Combustion Tests Under High Pressure Oxygen: Promoted Ignition Combustion Test Versus Metallic Disk Ignition Test

CODEN: JAIOAD

Abstract

Two different test apparatuses are used at BAM to evaluate the safety of oxygen components: First, the “promoted ignition combustion test” according to ASTM G 124 [1] and to EIGA IGC Doc 13/02/E [2], and second, the new “metallic disk ignition test” that has not been standardized yet. The standard test method ASTM G 124 allows a ranking of metallic materials for use at high pressure oxygen. However, the transfer of those test results to valves and fittings in real-life situations is rather complex. The “metallic disk ignition test,” developed at BAM, is more practice oriented and uses metallic disks of different thicknesses of the investigated material. A commonly used nonmetallic sealing ring is placed in front of this disk and serves as an igniter. This test array is then exposed to high pressure gaseous oxygen impacts in a standardized pneumatic impact tester according to DIN EN 1797 [3].
