This Technical Report specifies the procedure on how to evaluate and treat the most commonly found manufacturing imperfections on seamless steel and aluminium alloy gas cylinders at visual inspection at the stage of product acceptance.
AnnexA contains a template for the relevant cylinder design International Standards (i.e. ISO9809-1, ISO9809-2, and ISO9809-3 for seamless steel and ISO7866 for seamless aluminium alloy cylinders). It further contains information on how to implement the provisions into other cylinder design standards.
