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 ination 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which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards.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.

AS 417619942 PREFACE This Standard was prepared by the Joint Australia/New Zealand Standards Committee PL/6, on Polyethylene Pipe, under the direction of the Building Standards Policy Board. The following documents were considered during the preparation of this Standard ASTM F128190CrosslinkedPolyethylene/Aluminium/CrosslinkedPolyethylenePEX-AL- PEX pressure pipe F128290Polyethylene/Aluminium/PolyethylenePE-AL-PE composite pressure pipe The Committee decided to use the terminology macro-composite to better describe the pipe structure. The term ‘macro’ reflects the three separate component layers working together in the pipe wall as opposed to the more common fibre-reinforced composite pipe structures. The terms ‘normative’ and ‘inative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘inative’ appendixis only for ination and guidance. CopyrightSTANDARDS AUSTRALIA Users of Standards are reminded that copyright subsists in all Standards Australia publications and software.
