This European standard specifies the field of application, the dimensional, the physico-chemical, the design, the hydraulic, the mechanical, and the acoustic characteristics of mechanical disconnector direct actuated Family G;Type A. This European standard is applicable to mechanical disconnectors direct actuated in nominal sizes DN 8 up to DN 250 included, intended to prevent the return of water having lost its original sanitary and drinking qualities (called "polluted water" in this document), into the potable water distribution system whenever the pressure of the latter is temporarily lower than in the polluted circuit. This standard covers the mechanical disconnectors direct 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 their characteristics, the marking and the presentation at delivery.
