Wire Bending Machine Precision 0.1mm Stainless Steel Box Car Interior Material

Precision 0.1mm Stainless Steel Box Car Interior Material Burning Test Box

Automotive interior material burning test machine JD-3053

Applicable industry:

This combustion test device is suitable for identifying the horizontal combustion characteristics of interior materials of automobiles (cars, multi-purpose passenger cars, trucks and buses).

Applicable standards:

Meet the requirements of GB8410-2006, TL1010, GM6090M, DIN7520, GM9070P, MVSS302, GMW3232, GS97038.

Test method:

The sample was horizontally held on a U-shaped bracket and ignited by a small flame for 15 s in a combustion chamber, and the flame was ignited at the free end of the sample. Record whether the flame is extinguished or when it is extinguished; and the distance the sample burns and the time it takes to burn the distance.

Data reading: burning time, afterflame time, burning distance

Test result: Burning speed V (mm/min) converted by the following formula: V=60 X(L / T), in the mode: L—burning distance mm; T—time s used for burning distance L test results

Instrument composition:

1. Combustion system: anti-corrosion combustion box, inner diameter 9.5mm gas lamp nozzle; ignition automatic control system, intake and exhaust system.

2, timing system: burning timer, afterflame timer.

3. Test fixture: It consists of two U-shaped corrosion-resistant metal plates. One of the brackets is provided with a heat-resistant metal wire diameter of 0.25 mm and a support line with a distance of 25 mm.

4. Glass observation window: The front part of the combustion box is provided with a heat-resistant glass observation window, which can easily observe the change of burning speed during combustion.

5. Stainless steel box: There are 10 venting holes with a diameter of 19mm at the bottom of the combustion box. The four walls are close to the top with a 13mm wide ventilation slot. The entire combustion chamber is supported by four legs 10 mm high. A small hole for inserting a thermometer is arranged at the top of the combustion box, and the hole is arranged at the center of the top and the back, and the center is 20 mm from the inner side of the rear panel.
