2022 Global Automotive Interior Material Flammability Test Standards Summary

Comparison of global automotive interior material flammability test standards in 2022.

Chinese automotive interior material flammability test standards.

China's mandatory national standards for the evaluation method of the combustion characteristics of automotive interior materials and the corresponding test standards of the United States, Europe and Japan are compared. China;

In 1987, the standard GB8410 on the burning characteristics of automotive interior materials was developed, and in 1994 and 2006, the standard was revised into the current GB8410 standard with reference to the U.S. Federal Regulation FMVSS571.302 is one of the national mandatory standards, GB/T8410 on the technical requirements of automotive interior materials, is "burning speed is not greater than 100mm/min."

European Union automotive interior materials flammability test standard:

In some enterprises in the automotive interior material performance standards cited in the standard, Europe mainly two standards are cited, respectively, IS03795 "agricultural and forestry road vehicles, tractors and machinery interior decorative material combustion performance determination" and DIN75200 "locomotive interior material combustion determination".

The scope of application of the two standards are relatively wide, ISO3795 for road passenger vehicles (such as passenger cars, trucks, trucks, coaches, etc.) and tractors and agricultural and forestry machinery, DIN75200 for cars, trucks, multi-purpose passenger cars and buses, the two standards are not qualified products need to meet the technical specifications, in 1995, the EU issued a directive 95/ In 1995, the European Union issued Directive 95/28/WC "flame retardant test for automotive interior materials, waterproof test", a certification system and evaluation standards for the combustibility of passenger car interior materials.

U.S. automotive interior material flammability test standard:

FMSS 571.302 "Combustion Characteristics of Automotive Interior Materials" stipulates that the burning time of passenger cars, multi-purpose passenger cars, trucks and buses sold in the United States is not more than 60s, and the length of burning from the timing point to the stopping point is not more than 51mm.

The American Society of Motor Engineers in 1969 developed SAE J369 "automotive interior materials flame retardant test - horizontal combustion method", this method can be seen as an industry standard, which is used in the test of automotive interior materials combustion properties of equipment, testing the environment and interior materials burning speed of the representation of detailed provisions, the standard has been revised several times, the new version for SAE ]369-2007.

Japanese automotive interior material flammability test standard:

Japan in 1973 developed] JIS D1021, the horizontal combustion method standard for automotive interior materials, the method has been revised three times, the new version of JIS

D1021, standard JISD1021 is equivalent to the adoption of ISO375, the indicators that need to be achieved for qualified products are stipulated in the regulation TRIAS48 "Test procedure for flame retardant properties of motor vehicle interior materials".

Test environment: FMVSS 571.302 does not specify the specific combustion test environment, while SAE J369-2007 stipulates that the test should be conducted in a closed fume hood, and the wind speed in the fume hood should not exceed 0.4m/s during the test, while the temperature in the combustion chamber is between 15°C and 35°C, and the relative humidity is between 45% and 75%.

ISO3795 and GB8410 stipulate that the combustion chamber should be placed in the fume hood, the test, the vertical velocity of air flow through the fume hood should be in 0.10m/s-0.30m/s, while in the combustion chamber, the temperature of the sample holder does not exceed 30 ° C.

Recommended combustion test instruments for automotive interior materials:

UL94 Horizontal Vertical Flame Tester

45 Degree Flammability Tester

Horizontal Vertical Combustion Tester

Vertical Flammability Chamber

Horizontal Flammability Tester
