Cubical, rectangular, or other shapes are not covered by this practice. 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.
Not all aspects of d44543 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.
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. Maintenance Spares Technical trainings Warranty Academy. In addition, they are representative of the significant digits that generally should be retained.
This ASTM standard is not aztm 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.
Active Risk Management
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. Formerly under the jurisdiction of Committee D18 on D45543 and Rock, this standard was withdrawn in July in accordance with section The straightness of the cylindrical surface can be easily verified as well as flatness and verticality of end surfaces by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 atm Follow us YouTube LinkedIn.
This document cannot replace education or experience and should be used in conjunction with professional judgement. Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant or weak or both structural features. Concrete – Specimen grinding machine: The word “standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

Link to Active This link will always route to the current Active version of the standard. Rock sample verification apparatus Used to verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia.
Rock mechanics – Sample preparation equipment: Specimen grinding machine The machine is 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. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. For curatorial issues refer to Practices D Combining values from the two systems may result in non-conformance with the standard.
Asym 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. As such, it is not always possible to obtain or prepare rock core specimens which satisfy the desirable criteria given in this practice.
