3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Heated steel door

A steel door installed on a ship navigating in a low-temperature environment (3.4) that can be opened normally by heating an electric heating cable (3.3).

3.2 Traceheater

Devices designed to generate heat based on the principle of resistance typically consist of one or more metal conductors or conductive materials, and are then... Provide appropriate electrical insulation and protection.

Note: Electric heating tape (3.3), heating plate or heating pad can be used. [Source: IEC 60519-10:2013, 3.115]

3.3 Electric heat tracing cable

A cable in a circular or flat shape consisting of one or more independent or continuous electrically insulated heating elements.

Note: This cable can automatically adjust its heating output power according to the ambient temperature. [Source: IEC 60519-10:2013, 3.116]
