AS 1657-1992 Fixed platforms, walkways, stairways and ladders - Design, construction and installation
Standards Australia
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 —
(a) reducing the minimum wall thickness of steel piping which may be used;
(b) incorporating a minimum tensile yield stress requirement for aluminium alloys;
(c) deleting references to specific aluminium alloys and tempers;
(d) updating the dimensions of steel sections other than piping, to reflect current manufacturing practices; and
(e) provision of test methods to determine the integrity of guardrail systems, and the strength of the connection between guardrail posts and the supporting structure.
First published as AS CA10-1938.
This Standard sets out requirements for the design, construction, and installation of fixed platforms, walkways, stairways, and ladders which are intended to provide means of safe access to and safe working at places normally used by operating, inspection, maintenance, and servicing personnel.
The Standard does not apply to situations where special provision is made in appropriate building or other regulations, e.g. means of escape from fire. Requirements for portable ladders are not included in this Standard.
