A product is said to be “listed” or “approved” when it has been tested and certified by an accredited certification organization and appears in a list of certified products in either an electronic or hard copy directory published by that organization.

Testing and certification involves an initial independent, third-party evaluation of a product to determine if the product conforms to applicable standards. The process also includes follow-up inspections to help ensure sustained compliance with the standards. Certified product must be identified by certification marks issued by the testing organization.
