Heat Radiation Flame Propagation Test Equipment

1. Scope of application:

    It is suitable for evaluating the performance of rail train materials such as single or composite rigid materials, materials with adhesive coating, and flexible materials with a thickness greater than 5 mm.

2. Compliant standards:

    Comply with NF P92-501 "Safety against fire: Building materials - Reaction to fire tests. used for rigid material or flexible materials thicker than 5mm", TB/T 2639.1 "Radiation test method for fire resistance test of materials for railway vehicles". ASTM E162, ASTM D3675

3. Technical parameters.

1. The test data are: flame index: i flame uniform height index: S longest flame index: h burning fever index: C.

2. Radiation test casing: height 1010mm, length 760mm, width 463mm. Stainless steel test box, the inner wall is made of flame-resistant material, equipped with transparent observation window; stainless steel tubular air inlet device, equipped with filter device to shield indoor pollution sources.

3. Radiator: The power is 500W, and the radiation surface of the radiator is a 100mm quartz disk.

4. Sample support frame: 45 degree test frame, equipped with stainless steel indicator ruler, calculate the flame spread interval.

5. Protective net: made of steel wire with a diameter of 3mm.

6. Ignition device: There are two movable ignition devices, one is the lower part of the sample and the other is the upper part of the sample. They are equipped with control valves for the flow of gas.

7. The temperature is monitored by thermocouples at the top and the air inlet, and the numerical status of the temperature difference is displayed in real time.

8. Controlled by microcomputer and software, the built-in test results such as flame index and combustion fever index can be automatically counted, and can be output and printed.
