The w
23、ork 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 on that committee. International organizations, governmental and non-govern
24、mental, 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 drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Dra
25、ft International Standards 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. Attention is drawn to the possibility that some of the elements of this Inte
26、rnational Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

28、ard specifies the minimum level of requirements for construction, operation and installation of geared link steering systems on all types of small craft of hull length up to 24 m. It excludes steering systems covered by ISO 8848 and ISO 9775. 2Terms and definitions For the purposes of this Internati
29、onal Standard, the following terms and definitions apply. 2.1 geared link system system in which rotation of the steering wheel positions the rudder blade by means of gearboxes, which converts the rotary motion to a push/pull force on the rudder operating lever, via a draglink assembly 2.2 draglink
30、component linking the rack operating lever to the rudder operating lever, which transmits the push and pull forces and allows rotational and angular misalignment 2.3 rudder operating lever component fixed to the rudder, transmitting the torque to the rudder shaft from the steering system 2.4 rack op
31、erating lever component fixed to the shaft of a steering system which rotates in relationship to movement of the steering wheel and achieves a corresponding movement of the rudder operating lever via the draglink 2.5 maximum output force force that the system can supply upon application of a 450 N f

34、hall be rated according to both its maximum permissible output torque and the corresponding rudder torques produced both at rudder midships and full lock. The manufacturers specification for the maximum permissible output torque shall be used to determine the tangential torque tests as specified in
35、6.3. 4.1.2Fasteners All threaded fasteners whose integrity affects safe operation of the steering system shall be provided with a means for locking. 4.1.3Materials The choice and combination of materials shall be such as to minimize the risk of corrosion and galvanic action. 4.2Specific 4.2.1Rudder
36、angle The steering system manufacturer shall specify the maximum rudder angle. 4.2.2Compass interference Materials used in the various components of the steering system as supplied shall not affect the accuracy and reliability of a compass mounted on the pedestal, if used, whatever the steering angl
37、e may be. 4.2.3Draglink The construction of the draglink shall be such that it will allow ? 20 mm of length adjustment and a minimum of 15? angular misalignment. Means shall be provided to secure the draglink after adjustments (see Figure 2). Where the rudder lever and the operating lever are in the
38、 same plane and there is no angular misalignment, a clevis fitting is permissible.

42、fastened to the structure of the craft, which should be reinforced as necessary. Threaded fasteners which may be expected to be disturbed by installation or adjustment procedures, whose integrity affects operation of the system such that separation or loss of the fasteners would cause sudden loss of

The strength of the rudder stops shall be adequate to withstand 150 % of the specified maximum output force at full lock of the
46、steering type as specified in 4.1.1 (see Figure 4).

49、he wheel shaft (see Figure 5). Figure 5 Axial force test 6.3Torque test With the rudder shaft fixed to prevent rotation and at its maximum operating angle, but with the operating levers not against a stop, apply a force of 150 % of rated maximum output torque for 10 cycles of at least 5 s duration via the steering wheel shaft (see Figure 6).
