Because of the large difference between the long and short Knoop diagonals, the Knoop indenter is often better suited for determining variations of hardness over very small distances compared to the Vickers indenter.
If you need to be able to add standards to the monitoring service, you must register as a user with your own username and password. This standard is issued under the fixed designation E; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Testers that create indents at very low test forces must be carefully constructed to accurately apply the test forces exactly at the desired location and must have a high-quality optical system to precisely measure the diagonal or diagonals of the small indents. 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.

Enter your personal account email address to request a password reset: With this revision the test method was expanded to include the requirements previously defined in E In general, the Vickers indenter is better suited for determining bulk average properties as Vickers hardness is not altered by the d of the test force, from 25 to gf, because the indent geometry is constant as a function of indent depth.
Current edition approved Aug. Microindentation tests permit hardness testing of specific phases or constituents and regions or gradients too small for evaluation by macroindentation tests. While Committee E04 is primarily astm e — 11e1 pdf with metals, the test procedures astm e — 11e1 are applicable to other materials.

Note 2—While Committee E04 is primarily concerned with metals, the test procedures described are 111e1 to other materials. The Knoop indenter does not produce a geometrically similar indentation as a function of test force.
