This International Standard specifies a test method that simulates a fire that under well ventilated conditions starts in a corner of small room with a single open doorway. The method is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source. A standard ignition source is specified, but other alternatives are allowed. It should, however, be noted that the type, position and heat output of the ignition source will considerably influence the fire growth. The method is especially suitable for products that for some reason cannot be tested in a small laboratory scale, for example thermoplastic materials, the effect of an insulating substrate, joints, surfaces with great irregularity. The method is not intended to evaluate the fire resistance of a product.
A test performed in accordance with the method specified in this International Standard provides data for the early stages of a fire from ignition up to flashover.
