AS/NZS 3718:2005


Water supply - Tap ware

Specifies requirements for metallic taps, plastic taps, mixing taps, sensor taps, lever taps, timed flow taps, mixing taps mechanical (non-thermostatic), and tapsets in a range of nominal sizes from DN 6 to DN 50, generally for continuous operating temperatures not exceeding 80 degrees Celsius. Products designed for other temperature ranges are included where tested to the appropriate temperature criteria.
