Rock
Sample preparation
The dimensional, shape and surface tolerances of rock core specimens are all important when measuring intact rock strength. Rock cores are cut with a wet saw, then surface ground with special equipment to the tolerances set forth in this standard. Several parameters are measured and compared to the tolerances: straightness, flatness, parallelism & perpendicularity.
