| Abstract: | Startingfrom the necessity of standard revision, this paper introduces the revisionbackground, compilation principle and main technical content comparison ofnational standard GB 14907-2018 Fire resistive coatings for steel structures. The new standard has the followingcharacteristics: hydrocarbon (HC) fire heating conditions, insulationefficiency test method and attenuation performance requirements, ultravioletradiation resistance performance requirements and test methods, pH valuerequirements and test methods are added. The fire resistance performance isclassified. The fire resistance technical indicator of the requirements ofspecimen temperature is added, and the bearing capacity of specimens isrevised. The section factor is national introduced. |
