Description

This Standard specifies requirements for the design, construction, testing performance and means of compliance for thermostatic mixing taps—

• a) for use with heated water at a supply temperature not exceeding 90°C; 
• b) for use with hot and cold water with working pressures not exceeding 1400 kPa; and
• c) of nominal sizes not larger than DN 20.

When used for ablutionary purposes, thermostatic mixing taps complying with this Standard provide the user with reasonable protection against scalding or excessive temperature fluctuations due to variations of pressures and temperatures of the hot and cold water supplies, including thermal shut-off.

Scope

NOTES: 

1. Diagrams in this Standard are typical.
2. This Standard includes a method for assessing the flow performance of a thermostatic mixing tap but at the time of its publication, the Standard is not referenced in AS/NZS 6400.
