How Fire Rating is Established

All fire testing is done by independent agencies recognized internationally that are responsible for testing the full door, frame, and hardware assemblies to ensure that each element meets or exceeds their regulation standards. There are two standard phases for testing fire ratings.

Phase One: Full door assemblies, including the door slab, frame, and hardware, are placed into a specialized furnace where they are exposed to increasing heat, flame, and pressure. This simulates a real fire and lasts for a specified length of time to pass each fire rating.

Phase Two: Once the time for the rating has been reached the assembly is rapidly cooled with either cold water or a fire suppressant.

Only assemblies that remain secure at the end of this testing pass inspection and gain the fire rating.
