26、ation) 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

27、 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 Standar

28、ds 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 Intern

29、ational 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.

38、rthgs ersedevr3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 15749-1 apply. 4 Vacuum system 4.1 Functional description The vacuum drainage system operates as follows: wastewater is collected from water closets, urinals, and bidets or from other drai

39、nage items in branch lines or manifolds; the wastewater is carried by means of the vacuum to a wastewater collector tank or a sewage treatment plant. The wastewater is evacuated in the form of a “plug” (sewage plug) owing to a pressure difference in the pipes before and behind the plug. 4.2 Descript

40、ion 4.2.1 Drain lines in the vacuum system commence at the drain of a drainage item. Vacuum-operated water closets have an integrated vacuum mechanism, other drainage items are connected to a separate vacuum valve via a short non-vacuum line. Drain lines in the vacuum system terminate at a vacuum-ge

41、nerating unit. 4.2.2 The wastewater is conveyed through pressure pipes from the vacuum generation unit to a collector tank or sewage treatment plant. NOTE The vacuum-generating unit may also be integrated into the collector tank or sewage treatment plant. 4.2.3 The sewage disposal pipes downstream o

42、f the collector tank or sewage treatment plant are not part of the vacuum system. For the design of these and other pressure pipes, ISO 15749-4 is applicable. Figure 2 of this standard shows an example of a vacuum-operated drainage system with drain lines. 4.2.4 Depending on the ship type, its archi

43、tecture, arrangement of ships rooms and number of persons, one, two or more vacuum sewage systems, which serve separate sections of a ship, can be provided. 4.3 Operating pressure The operating pressure is between 0,4 bar and 0,7 bar absolute pressure (corresponding to a permissible negative pressur

44、e of between 0,3 bar and 0,6 bar). 4.4 Drainage items 4.4.1 Vacuum-operated water closet A water closet fitted with a mechanism for drain and flush valve control shall be provided. The water volume for one flushing operation is approximately 1,2 litres. ENISO157493:2004IS-94751 O3:(4002E) I SO 4002

45、All irthgs ersedevr 34.4.2 Urinals and bidets These sanitary drainage items do not have built-in vacuum mechanisms and shall therefore be connected to a separate vacuum mechanism (vacuum valve) via connecting lines. 4.4.3 Washbasins and other drainage items These sanitary drainage items do not have

46、built-in vacuum mechanisms and shall therefore be connected to a separate vacuum mechanism (vacuum valve) via connecting lines. 5 Pipes Depending on the location, the following pipes shall be used for vacuum drain lines and vent lines: steel pipes in accordance with 5.1; steel pipes and CuNiFe pipes

47、 with spigot and socket joints, hereinafter referred to as spigot and socket pipes; CuNiFe pipes in accordance with 5.3; PVC-U pipes in accordance with 5.4; plastic pipes shall be approved in accordance with IMO-Resolution A.753 (18); pipes with low flame spread and smoke emission properties are at

48、the discretion of the classification society. For nominal bores see Table 1. Table 1 Nominal bores for drain lines Type of pipe Steel and CuNiFe pipes PVC-U and spigot and socket pipes 40 40 50 50 Nominal bore, NB 100 5.1 Steel pipes The following types of pipes are applicable: seamless steel pipes in accordance with ISO 4200 and ISO 9329-1, of S 235 JR; welded steel pipes in accordance with ISO 4200 and ISO 9330
