Application Summary AI generated

This standard specifies the test procedures for determining the point load strength index of coal and rock samples. It is applied in the mining and geotechnical engineering industries to evaluate rock strength for excavation design, roof support planning, and stability analysis of underground workings. The method provides a rapid, field-based alternative to uniaxial compressive strength testing for classifying rock mass quality.
