19、 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 questions concerning standardization in the electrical and electronic fi

20、elds. 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)”). Their preparation is entrusted to technical committees; any I

21、EC 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 collaborates closely with the International Organization for Standardiza

22、tion (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 on the relevant subjects since each technical committee has represen

23、tation 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 that the technical content of IEC Publications is accurate, IEC ca

24、nnot 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 the maximum extent possible in their national and regional publicati

25、ons. Any divergence between any IEC Publication and the corresponding 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

26、 Publication. 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 technical committees and IEC National Committees for any personal injury

27、 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 Publications. 8) Attention is drawn to the Normative references cit

28、ed 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 subject of patent rights. IEC shall not be held responsible for identifyi

29、ng any or all such patent rights. International Standard IEC 60641-1 has been prepared by IEC technical committee 15: Solid electrical insulating materials. This second edition cancels and replaces the first edition published in 1979 and amendment 1 (1993). This edition constitutes a technical revis

30、ion. The main changes with respect to the previous edition are listed below: the kind of surface finish shall no longer be specified in the standard; fixed nominal thicknesses have been replaced by preferred thicknesses; types B.6 and P.6 have been replaced, but the designations have been kept; type

31、s B.7 and P.7 have been deleted. 4 60641-1 IEC:2008 This bilingual version (2008) replaces the English version. The text of this standard is based on the following documents: CDV Report on voting 15/352/CDV 15/388/RVC Full information on the voting for the approval of this standard can be found in t

32、he report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60641 series, under the general title Pressboard and presspaper for e

33、lectrical 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 date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the

34、publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60641-1 IEC:2008 5 PRESSBOARD AND PRESSPAPER FOR ELECTRICAL PURPOSES Part 1: Definitions and general requirements 1 Scope This part of IEC 60641 contains definitions related to a classification of, and the general

35、 requirements to be fulfilled by, pressboard and presspaper for electrical purposes. 2 Terms and definitions 2.1 pressboard board normally made on an intermittent board machine from pulp made entirely from vegetable origin of high chemical purity. It is characterized by its relatively high density,

36、even thickness, surface smoothness, high mechanical strength, flexibility, ageing resistance and electrical insulating properties. The surface may be smooth or textured 2.2 presspaper multilayer paper made by a continuous process from pulp entirely from vegetable origin and of high chemical purity.

37、It is characterized by its density, even thickness, surface smoothness, high mechanical strength, ageing resistance and electrical insulating properties 2.3 calendered pressboard or presspaper, which is subsequently treated with a calender 2.4 pre-compressed pressboard to which heat has been applied

38、 during pressing 2.5 glazed pressboard or presspaper to which lustre has been imparted. The lustre may be imparted by any appropriate drying or mechanical finishing process Based on ISO vocabulary of paper terms. 3 Classification Based on compositions and properties, this standard covers the types o

39、f pressboard or presspaper shown in Table 1. To the description of the types, some examples of known applications are added without implying any kind of restriction on other possible applications. 6 60641-1 IEC:2008 4 General requirements 4.1 Composition All types of pressboard and presspaper covere

40、d by this standard shall be made entirely from vegetable fibres. All types shall be free from extraneous material and adhesive and shall, where necessary, contain a suitable dyestuff. NOTE The absence of contaminants such as metallic, inorganic and organic particles indicates the immaculateness of t

41、he material. Many of the types listed in Table 1 are specified as made from “sulphate wood pulp“. This raw material is used in order to enable appropriate chemical purity and mechanical properties to be achieved (excluding, for example, mechanical pulps). Advances in pulp technology have enabled the

42、 requisite properties to be obtained by more environmentally satisfactory processes, which cannot be described as “the sulphate process“. The term “sulphate wood pulp“ in Table 1 is intended to include such materials. In order to give satisfactory performance, it is necessary for the pulp to have a

43、high degree of polymerisation (DP) similar to that of unbleached sulphate pulp of high quality, and to be unbleached. The pulp must be capable of similar properties to sulphate pulp in all other respects. 4.2 Finish Pressboard or presspaper shall have a finish as agreed between purchaser and supplie

44、r. 4.3 Machineability All pressboard shall be capable of being sheared. Pressboard and presspaper of a thickness of 3,0 mm or less shall also be capable of being punched without showing ragged edges. The operation shall be carried out in accordance with the recommendations of the manufacturer. 5 Dim

45、ensions Thickness The preferred nominal thickness (in millimetres) of the pressboard and presspaper shall be one of the following: Presspaper: 0,075 - 0,10 - 0,13 - 0,15 - 0,18 - 0,20 - 0,25 - 0,30 - 0,40 - 0,50 - 0,60 - 0,80 Pressboard: 0,8 - 1,0 - 1,5 - 2,0 - 2,5 - 3,0 - 4,0 - 5,0 - 6,0 - 7,0 - 8,

46、0 Other thicknesses are possible. The tolerances on thickness are to be found in IEC 60641-3. 6 Conditions of supply The pressboard and presspaper shall be placed in a packing which ensures adequate protection during transport, handIing and storage. 60641-1 IEC:2008 7 A consignment of pressboard or

47、presspaper shall be legibly and indelibly marked with the following information. a) Manufacturers name or trademark, if any. b) Type of pressboard or presspaper as given in Table 1 c) Nominal thickness. d) Sheet size or roll width. e) Weight (net/gross) 8 60641-1 IEC:2008 Table 1 Classification Pres
