21、n in the electrical andelectronic fields.To this end and in addition to other activities,the IEC publishes International Standards.Their preparation is entrusted to technical committees;any IEC National Committee interested inthe subject dealt with may participate in this preparatory work.Internatio
22、nal,governmental andnon-governmental organizations liaising with the IEC also participate in this preparation.The IECcollaborates closely with the Intenational Organization for Standardization(ISO)in accordance withconditions determined by agreement between the two organizations.2)The formal decisio
23、ns 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 recommendation
24、s for international use published in the form of standards,technicalreports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification,IEC National Committees undertake to apply-IEC InternationalStandards transparently to the maximum exte
25、nt possible in their national and regional standards.Anydivergence 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
