The work of preparing International Standards is normally carried out
24、through ISO technical 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 coll
25、aborates 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/IEC Directives, Part 3. The main task of technical committees is to prepare International St
26、andards. 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
27、of this part of ISO 3715 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

No definitions are given for the mechanical construction of the hub. Vocabulary for hydraulically operated controllable-pitch propeller plants is given in IS
