FMVSS302 Car interior decoration flammability test chamber

FMVSS 571.302 Automobile interior material combustion tester

Introduction:

1. The combustion test of automotive interior materials is mainly based on the national standard GB8410-2006 and the American standard FMVSS 571.302 and other standards to simulate the combustion performance safety test items.

2.The combustion test of automotive interior materials uses a Bunsen burner of a specified size and a specific fuel gas source (liquefied petroleum gas or gas), and flames the automotive interior materials in a horizontal state according to a certain flame height and a certain flame angle Time, to evaluate the ignitability and fire hazard of the test specimen by ignition, duration and length of combustion.

3. The combustion tester for automotive interior materials is mainly used for qualitative evaluation of the flammability of automotive interior materials. It is applicable to various types of automotive interior material manufacturers and their research and production and quality inspection departments of material parts, and it is also suitable for insulation materials, engineering plastics or other solid combustible materials industries.
