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.

Famous quotes containing the words fire, door and/or test:
“You can much sooner dry you by such a fire as you can make in the woods than in anybody’s kitchen, the fireplace is so much larger, and wood so much more abundant.”
—Henry David Thoreau (1817–1862)
“When they sometimes
Come down the stairs at night and stand perplexed
Behind the door and headboard of the bed,
Brushing their chalky skull with chalky fingers,
With sounds like the dry rattling of a shutter,”
—Robert Frost (1874–1963)
“There is held to be no surer test of civilisation than the increase per head of the consumption of alcohol and tobacco. Yet alcohol and tobacco are recognisable poisons, so that their consumption has only to be carried far enough to destroy civilisation altogether.”
—Havelock Ellis (1859–1939)
