The work of preparing International Standards is normally carried out throughIsotechnicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnical 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. The procedures used to develop this document and those intended for its further maintenance are described in the ISo/lEC Directives, Part 1. In particular the different approval criteria needed for the different types of IsO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/lEC Directives, Part 2 (see www.iso.org/directives).
