14、ERNATIONAL ELECTROTECHNICAL COMMISSION _ SUITABILITY OF TYPICAL ELECTRICAL INSULATING MATERIAL (EIM) FOR POLYMER RECYCLING FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National

15、 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, Technical Reports, Publicly

16、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, governmental and non- government

17、al 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 agreements of IEC on tec

18、hnical 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 use and are accepted by

19、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 promote international unif

20、ormity, 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 indicated in the latter. 5)

21、 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 attach to IEC or its director

22、s, 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 arising ou

23、t 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 drawn

24、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. However, a technical committee m

25、ay propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62392, which is a technical report, has been prepared by IEC technical committee 112: Evaluation and

26、 qualification of electrical insulating materials and systems. 1The text of this technical report is based on the following documents: Enquiry draft Report on voting 15/235/DTR 15/263/RVC _ 1Technical committee 112 was created by combining the activities of sub-committee 15E and techical committee 9

27、8. This project was initially developed in technical committee 15 and then transferred to technical committee 112. 4 TR 62392 IEC:2006(E) Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has b

28、een drafted in accordance with the ISO/IEC Directives, Part 2. 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

29、date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. TR 62392 IEC:2006(E) 5 SUITABILITY OF TYPICAL ELECTRICAL INSULATING MATERIAL (EIM) FOR POLYMER RECYCLING 1 Scope This Technical Repo

30、rt gives information for the assessment of factors associated with the polymer recycling and/or reuse of typical insulating materials in electrotechnical equipment. It gives information and assistance to developers and design engineers for assessment in selecting polymers and polymer combinations, a

31、nd is a contribution to the preservation of resources and the minimization of disposal costs at the end of a product life. The environmental compatibility of polymers must be assessed in the light of the function of the materials in the product and the total service life. An important aspect is the

32、recovery of the material at the end of the product life. The value level of material recycling as recovery option can be improved by incorporation of suitability for dismantling into the design of the article and the choice of insulating materials which are generally used. This document will cover m

33、aterial recycling only as part of recovery. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any ame
