摘要:

从标准修订的必要性出发,详细介绍了国家标准GB 14907-2018《钢结构防火涂料》的修订背景、编制原则、新旧标准主要内容对比。新标准具有以下特点:新增了烃类(HC)火灾升温条件、隔热效率试验方法及衰减量性能要求、耐紫外线辐照性能要求和试验方法、pH 值的要求和试验方法;将耐火性能进行了分级;耐火性能技术指标新增了试件温度的要求,修订了试件的承载能力;引入了“截面系数”概念。

Abstract: Starting from the necessity of standard revision, this paper introduces the revision background, compilation principle and main technical content comparison of national standard GB 14907-2018 Fire resistive coatings for steel structures. The new standard has the following characteristics: hydrocarbon (HC) fire heating conditions, insulation efficiency test method and attenuation performance requirements, ultraviolet radiation resistance performance requirements and test methods, pH value requirements and test methods are added. The fire resistance performance is classified. The fire resistance technical indicator of the requirements of specimen temperature is added, and the bearing capacity of specimens is revised. The "section factor" is national introduced.

Key words: steel structure, fire retardant coating, fire resistance; notional standard
