Gives requirements for welded steel cylinders from 0.1 kg to 35 kg water capacity, increasing the upper limit from 11 kg in the previous edition. It introduces the use of stainless steel for these cylinders in addition to the previously used carbon steel. It also introduces the use of quality control procedures for manufacturers at the point of entry into Australia.

This Standard specifies requirements for welded carbon and stainless steel cylinders with no longitudinal joint and one circumferential joint, of water capacity not less than 0.1 kg nor more than 35 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. Stainless steel cylinders shall be constructed in accordance with 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 2470, 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.
