    Abstract

    Eleven materials were evaluated for oxygen compatibility using the following test methods: heat of combustion (ASTM D 2015), liquid oxygen impact (ASTM D 2512), pneumatic impact (ASTM G 74), gaseous mechanical impact (ASTM G 86), autogenous ignition temperature by pressurized differential scanning calorimeter, and the determination of the 50 percent reaction level in liquid oxygen using silicon carbide as a reaction enhancer. The eleven materials evaluated were: Teflon® TFE, Vespel® SP-21, Krytox® 240AC, Viton® PLV5010B, Fluorel® E2160, Kel F® 81, Fluorogold®, Fluorogreen® E-600, Rulon® A, Garlock® 8573, nylon 6/6.
