Reaction to fire tests. Horizontal surface spread of flame on floor-covering systems - Determination of the burning behaviour using a radiant heat sourceThis International Standard specifies a method for assessing the wind opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required. This method is applicable to all types of flooring e. g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings.
