heal.abstract	The advantages and limitations of point load test have been extensively discussed in literature. Although, the point load strength can be representative of the uniaxial strength of isotropic rocks, it can be misleading in the case of anisotropic rocks due to the presence of foliation or bedding planes. The foliated nature of most metamorphic rocks suggests a directional variation in their point load strength. The paper describes results from tests performed on anisotropic rocks, according to the suggested method by ISRM but also using alternative loading directions in the diametral test. The strength anisotropy index Ia(50) was determined for these rocks and has been compared to the degree of strength anisotropy as measured in specimens tested under uniaxial compression. Finally, a new anisotropy index is proposed and suggestions are made in using point load test for the classification of rock strength anisotropy. © 2006 Taylor & Francis Group.	en
