    For different types of rocks could provide wrong results. On the other hand the potential of the point load test has not yet been fully assessed for anisotropic rocks. In this paper new empirical relationships are developed between uniaxial compressive strength and point load index Is50 in anisotropic rocks particularly in schists and shales.
