Test that allows to determine the hardness of the material to be penetrated. It consists of the penetration of a sphere (soft material) or diamond cone (hard material) through a load that is carried out in two successive stages.

The hardness value is determined by the difference between the depth of penetration of both:

E= H – HO

(H = the fundamental load and H0 = the preliminary load.)
