NFPA 80 / NFPA 105 schedule
Every requirement carries its code section and the edition it was verified against. ★ = qualified in-house under the national code, but licensing commonly required locally — confirm with your AHJ.
Fire and smoke damper testing comes from NFPA 80 and NFPA 105 — consensus standards, not law. They bind your building only where your state, AHJ, accreditor or insurer has adopted them, at the edition adopted, and only where a duct penetrates a rated assembly. Hospitals certified by CMS are surveyed against the 2012 Life Safety Code, which references earlier editions of NFPA 80 and NFPA 105 than the 2022 edition cited below; confirm with your surveyor or AHJ which edition and which interval applies to you, and whether a waiver declaration is expected at your entrance conference. The 6-year hospital cycle is a conditional allowance, not an automatic one. Neither standard fixes how long you keep the record — your state, accreditor or insurer sets that, which is why the table says so rather than printing a number. Testing is by a qualified person; whether that means a licensed contractor is a local licensing question, and the damper’s listing and the manufacturer’s instructions govern how it is tested.
