INTRODUCTION
IEC 60092 (all parts) concerns electrical installations in sea-going ships, and fixed and mobile
offshore units, incorporating good practice and co-ordinating as far as possible existing rules.
These standards form a code of practical interpretation and amplification of the requirements
of the International Convention on Safety of Life at Sea, a guide for future regulations which
may be prepared and a statement of practice for use by shipowners, shipbuilders, mobile and
fixed offshore units owners and builders and appropriate organisations.
Cables selected for installation on board ships and on offshore installations are usually installed
and are expected to operate in much harsher environments than equivalent land based types.
The risk of mechanical abuse during installation, physical dislocation due to tension and
bending allied with extremes of temperature are examples of the conditions to which these
cables may be subject. If faults occur unlike onshore installations, trained experienced
technicians may not always be readily available to affect a repair or replacement.

ELECTRICAL INSTALLATIONS IN SHIPS –
Part 370: Guidance on the selection of cables for telecommunication
and data transfer including radio-frequency cables
1 Scope
This part of IEC 60092, which is a Technical Report, gives guidance and lays down the basic
recommendations for the selection and installation of shipboard and offshore unit cables
intended for electrical systems used in both essential and non-essential analogue or digital
signal communication, transmission and control networks, including types suitable for high-

IEC 60092-350, Electrical installations in ships – Part 350: General construction and test
methods of power, control and instrumentation cables for shipboard and offshore applications
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60092-350 apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:

4 Selection of cables
Cables with physical and electrical characteristics in accordance with IEC 60092 (all parts) are
recommended for use in the marine environment.
Cables constructed in accordance with the following standards are acceptable provided that
due consideration has been given to their use in a marine environment: IEC 60189-1,
IEC 60189-2, IEC 60189-3, and IEC 60096-0-1.
5 Fundamental considerations
The choice of materials and cable construction should be suitable for the intended application
and installation of the cable.
The high level of electrical performance associated with many modern cables is only achieved
by the accurate, consistent positioning of the various components within the cable. Careless or
excess tension, compression or bending can alter this relationship. This may then have
significant detrimental effects upon the fundamental performance of the cable at high data rates.
Similarly, these high levels of electrical performance can usually only be achieved by the use
of polymers and insulation systems that may not have the same reaction to fire characteristics
as the more traditional materials used in other marine cables. In recognition of this, careful
consideration should be given to the method of installation to select that most appropriate to
the particular application (see also Clause 8).
6 Constructional considerations
6.1 Selection of conductor
Only circular copper conductors, either plain or metal coated, or copper covered steel, are
recommended for use in a marine environment. Stranded conductors are recommended for
general use. Where the applicable product standard specifies solid conductors, consideration
should be given to the possible effects of vibration (due to the movement of the ship or
installation) or movement (due to motion of the ship or installation).
The properties of copper conductors should be in accordance with IEC 60228. Joints in solid
conductors or complete stranded conductors are not permitted; however, joints in individual
strands are allowed.
When cables are subject to continuous flexing, the advice of the manufacture should be sought.
6.2 Selection of insulation
The range of materials for use as conductor insulation should, where possible, be selected from
those listed in IEC 60092-360 or as given in IEC 60096-0-1 and IEC 61156-5-1. For cables
operating at the higher frequencies, the insulation may be solid, cellular or a foam skin
composite. The rated operating temperature of the insulating material should be at least 10 °C
higher than the maximum ambient temperature likely to exist, or to be produced, in the space
where the cable is installed.
The insulation should be continuous, having a thickness as uniform as possible. The insulation
should be applied to fit closely to the conductor.
6.3 Cable elements
The cores within each pair, triple, or quad should be clearly identified by colour or number as
given in the applicable cable standard. The identification used should be durable and legible.
The choice of the maximum average length of lay in the finished cable should be selected with
respect to the specified crosstalk requirements, handling performance and the pair or quad
integrity.
