scope:

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).

Note 1: Sanitary tapware aerators can only be connected downstream of the obturator of the sanitary tapware product.

Note 2: For the purposes of brevity, sanitary tapware aerators will be detailed only as aerators in the rest of this document.

Note 3: The tests described in this document are type tests (laboratory tests) and not quality control tests carried out during manufacture.
