14、ods of power, control and instrumentation 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

15、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, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) a

16、nd Guides (hereafter 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 th

17、e IEC also participate 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

18、 as possible, an international 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 s

19、ense. 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 used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees u

20、ndertake to apply 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 provides no marking procedur

21、e to indicate its approval and cannot 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

22、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) and expenses arising out of the publication, use of, or

23、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. 9) Attention is drawn to the possibility that some of t

24、he 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 60092-350 has been prepared by subcommittee 18A: Cables and cable installations, of IEC technical committee 18: Electri

25、cal installations of ships and of mobile 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 ins

26、ulating compounds contained in IEC 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 application

27、s, the provision to allow the design 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 standar

28、d is based on the following documents: 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

29、2. The list of all the parts of the 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 unde
