9、ardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to
10、be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standard
11、s are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard requires approval by at least 75 % of the member bodies casting
12、 a vote.Attention is drawn to the possibility that some of the elements of this International Standard may be the subject ofpatent rights. ISO shall not be held responsible for identifying any or all such patent rights.International Standard ISO 10133 was prepared by Technical Committee ISO/TC 188,

Annexes C and D are for information only.ISO 10133:2000(E) ISO 2000 All rights reserved vIntroduc
14、tionAnnex A specifies conductor requirements. Annex B specifies information and instructions to be included with theowners manual (ISO 10240). Annex C provides information on recommended system tests to be performed uponcompletion of the d.c. installation.This International Standard is intended to p
15、rovide protection against explosion and fires. It is important to realizethat this standard is not intended to achieve this purpose by itself. The manufacturer also needs to comply withadditional standards related to protection against the same possible hazards. These additional standards are listed
16、,in annex D, with a brief description of their contents. For complete understanding of the requirements, themanufacturer needs to refer to the actual standard. Compliance with all these International Standards will ensure ahigh level of safety in all craft, particularly in those using petrol or liqu
