6、uthority, Tas.Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possessio
7、n of the latest edition, and any amendments thereto.Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine The Australian Standard, which subscribing members rec
8、eive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards.Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Stand

12、ompressed gases Welded 0.1 kg to 11 kg. It is the result of a consensus amongst representatives of the Joint Committee to provide it as an Australian Standard.This Standard is one of a suite of four Standards for welded and brazed cylinders for compressed gases, the other Standards being as follows:
13、AS2468Steel cylinders for compressed gases Brazed 0.1 kg to 11 kg.2470Steel cylinders for compressed gases Welded three-piece construction with longitudinal joint 11 kg to 150 kg3577Steel cylinders for compressed gases Welded 150 kg to 500 kg.This Standard provides for gas cylinders produced in larg
14、e quantities. Users of this Standard should note that a competent person or body will require either quality control procedures to be employed at the point of manufacture in Australia, or, for cylinders manufactured overseas, sampling and testing at the point of entry into Australia. It should also
15、be noted that before a gas cylinder can be first filled in Australia it must be stamped with a Standards Australia Certificated Gas Cylinder Test Station registered mark in accordance with the relevant Standard in the AS 2030 series.The construction now allows two piece welded cylinders to be made w
16、ith capacities up to35 kg water capacity.The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance. Co
