EN 10340:2007 (E) 3 Foreword This document (EN 10340:2007) has been prepared by Technical Committee ECISS/TC 31 “Steel castings”, 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of an identical text or by endorsement, at the latest by April 2008, and conflicting national standards shall be withdrawn at the latest by July 2009. This document has been prepared under a mandate M120 given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s) "Construction Products Directive (89/106/EEC)". For relationship with EU Directive(s) "Construction Products Directive (CPD)”, see informative Annex ZA, which is an integral part of this document. This document is intended to be read in conjunction with EN 1559-1:1997 and EN 1559-2:2000 and the referenced test Standards. 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 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s).

EN 10340:2007 (E) 4 Introduction This draft European Standard retains the same format for clauses as EN 1559-1:1997 and EN 1559-2:2000. It is intended to be used in conjunction with these standards. Where no text is given under a paragraph heading, the corresponding paragraph of EN 1559-1:1997 and EN 1559-2:2000 applies. The structure of this standard is as follows:  clauses and subclauses preceded by v indicate no additional conditions to EN 1559-11) and EN 1559-21);  clauses and subclauses marked with a single dot • indicate that the conditions shall be agreed at the time of enquiry and order in so far as such conditions do no conflict with the regulatory requirements of the European Union State or EFTA of destination;  subclauses marked with two dots •• indicate that conditions may be agreed at the time of enquiry and order (optional) in so far as such conditions do no conflict with the regulatory requirements of the European Union State or EFTA of destination;  subclauses without dot marking are a requirement of this standard.

1) When complementary information is given in a clause or subclause of this standard (versus the same clause or subclause of EN 1559-1:1997 or EN 1559-2:2000) it is preceded by "in addition to EN 1559".
