This European Standard specifies, the dimensional, the physico-chemical, the design, the hydraulic, the mechanical and the acoustic characteristics of mechanical disconnector, hydraulic actuated Family G, type B. This European Standard is applicable to mechanical disconnectors hydraulic actuated in nominal sizes DN 8 up to DN 250, intended to prevent the return of water having lost its original sanitary and drinking qualities (called "polluted water" in this European Standard), into the potable water distribution system whenever the pressure of the latter is temporarily lower than in the polluted circuit. This European Standard covers the mechanical disconnectors hydraulic actuated of PN 10 that are capable of working without modification or adjustment: - at any pressure up to 1 MPa (10 bar); - with any pressure variation up to 1 MPa (10 bar); - in permanent duty at a limit temperature of 65 °C and 90 °C for 1 h maximum. It specifies also the test methods and requirements for verifying these characteristics, the marking and the presentation at delivery.
