SUPPLEMENTARY INFORMATION:

Notice of Application

The Occupational Safety and Health Administration (OSHA) hereby gives notice that Underwriters Laboratories Inc. (UL) has applied for renewal and for expansion of its recognition as a Nationally Recognized Testing Laboratory (NRTL). UL's expansion requests cover the use of two additional sites and additional test standards. OSHA's current scope of recognition for UL may be found in the following informational web page: http://www.osha-slc.gov/dts/otpca/nrtl/ul.html.

OSHA recognition of an NRTL signifies that the organization has met the legal requirements in § 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-slc.gov/dts/otpca/nrtl/index.html.

The most recent 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 was announced on November 21, 1997 (62 FR 62359), and granted on June 24, 1999 (64 FR 33913). The renewal would incorporate all of these recognitions granted to UL.

The current address of the UL facilities (sites) already recognized by OSHA are:

Underwriters Laboratories Inc., 333 Pfingsten Road, Northbrook, Illinois 60062

Underwriters Laboratories Inc., 1285 Walt Whitman Road, Melville, Long Island, New York 11747

General Background on the Applicant and Applications

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 has submitted a request, dated September 17, 1999 (see Exhibit 23), to renew its recognition, within the time allotted, and retains its recognition pending OSHA's final decision in this renewal process. UL's existing scope of recognition consists of the facilities listed above, and the test standards and supplemental programs, listed below under Renewal of Recognition.

UL also has 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 above. Moreover, UL has 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 has determined that it can grant recognition for 64 test standards listed below under Expansion 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.

Renewal of Recognition

UL seeks renewal of its recognition for the ten sites that OSHA has previously recognized. The renewal of each of these sites is and would continue to be limited to performing testing only to the test standards for which the site has the proper capability and control programs and for which OSHA has recognized UL. This treatment is consistent with the recognition that OSHA has granted to other NRTLs that operate multiple sites.

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 the on-site review report (see Exhibit 24), the program staff recommended a "positive finding," which means a positive recommendation to the Assistant Secretary regarding the renewal of recognition.

UL also seeks renewal of its recognition for 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 part 1910 by § 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 this 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 also 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.

Programs and Procedures

The renewal would include 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-slc.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.

Expansion of Recognition

Additional Sites

UL seeks recognition of the additional sites located in Tokyo, Japan, and in Ontario, Canada, as listed earlier in this notice. In processing UL's requests, 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 24-1 and 24-2), the program staff recommended a "positive finding," which means a positive recommendation on the expansion to the Assistant Secretary.

The application information that UL has submitted for these additional sites and the reports demonstrate the testing and certification capabilities at these sites. The sites are wholly owned or controlled by UL. Similar to the recognition of UL's other sites, OSHA's recognition of the additional sites would be limited to performing product testing only to the test standards for which the site has the proper capability and programs, and for which OSHA has recognized UL. As previously mentioned, this treatment is consistent with the recognition that OSHA has granted to other NRTLs that operate multiple sites. In addition, OSHA would permit the sites to use all eight of the "supplemental" programs, listed earlier in this notice, and use of which OSHA already includes under UL's scope of recognition.

Additional Test Standards

UL also seeks recognition for 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).

(1) Limited to electrical portions only.

(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 the final notice for UL's renewal/expansion, 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.

(4) The Canadian Standards Association (CSA), another NRTL, had requested recognition for this standard in an expansion application, which OSHA granted on July 3, 2001 (66 FR 35271). However, the standard was mistakenly excluded from the notice but has been added to CSA's scope of recognition.

Preliminary Finding

UL has submitted acceptable requests for renewal and expansion of its recognition as an NRTL. As noted above, in processing these requests, OSHA has performed on-site reviews of certain UL facilities. UL has addressed the discrepancies noted by the assessor following the reviews, and the assessor has included the resolution in the on-site review reports (see Exhibits 24, 24-1, 24-2).

Following a review of the application files, the on-site review reports, and other pertinent information, the NRTL Program staff has concluded that OSHA can grant to UL: (1) the renewal for the 10 sites and the test standards and programs listed above, and (2) the expansion for the additional 2 sites and test standards, also listed above. The staff therefore recommended to the Assistant Secretary that the applications be preliminarily approved.

Based upon the recommendation of the staff, the Assistant Secretary has made a preliminary finding that Underwriters Laboratories Inc. can meet the requirements as prescribed by 29 CFR 1910.7 for the renewal and expansion of its recognition. This preliminary finding does not constitute an interim or temporary approval of the applications for UL.

OSHA welcomes public comments, in sufficient detail, as to whether
UL has met the requirements of 29 CFR 1910.7 for the renewal and expansion of its recognition as a Nationally Recognized Testing Laboratory. Your comment should consist of pertinent written documents and exhibits. To consider it, OSHA must receive the comment at the address provided above (see ADDRESSES, no later than the last date for comments (see DATES above). Should you need more time to comment, OSHA must receive your written request for extension at the address provided above (also see ADDRESSES) no later than the last date for comments (also see DATES above). You must include your reason(s) for any request for extension. OSHA will limit an extension to 30 days, unless the requester justifies a longer period. We may deny a request for extension if it is frivolous or otherwise unwarranted. You may obtain or review copies of UL's requests, the on-site review reports, and all submitted comments, as received, by contacting the Docket Office, Room N2625, Occupational Safety and Health Administration, U.S. Department of Labor, at the above address. You should refer to Docket No. NRTL4-93, the permanent record of public information on UL's recognition.

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

Notice of Voluntary Termination

With respect to Docket No. NRTL2-93, Entela, Inc., has requested that OSHA withdraw its recognition of the Entela site in Taipei, Taiwan (see Exhibit 22 in Docket NRTL2-93). This withdrawal is effective immediately, and OSHA will take no further action on it. OSHA recognized this site on May 22, 1997 (62 FR 28066). Under section II.D of Appendix A to 29 CFR 1910.7, OSHA must "inform the public of any voluntary termination by Federal Register notice." This action is unrelated to our preliminary finding on the UL renewal and expansion requests. We include it herein only for convenience in processing.

Signed at Washington, DC, March 7, 2002.

John L. Henshaw,
Assistant Secretary.
