Standard Methods of Fire Tests of Door Assemblies
The next edition of this standard is now open for Public Input (formerly proposals).
What is NFPA 252?
This standard safeguards lives and property by outlining methods of fire testing door assemblies that testing laboratories and manufacturers can use to determine the degree of fire protection provided by such assemblies and assess their suitability when fire resistance of a specific duration is required.
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.
