1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter.1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heating fluxes. The specimen is oriented horizontally, and a spark ignition source is used.1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354.1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included.1.5 The values stated in SI units are to be regarded as
