25、devrForeword 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 which

26、 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 all mat

27、ters 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 circu

28、lated 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 responsi

29、ble for identifying any or all such patent rights. ISO 15749-2 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3, Piping and machinery. ISO 15749 consists of the following parts, under the general title Ships and marine technology Drainage systems on ships

30、and marine structures: Part 1: Sanitary drainage-system design Part 2: Sanitary drainage, drain piping for gravity systems Part 3: Sanitary drainage, drain piping for vacuum systems Part 4: Sanitary drainage, sewage disposal pipes Part 5: Drainage of decks, cargo spaces and swimming pools ENISO15749
