Doors and frames are given a fire-resistance rating after extensive testing by the Underwriters Laboratory in the United States, or another testing agency in other countries. Once tested, the door and frame receive a label that describes the amount of time the component is expected to provide protection when exposed to fire. When combined, all of the components of the door form an assembly that protects the opening. For this reason, all components of the door must include a rating label, including the door panel, the door frame, locksets, gaskets, hinges, and door protection plates.
