27、(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 this end and in addi
28、tion 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 Committee interes
29、ted 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 with
30、 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 IE
31、C 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
32、the 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 a
33、ny IEC 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 conform
34、ity. IEC is not 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
35、 of its technical committees 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 a
36、ny other IEC Publications. 8) 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
37、be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60050-351 has been prepared by IEC technical committee 65: Industrial-process measurement, control and automation, under the responsibility of IEC technical co
38、mmittee 1: Terminology. This fourth edition cancels and replaces the third edition published in 2006. It constitutes a technical revision. It has the status of a horizontal standard in accordance with IEC Guide 108. The text of this standard is based on the following documents: FDIS Report on voting
39、 1/2201/FDIS 1/2207/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 60050-351 IEC:2013 V In this part of the IEV, the terms and
40、 definitions are provided in French and English; in addition the terms are given in Arabic (ar), Chinese (zh), German (de), Spanish (es), Italian (it), Japanese (ja), Polish (pl) and Portuguese (pt). A list of all parts of the IEC 60050 series, published under the general title International Electro
41、technical Vocabulary, can be found on the IEC website and is available at http:/www.electropedia.org. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the
42、specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

43、1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation compose de lensemble des comits lectrotechniques nationaux (Comits nationaux de lIEC). LIEC a pour objet de favoriser la coopration internationale pour toutes les questions de normalisation dans les
44、 domaines de llectricit et de llectronique. A cet effet, lIEC entre autres activits publie des Normes internationales, des Spcifications techniques, des Rapports techniques, des Spcifications accessibles au public (PAS) et des Guides (ci-aprs dnomms “Publication(s) de lIEC“). Leur laboration est con
45、fie des comits dtudes, aux travaux desquels tout Comit national intress par le sujet trait peut participer. Les organisations internationales, gouvernementales et non gouvernementales, en liaison avec lIEC, participent galement aux travaux. LIEC collabore troitement avec lOrganisation Internationale
46、 de Normalisation (ISO), selon des conditions fixes par accord entre les deux organisations. 2) Les dcisions ou accords officiels de lIEC concernant les questions techniques reprsentent, dans la mesure du possible, un accord international sur les sujets tudis, tant donn que les Comits nationaux de l
47、IEC intresss sont reprsents dans chaque comit dtudes. 3) Les Publications de lIEC se prsentent sous la forme de recommandations internationales et sont agres comme telles par les Comits nationaux de lIEC. Tous les efforts raisonnables sont entrepris afin que lIEC sassure de lexactitude du contenu te
48、chnique de ses publications; lIEC ne peut pas tre tenue responsable de lventuelle mauvaise utilisation ou interprtation qui en est faite par un quelconque utilisateur final. 4) Dans le but dencourager luniformit internationale, les Comits nationaux de lIEC sengagent, dans toute la mesure possible, appliquer de faon transparente les Publications de lIEC dans leurs publications nationales et rgionales. Toutes divergences entre toutes Publications de lIEC et toutes publications nationales ou rgionales correspondantes doivent tre i
