15、s seredevrForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for
16、 which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on a
17、ll matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are
18、 circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member 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 re
19、sponsible for identifying any or all such patent rights. ISO 5483 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery. This second edition cancels and replaces the first edition (ISO 5483:1977), which has been technically revised. BSISO5

Recommended criteria are identified by the use of the key word “should”, and while not mandatory are consider
21、ed to be of primary importance in providing serviceable, economical and practical designs. Deviations from the recommended criteria should occur only after careful consideration, extensive testing and thorough service evaluation have shown alternative methods to be satisfactory.

23、 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 facilities for both instances. 2 Normative references The following referenced documents are indispensable for the ap

28、ess 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 two categories of drain plugs: square wrench connection for water tanks, and hexagonal wrench connecti
29、on for oil tanks. 4 General assembly arrangement 4.1 Assembly For Type A, refer to Figure 1 and Table 1. For Type B, refer to Figure 2 and Table 2.
