摘　　要：防火封堵材料标准的变化对生产制造、应用、检验都有重要影响,依据历次标准的实施过程来看,在新标准的初始实施阶段,特别是变化比较大的情况下,总会产生一些对标准理解不够充分、理解混乱甚至错误使用标准的现象发生,给相关从业者带来损失。为使相关从业者更好的理解、正确使用新标准,本文对新标中影响较大的增加部分:电缆填充率、管道贯穿率、使用场所、多组分封堵材料、产烟毒性、气密性、冲水试验性能;标准变化部分:火灾环境条件、试验升温条件、炉内压力条件、试件制作、综合判定准则,结合工程应用、现代建筑要求、防烟灭火救援需要、检验的变化、与其他标准的关联等作了进一步的分析论述与解读,并对新标指导下产品的生产、使用、检验作出了探讨。Changes in standards for firestop material have an important impact on production,application,and testing.According to the previous implementation process of standards,in the initial implementation stage of the new standard,especially in the case of large changes,there will always be some insufficient understanding,confusion of understanding,and even misuse of standards,which bring losses to relevant practitioners.In order to make relevant practitioners better understand and correctly use the new standard,this paper further analyzes and interprets the standard:the newly added part with a greater impact includes percent for cable penetration area,percent for pipe penetration area,use sites,multi-component sealing materials,smoke toxicity,air tightness,flushing test performance;the changes of the standard include fire environmental conditions,test temperature conditions,furnace pressure conditions,specimen production,comprehensive judgment criteria.Combined with engineering applications,modern building requirements,smoke prevention and rescue needs,changes in inspection,and correlation with other standards,the paper discusses the production,use,and inspection of products following the guidance of the new standard.
