10、onal 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. Each member body interested in a subject for which a technical committee has been
11、 established has the right to be represented on that committee. International organizations, governmental 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 standa
12、rdization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
13、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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all
14、such patent rights. ISO 15652 was prepared by Technical Committee ISO/TC 188, Small craft.

Threaded fasteners whose integrity affects operation of the system, such that separation or loss of the fastener would cause sudden loss of steering without warning, and that may be expected to be disturbed by installation or adjustment procedures, shall be referenced by instructions for
26、correct assembly and shall either be locked by a device whose presence is determinable by visual inspection, or by feel, following assembly, or incorporate integral locking means, provided the fastener cannot be omitted or substituted without making the system inoperable. NOTESelf-locking nuts with
27、plastic inserts that create mechanical plastic interference meet the requirements of this subclause. Loose lockwashers, distorted thread nuts, or separately applied adhesives are prohibited. Plain threaded jam nuts are prohibited. For assemblies not intended to be disassembled for installation, the
28、choice of locking means is at the discretion of the system manufacturer. Mechanical fittings relying upon spring force for connection integrity shall not be used. 4.2Helms Helms that use a steering wheel shall be permanently marked with the manufacturers recommendation of the largest wheel diameter
29、and the deepest wheel dish that may be used. See Figure 1. Helms that incorporate a handlebar shall be permanently marked with the manufacturers recommendation of the largest handlebar length and greatest effective offset that may be used. Helms that incorporate a joystick shall be permanently marke

44、 on the steering-wheel rim applied tangentially to the rim; at any point of maximum leverage of a handlebar applied in the direction of steering arc; at the point of maximum leverage of a joystick, applied perpendicularly to the joystick and in the direction of steering movement. 5.4Fatigue test The
