International IsO collaborates closelywiththeInternational Electrotechnical Commission(IEC)on allmatters of electrotechnicalstandardization. The procedures used to develop this document and those intended for its further maintenance are described intheIso/IEcDirectives,Part 1.Inparticularthedifferentapproval criterianeededforthe different types of IsO documents should be noted.This document was drafted in accordancewith the editorialrulesoftheISO/IEcDirectives,Part2(seewww.iso.org/directives).
