GB/T 24267-2009 specifies the classification, technical requirements, test methods, and inspection rules for sealants used in building joints to resist fire penetration and smoke spread. It is applied in construction projects for sealing gaps around doors, windows, curtain walls, and pipe penetrations where fire-rated assemblies require maintained integrity and insulation under fire conditions. This standard ensures sealants meet performance criteria for flame spread, smoke production, and heat transmission in fire-resistant building applications.
