National Fire Protection Association (NFPA) 80, Standard for Fire Doors and Other Opening Protectives, is referenced by the International Building Code (IBC), International Fire Code (IFC), NFPA 101, Life Safety Code, and other codes and standards. NFPA 105, Standard for the Installation of Smoke Door Assemblies and Other Opening Protectives, addresses smoke doors and is also referenced in these publications.
Some fire door requirements are included within the applicable building or fire code, but NFPA 80 and 105 are referenced for many of the detailed requirements. For product-specific issues, the manufacturer’s listings must be referenced. For example, to find out the maximum fire door size available from a particular manufacturer, one should consult Underwriters Laboratories’ UL Building Materials Directory or Intertek’s Warnock Hersey Mark Directory.
