14、d This document (EN 10293:2015) has been prepared by Technical Committee ECISS/TC 111 “Steel castings and forgings”, 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 th
15、e latest by July 2015 and conflicting national standards shall be withdrawn at the latest by July 2015. 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 su
16、ch patent rights. This document supersedes EN 10293:2005. In comparison with EN 10293:2005, the following significant technical changes were made: Alignment with the structure of EN 1559-1:2011, “Founding - Technical conditions of delivery - Part 1: General“ and EN 1559-2:2014 “Founding - Technical
17、conditions of delivery - Part 2: Additional requirements for steel castings“; New grades (GE270, GE320 and GE360) added. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium,
18、 Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerlan

It should be used in conjunction with these standards. Where no text is given under a paragraph heading, the corresponding paragr
20、aph of EN 1559-1:2011 and EN 1559-2:2014 applies. The structure of this document is as follows: clauses and subclauses preceded by indicates 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 tim
21、e of enquiry and order; subclauses marked with two dots indicate that conditions may be agreed at the time of enquiry and order (optional); subclauses without dot marking are mandatory. 1) When a complementary information is given in a clause or subclause of this document (versus the same clause or
22、subclause of EN 1559-1:2011 or EN 1559-2:2014) it is preceded by “in addition to EN 1559-2:2014”. BS EN 10293:2015EN 10293:2015 (E) 5 1 Scope This European Standard applies to steel castings: for general engineering uses. Its uses include machinery (mechanical, electrical.), automotive industries, r
23、ailroad, armament, agricultural equipment, mining, etc. In cases where castings are joined by welding by the founder, this document applies. In cases where castings are welded: to wrought products (plates, tubes, forgings.), or by non-founders, this document does not apply. 2 Normative references Th
