Description

The objective of this Standard is to provide manufacturers with requirements for tempering valves and end-of-line temperature-actuated devices that give reasonable protection to users against exposure to high or excessive fluctuations in mixed water temperatures caused by the following:

(a) Maintaining an outlet temperature within specified limits, including shut-off of the cold water supply.

(b) Closing the outlet when the mixed water temperature exceeds a specified maximum.

This Standard is Part 2 of a suite of Standards that covers valves for the control of hot water temperatures, as follows:

AS
4032       Water supply—Valves for the control of hot water supply temperatures

4032.1    Part 1: Thermostatic mixing valves—Materials, design and performance requirements

4032.2    Part 2: Tempering valves and end-of-line temperature-actuated devices (this Standard)

4032.3    Part 3: Requirements for field testing, maintenance or replacement ofthermostatic mixing valves, tempering valves and end-of-linetemperature control devices

Scope

This Standard specifies requirements for the design, construction, testing and performance of -

  • (a) tempering valves of nominal sizes not larger than DN 32; and
  • (b) end-of-line temperature-actuated devices of nominal size not larger than DN 25,

for use with heated water at -

  • (i) continuous operating temperature not exceeding 85°C;
  • (ii) temperature under emergency conditions, not exceeding 99°C; and
  • (iii) continuous working pressure not exceeding 1400 kPa.

Devices complying with this Standard are intended to prevent a continuous discharge of water from the outlet in excess of 50°C under steady-state conditions.

Transient discharges of water with a temperature in excess of this figure, which comply with the specified cumulative time/temperature factors, are acceptable.

Note: Tempering valves, when adjusted to an outlet temperature not exceeding 50°C, and end-of-line devices may be used for temperature-limiting for ablution purposes, to minimize the risk of scalding, other than for use in health care, aged care, child care, care for people with disabilities and any other at-risk situations. Thermostatic mixing valves complying with AS 4032.1, when adjusted to an outlet temperature not exceeding 45°C, are intended for use in health care, aged care, child care, care for people with disabilities and any other at-risk situations.
