IEC 60092-354 mandates LSZH materials—typically halogen-free compounds based on thermoplastic polyethylene (HTPE), ethylene vinyl acetate (EVA), or polyurethane (PU). These materials meet stringent EN 61034 smoke emission criteria: less than 50% optical density when tested in a closed chamber, and minimal evolution of corrosive gases (measured as hydrochloric acid equivalent per EN 50267-2-1). For additional mechanical protection, ship cables are almost always specified with armoring: a steel wire or steel tape wrapping applied over the jacket.

IEC 60092 MV Cables vs. IEEE 1580 Type MMV: A Specifier’s Guide for Shipboard Power Distribution

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.
