DIN7520 Automotive Interior Material Combustion Fire Resistance Testing Equipment

Standard:

Conforms to GB8410, American Standard FMVSS571.302, DIN7520 "Combustion Characteristics of Automotive Interior Materials".

Test method:

The sample is horizontally clamped on a U-shaped bracket. After the free end 15S of the sample is ignited in the combustion box with a prescribed height of flame, it is determined whether the flame on the sample is extinguished, and the distance the sample burns and the distance to burn The time used.

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, head restraints, armrests, movable folding roofs, all decorative Liners, dashboards, glove compartments, interior cargo racks, or rear window sills, curtains, floor coverings.....
