What is an NRTL?
A Nationally Recognized Testing Laboratory (NRTL) is an independent laboratory recognized by the Occupational Safety and Health Administration (OSHA) to test products to the specifications of applicable product safety standards – such as those from Underwriters Laboratories (UL) and other standards-writing bodies. An NRTL’s function is to provide an independent evaluation, testing, and certification of any electrically operated or gas- and oil-fired product. Intertek is recognized as an NRTL in the United States and, in a similar capacity, as a Testing Organization (TO) and Certifying Body (CB) in Canada, and as a Notified Body in Europe.
