20、tion for standardization comprising all national electrotechnical 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
21、 publishes International Standards, Technical Specifications, 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
22、 may participate in this preparatory work. International, governmental 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 agr
23、eement 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 subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC
24、 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 technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are use
25、d 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 possible in their national and regional publications. Any divergence between any IEC Publication and the co
26、rresponding national or regional publication shall be clearly 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 th
27、e latest edition of this publication. 7) No liability shall 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
28、, whether direct or indirect, or for costs (including legal 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
29、 is indispensable for the correct application of this publication. 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 tec
30、hnical committees is to prepare International Standards. However, 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/TR 62125, w
31、hich is a technical report, has been prepared by IEC technical committee 20: Electric cables. This report should be used in conjunction with ISO Guide 64, with technical report ISO/TR 14062, and with IEC Guide 109. 4 TR 62125 IEC:2007 The text of this technical report is based on the following docum
32、ents: Enquiry draft Report on voting 20/868/DTR 20/880/RVC 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 been drafted in accordance with the ISO/IEC Directives, Part 2. The committee ha
33、s 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, the publication will be reconfirmed, withdrawn, replaced by a revised edi
34、tion, or amended. TR 62125 IEC:2007 5 INTRODUCTION The cable sector has always considered the impact of electric cables on the environment, in relation to their service conditions, and particularly for utility cables. Over the years, energy utilities have considerably increased their requirements to
35、 take into account the environmental impact of electric cables. IEC TC 20 is constantly reviewing its approach to the incorporation of environmental aspects into standards for electric cables and their components. Environmental considerations should be included in both design and redesign work with
36、respect to the raw materials used, energy consumption and emissions during production, end of life disposal or recycling, and in-service performance. For example, there is an environmental demand for more efficient operation of electric cables (lower transmission losses, reduced heating effects, and
37、, as a result, lower emission of greenhouse gases). There is some information on suitable cable design parameters to achieve lower losses. Unfortunately, diverse pressures from a number of interests usually result in the need to compromise in this area. 6 TR 62125 IEC:2007 ENVIRONMENTAL STATEMENT SP
38、ECIFIC TO IEC TC 20 ELECTRIC CABLES 1 Scope IEC/TR 62125, which is a technical report, is intended to give assistance to standard-writers of IEC Technical Committee 20, to take into account the relevant environmental aspects as far as they are specific to electric cables in normal use. It also assis
39、ts them to keep in mind a clear methodology when considering these aspects and when checking possible interaction of the normative requirements with the environment. Also, these guidelines assist standard-writers to avoid too simple or too stringent requirements that might not achieve a favourable g
40、lobal result. This technical report, by its very nature, is not prescriptive and does not limit innovation. NOTE 1 The term environment, as used in this report, differs from the term as used in those IEC standards dealing with the impact of environmental conditions on electrotechnical products (see
41、3.1). NOTE 2 As regards the impact of environmental conditions on the performance of products, reference is made to IEC 60068, IEC 60721 and IEC Guide 106. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the
42、 edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC Guide 109, Environmental aspects Inclusion in electrotechnical product standards ISO Guide 64, Guide for the inclusion of environmental aspects in product standards I
43、SO/TR 14062, Environmental management Integrating environmental aspects into product design and development 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 environment all attributes which affect the quality of life, such as water, air, and s
44、oil quality, conservation of energy and materials and avoidance of waste 3.2 life cycle consecutive and interlinked stages of the manufacture, installation, use, and disposal of a product, from raw material acquisition or generation of natural resources to the final disposal NOTE The raw material is
45、 considered to be the base raw material, incorporated in relevant products. 3.3 life cycle approach methodology of taking into account the life cycle of a product in order to assess the consequences on the environment TR 62125 IEC:2007 7 3.4 environmental impact of a product any change to the enviro
46、nment, whether adverse or beneficial, wholly or partially resulting from the life cycle of a product. 4 Implementation of TC 20s environmental policy 4.1 General principles Consideration should be given to the design and performance of the electric cable over its full life cycle. The choices made du
47、ring the design phase will largely decide what the impact will be during each phase of the products life cycle. Therefore, it is recommended: to take environmental aspects into account from the initial phases of product design; to avoid too simple or too stringent approaches in setting the acceptanc
48、e levels of performance requirements; to ensure that potentially safe alternative designs and alternative materials are afforded proper attention, and not excluded because of historical considerations; to optimize combinations of materials; to avoid materials and designs that will introduce harmful
49、effects to the external environment; to organize the feedback of experience which enhances continuous improvement of product performances. 4.2 Environmental aspects for cable standards To improve the approach to incorporating environmental aspects into standards, IEC TC 20 proposes to: promote IEC Guide 109 to its WGs and standard-writers; take into consideration, and evaluate, any suggestions and/or r
