    Abstract - (Show below) - (Hide below)

    Specifies requirements for the design, construction, testing and performance of tempering valves of nominal sizes not larger than DN 32 and end-of-line temperature-actuated devices of nominal size DN 15, for use with hot water at a supply temperature not exceeding 99 degrees Celsius, and hot and cold water with continuous working pressures not exceeding 1400 kPa.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for the design, construction, testing and performanceof(a) tempering valves of nominal sizes not larger than DN 32; and(b) end-of-line temperature-actuated devices of nominal size DN 15, for use with hot water at(i) continuous operating temperature not exceeding 85C;(ii) temperature under emergency conditions, not exceeding 99C; and(iii) continuous working pressure not exceeding 1400 kPa.The major requirement of the testing procedures is that the device under test does not permit the continuous discharge of water from the outlet in excess of 50C.Discharges of water with a temperature in excess of this figure, which comply with the specified cumulative time/temperature factors, are acceptable.
