It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. The original four standards are now referred to as Methods in this standard.
ASTM D, Test equipment Controls
Rock mechanics – Uniaxial and triaxial test systems: These test methods do not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength. Historical Version s – view previous versions of standard.
The v7012 method specifies the apparatus, instrumentation, and procedures for determining the stress-axial strain and the stress-lateral strain curves, as well as Young’s modulus, Eand Poisson’s ratio. Rock mechanics – Highly advanced rock testing systems: Thus, the strength values determined are in terms of total stress and are not corrected for pore pressures. Maintenance Spares Technical trainings Warranty Academy.
Therefore, laboratory values for intact specimens must be employed with proper judgment in engineering applications.
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. Thus the strength values determined are in terms of total stress, that is, are not corrected for pore pressures. Rock mechanics – Accessories for uniaxial and triaxial tests: The quality of the result produced by this standard is dependent on the competence of the personnel d70112 it, and the suitability of the equipment and facilities used.
Semi-automatic Uniaxial and Triaxial test system. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
No other units of measurement are included in this standard. These methods x7012 no provision for pore pressure measurements and specimens are undrained platens are not vented. Deformation and strength of rock are known to be functions of confining pressure.
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.
Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Elastic moduli measured by satm methods Test Method D may often be employed as a preliminary measure of anisotropy.
Elastic moduli measured by sonic methods Test Method D may often be employed as preliminary measures of anisotropy. The tests provide data in determining the strength of rock, namely: Referenced Documents d70012 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This test method does not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength.
ASTM D7012 – 14e1
The Rock core should have a diameter from Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. In addition, they are representative of the significant digits that generally should be retained.
