11、 Standards Australia/Standards New Zealand Committee ME-002, Gas Cylinders to supersede AS 2473.32004, Valves for compressed gas cylindersOutlet connections for medical gases (including pin-indexed yoke connections). After consultation with stakeholders in both countries, Standards Australia and Sta
12、ndards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard. The objective of this Standard is to provide manufacturers of medical equipment, the medical gases industry and medical facilities with specifications for outlet connections
13、for gas cylinders containing medical gases. Dimensions for pin-indexed yoke connection in earlier versions of this Standard up to 1996, when its designation was changed from AS 2472 to AS 2473.3, were taken from the metric range of BS 1319:1976, Specification for medical gas cylinders, valves and yo
14、ke connections (later replaced by EN 850), which in turn aligned closely with ISO 407, Small medical gas cylindersPin-index yoke-type valve connections. Both Standards were derived from earlier versions of CGA V-1:2002, Compressed gas cylinder valve outlet and inlet connections. However, all these S
15、tandards differ in minor but noticeable ways in the dimensions of the connections. Although connections made to each Standard are believed to be functionally interchangeable, users should be aware of the existence of differences. This Standard maintains the general structure and much of the content
16、of ISO 407, however, some changes have been made and considerable material has been added to accommodate existing Australian practice. However, cylinder valves complying with ISO 407 are functionally interchangeable with yoke connections made to this Standard and vice-versa. The figure numbers for t
17、he yoke outlet connections from the 2004 revision of this Standard are those in ISO 407 and users should be aware that they differ from those in AS 2472 1996 and earlier revisions. Appendix A summarizes the correspondence between clauses in this Standard and ISO 407. In this revision the outlet conn
18、ections for all sizes of oxygen cylinders are specified as the pin-indexed yoke connection from Table 1. The formerly specified threaded outlet for cylinders with a water capacity exceeding 5 kg has been removed, and cylinders currently fitted with valves with that connection will be converted to pi
19、n-indexed yoke connections over a period of time. Hence from this revision all outlet connections for medical gas cylinders are specified only in this Standard. A revision of ISO 407 in 2004 corrected some errors. To maintain alignment as well as to correct other errors in AS 24732004, Figures 1(a),
20、 2, 3 and 4, Table 2 and Table 3 (connections A-F, B-F, D-F, E-F, A-G, E-G, E-H, B-J and E-J) have been modified in detail in this edition. The titles of this Standard and ISO 407 both refer to outlet connections only, yet a number of associated requirements pertaining to other features of the valve
21、 itself are specified in both documents. However, AS 2473.12006 is now referred to for the general valve requirements. It is important to note that users of existing equipment with connection to AS 24721996, Figure 14 will be required to change to the corresponding applicable connection from this St
