To maintain their currency, all Standards are periodically r
4、eviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased.
5、Detailed information about Standards can be found by visiting the Standards Australia web site at .au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Australian Stan

10、mittee MT-001, Iron and Steel. After consultation with stakeholders in both countries, Standards Australia and Standards 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 specify requirements an
11、d tests for carbon steel spring wire of round cross-section for the manufacture of mechanical springs. Four types, or conditions, of spring wire are covered. During revision of this Standard cognisance was taken of the three-part International Standard ISO 8458, Steel wire for mechanical springs. Th
12、e Committee decided against its adoption as an Australian Standard because it does not cover the full range of mechanical spring wires used by Australian industry, and it imposes unacceptable restrictions on wire manufacturing practice. Notable changes that have been introduced in the revised Standa
13、rd relate to wire diameter tolerances, which have been rationalized, and to coil presentation and cast, which are now more clearly specified. The Standard has been expanded in respect of optional drawn metallic coatings and now includes zinc/aluminium-alloy coatings. The coating class, previously un
14、specified, for both zinc and zinc/aluminium-alloy coatings has been set at W02. The term informative has been used in this Standard to define the application of the appendix to which is applies. An informative appendix is only for information and guidance. Accessed by UNIVERSITY OF SOUTH AUSTRALIA o
