The Rockwell hardness test uses a small diameter steel ball indenter for soft materials and a diamond cone indenter for hard materials. The indenter is pressed into the material for a fixed time and its penetration depth is measured automatically by the Rockwell test machine and converted into the Rockwell hardness number (HR).

G. Sundararajan, M. Roy, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Rockwell Hardness Testing. In a Rockwell hardness test, initially a minor load of 10 N is applied and the zero datum position is established. The major load (60, 100, or 150 N) is then applied for a specific period (a few seconds) and removed, leaving the minor load applied.

The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B – A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation.

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.

The choice is not only between the regular hardness test and superficial hardness test, with three different major loads for each, but also between the diamond indenter and the 1/16, 1/8, 1/4 and 1/2 in. diameter steel ball indenters.

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.
