Abstract	The objective of this study was to establish a sound technical basis for developing quantitative, "maximum allowable flaw sizes" and for setting acceptance/rejection limits for high pressure steel and aluminum cylinders at the time of retesting that are based on the performance of the cylinders. Seamless steel and aluminum cylinders that are used to transport high pressure gases are required to meet safety regulations promulgated by the U.S. Department of Transportation and other national authorities. These safety regulations cover the design, materials, manufacturing, testing and retesting of the cylinders. As part of these safety regulations the cylinders are required to be periodically retested during their lifetime. In this study, the performance of selected cylinders was evaluated based on the principle of structural integrity analysis. The study was limited to an assessment of flaws in steel cylinders, as comparable data from aluminum cylinders is not currently available.
