According to the dynamic Leeb principle, hardness value is derived from the energy loss of a defined impact body after impacting on a metal sample, similar to the Shore scleroscope. It is available for people to get more than 30 professional conversion tables. While in the traditional static tests the test force is applied uniformly with increasing magnitude, dynamic testing methods apply an gardness load.
