Scope

1.1 This test method covers the determination of the direct tensile strength of the rock substance or discontinuities normal to the longitudinal axis of intact, isotropic cylindrical rock specimens at room temperature. 1.2 Non-isotropic or even transversely isotropic specimens are not covered by this standard. 1.3 Cylindrical rock specimens can be drill core from the field or rock blocks transported to the laboratory and drill core specimen obtained there. 1.4 Specimen shapes other than cylindrical specimens, such as dog bone-shaped, are not covered by this standard. 1.5 Test specimens may be tested under constant load or deformation rate. 1.6 The values stated in SI units are to be regarded as standard. The values provided in parenthesis are for information only. 1.7 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 unless superseded by this standard. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
