This European Standard specifies requirements and gives recommendations for the installation of potable water installations within buildings and for pipework outside buildings but within the premises in accordance with EN 806-1.This European Standard is applicable to new installations, alterations and repairs.
This European Standard specifies:-- the dimensional, leaktightness, pressure resistance, hydraulic performance, mechanical strength, endurance and acoustic characteristics with which mechanical mixing valves need to comply;-- test methods to verify the characteristics.The tests described in this European Standard are type tests (laboratory tests) and not quality control tests carriedout during manufacture.This European Standard applies to PN 10 mechanical mixing valves for use with sanitary appliances installed inrooms used for bodily hygiene (cloakrooms, bathrooms, etc.) and in kitchens, i.e. for use with baths, wash basins,bidets, showers and sinks.The conditions of use and classifications are given in O.
This part of this European Standard specifies the essential requirements for equipment and protective devices for a water-tube boiler plant as defined in EN 12952-1,to ensure the boiler operates safely within the allowable limits (pressure,temperature, etc.).

This document specifies:a) field of application;b) requirements for automatic diverters;c) dimensional and the physico-chemical properties and the properties of general hydraulic, mechanical andacoustic design of automatic diverters;d) test method and requirements for verifying these properties. For sanitary tapware (see Clause 2) with integrateddevices, the automatic diverter is only considered to be a backflow protection device if it haspassed the requirements of this document and additionally those of the applicable product standard forthe draw off tap or mixing valve;e) marking and presentation;f) acoustics.This document specifies the characteristics of automatic diverters suitable for use in drinking water systems atpressures up to 1 MPa (10 bar) and temperatures up to 65 °C and for 1 h at 90 °C. They are intended only forinstallation with no downstream closing device.This document is applicable to the product type indicated as follows:i) integrated in spout (outlet);ii) integrated in the mixing body;iii) non-integrated (part of a set) above the maximum water level.This document is not applicable to the product type non-integrated below the maximum water level.
