Standard Requirements of Safety Performance Testing for Automotive Interior Materials

The safety performance evaluation indicators of automobile interior materials mainly include atomization, flame retardancy, air pollutant content in the car, etc. There are also different standards corresponding to the different indicators of these security tests.
Atomization test:
By carrying out atomization tests on automobile interior decoration materials, the volatile substances contained in these materials can be controlled to reduce effectively the risk of vehicle interior decoration. Internal environmental pollution has become an important way for automobile and automobile interior material manufacturers to control product quality.
At present, the fogging testing methods for automobile interior materials include gravimetric method, gloss method and haze method. LeuThe principles of nebulization are the same and they all use the principle of volatilization and condensation of substances to achieve nebulization. process, the difference is that the measured parameter is the condensation component, haze formation value or haze.
Standards that can be referred to include German Standard DIN75201, American Standard SAEJ1756, ASTM D5393, British Standard BS EN14288 and ISO 6452.
Flame Retardant Test:
Flame retardant test is a test method for the ability of the tested object to retard the continuation, propagation, diffusion of flame, etc. After years of development, flame retardant testing has formed a variety of standards and become a very important testing item in relevant industries. Most combustion performance tests of vehicle interior materials require that the test materials be subjected to differentnte fire sources in harsh test environments using fire sources specified by the standards, and then the combustion phenomena of the materials are observed and evaluated.
The flame retardancy test can refer to the following standards: GB8410-2006, DIN75200, ISO3795, ASTMD5132, FMVSS302, JISD1201, UL94, etc.
Measuring the content of air pollutants in the vehicle:
Depending on the source of the pollutants, air pollutants are detected on materials, parts and entire vehicles. There are three main categories of tests for air pollutants in cars: odor assessment, which mainly relies on human smell for quality assessment (VDA270), and electronic nose measurement (SAEJ351) can also be used; quantitative analysis of volatile organic pollutants (VOC), including top air chromatography, thermal desorption method, chroliquid matography, etc. ; for the determination of carbon and nitrogen oxide content, the non-dispersive infrared gas determination method (GB/T28370) can be used.
At present, national standards have been published for VOC testing of complete vehicles, but there is no relevant standard for VOC testing of non-metallic parts. National VOC testing methods for non-metallic parts are not unified.
The testStandards applicable to parts and materials include: ISO12219, VDA270, DIN13130, DINEN13725, VDA275, VDA277, VDA278, SAEJ351 and many other standards.
The testing methods and limit requirements of organic pollutants for complete vehicles are mainly based on the national standard HJ/T400-2007 and GB/T27630-2011 for testing and evaluation.
