PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee WS/14 on the National Plumbing and Drainage Code

This Standard is the result of a consensus among representatives on the Joint Committee

to produce it as an Australian Standard

This Standard sets out objectives for sanitary plumbing and drainage in its functional and performance requirements

Reference to AS/NZS 3500.2.2, National Plumbing and Drainage, Part 2.2: Sanitary plumbing and drainage — Acceptable solutions sets out a means of achieving minimum

deemed-to-satisfy requirements for the objectives and performance requirements of this Standard

It is recognized that the content of this part Standard would usually be the responsibility

of a regulatory body Nevertheless, owing to the reforms taking place in the industry at present, no national body has yet been identified to take up such responsibilities Therefore, for the purpose of this edition the document is published as part of the

AS 3500 series If in the future a national regulatory administration is identified, the Standard will be modified accordingly

The performance requirements of this Standard have been published excluding a

‘durability’ clause This course of action was found necessary owing to a division existing within the committee members responsible for the document It is possible that in the future durability requirements could become part of this document by means of an amendment or a full revision of the Standard
