GB8410-2006 Combustion characteristics of automotive interior materials

【Scope of application】:Instrument use: used for the evaluation of the horizontal combustion characteristics of automotive interior materials. [Meet the standard]: GB8410-2006 Combustion characteristics of automotive interior materials 【Technical Parameters】: 1. Seven-inch full-color touch/display 2. Size: 7 inches Effective display size Length 15.5cm Width 8.6cm; 3. Resolution: 800*480 4. Communication interface RS232, 3.3V CMOS or TTL, serial port mode 5. Storage capacity: 1G 6. Pure hardware FPGA driver display, “zero” startup time, can be run when powered on 7. Adopt M3+FPGA architecture, M3 is responsible for instruction parsing, and FPGA focuses on TFT display 8. The main controller adopts low-energy processor and automatically enters the energy-saving mode 9. The experimental data can be stored on the touch screen, and the historical data can be accessed and queried 10. After recording the burning time, the equipment automatically calculates the test result burning speed (also known as burning rate) 11. Large fume hood, which truly meets the requirements of GB8410-2006; The combustion chamber in direct contact with the test flame is made of stainless steel as a whole, which is highly durable 12. Timing accuracy 0.1s. 13. Apply a flame to the specimen with a Bunsen lamp (i.e., a burner) for 15s. 14. The inner diameter of the Bunsen lamp is 9.5mm+0.1mm, and the length is about 100mm. 15. Test inclination: Bunsen lamp burns 90° vertically against the horizontally placed sample 16. Flame height: 20mm± 2mm to 100mm±2mm adjustable (generally adjusted to 38mm) 17. Flame time: 0-999.9s±0.1s adjustable (generally selected as 15s) 18. Continuous ignition time: 0-999.9s±0.1s, manually start and manually pause after observing the flame reaching the first marking 19. Combustion gas: liquefied petroleum gas or coal gas 20. Wind speed control/test device (optional) 21. Overall dimensions: L*W*H 1310*650*1560mm (including feet) Internal combustion tank L383W205H355H 22. Ventilation volume: >0.75 cubic meters, length * style * height about 1050mm× 640mm× 1300mm, background black, background illumination ≤ 20Lux [Instrument features]: 1. Test environment requirements: ambient temperature: -5°C-30 °C, relative humidity: ≤ 85%. 2. Power supply requirements: power supply voltage: 220V+ 10%, 50HZ, power: 100W. 3. Gas source requirements: gas source: liquefied petroleum gas. Note: The air source and link header users are self-provided 4. Test principle: The specimen is clamped horizontally on the U-shaped bracket, and the free end of the specimen is ignited with a flame at a specified height in the combustion box for 15s to determine whether the flame on the specimen is extinguished or when it is extinguished, as well as the distance at which the specimen burns and the time taken to burn the distance. Box structure: It includes three parts: combustion box, fume hood and integrated control, the combustion box is built in the fume hood, and the fume hood and integrated control are integrated design. 5. Internal structure: The combustion box is placed in the fume hood, and the internal volume of the fume hood is 20 times to 110 times the volume of the combustion box, and the length, width and height of the fume hood do not exceed 2.5 times the size of any of the other two sizes.
