Standard Requirements for Safety Performance Testing of Automotive Interior Materials

The safety performance evaluation indicators of car interior materials mainly include atomization, flame retardancy and the content of air pollutants in the car. There are also different standards for different indicators of these security tests.

Aerosolization test:
The atomization test of automotive interior materials allows to control the volatiles contained in these materials to effectively reduce the internal environmental pollution. and automotive interior materials manufacturers to control product quality.

Currently, the atomization test methods of car interior materials include gravimetric method, gloss method and haze method.process, the difference is whether the measured parameter is condensing composition, haze value or haze.

The standards that can be referred to are the German standard DIN75201, the American standard SAEJ1756, ASTM D5393, the British standard BS EN14288 and the standard ISO 6452.

Flame Retardancy Test:
The Flame Retardancy Test is a test method for the ability of the tested object to retard flame propagation, propagation and diffusion. After years of development, flame retardancy testing has formed a variety of standards and has become a very important test item in related industries. Most of the combustion performance tests of automotive interior materials require that in a harsh test environment, the fire source specified in the standard is used to affect the test material with different fire sources, and then the combustion phenomenon of the material is observed and evaluated.

The flame retardancy test can refer to the following standards: GB8410-2006, DIN75200, ISO3795, ASTMD5132, FMVSS302, JISD1201, UL94, etc.
Determination of the content of air pollutants in the car
According to the pollutant source, the nnon-metallic materials, components and vehicles tested for air pollutants. There are three main types of vehicle air pollutant testing: odor evaluation, which primarily relies on the human sense of smell for quality assessment (VDA270), and can also be measured with an electronic nose (SAEJ351); quantitative analysis of volatile organic pollutants (VOCs), including air chromatography, thermal desorption method, liquid chromatography, etc.; for the determination of carbon and nitrogen oxides, the non-spectral infrared gas determination method (GB/T28370) can be used.

Currently, relevant standards have been issued for VOC testing of complete vehicles in China, but there is no relevant standard for VOC testing of non-metallic parts, and domestic VOC testing methods for non-metallic parts are not uniform.
Parts and materials testing standards include: ISO12219, VDA270, DIN13130, DINEN13725, VDA275, VDA277, VDA278, SAEJ351 and many other standards.
The whole vehicle test method and limit value requirements of organic pollutants are mainly based on the national standard HJ/T400-2007 and GB/T27630-2011 for testing and evaluation.
