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.
