Flammability Testing Equipment Flooring Radiant Heat Flux Test
This test method is used to measure the critical radiant flux of
horizontally-mounted floor covering systems exposed to a flaming
ignition source in a graded radiant heat environment, within a test
chamber. It can also be used to measure this same critical radiant
flux for exposed attic floor cellulose insulation.Suitable for all
kinds of flooring materials. Such as: textile carpets, soft wood,
wood, rubber and plastic flooring and floor boards spray material.
The apparatus can be reacted combustion performance flooring
including the use of a substrate, backing material, backing
material, or flooring materials other changes are likely to affect
the test results, which is used to test and describe under
controlled conditions in the laboratory, shop combustion
characteristics to the material paired heat of reaction to fire.
