To maintain their currency, all S
4、tandards are periodically reviewed, 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 Standards may also be withdrawn.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 t
5、he Standard was purchased. Detailed information about joint Australian/New Zealand Standards can be found by visiting the Standards Web Shop at .au or Standards New Zealand web site at www.standards.co.nz and looking up the relevant Standard in the on-line catalogue. Alternatively, both organization
6、s publish an annual printed Catalogue with full details of all current Standards. For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options.

11、ACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee, Welding Consumables, to supersede AS 1167.11993, Welding and brazing Filler metals, Part 1: Filler metal for brazing and braze welding. The objective of this Standard is to specify requirements for brazi
12、ng filler metal. The main changes in this edition have been driven by the increasing international concern at the risks of cadmium exposure and strategies at the global and Australian levels, and were aimed at cadmium minimization. Hence, the deletion of nine alloys containing cadmium (A4 to A7, A9
13、to A12 and A17) and the addition of six cadmium free alloys (A18 to A23) in Table 1. Other significant technical changes included the following: (a) Deletion of alloys with very little usage (A1, A3, A13, A14 and B5). (b) Reduction of cadmium impurity levels, in Tables 1 and 2, from 0.05 to 0.01%. (
14、c) Updating of melting ranges to show true liquidus values, and addition of Indicative Brazing Temperature Ranges in Table 2. (d) Deletion of alloy R4343 from Table 4, and updating Beryllium content from 0.0008% to 0.0003% to align with ISO Standards. In addition, Appendix A has been fully revised t
15、o update references to current equivalent EN, AWS and ISO Standards. Mechanical properties of brazed joints are not covered in this Standard but will generally be found in the relevant application Standards. The term informative has been used in this Standard to define the application of the appendi
16、x to which it applies. An informative appendix is only for information and guidance.
