14、s(IEC National Committees).The object of the IEC is topromote international cooperation on all questions concerning standardization in the electrical andelectronic fields.To this end and in addition to other activities,the IEC publishes International Standards.Their preparation is entrusted to techn
15、ical committees;any IEC National Committee interested in thesubject dealt with may participate in this preparatory work.International,governmental andnon-governmental organizations liaising with the IEC also participate in this preparation.The IECcollaborates closely with the International Organizat
16、ion for Standardization(ISO)in accordance withconditions determined by agreement between the two organizations.2)The formal decisions or agreements of the IEC on technical matters,prepared by technical committees onwhich all the National Committees having a special interest therein are represented,express,as nearly aspossible,an international consensus of opinion on the subjects dealt with.3)They have the form of recommendations for international use published in the form of standards,technicalr
