Official document scope
What does NFPA 252 address?
Provisions prescribe standardized fire and hose stream test procedures that apply to fire door assemblies intended to be used to retard the spread of fire (flame, heat, and hot gases) through door openings in fire-resistive walls. The Standard allows different fire door assemblies to be compared with each other in order to evaluate their relative performance as measured against a standard fire experience.
