The scope of this part is:
- To establish material requirements for cast austenitic manganese steel for fixed crossings and cradles for crossings with moveable parts designed to be welded or bolted to rails.
- To formulate codes of practice for inspection, testing of unmachined and machined heat-treated castings.
- To list the methods by which crossings should be identified and traced.
- To define limits of weld rectification by the supplier.
- Special requirements for pre-hardened crossings.Geometrical aspects, as machining tolerances and inspection of finished crossings are covered in the EN 13232-6 & -7 and therefore not part of this EN.This standard specifies the minimum requirements for cast manganese crossing components. Special applications as for instance tram systems may require different demands in certain paragraphs and have to be agreed between customer and supplier.
