To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments
5、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 Standards may also be withdrawn.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. Detailed information about joint Australian/New Zealand Standards can
6、be found by visiting the Standards Australia web site at .au or Standards New Zealand web site at www.standard.co.nz and looking up the relevant Standard in the on-line catalogue. Alternatively, both organizations publish an annual printed Catalogue with full details of all current Standards. For mo
7、re frequent listings or notifi cation of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options. For information about these services, users should contact their respective national Standards organization. We also welcome suggestions for
8、 improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities.

12、VERSITY OF SOUTH AUSTRALIA on 02 Apr 2008 AS/NZS 3679.1:19962 PREFACE This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee BD/23 on Structural Steel to supersede AS 3679.11990. This Standard incorporates Amendment Nos. 1 and 2 (May 2000). The changes required b
13、y the Amendments are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure, or part thereof affected. The objective of this Standard is to specify requirements for hot-rolled structural steel bars and sections for general structural and engineering appl
14、ications. This edition incorporates Amendment No. 1 and the following major changes: (a)Deletion of weather-resistant weldable grades. (b)Increase of copper content to 0.5%. (c)Modification of the chemical and mechanical properties for grade 300 on some sections. (d)Deletion of universal bearing pil
15、es. (e)Deletion of 760 and 690 universal beams. (f)Geometrical properties of steel sections are deleted. (g)Appendix B is updated. A statement expressed in mandatory terms in a note to a table is deemed to be a requirement of this Standard. The terms normative and informative have been used in this
16、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.
