Optionally co-design standards:
This document specifies:
a) field of application;
b) requirements for pipe interrupters with permanent atmospheric vent;
c) dimensional, the physico-chemical properties and the properties of general hydraulic, mechanical and
acoustic design of pipe interrupters with permanent atmospheric vent, DN 10 to DN 20;
d) test method and requirements for verifying these properties;
e) marking and presentation;
f) acoustics.
This document specifies the characteristics of pipe interrupters with permanent atmospheric vent, DN 10 to
DN 20 that are suitable for use in drinking water systems at pressures up to 1 MPa (10 bar) and temperatures
up to 65 °C and for 1 h 90 °C.
Backflow protection devices integrated in flushing valves are similar to DC and are not covered under this
document. The requirements are stated in EN 12541.
