In general, the Vickers indenter is better suited for determining bulk average properties as Vickers hardness is not altered by the choice of the test force, from 25 to gf, because the indent geometry is constant as a function of indent depth. To determine these differences requires a very small physical indentation.
NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.

The majority of Knoop tests of case hardness variations are conducted at forces from to gf. Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests. Astm e — xstm pdf To determine these differences requires a very small physical indentation.
For isotropic materials, the two diagonals of a Vickers indentation are equal in size.

A number in parentheses indicates the year of last reapproval. Because of the large difference between the long and short Knoop asttm, the Knoop indenter is often better suited for determining variations of hardness over very small distances compared to the Vickers indenter.

Ideally, the long diagonal is 7.
Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests. Test forces in the upper range of the force range defined in 1. Vickers Hardness Testing of Metallic Material that was under the jurisdiction of. Due to its rhombic shape, the indentation w384 is shallower for a Knoop indentation compared to a Vickers indentation under identical test conditions. With this revision the test method was expanded to include the requirements previously defined in E While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.
Metallography and is the direct responsibility of Subcommittee E The success of the specimen preparation procedure in removing preparation-induced damage can, and will, influence test results; this problem becomes more critical as the test force decreases.
