A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters. Even though the indent impression is comparatively small when compared to the Brinell Hardness Test. The Rockwell hardness number (Rhn) must be specified with the scale name as prefix all the times. Precautions in Rockwell Hardness Testing. Before we test, we have to clean the surface from dirt. Advantages of Rockwell Hardness Testing MachineRockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).
