DESCRIPTION

BS EN 13433:2021 - TC


This standard BS EN 13433:2021 - TC Tracked Changes. Devices to prevent pollution by backflow of potable water. Mechanical disconnector, direct actuated. Family G, type A is classified in these ICS categories:
  • 13.060.20 Drinking water
  • 23.060.50 Check valves
This document specifies the dimensional, physical-chemical, design, hydraulic, mechanical and acoustic characteristics of mechanical disconnectors, direct actuated Family G, Type A. This document is applicable to mechanical disconnectors 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 document), into the potable water distribution system whenever the pressure of the latter is temporarily lower than in the polluted circuit. This document covers the mechanical disconnectors of PN 10 that are capable of working without modification or adjustment: — at any pressure up to 1,0 MPa (10 bar); — with any pressure variation up to 1,0 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.
