1、Designation: D4391 161Standard Terminology Relating toThe Burning Behavior of Textiles1This standard is issued under the fixed designation D4391; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i

2、n parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.The definitions in this standard have been approved by the Society and are included in D123 “Terminology Relating to Textiles”. Theyare published as a sepa

A bibliography ofrelated literature is given in Appendix X1.1NOTETerms from Test Method D1230 were added in April 2016.afterflame, npersistent flaming of a material after the igni-tion source has been remo

D13.92 D4391afterglow, nglow in material after the removal of an externalignition source or after the cessation (natural or induced) offlaming of the material. (Se

6、 flame.DISCUSSIONBase burn is also known as base fabric ignition orfusing. The base burns used to establish a Class 3 fabric are those burnsresulting from surface flash that occur on specimens in places otherthan the point of impingement when the warp and fill yarns of a raisedsurface textile fabric

Base burns can be identifiedby an opacity change, scorching on the reverse side of the fabric, orwhen a physical hole is evident.burn time, nthe time elapsed from ignition until the stopthread is severed as measured by the timing mechnsim of thetest apparatus.burning behavior, n
