27、 This document (EN 816:2017) 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 February
28、 2018, and conflicting national standards shall be withdrawn at the latest by February 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This doc
29、ument supersedes EN 816:1996. The main changes compares to the previous edition are: 1) water saving criteria were introduced; 2) the entire structure of the standard was revised; 3) normative references have been updated; 4) editorial changes and have been made throughout the entire document; 5) fi
30、gures were redrawn. According to the CEN-CENELEC Internal Regulations, the national standards organisations 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 Ma

32、potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard: 1) 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; 2) it should be noted th
33、at, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. BS EN 816:2017EN 816:2017 (E) 6 1 Scope This European Standard is applicable to single and mixer taps with automatic shut-off
34、for use with sanitary appliances installed in washrooms. It does not apply to urinal or WC flushing valves or valves which open automatically. The purpose of this standard is to specify the marking, identification, chemical/hygiene, dimensional, leaktightness, pressure resistance, hydraulic, mechani
35、cal endurance, and acoustical characteristics of automatic shut-off tapware. The tests described in all the standard are type tests (laboratory tests) and not quality control tests carried out during manufacture The conditions of pressure and temperature given in Table 1 apply: Table 1 Conditions fo
