6、 method 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 assessment of thematerials, products, or assemblies under actual fire conditions.1.3 The

7、values stated in SI units or other units shall beregarded separately. The values stated in each system may notbe exact equivalents; therefore, each system must be usedindependently, without combining values.1.4 This standard does not purport to address all of thesafety concerns, if any, associated w

Summary of Test Method4.1 A conditioned specimen of a protective clothing mate-rial is folded in half and placed in

30、 a sample holder with thefolded edge suspended over a gas flame.4.2 The specimen is exposed to the flame for a 3-s interval.4.2.1 If the material ignites during this exposure, the after-flame time, afterglow time, and burn distance of the specimenare measured and reported. Any observations of burnin

31、gbehavior are also reported. The test is then terminated.4.3 If the material does not ignite after the first exposure, thesame specimen is exposed to the flame for a 12-s interval. Theafter-flame time, afterglow time, and burn distance of thespecimen are measured and reported. Any observations ofbur

32、ning behavior are also reported.4.4 An alternative procedure is provided for conducting the12-s exposure only.5. Significance and Use5.1 This test method is intended to determine the ignitionresistance and burning characteristics of materials used inprotective clothing, where flame resistance is not

33、 the primaryform of protection designated.5.1.1 Flame resistance is a distinctive property of clothingitems designated for isolating parts of the body from antici-pated flame hazards. It is possible that protective clothingdesignated for isolation from other hazard, such as those forchemical or biol

34、ogical protection, neither have flame resistancenor isolate the wearer from flame hazards. This test method canbe used to evaluate the effects of flame impingement onprotective clothing where flame resistance is not the primaryobjective of protection.F 1358 00 (2005)25.1.2 When flame resistance is t

35、he primary protection of-fered by the protective clothing, alternative test methods can beused. A test method that is useful for evaluating flameresistance of textiles is Test Method D 6413. Index D 4723contains descriptions and guidance on other flammability testmethods for textiles.5.1.3 This test

36、 method is useful to determine the ignitionresistance and burning characteristics of materials used inprotective clothing not designated for flame resistance whenthe outer material surface is exposed to the flame. As such, itis particularly suited to protective clothing materials which arecomposed o

37、f different layers such as coated fabrics, laminates,or multilayer clothing systems.5.2 Correlation of data from this test method with theignition resistance and burning characteristics of protectiveclothing (not designated for flame resistance) under actual useconditions is not implied.6.

Attach either asolenoid or stopcock to the burner. The control valve (stopco

42、ckor solenoid) shall be capable of being fully opened or fullyclosed in 0.1 s.6.2.4 On the side of the barrel of the burner, opposite thepilot light, use a metal rod of approximately 3-mm 18-in.diameter spaced 13 mm 12 in. from the barrel and extendingabove the burner. The rod shall have two 8-mm 51
