Due to its rhombic shape, the indentation depth is shallower for a Knoop indentation compared to a Vickers indentation under identical test conditions.

Notes are optional and private. 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. Because of the satm difference between the long and short Knoop diagonals, the Knoop indenter is often better suited for astm e384 – 11e1 variations of hardness over very small distances compared to the Vickers indenter.
