25、ethodology for the achievement of functional safety of electrical and electronic systems including equipment with regard to electromagnetic phenomena FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnic

26、al 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 addition to other activities, IEC publishes International Standards, Technical Specifications, T

27、echnical 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 interested in the subject dealt with may participate in this preparatory work. International, gover

28、nmental 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 conditions determined by agreement between the two organizations. 2) The formal decisions o

29、r 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 IEC National Committees. 3) IEC Publications have the form of recommendations for internationa

30、l 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 way in which they are used or for any misinterpretation by any end user. 4) In order to

31、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 Publication and the corresponding national or regional publication shall be clearly i

32、ndicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall att

33、ach to IEC or its directors, employees, servants or agents including individual experts and members 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 fee

34、s) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any 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 publicati

35、on. 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 exc

36、eptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other

37、reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC/TS 61000-1-2, which is a technical speci

38、fication, has been prepared by technical committee 77: Electromagnetic compatibility. It has the status of a basic safety publication in accordance with IEC Guide 104.

39、0-1-2 IEC:2008(E) 5 This second edition cancels and replaces the first edition published in 2001 and constitutes a technical revision. The main changes are the following. For safety-related systems that use electrical, electronic or programmable electronic technologies, the technical information, de

40、finitions, terminology and text of this second edition have been aligned to IEC 61508. Risk assessment requirements and methodologies have been deleted from this document, so as not to duplicate or clash with IEC 61508. It now makes a clear distinction between complete safety-related systems and ite

41、ms of equipment that might be used in such systems, and clarifies its application by the different types of end-users. This technical specification focuses more on appropriate design methods, and their verification and validation. The methodology for assessing and specifying electromagnetic environm

42、ents has been extended. The combination of electromagnetic and physical/climatic influences are taken into account. The text of this technical specification is based on the following documents: Enquiry draft Report on voting 77/356/DTS 77/359A/RVCFull information on the voting for the approval of th

43、is technical specification 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. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date i

44、ndicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may

45、 be issued at a later date.

46、siderations (introduction, fundamental principles) Definitions, terminology Part 2: Environment Description of the environment Classification of the environment Compatibility levels Part 3: Limits Emission limits Immunity limits (insofar as they do not fall under the responsibility of the product co

48、lished either as international standards, technical specifications or technical reports, some of which have already been published as sections. Others will be published with the part number followed by a dash and completed by a second number identifying the subdivision (example: IEC 61000-3-11). Par

49、ticular considerations for IEC 61000-1-2 The function of electrical or electronic systems should not be affected by external influences in a way that could lead to an unacceptable risk of harm to the users, other persons, animals or property. A comprehensive safety analysis should consider various factors of climatic, mechanical, electrical nature and reasonably foreseeable misuse. Electromagnetic disturbances are present in most environments and should therefore be consider
