30、ctive opto-electronic protective devices (AOPDs) FOREWORD 1) The International 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 o
31、n 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, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC P
32、ublication(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, governmental and non-governmental organizations liaising with the IEC also participate in this preparation
33、. 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 international consensus o
34、f 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 international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are mad
35、e 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transpa
36、rently 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 indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent cer
37、tification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. 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 s
38、hall 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 injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including l
39、egal 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 cited in this publication. Use of the referenced publications is indispensable for the correct application of this p
40、ublication. 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. International Standard IEC 61496-2 has been prepared by IEC technical committee
41、 44: Safety of machinery Electrotechnical aspects, in collaboration with CENELEC technical committee 44X: Safety of machinery Electrotechnical aspects. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision. This edition includes the followi
42、ng significant technical changes with respect to the previous edition: a) Requirements have been corrected and made easier to understand. b) Test procedures have been revised to make them easier to perform and to improve repeatability. c) Guidance is provided for the evaluation and verification of A
43、OPDs using design techniques for which the test procedures of this part are not sufficient. 61496-2 IEC:2013 5 This standard has the status of a product family standard and may be used as a normative reference in a dedicated product standard for the safety of machinery. This standard is to be used i
44、n conjunction with IEC 61496-1:2012. This part supplements or modifies the corresponding clauses in IEC 61496-1. Where a particular clause or subclause of Part 1 is not mentioned in this Part 2, that clause or subclause applies as far as is reasonable. Where this part states “addition“, “modificatio
45、n“ or “replacement“, the relevant text of Part 1 is adapted accordingly. The text of this standard is based on the following documents: CDV Report on voting 44/651/CDV 44/670/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the ab
46、ove table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61496 series, published under the general title Safety of machinery Electro-sensitive protective equipment can be found on the IEC website. The committee has decided that th
47、e 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 specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTAN

49、ective equipment (ESPE) is applied to machinery that presents 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.
