Procedure for Developing Technical Specifications

PREFACE

Australian Technical Specification ATS 5200.999-2005, Technical specification for plumbing and drainage products, Part 999: Developing technical specifications was prepared by the Joint

Standards Australia/Standards New Zealand Committee WS-031, Technical Procedures for

Plumbing and Drainage Products Certification. It was approved on behalf of the Council of

Standards Australia on 21 February 2005 and supersedes ATS 5200.000—2004.

The objective of this Technical Specification is to provide writers of technical specifications for plumbing and drainage products with guidance and specific requirements for writing a

WaterMark Technical Specification. The electronic template for WaterMark Technical

Specification can be found on the ABCB website ( www.abcb.gov.au

).

The word ‘VOID’ set against a clause indicates that the clause is not used in this Technical

Specification. The inclusion of this word allows a common use clause numbering system for the

WaterMark Technical Specifications.

The term ‘normative’ has been used in this Technical Specification to define the application of the appendices to which they apply. A ‘normative’ appendix is an integral part of a Technical

Specification.

The new WaterMark scheme facilitates the certification and authorisation of plumbing and drainage products in accordance with Part G1, of the Plumbing Code of Australia. The

WaterMark Schedule of Specifications and List of Exempt Products are dynamic lists and change on a regular basis. Based on this function, these lists have been removed from the

WaterMark Certification Scheme document known as Technical Specification for Plumbing and

Drainage Products and are now located on the ABCB website (www.abcb.gov.au). These lists will be version controlled with appropriate historic references.
