Introduces requirements for stainless steel in addition to the previously specified carbon steel for the manufacture of these compressed gas cylinders. It also includes the use of quality control procedures for manufacturers in Australia or checks on its implementation by overseas manufacturers at the point of entry into Australia.

This Standard specifies requirements for welded carbon and stainless steel cylinders with one longitudinal and two circumferential joints, of water capacity not less than 11 kg nor more than 150 kg, which have test pressures from 1750 kPa to 7000 kPa, and are intended for the storage and transport of compressed gases in accordance with AS 2030.1. Requirements for stainless steel cylinders are set out in Appendix A.NOTES:1 A gas cylinder manufactured by welding but which includes any brazing of, or on, the pressure-retaining portions is, for the purpose of this Standard, considered to be a brazed gas cylinder.2 Other Australian Standards for brazed and welded gas cylinders are AS 2468, AS 2469 and AS 3577.3 Appendix B lists the suggested minimum information that should be supplied by the purchaser when ordering gas cylinders to this Standard.
