La CEI a pour objet defavoriser la coopration internationale pour toutes les questions de normalisation dans les domaines dellectricit et de llectronique. A

27、cet effet, la CEI, entre autres activits, publie des Normes Internationales.Leur laboration est confie des comits dtudes, aux travaux desquels tout Comit national intress par lesujet peut participer.

37、 for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IE

38、C publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in

39、 this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninte

40、rnational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, techn

41、ical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydiver

42、gence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) A

43、ttention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60986 has been prepared by IEC technical committee 20: Elec

44、triccables.This second edition cancels and replaces the first edition published in 1989 and its amendment(1993). It has been revised to accommodate rated voltages and materials in IEC 60502-2.The text of this standard is based on the following document:FDIS Report on voting20/398/FDIS 20/417/RVDFull

45、 information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.The committee has decided that the contents of this publication will remain unchanged unti
