Brief introduction: Thermal protection performance tester is used to detect protective clothing, safety shoes, gloves, helmet outside surface thermal protection performance, such as through the established under the action of thermal radiation heat source, thermal protection performance of test materials. Accord with NFPA 1971, ASTM D4018, GB 8965.1 2009, the ISO 12749 test standard, etc Technical parameters: 1. The test instruments should include sample components, sample components of stents, heat source, shield and sensor components, recorder and washer, also should have gas source, gas meter, burner and sensors. ; 2. Portable stainless steel protection plate, but keep out the flame, reduce the test error; 3. The two 45 degrees Meker burner, with 9 quartz tube provides a standard convection heat source; 4. Meker burner caliber is 38 mm, inner hole diameter of 5/16 of an inch, 800-1200, BUT the heat output, burner for metal mesh structure, adjustable burner under the nerazzurri valve, adjustable air and fuel gas mixture ratio; 5. 9 T150 quartz infrared tube array, provides thermal radiation flux for 13-40 kW/m2 + 4 kW/m2; 6. Under the quartz tube infrared thermal radiation, by adjusting the supply Meker gas burner, the total heat flux can be set to 83 kW/m2 + 2 kW/m2; 7. The calibration of heat flow meter for water-cooled type, working range of 0-100 kw/m2, maximum range is 150%; 8. Heat flow meter response time is less than 200 ms, radiation rate is greater than 0.95, the work within the scope of the output signal is greater than 5 mv; 9. The amount of copper plate heat meter device, can be used to detect the convective heat and radiation, at the same time can detect sample temperature on the back; 10. Equipped with thermal radiation flux display instrument, can even show heat flux values;
