15、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 established has the right to be repres
16、ented 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 standardization. International Standards are
17、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 voting. Publication as an International
18、 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 such patent rights.

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, sha
30、ll be referenced by instructions for 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 in
31、operable. NOTE Self-locking nuts with 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
32、be disassembled for installation, the 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. 4.2 Helms Helms that use a steering wheel shall be permanently marked with the manufacturers recomm

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 incorporat

47、: at any point 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. 5.4 F
48、atigue test The steering components shall withstand a cyclic force resulting from tension and compression, applied axially to the output of the steering cable, with the helm locked at the mid-travel position. This force shall be applied for 50 000 reversals without causing separation. 5.5 Impact tes

The helm shall withstand a single impact of on the steering-wheel rim, on the hand grip of a handlebar, or on the hand grip of a joystick, without deformation that would cause loss of minimum retained system performance, propagation of any cracks existing before this test, or the appearance of new cracks. 1 430 N 540 N 5s 100 mm 100 mm 100 mm 360 N 5s 360 N h= 210 mm 170 Nm SANS 15652:2008This standard may only be us
