3、 in February 2004.1. Scope1.1 This performance specification covers the flame resis-tance of textile materials to be used for wearing apparel for useby electrical workers exposed to momentary electric arc andrelated thermal hazards.NOTE 1This performance specification does not cover coated fabricsco
4、mmonly used in rainwear.NOTE 2At present, a bench scale arc test for laboratory use is notavailable. It is the intent of the committee to continue the search for anacceptable laboratory test based on either an electric arc exposure or anacceptable alternative, which will form the basis of a modifica
5、tion of thisperformance specification.1.2 Materials used for basic protection levels are covered.1.3 Protective properties relate to thermal exposure frommomentary arc and associated exposure to open flame andradiant heat. (See Appendix X1.)1.4 This performance specification covers wearing apparelde
6、sign characteristics that relate specifically to protection fromexposure to momentary electric arc and that relate to the utilityof the wearing apparel.NOTE 3A number of other thermal test methods are under consider-ation and development and, when evaluated and proved effective byCommittee F18, will
7、 be incorporated in either this performance specifi-cation or an appropriate alternative test method or specification.1.5 This standard should be used to evaluate and describethe properties of materials, products, or assemblies in responseto heat and flame under controlled laboratory conditions. Its
8、hould not be used to describe or appraise the fire hazard orfire risk of materials, products, or assemblies under actual fireconditions.1.5.1 The results of this evaluation may be used as elementsof a fire-risk assessment that takes into account all of thefactors that are pertinent to an assessment
9、of the fire hazard ofa particular end use.1.6 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.7 The following precautionary caveat pertains only to thetest methods portion, Section 7, of this performance specifica-tion: This
10、standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.
