Sanitary tapware - General specifications for aerators EN 246:2021

Publication date:   Mar 23, 2022

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).
[Table 1: Conditions for the use of aerators]
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.
NOTE 4 Aerator swivels are to be tested in combination with a specific aerator only and are therefore considered to be sanitary tapware accessories. (Testing of the stand-alone swivels is therefore not covered by the scope of this document. Where swivels are used they are considered to be part of the tapware constructions, e.g. for bidet taps).
