DIN EN 287-6:2010-05

This standard specifies main requirements, limits, inspection conditions and acceptance requirements as well as related inspection documents of welders for welded cast iron parts and work pieces. It provides a set of technical rules for a systematic qualification test of a welder's skills, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body. The testing of a welder's skills shall be performed in accordance with the specifications given in this standard, unless a higher level skill test is applicable. The acceptance of a welder's skill according to DIN EN 287-6 implies practical experience and knowledge regarding the welding process, materials and safety requirements (see Annex C). This standard has to be used when certain requirements on part of a customer, testing or monitoring body or other organisation are postulated. This standard defines the qualification test of welders for the fusion welding of cast iron. The welding processes described in this document include those fusion welding processes which are designated as manual or partly mechanized welding. The standard does not cover fully mechanized and automated welding processes, see EN 1418. Cast iron materials which are covered by this standard are mentioned in 5.4. The certificates shall be issued under the responsibility of the examining body. This European Standard has been prepared by CEN/TC 190 "Foundry technology", WG 13 "Schweißen von Gusswerkstoffen" (WG 13 "Welding of cast iron"), in collaboration with CEN/TC 121/SC 2 "Qualification requirements for welding and allied processes personnel". On the national level the responsible Working Committee is NA 036-00-05 AA "Schweißen von Gusswerkstoffen" ("Welding of cast iron") of GINA.
