EN 16146:2012 (E) 4 Introduction In respect of potential adverse effects on the 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 verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force.

EN 16146:2012 (E) 5 1 Scope This European Standard applies to hoses for extractable outlets of any material intended for equipping sanitary tapware for sinks and basins. Such hoses will only be connected downstream of the obturator of the tapware. The tapware will comply with EN 200, EN 817, EN 1111, EN 1286 or EN 1287 (see [1], [2], [3], [5] and [6]). Hoses intended to connect sanitary tapware to the water supplies are not covered by this standard. This European Standard specifies:  the dimensional, mechanical and hydraulic characteristics with which the hose for extractable outlets shall comply;  the procedures for testing these characteristics. Details of pressures and temperatures are given in Table 1. Table 1 — Conditions of use/Classifications Water Supply
