Test Method Title
Standard Practices for Preparing Rock Core Specimens and Determining Dimensional and Shape Tolerances
Description of Test
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.
Preferred Test Sample Size
Rock core specimens
Number of Test Specimens
Test Specimen Size
Right circular cylinder, with diameter of at least 1 7/8 in and a length to diameter ratio of 2 to 2.5:1
