The work of preparing International Standards is normally carried out through IsO technical com- right to be represented on that committee. International organizations, governmental and non-governmental, in liai- son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3 Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
