AS/NZS 3718:2005
Water supply - Tap ware
Specifies requirements for metallic taps, plastic taps, mixing taps, sensor taps, lever taps, time/flow taps, mixing taps mechanical (non-thermostatic), and tap sets in a range of nominal sizes from DN 6 to DN 50 generally for continuous operating temperatures not exceeding 80 degrees C. Products designed for other temperature ranges are included where tested to the appropriate temperature criteria. It incorporates the testing requirements for the determination of flow rates required by the Water Efficient Labelling and Standards Scheme (WELS). The Standard also specifies additional requirements for outlets that are an integral part of a tap or mixing tap and the requirements for tapset breaching piece assemblies.
