International organizations, governmental and non- governmental, in liaison with isO, also take part in the work. .ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International a vote. ISO/TC 2, Fasteners.
