The International Electrotechnical Commission (IEC) published the standard IEC 60533, which covers shipboard electrical installations. Here's an excerpt:
The standard also provides essential structure and guidance. It includes a detailed for onboard equipment (from navigation systems to switchgear) to help apply appropriate EMC measures effectively. It specifies an EMC test plan (Clause 5) outlining the process from initial assessment to final installation validation, including instructions for in-situ testing on already-installed equipment. It also provides mitigation guidelines in Annex B, which includes practical advice on cable routing and shielding to prevent electromagnetic interference.
Outlines instructions for grounding metal shields of cables directly to the ship's metallic hull structure to maximize attenuation of stray RF currents.
Noise on high-frequency (HF) and very high-frequency (VHF) bands can disrupt critical ship-to-shore or ship-to-ship radio traffic. iec 60533 pdf
: Tailored for heavy power equipment, acknowledging higher baseline noise but requiring rugged immunity.
| Standard | Scope | Relation to IEC 60533 | | :--- | :--- | :--- | | | System-level EMC for metallic hull ships | Core standard for installations | | IEC 60945 | EMC and environmental tests for navigation equipment | Used for type approval of individual devices | | IEC 61892 series | EMC for mobile offshore units | Similar but adapted for dynamic positioning | | ISO 13297 | AC electrical systems for small craft (under 24m) | More basic, for recreational boats |
: Published recently in 2026, this paper provides a high-level overview of how IEC 60533 compares to other standards like IEC 60945 (for radio and navigation) and how they protect sensitive systems like maritime radar from interference. It specifies an EMC test plan (Clause 5)
It references other standards, such as IEC 61000, for general EMC methodologies, tailored for the maritime context.

The IEC 60533 standard is crucial for ensuring the safe and reliable operation of electrical and electronic equipment on ships. Electromagnetic interference can cause equipment malfunction, leading to accidents, injuries, and environmental damage. The standard helps to: Noise on high-frequency (HF) and very high-frequency (VHF)
The IEC 60533 standard provides several benefits to ship owners, operators, and builders, including:
Physical distancing between "noisy" power cables and "quiet" signal cables. 6. Conclusion
It covers both radiated and conducted emissions and immunity.
