Rockwell hardness test has to do with the application of a standard load (Based on the type of material) thro ugh a standard indentor (cone or ball indentor) for a standard duration of time.
In the Rockwell hardness testing, the indenter applies the first load to the test piece. The indent is then measured, and the value obtained is used for the base calculations. This first load is removed, and another heavier load is applied to the indenter on the test piece. The Rockwell hardness of the test piece is calculated by subtracting .
