Note: IEC 60533 explicitly does not cover effects on human beings, focusing solely on equipment performance. 3. Equipment Groups Covered
Failing to comply with IEC 60533 can lead to catastrophic results. For example, a radar system interfering with a steering control signal could cause a collision. Common consequences of non-compliance include:

The standard, titled "Electrical and electronic installations in ships – Electromagnetic compatibility (EMC) – Ships with a metallic hull," defines the minimum requirements for emission, immunity, and performance criteria for shipboard equipment. Core Purpose and Scope
In the world of marine engineering and shipbuilding, electromagnetic compatibility (EMC) is not just a technical specification—it is a cornerstone of safety and reliability. With modern vessels housing everything from GPS navigation to automated engine controls and high-power propulsion systems, the risk of electromagnetic interference (EMI) has skyrocketed.
Unlike land-based installations, a ship is a confined metallic structure. Every cable, antenna, and power line is in close proximity. Without strict EMC controls, a VHF radio could jam a GPS receiver, or a thruster drive could corrupt the autopilot logic. Consequences range from nuisance alarms to total loss of control.
The 2015 edition introduced significant changes compared to its predecessor, reflecting advancements in technology and a deeper understanding of marine EMC challenges:
