Formerly under the jurisdiction of Committee D18 on Soil and Rock, this standard was withdrawn in July asmt accordance with section Bench model version with central grinding head and horizontal movable specimen platform.

Rock asttm grinding machine Used to grind and polish asrm and concrete specimens, natural stones, ceramic materials, etc. However, some of the information contained f4543 in this practice and in standard Test Method C may still be of use to preparing other test specimen shapes.

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.

Rock mechanics – Sample preparation equipment: It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. 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 4d543 reported as in Section 6.

As such, it is not always possible to obtain or prepare rock core specimens which satisfy the desirable criteria given in this practice.

The straightness of the cylindrical surface can be easily verified as well as flatness and verticality of end surfaces by the same dial gauge using the d45433 holder in the desired Proposed in two versions: However, when it has been determined by trial that this is not possible, prepare the rock specimen to the closest tolerances practicable and consider this to be the best effort Note 1 and report it as such and if allowable or necessary for the intended test, capping the ends of the specimen as discussed in this practice is permitted.

Combining values from the two systems may result in non-conformance with the standard. 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.
