4、test method for the propensity of a cigarette to ignite soft furnishings.This test methoduses standard substrates to determine the extent to which,as the substrate draws heat from thecigarette,the cigarette combustion remains strong enough to be capable of initiating a fire.1.Scope1.1 This fire-test
