22、lectrotechnical 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 publishes International Standards, Technical Spec
23、ifications, 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 may participate in this preparatory work. Interna
24、tional, 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 agreement between the two organizations. 2) The forma
25、l 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 Publications have the form of recommendations for
26、 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 used or for any misinterpretation by any end user. 4)
27、 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 corresponding national or regional publication shall
28、 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 the latest edition of this publication. 7) No liabil
29、ity 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 indirect, or for costs (includ
30、ing 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 correct application of t
31、his 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. IEC 60641-3-1 has been prepared by IEC technical committee 15: Solid elect
32、rical insulating materials. This second edition cancels and replaces the first edition published in 1992. This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below: requirements for types B.0.3 and B.5.3 were added; the precompressed type B
33、3.1 was divided in B.3.1A and B.3.1B (higher flexibility); types B.6.1 has been replaced with a new type, but the designation has been kept; type B.7.1 has been deleted; the thickness relation of the properties has been simplified; 4 60641-3-1 IEC:2008 the values were adjusted to todays needs of us
34、ers. The text of this standard is based on the following documents: CDV Report on voting 15/390/CDV 15/439/RVC Full information on the voting for the approval 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
35、ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60641 series, under the general title Pressboard and presspaper for electrical purposes, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result
36、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 edition, or amended. 60641-3-1 IEC:2008 5 PRESSBOARD AND PRESSPAPER FOR ELECTRICAL PURPOSES Part 3: Sp

38、a mixture of sulphate wood pulp and cotton. Materials which conform to this specification meet 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 applicatio
39、n and not based on this specification alone. SAFETY WARNING It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. 2 Normative references The following referenced documents are indispensable for the application of
40、this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
