foreword
iso (the international organization for standardization) is a worldwide federation of national standards bodies
(iso member bodies). the work of preparing international standards is normally carried out through iso
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 (iec) on all matters of electrotechnical standardization.
international standards are dratted in accordance with the rules given in the iso/iec 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.
