These practices specify procedures for laboratory rock core test specimen preparation of rock core from drill core and block samples for strength and deformation testing and for determining the conformance of the test specimen dimensions with tolerances established by this practice.

Rock sample verification apparatus Used astm d4543 verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia.
