The disclosure is directed to a method and apparatus for measuring the cohesive forces in a tablet formed from compressed powders and is made up of a split die which has a cavity for the powders to be compressed, a cutting blade disposed between the two portions of the split die and extending outside the die, a cantilever beam connected at its free end to the extending end of the blade, reciprocating means connected to the other end of the cantilever beam to draw the blade through a compressed powder, while the compressed powder is still in the die cavity, and strain gauges connected to the cantilever beam to measure the amount of bending imparted to the cantilever beam by the resistance of the compressed powder to the movement of the blade. The cohesion forces thus determined may be used to predict the tableting characteristics of the material.
