20、ssboard, Types LB3.1A.1 and LB3.1A.2 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 international co-operation on all questi
21、ons 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 (hereafter referred to as “IEC Publication(s
22、)”). 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 participate in this preparation. IEC colla
23、borates 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, an international consensus of opinion o
24、n 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 all reasonable efforts are made to ensure
25、 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 apply IEC Publications transparently to t
26、he 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 of conformity. Independent certification
27、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 publication. 7) No liability shall attach
28、 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)
29、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.
30、 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 60763-3-1 has been prepared by IEC technical committee 15: Soli
31、d electrical 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 the new properties in Part 2 have been integrated;
32、specifications for type LB3.3.1 and LB3.3.2 have been deleted. 60763-3-1 IEC:2010 3 The text of this standard is based on the following documents: CDV Report on voting 15/537/CDV 15/567/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicate
33、d in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. Future standards in this series will carry the new general 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 p
34、arts 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 stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the
35、publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 4 60763-3-1 IEC:2010 LAMINATED PRESSBOARD FOR ELECTRICAL PURPOSES Part 3: Specifications for individual materials Sheet 1: Requirements for laminated precompressed pressboard, Types LB3.1A.1 and LB3.1A.2 1 Scope T
36、his sheet of IEC 60763-3 gives the requirements for laminated precompressed boards comprised of 100 % sulphate wood pulp. 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
37、 the actual requirements necessary for adequate performance in that application and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undat
38、ed references, the latest edition of the referenced document (including any amendments) applies.
