rials which melt and flow away from the direct impingement of heat flux and do not give a smoke emission, which is representative of current knowledge from real fire situations. The purpose of this method is to determine, under specific experimental conditions, the optical density of smoke produced by materials exposed vertically to a radiant heat source with or without the application of a pilot flame in a closed chamber (i.e. without air-change).
