1.1 本指南旨在帮助应用化学防护服的开发、规范和选择标准，最终目的是维护接触危险化学品的工人的安全和健康。 1.2 本指南对每个参考标准进行了简短描述，然后对这些标准的使用提出了具体建议。参考标准按以下标题组织:材料耐化学性、材料物理性能、接缝和闭合性能以及整体服装性能。 1.3 没有任何协议可以确保选择能保证工人保护的防护服。 测试的目的是生成数据和信息，以便选择最合适的衣服。归根结底，服装的选择是基于对现有信息的技术评估和对风险的专业评估。 1.4 以国际单位制或其他单位表示的数值应单独视为标准。每个系统中规定的值必须相互独立使用，不得以任何方式组合值。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.6 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====== 4.1 F23委员会和其他技术委员会管辖的标准可以单独使用，也可以作为化学防护服开发、选择、规范和使用的综合协议的一部分。 4.2 这些标准旨在以一致、可比较的方式请求、生成和报告信息。 4.3 建议的评估和测试方法仅为推荐指南。测试方法提供了在标准条件下评估化学防护服的程序，以便进行比较。 4.4 有关服装性能的信息必须与专业判断和对服装应用的清晰了解相结合，才能为工人提供最佳保护。所有化学防护服的使用都必须基于危险评估，以确定接触化学品和其他危险的风险。根据29 CFR 1910.132进行危险评估。 4.5 在危险材料紧急情况下使用的化学防护服应根据NFPA 1991《蒸汽标准》进行评估并符合该标准- 危险材料紧急情况下的防护服，或NFPA 1992，危险材料紧急事件下的液体飞溅防护服和防护服标准，视紧急情况类型而定。对于恐怖主义事件期间涉及释放化学制剂的紧急情况，应根据NFPA 1994《化学/生物恐怖主义事件防护服标准》对化学防护服进行评估，并符合NFPA 1994《化学品/生物恐怖主义事故防护服标准。 4.6 《实践》中提供了化学防护服标签的建议 F1301飞机 ，《实践》中提供了实施化学防护服计划的建议 第1461页 ，并在实践中提供了编写护理和维护说明的建议 2006年2月 。 4.7 附录X1 是如何将几个参考标准结合到一个协议中，为给定的应用选择最合适的化学防护服的例子。简单地说，这个过程就是定义申请的要求，然后（通过测试）淘汰那些不合适的候选人。 4.8 附录X2 提供了将美国标准与欧洲和国际标准进行交叉引用的图表。该图表仅显示了测量相同性能或评估类似化学防护服的类似标准，并不意味着不同测试的结果具有可比性。

1.1 This guide is intended to aid in the application of standards for the development, specification, and selection of chemical protective clothing with the ultimate goal of maintaining the safety and health of workers who come into contact with hazardous chemicals. 1.2 This guide provides a short description of each referenced standard and then makes specific recommendations for the use of these standards. The referenced standards are organized under the following headings: Material Chemical Resistance, Material Physical Properties, Seam and Closure Performance, and Overall Clothing Performance. 1.3 No protocol can ensure the selection of protective clothing that guarantees worker protection. The purpose of testing is to generate data and information that will allow the selection of the most appropriate clothing. Ultimately, clothing selection is based on technical evaluation of available information and professional assessment of risk. 1.4 The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way. 1.5 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. 1.6 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 ====== 4.1 The standards under the jurisdiction of Committee F23 and other technical committees can be used individually or as part of an integrated protocol in the development, selection, specification, and use of chemical protective clothing. 4.2 The standards are intended as a means by which information can be requested, generated, and reported in a consistent, comparable manner. 4.3 The suggested evaluation and test methods are recommended guidelines only. Test methods offer procedures for evaluating chemical protective clothing at standardized conditions to allow comparison. 4.4 The information on clothing performance must be combined with professional judgment and a clear understanding of the clothing application to provide the best protection to the worker. All chemical protective clothing use must be based on a hazard assessment to determine the risks for exposure to chemicals and other hazards. Conduct hazard assessments in accordance with 29 CFR 1910.132. 4.5 Chemical protective clothing intended for use during hazardous materials emergencies shall be evaluated against and conform to NFPA 1991, Standard on Vapor-Protective Ensemble for Hazardous Materials Emergencies, or NFPA 1992, Standard on Liquid Splash-Protective Ensemble and Clothing for Hazardous Materials Emergencies, as appropriate for the type of emergency. For emergencies involving release of chemical agents during terrorism incidents, chemical protective clothing shall be evaluated against and conform to NFPA 1994, Standard on Protective Ensemble for Chemical/Biological Terrorism Incidents. 4.6 Recommendations for labeling chemical protective clothing are provided in Practice F1301 , recommendations for implementing a chemical protective clothing program are provided in Practice F1461 , and recommendations for preparing care and maintenance instructions are provided in Practice F2061 . 4.7 Appendix X1 is an example of how several of the referenced standards can be combined into a protocol to select the most suitable chemical protective clothing for a given application. Briefly, the process is one of defining the requirements of the application and then (by testing) eliminating those candidates that are unsuitable. 4.8 Appendix X2 provides a chart to cross reference U.S. Standards with European and International Standards. This chart shows only analogous standards for measuring the same property or evaluating the similar chemical protective clothing and does not imply that results from different tests will be comparable.
