The Rockwell hardness test is less affected by surface rough-ness compared to other methods such as the Vickers or Brinell tests. It can provide reliable hardness measurements even on surfaces with moderate roughness, making it a practical choice for a wide range of materials and surface conditions.Units of hardness. There are a variety of hardness test methods in common use (e.g. Brinell, Knoop, Vickers and Rockwell). There are tables that are available correlating the hardness numbers from the different test methods where correlation is applicable.Rockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method. Here, the indenter makes a residual depth called the indent and it is .
