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.
Annex A contains a template for the relevant cylinder design International Standards (i.e. ISO 9809-1,ISO 9809-2, and ISO 9809-3 for seamless steel and ISO 7866 for seamless aluminium alloy cylinders). It further contains information on how to implement the provisions into other cylinder design standards.
It is intendedthattheprovisionslaid outinthisTechnical Reportshouldbe followedbyISO/TC58/SC3working groups dealing with the design standards for seamless steel (ISO 9809-1, ISO 9809-2, and ISO 9809-3) and aluminium alloy gas cylinders (ISO 7866) at the next revision of these International Standards.
The tables in Annex A are based on the current “Defect Annexes” of ISO 9809-1, ISO 9809-2, and ISO 9809-3 for seamless steel cylinders and ISO 7866 for seamless aluminium alloy cylinders. Those imperfections applicable for the ISO 9809 series are contained in Tables A.1 and A.2, and those applicable for ISO 7866 are contained in Tables A.3 and A.4.
They are written in such a way that they can also be incorporated in other design standards as a normative annex.
The provisions of this Techincal Report should also serve as a basis for a future annex to each of the other relevant design standards (other than ISO 9809-1, ISO 9809-2, ISO 9809-3, and ISO 7866) for seamless cylinders and tubes.
If incorporated in other design standards the content ofthe columns “Type ofimperfection”,”Description”,and“Note” in Tables A.1, A.2, A.3, and A.4 (which were established by WG 34) should remain unchanged.
The tables should be reviewed by the other relevant ISO/TC 58/SC 3 working groups, in particular, the column “Decision at the time of inspections and follow-up actions” and the three imperfection levels.
Where necessary, these conditions can be adapted to reflect the conditions appropriate to their product.
If the individual working groups intend to adopt other typical manufacturing imperfections specific to their product, they can do so, provided the structure of the tables and the remaining provisions are followed.ISO TR 16115 pdf download.
