22、easurement of insulation thickness 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 question

23、s 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)”

24、). 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 collabor

25、ates 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 on t

26、he 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 th

27、at 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 the

28、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 bod

29、ies 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 to

30、 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) and

31、 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. 9)

32、 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 60811-201 has been prepared by IEC technical committee 20: Electri

34、11-201 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1280/FDIS 20/1329/RVD 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 accor

35、dance with the ISO/IEC Directives, Part 2. This part of IEC 60811 shall be read in conjunction with IEC 60811-100. A list of all the parts in the IEC 60811 series, published under the general title Electric and optical fibre cables Test methods for non-metallic materials, can be found on the IEC web

36、site. 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 publication will be reconfirmed, withdrawn, replaced by

37、a revised edition, or amended. 60811-201 IEC:2012 5 INTRODUCTION The IEC 60811 series specifies the test methods to be used for testing non-metallic materials of all types of cables. These test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1

38、Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables. NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over many years principally for the materials in all energy cables. They have also been wide

39、ly accepted and used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications. 6 60811-201 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 201: General tests Measurement of insulation

40、 thickness 1 Scope This Part 201 of IEC 60811 gives the methods for measuring the insulation thicknesses which apply to the most common types of insulating compounds (cross-linked, PVC, PE, PP, etc.). 2 Normative references The following documents, in whole or in part, are normatively referenced in

41、this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60811-100:2012, Electric and optical fibre cables Test methods for non-metallic

42、 materials Part 100: General 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60811-100 apply. 4 Test method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100. Unless otherwise specified, tests shall be carried out at

43、room temperature. Measurement of insulation thickness may be required as an individual test, or as a step in the procedure for carrying out other tests, such as the determination of mechanical properties. In each case, the method of selecting samples shall be in accordance with the relevant cable st

44、andard. 4.2 Measuring equipment A measuring microscope or a profile projector of at least 10 x magnification or an optical digital image analyser shall be used. These two types of equipment shall allow a reading of 0,01 mm and an estimated reading to three decimal places when measuring insulation wi

45、th a specified thickness less than 0,5 mm. In case of doubt, the measuring microscope shall be taken as the reference method. 60811-201 IEC:2012 7 4.3 Sample and test pieces preparation Any covering shall be removed from the insulation, and the conductor(s), together with separator (if any) shall be

46、 withdrawn, care being taken to avoid damage to the insulation. Semi-conducting inner and/or outer layers, if bonded to the insulation, shall not be removed. Each test piece shall consist of a thin slice of insulation. The slice shall be cut with a suitable device along a plane perpendicular to the

47、longitudinal axis of the conductor. The cores of non-sheathed flat cables shall not be separated. If the insulation carries an indented marking, thus giving rise to a local reduction in thickness, the test piece shall be taken so as to include such marking. 4.4 Measuring procedure The test piece sha

48、ll be placed under the measuring equipment with the plane of the cut perpendicular to the optical axis. a) When the inner profile of the test piece is of circular form, six measurements shall be made radially, each approximately 60, as shown in Figure 1. For sector-shaped cores, six measurements sha

49、ll be made as shown in Figure 2. b) When the insulation is taken from a stranded conductor, six measurements shall be made radially as shown in Figures 3 and 4. c) When the outer profile shows unevenness, the measurement shall be carried out as shown in Figure 5. d) When there are unremovable screening layers under and/or over the insulation, they shall be excluded from the measurements.
