The touch screen control building materials flammability test furnace adopts stainless steel box, which is an upgraded product with new touch screen control, specimen controllable automatic lifting, and Bunsen lamp advance and retreat adjustment functions on the basis of the old JCK-2 product, and is a high-configuration building materials combustion grade test instrument produced in strict accordance with the national standard GB8626-2007. (The red part is the parameter required by the third-party testing unit to accept the mandatory requirements) The building materials flammability test furnace is to determine the flammability of building products by directly impacting vertically placed specimens with a small flame in a normal combustion environment. The building materials flammability test furnace uses the German Kleinbrenner principle to determine the combustion performance of Class B building materials under the direct impact of a small flame in the vertical direction (i.e., used for the determination of building material combustion performance/flame retardant grade B). 【Relevant Standards】

ISO11925-2:2002 E “Flammability Test Method for Building Materials” Design Standard: GB/T8626-2007 “Flammability Test Method for Building Materials” In addition, GB8626-2007 4.10 requires the wind speed device to be optional
