Overall thermal protection performance tester experimental parameters

 The overall thermal protection performance tester detects the thermal protection performance of materials under the action of a given thermal radiation heat source. It is used to detect the thermal protection performance of protective clothing, safety shoes, gloves, and helmets' outer surfaces.

 

As a modern technology enterprise integrating R&D, manufacturing, sales, training, and services, Standard Sales Group (Hong Kong) Co., Ltd. is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, material environmental climate aging, etc., and non-standard customization is also acceptable. Targeted tests can be carried out according to customer requirements before purchase to ensure that the purchased instruments are applicable.
 

Applicable standards:

ISO 17492, ASTM F2700, ASTM F2703, NFPA 1971 and NFPA 2112

 

Experimental parameters:

1. Two Meker burners placed at 45 degrees, with 9 quartz tubes to provide a standard convection heat source

2. The Maker burner has a diameter of 38mm and an inner hole diameter of 5/16 inches, providing a heat output of 800-1200BUT

3. An array of 9 T150 quartz infrared tubes can provide a heat radiation flux of 13-40kW/m2±4kW/m2

4. Under the heat radiation of the quartz infrared tubes, the total heat flux can be set to 83kW/m2±2kW/m2 by adjusting the gas supplied to the Maker burner

5. The calibrated heat flux meter is water-cooled, with an operating range of 0-100KW/m2 and a use range of 150%

6. The response time of the heat flow meter is less than 200, the emissivity is greater than 0.95, and the output signal within the working range is greater than 5mv

7. The rotor flowmeter can adjust the combustion gas flow rate with an accuracy of ±2% and a range greater than 3L/min

8. The pointer pressure gauge, the intake pressure can be adjusted by the pressure-reducing valve, and the pressure-reducing valve range is 0-15psi

9. The resolution of the temperature acquisition system is 0.1℃, and the accuracy is ±0.75℃

 

Main features:

1. Including the sample seat assembly, the bracket of the sample seat assembly, the heat source, the protective cover, the sensor assembly, the recorder, and the gasket, it should also have a gas source, a gas flow meter, a burner, and a sensor

2. The movable stainless steel protective plate can block the flame and reduce the test error

3. The burner port is a metal mesh structure, and the lower air valve of the burner is adjustable, which can adjust the mixing ratio of air and combustible gas

4. The cone disk calorimeter device can be used to detect convection heat and radiation heat, and can also detect the temperature on the back of the sample

5. Equipped with a thermal radiation flux display instrument, which can display the heat flux value in real-time

6. A quarter-turn plug can manually cut off the combustible gas

7. Equipped with a computer and printer, with standard test software, and provides standard test curves
