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".



EN 10340:2007 (E) 5 1 Scope This European Standard applies to steel castings:  for structural uses in buildings and civil engineering works. Its uses include housing and service buildings, bridges, roads, pipe network. In cases where castings are joined by welding by the founder, this European Standard applies. This European Standard does not apply in cases where castings are welded:  to wrought products (plates, tubes, forgings.);  or by non founders. 2 Normative references The following referenced documents are indispensable for the application of this document.
