applications by contacting the Docket Office, Occupational Safety and Health Administration, U.S. Department of Labor, 200 Constitution Avenue, NW, Room N2625, Washington, DC 20210. You should refer to Docket No. NRTL4-93, the permanent record of public information on the UL recognition.

UL Japan Co., Ltd., Shimbashi Ekimae Bldg. -- 1 Gohkan, 4th floor, Room 402, 2-20-15 Shimbashi Minato Ku, Tokyo 105-0004, Japan

Programs and Procedures

The renewal of recognition includes UL's continued use of the following supplemental programs and procedures based upon the criteria detailed in the March 9, 1995 Federal Register notice (60 FR 12980, 3/9/95). This notice lists nine (9) programs and procedures (collectively, programs), eight of which an NRTL may use to control and audit, but not actually to generate, the data relied upon for product certification. An 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. OSHA has already recognized UL for these programs. See http://www.osha.gov/dts/otpca/nrtl/ul.html.

Program 2: Acceptance of testing data from independent organizations, other than NRTLs.

Program 3: Acceptance of product evaluations from independent organizations, other than NRTLs.

Program 4: Acceptance of witnessed testing data.

Program 5: Acceptance of testing data from non-independent organizations.

Program 6: Acceptance of evaluation data from non-independent organizations (requiring NRTL review prior to marketing).

Program 7: Acceptance of continued certification following minor modifications by the client.

Program 8: Acceptance of product evaluations from organizations that function as part of the International Electrotechnical Commission Certification Body (IEC-CB) Scheme.

Program 9: Acceptance of services other than testing or evaluation performed by subcontractors or agents.

OSHA developed these programs to limit how an NRTL may perform certain aspects of its work and to permit the activities covered under a program only when the NRTL meets certain criteria. In this sense, they are special conditions that the Agency places on an NRTL's recognition. OSHA does not consider these programs in determining whether an NRTL meets the requirements for recognition under 29 CFR 1910.7. However, these programs help to define the scope of that recognition.

Final Decision and Order

The NRTL Program staff has examined the applications, the assessor's reports, and other pertinent information. Based upon this examination and the assessor's recommendations, OSHA finds that Underwriters Laboratories Inc. has met the requirements of 29 CFR 1910.7 for renewal and expansion of its NRTL recognition. The renewal and expansion apply to the sites listed above. In addition, the renewal and expansion cover the test standards listed below and are subject to the limitations and conditions, also listed below. Pursuant to the authority in 29 CFR 1910.7, OSHA hereby renews and expands the recognition of UL, subject to these limitations and conditions.

Limitations

Renewal of Recognition

OSHA limits the renewal of recognition of UL to the 10 sites listed above. In addition, similar to other NRTLs that operate multiple sites, the Agency's recognition of any UL testing site is limited to performing testing to the test standards for which OSHA has recognized UL and for which the site has the proper capability and control programs. OSHA further limits the renewal of recognition of UL to testing and certification of products for demonstration of conformance to the following 638 test standards, which OSHA has previously recognized for UL. Except as explained below (see paragraph immediately following listing of standards), all these standards are "appropriate," within the meaning of 29 CFR 1910.7(c).

Restrictions/Limitations on Recognition

⁽¹⁾ These standards are approved for equipment or materials intended for use in commercial and industrial power system applications. These standards are not approved for equipment or materials intended for use in installations that are excluded from the provisions of Subpart S in 29 CFR 1910 by Section 1910.302(a)(2).

Note: Testing and certification of gas operated equipment is limited to equipment for use with "liquefied petroleum gas" ("LPG" or "LP-Gas")

At the time of preparation of the preliminary notice, some of the test standards for which OSHA currently recognizes UL, and which are listed above, have been withdrawn or replaced by the standards developing organization. Under OSHA policy regarding such withdrawn or replaced test standards, OSHA can no longer recognize the NRTL for the test standards, but the NRTL may request recognition for comparable test standards, i.e., other appropriate test standards covering similar types of product testing. However, a number of other NRTLs also are recognized for these withdrawn or replaced standards. As a result, OSHA will publish a separate notice to make the appropriate substitutions for UL and the other NRTLs that were recognized for these standards. However, see footnote ⁽³⁾ at the end of list of standards under the Expansion of Recognition section below.

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, an NRTL's scope of recognition excludes any product(s) falling within the scope of a test standard for which OSHA has no NRTL testing and certification requirements.

Many of the Underwriters Laboratories (UL) test standards listed above, and listed later in this notice, are approved as American National Standards by the American National Standards Institute (ANSI). However, for convenience in compiling the list, we use the designation of the standards developing organization (e.g., UL 1004) for the standard, as opposed to the ANSI designation (e.g., ANSI/UL 1004). Under our procedures, an NRTL recognized for an ANSI-approved 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. Contact ANSI or the ANSI web site (http://www.ansi.org) and click "NSSN" to find out whether or not a test standard is currently ANSI-approved.

Expansion of Recognition

OSHA limits the expansion of recognition to the two additional sites located in Tokyo, Japan, and in Ontario, Canada, as listed earlier in this notice. These sites are wholly owned or controlled by UL. As stated under the renewal section above, the Agency's recognition of any UL testing site is limited to performing testing to the test standards for which OSHA has recognized UL and for which the site has the proper capability and control programs. In addition, OSHA would permit the two sites to use all eight of the "supplemental" programs, listed earlier in this notice, as do the 10 sites already recognized.

OSHA further limits the expansion to testing and certification of products for demonstration of conformance to the following 64 test standards, and OSHA has determined the standards are "appropriate," within the meaning of 29 CFR 1910.7(c).

⁽²⁾ This standard is approved for testing and certification of products for use within recreational vehicles and mobile homes.

⁽³⁾ This standard replaces UL 1950. Upon publication of this final notice, the web page of all other NRTLs currently recognized for UL 1950 also will be updated to include UL 60950, due to earlier requests received from some of these other NRTLs for recognition of UL 60950.

Conditions

Underwriters Laboratories Inc. must also abide by the following conditions of the recognition, in addition to those already required by 29 CFR 1910.7:

OSHA must be allowed access to the UL facilities and records for purposes of ascertaining continuing compliance with the terms of its recognition and to investigate as OSHA deems necessary;

If UL has reason to doubt the efficacy of any test standard it is using under this program, it must promptly inform the organization that developed the test standard of this fact and provide that organization with appropriate relevant information upon which its concerns are based;

UL must not engage in or permit others to engage in any misrepresentation of the scope or conditions of its recognition. As part of this condition, UL agrees that it will allow no representation that it is either a recognized or an accredited Nationally Recognized Testing Laboratory (NRTL) without clearly indicating the specific equipment or material to which this recognition is tied, or that its recognition is limited to certain products;

UL must inform OSHA as soon as possible, in writing, of any change of ownership, facilities, or key personnel, and of any major changes in its operations as an NRTL, including details;

UL will continue to meet all the terms of its recognition and will always comply with all OSHA policies pertaining to this recognition; and

UL will continue to meet the requirements for recognition in all areas where it has been recognized.

Signed at Washington, DC, this 1st day of May, 2002.
