What is the difference between “Flame Retardant” and “Fire Resistant” marine cables?

Flame Retardant (IEC 60332): Prevents the cable from spreading a fire. It will eventually fail electrically if the flame persists.

Fire Resistant (IEC 60331): Features a mica tape barrier that allows the cable to maintain circuit integrity (keep power flowing) for 90–180 minutes during an active fire. These are vital for emergency steering, fire pumps, and alarms.
