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. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard ("state of the art", for example), it may decide by a simplemajorityvoteofitsparticipatingmemberstopublishaTechnicalReport.ATechnicalReportisentirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.
