Foreword (the International Organization for Standardization) is a worldwide federation of national standards bodies ( member bodies). The work of preparing International Standards is normally carried out through 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, also take part in the work. collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the /IEC Directives, Part 1. In particular the different approval criteria needed for the different types of documents should be noted.
