MT 6 - TC 18/MT 6

IEC 60092-303:2023 is applicable to all transformers used for power and lighting and, where appropriate, to static convertors, starting transformers, static balancers, earthing transformers, saturable reactors and transductors for use in ships, including single-phase transformers rated higher than 1 kVA, and three-phase transformers rated higher than 5 kVA, unless special requirements are specified. This document applies to transformers with rated voltage up to and including 36 kV.
This fourth edition cancels and replaces the third edition published in 1980 and Amendment 1:1997. This edition includes the following significant technical changes with respect to the previous edition:
- environmental conditions,
- load harmonic currents,
- Transformers for special applications,
- design and construction,
- transformers for essentials services.

IEC 60092-306:2022 is available as IEC 60092-306:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60092-306:2022 applies to luminaires and lighting accessories for use in ships. It applies primarily to luminaires for illumination purposes. This document also applies to lighting accessories associated with the wiring and current consuming appliance of an installation. This document does not apply to portable luminaires, navigation lights, search lights, daylight signalling lamps, signal lights including the relevant control and monitoring equipment and other lights used for navigation in channels, harbours, etc. Annex A provides EMC considerations for system integrators.

IEC 60092-304:2022 specifies special provisions to power electronic converters and systems, using semiconductor elements for use in ships. The conversion may be from AC to DC, from DC to AC, from DC to DC or from AC to AC with a rated output power greater than 1 kW.
This document does not apply to semiconductor converters used in electrical propulsion plant. For semiconductors converters used in electrical propulsion plant, see IEC 60092-501.

IEC 60092-503:2021(E) is applicable to AC supply systems with voltages from 1 kV up to and including 36 kV. The requirements contained in other parts of the IEC 60092 series apply where appropriate, subject to the exceptions stated in the clauses of this document.

IEC 60092-302-2:2019 defines the specific requirements of low voltage marine power switchgear and controlgear assemblies (MPSC-assemblies) as follows:
- stationary assemblies with enclosure for which the rated voltage does not exceed 1 000 V AC or 1500 V DC;
- assemblies intended for use in conjunction with the power generation, distribution and conversion of electric energy, and for the control of electric energy consuming equipment.
This document applies to all assemblies whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity.
The manufacture and/or assembly can be carried out other than by the original manufacturer.
This document does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, which comply with the relevant product standards.
This first edition cancels and replaces the fourth edition of IEC 60092-302 published in 1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) this document has been renumbered to fall in line with IEC 61439 (all parts);
b) this document has been restructured to fall in line with IEC 61439 (all parts);
c) the creepage distances have been modified;
d) the references to non type tested assemblies (NTTA) have been removed;
e) non-applicable tables have been removed;
f) the applicability of IEC 61439 (all parts) annexes have been identified.
g) specific requirements that were detailed in IEC 60092-302:1997, covered under 7.6.101 have partly been moved to 60092-201.

IEC 60092-504:2016 is available as IEC 60092-504:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60092-504:2016 specifies electrical, electronic and programmable equipment intended for automation, control, monitoring, alert, and safety and protection systems for use in ships. This edition includes the following significant technical changes with respect to the previous edition:
a) the part title has been changed, the term "Automation" was added;
b) the contents of the corrigendum of January 2011 have been included;
c) a new subclause 5.1 "General" with general requirements for type testing has been added;
d) Table 1 contents aligned with current version of document IACS Req. 1991/Rev. 5, 2006;
e) the revised IMO Resolution A.1021(26), Code on alerts and indicators:2009 has been taken into account;
f) IMO Resolution MSC.302(87) has been taken into account. As a consequence, the term "alert" has been used where the generic term applies. This concerns, in particular, the text in 8.4 and 9.3;
g) a new subclause 8.2.4: The revised IMO Resolution MSC.145(77), Performance standards for water level detectors on bulk carriers:2003 has been taken into account;
h) subclause 9.1 about fire detection and alarm systems has been completely revised, IMO Resolution MSC.98(73) (FSS Code) with amendment MSC.292(87): 2010 has been taken into account;
i) a new subclause 9.2 "Bilge systems" has been added;
j) the subclauses 9.4 "Automatic control installations for electrical power supply" and 9.5 "Automatic starting installations for electrical motor-driven auxiliaries" have been completely revised;
k) Clause 10 "Computer based systems" has been completely revised;
l) a new subclause 10.3.6 about wireless data communication has been added;
m) a new subclause 10.5 about remote access has been added.
