http://polymerdatabase.com/polymer%20physics/ShoreRockwell.html WebThe chief advantage of Rockwell hardness is its ability to display hardness values directly. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. The Rockwell C test is performed with a Brale penetrator (120°diamond cone) and a major load of 150kg.
