The scope of NFPA 80, Standard for Fire Doors and Other Opening Protectives, addresses the installation, inspection, testing, and maintenance of the opening protectives. Prior to applying the requirements of NFPA 80, one must first determine if a fire rated opening protective is required and what the required fire protection rating is of that opening.
And that's where NFPA 1, 101, and 5000 come into play.
All three of these documents contain a table (Table 184.108.40.206 in NFPA 1, Table 220.127.116.11 in NFPA 101, and Table 8.7.2 in NFPA 5000) in which the minimum fire protecton rating is provided based upon the fire resistance rating of a component that was mandated somewhere in the Code. For example, an occupancy chapter may mandate a 1 hour fire resistance rating for their corridors. The tables provided in the Codes state that based upon an exit access corridor with a 1 hour fire resistance rating, a 20 minute fire protection rated door is required. A 2 hour fire resistance rated exit enclosure requires a 90 minute fire protection rated door, etc.
The tables referenced above provide much more than just the minimum fire protection ratings. New to the 2012 editions of NFPA 1, NFPA 101, and NFPA 5000, these tables were expanded to include provisions for glazing size and labeling.
