ČSN EN 246

This document specifies:
- the dimensional, mechanical, hydraulic and acoustic characteristics with which sanitary tapware aerators (with and without flow regulation) should comply;
- the procedures for testing these characteristics.
This document is applicable to:
- Sanitary tapware aerators intended to be mounted on tapware used with sanitary appliances in toilets, bathrooms and kitchens (e.g. single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves);
- Sanitary tapware aerators used under the following pressure and temperature conditions (see Table 1).
Table 1 - Conditions for the use of aerators
Limits of use Recommended limits for correct operation
Dynamic Pressure 0,05 MPa <= P <= 0,5 MPa 0,1 MPa <= P <= 0,5 MPa
(0,5 bar <= P <= 5 bar) (1 bar <= P <= 5 bar)
Temperature <= 70 °C <= 65 °C
