Fire Propagation Apparatus

  • BS 476-6
Fire Propagation Apparatus, relate to BS 476-6, specifies a method of test, the result being expressed as a fire propagation index, that provides a comparative measure of the contribution to the growth of fire made by and essentially flat material, composite or assembly. It provides data suitable for comparing the end-use performances of essentially flat materials, composites or assemblies, which are used primarily as the exposed surfaces of walls and ceilings.
Fire Propagation Index Apparatus
