Methods with static force application are predominantly used for the hardness testing of metals that can be distinguished according to the following criteria:
- form of the indenter (ball, pyramid or cone)
- indenter material (hardened steel, carbide metal or diamond)
- size of the test force applied to a test specimen
- method of evaluation: measurement of the penetration depth (depth measurement method) or size of the indentation (optical measuring method) caused by the indenter.
