7、ctrotechnical Commission(IEC)is a worldwide organization for standardization comprising all national electrotechnical committees(IEC National Committees).The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields.To
8、this end and in addition to other activities,IEC publishes International Standards,Technical Specifications,Technical Reports,Publicly Available Specifications(PAS)and Guides(hereafter referred to as“IEC Publication(s)”).Their preparation is entrusted to technical committees;any IEC National Committ
9、ee interested in the subject dealt with may participate in this preparatory work.International,governmental and non-governmental organizations liaising with the IEC also participate in this preparation.IEC collaborates closely with the International Organization for Standardization(ISO)in accordance
10、 with conditions determined by agreement between the two organizations.2)The formal decisions or agreements of IEC on technical matters express,as nearly as possible,an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested I
11、EC National Committees.3)IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense.While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate,IEC cannot be held responsible for the
12、 way in which they are used or for any misinterpretation by any end user.4)In order to promote international uniformity,IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications.Any divergence between any IEC
13、Publication and the corresponding national or regional publication shall be clearly indicated in the latter.5)IEC itself does not provide any attestation of conformity.Independent certification bodies provide conformity assessment services and,in some areas,access to IEC marks of conformity.IEC is n
14、ot responsible for any services carried out by independent certification bodies.6)All users should ensure that they have the latest edition of this publication.7)No liability shall attach to IEC or its directors,employees,servants or agents including individual experts and members of its technical c
15、ommittees and IEC National Committees for any personal injury,property damage or other damage of any nature whatsoever,whether direct or indirect,or for costs(including legal fees)and expenses arising out of the publication,use of,or reliance upon,this IEC Publication or any other IEC Publications.8
16、)Attention is drawn to the Normative references cited in this publication.Use of the referenced publications is indispensable for the correct application of this publication.9)Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.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.In exceptional circumstances,a technical
