20、COMMISSION _ ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 503: Mechanical tests Shrinkage test for sheaths FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical commit
21、tees (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 Specifications, Technical
22、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. International, governmental a
23、nd 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 formal decisions or agreeme
24、nts 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 international use and
25、 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) In order to promote i
26、nternational 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 be clearly indicated
27、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 not responsible for any services carried out by independent certification bodies. 6) All
28、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, property damage or
29、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 cited in this publicatio
30、n. 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 identifying any or all such pa
31、tent rights. International Standard IEC 60811-503 has been prepared by IEC technical committee 20: Electrical cables. This Part 503 of IEC 60811 cancels and replaces Clause 11 of IEC 60811-1-3:1993, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. Ther
32、e are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100: 2012. 4 60811-503 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1299/FDIS 20/1348/RVD Full information on the voting for the approval of
33、 this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part of IEC 60811 shall be used in conjunction with IEC 60811-100. A list of all the parts in the IEC 60811 series, published un
34、der the general title Electric and optical fibre cables Test methods for non-metallic materials, 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“
35、 in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-503 IEC:2012 5 INTRODUCTION The IEC 60811 series specifies the test methods to be used for testing non-metallic materials of all types of c
36、ables. These test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1 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 a
37、nd have been developed and used over many years principally for the materials in all energy cables. They have also been widely accepted and used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications. 6 60811-503 IEC:2012
38、 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 503: Mechanical tests Shrinkage test for sheaths 1 Scope This Part 503 of IEC 60811 gives the test method for the shrinkage for sheaths. 2 Normative references The following documents, in whole or in part, are normativel
39、y referenced in 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
40、for non-metallic 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. 4.2 Test equipment The test equipment shal
41、l be as follows: an air oven, electrically heated, capable of maintaining the test temperature; a measuring tape with a scale division of 1 mm. 4.3 Sampling The cable to be tested shall be stored for at least 24 h at room temperature before the test. One test piece of complete cable (500 5) mm in le
42、ngth shall be taken at least 2 m away from the end of the cable length. 4.4 Preparation of test pieces The initial length of the sheath (L1) shall be determined, immediately after cutting, as the mean value of two measurements. These shall be made longitudinally and parallel to the cable sample axis
43、 between diametrically opposite marks on the ends of the sample. If the sample is bent, these measurements shall be taken on the inside and outside of the bend. 60811-503 IEC:2012 7 4.5 Test procedure The test piece shall be supported horizontally in the air oven preheated to the temperature specifi
44、ed in the cable standard. The test piece should remain in the oven for the time specified in the cable standard. The test piece shall then be removed from the oven and allowed to cool in air to room tempe-rature. This thermal cycle shall be carried out five times. After cooling to room temperature,
45、the final length of the sheath (L2) shall be determined as described in 4.4. 4.6 Expression of results The percentage shrinkage L is the difference between the distances between the marks before the heat treatment (L1) and after the heating and cooling (L2), recorded as a percentage of the distance
46、between the marks before the treatment: L = %100121LLL5 Test report The test report shall be in accordance with that given in IEC 60811-100. 8 60811-503 IEC:2012 Bibliography IEC 60811-1-3:1993, Insulating and sheathing materials of electric cables - Common test methods Part 1: General application v
