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.
This test is suitable for almost all metals and to some degree for plastics. The 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:
The Rockwell hardness is determined by the application of a preliminary test force (minor load or preload), followed by an additional load (major load) to reach the total required test load, finally returning to the same preliminary test force (minor load). The first minor load provides the zero or reference position. The major load is applied and held for a predetermined amount of time (dwell time) to allow for elastic recovery. Then the major load is removed, while still maintaining the minor load to establish the change from zero or reference position in determining a Rockwell hardness value.
INNOVATEST offers various dedicated Rockwell hardness testers that are Load Cell Closed Loop machines developed, designed and endurance tested at our R&D facilities.
In addition, all electronic boards and high-tech components are manufactured internally allowing the highest level of manufacturing quality control in our industry. View all rockwell models here.
