Defines a series of ignition sources for use in determining the ignitability of materials, composites and assemblies which are subjected to direct impingement of flames of different size and intensity, but without impressed irradiance. For use in isolation or with the specific test procedure. Gives the ignitability of a material, composite or assembly and is not intended for assessment of any other fire parameter (such as flame spread). Also consideres the possibility of the material, composite or assembly causing secondary ignition of other materials, by observing burning droplets of debris.
