32、onal Electrotechnical 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 electroni

33、c fields. To 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; a

34、ny IEC National Committee 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 Standar

35、dization (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 international consensus of opinion on the relevant subjects since each technical committee has repr

36、esentation from all interested IEC 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, IE

37、C cannot be held responsible for 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 publi

38、cations. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated 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

39、 IEC Publication. 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 committees and IEC National Committees for any personal in

40、jury, 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) Attention is drawn to the Normative references

41、 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 ident

42、ifying any or all such patent rights. International Standard IEC 61496-3 has been prepared by IEC technical committee 44: Safety of machinery Electrotechnical aspects, in collaboration with CENELEC technical committee 44X: Safety of machinery Electrotechnical aspects. This second edition cancels and

43、 replaces the first edition issued in 2001 and constitutes a technical revision. The most important changes and improvements compared to the first edition of this part of the standard are: extension of the range of detection capability covered by this part of the standard from 50 mm to 100 mm to the

44、 range of 30 mm to 200 mm; clarification of requirements for the selection of multiple detection zones (Clause A.10); 61496-3 IEC:2008 5 more detailed information about the use of an AOPDDR as a whole body trip device by extension of Clause A.12 and a new Clause A.13; improved description of the rel

45、ationship between ranging accuracy and probability of detection (Annex BB). This International Standard is to be used in conjunction with IEC 61496-1:2004. The text of this standard is based on the following documents: FDIS Report on voting 44/572/FDIS 44/578/RVD Full information on the voting for t

46、he 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. A list of all parts of IEC 61496 series, under the general title Safety of machinery Electro-sensitive protective equip

47、ment, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication wi

48、ll be reconfirmed, withdrawn, replaced by a revised edition, or amended. This standard has the status of a dedicated product standard and may be used as a normative reference in a dedicated product standard for the safety of machinery. 6 61496-3 IEC:2008 INTRODUCTION An electro-sensitive protective equipment (ESPE) is applied to machinery presenting a risk of personal injury. It provides protection by causing the machine to revert to a safe condition before a person can be placed in a hazardous situation. This part supplements or modifies the corresponding clauses in IEC 61496-1
