1、Designation: D4391 93a (Reapproved 2013)1Standard 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 r

2、evision. A number in 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

A bibliography ofrelated literature is given in Appendix X1.1NOTEThe term “exposure energy to thermal end point” was added editorially in May 2013.afterflame, npersistent flaming of a ma

D13.92 D4391afterglow, nglow in material after the removal of an externalignition source or after the cessation (nat

(See also flame, glow, and smol-dering.)afterglow time, nthe time afterglow continues after thecessation of flaming or after removal of the ignition source.D13.92 D4391burning behavior, nall the changes that take place whenmaterials or products are exposed

8、fined. This term isimplied in the Standard for the Flammability of ClothingTextiles (16 CFR Part 1610) under the Flammable FabricsAct (15 USC 1191, et seq.) from which a meaning can beinferred.

13、ame resistance exhibited by a specific material duringtesting may vary with different test conditions.flame resistant, adjhaving flame resistance.DISCUSSION“Flame resistant” is the government mandated descrip-tion for certain products that meet established governmental confor-mance standards or spec

14、ifications when the product is tested by aspecific method. Where no conformance standards exist, “flame resis-tant” is a relative term and is used to compare one material to another.flame retardant, adjnot defined. This term should not beused as an adjective except in the terms “flame-retardant-trea

Aspects of glow not involving combustion are definedin dictionaries of general terms.heat durability, nthe extent to which a materi
