Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 817:1997. This European Standard acknowledges the field of application for mechanical mixing valves used in water supply systems with a pressure range of (0,05 to 1,0) MPa (0,5 bar to 10 bar).

EN 817:2008 (E) 7 Introduction In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this European Standard. This European Standard provides no information as to whether the product can be used without restriction in any of the Member States of the EU or EFTA. It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. This document identifies characteristics and technical requirements for mechanical mixing valves. SIST EN 817:2009
