    Help ensure you are up to date with the latest methods of testing fire door assemblies by referencing NFPA 252, 2022 edition.

    Fire doors play a critical role in helping to protect lives and property by slowing the spread of flames, heat, and gases through door openings in fire-resistive walls. NFPA 252, Standard Methods of Fire Tests of Door Assemblies, details the appropriate procedures for conducting fire and hose stream tests to determine the degree in which assemblies provide sufficient resistance to fire and assessing suitability when protection over a particular time is necessary.

    An essential document for manufacturers and testing laboratories, the standard offers provisions for comparing fire door assemblies to appraise respective performance under standard fire conditions.

    NFPA 252 content includes:

    • General administration, definitions, and referenced publications
    • Control of fire test, including temperature-time curve, furnace temperatures, and unexposed surface temperatures
    • Fire door assembly construction and size, mounting, clearances, and test wall
    • Conduct of fire test and hose stream test
    • Performance criteria for fire door assemblies, including swinging and sliding doors
    • Reporting requirements and annex material covering explanatory, commentary, and informational references

    The 2022 edition is your guide to industry-recognized provisions for fire testing door assemblies.

    NFPA 252, Standard Methods of Fire Tests of Door Assemblies, is the required test when applying NFPA 80, Standard for Fire Doors and Other Opening Protectives. The revised 2022 edition of NFPA 252 features editorial revisions and new definitions for fire protection rating and fire-resistance rating.

    Accurately assess the capacity of fire doors to stop the passage of flame, heat, and gases.

    NFPA 252, Standard Methods of Fire Tests of Door Assemblies, provides the guidance you need to help confirm assemblies are designed, manufactured, and tested to perform as intended. Make sure you are working with the most current information by ordering your copy today. (Print, 24 pp., 2022)

    2017 Edition

     

    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®.

    • Control of fire test
    • Conduct of tests
    • Fire test
    • Hose stream test
    • Performance criteria
