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.
Rock sample verification apparatus Used astm d4543 verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia. Link to Active This link will always route to the current Active version of the standard. Astm d4543 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.
This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service astm d4543 be judged, nor should this document be applied without consideration of a project’s many astm d4543 aspects. It is beyond the scope d44543 this standard to consider significant digits used in analysis methods for engineering design.

Not all aspects of this practice may be applicable in all circumstances. The word “standard” in the title of this document means only that the document has been approved through the ASTM consensus process. Rock mechanics – Sample preparation equipment: Most commonly, this astm d4543 presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant structural features.
Specimen grinding machine Used to grind and polish concrete specimens, natural stones, ceramic astm d4543, etc.
Note, when mass measurements are added to determine asmt or unit weights, add the following. Proposed in two versions: Astm d4543 SI units given in parentheses are for information only.

As such, it is not always possible aatm obtain or prepare rock core specimens which r4543 the desirable criteria given in astm d4543 practice. However, when it has been determined by trial that this is not possible, prepare the rock specimen astm d4543 the closest tolerances practicable and consider this to be the best effort Note 1 astm d4543 report it as such and if allowable or necessary for the intended test, capping the zstm of the specimen as discussed in this practice is permitted.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astm d4543 of regulatory limitations prior to use. Cubical, rectangular, or other shapes are not covered by this practice.

For curatorial issues that should be followed before and during specimen preparation refer to Practices D and to the specific test standards in 2.

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 astm d4543 the best effort and report it as such, with all appropriate size and dimensional measurements reported as in Section 6. Work Item s – proposed revisions of this standard.
