scope:

This European standard specifies requirements for low hydraulic resistance mechanical mixing valves suitable for use in low pressure water supply systems as described in informative Annex C. This European Standard specifies: - the dimensional, leaktightness, mechanical and hydraulic performance, mechanical endurance characteristics with which low pressure mechanical mixing valves shall comply; - the procedure for testing these characteristics. It is applicable: - to low pressure mechanical mixing valves, intended for use on sanitary appliances in washrooms (toilets, bathrooms etc.) and in kitchens; - to low pressure mechanical mixing valves used under the following pressure and temperature conditions given in table 1.
