DX8401 Radiant Heat Flux Testing Equipment for Floor Covering Materials
Conform to the standard: meet the requirements of GB/T11785-2005 and ISO9239-1 "Determination of Combustion Performance of Paving Materials - Radiant Heat Source Method".
Scope of application:
It is suitable for testing flooring materials that are placed horizontally with small flame ignition under specified conditions and exposed to an inclined thermal radiation field. Suitable for all kinds of flooring materials. Such as: textiles, carpets, cork, wood, rubber sheets and plastic flooring and floor spraying materials. The device can react to the combustion properties of the paving material, including the substrate used, and changes in the backing material, the sublayer material or other aspects of the paving material may affect the test results, and it is used to test and describe the combustion characteristics of the paving material in pairwise thermal reaction to ignition under laboratory control conditions.
Main technical indicators:
The radiation box is tilted 30 degrees and can be adjusted
The inlet heat flux is measured by the inlet heat flux
The gas flow rate in the flue is (2.5±0.2) m/s
The water temperature was 15°C-25°C
The radiant flux of the 9 points of the radiant panel should meet the corresponding specifications (see standard requirements)
The exhaust fan is infinitely adjustable
