Since it is widely used in practice, a uniform test method is needed for data to be comparable.

Also, by testing across different diametrical directions, possible variations in tensile strength for anisotropic rocks can be determined. Reporting of test f3967 in units other than SI shall not be regarded as nonconformance with this test method. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

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. In addition, they are representative of the significant digits that generally should be retained. The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and d33967 not considered standard.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to asmt commensurate with these considerations.

Rock testing Back to Results Print. This test is a simpler and less expensive alternative to the direct tensile test method. This test determines the splitting tensile strength of rock by diametral line compression of a disk of rock. However, the direct tensile test is difficult and expensive for routine application. The diameter shall be at least 10 times greater than the largest mineral grain constituent. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

These include combinations of compressive and tensile stress fields. The splitting tensile test appears to offer a desirable alternative, because it is much simpler and inexpensive.

Under such conditions, the tensile strength should be obtained with the presence of compressive stresses to be representative of the field conditions.

Historical Version s – view previous versions of standard. A uniform test is also needed to asstm sure that the disk specimens break diametrically due to tensile stresses perpendicular to the loading diameter.

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

Furthermore, engineers involved in rock mechanics design usually deal with complicated stress fields, including various combinations of compressive and tensile stress fields.

Circular disk with a thickness-to-diameter ratio between 0. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
