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.
