14、tation cables for shipboard and offshore applications FOREWORD 1) The International Electro-technical Commission (IEC) is a worldwide organization for standardization comprising all national electro-technical committees (IEC National Committees). The object of IEC is to promote international co-oper
15、ation 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 (hereafter referred to as
16、 “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 participate in this prep
17、aration. 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 international cons
18、ensus 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 reasonable efforts
19、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 IEC Publications
20、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 provides no marking procedure to indicate its approval and cann
21、ot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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 me
22、mbers 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) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication
23、 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. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication
24、 may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60092-350 has been prepared by subcommittee 18A: Cables and cable installations, of IEC technical committee 18: Electrical installations of ships and of m
25、obile and fixed offshore units. This third edition cancels and replaces the second edition published in 2001 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the new insulating compounds contained in IEC
26、60092-351; b) the new sheathing compounds contained in IEC 60092-359; c) the publication of IEC 60092-376; d) the inclusion of cables up to 30 kV in the revision of IEC 60092-354; 60092-350 IEC:2008(E) 5 e) for use in a limited number of closely defined applications, the provision to allow the desig
27、n of a single core cable with a single extrusion covering, having a thickness equal to that of both an insulation and sheath; f) new tests for the determination of enhanced cold properties, oil resistance, and resistance to drilling fluids. The text of this standard is based on the following documen
28、ts: FDIS Report on voting 18A/285/FDIS 18A/286/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. The list of all the parts of the
29、 IEC 60092 series, under the general title Electrical installations in ships, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the da
30、ta related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 60092-350 IEC:2008(E) ELECTRICAL INSTALLATIONS IN SHIPS Part 350: General constru
31、ction and test methods of power, control and instrumentation cables for shipboard and offshore applications 1 Scope This part of IEC 60092 provides the general constructional requirements and test methods for use in the manufacture of electric power, control and instrumentation cables with copper co
32、nductors intended for fixed electrical systems at voltages up to and including 18/30(36) kV on board ships and offshore (mobile and fixed) units. The reference to fixed systems includes those that are subjected to vibration (due to the movement of the ship or installation) or movement (due to motion
33、 of the ship or installation) and not to those that are intended for frequent flexing. Cables suitable for frequent or continual flexing use are detailed in other IEC specifications, for example IEC 60227 and IEC 60245, and their uses are restricted to those situations which do not directly involve
34、exposure to a marine environment, for example, portable tools and domestic appliances. The following types of cables are not included: optical fibre; sub-sea and umbilical cables; data and communication cables; coaxial cables. 2 Normative references The following referenced documents are indispensab
