適用范圍：This part of ISO 11925 specifies a series of ignition sources which can be used for the deter 〓ation of the ignitability of materials, composites and assemblies when subjected to direct impingement of flames of different size and intensity but without impressed irradiance. The sources may be used in isolation or with the test method specified. This test method determines the ignitability of a material, composite or assembly and is not designed to assess any other fire parameter (e.g. flame spread). The possibility of the material composite or assembly causing secondary ignition of other materials is also considered by the observation of burning droplets or debris which may be formed. NOTE — Secondary ignition of material in a growing fire situation can be addressed using ISO 5657 which assesses the ignitability of building products by irradiance.
