Test Type 1 Test Setup.Tests were conducted on the two designs of empty cylinders positioned vertically and exposed tothe standard test igniter. The heat and smoke release rates from the burning cylinders weremeasured. Visual observations of the burning, including any melting and dripping was recorded.The detailed test plan is as follows:• Hazard Assessment Scenario— Fire hazard of cylinder material assembly exposed to small ignition/heat sources− Sample tested in vertical orientation− 2 tests per cylinder (empty) x 2 cylinder types = 4 tests− Test duration: approx. 30 minutes• Ignition Source— Half standard igniter• Instrumentation— Heat release instrumentation (total and convective), video, digital photography• Test Duration— Approximately 30 minutes• Data— Heat release rate, video, digital photographsComposite Propane Cylinders 29February 2007for Indoor Use — Phase IIBattelle

In this test, the test roomwas lined with gypsum wallboard. The appliance was located in the corner facing the opendoorway. In one test, an additional spare cylinder, positioned next to the heater, was exposed tothe igniter. The increases in temperatures and heat flux in the test room, as well as pressure in thegas cylinder were measured.The detailed test plan is as follows:• Hazard Assessment Scenario— Fire hazard from mal-functioning appliance which would result in small localizedfire in an occupancy• Instrumented NFPA 286 size room— 12 x 8 x 8-ft room with a single 2-ft 6-in. by 6 ft. high doorway• Ignition source applied to cylinder in the appliance— 3 in. diameter x 3 in length cotton gauze bundle soaked with gasoline• Test Arrangement— Standard NFPA 286 Test Room as shown in Figure 13— Partially (50%) and properly filled gas cylinders (vertical and horizontalorientations)— Ignition source applied to cylinder in the appliance— Gypsum board wall and ceiling materials• Duration for each Test— Approx. 30 minutes• Instrumentation— Cylinder pressure transducer, thermocouple tree (room center), ceilingthermocouples, heat flux gauges, video, digital photography• Data— Cylinder pressure, room temperature, radiation from the fire, video, photographyComposite Propane Cylinders 30February 2007for Indoor Use — Phase IIBattelle
