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. Performing hardness testing can take many forms, depending on the protocols followed. There are many hardness scales and one of the most common is the Rockwell scale. To convert Rockwell Hardness to Tensile Strength, use a polynomial equation developed by modeling the tested materials. The general formula is: TS = c3 * RH^3 + c2 * RH^2 + c1 .profiles. The Rockwell test is the most popular indentation hardness test and is used in a wide variety of applications. Advantages of the Rockwell Test There are several reasons for the popularity of the Rockwell test. The test itself is very rapid. On a manually operated unit, a Rockwell test takes only five to ten seconds,
