In this test,the test room was lined with gypsum wallboard. The appliance was located in the corner facingthe open doorway. In one test, an additional spare cylinder, positioned next to the heater, wasexposed to the igniter. The increases in temperatures and heat flux in the test room, as well aspressure in the gas cylinder were measured.The data from these tests are summarized in Table 9.Test Type 3 TestsIn tests making up Test Type 3, the fire performance of the heating appliance with composite gascylinder was assessed in a room fire scenario that grows to flashover conditions. In this test suite,the test room was lined with medium density fiberboard. The heating appliance incorporating acomposite gas cylinder was positioned against the wall facing the open doorway. A 300 kW or a40-160 kW propane burner located in the corner of the room was used to ignite the mediumdensity fiberboard resulting in flashover conditions in the test room. In one test, an additionalspare cylinder was positioned next to the heater. The increases in temperatures, ensuing from thefire growth, were measured and the performance of the heating appliance was assessed.The results from Test Type 3 are provided in Table 10.Composite Propane Cylinders 38February 2007for Indoor Use — Phase IIBattelle
