It is identical with ISO 10592:1994 published by the International Organisation for Standardization (ISO). Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

Members of IEC and ISO maintain registers of currently valid International Standards. ISO 10240, Small craft Owners manual1) 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 system maximum working pressure relief valve pressure setting 3.2 system test pressure non-destructive test pressure, at least one and half times the system maximum operating pressure 3.3 minimum retained system performance system capability after test(s) such that at least 90 % of the steering arc normally available to 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 NOTE 1This criterion does not define steering system performance while a boat is underway but is intended to provide quantitative limits for design and test purposes. 3.4 craft-mounted hydraulic system system in which a cylinder is secured to the boat 3.5 motor-mounted hydraulic system system in which a cylinder is secured to the engine 3.6 drag link link in a motor-mounted steering system by which the linear force of the output ram is transmitted to the motor steering arm 4 Outboard motor and inboard-outdrive requirements 4.1 Steering stops on an outboard motor shall permit at least 30? of angular movement to either side. The design torque at the rudder stock shall be sufficient to put the helm from hard over to hard over (30? port to 30? starboard or vice versa) in not more than 30 s. 4.2 Outboard motors shall meet the applicable dimensional requirements indicated in Figure 1 and Figure 2. 4.3 Necessary fittings to attach an outboard motor to the cylinder output rod shall be supplied with the outboard motor. 1)To be published.

Appropriate written information and installation instructions shall be provided, clearly indicating 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 force of 3 300 N, applied at the steering arm connection point normal to the steering arm in its normal plane of operation throughout the maximum steering arc, will 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 geometry to ensure that a torque of 680 Nm applied on the outdrive steering axis will not result in a steering component loading greater than that specified in 9.3.2. NOTEThe tube may be threaded equal length on both ends or reversible for port steering installation.

The complete hydraulic steering system shall be designed to withstand conditions of pressure, vibration, shock and movement without failure or leakage. 5.5 Hydraulic systems with a non-functional autopilot shall be capable of operation throughout an ambient temperature range of 10?C to + 60?C and be capable of withstanding storage at 30?C to + 60?C. 5.6 Fittings, hoses, piping and components shall be capable of withstanding the system test pressure without permanent deformation, external leakage or other malfunction. 5.7 Materials used in hydraulic steering systems shall be resistant to deterioration by liquids or compounds with which the material may come in contact under normal marine service, e.g. grease, lubricating oil, hydraulic fluid, common bilge solvents, salt and fresh water. 5.8 In vessels over 12,5 m in length, the hydraulic steering system shall be capable of putting the rudder over from 30? on one side to 30? on the other in not more than 30 s when the vessel is at maximum forward service speed with the rudder totally submerged, and, if normally operated, shall be designed to prevent violent recoil of the steering-wheel. 6 Hydraulic fluid The type of hydraulic fluid to be used in a hydraulic steering system shall be specified by the manufacturer of the steering system and shall be stated in the owners manual. The hydraulic fluid shall be non-flammable or have a flash point of 157?C or over. 7 Materials In addition to the general requirements of clause 5 the following requirements shall be met. 7.1 Components of different materials shall be galvanically compatible or separated by a galvanic barrier. 7.2 Plastics and elastomers which may be exposed to sunlight shall be chosen to resist degr
