    This paper explains why this test was proposed for the qualification of oxygen compatible equipment such as valves, regulators, and flexible hoses. This was done to avoid the repetition of accidents or incidents reported by the industry in high pressure equipment. In addition, this paper explains how this test method was developed and improved over the years and how harmonization was reached in the various Standards. Finally, a proposal for future work is outlined.
