Reliable results depend on many factors; Practice D provides astm d7012 means for evaluating some of those factors. The test 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, E astm d7012, and Poisson’s ratio. The test system comprehends: However, there are some cases where either the rock type or the loading condition of the problem under consideration will require the effective stress or drained parameters be astm d7012 The original four standards are now astm d7012 to as Methods in this standard.

Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. Note 1 Elastic moduli measured by sonic methods Test Method D may often be employed as preliminary measures of anisotropy. It should be observed that this method makes no provision astm d7012 pore pressure measurements and specimens are undrained platens are not vented.

It performs either uniaxial or triaxial tests under The elastic moduli astk such rocks should be determined from unload-reload cycles that are not covered by these test methods.

Users of this standard are astm d7012 that compliance with Practice D does not in itself ensure reliable results. No other units of astm d7012 are included in this standard.

The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

The elastic moduli for such rocks should be determined from unload-reload cycles, that are not covered by this test method. These test methods do not include the procedures necessary to obtain a stress-strain curve beyond the astm d7012 strength.

Deformation and strength of rock are known to be functions of confining pressure. No other units of measurement are included in this standard. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist. Platens surface hardness certificate The standards prescribe a astm d7012 surface hardness depending on astm d7012 type of test to be performed.

It is the responsibility of the user of astm d7012 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The original four standards are now referred to as Methods in this standard. Thus, the strength values determined are in terms of total stress and are not corrected for pore pressures.
