11、iv ISO 2000 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 carried out through ISO technical committees. Each member body inter
12、ested 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 closely with the International Electrotechnical
13、 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publicatio
14、n 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such
15、 patent rights. International Standard ISO 14705 was prepared by Technical Committee ISO/TC 206,Fine ceramics.

17、describes the method of test for determining the Vickers and Knoop hardness of monolithic fine ceramics at room temperature. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dat
18、ed references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For und
19、ated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

21、s of this International Standard, the following terms and definitions apply. 3.1 Vickers hardness 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 th
22、e undeformed indenter Vickers hardness may be expressed in two different units: a)with 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 indenta
