26、300-3-11 IEC:2009 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ DEPENDABILITY MANAGEMENT Part 3-11: Application guide Reliability centred maintenance FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical
27、 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, Tec
28、hnical 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, governm
29、ental 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 or
30、 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 international
31、 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 p
32、romote 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 in
33、dicated 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 atta
34、ch 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 fees
35、) 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 publicatio
36、n. 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 60300-3-11 has been prepared by IEC technical committee 56: D
37、ependability. This second edition cancels and replaces the first edition, published in 1999, and constitutes a technical revision. The previous edition was based on ATA 1 -MGS-3; whereas this edition applies to all industries and defines a revised RCM algorithm and approach to the analysis process.
38、_ 1The Air Transport Association of America. 60300-3-11 IEC:2009 5 The text of this standard is based on the following documents: FDIS RVD 56/1312/FDIS 56/1320/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. A li
39、st of all parts in the IEC 60300 series, under the general title Dependability management 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.c
40、h“ in the data related to the specific publication. At this date, the publication will be: reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60300-3-11 IEC:2009 INTRODUCTION Reliability centred maintenance (RCM) is a method to identify and select failure management policies to eff
41、iciently and effectively achieve the required safety, availability and economy of operation. Failure management policies can include maintenance activities, operational changes, design modifications or other actions in order to mitigate the consequences of failure. RCM was initially developed for th
42、e commercial aviation industry in the late 1960s, resulting in the publication of ATA-MGS-3 1 2 . RCM is now a proven and accepted methodology used in a wide range of industries. RCM provides a decision process to identify applicable and effective preventive maintenance requirements, or management a
43、ctions, for equipment in accordance with the safety, operational and economic consequences of identifiable failures, and the degradation mechanism responsible for those failures. The end result of working through the process is a judgement as to the necessity of performing a maintenance task, design
44、 change or other alternatives to effect improvements. The basic steps of an RCM programme are as follows: a) initiation and planning; b) functional failure analysis; c) task selection; d) implementation; e) continuous improvement. All tasks are based on safety in respect of personnel and environment
45、, and on operational or economic concerns. However, it should be noted that the criteria considered will depend on the nature of the product and its application. For example, a production process will be required to be economically viable, and may be sensitive to strict environmental considerations,
46、 whereas an item of defence equipment should be operationally successful, but may have less stringent safety, economic and environmental criteria. Maximum benefit can be obtained from an RCM analysis if it is conducted at the design stage, so that feedback from the analysis can influence design. How
47、ever, RCM is also worthwhile during the operation and maintenance phase to improve existing maintenance tasks, make necessary modifications or other alternatives. Successful application of RCM requires a good understanding of the equipment and structure, as well as the operational environment, opera
48、ting context and the associated systems, together with the possible failures and their consequences. Greatest benefit can be achieved through targeting of the analysis to where failures would have serious safety, environmental, economic or operational effects. _ 2Figures in square brackets refer to
