JCK-2 building material flammability testing machine Introduction
The JCK-2 type building material flammability test furnace is a test method for determining whether a building material has flammability under specified conditions, and is developed according to the technical parameters specified in the national standard GB8626. The test furnace is to directly impact a vertically placed sample with a small flame in a normal combustion environment to determine the flammability of the building product. The flammability test furnace for building materials uses the German Kleinbrenner principle to determine the combustion properties of Class B building materials under direct direct impact from a small vertical flame.
