This European Standard shall be given the status
30、 of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at the latest by June 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of
31、patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15091:2006. Significant technical differences between this edition and EN 15091:2006 are as follows: the introduction of a maximum voltage; the change of dimensi
32、onal characteristics (see 5.2); the change in minimum flow rates and hammer test (5.3.5 and 5.3.3). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, C
33、yprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the Uni
34、ted Kingdom. EN 15091:2013 ( E) DIN EN 15091:2014-036 Introduction This standard is relevant for electrically operated (opening and closing) sanitary tapware used with sanitary appliances, with a maximum voltage of 42 V AC / 72 V DC, in the enclosure of the tap. Such tapware can be operated by any e
35、lectrical source e.g. mains with a transformer, battery, etc. Flow and temperature regulation devices installed either upstream or downstream of the tapware are not covered by this specification. The purpose of this standard is to define requirements for the: 1) marking, identification, leak-tightne
36、ss, electrical and operational safety, mechanical performance and limitation of water hammer for electrical opening and closing tapware; 2) dimensional, hydraulic, endurance and acoustic characteristics; 3) procedure of tests in order to verify these characteristics. As for possible unfavourable eff
37、ects of the product to which this standard applies, on the quality of water intended for human consumption: 4) no information is provided by this standard on possible use restrictions of the product in any of the member states of the EU or EFTA; 5) it should be noted that, while awaiting the adoptio
38、n of verifiable European criteria, existing national regulations concerning the use and/or characteristics of this product remain in force.

There is usually no acoustic classification for tapware used in supply systems of Type 2 and no specifications governing the level of noise emissions from these water installations. If supply pressures are such that excessive noise is generated it is recommended that pressure or f
46、low regulators are fitted in the system. Or where practicable, tapware conforming to the appropriate acoustic classification are used.
