This European Standard shall be given the status of a national standard, either by publication of an identical text
18、or by endorsement, at the latest by January 2011, and conflicting national standards shall be withdrawn at the latest by January 2011. 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 responsibl
19、e for identifying any or all such patent rights. This document supersedes EN 12735-1:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 97/23/EC Pressure Equipment
20、Directive (PED). For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 3 “Copper tubes (installation and industrial)“ to revise EN 12735-1:2001. EN 12735-
