NFPA 276 – Standard Method of Fire Test for Determining the Heat Release Rate of Roofing Assemblies with Combustible Above-Deck Roofing Components
۲۰۲۳ Edition
Chapter 1 Administration
۱-۱* Scope.
۱-۱-۱* This standard desc1-ibes 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.
۱-۱-۲ The performance of the above-deck roofing assembly is evaluated by determining the heat release rate below the deck of the roof test specimen.
۱-۱-۳* This 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 release rate.
۱-۲ Purpose.
۱-۲-۱* Test Method.
۱-۲-۱-۱ Two fire tests are conducted to determine the heat release rate of the test specimen as follows:
(۱) Fire exposure test
(۲) Evaluation test with auxiliary fuel
