scope:

This European Standard specifies general construction, performance and material requirements for high pressure supplied thermostatic mixing valves and includes test methods for the verification of mixed water temperature performance at the Point of Use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, the mixed water temperature shall be set at a suitable bathing temperature (body temperature - 38 °C) as children are at risk to scalding at lower temperatures than adults. This does no obviate the need for supervision of young children during bathing. This standard allows thermostatic mixing valves to supply a single outlet or a small number of outlets in a "domestic" application (e.g. one valve, controlling a shower, bath, basin, bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use).
