The work of preparing International Standards is normally carried out through ISO technical committees. Eac

24、h 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 Internation

25、al 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 Standard

26、s 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.

NOTE Wastewater from spaces in which live animals are accommodated is classified as sewage water and shall be discharged in accordance with MARPOL regulatio

35、purposes of this document, the terms and definitions given in ISO 15749-1 and the following definition apply. 3.1 drain line pipeline which serves to carry wastewater from drains directly overboard or into the bilge using the gravity principle without a collector tank or sewage treatment plant being

36、 connected in between 4 Drainage of exposed decks and non-weathertight spaces 4.1 Basic considerations 4.1.1 Wastewater from exposed decks and superstructure or deckhouses, without weathertight doors, shall be discharged overboard. 4.1.2 Open superstructure decks may be drained directly overboard or

37、 via pipes leading from one deck to the next lower deck. 4.1.3 The weather deck shall be drained overboard mainly via openings in the bulwark. Residual wastewater that cannot be drained via these openings has to be discharged overboard via drain lines. 4.1.4 The drain line from the funnel or stack t

38、op should not terminate on an exposed deck owing to the soot that may be contained in the wastewater. This line may, taking the quantity of wastewater occurring into consideration, be connected to other lines draining exposed decks and leading directly overboard. 4.2 Drains Drains shall be fitted wi

39、th water discharges without odour seals. 4.3 Piping 4.3.1 Types of pipes For deck drainage, the following pipes may be used: steel pipes in accordance with 9.1; spigot and socket steel pipes, but only in the exposed superstructure deck area. Plastic pipes may be used only with the approval of the cl

40、assification society. 4.3.2 Nominal bore The nominal bores of the above-mentioned pipes usually range from NB 40 to NB 150. Table 1 gives information about the possible amount of drainage, depending on the nominal bore and assuming gravity delivery lines. ENISO157495:2004 3Table 1 Amount of drainage

42、ships Cargo spaces on the bulkhead deck of passenger ships or on the freeboard deck of cargo ships, respectively, shall be discharged directly overboard in case of 5 list. Drain lines to overboard shall have a non-return fitting in accordance with ISO 15749-4. Wastewater from refrigerated cargo spac

43、es is generally drained into the bilge via separate drain lines. If the deck edge is immersed with the ship listing less than 5, the wastewater shall be drained into sufficiently dimensioned collector tanks. These collector tanks shall be equipped with level alarms and shall be capable of being drai

44、ned overboard via appropriate equipment. Additionally, it shall be guaranteed that scuppers are dimensioned and arranged in sufficient numbers such that accumulation of free water will be prevented, dimensioning of the gravity delivery line shall take into account the volume of water from the deluge

45、 system and that from the required fire-hose nozzles, water polluted with fuel and/or dangerous products cannot be drained into engine rooms or other spaces with ignition sources, and the scupper in holds protected by a CO 2 -plant shall have installations which prevent the leakage of fire-extinguis

46、hing gas. 6 Drainage of swimming pools 6.1 Swimming pools on exposed decks The discharge lines of drains and swimming pool overflows on exposed decks shall be routed directly over the side in the same way as the drain lines for deck drainage. If the stability calculations for a ship do not include a

47、 swimming pool on the exposed deck, the relevant classification society shall be consulted as to whether and how emergency drainage has to be provided. 6.2 Indoor swimming pools 6.2.1 Swimming pools above the freeboard deck See 6.1 and Clause 8. ENISO157495:20044 6.2.2 Swimming pools on and below th

48、e freeboard deck Swimming pools located in this area may be drained directly overboard via suitable closing devices in accordance with ISO 15749-4. 6.3 Piping Steel pipes in accordance with 9.1 or 9.2 shall be used. 7 Wastewater discharges Drain line outlets in the shell coming from exposed decks, vehicle decks, and swimming pools shall not be located in the vicinity of gangways and in areas where lifeboats are launched. 8 Shut-off fittings (c