– 8 – IEC TR 60092-370:2019 IEC 2019
6.4 Selection of screen, core screen or shield
If a screen is required, it may consist of the following:
a) a metallic laminated tape bonded to polyester and a drain wire in direct contact with the
metallic side of the tape;
a) plain or metal coated copper braid;
b) a metallic laminated tape bonded to polyester and a drain wire in direct contact with the
metallic side of the tape with a plain or metal coated copper braid.
The construction of the screen, core screen or shield should be as listed in IEC 60092-350 or
the applicable cable standard. Care should be taken when putting dissimilar metals in contact
with each other. Coatings or other methods of protection may be necessary to prevent galvanic
interaction often encountered in the marine environment.
6.5 Selection of outer sheath
The range of materials for use as protective sheath should, where possible, be selected from
those listed in IEC 60092-360, which have been proven by experience to be suitable for use in
the marine environment. Materials listed in IEC 60096-0-1 and IEC 61156-1 may also be
considered; the material chosen should meet the requirements of this document.
The material selected should be compatible with the cable components with which it is in contact
and compatible with the intended environment and operating temperature of the cable.
In instances where the construction of a cable does not conform with a standard from
IEC 60092 (all parts), it should be ensured that the material used as the protective sheath has
adequate mechanical strength in respect of the mechanical hazards to which it may be
subjected during installation and service. The potential for corrosion, of underlying layers,
encountered in the marine environment should also be considered. Attention is drawn to the list
of permitted protective coverings given in IEC 60092-350.
Due consideration should be given to fluid resistance for cables installed where water
condensation or harmful vapours (including oil vapour) may be present. In this instance, the
cables should meet the appropriate fluid resistance requirements of IEC 60092-360.
Also, consideration should be given to the fire performance characteristics given in Clause 10.
The minimum thickness of sheath considered as being acceptable for cables for installation on
board a ship or offshore installation is 0,7 mm.
6.6 Selection of metallic sheath (covering), braid or armour
The construction of the metal braid armour should be in accordance with IEC 60092-350. The
type of metal braid armour should be carefully selected by the user in respect of not only the
mechanical hazards but also t

recommended for use in a marine environment. Stranded conductors are recommended for
general use. Where the applicable product standard specifies solid conductors, consideration
should be given to the possible effects of vibration (due to the movement of the ship or
installation) or movement (due to motion of the ship or installation).
The properties of copper conductors should be in accordance with IEC 60228. Joints in solid
conductors or complete stranded conductors are not permitted; however, joints in individual
strands are allowed.
NOTE When cables are subject to continuous flexing, the advice of the manufacture should be
sought.
6.2 Selection of insulation
The range of materials for use as conductor insulation should, where possible, be selected from
those listed in IEC 60092-351 IEC 60092-360 or as given in IEC 60096-0-1 and IEC 61156-5-
1. For cables operating at the higher frequencies, the insulation may be solid, cellular or a foam
skin composite. The rated operating temperature of the insulating material should be at least
10 °C higher than the maximum ambient temperature likely to exist, or to be produced, in the
space where the cable is installed.
The insulation should be continuous, having a thickness as uniform as possible. The insulation
should be applied to fit closely to the conductor.
NOTE The user should carefully select the insulation material regarding its electrical characteristics and intended
use in the marine environment.
6.3 Cable elements
The cores within each pair, triple, or quad should be clearly identified by colour or number as
given in the applicable cable standard. The identification used should be durable and legible.
The choice of the maximum average length of lay in the finished cable should be selected with
respect to the specified crosstalk requirements, handling performance and the pair or quad
integrity.
– 8 – IEC TR 60092-370:2019 RLV IEC 2019
6.4 Selection of screen, core screen or shield
If a screen is required, it may consist of the following:
a) a metallic laminated tape bonded to polyester and a drain wire in direct contact with the
metallic side of the tape;
b) plain or metal coated copper braid;
c) a metallic laminated tape bonded to polyester and a drain wire in direct contact with the
metallic side of the tape with a plain or metal coated copper braid.
The construction of the screen, core screen or shield should be as listed in IEC 60092-350 or
the applicable cable standard. Care should be taken when putting dissimilar metals in contact
with each other. Coatings or other methods of protection may be necessary to prevent galvanic
interaction often encountered in the saliferous marine environment.
