1 Scope
This European Standard specifies:
-
— the dimensional, mechanical, hydraulic and acoustic characteristics with which flow rate regulators should comply;
-
— the procedures for testing these characteristics.
This European Standard is applicable to:
-
—
flow rate regulators intended to be mounted on tapware used with sanitary appliances in toilets, washrooms
and kitchens (single taps, combination tap assemblies, mechanical mixing valves, thermostatic
mixing valves);
-
—
flow rate regulators used under the following pressure and temperature conditions:

Conditions for the use of flow rate regulators
|
Limits of use |
Recommended limits for correct operation |
| Dynamic Pressure |
0,05 MPa ≤ P ≤ 0,5 MPa (0,5 bar ≤ P ≤ 5 bar)
|
0,1 MPa ≤ P ≤ 0,5 MPa (1 bar ≤ P ≤ 5 bar)
|
| Temperature |
≤ 70 °C
|
≤ 65 °C
