Standards Development

Scope

This document contains requirements and guidelines to ensure electromagnetic compatibility on board all types and sizes of ships unless more specific standards are applicable for specific types or sizes of ships. These requirements and guidelines can be applied during the building process but also when maintenance or upgrades are required.

When equipment standards refer to this document, especially the requirements in clause 8 are applicable.

EXAMPLE IEC 60092-306:2022 [3] (maritime luminaires) and IEC 60092-504:2025 [4] (maritime automation, control and instrumentation equipment) refer to this document.

This document includes:

• Assistance in defining the proper EMC requirements at ship, system, sub-assembly and equipment level.

• Assistance in the delegation of EMC related tasks.

• Tests and measurements to evaluate the EMC performance at ship and system level.

• Emission and immunity requirements for equipment developed for a maritime environment from the grid frequency up to 6 GHz.

NOTE 1 This document assists in meeting the relevant EMC requirements as stated in SOLAS [5] Chapter IV, Regulation 6 and Chapter V, Regulation 17. Reference to this document is made in IMO Resolution A.813(19) [6].

The normative part of this document has been prepared as a product family EMC standard.

This document excludes:

• Equipment in the scope of TC 80.

NOTE 2 Equipment in the scope of TC80: ‘Maritime navigation and radiocommunication equipment and systems’ needs to comply with IEC 60945 which already covers the requirements stated in this document.

• The topic of harmonic distortion since it is discussed in IEC 60092-101 and IEC 60092-201 [7].

• The topic of termination of cable screens since it is discussed in IEC 60092-401.

• The topic of lightning and lightning protection on board ships since it is discussed in IEC 60092-401.

NOTE 3 Additional information on lightning protection may be found in DO-160G [8] section 22 & 23 Lightning and IEC 62305, especially part 1 [9] and 2 [10].

• Effects on humans, such as exposure to EM fields, and basic safety requirements such as protection against electric shock.

NOTE 4 Requirements to protect people from non-ionising are given by ICNIRP [11], [12]. National legislation might be more stringent.

NOTE 5 Common mode voltage in IT grids may exceed insulation values and cause a safety risk, which is not part of this standard. Especially in the frequency range of tens of kHz, filter components may be at risk.

NOTE 6 More information on “Basic safety” can be found in IEC Guide 104.

• The effect ripple voltage might have on components such as batteries and fuel cells.
