38、selon les Directives ISO/CEI, Partie 3.TS 62098 IEC:2001 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION_EVALUATION METHODSFOR MICROPROCESSOR-BASED INSTRUMENTSFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotech

39、nical 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 International Standards. Their preparation

40、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 IEC collaborates closely with th

41、e 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, aninternational consensus of opinion on the relevant subjects

42、 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 and they are accepted by the Nat

43、ionalCommittees 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 Standard and the corresponding na

44、tional 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 possibility that some of the e

45、lements of this technical specification may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.The main task of IEC technical committees is to prepare International Standards. Inexceptional circumstances, a technical committee may prop

47、of an agreement on an International Standard.IEC 62098, which is a technical specification, has been prepared by subcommittee 65B:Devices, of IEC technical committee 65: Industrial-process measurement and control.This bilingual version (2001-05) replaces the English version.The text of this technica
