COMMISSIONCOMMUNICATION NETWORKS AND SYSTEMSIN SUBSTATIONSPart 2:GlossaryFOREWORD1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprisingall 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 Specifications.Technical Reports,and Guides(hereafter referred to as IEC Publication(s).Their preparation is entrusted totechnical committees;any IEC National Committee interested in the subject dealt with may participate in thispreparatory work.International,governmental and non-governmental organizations liaising with the IEC alsoparticipate in this preparation.IEC collaborates closely with the International Organization for Standardization(ISO)in accordance 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 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 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 international 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 latter.5)IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with an IEC Publication6)All users should ensure that they have the latest

the publication of a technicalspecification whenthe required support cannot be obtained for the publication of an International Standard,despite repeated efforts,orthe subject is still under technical development or where,for any other reason,there is thefuture but no immediate possibility of an agreement on an International Standard.Technical specifications are subject to review within three years of publication to decidewhether they can be transformed into International Standards.IEC 61850-2,which is a technical specification,has been prepared by IEC technical committee57:Power system control
