The work of preparing International Standards is normally carried out throu

8、gh ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates

9、 closely with the InternationalElectrotechnical 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. Dr

10、aft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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 docume

ISO shall not be held responsible for identifying any or all such patent rights.ISO 22555 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, SubcommitteeSC 6, Navigation.BS ISO 22555:20071Ships and marine technology Propeller pitch indic

12、ators1ScopeThis International Standard specifies the construction, performance requirements, methods of testing andrequired test results for the propeller pitch indicators (hereinafter referred to as “indicator system”) required byclause 2.5.4, Regulation 19, chapter V, SOLAS 1974 (as amended, 2000)

13、.This International Standard is associated with IMO Resolution A.694 (17) and IEC 60945.Where a requirement in this International Standard differs from IEC 60945, the requirement in this InternationalStandard takes precedence.2 Normative referencesThe following referenced documents are indispensable

20、ment or machinery to which it isconnected at locations adjacent to or remote from the equipment or machinery. At the equipment or machinery,such systems will generally comprise a sensor and transmitter; at the observers location, such systems willgenerally contain an indicator.In general, the system

21、 construction shall comply with the following requirements.4.1.2 The indicator system enclosures shall be robust and constructed so as to facilitate easy adjustment andmaintenance.4.1.3 The indicator system shall be provided with an earthing terminal or shall be so constructed as to becapable of bei

22、ng connected to an electrical earth.4.1.4 An analog type indicator can be used as indicator(s) of the indicator system. It may be additionallyprovided by a digital type if fitted.4.2 TransmitterThe transmitter shall be driven by suitable means from the controllable pitch propeller activating mechani

23、sm.4.3 Indicator4.3.1 An analog indicator shall be of a centre-zero type (preferably circular). Where a circular scale indicator isused, the zero position shall be uppermost.The direction “Ahead” or “Starboard” shall be to the right of the zero graduation; the directions “Astern” or “Port”shall be t

24、o the left of the zero graduation.4.3.2 The digital indicator shall indicate the pitch angle as readily legible digital figures preceded by a symbolor letter(s) indicating direction. The directions “Ahead” or “Starboard” shall be identified by the “plus” sign or bythe letters “AH (ST)”, while “Aster

25、n” or “Port” shall be identified by a “minus” sign or by the letters “AS (PT)”.4.3.3 The maximum angle indicated shall be the same for both Ahead/Starboard and Astern/Port and shall beno less than .4.3.4 Scale graduations shall be no smaller than . Graduation marks corresponding to increments shallb

26、e more prominent than those for intervening increments.4.3.5 The pointer of an indicator shall be capable of being adjusted to zero.4015BS ISO 22555:200734.3.6 The letters and graduations on the dial shall be such that the direction of ahead and astern can be clearlydistinguished.4.3.7 All illuminat

27、ion and lighting of an indicator shall be adjustable down to zero, except the control of thedimmers which shall remain readable.4.3.8 The illumination and lighting of an indicator shall be arranged in order not to hinder an operators visionat night and in order to make the scale, pointer and letters

28、 as equally visible as possible, even in dim light or thedark.5 Performance requirements5.1 GeneralThe transmitter shall have the capacity to satisfy the requirements specified in 5.2, 5.3 and 5.4 when allconnected indicators are operating simultaneously. The manufacturer shall clearly state the max

29、imum numberof indicator(s) or the capacity of connected indicator(s) that can be supported by a transmitter.5.2 Calibration accuracyTo calibrate the indicator system, the shaft of a transmitter is gradually rotated from the zero position to themaximum angle ahead (Starboard) or astern (Port), and th

30、e angles shown by an indicator are recorded everyof rotation. The difference between the angle of the transmitter shaft and the corresponding value shown atan indicator shall be within of the sum of the maximum angle in both directions.5.3 Damping efficiencyIf a voltage is suddenly applied while the

31、 transmitter shaft is approximately at half of full-scale position and theindicator pointer is set to the zero position, the pointer shall be reset to that position within or less.5.4 Power supply fluctuation5.4.1 The performance specified in 5.1 and 5.2 shall be maintained when the system is subjec

32、t to the powersupply fluctuations.5.4.2 After repeated makings and breakings, the designated performance shall be demonstrated withoutcarrying out manual adjustments.5.4.3 When the rated voltage and frequency are subjected to the combinations of fluctuations, as given inTable 1, the designated perfo

33、rmance shall be demonstrated.5.5 Insulation resistance and high voltageWhen insulation resistance and high voltage tests are to be carried out, IEC 60092-504 may be applied.Table 1 Fluctuation rate of the rated voltage and frequencySettled conditionVoltage fluctuationFluctuating period: Frequency fl
