Specifies requirements for the design, construction and performance of vacuum relief valves, thermosyphon arrestor valves, tempering valves, end-of-line temperature-actuated devices and isolating valves primarily for use in warm and hot water systems.

This Standard sets out requirements for the design, construction, testing and performance of the following types of water valves and devices:(a) Vacuum relief valves.(b) Thermosiphon arrestor valves.(c) Tempering valves.(d) Inlet pressure control valves.(e) End-of-line temperature-actuated devices.(f) Isolating valves.The valves and devices specified in this Standard are primarily intended for use in warm and hot water systems which are required to operate at-(i) continuous operating temperature not exceeding 85C;(ii) temperatures under emergency conditions, not exceeding 99C; and(iii) continuous working pressure not exceeding 1400 kPa.NOTE: For valves used with water heaters which are intended to operate at temperatures above 99C (e.g. hot water boilers), see AS 1271.
