Foreword

ISO(theInternationalOrganizationforStandardization)isaworldwidefederationofnationalstandardsbodies(ISOmember bodies). Thework of preparing International Standards is normally carried out through ISOtechnicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnicalcommitteehasbeenestablishedhastherighttoberepresentedonthatcommittee.Internationalorganizations,governmentalandnon-governmental,inliaisonwithISO,alsotakepartinthework.ISOcollaboratescloselywiththeInternationalElectrotechnicalCommission(IEC)onallmattersofelectrotechnicalstandardization.

InternationalStandardsaredraftedinaccordancewiththerulesgivenintheISO/IECDirectives,Part2.

Themain taskof technicalcommittees is toprepare InternationalStandards.Draft InternationalStandardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternationalStandardrequiresapprovalbyatleast75%ofthememberbodiescastingavote.
