101.1
This Standard specifies the requirements for control valves used in conjunction with hot water supply systems suitable for static supply pressures up to 2000 kPa (204 mH20) and working pressures up to 600 kPa (61 mH20) with temperatures not normally exceeding 85 °C. The methods of test detailed herein determine the ability of the valves to perform within specified limits of water pressure and temperature.
NOTE-
(1) For valves used with water heaters which are intended to operate at temperatures above 99 °C e.g. hot water boilers, see AS 1271.
(2) Refer to NZS 4603 and NZS 4607 for the application or installation of these valves in hot water systems.
