AS 4032.3:2022 Water supply - Valves for the control of heated water supply temperatures, Part 3: Requirements for field-testing, maintenance or replacement of valves, taps and devices
Standards Australia
Supersedes: AS 4032.3-2004 Water supply - Valves for the control of heated water supply temperatures, Part 3: Requirements for field-testing, maintenance or replacement of valves, taps and devices
Draft Designation: DR AS 4032.3:2021The 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.
Originated as AS 4032.3-2004. Second edition 2022.
This document 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.
