ASTM F1506-2017 暴露在瞬間電弧和相關(guān)熱危險性下的電工防護服耐燃紡織材料性能規格 Standard Performance Specification for Flame Resistant and Arc Rated Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards

1.1 This performance specification identifies minimum flame resistance, construction, durability, and labeling requirements of textiles and subassemblies used in the manufacture of protective clothing worn by electrical workers to protect against exposure to momentary electric arc flash and related thermal hazards. 1.1.1 This performance specification does not address coated or laminated fabrics commonly used for rainwear applications in an arc hazard environment. 1.2 This performance specification defines minimum garment manufacturing and labeling requirements to allow users to select garments with appropriate electric arc ratings for protection from their determined electric arc flash hazard environment. 1.2.1 A prior determination of the electric arc flash hazard environment is required in order to select appropriate protective garments. This prior determination is outside the scope of this specification. 1.2.2 The care and maintenance requirements for electric arc flash protective garments are outside the scope of this standard. 1.3 This standard should be used to evaluate and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions. It should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. 1.3.1 The results of this evaluation may be used as elements of a fire-risk assessment that takes into account all of the factors that are pertinent to an assessment of the fire hazard of a particular end use. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 The following precautionary caveat pertains only to the test methods portion, Section 7, of this performance specification: This standard does not purport to address all of the safety concerns, if any, associated
