Hardware has the same fire rating durations as doors and frames.
A properly sized closing device is the last of the “basic” fire door hardware requirements. A fire door must be in a closed and latched position to serve as a protective barrier in the event of a fire. For this reason, either listed spring hinges or a listed door closer are required to ensure that the door will close properly.
Conditions of Test Acceptance:
−Assembled hardware must keep the door closed during and after the fire.
