DIN EN 14587-3:2013-01 EN 14587-3:2012 (E) 4Introduction This part of EN 14587 has four main topics: requirements of a welding process; procedure approval for a fixed plant; ap
29、proval of other rail profiles or grades; weld production following approval. This European Standard satisfies the needs of the railway authority. The manufacturer should achieve the specified requirements of this European Standard. DIN EN 14587-3:2013-01EN 14587-3:2012 (E) 5 1 Scope This European St
30、andard specifies requirements for the approval of a welding process in a fixed plant, together with the requirements for subsequent welding production. This European Standard applies to new Vignole rails welded by flash butt welding to crossing components in a fixed plant, and intended for use on ra
