Over deze norm
This standard defines the laboratory tests and requirements for approval of an aluminothermic welding process using welds produced in workshop conditions. It applies to the joining of new, symmetrical, flat bottom rails of the same profile, same steel grade and a linear mass of 46 kg/m and above. The standard does not cover the testing required to demonstrate the suitability of a welding process for particular service conditions. The standard does not cover welds made between different rail sections, differently worn rails and different rail grades. In addition to the definitive requirements this standard also requires the items detailed in clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
