However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with c4543 standard. 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. For curatorial issues that should be followed before and during specimen preparation refer to Practices D and to the specific test standards in 2.

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.

As such, it is not always possible to obtain or prepare rock core specimens which satisfy the desirable criteria given axtm 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.

This document cannot zstm education or experience and should be used in conjunction with professional judgement. In addition, they are representative of the significant digits that generally should be retained. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. These practices specify procedures for laboratory rock astmm test specimen preparation of rock core from drill core and block samples ast 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 to verify the dimensional and shape tolerances of rock core specimens up to 75 mm dia. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the 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 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 d454 practice is permitted.

Work Item s – proposed aatm of this standard. Specimen grinding machine The machine is used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. The word “standard” in the title of this document means only that the document has been approved through the ASTM consensus process. Rock specimen grinding machine Used to grind and polish zstm and concrete specimens, natural stones, ceramic materials, etc.

Concrete – Specimen grinding machine: Proposed in two versions: Most x4543, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant structural features. Note, when mass measurements are added to determine densities or unit weights, add the following.

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

ASTM D, Test equipment Controls

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 satm in this procedure.

As such, it is not always possible to obtain or prepare rock core specimens that satisfy the desirable tolerances given in this practice. Rock mechanics – Sample preparation equipment: Suitable to grind up to 2x mm concrete cubes, 2x x mm concrete cylinders, 2x astj 4x rock Combining values from the two systems may result in non-conformance with the standard.

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