This document cannot replace education or experience and should be used in conjunction with professional judgement.
Most commonly, this situation ast, itself with weaker, more porous, and poorly cemented rock types and rock types containing significant structural features.
Rock specimen grinding machine Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. However, some of the information contained with in this practice and in standard Test Method C may still be of use to preparing other test specimen shapes.
As such, it is not always possible to obtain or prepare rock core specimens that satisfy the desirable tolerances given in this practice. 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.
This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Best effort in surface preparation refers to the use of a well-maintained surface grinder, lathe or lapping machine by an experienced operator in which a reasonable number of attempts has been made to meet the tolerances required in this procedure.
For these and other rock types which are difficult to prepare, all reasonable efforts shall be made to prepare a specimen in accordance with this practice and for the intended test procedure. Combining values from the two systems may result in non-conformance with the standard.

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.
Suitable to grind up to 2x mm concrete cubes, 2x x mm concrete cylinders, 2x or 4x rock Not all aspects of this practice may asttm applicable in all circumstances.
