29、rol circuit devices and switching elements Requirements for proximity devices with defined behaviour under fault conditions (PDDB) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC
30、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, Technical Reports, P
31、ublicly 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, governmental and non-gov
32、ernmental 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 or agreements of IEC
33、 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 international use and are accep
34、ted 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 promote internation
35、al 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 indicated in the lat
36、ter. 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 conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users shou
37、ld 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 injury, property damage or other dama
38、ge 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 cited in this publication. Use of
39、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 identifying any or all such patent right
40、s. International Standard IEC 60947-5-3 has been prepared by subcommittee 17B: Low-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear. This second edition replaces the first edition published in 1999 and its amendment published in 2005. It is a technical re
41、vision. This edition includes the following significant technical changes with respect to the previous edition: a) general principles of IEC 61508 series; b) classification according to the requirements of IEC 62061; c) classification according to ISO 13849-1. This standard is to be read in conjunct
42、ion with IEC 60947-1, Low voltage switchgear and controlgear Part 1: General rules and IEC 60947-5-2, Low-voltage switchgear and 60947-5-3 IEC:2013 5 controlgear Part 5-2: Control circuit devices and switching elements Proximity switches. The provisions of Part 1 and Part 5-2 are only applicable to
43、this standard where specifically called for. The numbering of the subclauses of this standard is sometimes not continuous because it is based on the numbering of the subclauses of IEC 60947-1 or IEC 60947-5-2. The text of this standard is based on the following documents: FDIS Report on voting 17B/1
44、821/FDIS 17B/1826/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. A list of all parts in the IEC 60947 series, published under
45、the general title Low-voltage switchgear and controlgear, can be found on the IEC website. 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 specific pu
46、blication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60947-5-3 IEC:2013 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR Part 5-3: Control circuit devices and switching elements Requirements for proximity devices with defined behaviour under fau
47、lt conditions (PDDB) 1 General 1.1 Scope This part of IEC 60947 series provides additional requirements to those given in IEC 60947-5-2. It addresses the fault performance aspects of proximity devices with a defined behaviour under fault conditions (PDDB). It does not address any other characteristi
48、cs that can be required for specific applications. This standard does not cover proximity devices with analogue output. This Standard does not deal with any specific requirements on acoustic noise as the noise emission of control circuit devices and switching elements is not considered to be a relev
49、ant hazard. For a PDDB used in applications where additional characteristics, dealt with in other standards, are required, the requirements of all relevant standards apply. The use of this standard alone does not demonstrate suitability for the implementation of any specific safety related functionality. In particular, this standard does not provide requirements for the actuation characteristics of a PDDB, or for
