GB/T 10250-2025Electrical and electronic installations in ships - Electromagnetic compatibility(EMC) - Ships with a metallic hull (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document replaces GB/T 10250-2007 "Electromagnetic compatibility of marine electrical and electronic equipment" and is consistent with GB/T 10250-2007.

In addition to structural adjustments and editorial changes, the main technical changes are as follows.

--- The scope of application of the standard has been modified to limit the scope of application to devices on metal hulled ships (see Chapter 1, 2007 Edition, Section 1 chapter);

--- Added description of the scope of use of EMC requirements equipment (see Chapter 1);

--- Deleted the relevant requirements for the equipment under test (see 3.14 of the 2007 edition);

--- Deleted the requirements for protected areas and reference areas (see 3.19 and 3.20 of the 2007 edition);

--- Added the definitions of "ground" and "grounding" (see 3.19, 3.20);

--- Deleted the definition of "region" (see 3.23 of the 2007 edition);

--- Added the definitions of "deck and bridge area", "general distribution area", "specialized distribution area" and "living area", and added the definitions of regional characteristics The definitions were supplemented (see 3.24, 3.25, 3.26, 3.27);

--- Added the definition of "field test" and "metal enclosure" (see 3.31, 3.32);

--- Added explanation of field test (see 5.1);

--- Changed the emission limits for equipment installed in the bridge and deck areas and the emission limits for equipment installed in the general distribution area (see Tables 2 and 3, Tables 2 and 3 of the 2007 edition);

--- Changed the minimum immunity requirements (see 7.2, 7.2 of the 2007 edition).

This document is equivalent to IEC 60533:2015 "Electromagnetic compatibility of electrical and electronic equipment on board ships - Metal hull ships".

1 Scope

This document specifies the minimum requirements for electromagnetic compatibility (EMC) of emissions, immunity and performance criteria for electrical and electronic equipment in ships.

This document helps to meet the requirements of SOLAS74 Chapter IV, Regulation 6 and Chapter V, Regulation 17 regarding electromagnetic compatibility. This document was referenced in resolution IMO A.813(19).

The normative part of this document has been adopted as a standard in the EMC series of standards.

This document gives further guidance and recommendations on measurement methods to achieve electromagnetic compatibility of the following electrical and electronic equipment in the following groups of equipment.

a) Group A. marine navigation and radio communication equipment and systems;

b) Group B. power generation and transformation equipment;

c) Group C. Equipment operating with pulsating energy;

d) Group D. switchgear and controlgear;

e) Group E. internal communication and signal processing equipment;

f) Group F. non-electrical parts and equipment;

g) Group G. Integrated systems.

IEC 60945 is the basic EMC standard for Group A and Group C. The EMC requirements specified in IEC 60945 also apply to.

- Bridge installation equipment;

- Devices close to receiving antennas;

- Equipment that can interfere with the safe navigation and radio communications of ships.

NOTE: The effects on persons exposed to electromagnetic radiation, as well as basic safety requirements such as protection against electric shock and equipment dielectric (strength) tests are not covered in this document.
