[en] Criteria are identified for controlling the fabrication of metal components of shipping containers used for transporting radioactive materials. The criteria have been selected from the ASME Code and are based on the level of radioactive materials being transported and the nuclear safety function of the container's components. Criteria are identified for fabrication processes which are related to materials control, forming, heat treatment, examination and acceptance testing. Implementation of the criteria will ensure the structural integrity of shipping containers at levels consistent with the radioactive materials being transported. 14 references, 3 tables
