This European Standard shall

40、 be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2015 and conflicting national standards shall be withdrawn at the latest by November 2015. Attention is drawn to the possibility that some of the elements of this docu

41、ment 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 89:1999. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Associati

42、on, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, Annex ZB or Annex ZC, which are integral parts of this document. The present standard deals with: safety; rational use of energy; fitness for purpose. It gives specific requir

43、ements relative to: appliances with burners with a fan; combustion products discharge orifice closure devices; type C water heaters with a fan incorporated in the combustion air supply circuit or in the combustion products evacuation circuit; condensing water heaters; measurement of NOxemissions of

44、water heaters; the metallic, plastic and other non-metallic materials that are used in water heaters and which come into contact with water intended for human consumption. It is intended to ensure that products of this kind complying with these requirements meet current technological development and

45、 requirements with regard to the service life of the water heaters and their physiological suitability; the growth of microorganism on materials in contact with drinking water. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are boun

46、d 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
