The TH-5605 Automotive Interior Decoration Flame Resistance Testing Machine complies with GB8410, the American standard FMVSS571.302, and DIN7520 "Combustion Characteristics of Automotive Interior Materials". The sample is horizontally clamped on the U-shaped bracket. In the combustion chamber, the free end of the sample is ignited with a flame of the specified height for 15 seconds. Then, determine whether the flame on the sample goes out, as well as the distance the sample burns and the time it takes to burn that distance. Interior materials include single materials or laminated composite materials used for automotive interior parts, such as seat cushions, seat backs, seat covers, seat belts, headrests, armrests, movable folding roofs, all decorative panels, instrument panels, storage boxes, interior cargo shelves, or rear window sills, curtains, and floor coverings.
