1、Designation:F153410Standard Test Method forDetermining Changes in Fire-Test-Response Characteristicsof Cushioning Materials After Water Leaching1This standard is issued under the fixed designation F1534;the number immediately following the designation indicates the year oforiginal adoption or,in the
2、 case of revision,the year 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.1.Scope1.1 This fire-test-response test method covers a procedurefor leaching cushioning materials with
3、water and determiningchanges in two specific fire-test-response characteristics:(1)the surface flammability,in accordance with Test MethodD3675,and(2)the specific optical density of smoke generated,in accordance with Test Method E662.1.2 In view of the wide variation in potential serviceconditions,i
4、t is likely that results of this leaching test will notgive a direct correlation with service performance for allapplications.However,the test method yields comparative dataon which to base judgments as to expected service of cushion-ing materials and is useful in research and development work.1.3 T
5、he values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 This standard is used to measure and describe theresponse of materials,products,or assemblies to heat andflame under controlled conditions,but does not by itselfincorporate all
6、factors required for fire hazard or fire riskassessment of the materials,products,or assemblies underactual fire conditions.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-p

16、iscussionA fire-test-response characteristic canbe influenced by variable characteristics of the heat source,such as its intensity,or of the burning environment,such asventilation,geometry of item or enclosure,humidity,or oxygenconcentration.It is not an intrinsic property such as specificheat,thermal conductivity,or heat of combustion,where thevalue is independent of test variables.A fire-test-responsecharacteristic may be described in one of several terms.Smokegeneration,for example,may be des
