The structure of this standard is as follows: clauses and subclauses preceded by 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
19、 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 cond
20、itions 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 E

DIN EN 10340:2008-01 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
22、, 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
