AS 3718:2021 Water supply一Tap ware

AS 3718:2021 Water supply一Tap ware. AS 3718 specifies requirements for metallic taps, plastic taps, mixing taps, sensor taps, lever taps, timed flow taps, mixing taps mechanical (non-thermostatic), and tapsets in nominal sizes ranging from DN 6 to DN 50 that are designed to be used generally for continuous operating temperatures not exceeding 80 °C and maximum dynamic operating pressure 500 kPa. This Standard does not prevent the use of products designed for other temperature ranges provided they meet the performance requirements specified herein. The Standard also specifies requirements for outlets of a tap or mixing tap and for tapset breaching piece assemblies. Means for demonstrating conformance to this Standard are given in Appendix A. NOTE Where the static hot and cold water supply systems pressures are below 35 kPa, then water-efficient tap ware may not need to be fitted. 1.2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
