14、BS.0 ISO ISO 10592:1994(E) Foreword ISO (the International 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. Esch member body interested

15、 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-governmental, in liaison with ISO, also take patt in the work. ISO collaborates closely with the International Electrotechnical Comm

16、ission (IEC) on all matters of electrotechnical standardization. Draft 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. Internat

19、raulic steering Systems and components from the wheel to the interface Point for outboard motor, inboard motor and inboard-Outdrive steering arrangements, used on small traft of up to 24 m length of hull. Accessories connecting output rams to tiller arms or equivalent are not included. 2 Normative r

20、eference The following Standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the edition indicated was valid. All Standards are subject to revision, and Parties to agreements based on this International

21、 Standard are encouraged to investigate the possibility of applying the most re- cent edition of the Standard indicated below.

28、f motor turn and tilt, there shall be no damaging interference between the motor, its ac- cessories, and both the traft-mounted and the motor-mounted System, if the motor is designed for both Systems. Appropriate written information and installation instructions shall be provided, clearly indi- cati

29、ng the type of steering System(s) that should be used. 4.5 Outboard motors shall be designed so that the geometry ensures that a static forte of 3 300 N, ap- plied at the steering arm connection Point normal to the steering arm in its normal plane of Operation throughout the maximum steering arc, wi

30、ll not result in steering output ram loadings greater than those specified in 9.3.1. 4.6 The steering arm of an outboard motor shall be provided with a 3/8 in-24 UNF thread, or a plain hole of 9,65 mm to 9,9 mm diameter at the connection Point. 4.7 Inboard-Outdrives shall be designed with proper geo

31、metry to ensure that a torque of 680 Nm applied on the Outdrive steering axis will not result in a steering component loading greater that that specified in 9.3.2.
