14、ommittees (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, Techn
15、ical 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, governmen
16、tal 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 decisions or a
17、greements 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 international u
18、se 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 to pro
19、mote 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 clearly indi
20、cated 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 attach
21、 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 fees)
22、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 publication.
23、 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. The main task of IEC technical committees is to prepare International Standards. However,
24、a technical committee may 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 62422, which is a technical report, has been prepared by IEC technical commit
25、tee 15: Solid electrical insulating materials. The text of this technical report is based on the following documents: Enquiry draft Report on voting 15/346/DTR 15/356/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the ab
26、ove table. 4 TR 62422 IEC:2007(E) This publication has been 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“ i
27、n the data related to the specific publication. At this 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 62422 IEC:2007(E) 5 INTRODUCTION Production, use and disposal of product
28、s may cause serious environmental problems. Electrical and electronic products are among those that are suspected to have major impacts to the environment due to their use of energy, the variety of hazardous substances included and their volume on the market. It has to be noticed that the environmen
29、tal performance of these products is related to the characteristics of the insulating materials. Environmental aspects are present in each phase of the life cycle of these materials. For example, in some thermosetting resins, volatile hazardous chemical compounds are used in production phase and spr
30、ead during processing. On the other hand sometimes these additives allow a better insulation performance with a lower indirect impact due to lower electrical losses. Regarding the end of life, if these polymers are deposited at a landfill site, the complete degradation of the material may take more
31、than a century, and during this time span harmful additives may be leached from the landfill site. In order to minimize adverse environmental impacts of electrotechnical products, insulating materials selection should be conducted by engineers and designers including environmental considerations. Th
32、e environmental information related to the investigated insulating materials should be collected and processed, by suppliers, according to this document. The evaluation should be developed at the design stage, in respect of specific uses and with a life cycle perspective in mind. This means that the
33、 environmental characteristics of the materials used, which are collected and processed according to this document, should be compared with the environmental impacts due to the performance of the product and/or the system, with the product before making material selection, product design, and so on.
34、 In order to optimize the necessary trade-offs between fitness for use and environmental impact minimization, it is important to have appropriate and comparable, i.e. standardized, information on environmental aspects and impacts (direct and indirect) connected with insulating materials entire life
35、cycle. In particular, it is fundamental to have standardized information concerning the production phase, such as information related to the consumption of resources and the environmental impact, incurred during intermediate products manufacturing; the usage phase, such as information about harmful
36、substances actually released and the insulation performances; the end-of-life phase, such as the recyclability, the recoverability, the reusability, and cautions to be taken into account when landfilling or chemically recycling. The methodological framework for the environmental characterization of
37、insulating materials should be drafted in accordance with Life Cycle Assessment (LCA) (ISO 14040 standard) principles. 6 TR 62422 IEC:2007(E) ENVIRONMENTAL CHARACTERIZATION OF SOLID INSULATING MATERIALS 1 Scope This technical report gives framework guidelines for collecting environmental data of ins
38、ulating materials useful to engineers and designers of electrotechnical products for evaluating environmental impacts. It also provides a guideline for common format in environmental data reporting. This will enable producers to more easily evaluate the potential environmental impacts of those elect
39、rotechnical products using solid insulating materials. Moreover, it will allow a quick assessment of conformity to relevant electrotechnical product- related environmental regulations. 2 Normative references The following referenced documents are indispensable for the application of this document.

49、 performance of electrotechnical products should be described based on a Life Cycle Thinking (LCT) approach. LCT approach considers a products life-cycle and aims for a reduction of its cumulative environmental impacts. Although being based on the same principles as a Life Cycle Assessment (LCA), it is more qualitative and does not require the thorough data analysis that full scale LCA relies on.
