Certification listing

A certification listing is a document used to guide installations of certified products, against which a field installation is compared to make sure that it complies with a regulation (e.g., a building code). Typically, products or items are required to be installed or used in accordance with a subject-related certification listing if those products or items are subject to product certification and must be used in a specific manner in order to be safe for use. Certification listings are issued by organisations that are usually nationally accredited for doing both testing and product certification work, in accordance with nationally accredited standards.

Often, products or items are required—by law, void of warranty, or other means—to be installed or used in accordance with a subject-related certification listing if those products or items are subject to product certification and must be used in a specific manner in order to be safe for use.
