The GB/T 9978.5-2008 standard gives special requirements for load-bearing horizontal partition components in fire resistance tests of building components. It specifies the loading conditions and heating procedures of components in the test, and establishes performance judgment rules from the aspects of load-bearing capacity, integrity, and heat insulation. The standard provides a basis for the construction industry to accurately evaluate the fire resistance performance of such components, and helps production enterprises control the mass to ensure that the load-bearing horizontal partition components can not only maintain the structural load in the fire, but also effectively prevent the vertical spread of fire, and ensure the safety of building space and the effectiveness of fire protection zoning.
