In the Rockwell hardness test, the user is faced with the challenge of maintaining the minimum distances between the indentations according to the standard.
The minimum distances depend on the indentation diagonal, which is not measured during the Rockwell test.
It is therefore inconvenient for the user to specify the minimum distances himself.
The MPA NRW in Dortmund has determined a formal estimation of the minimum distances in the course of many measurements and published it with the information sheet 01-2017.
For simple use in everyday life, we at Pro-K have implemented the formulas in a calculator on our homepage.
