9、 member bodies). 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, gover

10、nmental and non-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 D

11、irectives, Part 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

12、bodies casting 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 techno

13、logy, Subcommittee SC 3, Piping and machinery. 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 vIntroduction Throughout this International Standard, the minimum essential criteria are identi

14、fied by 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

15、after careful consideration, extensive testing and thorough service evaluation have shown alternative methods to be satisfactory.

16、ndard specifies 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 co
