The work of preparing international Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for whi
4、ch a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
5、 matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS

10、their major component items, used for small traft with a Single outboard motor of 15 kW to 40 kW power. 2 Definitions For the purposes of this International Standard, the following definitions apply. 2.1 steering System: Assembly including all com- ponents necessary to transmit remote manual effort
11、to the outboard motor. 2,2 boat-mounted steering System: System in which an output ram guide tube is secured to the boat. 2.3 motor-mounted steering System: System in which an output ram guide tube is secured to the engine. 2.4 drag link: Device in a motor-mounted steering System by which the linear
12、 forte of the output ram is transmitted to the motor steering arm. 2.5 helm: Mechanism, exclusive of a steering- wheel or other means for manual application of controlling forte, by which controlling forte is fed into a steering System cable or other force- transmission means. 2.6 minimum retained S
13、ystem Performance: System capability after test(s) such that at least 90 % of the steering arc normally available each side of the mid-Position may be obtained by exertion of no more than 27 Nm of torque at the helm, through the wheel or other normal control. This criterion does not define steering
14、System per- formante while a boat is underway but is intended to provide quantitative limits for design and test purposes. 3 General requirements 3.1 When steering Systems are factory-installed in the boat, the complete System shall be supplied. In outboard motor-boats, the System shall be supplied
15、complete to the interface point at the ram output end as shown in figure 1.
