Test Principle
The building materials flammability test furnace is in the normal combustion environment, with a small flame directly impacted the vertical specimen to determine the combustibility of the building products. The flammability test furnace for building materials is based on the principle of Kleinbrenner (Klein Brenner), which is directly impacted by a vertical flame. It is used to determine the combustion performance of B grade building materials (namely, the judgement of burning performance and flame retardant grade B of building materials).
