Scope

This standard is applicable to the determination of the strength and deformation characteristics of cylindrical coal and rock specimens under three-dimensional stress conditions in the axisymmetric stress combination mode (σ1>σ2=σ3). From this test, the data required to determine the strength envelope can be obtained, and the internal friction angle and cohesion can be calculated.
