Evaluate the ability of fire doors to resist the passage of flame, heat, and gases with the latest testing provisions in the new NFPA 252.

Revised with more guidance, the 2017 edition of NFPA 252: Standard Methods of Fire Tests of Door Assemblies outlines methods of fire testing door assemblies that testing laboratories and manufacturers can use to determine assembly suitability when fire resistance of a specific duration is required. 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.

NFPA 252 is also the required test for application of NFPA 80: Standard for Fire Doors and Other Opening Protectives, which is now an enforced requirement based on the U.S. Centers for Medicare & Medicaid Services (CMS) official adoption of the 2012 edition of NFPA 101®: Life Safety Code®.
