21、ELECTROTECHNICAL COMMISSION _ ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 510: Mechanical tests Methods specific to polyethylene and polypropylene compounds Wrapping test after thermal ageing in air FOREWORD 1) The International Electrotechnical Commission (IEC) is
22、 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 fields. To this end and in addition to
23、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 IEC National Committee interested in t
24、he 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 Standardization (ISO) in accordance with conditi
25、ons 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 representation from all interested IEC Nation
26、al 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 cannot be held responsible for the way
27、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 publications. Any divergence between any IEC P
28、ublication 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
29、 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 IEC or its directors, employees, servants or agents including individual experts and members of its
30、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 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other
31、 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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the s
32、ubject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60811-510 has been prepared by IEC technical committee 20: Electric cables. This Part 510 of IEC 60811 cancels and replaces Clause 10 of IEC 60811-4-2:2004, which is w

There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100: 2012. 4 60811-510 IEC:2012 The text of this standard is based on the following documents: FDIS R
34、eport on voting 20/1306/FDIS 20/1355/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 accordance with the ISO/IEC Directives, Part 2. This part of IEC 60811 shall be used in co
35、njunction 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 website. The committee has decided that the contents of this publication will remain unc

At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-510 IEC:2012 5 INTRODUCTION The IEC 60811 series
37、 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 Non-metallic materials are typically used for insulating, sheathing, bedding, filling
38、 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 widely accepted and used for other cables, in particular optical fibre cables, communicat
39、ion and control cables and cables for ships and offshore applications. 6 60811-510 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 510: Mechanical tests Methods specific to polyethylene and polypropylene compounds Wrapping test after thermal ageing in air 1 Sc
40、ope This Part 510 of IEC 60811 specifies the test method for a wrapping test after thermal ageing in air. This test method applies specifically to polyolefin insulation in communication cables. This test is intended for polyolefin insulations of unfilled cables and of dry cores for filled cables, wh
41、ere the insulation has a wall thickness of less than or equal to 0,8 mm. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated refer
42、ences, 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 materials Part 100: General 3 Terms and definitions For the purposes of this document, the definitions given in IEC 60811-100 a
43、pply. 4 Test method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100. All the tests shall be carried out not less than 16 h after the extrusion or cross-linking, if any, of the compounds used for insulating or sheathing. 4.2 Apparatus The apparatus consists of the f
44、ollowing parts: a smooth metal mandrel and loading elements; a winding device, preferably with mechanically driven mandrel; an electrically heated cabinet with natural air flow. 4.3 Sampling The test shall be carried out on four test pieces for each length of cable or core to be tested. Take a sampl
45、e 2 m long and cut it into four test pieces of equal length. 60811-510 IEC:2012 7 Carefully remove the coverings and braidings, if any, from the test pieces and any filling compound which may adhere to the cores. Leave the conductor within the insulation. Then straighten the test pieces. 4.4 Ageing
46、procedure The test pieces prepared in accordance with 4.3 shall be suspended vertically for 14 24 h at (100 2) C in the middle of the heating chamber in accordance with 4.2 so that each test piece is at least 20 mm from any other test piece. Not more than 2 % of the chamber volume shall be occupied
47、by the test pieces. Immediately after the ageing period, the test pieces shall be taken out of the chamber and left at ambient temperature, without being exposed to direct sunlight, for at least 16 h. NOTE The ageing time and/or ageing temperature may be increased if required by the relevant cable s
48、pecifications. 4.5 Test procedure 4.5.1 Test pieces according to 4.3 shall be subjected, after ageing in accordance with 4.4, to a winding test at ambient temperature. 4.5.2 The conductor shall be laid bare at one end. A weight shall be applied to the exposed conductor end, exerting a pull of 15 N/m
49、m2 20 % with respect to the conductor cross-section. Ten windings shall be made on the other end of the test piece by means of a winding device in accordance with 4.2 on a metal mandrel at a speed of about 1 revolution per 5 s. The winding diameter shall be 1 to 1,5 times the test piece diameter. Subsequently, the test pieces wound on the mandrel shall be removed
