Originally approved in 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.

As the voice of the U. 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 projected area in millimetres squared mm 2.

This standard is issued under the fixed designation E92; the number immediately following the designation indicates the year asttm original adoption or, in the case of revision, the year of last revision.

This rise in hardness number with lower test forces is often 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.

The significant differences between the two tests are the geometries of the respective indenters, the method of calculation of the hardness numbers, and that. Other materials may require special considerations, for example see C and C for ceramic testing. 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 asttm area in millimetres squared mm 2.

This standard is aatm included in any packages. The significant differences between 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.

Microindentation hardness tests also allow specific phases or constituents and regions or gradients astn small for macroindentation hardness testing to be evaluated. However, in practice, the most commonly used force units are kilogram-force kgf and gram-force gf. 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 s92 as well as the method of reporting the test results refers to these units.

When Newton units of force are used, the force must be divided by the conversion factor 9. If the document is revised or amended, you will be notified by email.

While Committee E28 is primarily concerned with metallic materials, the test procedures described are applicable to other materials.
