ASTM E92 – 82() Standard Test Method for Vickers Hardness of Metallic Materials
E922 standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests.
However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf.

Other materials may require special considerations, for example see C and C for ceramic testing. The significant differences between the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that. NOTE 1—The Vickers and Knoop hardness numbers were originally defined in terms of the test force in kilogram-force kgf and the surface area or ast, area in millimetres squared mm 2.

This standard is also available to be included in Standards Subscriptions. Hence, the Knoop hardness test is very useful for evaluating hardness gradients since Knoop indentations can be made closer together than Vickers indentations by orienting the Knoop indentations with the short diagonals in the direction of the hardness gradient.
Anumber in parentheses indicates the year of last reapproval. Other materials may require special considerations, for example see C and C atsm ceramic testing. Last previous edition approved in as E92—82 which was withdrawn July and reinstated in February Proceed to Checkout Continue Shopping.
This rise in hardness number with d92 test forces is astj more significant when testing higher hardness materials, and is increasingly more significant when using test forces below 50 gf see Test Method E NOTE 2—While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials.
This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests.
Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated. We have no amendments or corrections for this standard. However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results refers to these units.

The significant differences atsm the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that Vickers hardness may be used at higher force levels than Knoop hardness. The significant differences between the two tests are the geometries astj the respective indenters, the method of calculation of the hardness numbers, and that Vickers hardness may be used at higher force levels than Knoop hardness. The Vickers and Knoop hardness numbers were originally defined in terms of the test force in kilogram-force kgf and the surface area or projected area in millimetres squared mm 2.

Recommendations for microindentation testing can be found in Test Method E Current edition approved Feb. This standard is issued under the fixed designation E92; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

When Newton units of force are used, the force must be divided by the conversion factor 9. Anumber in parentheses indicates the year of last reapproval. Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons N.
