The work of preparing International Standards is normally carried out through ISO tec
10、hnical committees. Each member body interested 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 part in the work. ISO collaborates closel
11、y 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/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft
12、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 documen
13、t may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20957-10 was prepared by Technical Committee ISO/TC 83, Sports and recreational equipment. ISO 20957 consists of the following parts, under the general title Stationary trainin
