This European Standard shall be given the status of a national standard, either by publication of an identical text or
25、 by endorsement, at the latest by October 2008, and conflicting national standards shall be withdrawn at the latest by January 2010. 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
26、for identifying any or all such patent rights. 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 Construction Products Directive (89/106/EEC). For relationship with EU Directive(s
27、), see informative Annex ZA, which is an integral part of this document. It also takes into account the EN 13369:2004 Common rules for precast concrete products.
