**SUPPLEMENTARY INFORMATION:**
**I. Notice of Final Decision**
OSHA hereby gives notice of the expansion of the scope of recognition for NSF International (NSF), as a NRTL. NSF's expansion covers the addition of four test standards to the NRTL scope of recognition.
OSHA's recognition of a NRTL signifies that the organization meets the 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 the scope of recognition. Each NRTL's scope of recognition includes: (1) the type of products the NRTL may test, with each type specified by the applicable test standard; and (2) the recognized site(s) that has/have the technical capability to perform the product-testing and product-certification activities for test standards within the NRTL's scope. Recognition is not a delegation or grant of government authority; however, recognition enables employers to use products approved by the NRTL to meet OSHA standards that require product testing and certification.
The agency processes applications by a NRTL for initial recognition and 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 a preliminary finding. In the second notice, the agency provides a 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, including NSF, which details the NRTL's scope of recognition. These pages are available from the OSHA website at *http://www.osha.gov/dts/otpca/nrtl/index.html.*
NSF submitted an application to OSHA for expansion of the NRTL scope of recognition on April 11, 2023 (OSHA-2006-0048-0019), requesting the addition of four standards to the NRTL scope of recognition. OSHA staff performed a detailed analysis of the application packet and reviewed other pertinent information. OSHA did not perform an on-site review in response to this application. OSHA staff preliminarily determined that OSHA should grant the application for test standard expansion.
OSHA published a *Federal Register* notice announcing NSF's application, preliminarily determining that OSHA should grant the application and soliciting public comment on July 24, 2025 (90 FR 34900). The agency requested comments by August 8, 2025, however no comments were received in response to this notice. OSHA is now proceeding with this expansion of NSF's NRTL scope of recognition.
To obtain or review copies of all public documents pertaining to the NSF expansion application, go to *www.regulations/gov* or contact the Docket Office at (202) 693-2350 (TTY (877) 889-5627. Docket No. OSHA-2006-0048 contains all materials in the record containing NSF's recognition.
**II. Final Decision and Order**
OSHA staff examined NSF's expansion application and examined other pertinent information. Based on review of this evidence, OSHA finds that NSF meets the requirements of 29 CFR 1910.7 for expansion of recognition, subject to the specified limitations and conditions. OSHA, therefore, is proceeding with this final notice to grant expansion of NSF's scope of recognition. OSHA limits the expansion of NSF's recognition to testing and certification of products for demonstration of compliance to the test standards listed below in Table 1.
| Test standard | Test standard title |
| --- | --- |
| UL 60335-1 | Safety of Household and Similar Electrical Appliances, Part 1: General Requirements. |
| UL 60335-2-24 | Safety Requirements for Household and Similar Electrical Appliances, Part 2: Refrigerating Appliances, Ice-Cream Appliances, and Ice-Makers. |
| UL 60335-2-89 | Household and Similar Electrical Appliances-Safety-Part 2-89: Particular Requirements for Commercial Refrigerating Appliances with an Incorporated or Remote Refrigerant Unit or Compressor. |
| UL 61010-2-030 | Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use—Part 2-030: Particular Requirements for Testing and Measuring Circuits. |
**A. Conditions**
In addition to those conditions already required by 29 CFR 1910.7, NSF also must abide by the following conditions of the recognition:
1. NSF must inform OSHA as soon as possible, in writing, of any change of ownership, facilities, or key personnel, and of any major change in its operations as a NRTL, and provide details of the change(s);
2. NSF must meet all the terms of its recognition and comply with all OSHA policies pertaining to this recognition; and
3. NSF must continue to meet the requirements for recognition, including all previously published conditions on NSF's scope of recognition, in all areas for which it has recognition.
Pursuant to the authority in 29 CFR 1910.7, OSHA hereby expands the scope of recognition of NSF as a NRTL, subject to the limitations and conditions specified above.
