Over the last several years, the International Standards Organization (ISO) has developed standards which require pneumatic impact testing on valves, regulators, and other oxygen components used in Europe in medical, industrial, and commercial applications. The several standards involved all reference a test system designed by BAM and presented in ASTM STP 1267 by Binder, et. al. in their paper “A 500 BAR Gaseous Oxygen Impact Test Apparatus For Burn-Out Testing Of Oxygen Equipment.” This paper discusses another gaseous oxygen impact test system designed to conform to the ISO standards, and presents its performance characteristics in pneumatic impact testing. This paper also discusses the value of a component test method and considers some of the critical parameters that should be maintained in order to produce consistent test results with different test systems.
