22、opper-catalyzed oxidative degradation of polyolefin insulated conductors 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 inte

23、rnational 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 Reports, Publicly Available Specifications (PAS) and Guides (hereaft

24、er 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 and non-governmental organizations liaising with the IEC also partici

25、pate 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 agreements of IEC on technical matters express, as nearly as possible, an i

26、nternational 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 are accepted by IEC National Committees in that sense. While all re

27、asonable 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 international uniformity, IEC National Committees undertake to apply

28、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 in the latter. 5) IEC itself does not provide any attestation of con

29、formity. 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 users should ensure that they have the latest edition of this public

30、ation. 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 other damage of any nature whatsoever, whether direct or indirect, o

31、r 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 publication. Use of the referenced publications is indispensable for the corre

32、ct 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 patent rights. International Standard IEC 60811-410 has been prepared

33、by IEC technical committee 20: Electric cables. This Part 410 of IEC 60811 cancels and replaces Annex B of IEC 60811-4-2:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition

34、, but see the Foreword to IEC 60811-100:2012. 4 60811-410 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1294/FDIS 20/1343/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the abov

35、e 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 under the general title Electric and optical fibre cables Test methods for

36、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“ in the data related to the specific publication. At this date, the publi

37、cation will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-410 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

38、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 and have been developed and used over many years principally for the mater

39、ials 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 60811-410 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIAL

40、S Part 410: Miscellaneous tests Test method for copper-catalyzed oxidative degradation of polyolefin insulated conductors 1 Scope This Part 410 of IEC 60811 gives the procedure for copper-catalyzed oxidative degradation of a polyolefin, which is typically used for insulation in communication cables.

41、 Full test conditions, such as temperature, duration, etc. and full test requirements are not specified in this standard; it is intended that they should be specified by the standard dealing with the relevant type of cable. 2 Normative references The following documents, in whole or in part, are nor

42、matively 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 m

43、ethods 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 The need for a manufacturer to monitor his cable production to ensure that it has adequate resistance to ox

44、idation is well established. The Oxidation Induction Time (OIT) test has been found suitable for monitoring both raw materials and cables for compliance with this requirement, once suitable materials have been selected. The OIT test is not suitable for the selection of materials. For this purpose, l

45、ong-term thermal ageing tests are preferred. 4.2 Apparatus For the purposes of this test, the different equipment used is as follows: a) A differential thermal analyser or differential scanning calorimeter, capable of heating at rates of up to at least (20 1) K/min and maintaining the test temperatu

46、re isothermally within 0,2 K and of automatic recording of differences in temperature (or differences in heat transfer) between the sample and a reference material to the required sensitivity and precision. b) A recorder capable of displaying heat flow or temperature difference on the Y-axis, and ti

47、me on the X-axis. The time base shall be accurate to 1 % and be readable to 0,1 min. c) A gas-selector switch and regulators for high-purity nitrogen and oxygen. 60811-410 IEC:2012 7 d) An analytical balance capable of weighing 30 g, and readable and repeatable to 0,1 mg. e) Test pieces holders: alu

48、minium holders, each of approximately 6 mm to 7 mm in diameter, or of similar dimensions as supplied by the manufacturer of the instrument. 4.3 Sample and test pieces preparation From a sample of the cable, prepare an appropriate number, e.g. four test pieces of different colours, of approximately 4

49、 mm length containing the core. The test pieces shall be cut from an insulated core to yield 3 mg to 5 mg of insulating material. Insert one test piece in an aluminium holder. 4.4 Test procedure Before carrying out a test series, the instrument shall be calibrated and prepared as described in Annex A. Open valves on both the nitrogen and oxygen gas cylinders. Place the gas selector switch
