Methods of testing rocks for engineering purposes, Method 4.3.2: Rock strength tests — Determination of the deformability of rock materials and uniaxial compressive strength — Rock strength less than 50 MPa
AS 4133.4.3.2:2022 sets out the method for determining the uniaxial compressive strength, the stress-strain characteristics, Young’s modulus and Poisson’s ratio of a rock sample in compression in the form of specimens of regular geometry of strength less than 50 MPa. The test is intended for strength classification and characterization of intact rock.
