Floor Material Burning Performance Tester
Theis used to tester a variety of flooring materials, such as: textile carpets, cork, wood, rubber and plastic flooring and floor spray materials. The results can reflect the combustion properties of the floor material (including the substrate), which is used in the test combustion chamber to ignite the floor material placed horizontally and exposed to the tilted thermal radiation field with a small flame. It can be used to evaluate the material flame Communication ability.
Standards
ASTM E648-15 Standard test method for critical radiant flux of floor-covering systems using radiant heat energy source
BS EN ISO Reaction to fire test for flooring-Part1: Determination of the burningbehavior using a radiant heat source
GB/T 11785-2005 Determination of Combustion Performance -Floor material radiation heat source method
