Draft Designation: DR 06698Reconfirmed by: AS 2473.3-2007 REC:2017 Valves for compressed gas cylinders, Part 3: Outlet connections for medical gases (including pin-indexed yoke connections)
Changes to the 2000 edition include the following:
(a) Continued recognition of the trend to self-regulation and the need for clear guidance to industry.
(b) Updated information for New Zealand regulatory matters, seismic, wind and snow loading.
(c) An informative Appendix I on the use of equivalents when referring to various internationally available pressure equipment standards.
(d) Revision to Appendix A where ‘LP Gas fuel vessels for automotive use’ are now specifically mentioned as being covered by this Standard and where clarifications have been added for some equipment not covered by this Standard (regarding gas cylinders, miniature boilers and pressurized machines).
(e) Removal of the process for requesting opinions, interpretations or rulings. Readers will now need to make contact with Standards Australia as per information provided inside the front cover of this Standard.
(f) ‘Safety requirements’ changed from informative to normative.
(g) Updated Table 2.1, Standards for pressure equipment used in Australia and New Zealand.
(h) Detailed comparison between various equipment Standards available globally.
(i) Replacement of Appendix G, ‘Organization of Australian, New Zealand and Other Pressure Equipment Standards’ with a new Appendix ‘Australian Pressure Equipment Practice’.
This edition retains the role of the Standard as a major reference document and also to provide common requirements for pressure equipment that promote safety and uniformity throughout Australia and New Zealand.
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.
Statements expressed in mandatory terms in notes to tables and figures are requirements of this Standard.
Specifies outlet connections for gas cylinders containing medical gases, and specifies certain related design and manufacturing features of the valve. Reconfirmed: 2017-07-07 Originated as AS CB4 Supplement 1-1955. Previous edition AS 2473.3-2004. Second edition 2007.
This Standard is a ‘parent’ document for use by the pressure equipment industry in Australia and New Zealand. It covers the design, materials, manufacture, examination, testing, installation, conformity assessment, commissioning, operation, inspection, maintenance, repair, alteration and disposal of pressure equipment (boilers, pressure vessels and pressure piping), but excluding gas cylinders and other equipment as set out in Appendix A.
This Standard specifies detailed requirements for various pressure equipment by direct reference to a range of Australian, New Zealand and other Standards.
NOTES:
1: Appendix F provides a comparison of pressure equipment Standards.
2: Appendix G provides guidance on Australian pressure equipment practice.
