Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto.
Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine 'The Australian Standard', which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards.
Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

This Standard was issued in draft form for comment as DR 90065.

PREFACE

This Standard was prepared by the Standards Australia Committee on Platforms, Gangways, Stairways and Ladders, to supersede AS 1657-1985.

Changes to the Standard include —

1. reducing the minimum wall thickness of steel piping which may be used;
2. incorporating a minimum tensile yield stress requirement for aluminium alloys;
3. deleting references to specific aluminium alloys and tempers;
4. updating the dimensions of steel sections other than piping, to reflect current manufacturing practices; and
5. provision of test methods to determine the integrity of guardrail systems, and the strength of the connection between guardrail posts and the supporting structure.
