21、 IEC:2012 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 506: Mechanical tests Impact test at low temperature for insulations and sheaths FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organ
22、ization 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 other activities,
23、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 the subject dealt w
24、ith 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 conditions determined by
25、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 National Committees. 3)
26、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 in which they are
27、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 Publication and the
28、 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 is not responsibl
29、e 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 technical committe
30、es 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 IEC Publications.
31、 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 subject of patent r
32、ights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60811-506 has been prepared by IEC technical committee 20: Electric cables. This Part 506 of IEC 60811 cancels and replaces 8.5 of IEC 60811-1-4:1985, which is withdrawn. Full details o
33、f 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 60811-100:2012. 4 60811-506 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1302/F
34、DIS 20/1351/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 conjunction with IEC 60811-
35、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 unchanged until the stabilit
36、y 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 a revised edition, or amended. 60811-506 IEC:2012 5 INTRODUCTION The IEC 60811 series specifies the test metho
37、ds 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 or taping within cables.
38、 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, communication and control cables an
39、d cables for ships and offshore applications. 6 60811-506 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 506: Mechanical tests Impact test at low temperature for insulations and sheaths 1 Scope This Part 506 of IEC 60811 gives the procedure for performing imp
40、act tests at low temperature on extruded insulations and sheaths. 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 references,
41、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 terms and definitions given in IEC 60811-10
42、0 apply. 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 of the insulating or sheathing compounds Tests shall be carried out at the temperature specified in th
43、e relevant cable standard. This cold impact test is intended for sheathed cables of any type, irrespective of the type of insulation of the cores, and for the insulation of wires, cables and flat cables without sheath if required by the relevant cable standard. The insulation of sheathed cables is n
44、ot subjected directly to the cold impact test. 4.2 Sampling and preparation of the test pieces Three pieces of complete cable each having a length at least five times the diameter of the cable with a minimum of 150 mm, shall be taken. All covering external to the component shall be removed. 4.3 Appa
45、ratus The apparatus to be used for this test is represented in Figure 1, with explanations. 60811-506 IEC:2012 7 The apparatus shall be placed on a pad of sponge rubber about 40 mm thick and held in a suitable low temperature cabinet before and during the test. 4.4 Test conditions The test temperatu
46、re shall be as specified for the type of compound in the relevant cable standard. For power cables for fixed installations, the mass of the hammer for testing the samples shall not be less than the values as given in Table 1.
