27、nical 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

28、, Technical 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, go

29、vernmental 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 decision

30、s or 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 internati

31、onal 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

32、to promote 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 clearl

33、y indicated 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

34、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 damage of any nature whatsoever, whether direct or indirect, or for costs (including legal

35、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 the referenced publications is indispensable for the correct application of this public

36、ation. 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 62402 has been prepared by IEC technical committee 56: De

37、pendability. The text of this standard is based on the following documents: FDIS Report on voting 56/1189/FDIS 56/1205/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 accordan

38、ce with the ISO/IEC Directives, Part 2. 62402 IEC:2007 5 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.ch“ in the data related to the specific publication. At this date,

39、the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 6 62402 IEC:2007 INTRODUCTION Obsolescence affects all products and it impacts upon all stages of their life. The term product includes capital equipment; infrastructure; consumer durables; consumables; softwa

40、re products. Obsolescence is inevitable and it cannot be avoided, but forethought and careful planning can minimize its impact and its potential high costs. The objective of obsolescence management is to ensure that obsolescence is managed as an integral part of design, development, production and i

41、n-service support in order to minimize cost and detrimental impact throughout the product life cycle. Obsolescence presents itself in two ways: the item is no longer suitable for current demands, or the item is no longer available from the original manufacturer, e.g. due to economic constraints. Fro

42、m the users point of view, obsolescence then manifests itself as difficulty in obtaining supplies. If the end-user is the general public, it will be in the interest of the supplier to protect his brand image by having a defined obsolescence policy. Commercial-off-the-shelf (COTS) products and custom

43、 designed items, e.g. new design tools and new production processes, tend to have a much shorter life in terms of availability and supportability than in the past. With the increased use of commercial items in complex products expecting to have a long life cycle, it has become essential to include o

44、bsolescence management within programme plans from the earliest stages. Furthermore environmental considerations have the potential to affect the use of some materials during the life of the product and should be considered from the outset. Obsolescence management is essential to achieve optimum cos

45、t-effectiveness throughout the life cycle of a product. The purpose of this standard is to provide guidance on planning a cost effective obsolescence management process that takes into account essential factors to ensure product life cycle costs are considered and applied. Obsolescence management sh

46、ould also include the maintenance of the relevant knowledge and skill base sets. Clause 4 provides overview of the process and its relation to others. Clauses 5, 6 and 8 give guidance on management responsibility, resources, measurement and improvement with regard to obsolescence management. Clause

47、7 gives guidance on planning, strategies and options described for hardware (including integral software). Clause 9 gives guidance on planning, strategies and options for software that is separable from its hardware. 62402 IEC:2007 7 OBSOLESCENCE MANAGEMENT APPLICATION GUIDE 1 Scope This Internation

48、al Standard gives guidance for establishing a framework for obsolescence management and for planning a cost-effective obsolescence management process that is applicable through all phases of the product life cycle, the term product includes: capital equipment; infrastructure; consumer durables; cons

49、umables; software products. Obsolescence management covers the following areas: a) design of new products; b) new technology insertion into existing products; c) support and maintenance of legacy products. 2 Normative references The following referenced documents are indispensable for the application of this document.
