2、 of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the evaluation of heat transferof textile materials which are used as thermal barriers whenexpo
3、sed to a calibrated convective and radiant energy heatsource for 60 s.1.1.1 This standard is used to determine if the heat transferis sufficient to ignite flammable materials which are contiguousto the textile thermal barriers.1.2 This standard is used as a means to differentiate textilematerials.1.
4、3 This test method is not intended to measure the insula-tion properties of materials used in protective clothing.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem sh
