1.1 本指南的目的是提供液体和气体化学品的推荐清单，用于在测试项目中评估防护服材料。 1.2 使用这些测试化学品列表的测试程序得出的结果不用于防护服材料的明确表征。 1.3 测试化学品清单并不包括所有化学挑战；选择这些化学品代表广泛的液体和气体化学类别和性质。并非所有化学类别都有代表。除了本指南中推荐的化学品外，还应测试开发商、制造商或用户特别感兴趣的其他化学品。 1.4 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 具体危害陈述见第节 7 . 1.5 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 本指南建立了挑战化学品的推荐清单，以鼓励那些评估化学防护服材料的人测试常见的化学品。这些清单将有助于比较不同来源和不同材料的数据。5.2 本指南还可以为材料开发者或评估者筛选候选防护服材料提供服务。 5.3 适用于本指南使用的测试方法包括但不限于 F739 和 F903 . 5.3.1 气态化学品不得用于测试材料抗渗透性，因为测试方法 F903 仅用于测量液体渗透。 5.3.2 使用气态化学品对材料和结构元件（例如，接缝）的评价主要针对用于构造完全封装的防护服或旨在防止暴露于化学蒸汽或气体的其他衣物的那些材料。只有经过评估并证明有适当水平的气体和蒸汽向内或向外泄漏的蒸汽防护服才适用于蒸汽和气体防护。仅覆盖身体部分或没有防蒸汽封闭件、封闭件或与其他整体组件接口的防护服不能提供针对有害化学蒸汽和气体的防护。 附注1: 评估防护服套装的蒸汽防护性能的方法包括但不限于测试方法 F1052 和 F2588 . 5.4 本指南中任何化学品的存在并不意味着该化学品对保护工人免受化学危害有任何特殊意义。化学品旨在代表一系列化学类别、危害、物理特性和其他因素。从皮肤毒性或刺激的角度来看，并非所有化学物质都有意义。 附注2: 分类 F1186 是对化学品进行分类的一种方法。5.5 防护服材料对特定化学品或化学品列表的耐化学性并不推断该防护材料对其他化学品的耐化学性。

1.1 The purpose of this guide is to provide recommended lists of both liquid and gaseous chemicals for evaluating protective clothing materials in testing programs. 1.2 Results derived from testing programs using these lists of test chemicals are not intended for the definitive characterization of protective clothing materials. 1.3 The lists of test chemicals are not inclusive of all chemical challenges; the chemicals were chosen to represent broad ranges of liquid and gaseous chemical classes and properties. Not all chemical classes are represented. Other chemicals specifically of interest to the developer, manufacturer, or user should be tested in addition to those recommended in this guide. 1.4 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. A specific hazards statement is given in Section 7 . 1.5 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. ====== Significance And Use ====== 5.1 This guide establishes recommended lists of challenge chemicals to encourage those who evaluate chemical protective clothing materials to test chemicals in common. The lists will facilitate the comparison of data from different sources and for different materials. 5.2 This guide may also serve material developers or evaluators in screening candidate protective clothing materials. 5.3 Test methods applicable to the use of this guide include, but are not limited to, Test Methods F739 and F903 . 5.3.1 The gaseous chemicals shall not be used for testing material penetration resistance because Test Method F903 is for measuring liquid penetration only. 5.3.2 Evaluation of materials and construction elements (for example, seams) using the gaseous chemicals is primarily intended for those materials used in the construction of totally encapsulating protective suits or other clothing items that are designed to prevent exposure to chemical vapors or gases. Only vapor-protective clothing that has been evaluated for and has demonstrated appropriate levels of inward or outward leakage against gases and vapor is appropriate for protection against vapors and gases. Protective clothing that only covers part of the body or that does not have vapor-resistant closures, closures, or interfaces to other ensemble components does not provide protection against hazardous chemical vapors and gases. Note 1: Methods to evaluate the vapor-protective performance of protective clothing ensembles include, but are not limited to, Test Methods F1052 and F2588 . 5.4 The presence of any chemical in this guide does not connote any special significance of the chemical for protecting workers from chemical hazards. The chemicals are intended to represent a range of chemical classes, hazards, physical characteristics, and other factors. Not all of the chemicals have significance from a skin toxicity or irritation perspective. Note 2: Classification F1186 is one approach to classifying chemicals. 5.5 Chemical resistance of a protective clothing material against a specific chemical or list of chemicals does not infer the chemical resistance of that protective material against other chemicals.
