GB/T 9978.9 - 2008 standard specifies the special requirements for non-load-bearing ceiling components in the fire resistance test of building components. This standard specifies the heating conditions, Installation methods, test equipment and other details of such components in the test, and sets evaluation criteria from the aspects of integrity and thermal insulation. The construction industry can use this to accurately test the performance of non-load-bearing ceiling components in fires, help manufacturers optimize products, and ensure that the ceiling can prevent the spread of fire in the event of a fire, protect the lower space, and provide strong support for improving the fire safety level of buildings.
