1.1 本性能规范确定了最低性能要求，以确定 （a） 织物的电弧额定值， （b） 织物和组件的阻燃性， （c） 织物和组件的机械耐久性， （d） 最低服装结构和性能要求，以及 （e） 暴露在火焰和电弧中的工人所穿的完整防护服的服装标签要求。 1.1.1 服装标签的最低要求旨在为最终用户提供足够的信息，以选择具有适当弧度等级的服装。 1.1.2 最终用户需要进行评估，以确定危险等级和防护服针对其个人危险所需的电弧额定值。 1.1.2.1 最终用户风险评估不在本标准范围内。 1.2 本性能规范不涉及电弧危险环境中常用于雨衣应用的涂层或层压防护服。规范中详细说明了与此类防护服相关的性能要求 F1891 . 1.3 本性能规范不涉及手部保护。与手部防护相关的性能和测试要求详见OSHA 1910.138规范 D120型 ，以及试验方法 F2675/F2675M . 1.4 清洗电弧闪光防护服的护理和维护要求不在本标准范围内。 参考指南 F1449 或 F2757 与工业或家庭洗钱有关。 1.5 本标准应用于评估和描述受控实验室条件下材料、产品或组件对热和火焰的响应特性。它不应用于描述或评估实际火灾条件下材料、产品或组件的火灾危险或火灾风险。 1.5.1 该评估结果可作为火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。 1.6 以国际单位制表示的数值应视为标准。 括号中给出的值仅供参考。 1.7 以下预防性警告仅适用于试验方法部分第节 7. ，本性能规范: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This performance specification identifies minimum performance requirements to determine the (a) arc rating of fabrics, (b) flame resistance of fabrics and subassemblies, (c) mechanical durability of the fabrics and subassemblies, (d) the minimum garment construction and performance requirements, and (e) the garment labeling requirements for the completed protective clothing worn by workers exposed to flames and electric arcs. 1.1.1 The minimum requirements for garment labeling are intended to provide end users with adequate information to select garments with the appropriate arc rating. 1.1.2 End users are required to perform an assessment to determine the level of hazard and the required arc rating of the protective clothing for their individual hazards. 1.1.2.1 The end user risk assessments are outside the scope of this standard. 1.2 This performance specification does not address coated or laminated protective clothing commonly used for rainwear applications in an arc hazard environment. Performance requirements related to this category of protective clothing are detailed in Specification F1891 . 1.3 This performance specification does not address hand protection. Performance and test requirements related to hand protection are detailed in OSHA 1910.138, Specification D120 , and Test Method F2675/F2675M . 1.4 The care and maintenance requirements for laundering electric arc flash protective clothing are outside the scope of this standard. Refer to Guides F1449 or F2757 related to industrial or home laundering. 1.5 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. 1.5.1 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. 1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.7 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 with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
