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.

## Description

A certification listing is a document used to guide installations of certified products. After a field installation is completed, it is compared to the list to make sure that it complies with a regulation (e.g., a building code). 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.

## Organizations

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. Underwriter Laboratories certifications are commonly seen on products for sale in the United States.

## Example of fire door test

The following pictures illustrate an example of a successful fire test that led to a UL listing or a three-hour fire protection rating. The entire assembly is exposed to a fire for the specified amount of time per the objective of the test. Following this heat exposure, a hose stream is applied to the door. Fire doors and fire dampers are derated from the fire barriers they are in. In this case, a 3-hour rated door is acceptable for use in up to a 4-hour wall. Because it goes into a 4-hour wall, it received a 45PSI (31N/cm²) hose stream test.[1]
