It performs either uniaxial or triaxial tests under Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. Temperature Variation— Applies to any of the methods and allows for testing at temperatures above or below room temperature. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing.

Hoek cells and sample extruder The Hoek triaxial cells are offered in five models of different size; each one consists of the following: Rock mechanics – Uniaxial and triaxial test systems: The 2 consoles are operated independently and the 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.

Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist. 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 test method does not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength. Active view current version of standard.

The test system comprehends: When required, the hardness verification is performed with certified instruments.

These methods make no provision for pore pressure measurements and specimens are undrained platens are not vented. Elastic moduli x7012 by sonic methods Test Method D may often be employed as preliminary measures of anisotropy.

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, Eand Poisson’s ratio.

It is desirable to conduct tests in the plane of foliation, cleavage or bedding and at right angles to it to determine the degree of anisotropy.

Strain is not typically measured; therefore a stress-strain curve is not produced.
