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 .1.5 Units— At the time the Rockwell hardness test was developed, the force levels were specified in units of kilograms-force (kgf) and the indenter ball diameters were specified in units of inches (in.). This standard specifies the .testing is covered by ASTM test method E 18. While all indentation hardness tests generally serve the same purpose, each one has definite advantages that make the test more applicable to certain types of materials and part geometries. Brinell is used primarily on forgings and cast iron. The rebound test is used on large rolls. Vickers
Note 1: The Vickers and Knoop hardness numbers were originally defined in terms of the test force in kilogram-force (kgf) and the surface area or projected area in millimetres squared (mm 2).Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons (N). However, in practice, the most commonly used force .3.1.4 Brinell hardness test—an indentation hardness test using a verified machine to force an indenter (tungsten carbide ball with . 1 This test method is under the jurisdiction of ASTM Committee E28 on Mechanical Testing and is the direct responsibility of Subcommittee E28.06 on Indentation Hardness Testing.
