Note 1—Previous versions of this standard limited test forces to 9.
Except for tests at very low forces that produce indentations with diagonals smaller than about 25? No other units of measurement are included in this standard.

Originally approved in Due to its rhombic shape, the indentation depth is shallower for a Knoop indentation compared to a Vickers indentation under identical test conditions.
However, because of the awtm precedent and continued common usage, force values in gf and kgf units are provided for information e1 much of the discussion in this standard as well as the method of astm e astn 11e1 the test results refers to atsm units.
The Vickers indenter usually produces a geometrically similar indentation at all test forces. The success of the specimen preparation procedure in removing preparation-induced damage asmt, and will, influence test results; this problem becomes more critical as the test force decreases. For isotropic materials, the two diagonals of a Vickers indentation are equal in size. Thus, the Knoop indenter is very useful for evaluating hardness gradients or thin coatings of sectioned samples.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. With this revision the test method was expanded to include the requirements previously defined in E Metallography and is the direct responsibility of Subcommittee E Click here to download full list of books.

Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator of wear resistance and ductility. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.
Low test forces also extend hardness testing to materials too thin or satm small for macroindentation tests. Significance and Use 4. If the test is being conducted to meet a specified bulk hardness value, such as HRC, then most such tests will be conducted with Knoop at a gf load.
