Certification listing

A Certification listing is a document against which a field installation is compared to make sure that it complies with a regulation, such as a building code.

The article describes particular North American practices. Terms used may have different meaning and application elsewhere. Different approaches and legal requirements may apply elsewhere.

Products or items that are subject to product certification and must be used in a specific manner in order to be proven safe for use, are typically required to be installed or used in accordance with a subject-related listing, which is a document issued by an organisation that is nationally accredited for doing both testing and product certification work, in accordance with nationally accredited standards. The following is one example of millions of such listings that exist around the world for nearly countless numbers of products, such as toasters, fire extinguishers, fireproofing plasters, etc. This example is a duplicate of an Underwriters Laboratories firestop mortar listing based on the fire test depicted under the Fire-resistance rating article. This article is also augmented with real-life photographs from the test upon which this listing was based, for better understanding. The actual certification listing includes no photographs - only text and drawings.
