Zusammenfassung:	It is the object of the invention to improve the accuracy of hardness testing whilst avoiding a high testing cost. In the invention, the penetration work of the testing body up to the attainment of a predetermined penetration depth is measured and is used as a value for the hardness of the specimen. The method can be used within a region which lies between too soft and too hard materials, in the case of all specimens whose hardness is intended to be measured.
