What is Rockwell hardness testing? The Rockwell Hardness Test is generally a non-destructive test performed on samples when it’s necessary to determine how hard a material is. It’s generally considered easier to perform compared to other methods, like Vickers or Brinell hardness testing. Another advantage is the small area of indentation needed to carry out the .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.We also offer repair services for 3rd party hardness testing systems as well depending on parts availability from the manufacturer.
