Introduction:

Critical Radiant Flux of the main parameters of flooring materials evaluate the fire risk, and it characterizes the flooring material samples subjected to conditions at the thermal radiation from outside flame.

According ISO9239-1,2  requirements, and flooring heat radiating plate test is in the chamber, through a certain heat radiation environment, measure critical radiant floor coverings Combustion case value. Radiation can also be used to measure the critical value of attic floor cellulose insulation material.
