Note, when mass measurements are added to determine densities or unit weights, add the following. The straightness of the cylindrical surface can ast easily verified as well as flatness and verticality of end surfaces by the same dial gauge using the magnetic holder in the desired Not all dd4543 of this practice may be applicable in all circumstances.

However, when it has been determined by trial that this is not possible, prepare the rock specimen to the highest standard practicable and consider this to be the best effort and report it as such, with all appropriate size and dimensional measurements reported as in Section 6.

Cubical, rectangular, or other shapes are not covered by this practice. These practices specify e4543 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.
