The work of preparing International Standards is normally carried out through IsO 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 drafted in accordance with the rules given in the ISO/lEc 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 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 ISO 8705 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 23, Mopeds. This second edition cancels and replaces the first edition (isO 8705:1991) which has been technically revised. @ Iso 2005 - All rights reserved ISO 8705:2005(E) Introduction environment in which this combination is used form a unique closed-loop system. However, the evaluation of the moped/rider combination stability is extremely complex because of interaction of the intrinsic moped stability, the influence of position of the rider and his response to continuously changing conditions. In the evaluation of moped stability, the determination of the kinetic characteristics of the moped/rider combination is considered an important part of the design parameters of the vehicle itself. The test procedure described in this International Standard deals with one aspect of the kinetic characteristics: the determination of the centre of gravity of the moped and of the moped/rider combination.
