GB8410 Test Method for Combustion Characteristics of Automotive Interior Materials
Automotive interior materials refer to single or layered composite organic materials used for parts in the cab and passenger compartment, including: seat cushions, seat backs, seat covers, seat belts, headrests, armrests, and movable folding roofs , All decorative liners (including door inner panels, front panel, side panels, rear panel, headliner, etc.), instrument panel, glove box, interior shelf panels (including rear window sills) , Curtains, floor coverings, sun visors, wheel cover coverings, bonnet coverings, and organic materials for absorbing impact energy in a crash, cushioning devices, etc. The car interior horizontal combustion tester is a test instrument for measuring the combustion characteristics of automobile interior materials. The test experiment is carried out according to the GB 8410 test method. GB8410 test method: Hold the sample horizontally on the U-row bracket, and after igniting the free end of the sample with a flame of a specified height in the combustion box for 15s, determine whether the flame on the sample is extinguished, or when it is extinguished, and the distance and distance of the sample burning. The time it takes to burn this distance. Burning speed (V) calculation: V=60×(L/T) V Combustion speed, in millimeters per minute (mm/min); L Combustion distance, in millimeters (mm); T Time for combustion distance L, in seconds (s). GB8410 test technical requirements: The burning speed is not more than 100mm/min. Main parameters: 1. Flame time: 0-999.9s±0.1s adjustable; 2. Delay time: 0-99h59m59.99s±0.1s, manual start/pause; 3. Installation of combustion box: the bottom of the combustion box is 10mm away from the bottom plate of the equipment; 4. Test wind speed: The vertical air velocity of each 100mm before and after the combustion box is between 0.10m/s ~ 0.30m/s, and the On the right side of the device, an anemometer monitoring outlet is added.
