Analysis of FAR25.853 Commonly Used Combustion Performance Test Standards for 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 Combustion Test Far 25.853 Horizontal Combustion Test This test is used to determine materials or The flame propagation rate of the components, the test device is similar to UL 94 HB. According to the US Federal Test Method Standard 191, 5906, the test system is carried out in an unmanned ventilated chamber. Take the average of 3 measurements as the result. This level test corresponds to ISO 3795, DIN 75200 and FMVS302. Far 25.853 horizontal burning test-test method The test piece used in this test is 3, the thickness is the thickness used. Counting from the place where the flame is applied, marks are made at 292mm and 38mm. The position of the test piece is horizontal. The ignition source is the Bunsen burner. The flame time is 15s. Test its maximum flame propagation rate.
