Iso (theInternational Organizationfor Standardization)isaworldwidefederationofnational standardsbodies (iso member bodies).The work of preparing International Standards is normally carried outthrough Iso technical committees. Each member body interested in a subject for which a technicalcommittee has been established has the right to be represented on that committee. Internationalorganizations, 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 ofelectrotechnicalstandardization.The procedures used to develop this document and those intended for its further maintenance aredescribed in the ISo/IEc Directives, Part 1. In particular, the different approval criteria needed for thedifferent types of Iso documents should be noted. This document was drafted in accordance with theeditorialrulesoftheIso/IEcDirectives,Part2(seewww.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject ofpatent rights.
