Rockwell Indenter

Berg offers Rockwell hardness testers from Wilson.  In the Rockwell method, hardness is measured by the depth of indentation created in the test piece. Rockwell test equipment measures 3 depths of indentation and triangulates the final reading from them. The first depth measurement is obtained from a preliminary load, often called the preload or minor load, which is less than the final load. This is the reference load. After a reading under this load is obtained, the major load is applied, filling out the total required test load. To allow for the elastic recovery of the material, the load is held in position for a period known as the dwell time. After release of the major load, a final measurement is taken which compares the final load to the preload. This is the variation in the depth of indentation which the preload and final load have created in the material.
