3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 1717:2000, EN 806-1:2000 and the

following apply.
pipe interrupter with atmospheric vent and moving element

pipe interrupter with elastic membrane, fitted with air inlet port(s) which is (are) closed, when water flows

through it above atmospheric pressure, but which opens (open) to admit air if there is a subatmospheric pres-

sure at the water inlet or when the flow stops, and close to be watertight when the flow of water is resumed at

normal pressure. It ensures protection against back siphonage only by draining to the atmosphere, but not

against back pressure. Direction of water flow is vertically downwards.

For the purpose of this document “pipe interrupter with atmospheric vent and moving element DB” is hereafter

referred to as "device(s)"
4 Nominal size

The nominal size of the device shall correspond to the denomination of the thread according to Table 1,

EN ISO 228-1 or ISO 7-1.
Table 1 — Nominal size vs union end thread size

5 Designation
The devices are designated by:
a) name;
b) reference to this document (EN 14452);
c) family, type;
d) nominal size (DN);
e) body material;
f) acoustic group.
