23、 thermoplastic insulations and sheaths 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 ques

24、tions 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

25、(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 participate in this preparation. IEC coll

26、aborates 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

27、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 reasonable efforts are made to ensur

28、e 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 IEC Publications transparently to

29、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 conformity. Independent certification

30、 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 publication. 7) No liability shall attac

31、h 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, or for costs (including legal fees)

32、 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 correct application of this publication

33、. 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 60811-409 has been prepared by IEC technical committee 20: Ele

34、ctric cables. This Part 409 of IEC 60811 cancels and replaces Clause 8 of IEC 60811-3-2:1985, 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, but see the Foreword to IEC 608

35、11-100:2012. 4 60811-409 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1293/FDIS 20/1342/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 bee

36、n 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 non-metallic materials, can be fo

37、und 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 publication will be reconfirmed, withd

38、rawn, replaced by a revised edition, or amended. 60811-409 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

39、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 materials in all energy cables. They h

40、ave 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 60811-409 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 409: Miscellaneous tests L

46、EC 60811 shall be used in conjunction with IEC 60811-100 Unless otherwise specified, all test procedures, except the period in the ageing oven, shall be carried out at room temperature. 4.2 Test equipment The test equipment shall consist of: 60811-409 IEC:2012 7 a) An oven with natural air flow or a

47、ir flow by pressure. The air shall enter the oven in such a way that it flows over the surface of the test pieces and leaves near the top of the oven. The oven shall have not less than 8 and not more than 20 complete air changes per hour at the specified ageing temperature, as described in 4.2.1 of

48、IEC 60811-401:2012. In case of dispute, an oven with natural air circulation shall be used. A rotating fan shall not be used inside the oven. b) An analytical balance with a sensitivity of 0,1 mg. c) Punching dies for dumb-bell test pieces, according to 4.2.3 b) of IEC 60811-501:2012. d) A desiccato

49、r with silica gel or similar material. 4.3 Sample and test pieces preparation If the loss of mass test is combined (see 4.1 d) of IEC 60811-401:2012) with the mechanical test (4.2. of IEC 60811-501: 2012), the test pieces shall be three of those subjected to the ageing in the air oven specified in 4.2.3.1 of IEC 60811-401:2012, one from each core sample.
