A METHOD OF TESTING MATERIAL HARDNESS AND AN INDENTOR FOR CARRYING OUT THE METHOD

摘要

Method of testing material hardness. An indentor is caused to penetrate into the material by means of a force (P) acting on the indentor, measurement characterizing the hardness being made for at least two separate magnitudes of this force. The penetration depth (L) caused by the forces is measured for the separate magnitudes to determine that the penetration depth variation in relation to the force increase is constant. The invention also relates to an indentor for carrying out the abovementioned material test.
