18、que dpose de la Commission Electrotechnique Internationale 2 60763-1 IEC:2010 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ LAMINATED PRESSBOARD FOR ELECTRICAL PURPOSES Part 1: Definitions, classification and general requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a wor
19、ldwide organization 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
20、activities, IEC 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 sub
21、ject dealt with 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 d
22、etermined by agreement 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 Co
23、mmittees. 3) IEC 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 wh
24、ich they are used 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 Public
25、ation and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is n
26、ot responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the 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 techn
27、ical 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 out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
28、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 to the possibility that some of the elements of this IEC Publication may be the subjec
29、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60763-1 has been prepared by IEC technical committee 15: Solid electrical insulating materials. This second edition cancels and replaces the first edition published in 1983
30、. This edition constitutes a technical revision. The main changes with respect to the previous edition are as follows: the specification was brought in line with the second edition of IEC 60641-1(2007). The text of this standard is based on the following documents: CDV Report on voting 15/536/CDV 15
31、/566/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. 60763-1 IEC:2010 3 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. Future standards in this series will carry the new gene
32、ral title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. A list of all the parts in the IEC 60763 series can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stab
33、ility 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. 4 60763-1 IEC:2010 LAMINATED PRESSBOARD FOR ELECTRICAL PURPOSES Part 1: Def
34、initions, classification and general requirements 1 Scope This part of IEC 60763 contains the definitions required for the understanding of all three parts of IEC 60763, the classification of material into types, and the general requirements applicable to all material covered by the standard. Materi
35、als 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 application and not based on this specification alone. 2 Nor
36、mative 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 amendments) applies. IEC 60641-1:2007, Pressboard an
37、d presspaper for electrical purposes Part 1: Definitions and general requirements 3 Terms and definitions For the purposes of this document the following definitions apply: 3.1 pressboard board normally made on an intermittent board machine from pulp made entirely from vegetable origin of high chemi
38、cal purity. It is characterized by its relatively high density, even thickness, surface smoothness, high mechanical strength, flexibility, ageing resistance and electrical insulating properties. The surface may be smooth or textured 3.2 laminated pressboard board built up from sheets of pressboard b
39、onded with an adhesive 4 Classification Based on compositions and properties, this standard covers the types of laminated pressboard shown in Table 1. The designation of types is the same as that given in IEC 60641-1; in addition, “L” is shown for “laminated” (for example LB0.1). To the description
40、of the types some examples of known applications are added without implying any restriction on other possible applications.60763-1 IEC:2010 5 Table 1 Classification Type Subdivisions Example of application LB0 Pressboard of particularly high chemical purity LB0.1 100 % sulphate wood pulp LB0.2 100 %
