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 |
Flow rate regulators can only be connected downstream of the obturator of the tap.
