12、oint Standards Australia/Standards New Zealand Committee ME-002, Gas Cylinders to supersede part of AS 24731996, Valves for compressed gas cylinders (threaded outlet). After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standa
13、rd as an Australian, rather than an Australian/New Zealand Standard. This Standard results from a decision to expand AS 24731996 into a suite of Standards for valves for compressed gas cylinders based as much as possible on ISO Standards. This edition of AS 2473 comprises three parts as follows: Par
14、t 1: Specifications, type testing, and manufacturing tests and inspections (this Standard). Part 2: Outlet connections (threaded and stem (inlet) threads. Part 3: Outlet connections for medical gases (including pin-indexed yoke connections). Part 3 was formerly designated as AS 2472 and is largely b
15、ased on ISO 407. Further parts may be prepared in the future. This Standard was based on the following principles: (a) To align as closely as possible with ISO 10297, Transportable gas cylinders Cylinder valvesSpecification and type testing and ISO 14246, Transportable gas cylindersGas cylinder valv

18、sed gases, Part 1: Cylinders for compressed gases other than acetylene. (b) To provide a single Standard to cover the design and type testing of valves as well as their manufacturing tests and inspections, basing it as much as possible on the current versions and planned revisions of ISO 10297 and I
19、SO 14246. (c) To adopt the structure of ISO 10297:2006, making the minimum necessary changes to its Section 4, Valve design requirements, to resolve some inconsistencies and relax considerably its Section 6, Type testing methods to make it performance-oriented instead of rigidly prescriptive. In fol
20、lowing closely the structure and content of ISO 10297 (see Sections 2 and 4 of this Part) and ISO 14246 (see Section 3 of this Part), this Standard expands greatly the requirements for the specification and testing of cylinder valves in AS 24731996 whilst retaining its core concepts. This Standard f
21、ollows ISO 10297 with the following departures and changes: (i) Definitions of test pressures have been clarified and expanded to make them consistent with AS 2030.1. (ii) Requirements for manufacturing tests and inspections have been incorporated into the text, as they are in AS 24731996. (iii) Rel
22、ationship with ISO 11117, Gas cylindersValve protection caps and valve guards for industrial and medical gas cylindersDesign construction and tests has been clarified.

23、S 2030.1 and AS 2473.2 have been substituted for or expanded on those in ISO 10297. (v) Resistance to mechanical impact has been brought closer to the new approach in ISO 10297 but following and maintaining the experience gained with AS 2473 1996. (vi) Requirements for pressure relief devices accord
24、ing to AS 2030.1 and AS 2613, were introduced. It should be noted that AS 2473.1 modifies some requirements in AS 24731996 as indicated above, but AS 24731996 can only be withdrawn when AS 2473.2 is issued. Also it should be noted that, as with Australian Standards, ISO Standards are under continuou
