22、Specifications for individual materials Sheet 8: Resins for cable accessories 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
23、 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 Available Specifications (PAS) and Guides (he
24、reafter 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- governmental organizations liaising with the IEC also p
25、articipate 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 technical matters express, as nearly as possible
26、, 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 IEC National Committees in that sense. While
27、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 uniformity, IEC National Committees undertake to
28、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) IEC itself does not provide any attestation
29、of conformity. Independent certification bodies provide conformity 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
30、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, whether direct or indir
31、ect, 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 is indispensable for the
32、 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. International Standard IEC 60455-3-8 has been pre
33、pared by IEC technical committee 15: Solid electrical insulating materials, in collaboration with working group 11 of Cenelec technical committee 20. The text of this standard is based on the following documents: FDIS Report on voting 15/701/FDIS 15/711/RVD Full information on the voting for the app
34、roval of this standard 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. 4 60455-3-8 IEC:2013 A list of all the parts in the IEC 60455 series, published under the general title Resin based reactive
35、compounds used for electrical insulation, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At th
36、is date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60455-3-8 IEC:2013 5 INTRODUCTION This part of IEC 60455-3-8 is one of a series which deals with specifications for reactive compounds and their components for electrical insulation. This series consi
37、st of three parts: Part 1: Definitions and general requirements (IEC 60455-1); Part 2: Methods of test (IEC 60455-2); Part 3: Specifications for individual materials (IEC 60455-3) IEC 60455-3-8 consists of one of the sheets comprising Part 3 as follows: Sheet 8: Resins for cable accessories 6 60455-
38、3-8 IEC:2013 RESIN BASED REACTIVE COMPOUNDS USED FOR ELECTRICAL INSULATION Part 3: Specifications for individual materials Sheet 8: Resins for cable accessories 1 Scope This sheet 8 of IEC 60455-3 gives the requirements for resins for power cable accessories which conform to this specification and m
39、eet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not on this specification alone. 2 Normative references The following documents, in w
