1.1 ,This fire-test-response standard determines and quantifies material flammability characteristics, related to the propensity of materials to support fire propagation, by means of a fire propagation apparatus (FPA). Material flammability characteristics that are quantified include time to ignition (t_ign), chemical ( Q˙,_chem), and convective ( Q˙,_c) heat release rates, mass loss rate ( m˙,) and effective heat of combustion (EHC).
