15、British Standard has required careful comparison of the text of the “Blue Book” with the relevant IEC standards. This British Standard indicates only additional requirements or recommendations for UK industry that (BS) IEC 60092 lacks entirely or, in the opinion of JPEL/18, does not cover adequately

16、, although frequent reference is made to other relevant standards and publications. References to the applicable parts of (BS) IEC 60092 are given at the beginning of each clause.Licensed Copy: Wang Bin, na, Wed Sep 13 03:19:07 BST 2006, Uncontrolled Copy, (c) BSI BSI July 2006 iiiBS 8450:2006Use of

22、ilization of electrical energy for all purposes in ships of all descriptions, including, where relevant, inland and harbour craft, but excluding ships of war. NOTE For vessels smaller than 500 grt or with a length less than 50 m, IEC 60092-507 provides a basic standard for small vessel electrical in

23、stallations, including direct current systems not exceeding 50 V and alternating current systems not exceeding 250 V single phase or 500 V three phase.These recommendations are intended to provide satisfactory operation and safety, especially from fire and electrical shock, of installed equipment an

24、d portable and transportable equipment which is intended to be connected to the ships electrical distribution system. They relate principally to requirements for the installation, utilization, inspection and testing, but certain recommendations for the construction of electrical and electronic equip

25、ment are included.This British Standard is not applicable to the internal wiring of manufactured apparatus that is not wired on board. It is not intended to provide for every circumstance those of a special character may require appropriate advice.2 Normative referencesThe following referenced docum
