In most aircraft, a large amount of thermal and acoustic insulation is used in the cockpit, passenger cabin and other areas near the cabin, which can prevent excessive noise and temperature. However, although aircraft insulation and soundproofing materials are both flame retardant and non-combustible, it does not mean that such materials will not burn under any conditions. When certain temperatures are met and sufficient oxygen is available, combustion can also occur. Therefore, it is very important to control the flame spread characteristics of aircraft thermal and acoustic insulation materials when exposed to radiant heat sources and open flames.
The flame spread tester for thermal and acoustic insulation materials is used to test the critical heat radiation flux of thermal and acoustic insulation materials after exposure to a standard heat radiation source and ignition of the specimen by an open flame. Comply with the international standard of FAR Part 25 Appendix F Part Vl, Airbus AITM 2.0053, Boeing BSS 7365 and the test method of civil aviation MH/T6042-2006.
The radiation plate test box is closed equipment that insulates materials on the sidewalls, bottom and top. PID temperature control mode, temperature control accuracy is 0.1 degrees. Equipped with a pneumatic sliding drawer, users can realize automatic control of sample entry and exit. The test time is automatically recorded and stopped. The precision of time control is 0.1s (seconds).
