1.1 本文件规定了为保护航空航天产品免受静电放电和人员和服装释放的污染物而设计的特殊衣物（洁净室衣物）。特殊服装包括低绒工作服、鞋类和头套。 1.2 洁净室服装的功能是控制人们产生的污染物，并尽量减少服装中的污染物。 1.3 服装可选择两种面料。这两种类型都是固有的静电耗散材料，以防止可能损坏敏感硬件或在存在易燃蒸汽时引发爆炸的放电。指定用于“危险环境”的材料具有阻燃性，并为佩戴者提供额外保护。服装设计和面料的选择应基于用户在功能和环境要求方面的需求。 1.4 其他背景信息可在SD中找到- TR-91-26和IEST-RP-CC003.3。 1.5 本标准旨在符合ASTM防火标准政策。 2. 本标准中规定的可燃性试验应用于测量和描述织物在受控实验室条件下对热和火焰的响应特性，而不应用于描述或评估实际火灾条件下的织物。然而，测试结果可作为火灾风险评估的要素，该评估考虑了与受控环境区域作业火灾危险评估相关的所有因素。 1.6 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。组合两个系统的值可能导致不符合标准。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、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 document specifies special items of clothing (cleanroom garments) designed to protect aerospace products from electrostatic discharge and from contaminants released by personnel and garments. Special clothing includes low linting coveralls, footwear, and head covers. 1.2 The function of cleanroom garments is to contain the contaminants generated by people and to minimize contaminants from the garments. 1.3 Two types of fabrics can be selected for the garments. Both types are inherently static-dissipative materials to prevent electrical discharges that can damage sensitive hardware or initiate explosions in the presence of flammable vapors. The material specified for “hazardous environments” is flame resistant and provides additional protection to the wearer. Selection of garment design and fabric should be based on the user's needs with respect to functional and environmental requirements. 1.4 Additional background information can be found in SD-TR-91-26 and IEST-RP-CC003.3. 1.5 This standard is intended to be in compliance with the ASTM policy on Fire Standards. 2 Flammability tests specified in this standard should be used to measure and describe the properties of fabrics in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fabrics under actual fire conditions. However, results of the tests may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of operations in controlled environment areas. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 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.
