GB8410-Automotive interior combustion test methods and standards

The fire performance of automotive interior parts has received extensive attention. The combustion test methods and standards for automotive interior parts mainly include American Standard FMVSS302, Canadian Standard CMVSS302, National Standard GB8410, and European Standard Directive 95/28/EC. GB8410 standard name GB8410 Flammability of automotive interior materials. GB8410 standard specifies the technical requirements and test methods for the characteristics of horizontal tongs for automotive interior materials. The GB8410 standard is applicable to the evaluation of the horizontal combustion characteristics of automotive interior materials. The GB8410 standard technical requirements require that the combustion speed of interior materials is not greater than 100mm/min. Burning rate: The ratio of the measured burning distance to the time it takes to burn this distance, in millimeters per minute (mm/min). GB8410 Test principle of combustion characteristics of automotive interior materials Hold the sample horizontally on a U-shaped bracket, and ignite the free end of the sample with a flame of a specified height in a combustion box for 15 seconds to determine whether the flame on the sample is extinguished, or when it is extinguished. , and the distance the sample burns and the time it takes to burn that distance. GB8410 Test of combustion characteristics of automotive interior materials - A/B/C/D/E classification According to different combustion distances and combustion rates of automotive materials, there are five levels of material classification. FMVSS302 Standard Name FMVSS302 Federal Motor Vehicle Safety Standard No.302; Flammability of interior materials. FMVSS302 The combustion performance of interior trim materials for federal traffic vehicles. Purpose and Scope of FMVSS302 Standard This FMVSS302 standard specifies the requirements for flame retardancy of materials used in automobile passenger compartments. The purpose of this standard is to reduce the number of casualties caused by vehicle fires, especially those originating from the interior of the vehicle such as matches or cigarettes. The FMVSS302 standard applies to passenger cars, utility vehicles, trucks and buses. FMVSS302 sample size and quantity Sample size and quantity: 102mm×356mm×Thickness (the actual thickness of the sample used in the automobile, but not less than 13mm, if it is greater than 13mm, it should be cut into 13mm.) At least 10 samples, if there are different burning speeds in different directions, they should be in different All directions shall be sampled at least 10 specimens in each direction. If the size of the material does not meet the test requirements, make a sample that meets the test requirements.
