Radiant Panel (ISO 9239-1)

This is some text inside of a div block.

This part of ISO 9239 specifies a method for assessing the wind-opposed burning behavior and spread of flame of horizontally mounted flooring exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. This test method is used to measure the critical radiant flux of floor covering system exposed to a flaming initiation source in graded radiant heat environment within a test chamber.This method is applicable to all types of flooring, e.g. textile carpet, cork, wood, rubber and plastics covering as well as coatings, exposed attic floor cellulose insulation.
