IEC 60331-21

9 Min Read
The European and American approaches to cable engineering reflect fundamentally different environmental threat models. BFOU cables manufactured to NEK 606 specifications incorporate halogen-free insulation, SHF2 H-M compound sheathing, and mica glass tape (MGT) as a fire barrier, enabling uninterrupted power delivery during fire situations in accordance with IEC 60331-21. This design prioritizes survival of critical systems during extreme thermal events—a recognized hazard in confined spaces such as engine rooms and living quarters aboard offshore vessels.

The International Electrotechnical Commission (IEC) is the world's leading independent non-profit international standard-setting organization for electrical, electronic, and related technologies. Founded in 1906 with British Scientist Lord Kelvin as its first president, the IEC has over a century of expertise in developing international standards that form the basis for national and international standardization. All IEC standards are consensus-based and represent the needs of key stakeholders, with every member country having an equal vote.
