7、national electrotechnical committees(IEC National Committees).The object of 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,IEC publishes International Standards,Technical S
8、pecifications,Technical Reports,Publicly Available Specifications(PAS)and Guides(hereafter referred to as?IECPublication(s)?).Their preparation is entrusted to technical committees;any IEC National Committee interestedin the subject dealt with may participate in this preparatory work.International,g
9、overnmental and non-governmental organizations liaising with the IEC also participate in this preparation.IEC collaborates closelywith the International Organization for Standardization(ISO)in accordance with conditions determined byagreement between the two organizations.2)The formal decisions or a
10、greements of IEC on technical matters express,as nearly as possible,an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3)IEC Publications have the form of recommendations for international use and
11、 are accepted by IEC NationalCommittees in that sense.While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate,IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4)In order to promote internat
12、ional uniformity,IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications.Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latte
