Work Item s – proposed revisions of this standard. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. Note, when mass measurements are added to d453 densities or unit weights, add the following.

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 should this document be applied without consideration of a project’s many unique aspects. 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.

The values stated in each system may not be exact equivalents; therefore, e4543 system shall be used independently of the other.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 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.

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.

Suitable to grind up to 2x mm concrete cubes, 2x x mm concrete cylinders, 2x or 4x rock 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 Follow us YouTube LinkedIn. 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.

This document cannot replace education or experience and should be used in conjunction with professional judgement. Cubical, rectangular, or other shapes are not covered by this practice.

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 should this document be applied without consideration of a project’s many unique aspects. As such, it is not always possible to obtain or prepare rock core specimens which satisfy the desirable criteria 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.

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 d44543 procedure.

Not all aspects of this practice may be applicable in all circumstances.

Not all aspects of this practice qstm be applicable in all circumstances. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

Proposed in two versions: As such, it is not always possible to obtain or prepare rock core specimens that satisfy the desirable tolerances given in this practice. 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.

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 this practice is permitted.

Most commonly, this situation presents itself with weaker, more porous, and poorly cemented rock types and rock types containing significant structural features. Formerly under the jurisdiction of Committee D18 on Soil and Rock, this standard was withdrawn in July in accordance with section 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.
