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 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 “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 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 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 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 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 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 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 attach 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) 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.
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 60092-353 has been prepared by Subcommittee 18A: Electric
cables for ships and mobile and fixed offshore units of IEC Technical Committee 18: Electrical
installations of ships and of mobile and fixed offshore units.
This third edition cancels and replaces the second edition published in 1995 and Amendment 1
(2001). This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Rationalization of the number of insulating and sheathing materials. In particular polyvinyl
chloride based insulation (PVC) and sheath (ST1) have been removed. PVC sheath ST2 is
permitted even though it releases harmful fumes under fire conditions;
b) Modification of construction requirements in line with IEC 60092-350;

60092-353 © IEC:2011 – 5 –
c) Requirements and test methods have been divided in several tables for clarification.
Requirements for enhanced cold properties, oil resistance and resistance to drilling fluids
have been aligned to IEC 60092-350;
d) The new testing methods for fire resistant cables are referenced in the standard.
The text of this standard is based on the following documents:
FDIS Report on voting
18A/316A/FDIS 18A/319/RVD

The specified nominal thickness for a plain metal tape shall be at least 0,1 mm.
5.6.1.4 Braid
The specified nominal thickness for the braiding wires shall be at least 0,2 mm.
5.6.2 Application
The screen, if any, shall be applied over the inner covering in case of a braided or a metal tape
screen (see 5.1.2 and 5.1.3).
5.7 Inner sheath
5.7.1 Material
The inner sheathing compound and its designation shall be one of those given in
IEC 60092-359 except that PVC type ST1 is not permitted.
5.7.2 Application
The application shall be as detailed in IEC 60092-350, 4.7.2.
5.7.3 Thickness of inner sheath
The thickness of the inner sheath is given as a function of the internal diameter of the sheath
under consideration, the fictitious diameter being calculated by the method in IEC 60092-350,
Annexes A and C.
The formula is:
a) for double sheathed unarmoured cable as 5.1.2 (b):
t = 0,025 D + 0,6 mm, with a minimum thickness of 0,8 mm
b) for armoured cable as 5.1.3 b) and c):
t = 0,04 D + 0,8 mm, with a minimum thickness of 1,0 mm for construction 5.1.3 b) and 1,4
mm for construction 5.1.3 c)
where
D is the fictitious diameter under the inner sheath.
The thickness at any point shall satisfy the prescriptions given in 4.7.3 of IEC 60092-350.
5.8 Braid armour
5.8.1 General
In this standard only metal braid armours are specified, the braid wires being of copper, copper
alloy or galvanized steel.
Joints in the braiding wires shall be soldered, twisted or woven-in and the complete braid shall
not be jointed. The braid shall be evenly applied.
The armour may serve as a collective metallic screen (see 5.6).
