Hardness testing of

Non-metallic materials

Back to overview

Hardness testing methods with lower test forces (low-load and micro methods such as Vickers and Knoop) are more likely to be used for testing the hardness of non-metallic materials, such as glass or ceramics, for example in the testing of lenses or ceramic gears.

Special standards have been defined for testing the hardness of carbon (e.g. electric motor components) and plastic (e.g. artificial hip joints) test parts. Carbon testing is conducted in compliance with DIN 51917, while EN ISO 2039 applies to plastic tests.

In order to save all available test data simply and clearly, the DuraJet G5 Rockwell tester can archive the data in a structured manner.

  • Standard test data management
  • Grouped test data management, e.g. for batches, departments, etc.

The preferred type of test data management is selected prior to testing. In the standard test data management system, all results are stored in a collective list.

If test data needs to be associated with individual users or user groups, specific components, batches or departments, then the grouped data management function should be used. All the determined test results are compiled in separate lists, allowing them to be clearly represented, exported or saved as a report. The groups created can be reloaded at any time and augmented with additional test results.

It is possible to integrate a hardness tester into a production line via a hardware interface. This enables external control of the machine.

  • External machine control
  • Option to connect foot switch


Both the DuraVision Semi-Automatic universal hardness tester and the DuraJet G5 Rockwell tester are equipped with an additional interface. This additional interface allows 100% tests to be conducted without having to remove test specimens from the production process.

Another option is to connect the available foot pedal to the interface, in order to use this for performing the clamping movement to fix a workpiece. The significantly simplifies handling in tests on large, unwieldy components.
