The International Organization for Standardizations (ISO) is a nongovernmental body with a mission to promote the development of standardization and related activities worldwide. Technical Committee 85 (TC85) deals with nuclear energy, nuclear technologies and radiological protection; standards relating to the transport of radioactive materials are included in the activities of Sub-Committee 5 (SC5: nuclear installations, processes and technologies).

WNTI focuses on three standards: ISO 12807, ‘Leakage testing on packages’, ISO 7195, ‘Packaging of Uranium Hexafluoride (UF6) for transport’ and ISO 10276 ‘Trunnions for packages used to transport radioactive material’. These standards are dealt with by the ISO Working Group 4 (WG4: Transportation of radioactive material). WNTI makes an effective contribution to ISO as a Category A Liaison Organisation and delivers Industry’s opinions via its participation in ISO/TC85/SC5/WG4 as an expert.
