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 (tign), chemical ( Q˙chem), and convective ( Q˙c) heat release rates, mass loss rate ( m˙) and effective heat of combustion (EHC).

1.2 The following test methods, capable of being performed separately and independently, are included herein:

1.2.1 Ignition Test, to determine tign for a horizontal specimen;

1.2.2 Combustion Tes
