ISO11925-2 Building Material Ignitability Flammability Test Chamber

Scope of application

The building material flammability test furnace is used to measure the flammability of building products by directly impacting a vertically placed sample with a small flame in a normal combustion environment. The building material flammability test furnace uses the German Kleinbrenner principle to measure the combustion performance of Class B building materials (i.e., for determining the combustion performance/flame retardant grade B of building materials) under the direct impact of a small flame in a vertical direction.
