ISO 15749-2:2004(E) iv © ISO 2004 – All rights reserved Foreword 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 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 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 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 responsible 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 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

For their configuration, ISO 15749-4 applies. 4.1.3 Figure 1 gives an example of a drainage system with drain lines in a gravity system. 4.2 Operating pressure Pipes in sanitary systems (drain and vent lines) shall be designed such that the operating pressure 2) (internal pressure) cannot exceed 0,5 bar. 5 Pipes 5.1 General Depending on the location, the following pipes may be used for gravity drain lines and vent lines:  steel pipes in accordance with 5.2;  steel pipes and CuNiFe pipes with spigot and socket joints 3) in accordance with 5.3;  CuNiFe pipes in accordance with 5.4;  PVC-U pipes in accordance with 5.5; plastic pipes shall be approved in accordance with IMO Resolution A.753 (18).
