    The regular Rockwell hardness testing scales use heavier force (load) levels. For these scales, the preliminary force (minor load) level is 10 kgf and the standard total force (load) levels may be 60 kgf, 100 kgf or 150 kgf. The superficial Rockwell hardness testing scales use lighter force (load) levels, typically for use on thinner materials.
