Test Type 4 – Fire Performance of Cylinder Subjected to a Steady 300 kW RoomFireIn Test Type 4, a heating appliance with the composite cylinder, and an additional compositecylinder as a spare cylinder, were tested in an NFPA 286 configuration test room with a steady300 kW fire in one corner. In this test, the test room was lined with gypsum wallboard. Theappliance was located in the opposite corner facing the open doorway with the spare cylinderstanding next to it. During the test, the pressures in the gas cylinders were measured and thecylinders were observed to detect any ignition of the cylinder material.The detailed test plan is as follows:• Hazard Assessment Scenario— Contribution to the fire hazards from a full spare cylinder and appliance whenexposed to radiation from a 300 kW flame— Instrumented NFPA 286 size room— Fire in room controlled by a 300 kW propane gas burner• Test Arrangement— NFPA 286 Test Room as shown in Figure 15— Propane gas ignition source (300 kW burner) in corner— Appliance placed in the corner opposite the fire radiation source− Appliance switched off to maximize pressure build-up− Vertical orientation− Cylinder filled to approximately 1/3 of the cylinder capacity— Spare cylinder− Located approximately 6 inches from the heater and 42.5 inches from the 300kW burner− Full spare cylinder— Gypsum board wall and ceiling materials• Duration of each test:— Approx. 30 minutes• Instrumentation— Cylinder pressure transducer, thermocouple tree (room center), ceilingthermocouples, cylinder thermocouples, video, digital photography• Data— Cylinder pressure and temperature, room temperature, video, photographyComposite Propane Cylinders 34February 2007for Indoor Use — Phase IIBattelle
