Scope
This Technical Report provides a method for measuring the response of materials, products and assemblies exposed in vertical orientation to controlled levels of radiant heating with an external igniter.
This test method is used to determine the ignitability, heat release rates, mass loss rates, and visible smoke development of materials, products and assemblies under well ventilated conditions.
The heat release rate is determined by measurement of the oxygen consumption as determined by the oxygen concentration and flow in the exhaust product stream as specified in 11.1. Smoke development is quantified by measuring the obscuration of light by the combustion product stream.
Specimens are exposed to heating fluxes ranging from 0 kW/m to 50 kW/m. Hot wires are used as the ignition source.
This test method has been developed for material, product or assembly evaluations, mathematical modelling and design purposes. The specimen are tested in thicknesses and configurations representative of actual end product or system uses.
