This European standard specifies the: - field of application; - the dimensional, the physico-chemical, the design, the hydraulic, the mechanical and the acoustic characteristics of backflow preventer with different non-controllable pressure zones family C type A and of nominal sizes DN 6 to DN 50 inclusive and in nominal pressure PN 10. It is applicable to: - Family C, type A, class "a" for general use: devices of class "a" shall be capable of working: - at any pressure up to 1 Mpa (10 bar); - with any pressure variation up to 1 Mpa (10 bar); _ at a temperature limit of 65 °C and 90 °C for 1 h; - Family C, type A, class "b" for restricted temporary use: devices of class "b" shall be capable of working: - at any downstream pressure up to 300 kPa (3 bar); - with any downstream pressure variation up to 300 kPa (3 bar); The devices of class "b" to have restricted hydraulic and no acoustic requirements and are designated for water supply to systems with a temperature limit of 110 °C.
