11、etworking permitted without license from IHS -,-,- ISO 14705:2008(E) iv ISO 2008 All rights reserved Foreword 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
12、 carried out 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 w
13、ork. 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/IEC Directives, Part 2. The main task of technical committees is to prepare Int
14、ernational 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
15、the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14705 was prepared by Technical Committee ISO/TC 206, Fine ceramics. This second edition cancels and replaces the first edition (ISO 14705:2000), wh
16、ich has been technically revised.

18、 of monolithic fine ceramics at room temperature. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including a

22、ess value obtained by dividing the applied force by the surface area of the indentation computed from the mean of the measured diagonals of the indentations, assuming that the indentation is an imprint of the undeformed indenter NOTE 1 Vickers hardness may be expressed in two different units: a) wit
23、h units of GPa, obtained by dividing the applied force, in kN, by the surface area of the indentation, in mm2; b) Vickers hardness number, obtained by dividing the applied force, in kgf, by the surface area of the indentation, in mm2, without the units specified. NOTE 2 Use of Vickers hardness with
24、units of GPa is preferred.
