This part of IEC 60092 is applicable to screened and unscreened cables for control and instrumentation circuits on ships and offshore units. The cables have extruded solid insulation with a voltage rating of 150/250V (300V) (see Clause 4) and are intended for fixed installations. The various types of cables are given in Clause 5. The constructional requirements and test methods are aligned with those indicated in IEC 60092-350, unless otherwise specified in this document. The object of this document is to standardise cables whose safety and reliability are ensured when they are installed in accordance with the requirements of IEC 60092-352; to lay down standard manufacturing requirements and characteristics of such cables directly or indirectly bearing on safety, and; to specify test methods for checking conformity with those requirements.
