40、prisingall 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 IEC publishes Internationa

41、l 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 this preparation. The I

42、EC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of o

43、pinion 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, technical reports or guides a

44、nd 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. Anydivergence between the IEC St

45、andard 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) Attention is drawn to the

46、 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 60702-2 has been prepared by IEC technical committee 20:Electric cables.This second

47、 edition of IEC 60702-2 cancels and replaces the first edition of IEC 60702-2published in 1986 and constitutes a technical revision.The text of this standard is based on the following documents:FDIS Report on voting20/491/FDIS 20/511/RVDFull information on the voting for the approval of this standar