NOTE The type of screening should be carefully selected by the user in respect of not only the type of disturbance,
electrostatic or electro-magnetic, but also the mechanical hazards, and potential for corrosion, encountered in the
marine environment.
6.5 Selection of outer protection sheath
The range of materials for use as protective sheath should, where possible, be selected from
those listed in IEC 60092-359 IEC 60092-360, which have been proven by experience to be
suitable for use in the marine environment. Materials listed in IEC 60096-0-1 and IEC 61156-1
may also be considered; the material chosen should meet the requirements of this document.
The material selected should be compatible with the cable components with which it is in contact
and compatible with the intended environment and operating temperature of the cable.
In instances where the construction of a cable does not conform with a standard from
IEC 60092 (all parts), it should be ensured that the material used as the protective sheath has
adequate mechanical strength in respect of the mechanical hazards to which it may be
subjected during installation and service. The potential for corrosion, of underlying layers,
encountered in the marine environment should also be considered. Attention is drawn to the list
of permitted protective coverings given in IEC 60092-350.
Due consideration should be given to fluid resistance for cables installed where water
condensation or harmful vapours (including oil vapour) may be present. In this instance, the
cables should meet the appropriate fluid resistance requirements of Annex D of IEC 61892-4
IEC 60092-360.
NOTE Not all materials in IEC 60092-359 meet the fluid resistance requirement.
Also, consideration should be given to the fire performance characteristics given in Clause 10.
The minimum thickness of sheath considered as being acceptable for cables for installation on
board a ship or offshore installation is 0,7 mm.
6.6 Selection of metallic sheath (covering), braid or armour
The construction of the metal braid armour should be in accordance with IEC 60092-350. The
type of metal braid armour should be carefully selected by the user in respect of not only the
mechanical hazards but also the potential for corrosion encountered in the marine environment.
Care should be taken when putting dissimilar metals in contact with each other. Coatings or
other methods of protection may be necessary to prevent galvanic interaction often encountered
in the saliferous marine environment.
7 Marking
Cables should be provided with a continuous indication of origin (manufacturers name or trade
mark), by one of the following methods:
a) printing, indenting or embossing on the outer sheath;
b) a printed tape within the cable;
c) the inclusion of identification threads within the cable;
d) printing on the insulation of at least one core.
The marking should be durable and legible.
The spacings and dimensions of the indication of origin should be as given in the applicable
product standard.
8 Guidance on the selection of appropriate tests
Unless otherwise specified in the applicable product standard, tests should be made at an
ambient temperature of (20 ± 15) °C.
This document defines, by the frequency range in the intended application, seven classes of
cable (Table 1) and, in Annex A, gives guidance in the selection of the appropriate tests to be
applied, related to each class.
Table 1 – Classification of cables by frequency range
Cable type Frequency range
1 f max < 100 kHz
100 kHz < f > 1 MHz
1 MHz < f > 16 MHz
4 16 MHz < f > 125 MHz
5 125 MHz < f > 250 MHz
250 MHz < f > 600 MHz
7 250 Hz < f > 1 000 MHz
NOTE All cables are backwards compatible.
9 Guide to use
9.1 Introduction Purpose
The aim of Clause 9 is to inform users of characteristics and limitations of electric cables and
thereby to minimise misuse.
It is assumed that the design of installation and the specification, purchase and installation of
cables in accordance with this document is entrusted to suitable skilled and competent people.
In case of doubt as to the suitability of cables covered by this document for a particular use,
further specific information should be obtained from the manufacturer.
– 10 – IEC TR 60092-370:2019 RLV IEC 2019
9.2 General
All cables should be stored in a suitable place until required. Consideration should be given to
security and environmental conditions.
Any protective packaging should not be removed until the cable is to be installed.
The ends of cables should always remain sealed during storage and installation to prevent the
ingress of water and other contaminants.
