28、 efficiently 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 fo

29、r the commercial aviation industry in the late 1960s, resulting in the publication of ATA-MGS-3 12. 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

30、 actions, 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, desi

31、gn 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 environme

32、nt, 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 consideration

33、s, 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. H

34、owever, 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, ope

35、rating 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 t

BS EN 60300-3-11:200960300-3-11 IEC:2009 7 DEPENDABILITY MANAGEMENT Part 3-11: Application guide Reliability centred maintenance 1 Scope This part of IEC 60300 provides guidelines for the development of failure management policies for equipment and structures using reliability ce

37、ntred maintenance (RCM) analysis techniques. This part serves as an application guide and is an extension of IEC 60300-3-10, IEC 60300-3-12 and IEC 60300-3-14. Maintenance activities recommended in all three standards, which relate to preventive maintenance, may be implemented using this standard. T

38、he RCM method can be applied to items such as ground vehicles, ships, power plants, aircraft, and other systems which are made up of equipment and structure, e.g. a building, airframe or ships hull. Typically, equipment comprises a number of electrical, mechanical, instrumentation or control systems

39、 and subsystems which can be further broken down into progressively smaller groupings, as required. This standard is restricted to the application of RCM techniques and does not include aspects of maintenance support, which are covered by the above-mentioned standards or other dependability and safe

40、ty standards. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
