This Standard forms a basis for the rating and labelling of a range of products under the mandatory Water Efficiency Labelling and Standards (WELS) scheme, as required by the Australian Water Efficiency Labelling and Standards Act 2005 (Cth) (the WELS Act) and, in New Zealand, the Consumer Information Standards (Water Efficiency) Regulations. This Standard has been updated to reflect changes to the WELS Act and to remove ambiguities and superseded and conflicting requirements.

The objectives of the WELS Scheme are to encourage the development and marketing of water efficient products and to enable consumers to clearly identify and purchase water efficient products.

All products specified under the WELS Act have to be registered, rated and labelled according to the requirements of this Standard. All registrations have to be made through the WELS Regulator. The specified products are washing machines, the dryer function of combination washers/dryers (where they use water to dry a load), dishwashers, flow controllers, lavatory equipment, showers, tap equipment and urinal equipment. In Australia, lavatory equipment, showers, tap equipment and urinal equipment are required to comply with minimum water efficiency requirements set out in the National Construction Code, Volume Three — Plumbing Code of Australia (NCC). Dishwashers and washing machines are also required to comply with minimum water efficiency requirements set out in this Standard. In New Zealand the requirements of this document apply.