9.3 Voltage rating
9.3.1 Data and telecommunication cables
All cables covered by this document should be subject to electrical tests applicable to their
maximum rated voltage. Recommended maximum rated voltages for data and instrumentation
telecommunication cables are:
• 30 V AC;
• 60 V AC;
• 250 V AC.
The rated voltage of any cable should not be lower than the nominal voltage of the circuit for
which it is used.
NOTE These cables are not intended to be used for power supply.
9.3.2 High-frequency radio communications cables
The voltage rating of the cable should not be lower than the nominal voltage of the radio
communication system in which it will be used.
9.4 Current ratings
The cables covered by this document are only recommended for use in circuits carrying
analogue and digital signals.
Where high power co-axial feeder cables are to be used, advice from the cable manufacturer
should be sought.
NOTE These cables are not intended to be used for power supply.
9.5 Thermal considerations
It is recommended that the rated operating temperature of the cable selected shall be at least
10 °C K higher than the maximum ambient temperature likely to exist, or to be produced, in the
space where the cable is installed.
These cables should not normally be run in groups or bundles containing power cables
operating at or near their maximum operating temperature. Where this is unavoidable, then the
operating temperature should be based upon the lowest maximum operating temperature of any
cable in the group or bundle.
All insulation and sheathing materials used for cables become progressively stiffer as their
temperature is lowered below the normal ambient temperature to the point where they become
brittle. This should be carefully considered when comparing the minimum operating temperature
of the cable with the intended environment and application.
The cable should be acclimatised at the recommended environmental conditions before
installation.
9.6 Size of conductors
The selection of the size of each conductor should not be based upon the attenuation or the
electrical characteristics of the circuit alone. Account should be taken of the mechanical
strength, the method, as well as the route, upon which the cable is to be installed. The cable
should be of sufficient size as to mitigate mechanical damage, and impairment of its electrical
integrity and characteristics, during installation and subsequent operation in the conditions
encountered in the marine environment.
9.7 Radius of bend
The internal radius of bend for the installation of all cables should be chosen according to the
type of cable as recommended by the manufacturer such that the electrical integrity and
characteristics of the cable are not impaired due to disassociation of components within the
cable.
The minimum bending radius used should never be less than what is recommended by the
manufacturer.
Particular care should be taken when dressing cable, inserting cable into conduit, bending
around corners in conduit or at the transition from vertical to horizontal tray to ensure that the
cable is never bent below the recommended minimum bending radius.
NOTE Cable runs should be selected to keep the number of bends to a minimum.
Cables with class 5 conductors are not intended for flexible applications.
9.8 Tensile stress
In assessing the risk of mechanical damage to cables, account should be taken of any
mechanical strains likely to be imposed during the normal process of installation of cables.
Cables should be so installed that the tensile stress applied to them, either by reason of their
own weight or for any other reason, is minimised. Excessive tension can cause disassociation
of components within the cable resulting in the impairment of the electrical integrity and
characteristics of the cable. These precautions are particularly important for cables of small
cross-section and for cables on vertical runs or in vertical conduit or ducting.
The distances between supports should be as recommended by the cable manufacturer and
chosen to avoid excessive tension due to sagging in the cable. Careful consideration should be
given to cable runs along weather decks, when the cable run is arranged so that the cables can
be subjected to forces by water washing over the deck.
The mechanical strength of conductors should be sufficient for the method of installation and
working conditions.
9.9 Compression
Fixings and supports used should have a surface area sufficiently large and be shaped so that
the cables remain tight without their coverings being damaged. Care should be exercised to
ensure that the forces applied by these fixings do not cause impairment of the electrical integrity
and characteristics of the cable due to disassociation of components within the cable.
Installations should be such that tensions in cables and cinching of bundles shall be minimized.
The cable sheath should not be deformed.
– 12 – IEC TR 60092-370:2019 RLV IEC 2019
Where individual stuffing glands or boxes containing several cables are used to penetrate
bulkheads or decks, care needs to be taken to avoid excessive clamping or compressive forces
causing impairment of the electrical integrity and characteristics of the cable due to
disassociation of components within the cable. Installations shall be such that tensions in cables
and cinching of bundles are minimized. The cable sheath should not be deformed.
