9、. The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non
10、-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part
11、 2. The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5483 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommit

This second edition cancels and replaces the first edition (ISO 5483:1977), which has been technically revised. -,-,- ISO 5483:2003(E) ISO 2003 All rights reserved v Introduction Throughout this International Standard, the minimum essential criteria are identified by
14、the use of the key word “shall”. Recommended criteria are identified by the use of the key word “should”, and while not mandatory are considered to be of primary importance in providing serviceable, economical and practical designs. Deviations from the recommended criteria should occur only after ca
15、reful consideration, extensive testing and thorough service evaluation have shown alternative methods to be satisfactory.

16、pecifies dimensions and materials for welding rings and drain screws situated at the bottom of oil and water tanks. Oil and water tanks occur as: built-in tanks, as an integrated part of the hull structure, and, detachable tanks, located in appropriate rooms and compartments. This standard covers fa

21、plicable, especially where flush mounting with the outer surface of hull-plating at any plate thickness is required, and Type B, which is usable in all other instances where the above-mentioned requirement is not applicable. NOTE Both Type A and Type B arrangements are identified by the following tw
