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).
