1、Designation:E218716An American National StandardStandard Test Method forMeasuring the Ignition Strength of Cigarettes1This standard is issued under the fixed designation E2187;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe most common initiating event in a fatal fire in the United States is the dropping of a lit cigaretteonto a bed or p
3、iece of upholstered furniture.The cigarette coal heats the furnishing materials to thepoint where smoldering combustion begins,perhaps followed by a transition to flaming combustion.Since limiting the frequency of ignitions is a principal approach to reducing fire loss,it is desirableto establish a
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
5、-response standard provides a standardmeasure of the capability of a cigarette,positioned on one offour standard substrates,to generate sufficient heat to continueburning and thus potentially cause ignition of bedding orupholstered furniture.1.2 This method has value as a predictor of the relativepr
6、opensity of a cigarette to ignite upholstered furnishings.1.3 This method is applicable to cigarettes that burn alongthe length of a tobacco column.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 This standard is used to
7、 measure and describe theresponse of materials,products,or assemblies to heat and flameunder controlled conditions,but does not by itself incorporateall factors required for fire hazard or fire risk assessment of thematerials,products,or assemblies under actual fire conditions.1.6 This standard does
