19、quality of water intended for human consumption, caused by the product covered by this standard: This standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA. It should be noted that, while awaiting the adoption of veri
20、fiable European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force.

21、 1 Scope This European Standard specifies: the dimensional, leaktightness, mechanical, hydraulic and acoustic characteristics with which extractable outlets with or without spray mode selector function need to comply; the procedures for testing these characteristics. It applies to extractable outlet
22、s made from any material which is intended for equipping and supplementing sanitary tapware for sinks and wash-basins used for culinary or ablutionary purposes. Such extractable outlets shall only be connected downstream of the obturator of the tapware. Extractable outlets with total closing device
23、fitted after the obturator of the tapware are not covered by this standard. Such products will be tested in accordance with EN 200, EN 817, EN 1111, EN 1286 or EN 1287 (see 1, 2, 3, 5 and 6). The conditions of use and classification are specified in Table 1. BS EN 16145:2012EN 16145:2012 (E) 6 Table
