9、ional 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 bee
10、n 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 stand
11、ardization. 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
12、 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
13、 such patent rights. ISO 22555 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 6, Navigation.INTERNATIONAL STANDARD ISO 22555:2007(E) ISO 2007 All rights reserved 1 Ships and marine technology Propeller pitch indicators 1S c o p e This International Standar
14、d specifies the construction, performance requirements, methods of testing and required test results for the propeller pitch indicators (hereinafter referred to as “indicator system”) required by clause 2.5.4, Regulation 19, chapter V, SOLAS 1974 (as amended, 2000). This International Standard is as
15、sociated with IMO Resolution A.694 (17) and IEC 60945. Where a requirement in this International Standard differs from IEC 60945, the requirement in this International Standard takes precedence. 2 Normative references The following referenced documents are indispensable for the application of this d

19、neutral position on the equipment to which they are mounted 3.2 indicator means by which the state of the equipment or machinery is represented to an observer NOTE An indicator shows both the sense and magnitude of the information it presents. An indicator can be analog or digital. 3.3 analog type i
20、ndicator indicator that shows the pitch angle in a continuous way, such as by means of an arrow pointer and graduated scaleISO 22555:2007(E) 2 ISO 2007 All rights reserved 3.4 digital type indicator indicator that shows the pitch angle in a discrete, alphanumeric way 3.5 calibration accuracy differe
21、nce between the angle registered by the transmitter and the angle indicated by an indicator 3.6 damping efficiency time elapsed for the indicated angle to match the angle of the transmitter shaft 4 Construction of indicator system 4.1 Indicator system 4.1.1 An indicator system should show informatio
22、n on the state of the equipment or machinery to which it is connected 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 will generally contain an in
23、dicator. In general, the system 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 and maintenance. 4.1.3 The indicator system shall be provided with an earthing terminal or shall be so
24、constructed as to be capable of being 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 additionally provided by a digital type if fitted. 4.2 Transmitter The transmitter shall be driven by suitable means from the controll
25、able pitch propeller activating mechanism. 4.3 Indicator 4.3.1 An analog indicator shall be of a centre-zero type (preferably circular). Where a circular scale indicator is used, the zero position shall be uppermost. The direction “Ahead” or “Starboard” shall be to the right of the zero graduation;
26、the directions “Astern” or “Port” shall be to 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 symbol or letter(s) indicating direction. The directions “Ahead” or “Starboard” shall be identified by the “plus”
27、 sign or by the letters “AH (ST)”, while “Astern” 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 be no less than . 4.3.4 Scale graduations shall be no smaller than . G
28、raduation marks corresponding to increments shall be more prominent than those for intervening increments. 4.3.5 The pointer of an indicator shall be capable of being adjusted to zero. 40 1 5 ISO 22555:2007(E) ISO 2007 All rights reserved 3 4.3.6 The letters and graduations on the dial shall be such
29、 that the direction of ahead and astern can be clearly distinguished. 4.3.7 All illumination and lighting of an indicator shall be adjustable down to zero, except the control of the dimmers which shall remain readable. 4.3.8 The illumination and lighting of an indicator shall be arranged in order no
30、t to hinder an operators vision at night and in order to make the scale, pointer and letters as equally visible as possible, even in dim light or the dark. 5 Performance requirements 5.1 General The transmitter shall have the capacity to satisfy the requirements specified in 5.2, 5.3 and 5.4 when al
31、l connected indicators are operating simultaneously. The manufacturer shall clearly state the maximum number of indicator(s) or the capacity of connected indicator(s) that can be supported by a transmitter. 5.2 Calibration accuracy To calibrate the indicator system, the shaft of a transmitter is gra
32、dually rotated from the zero position to the maximum angle ahead (Starboard) or astern (Port), and the angles shown by an indicator are recorded everyof rotation. The difference between the angle of the transmitter shaft and the corresponding value shown at an indicator shall be within of the sum of
33、 the maximum angle in both directions. 5.3 Damping efficiency If a voltage is suddenly applied while the transmitter shaft is approximately at half of full-scale position and the indicator pointer is set to the zero position, the pointer shall be reset to that position within or less. 5.4 Power supp
34、ly fluctuation 5.4.1 The performance specified in 5.1 and 5.2 shall be maintained when the system is subject to the power supply fluctuations. 5.4.2 After repeated makings and breakings, the designated performance shall be demonstrated without carrying out manual adjustments. 5.4.3 When the rated vo
35、ltage and frequency are subjected to the combinations of fluctuations, as given in Table 1, the designated performance shall be demonstrated. 5.5 Insulation resistance and high voltage When insulation resistance and high voltage tests are to be carried out, IEC 60092-504 may be applied.
