This standard applies to aluminothermic welds made on Vignole rails of 46 kg/m and above as contained in EN 13674-1: This standard specifies:  the system for training, testing and maintaining the skills of aluminothermic welders. It applies to those aluminothermic welding processes compliant with the requirements of EN 14730-1 "Railway applications – Track – Aluminothermic welding of rails – Part 1: Approval of welding processes". It requires that the system for training and testing of welders shall be approved by the relevant railway authority;  the systems and requirements for the approval of aluminothermic welding contractors. It applies to those contractors using aluminothermic welding processes compliant with the requirements of EN 14730-1 "Railway applications – Track – Aluminothermic welding of rails – Part 1: Approval of welding processes" and who employ welders who are in possession of a valid Permit to Weld as defined in Clause 4 of this standard;  the acceptance requirements for aluminothermic welds. It requires that weld inspectors are competent in aluminothermic weld inspection and are approved by the relevant railway authority. It covers the final inspection of aluminothermic welds for acceptance in track. It does not cover any previous inspections by welders or others.
