2、mmediately following the designation indicates the year oforiginal adoption or,in the 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.Scope*1.1 This is
3、 a fire-test-response standard.1.2 This test method provides a means to measure the heatreleased and smoke obscuration by burning the electricalinsulating materials contained in electrical or optical fibercables when the cable specimens,excluding accessories,aresubjected to a specified flaming ignit
4、ion source and burn freelyunder well ventilated conditions.Flame propagation cabledamage,by char length,and mass loss are also measured.1.3 This test method provides two different protocols forexposing the materials,when made into cable specimens,to anignition source(approximately 20 kW),for a 20 mi
5、n testduration.Use it to determine the heat release,smoke release,flame propagation and mass loss characteristics of the materialscontained in single and multiconductor electrical or opticalfiber cables.1.4 This test method does not provide information on thefire performance of materials insulating
6、electrical or opticalfiber cables in fire conditions other than the ones specificallyused in this test method nor does it measure the contribution ofthe materials in those cables to a developing fire condition.1.5 Data describing the burning behavior from ignition tothe end of the test are obtained.
7、1.6 This test equipment is suitable for measuring the con-centrations of certain toxic gas species in the combustion gases(see Appendix X4).1.7 The values stated in SI units are to be regarded asstandard(see IEEE/ASTM SI-10).The values given in paren-theses are mathematical conversions to inch-pound
8、 units thatare provided for information only and are not consideredstandard.1.8 This standard measures and describes the response ofmaterials,products,or assemblies to heat and flame undercontrolled conditions,but does not by itself incorporate allfactors required for fire hazard or fire risk assess
