AS 4023.3 specifies the minimum requirements for field-testing, maintenance and replacement of thermostatic mixing valves, tempering valves, thermostatically controlled taps and end-of-line temperature-actuated devices

Preface

This Standard was prepared by the Australian members of the foint Standards Australia/Standards New Zealand Committee WS-026, Valves primarily for use in Warm and Hot Water Systems, to supersede AS 4032.3—2004, Water supply — Valves for the control of heated water supply temperatures, Part 3: Requirements for fied-testing, maintenance or replacement of thermostatic mixing valves, tempering valves and end-of ine temperature control devices

After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this document as an Australian Standard rather than an Australian/New Zealand Standard.

The objective of this document is to provide network utility operators and service personnel with the requirements for field-testing and maintenance of the devices specified in AS 4032.1, AS 4032.2 and AS 4032.4, for the frequency of maintenance and for the frequency of replacement of temperature operating components.

This document forms part of the AS 4032 series that covers valves for the control of hot water. temperatures. A list of all parts in this series can be found in the Standards Australia online catalogue. The major change in this edition is the inclusion of thermostatically controlled taps.

The terms “normative” and “informative” are used in Standards to define the application of the appendices to which they apply. A “normative” appendix is an integral part of a Standard, whereas an informative” appendix is only for information and guidance.
