1.1 Scope.
1.1.1 This standard shall apply to floor fire door assemblies of various materials and types of construction that are installed horizontally in openings of fire resistance–rated floor systems to retard the passage of fire.

Prevent the spread of fire and smoke with NFPA 288!
NFPA 288 is a test procedure developed for use in evaluating the performance of "floor fire door assemblies" when installed horizontally in fire resistance-rated floor systems. It measures the ability of the floor fire door assembly to remain in the opening and resist the passage of flame and heat with load carrying applications. (Softbound, 17 pp., 2007)
