10、ed iiiForeword ISO (the International 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 whi

11、ch 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 closely with the International Electrotechnical Commission (IEC) on all m

12、atters 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 International Standards adopted by the technical committees are cir

13、culated 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 rights. ISO shall not be held respon

This third edition cancels and replaces the second edition (ISO 7206-2:1996), which has been technically revised. ISO

15、7206 consists of the following parts, under the general title Implants for surgery Partial and total hip joint prostheses: Part 1: Classification and designation of dimensions Part 2: Articulating surfaces made of metallic, ceramic and plastics materials Part 4: Determination of endurance properties
