Welcome to the Nationally Recognized Testing Laboratory (NRTL) Program, which is a part of OSHA's Directorate of Technical Support and Emergency Management. The Program recognizes private sector organizations as NRTLs, and recognition signifies that an organization has met the necessary qualifications specified in the regulations for the Program. The NRTL determines that specific equipment and materials ("products") meet consensus-based standards of safety to provide the assurance, required by OSHA, that these products are safe for use in the U.S. workplace.

For purposes of meeting the NRTL product-approval requirements in OSHA standards, e.g., those under Subpart S of 29 CFR Part 1910, OSHA only accepts equipment or products approved by one of the NRTLs listed below. See the OSHA web pages for information on each NRTL's scope of recognition, or contact OSHA or the NRTL for additional information.
