| 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. |
