FAR 25.853 Aircraft material combustion performance test-45° combustion test

Material Flame Retardant Test, Fire Test Far25.853 - Standard Name

• Far25.853: Fire Protection for compartment interior

• Far25.853: Fire Protection of Aircraft Interior Materials - Flame Retardant and Fire Test

Certain components used in cargo holds and luggage compartments must be tested using both the 45° burning test and the vertical burning test. The ignition source for the 45° test is the same as the horizontal combustion test. The test was conducted in a non-ventilated chamber, and the average of three measurements was used as the result.
