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
