FAR 25.853 Flammability Requirements for Aircraft Seat Cushions

FAR 25.253 is a Federal Aviation Administration (FAA) standard for determining the flammability of aircraft seat cushions that serves as a source of guidance when complying with Federal Aviation Regulations (FAR). The aim is to determine the maximum burn rate for materials used in these applications to reduce the incidence and severity of burn injuries while increasing evacuation time.

The test scope involves exposing three test specimens to a vertical bunsen burner flame for a period of 60 seconds or 12 seconds. The test ends after any given time and the test specimens are evaluated for flame duration, ignition time, burning length and dripping flame duration.


When we consider standard plastic semi-finished products, high-performance materials such as PEEK, PEI, PPS often meet flame resistance requirements without modification, on the other hand, standard materials such as POM or PA often do not, unless modified with special additives.
