Abstract
A slow strain rate shear strength tester for a tablet of compressed pharmaceutical powders, which apparatus includes a ram assembly having a reciprocal ram horizontally slidably supported on a housing. The ram projects outwardly of the housing and mounts a compression member on the free end thereof. A head arrangement is removably mounted on a pair of brackets which project from the end of the housing. The head arrangement has opposed holding members which cooperate to define a notch for accommodating a compact therein in position for compression by the ram.
