  scope: The Rockwell hardness test is an indentation hardness test using a verified
    machine to force an indenter, under specified conditions, into the surface of
    the material under test. The Rockwell hardness value is based on the permanent
    increase in the indentation depth as the force on the indenter is varied in a
    specified manner.
