Rockwell Hardness Testing Machines

The Rockwell hardness tester uses the method as defined in ISO 6508 & ASTM E18, which is the most commonly used method around the world to determine a material’s hardness and is suitable for almost all metals and to some degree for plastics. Rockwell test measures the permanent depth of indentation produced by a specified force/load on a specified indenter. The Rockwell test requires the least amount of sample prep making it the quicker and easier hardness test to perform across many industries around the globe. The main advantage of Rockwell hardness testing is its speed of testing and its ability to display hardness values directly after penetrating the material.
