Invention patent: ZL 2014 1 0136677.8
The main purpose
The instrument is mainly used to test the anti-radiation heat penetration performance of protective materials.
Technical index
1. The comprehensive test device for anti-radiative heat penetration performance is composed of a radiant heat source and a sample amplitude test box.
2. The radiant heat source adopts infrared halogen tungsten lamp with AC voltage of 220V and power of 500W.
3. Radiant heat flux: 10kW/m2±1kW/m2 and 40kW/m2±1kW/m2, the radiant heat flux radiated on the surface of the sample is evenly distributed.
4. Sample radiation test box: equipped with timing and automatic control shielding baffle.
5. Measurement control box: composed of thermocouple, digital thermometer, absolute power meter and DC digital voltmeter.
6. Thermocouple performance requirements:
      Measuring range: 0℃-800℃.
      Accuracy level: level 3.
      Time constant: no more than 8s.
7. Performance requirements of DC digital voltmeter:
