19、O 22794:2009ISO 22794:2007(E)iv ISO 2007 All rights reservedForeword 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 commit

20、tees. Each member bodyinterested in a subject for which a technical committee has beenestablished 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 closelywith the Inter

21、national 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 International Sta

22、ndardsadopted 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 subje

23、ct of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22794 was prepared by Technical Committee ISO/TC106, Dentistry, Subcommittee SC 8, Dentalimplants. In this corrected version of ISO 22794:2007 changes have been made to the list of Normative ref

24、erences (Clause 2) and to the Bibliography. Consequently cross-references in subclauses 5.2, 5.5.5, 5.7, 5.8 and 5.9.2 have been altered. Further, new subclauses 5.5.3 and 5.5.4 have been designated with the former 5.5.3 becoming 5.5.5. BS EN ISO 22794:2009ISO 22794:2007(E) ISO 2007 All rights reser
