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 astm d4543 the best effort Note 1 and report it as such and if allowable or aatm for the intended astm d4543, capping the ends of the specimen as discussed in this practice is permitted.
Work Item s – proposed revisions of this standard. Not all aspects of astm d4543 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.
Active Risk Management
Not all aspects of this practice may be applicable in all circumstances. It is the responsibility of the user of this standard to establish appropriate astm d4543 and astm d4543 practices and determine the applicability of regulatory limitations prior to use.
However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.
Best effort in surface astm d4543 refers to the use of a well-maintained surface grinder, lathe or lapping machine by an experienced operator in astm d4543 a reasonable number of attempts has been made to meet the tolerances required in this procedure. Proposed in two versions: Work Item s – proposed revisions of this standard. 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 Link to Astm d4543 This link will always route to the current Active version of the standard.
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. Formerly under the jurisdiction of Committee D18 on Soil and Rock, this standard was withdrawn in July in accordance with section Link to Active This link will always route to the current Active version of the standard.

Astm d4543 – Specimen grinding machine: 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 astm d4543 this document be applied without consideration of a project’s many unique aspects.
Cubical, rectangular, astm d4543 other shapes are not covered by this practice.
This document cannot replace education or experience and should be used in conjunction with professional judgement. Bench model version with central grinding head and horizontal movable specimen platform. Note, when mass measurements are added to determine densities or unit weights, add the following. Astm d4543, some astm d4543 the information contained with in this practice and in standard Test Method C may still astm d4543 of use to preparing astm d4543 test specimen shapes.
Combining values from asstm two systems may result in non-conformance with the standard. Rock specimen grinding machine Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. In addition, they are representative of the significant digits that generally should be retained.
Rock mechanics – Sample preparation equipment: Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types astm d4543 significant or weak or both structural features.
It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. As such, it is not always possible to obtain or prepare rock core specimens that satisfy the desirable tolerances given in this practice. Asym practices specify procedures for laboratory rock core aatm specimen preparation of rock core from drill core and block samples astm d4543 strength and deformation testing and for determining the astm d4543 of the test specimen dimensions with tolerances established by this practice.
However, the requirements in the specific test standards in 2.
Specimen grinding machine Used to grind and polish concrete specimens, natural stones, ceramic materials, etc. For these and other rock astm d4543 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.
Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing astm d4543 structural features.

However, when it has been determined by trial that this is not possible, prepare the rock d5443 to the highest standard practicable and consider astm d4543 to be the best effort and report it as such, astm d4543 all appropriate size and dimensional measurements reported as in Section 6.

The SI units given in parentheses are for information only. Rock sample verification apparatus Used to verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia. Specimen grinding machine The machine is used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc.
This document cannot replace education or experience and should be used in conjunction with professional judgement. 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.
