Compliant with standards: Compliant with GB8410, American standard FMVSS571.302, and DIN7520 "Combustion Characteristics of Automotive Interior Materials".
Test method: Clamp the sample horizontally on a U-shaped bracket, ignite the free end of the sample with a specified height flame in the combustion chamber for 15 seconds, and determine whether the flame on the sample has extinguished, as well as the distance and time required for burning the sample at that distance.
Scope of application: Mainly applicable to single materials or laminated composite materials used in automotive interior materials and parts, such as seat cushions, seat backs, seat covers, seat belts, headrests, armrests, folding tops, all decorative lining panels, instrument panels, glove boxes, indoor cargo racks, or rear window sills, curtains, floor coverings
