11、on information This British Standard was published by BSI and came into effect on 26 July 2006. It was prepared by Technical Committee JPEL/18, Electrical installations of ships. It supersedes all editions of the “Regulations for the Electrical and Electronic Equipment of Ships” (the IEE “Blue Book”
12、), which are withdrawn. Copyright is held jointly between BSI and Institution of Engineering and Technology.

16、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, although frequent reference is made to other relevant standards and publications. References to the applicable
17、parts of (BS) IEC 60092 are given at the beginning of each clause.

23、the generation, storage, conversion, distribution and utilization of electrical energy for all purposes in ships of all descriptions, including, where relevant, inland and harbour craft, but excluding ships of war. NOTEFor vessels smaller than 500 grt or with a length less than 50 m, IEC 60092-507 p
24、rovides a basic standard for small vessel electrical installations, 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 f
25、rom fire and electrical shock, of installed equipment and 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
26、 for the construction of electrical and electronic equipment 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 ad
