Bibliography ili nse from IHS Not for Resale ISO14617-2:2002(E) Foreword Iso (the International Organization for Standardization) is a worldwide federation of national standards bodies (IsO 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. 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. Attention is drawn to the possibility that some of the elements of this part of Iso 14617 may be the subject of patent rights.
