Rockwell hardness testing method
The Rockwell test method, as defined in ISO 6508 & ASTM E-18, 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.
How is a Rockwell hardness test determined?
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 refence position in determining a Rockwell hardness value.
The NEXUS, VERZUS, NEMESIS and Fenix 200CL series, our dedicated Rockwell testers, 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.
In the early stage of your interest in our testers, our sales team will gather the information to offer a product adapted to your individual requirements and testing needs. We welcome requests for customized solutions whether it be software and/or hardware to best suit our testers for your needs. Our team takes great pride in working with your team to develop and supply the right configuration of hardness tester for your application.
