Thermal Radiation Flame Propagation Tester

TESTech Instrument (Suzhou) Technologies is one of the leading manufacturers and suppliers of thermal radiation flame propagation tester in China. Welcome to wholesale premium test equipment at competitive price from our factory. If you have any enquiry about quotation, please feel free to email us.

The TESTECH thermal radiation flame propagation tester is used to evaluate rigid and flexible materials with thickness greater than 5 mm. It is developed according to the French construction material and railway vehicle flame-retardant test standard NF P 92-501.

 

The test principle is to expose the specimen to thermal radiation of 30 kW/m2, which may cause the specimen to release combustible gases and then ignite these volatile gases. Flame spread behavior is observed, and combustion data are collected to estimate released heat.

• Stainless steel test chamber with non-combustible inner wall material and transparent observation window.
• Stainless steel tubular air inlet device equipped with filtration to isolate indoor contamination sources.
• Forty-five-degree test frame with stainless steel indicator scale for flame spread distance calculation.
• Thermal radiation device capable of providing 30 kW/m2 radiant heat flux.
• Power controller for adjusting radiant output and regulating thermal radiation flux.
• Panel display of operating power value of the radiation device, reducing frequent calibration procedures.
• Upper and lower stainless steel burners to ignite combustible volatile gases released by the specimen.
• Needle valves to control flame height of upper and lower burners, with flame height gauges provided.
• Continuous pilot flame arrangement for convenient ignition of the upper and lower burners before testing.
• Quarter-turn plug device for convenient shut-off of burner and ignition gas supply.
• Thermocouples at the top and air inlet monitor temperature and display temperature difference in real time.
• Standard test software automatically calculates flame index and combustion heat index.
• Built-in report function with data output and printing capability, supported by a user-friendly interface.
• Test data include flame index I, average flame height index S, longest flame index H, and combustion heat index C.

• Width: 1900 mm.
• Depth: 460 mm.
• Height: 2100 mm.
• Shipping weight: 208 kg including 158 kg for the main unit and 50 kg for the table.
• Rated power of radiator: 500 W.
• Accuracy of wattmeter: class 0.5.
• Pressure resistance range of gas regulating valve: less than 0.1 MPa.
• Power supply: 220V, 50Hz, 550W.
