Standard Test Methods for Vickers Hardness and Knoop ...

Designation: E92 17 Standard Test Methods forVickers Hardness and Knoop Hardness of MetallicMaterials1 This Standard is issued under the fixed designation E92; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscriptepsilon ( ) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Scope* These test Methods cover the determination of theVickers Hardness and Knoop Hardness of metallic materials bythe Vickers and Knoop indentation Hardness principles.

3.2.2 microindentation hardness test, n—a hardness test, normally in the Vickers or Knoop scales, using test forces in the range of 9.807 × 10-3 to 9.807 N (1 to 1000 gf). 3.2.3 macroindention hardness test, n—a hardness test using test forces normally higher than 9.807 N (1 kgf). Macroinden-tation tests include Vickers, Rockwell and Brinell.
