23、TIONAL ELECTROTECHNICAL COMMISSION _ ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 501: Mechanical tests Tests for determining the mechanical properties of insulating and sheathing compounds FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwi
24、de 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 other acti
25、vities, 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
26、 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 conditions determ
27、ined 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 National Committ
28、ees. 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 in which t
29、hey 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 Publication
30、 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 is not re
31、sponsible 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
32、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 IEC Publi
33、cations. 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
34、patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60811-501 has been prepared by IEC technical committee 20: Electric cables. This Part 501 of IEC 60811 cancels and replaces Clause 9 of IEC 60811-1-1:1993, which is withdrawn. F
35、ull details of the replacements are shown in Annex A of IEC 60811-100:2012. There is one significant technical change with respect to the previous edition: the requirements for the (minimum) thickness of dumb-bell test pieces have changed. See also the Foreword to IEC 60811-100. 4 60811-501 IEC:2012
36、 The text of this standard is based on the following documents: FDIS Report on voting 20/1297/FDIS 20/1346/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
37、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 found on the IEC website. The commi
38、ttee 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, withdrawn, replaced by a revised editi
39、on, or amended. 60811-501 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 materials. NOTE 1 Non-metallic ma
40、terials 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 have also been widely accepted and
41、 used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications. 6 60811-501 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 501: Mechanical tests Tests for determining the mechanical
42、properties of insulating and sheathing compounds 1 Scope This Part 501 of IEC 60811 gives the procedure for determining the mechanical properties, which typically applies to cross-linked and thermoplastic compounds used for insulating and sheathing materials. 2 Normative references The following doc
