23、orldwide 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

24、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 drafte

25、d 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 Stand

26、ard 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 8849 was prepared by

28、 Electrically operated direct-current bilge pumps 1 Scope This International Standard specifies requirements for electrically operated direct-current bilge pumps intended for use in removing bilge water from small craft with a hull length up to 24 m. It applies to electrically operated bilge pumps r

29、ated for less than 50 V direct current (d.c.). This International Standard does not cover pumps intended for damage control. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For und

30、ated references, the latest edition of the referenced document (including any amendments) applies.

31、001, Degrees of protection provided by enclosures (IP Code) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 automatic pump pump that is equipped with a sensing means that activates and deactivates the pump at predetermined liquid levels 3.2 i

32、gnition-protected device device that complies with the requirements of ISO 8846 3.3 nominal voltages voltages that are commonly used on small craft with direct current, such as 6 V, 12 V and 24 V 3.4 non-submersible pump pump designed to be operated above water 3.5 submersible pump pump designed to

33、be operated completely immersed in water 3.6 design voltage 113 % of nominal voltage 3002:9488OSINEENISO8849:2003IS:9488 O3002(E) 2 I SO 3002 All irhgts seredevr4 General requirements 4.1 Bilge pumps shall be designed to operate continuously at 87,5 % of nominal voltage, i.e. 10,5 V for a 12 V syste

34、m, 21 V for a 24 V system, up to their design voltage at the point within the range of performance recommended for the pump that results in the highest power consumption 4.2 Bilge pumps and devices used to convert bilge pumps to automatic operation shall be ignition-protected in accordance with the

35、requirements of ISO 8846 and shall meet the electrical requirements of ISO 10133. 4.3 Bilge pumps shall be rated in litres of water flow per minute or per hour at nominal voltage, at static pressures of 0 kPa, 10 kPa and 20 kPa, i.e. 0 m, 1 m and 2 m output lift, with 1,5 times the lift in a smooth-

36、 bore hose length of an inside diameter equal to the pump-outlet outside diameter fixed to the pump-outlet. The pump rating and capacities shall be stated in the installation and operating instructions provided with the pump. The pump rating shall include the maximum output pressure and lift at whic

37、h the pump ceases operation, i.e. the discharge of water. 4.4 Bilge pumps shall be provided with means of fastening them to the craft independently and securely. 4.5 Materials used in the construction of bilge pumps, which can be expected to come in contact with sea water, shall be selected or coate

38、d to be resistant to corrosion, galvanically compatible, and resistant to deterioration by bilge-cleaning agents and intermittent exposure to petrol (gasoline), oil and diesel fuel. 4.6 Submersible pumps shall be provided with a strainer or other means of preventing debris entering the pump inlet. I

39、nlet strainers and screens shall be designed such that they can be cleaned. 4.7 Installation and operating instructions shall be available for each bilge pump. An electrical diagram shall be provided. It shall identify each conductor and shall include the proper location of the control switch(es) in

40、 the circuit and the bonding connection, if applicable. The recommended overcurrent protection for non- integrally protected bilge pumps shall be stated. Installation instructions shall require remote-mounted pumps to be fitted with a strainer or other means of preventing debris from entering the pu

41、mp inlet. 4.8 Centrifugal and axial flow pumps shall be capable of operating dry at their design voltage for at least 7 h without creating a fire hazard. Alternatively, a means integral with the pumps shall be provided to shut the pump off automatically to prevent a fire hazard. 4.9 Positive or semi

42、-positive displacement pumps, i.e. those in which the impeller may be in continuous contact with the housing when operating dry, shall be capable of operating dry for at least 5 min without damage to the impeller or housing and for at least 1 h without creating a fire hazard. Alternatively, a means

43、integral with the pumps shall be provided to shut the pump off automatically to prevent a fire hazard. A label shall be provided cautioning against operating the pump dry for more than 1 min. 5 Electrical requirements 5.1 Bilge pumps shall be of the two-wire type or three-wire type if for manual or

44、automatic operation, with both power (positive) and return (negative) conductors insulated from the motor housing and the pump housing.
