9、 Standards bodies (ISO member bodies). The work of preparing international Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internationa

10、l 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 matters of electrotechnical standardization. Draft International Standards adopted by the technical committe

11、es 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 ISO 9775 was prepared by Technical Committee ISO/TC 188, Small traft. NOTE 1 This International Standard specif

12、ies requirements and test methods for remote steering Systems as cited in clause 1.

15、thods for remote push-pull cable steer- ing Systems and 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

16、com- ponents necessary to transmit remote manual effort 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: Devic

17、e in a motor-mounted steering System by which the linear 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

18、 other force- transmission means. 2.6 minimum retained System 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

19、normal control. This criterion does not define steering 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

20、. In outboard motor-boats, the System shall be supplied complete to the interface point at the ram output end as shown in figure 1.

If the boat

23、is suitable for boat-mounted steering Systems, it shall also be specified whether weil mounting, transom mounting or both (see figure2) may be used. 3.4 All threaded fasteners use of which affects safe Operation of the steering System shall incorporate locking means. 3.5 Threaded fasteners use of wh

24、ich affects safe Operation of the steering System and which are in- tended to be mounted or adjusted when installing the steering System in the boat, and which may be expected to be disturbed by installation or adjust- ment procedures, shall be locked by a locking de- vice provided with instructions

NOTE 2 For assemblies not intended to be disassem- bled for installation, the choice of locking means is within the discretion of the System manufacturer. 3.5.3 A locking device shall be so designed that its presence tan be determined by visua

27、l inspection or feel by a layman after installation. 3.6 Connection fittings including quick-disconnect fittings relying upon a spring or springs to maintain the connection shall not be used.
