Step-by-step explanation:
A Nationally Recognized Testing Laboratory (NRTL) is an independent organization recognized by the Occupational Safety and Health Administration (OSHA) to test and certify products for safety. The primary purpose of an NRTL is to ensure that products meet the necessary safety standards and regulations before they are placed on the market. This includes conducting rigorous testing and evaluating the performance of products according to established criteria.
For example, UL (Underwriters Laboratories) is one of the most well-known NRTLs. They test a wide range of products, including electrical equipment, to ensure they are safe for use. By certifying products, NRTLs provide assurance to consumers, businesses, and regulatory agencies that the products have been tested and meet the required safety standards.
