AS 4032.4:2014 pdf free.Water supply – Valves for the control of heated water supply temperatures
An operating safety feature wherein, if a thermostatic mixing tap is subjected to the shut-off of the cold or heated water supply to it, the risk of scalding or cold shock to the user or person(s) exposed to the mixed water is minimized.
A tap into which hot and cold water entering through separate ports are mixed in a chamber and then delivered through a single common outlet, the temperature of the mixed water being automatically controlled at a user-adjustable temperature that is suitable for direct contact with the skin and which gives the user the ability to shut-off the outlet flow.
NOTES:
1 A product with multiple outlets selected by an integral diverter valve is considered to have a single outlet.
2 The product may also deliver cold water without mixing.
A device that may be used to control the rate of discharge of the mixed water. It is an integral part of an end-of-line valve or connected to the outlet for an in-line valve, and which may incorporate a temperature control valve.
Products complying with this Standard shall be marked with the following information:
(a) Manufacturer’ s name, trademark or symbol.
(b) Name or model number of the product.
(c) Identification for traceability in the form of either –
(i) batch identification; or
(ii) individual serial number.
(d) Certification mark.
(e) Controls used to vary the temperature of the mixed water shall be permanently marked, to make the effect of movement understood by the user.
(f) The letter‘H’, the word‘HOT’or a red indicator for the heated water inlet. The letter “C’, the word‘COLD’ or a blue indicator for the cold water inlet.
(g) The number of this Standard (i.e. AS 4032.4).
(h) The maximum working pressure.
(i) For electronic taps, the following shall be included:
(i)Electrical supply information- operating voltage and the rating in amperes or loading in W or VA. Any limitation to the operation of the product shall also be marked (a.c., d.c., frequency, etc.).
(ii) A warning that the valve requires connection to electrical power and that it will not operate without power.AS 4032.4 pdf free download.
