The GB/T 9978.7-2008 standard specifies the special requirements for columns in fire resistance tests of building components. It specifies the key aspects of column loading in fire resistance tests, Linear dispersion, displacement measurement, etc., and specifies the test process from the dimensions of bearing capacity, integrity and thermal insulation. The standard provides a basis for the construction industry to accurately evaluate the fire resistance performance of columns, help manufacturers control the mass of products, and ensure that columns maintain structural stability in fires. It is of great significance to ensure the overall safety of buildings and prevent structural collapse in fires.
