Compliance with standards: Complies with GB8410, American standard FMVSS571.302, and DIN7520 "Combustion Characteristics of Automotive Interior Materials".
Test method: Place the sample horizontally on a U-shaped bracket. In a combustion chamber, ignite the free end of the sample with a flame of specified height for 15 seconds. Then, determine whether the flame on the sample has gone out, as well as the distance the sample has burned and the time it takes to burn that distance.
Scope of application: Mainly applicable to single materials or laminated composite materials used in automotive interior material parts, such as seat cushions, seat backs, seat covers, seat belts, headrests, armrests, folding roofs, all decorative backing plates, instrument panels, storage boxes, indoor cargo shelves, or rear window panels, curtains, floor coverings... ..
