Hardness Methods: The Rockwell hardness test measures the depth of penetra-tion of an indenter into a material under a known load. It provides a hardness value based on the depth of penetration. Rockwell Hardness The Brinell hardness test involves indenting a material with a hard sphere under a specific load. Two diameters (x and yRockwell Hardness Test formula. Your testing equipment will provide an accurate calculation of the Rockwell hardness result, but there’s a formula to calculate the depth that’s measured into a Rockwell hardness number, which is: HR=N-(d/s) Where the value of: d is the penetration depth measured from point zero in mm s is either 0.001 mm or .The Rockwell hardness test method has a whopping 30 hardness scales defined by the indenter and the two loads. A Rockwell hardness value is a combination of the numerical hardness number and the Rockwell hardness scale letters preceded by letters HR. For example, a hardness value of 70 on Rockwell scale A is written 70 HRA.
