The difference type is noted on the first lineof the National Difference in the sta

27、ndard. The standard may not include all types of these NationalDifferences.DR These are National Differences based on the national regulatory requirements.D1 These are National Differences which are based on basic safety principles and requirements,elimination of which would compromise safety for co

28、nsumers and users of products.D2 These are national differences from IEC requirements based on existing safety practices. Theserequirements reflect national safety practices, where empirical substantiation (for the IEC or nationalrequirement) is not available or the text has not been included in the

29、 IEC standard.DC These are National Differences based on the component standards and will not be deleted untila particular component standard is harmonized with the IEC component standard.DE These are National Differences based on editorial comments or corrections.Each national difference contains a

30、 description of what the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition / Add - An addition entails adding a complete new numbered clause, subclause,table, figure, or annex. Add

31、ition is not meant to include adding select words to the base IECtext.Modification / Modify - A modification is an altering of the existing base IEC text such as theaddition, replacement or deletion of certain words or the replacement of an entire clause,subclause, table, figure, or annex of the bas

32、e IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause,subclause, table, figure, or annex without any replacement text.SEPTEMBER 20, 2011 UL 61496-2 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULINT

33、ERNATIONAL ELECTROTECHNICAL COMMISSIONSAFETY OF MACHINERY ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT Part 2, ParticularRequirements for Equipment Using Active Opto-Electronic Protective Devices (AOPDs)Foreword (IEC)1) The IEC (International Electrotechnical Commission) is a worldwide organization for st

34、andardizationcomprising all national electrotechnical committees (IEC National Committees). The object of the IEC is topromote international co-operation on all questions concerning standardization in the electrical andelectronic fields. To this end and in addition to other activities, the IEC publi

35、shes International Standards.Their preparation is entrusted to technical committees; any IEC National Committee interested in thesubject dealt with may participate in this preparatory work. International, governmental andnon-governmental organizations liaising with the IEC also participate in this p

36、reparation. The IECcollaborates closely with the International Organization for Standardization (ISO) in accordance withconditions determined by agreement between the two organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternation

37、al consensus of opinion on the relevant subjects since each technical committee hasrepresentation from all interested National Committees.3) The documents produced have the form of recommendations for international use and are published inthe form of standards, technical reports or guides and they a

38、re accepted by the National Committees inthat sense.4) In order to promote international unification, IEC National Committees undertake to apply IECInternational Standards transparently to the maximum extent possible in their national and regionalstandards. Any divergence between the IEC Standard an

39、d the corresponding national or regionalstandard shall be clearly indicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsiblefor any equipment declared to be in conformity with one of its standards.6) Attention is drawn to the possibil

40、ity that some of the elements of this International Standard may be thesubject of patent rights. The 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 44: Safety ofmachinery Electrotechnical

41、 aspects, in collaboration with CENELEC technical committee 44X: Safety ofmachinery Electrotechnical aspectsThe text of this standard is based on the following documents:FDIS Report on voting44/2O8/FDIS 44/212/RVDFull information on the voting for the approval of this standard can be found in the re

43、jury. It provides protection by causing the machine to revert to a safe condition before a person can beplaced in a hazardous situation.This part of International Standard IEC 61496 provides general design and performance requirements ofESPEs for use over a broad range of applications. Essential fea

44、tures of equipment meeting therequirements of this standard are the appropriate level of safety-related performance provided and thebuilt-in periodic functional checks/self-checks-that are specified to ensure that this level of performance ismaintained.This part supplements or modifies the correspon

45、ding clause in IEC 61496-1.Where a particular clause or subclause of part 1 is not mentioned in this part 2, that clause or subclauseapplies as far as is reasonable. Where this part states addition, modification or replacement, therelevant text of part 1 is to be adapted accordingly.This standard ha

46、s the status of a product family standard and may be used as a normative reference ina dedicated product standard for the safety of machinery.Each type of machine presents its own particular hazards and it is not the purpose of this standard torecommend the manner of application of the ESPE to any p

47、articular machine. The application of the ESPEshould be a matter for agreement between the equipment supplier, the machine user and the enforcingauthority; in this context, attention is drawn to the relevant guidance established internationally, forexample ISO/TR 12100.JANUARY 29, 2002 UL 61496-2 9U

Special attention is directed to features that ensure an appropriatesafety-related performance is achieved. An ESPE may include optional safety-related functions, therequirements for which are given in annex A of part 1.This part does not s
