The GB/T 9978.8 - 2008 standard focuses on the special requirements of non-load-bearing vertical partition components in the fire resistance test of building components. It clarifies the key content such as heating conditions, test equipment, and judgment standards of such components during the fire resistance test, and standardizes the evaluation process from the aspects of integrity and heat insulation. This standard provides a basis for the construction industry to accurately determine the fire resistance performance of non-load-bearing vertical partition components, and helps manufacturers control the mass of products to ensure that they effectively play a role in fire separation and improve the overall fire safety level of buildings.
