摘　　要：为厘清化学防护服国家标准修订后的情况,通过分析我国化学防护服国家标准发展历史,研究国外化学防护服标准,重点针对修订后的GB 24539—2021《防护服装化学防护服》的变化,从化学防护服的分类、性能要求、试验方法等方面对该标准加以解读。分析发现:GB 24539—2021将相关标准进行整合,对化学防护服的分类进行了较大的调整和更新,删除了非气密型化学防护服-ET,增加了气密型化学防护服、有限泼溅化学防护服和织物酸碱类化学防护服;相应地,性能要求也产生了较大变化,主要包括服装整体防护性能、服装面料防护性能及服装面料理化性能;GB 24539—2021中的大部分试验方法沿用了之前相关标准中的试验方法,但也进行了相应的改进和完善,主要包括试样预处理条件和试验环境条件、化学防护服向内泄漏率测试方法、化学防护服液密性能测试方法、化学防护服面料耐磨损性能测试方法和耐屈挠破坏性能测试方法。Objective This paper aims to clarify the situation after the revision of the national standard for chemical protective clothing to enhance correct understanding the new specifications of chemical protective clothing.It is expected that this work will help engineers make scientific and reasonable selection of chemical protective clothing from the perspectives of protective performance and service performance based on the hazard degree of chemicals in different job sites,to ensure the personal health and life and property safety of users.Method During developing the new national standard of chemical protective clothing in China,references were made to some foreign standards of chemical protective clothing,including International Organization for Standardization(ISO),European Committee for Standardization(CEN)and National Fire Protection Association(NFPA).Focusing on the changes in the revised GB 24539—2021"Protective Clothing:Chemical Protective Clothing",this paper interprets the standard from the aspects of classification,performance requirements and test methods.Results It is found that GB 24539—2021 integrated GB 24539—2009"Protective Clothing:General Technical Requirements for Chemical Protective Clothing",GB 24540—2009"Protective Clothing:Chemical Protective Clothing against Acids and Alkalis"and GB/T 29511—2013"Protective clothing:Chemical Protective Clothing for Solid Particles",and the classification of chemical protective clothing was greatly adjusted and updated by deleting the non-airtight chemical protective clothing-ET,and by adding the airtight chemical protective clothing,limited liquid spray chemical protective clothing and woven material liquid acid and alkali chemical protective clothing.Accordingly,the performance requirements were also changed greatly,these mainly including the overall protective performance of clothing,the protective performance of clothing fabrics and the physical and chemical properties of clothing fabrics.Among them,liquid leakage performance in the overall protec
