3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:NOTE Definitions included in this part are those having general application in IEC 60092. Definitions applying to particular apparatus or equipment which are only included within a single part of IEC 60092 are separately defined in that part only. 3.1 appropriate authority governmental body and/or classification society whose rules a ship is required to comply with 3.2 ocean-going ship ship not exclusively employed in the navigation of rivers or inland waters 3.3 essential services services essential for the navigation, propulsion, steering or manoeuvring of the ship, or for the safety of human life, or for special characteristics of the ship (for example special services) 3.4 accessory device, other than a luminaire (see IEC 60092-306), associated with the wiring and current- using appliances of an installation EXAMPLE Switch, fuse, plug, socket-outlet, lampholder or junction box. 3.5 bond connection of non-current-carrying parts to ensure continuity of electrical connection, or to equalize the potential between parts comprising, for example, the armour or lead sheath of adjacent length of cable, the bulkhead, etc. EXAMPLE Bulkhead and cables in a radio-receiving room. 3.6 earth general mass of the metal hull of the ship Note 1 to entry: In the USA, “ground” is used instead of “earth”. 3.7 earthed connected to the general mass of the hull of the ship in such a manner as will ensure at all times an immediate discharge of electrical energy without danger Note 1 to entry: A conductor is said to be “solidly earthed” when it is electrically connected to the hull without a fuse-link, switch, circuit-breaker, resistor, or impedance, in the earth connection. Note 2 to entry: In the USA. “grounded” is used instead of “earthed”. 3.8 basic insulation insulation of hazardous-live-parts which provides basic protection Note 1 to entry: This concept does not apply to insulation used exclusively for functional purposes [SOURCE: IEC 60050-1 95:1 998, 1 95-06-06]3.9 supplementary insulation independent insulation applied in addition to basic insulation, for fault protection [SOURCE: IEC 60050-1 95:1 998, 1 95-06-07] 3.1 0 double insulation insulation comprising both basic insulation and supplementary insulation [SOURCE: IEC 60050-1 95:1 998, 1 95-06-08] 3.1 1 reinforced insulation insulation of hazardous-live-parts which provides a degree of protection against electric shock equivalent to double insulation Note 1 to entry: Reinforced insulation may comprise several layers which cannot be tested singly as basic insulation or supplementary insulation [SOURCE: IEC 60050-1 95:1 998, 1 95-06-09]
