WebRockwell Hardness A specimen of at least 1/4 inch (6.35 mm) thickness is indented by a hard steel ball and the depth of indentation is measured. The Rockwell hardness is usually chosen for "harder" plastics. Shore Durometer Hardness A spring-loaded needle is placed against the sample 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.
