IEC 60533: EMC Testing of Ships with Metallic Hulls

IEC 60533 is an international test standard dedicated to the electromagnetic compatibility (EMC) testing of ships with metallic hulls. IEC 60533 defines the minimum testing requirements for the components and devices integrated into ships with metallic hulls in both immunity and emissions testing. Following IEC 60533 protects equipment on board from electromagnetic interference caused by rogue emissions and the risk of unforeseen interference by lightning strikes, circuit breaker transients and radio transmitter radiation. This standard also helps with meeting IMO resolution A.813 requirements. The following equipment groups fall under the jurisdiction of IEC 60533:

• Group A | Radio communication and navigation equipment
• Group B | Power generation and conversion equipment
• Group C | Equipment operating with pulsed power
• Group D | Switchgear and control systems
• Group E | Intercommunication and signal processing equipment
• Group F | Non-electrical items and equipment
• Group G | Integrated systems

Note: For groups A and C, IEC 60945 is the basic EMC standard. IEC 60945 details the EMC requirements for bridge-mounted equipment, equipment proximal to receiving antennas and equipment with the potential to interfere with ship navigation and radio communication. The scope of IEC 60533 does not extend to the safety requirements like the protection of humans against electric shock, exposure to electromagnetic field or dielectric strength tests on equipment.
