The work of preparing International Standards is normally carried out through isoO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. international organizations, governmental and non- governmental, in liaison with Iso, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (lEC)onallmattersofelectrotechnicalstandardization. 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. ISO/TC 2, Fasteners.
