5、UTH AUSTRALIA on 12 Dec 2006Review of S tand ards . To keep abreast of progress in industry, Joint Australi an/New Zealand St andards are subject to periodic review and are kept up to date by the issue of amendments or new edit ions as necessary. It is important therefore that S tandards users ensur

6、e that they are in possession of the latest edit ion, and any amendments thereto.Full detail s of all Joint S tandards and related publications will be found in the St andards Australia and St andards New Zealand Catalogue of Publi cations; this information is supplemented each month by the magazine

7、s The Australian St andard and S tandards New Zealand, which subscribing members receive, and which give details of new publicati ons, new editions and amendments, and of withdrawn St andards.Suggesti ons for improvements to Joint S tandards, addressed to the head office of either St andards Austral

8、ia or St andards New Zealand, are welcomed. Notification of any inaccuracy or ambiguity found in a Joint Australi an/New Zealand St andard should be made without delay in order that the matter may be investigated and appropriate acti on taken.This Standard was issued in draft form for comment as DR
