The critical radiation flux is the main parameter to investigate the fire hazard of the flooring material. It characterizes the combustion spread capacity of the flooring material burned under the condition of external heat radiation. It is an important indicator in the grading system of flooring materials used as building products.rPrTextile Testing Instruments, Testing Equipment Manufacturer

Floor material thermal radiation board test meets the requirements of ISO9239-1,2 and GB / T 11785-2005. In the test chamber, the floor covering material is burned in a certain thermal radiation environment to measure the critical thermal radiation value. It can also be used to measure the critical radiation value of attic floor cellulose insulation material.rPrTextile Testing Instruments, Testing Equipment Manufacturer
