Critical Radiant Flux is the main parameters of the fire risk for flooring materials, it reflects the burning and spreading ability of flooring material specimen under external heat radiation conditions. It is an important index of combustion classification for building products.
According to ISO9239-1,2 and GB/T 11785-2005 requirements, ISO 9239-1 Flooring Materials Radiant Analyzer with Good Price is measuring the critical radiant of combustion floor coverings, through the radiation environment of test chamber. It is can also be used to measure the critical radiation of the cellulose insulation floor material. Specimen is located at down horizon of 30 degree sloped gas radiation panel per horizon surface.
