Analysis of FAR25.853 Test Standards for Common Combustion Properties of Aircraft Materials

Aircraft Material Combustion Performance Test Far25.853 - Standard Name Far25.853: Fire Protection of Aircraft Interior Materials - Flame Retardant Fire Test Aircraft Material Combustion Performance Far25.853 - Horizontal Fire Test Far 25.853 Horizontal Fire Test The flame propagation rate of the member, the test apparatus is similar to UL 94 HB. 

The test was performed in an unventilated chamber according to US Federal Test Method Standard 191, 5906. Take the average value of 3 measurements as the result. This level test corresponds to ISO 3795, DIN 75200 and FMVS302. 

Far 25.853 Horizontal Fire Test - Test Method The test pieces used in this test are 3, and the thickness is the thickness used. Marked at 292mm and 38mm from where the flame was applied. The specimen position is horizontal. Ignite the source Bunsen burner. The time to apply the flame is 15s. Test its maximum flame spread rate.
