19、nal electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. T
20、heir 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. The IEC collabor
21、ates 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 the IEC on technical matters express, as nearly as possible, an international consensus of opinion
22、on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and t
23、hey are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC St
24、andard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to
25、 the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60300-3-10 has been prepared by IEC technical committee 56: Dependability. Th
26、e text of this standard is based on the following documents: FDIS Report on voting 56/708/FDIS 56/718/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. IEC 60300 consists of the following parts, under the general t
27、itle: Dependability management: Part 1: Dependability programme management Part 2: Dependability programme elements and tasks Part 3: Application guide BSIEC60300310:20014 BSI 04-2001 This standard is intended to be used in conjunction with IEC 60300-2 and is laid out in the same format. It is also
28、necessary that this standard can be used without reference to IEC 60300-2. There are therefore some instances in the standard where there are clauses which have some similar content to IEC 60300-2 in order to provide continuity, but this has been kept to a minimum. This standard cancels and replaces
29、 sections 1 and 3 of IEC 60706-1 (1982). This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that the contents of this publication will remain unchanged until 2005. At this date, the publication will be reconfirmed; withdrawn; replaced by a
30、revised edition, or amended. BSIEC60300310:20015 BSI 04-2001 0 Introduction 0.1 Purpose The IEC 60300 1)series of standards and guides explain the procedures for implementing a Dependability Programme during the design and development of a product in order to achieve specified levels of dependabilit
31、y. IEC 60300-1 is the top-level standard which provides guidance on dependability programme management. IEC 60300-2 is the next level down which defines the tasks that need to be carried out and gives guidance on how they should be undertaken. IEC 60300-3 encompasses a series of application guides w
32、hich develop the tasks in IEC 60300-2 into specific areas. These then lead to further documents which describe the “tools“ to be used when applying a guide. IEC 60300-1 and IEC 60300-2 are written to provide a guide on dependability, and are predominantly centred on the reliability aspects. It was c
33、onsidered that a guide was required to link IEC 60300-2 to the existing standards on maintainability, that is the IEC 60706 series of guides on maintainability of equipment and other standards covering specific procedures used in maintainability programmes. The original IEC 60706 series is being upd
34、ated to ensure that there is no undue duplication with this guide, and IEC 60706 is intended to provide the tools for the procedures specified here. The relevant parts of IEC 60706 are referenced where they will provide further guidance. 0.2 Concept of maintainability Maintainability refers to the e
35、ase with which maintenance work can be done. It involves the process of ensuring that products can be easily and safely maintained and that the maintenance support requirement is minimized. When a product has a reasonably long life, the cost of operation and support during that life can greatly exce
36、ed the initial capital cost. The value to the customer of optimizing maintainability should be evident. Some effort and expense applied to achieving a product which can be easily and cheaply maintained will make very significant savings in the life cycle costs. The maintenance costs of a product are
37、 also dependent on the quantity in use. For a large fleet of equipment, such as trucks, even a small improvement in maintainability can render significant cost savings in the long term. When a product is to be sold on the open market, the concept of easy maintenance at low cost is an important consi
38、deration in the selection by the customer of equipment with low operating costs. _ 1) IEC 60300 (all parts), Dependability management. BSIEC60300310:20016 BSI 04-2001 DEPENDABILITY MANAGEMENT Part 3-10: Application guide Maintainability 1 Scope This International Standard, which forms part of the se
39、ries of standards in the IEC 60300-3 series, is the application guide for maintainability. It can be used to implement a maintainability programme covering the initiation, development and in-service phases of a product, which form part of the tasks described in IEC 60300-2. It provides guidance on h
40、ow the maintenance aspects of the tasks should be considered in order to achieve optimum maintainability. It should be noted that the full programme described in this standard would only be applied to a major complex product with the potential for long- term usage. For less complex maintainable prod
41、ucts, a simpler programme should be adopted by tailoring the programme to suit the degree of complexity and the requirements of the customer. The standard uses other IEC standards and guides, notably IEC 60706, as reference documents or tools to provide more detail as to how a task should be underta
42、ken. Contracts between customer and supplier will vary widely according to conditions and circumstances in different industries. This standard is written on the premise that a product is to be developed by a contractor from a basic concept for the particular requirements of a user when the product i
43、s considered to be a development item (DI). However, in many instances, where a product already exists and needs little or no development effort; it is a Non- development item (NDI) and the full maintainability programme as described in this standard will not be required. However, the principles lai
44、d down in the standard can be applied as required, by tailoring the maintainability programme to suit the needs of the project. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60300.
