Sanitary tapware. General specifications for flow rate regulators. | Status: Superseded, Withdrawn

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:

Table 1 — 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.
