  • Description

    Help increase fire protection of roof decks by referencing the most current NFPA provisions for testing of roofing assemblies.

    NFPA® 276, Standard Method of Fire Test for Determining the Heat Release Rate of Roofing Assemblies with Combustible Above-Deck Roofing Components, provides information and guidance to help mitigate risks and help keep people and property safer. The standard describes a method for determining the heat release rate from below the deck of roofing assemblies that have combustible above-deck roofing components when they are exposed to a fire from below the roof deck.

    NFPA 276 covers the following topics:

    • Instrumentation specification
    • Furnace verification and calibration
    • Test specimens and conditioning
    • Conducting tests
    • Reporting of fire test results

    2019 Edition

    Mitigate roof deck fire hazards. Reliably determine the heat release rate of roofing assemblies with the test method presented in NFPA 276.

    Fires involving roof deck assemblies have resulted in significant losses and damage to buildings that had other fire protection systems in place. That's why testing laboratories and manufacturers of construction and roofing materials need the latest edition of NFPA 276, Standard Method of Fire Test for Determining the Heat Release Rate of Roofing Assemblies with Combustible Above-Deck Roofing Components. NFPA 276 describes a method for determining the heat release rate from below the deck of roofing assemblies that have combustible above-deck roofing components when the assemblies are exposed to a fire from below the roof deck.

    The test method presented in NFPA 276 is based on the substitution method for measuring the heat release rate by using an auxiliary fuel (propane) to provide the surrogate heat. Requirements include instrumentation specification, and furnace verification and calibration. Provisions also address reporting of fire test results. (Print, 16 pp., 2019)

     

    2015 Edition

    The 2015 NFPA 276 offers laboratories a reliable way to determine the heat release rate of roofing assemblies.

    NFPA 276, Standard Method of Fire Test for Determining the Heat Release Rate of Roofing Assemblies with Combustible Above-Deck Roofing Components describes a method for determining the heat release rate from below the deck of roofing assemblies that have combustible above-deck roofing components when the assemblies are exposed to a fire from below the roof deck.

    NFPA 276 is based on FM 4450, "Approval Standard for Class 1 Insulated Steel Roof Decks."

    Used by testing laboratories and manufacturers of construction and roofing materials, NFPA 276's test method is based on the substitution method for measuring the heat release rate by using an auxiliary fuel (propane) to provide the surrogate heat. Requirements include instrumentation specification, and furnace verification and calibration. Provisions also address reporting of fire test results. (Softbound, 12 pp., 2015)
