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.

Rock specimen grinding machine Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. 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.

However, the requirements in the specific test standards in 2.

Note, when mass measurements are added to determine densities or unit weights, add the following. The values stated c4543 each system may not be exact equivalents; therefore, each system shall be used independently of the other.

For these and other rock types which are difficult to prepare, all reasonable efforts shall be made to prepare a sample in accordance with this practice. Specimen grinding machine The machine is used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. 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.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. Rock sample verification apparatus Used to verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia.

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. Not all aspects 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.

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 magnetic holder in the desired Specimen grinding machine Used to grind and polish concrete specimens, natural stones, ceramic materials, etc.

Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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.