9.10 Mechanical damage
To avoid the risk of mechanical damage, data, telecommunication and high-frequency radio
communications cables should not normally be installed within the same conduit or trunking as
cables of other services. Where this is impractical, they should be separated by a strong, rigid
and continuous partition.
9.11 Electromagnetic interference
In order to avoid as much as possible the effects of unwanted electromagnetic interference,
attention should be given to IEC 60533. This might be of particular importance for the
installation of cables in vicinity of radio equipment and for the installation of cables belonging
to sensitive electronic control and monitoring systems.
Careful consideration shall be given to the earthing of metal coverings of cables to ensure that
safety of personnel and equipment is achieved as well as meeting the requirements of the
electrical characteristics of the circuit.
As general guidance, earthing of the metal covering at one end only will be effective against
static electricity, spikes and discharges. However, the cable may then act as an antenna.
Earthing of the metal covering at both ends will be effective against magnetic fields. However,
ground loops or circulating currents may be set up in the cable.
The metal covering of cables may be earthed by means of glands intended for the purpose and
so designed as to ensure an effective earth connection.
The electrical continuity of all metal coverings throughout the length of the cables, particularly
at joints and tapings, should be ensured.
Metal casings, pipes and conduits or trunking should be effectively earthed.
9.12 Terminations
Only approved proprietary terminations should be used when terminating essential, and non-
essential, analogue or digital signal, communication, transmission and control cables. The
length of sheath and protection removed should be minimised to prevent disassociation of the
components within the cable.
9.13 Joints
Cable runs should not normally include joints. Where the use of joints is unavoidable, the advice
of the cable manufacturer should be sought.
10 Performance in a fire
The high-level signal transmission characteristics achieved by some types of cables rely upon
the use of polymers and insulation systems with reaction to fire properties that may not match
those of the more traditional materials listed in IEC 60092-351 and IEC 60092-359 IEC 60092-
360, especially where cables are installed in large bunches. This problem has been recognised
and there are now several possible solutions to it. Careful consideration should be given to
each installation to select the most appropriate method. Examples of these solutions relate to
the installation methods employed as well as material types. Typical methods are:
a) Installation techniques:
• the use of additional fire stops;
• additional segregation.
b) General housekeeping:
• removal of redundant obsolete cables.
c) Materials and related matters:
• the use of intumescent coatings.
NOTE 1 The above examples are neither exhaustive, nor show any particular order of preference.
NOTE 2 Care should be taken with the use of methods in c) as some materials, if they burn,
release significant quantities of dense smoke, which may obscure an escape route, and/or
gases that may can be corrosive to equipment or harmful to personnel.
NOTE 32 For the use of fire stops, see Annex C of IEC 60092-352:2005.
Not withstanding the foregoing, all cables should meet the requirements for flame as given in:
– IEC 60332-1-1 and IEC 60332-1-2, and
– IEC 60332-3-25.
Unless otherwise specified in the individual product standard, The cables should be tested in a
touching configuration.
NOTE 43 If a cable or an insulated wire meets the requirements of IEC 60332-12 IEC 60332-1-2, it cannot be
assumed that a bunch of similar cables or insulated wires will behave in a similar manner. The flame spread
performance of bunched cables is assessed by the requirements of IEC 60332-3-25. This performance requirement
(i.e. for cables mounted vertically in a touching formation) has been chosen to best reflect the installation conditions
generally observed on board ships. Experience has shown that the test for the flame spread of cables installed
vertically is adequate for horizontal installations, all other parameters being generally the same.
NOTE 5 Further information is given in IEC 60332-3-25.
For systems intended to maintain electrical circuit integrity under fire conditions, the selection
of cable should only be made after consultation with the appropriate approval and regulatory
authority.
Requirements for smoke emission and acid gas evolution should be considered where
applicable and when the cables are evaluated in accordance with the following test methods
and should meet the requirements specified in the individual product standard: IEC 61034-2,
IEC 60754-1 and IEC 60754-2 the test methods cited in the IEC 60092-350.
