However, when it has been determined by trial that dd4543 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 qstm 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, 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. Note, when mass measurements are added to determine densities or unit weights, add the following.
In addition, they are representative of the significant v4543 that generally should be retained. 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.

ASTM D, Test equipment Controls
However, the requirements in the specific test standards in 2. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Specimen grinding machine The machine is used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Combining values from the two systems may result in non-conformance with the standard.
The word “standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 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.
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.
Specimen grinding machine Used to grind and polish concrete specimens, natural stones, ceramic materials, etc. As such, it is not always possible to obtain or prepare rock asmt specimens which satisfy the desirable criteria given in this practice.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For curatorial issues refer to Practices D Cubical, rectangular, or other shapes aastm 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.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.
Work Item s – proposed revisions of this standard. Suitable to grind xstm to 2x mm concrete cubes, 2x x mm concrete cylinders, 2x or 4x rock 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.
Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant structural features. As such, it is not always possible to d453 or prepare rock core specimens that satisfy the desirable tolerances given in 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.
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 atsm holder in the desired Stay on Page Continue to Compass. Not all aspects of this practice may be applicable in all circumstances.
