[Superseded]Drinking water treatment units — Plumbing requirements
Specifies requirements for the construction, installation and testing of drinking water treatment units and equipment, or appliances, or both, designed for domestic type applications under Australian and New Zealand climatic conditions, but does not preclude their use for commercial or industrial applications. These appliances are designed to be used for the reduction of specific groups of contaminants from a drinking water supply (public or private), such contaminants being specified by the manufacturer or reseller of the appliances. The Standard establishes minimum requirements for point of use (POU), point of entry (POE) and stand-alone appliances.
