Flammability of automotive interior materials English
1 Scope
This standard specifies the technical requirements and test methods for the horizontal flammability of automotive interior materials.
This standard is applicable to the assessment of automotive interior materials.
As automotive interior parts (positions, layout and application conditions of the parts, ignition sources, etc.) differ considerably from the test conditions specified in this standard, this standard is not applicable to the assessment of all the actual flammability of automotive interior materials.
2 Terms and Definitions
2.1
Burning rate
The ratio of the burnt distance measured under this standard to the time used in burning this distance, in mm/min.
2.2
Composite material
Material comprising layers of similar or different materials fused, adhered or welded tightly together.
2.3
Exclusive material
Homogeneous material
Different materials connected discontinuously together (such as by sewing, high-frequency welding or riveting) shall not be regarded as composite material, and each of the materials is exclusive material.
2.4
Exposed side
The side of the part installed in the automobile and facing the people inside the automobile.
2.5
Interior materials
Any exclusive material or composite material used for automotive interior parts, such as cushions, backrests, seat covers, safety belts, headrests, movable folding ceiling, all decorative lining boards (including indoor fender, side fender, back fender and ceiling lining), gauge panel, sundries box, indoor shelf or back window board, curtain, floor cover, sun visor, wheel cowl, motor cover, and any other indoor organic material, including buffer devices for cushioning impact in case of collision.
3 Technical Requirements
The flammability of interior materials must meet the following technical requirements:
Firing rate is no greater than 100 mm/min.
4 Test Method
4.1 Principle
Fit the sample horizontally on a U-shaped support then ignite the free end of the sample on a flame of the specified height in the combustion box. 15 seconds later, determine whether the flame on the sample goes out or at what time it goes out, the burnt distance of the sample, and the time used in burning this distance.
