2025 NFPA 80 Standard for Fire Doors and Other Opening Protectives

NFPA 80, Standard for Fire Doors and Other Opening Protectives 2025 edition establishes mandatory requirements for the installation, inspection, testing, and maintenance of fire door assemblies and other opening protective systems. Coverage spans fire door assemblies, fire windows, dampers, fabric safety curtains, and protective curtain assemblies — providing general performance requirements for all types and configurations. The standard is referenced in NFPA 101, Life Safety Code, and in building and fire codes across the United States and internationally, making it the primary reference for anyone responsible for the installation or ITM compliance of fire-rated opening protectives. The 2025 edition delivers broad updates across door types, damper requirements, glazing, clearances, and a new chapter for horizontal fire door assemblies.

Required by fire protection engineers, architects, building inspectors, AHJ officials, door and hardware contractors, ITM service providers, and facility managers responsible for the installation, inspection, testing, and maintenance of fire door assemblies and opening protectives in commercial, institutional, and industrial occupancies.
