IEC 60092-350-2020 pdf free.Electrical installations in ships – Part 350: General construction and test methods of power, control and instrumentation cables for shipboard and offshore applications.
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 conductors 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 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 standards, for example IEC 60227 (all parts) and lEO 60245 (all parts), and their uses are restricted to those situations which do not directly involve 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.

4.1.3 Cable marking
4.1.3.1 Indication of origin
Cables shall be provided with a continuous indication of origin (manufacturer’s name and/or
trade mark) by one or more 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 shall be legible.
Spacing and dimensions of the indication of origin shall be as given in the applicable product standard.
Conformity shall be checked by visual examination, and the durability of the print, where applicable, shall be in accordance with the test given in 8.20.
NOTE National or regulatory authorities or approval bodies might request the method of marking according to
their applicable rules.
4.1.3.2 Rated voltage and cable construction
When specified In the applicable product standard, the rated voltage (LT0/L!) and the construction (number of cores and cross-sectional area of the conductors) shall be printed, indented or embossed on the outer sheath.
The marking shall be legible.
Spacing and dimensions shall be as given in the applicable product standard.
Conformity shall be checked by visual examination, and the durability of the print where applicable shall be in accordance with the test as given in 8.20.
4.1.3.3 Optional cable designationlexternal markings
When agreed between the manufacturer and purchaser, cables may, in addition, be marked with a code designation that signifies the type of insulation/screening/armouring and sheathing materials used in their construction.
The marking shall be by embossing, indenting or printing on the outer sheath.
The marking shall be legible.
Spacing and dimensions shall be as given in the applicable product standard.
Conformity shall be checked by visual examination, and the durability of the print where applicable shall be in accordance with the test as given in 8.20.
4.1.4 Core identification
All cores shall be clearly identified.IEC 60092-350 pdf free download.
