18、mbly management plan FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning s
19、tandardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prepa
20、ration 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. IEC collaborates closely w
21、ith 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 on technical matters express, as nearly as possible, an international consensus of opinion on the relevant su
22、bjects 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 accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technic
23、al 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 international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent
24、 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 latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide co
25、nformity 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 should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its di
26、rectors, 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) and expenses aris
27、ing 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 publication. 9) Attention is
28、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. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstanc
29、es, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the
30、 future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62239-2, which is a technical specification, has been pre
31、pared by IEC Technical Committee 107: Process management for avionics. PD IEC/TS 62239-2:2017IEC TS 62239-2:2017 IEC 2017 5 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 107/288/DTS 107/293/RVDTS Full information on the voting for the ap
32、proval of this technical specification can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62239 series, published under the general title Process management for avionics M
33、anagement plan, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be rec
34、onfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. PD IEC/TS 62239-2:2017 6 IEC TS 62239-2:2017 IEC 2017 INTRODUCTION The purpose of this document is to define the requirements for developing an electronic commercial
35、 off the shelf (COTS) assembly management plan (CAMP), hereinafter also called the plan, to assure customers that all of the electronic COTS assemblies in the equipment of the plan owner are selected and applied in controlled processes, and that the technical requirements detailed in this document a
36、re accomplished. In general the owners of an electronic COTS assembly management plan are original (electronic) equipment manufacturers (OEMs) and system integrators for the aerospace, defence and high performance (ADHP) electronics industry. The objective is to define and document, as necessary, pr
37、ocesses to assure the adequacy of electronic COTS assemblies selected for use in electronic systems. This document states objectives to be accomplished; it does not specify how tasks are performed, specific data collected or reports issued. Those who prepare plans in compliance with this document ar
38、e encouraged to document processes that are the most effective and efficient for them in accomplishing the objectives of this document. In order to allow flexibility in implementing and updating the documented processes, plan authors are encouraged to refer to their own internal process documents in
39、stead of including detailed process documentation within their plans. Organizations that prepare such plans are called the plan owners and may prepare a single plan, and use it for all relevant products supplied by the organization, or may prepare a separate plan for each relevant product or custome

41、anagement plans (CAMPs) for the integration and management of electronic COTS assemblies (see 3.1.13 and 3.1.20) in electronic systems used in the ADHP markets where reliability is generally critical. NOTE 1 Best practices for managing the electronic components within the electronic assemblies are d
42、escribed in IEC TS 62239-1 and SAE EIA-STD-4899 which describe the electronic component management program (ECMP). In cases where the electronic components can be identified and managed at the component level, ECMP can be considered as an option to manage the components. NOTE 2 The distinction betwe
43、en an electronic component and an electronic assembly is provided by the definitions in Clause 3. This distinction between an electronic component and an electronic assembly is not always recognized by industry: for example, filters, contactors, power supply modules, relays, magnetic assemblies, etc
44、., can be considered as either components or assemblies. In each application it is considered a best practice for the user of this document to clarify this distinction. Depending on program or product line requirements and/or the technical characteristics of the electronic COTS assemblies and in agr
45、eement with the customer, the electronic COTS assembly management plans (CAMPs) could consider tailoring the requirements of this document. See Annex A. Although developed for the avionics industry, this document can be applied by other high performance and high reliability industries at their discr
