41、OTECHNICAL COMMISSION_SAFETY OF EQUIPMENT ELECTRICALLY CONNECTEDTO A TELECOMMUNICATION NETWORKFOREWORD1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the

42、 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, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committ

43、ee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in acco

44、rdance with conditions determined by agreement between the twoorganizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all in

45、terested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote internat

46、ional unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the

47、latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof p

48、atent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 62151 has been prepared by IEC technical committee 74: Safetyand energy efficiency of information technology equipment.This standard cancels and replaces IEC Guide 105, published in 1985.It has the status of a basic safety publication in accordance with IEC Guide 104 andISO/IEC Guide 51.The text of this standard is based on the following documents:FDIS Report on voting74/565/FDIS 74/574/RVDFull information on the voting for the approval of this stan
