EN 15091:2013 (E) 5 Foreword This document (EN 15091:2013) has been prepared by Technical Committee CEN/TC 164 “Water Supply”, the secretariat of which is held by AFNOR. This European Standard shall be given the status 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of an identical text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at the latest by June 2014.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 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 dimensional 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, Cyprus, 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 United Kingdom. SIST EN 15091:2014

EN 15091:2013 (E) 6 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 electrical 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-tightness, 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 effects 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 adoption of verifiable European criteria, existing national regulations concerning the use and/or characteristics of this product remain in force. Requirements for different products are defined in different clauses of this standard as illustrated in Table 1. Table 1 — Identification of the clauses of this standard

EN 15091:2013 (E) 7 1 Scope The purpose of this European Standard is to define requirements for marking, identification, leaktightness, electrical and operational safety and mechanical resistance for sanitary tapware with opening and closing controlled electronically. The conditions of use for the supply system type are specified in Table 2: Table 2 — Conditions of use Water supply system

Limits of use Recommended limits of operation Tapware with normally open or normally closed (monostable) solenoid valves Tapware with latching (bistable) solenoid valves Tapware with normally open or normally closed (monostable) solenoid valves Tapware with latching (bistable) solenoid valves Type 1 (see Figure 1) Minimum dynamic pressure 0,05 MPa (0,5 bar) 0,05 MPa (0,5 bar) (0,1 to 0,5) MPa [(1 to 5) bar] (0,1 to 0,5) MPa [(1 to 5) bar] Maximum static pressure 1 MPa (10 bar) 1 MPa (10 bar) 1 MPa (10 bar) 0.8 MPa (8 bar) Type 2 a (see Figure 2) Minimum dynamic pressure 0,01 MPa (0,1 bar) 0,01 MPa (0,1 bar) (0,01 to 0,2) MPa [(0,1 to 2) bar] (0,01 to 0,2) MPa [(0,1 to 2) bar] Maximum static pressure 1 MPa (10 bar) 1 MPa (10 bar) 0.8 MPa (8 bar) 0.6 MPa (6 bar) Temperature of the water ≤ 75 °C ≤ 75 °C ≤ 65 °C ≤ 65 °C a For Type 2, the manufacturer is to declare the minimum operating pressure at which opening, closing and the specified flow rate can be obtained. 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 flow regulators are fitted in the system. Or where practicable, tapware conforming to the appropriate acoustic classification are used.

Annex B lists possible consequences of using a product outside its recommended operating range. SIST EN 15091:2014
