Product Details

TPP Thermal Protection Performance Tester SPI Test Equipment

 

1, Product introduction:


TPP Thermal Protective Performance Tester is used to evaluate the potential skin burn grade of flame retardant protective clothing, protective gloves, etc. and the ability of materials to prevent heat convection and heat radiation penetration.


2, Standards:


Comply with GB 38302-2019, ASTM F2700-08 and other standards for protective clothing.


3, Technical specifications:


1. The test instrument includes the sample seat assembly, the bracket of the sample seat assembly, the heat source, the sensor assembly, the recorder, etc., as well as the gas flowmeter, the burner and the radiometer.
2. Two size sample boxes, 150mm × 150mm for protective clothing test, 160mm × 160mm for testing protective gloves.
3. Equipped with pneumatic sample holder and water-cooled plate protection (pneumatic type), the copper calorimeter has a built-in cooling sensor, which is used to drive compressed air to help test preparation more quickly.
4. The Venturi tube has a diameter of 38mm and an inner hole diameter of 5/16 inch. It can provide 800-1200 BUT heat output. The burner port is a metal mesh structure. The lower air valve of the burner can be adjusted to adjust the mixing ratio of air and combustible gas
5. 9 T150 quartz infrared tube arrays, which can provide heat radiation flux no less than 41.5kW/m2 ± 4 kW/m2
6. Under the thermal radiation of quartz infrared tube, the total heat flux can be set to less than 83kW/m2 ± 2kW/m2 by adjusting the fuel gas supplied to Meker burner
7. The hole diameter of copper plate calorimeter thermocouple is 1.2 mm, the depth is 0.13 mm, and the thermocouple wire is connected. ISO and Chinese standards are three uniformly distributed thermocouples, and American standards are one central thermocouple
8. The data acquisition system of the sensor can record the temperature not lower than 1000 ℃. The resolution of the temperature acquisition system is 0.1C
9. The automatic data acquisition system has a data acquisition speed of 10Hz and provides cold junction compensation for the measured data of thermocouples.
10. The sensor surface is coated with a layer of black paint, and its radiation rate should be greater than or equal to 0.9
11. Radiometer (or heat flow meter) for calibrating the test instrument, water-cooled type, with a working range of 0-100KW/m2, and a large application range of Zui of 150%
12. The radiator is equipped with a water cooling self circulation system, without the need to provide an external water source
13. The response time of the radiometer is less than 200ms, the emissivity is greater than 0.95, and the output signal within the working range is greater than 5mv
14. The rotameter is equipped to adjust the combustion gas flow with an accuracy of ± 2% and a range of more than 3L/min
15. Equipped with pointer pressure gauge, the inlet pressure can be adjusted through the pressure reducing valve, and the range of the pressure reducing valve is 0-15psi
16. Equipped with quarter rotary plug, which can manually cut off combustible gas
17. Equipped with computer and printer, standard test software, temperature rise curve, secondary burn Stoll and other standard curves
18. The whole machine adopts the separated design of gas and electrical control (left electrical control, right gas control, middle combustion test, scientific design and high safety.
