WaterMark Product Specifications are referenced in the Schedule of products. The schedule enables the evaluation and certification of products under the Scheme, in accordance with the Manual for the WaterMark Certification Scheme.

WaterMark Technical Specifications (WMTS) are published by the Australian Building Codes Board (ABCB), as part of our role in managing and administering the scheme. Other product specifications or standards which are referenced in the Schedule of Products are developed and published by third parties. These product specifications include but are not limited to Australian (AS) or Australian/New Zealand (AS/NZS) standards, European Standards (EN), International Electrotechnical Commission (IEC) Standards and International Organisation for Standardisation (ISO) Standards.

A WMTS or third party published specification may be developed, where no approved specification can be used for evaluating a plumbing or drainage product. For more information about developing a WMTS or third party published product specification, refer to Appendix 4 of the Manual for the WaterMark Certification Scheme.

All current WMTS are listed below.


All new or amended product specifications must be released for public comment prior to acceptance for reference in the Schedule of Products. The Australian Building Codes Board's Consultation Hub provides links to all documents currently open for comment.
