Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

Also, by testing across different diametrical directions, possible variations in tensile strength for anisotropic rocks can be determined. Enough samples to represent a valid average of the type of rock under consideration; however the standard recommends For more information, contact: The diameter shall be at least 10 times greater than the largest mineral grain constituent.

The 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. This test is a simpler and less expensive alternative to the direct tensile test method.

Under these conditions, tensile strength should be obtained with the presence of compressive stresses as is what occurs in this test to be representative of the field conditions. 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 r3967 practice to increase or reduce significant digits of reported data to be commensurate with these considerations.

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

However, the direct tensile test is difficult and expensive for routine application. Compression testing, indirect tensile strength, satm tests, rock, splitting tensile strength, tension properties, Brazilian tensile strength.

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.

A uniform d39677 is also needed to make sure that the disk specimens break diametrically due to tensile stresses perpendicular to the loading diameter. Since it is widely used in practice, a uniform test method is needed for data to be comparable.

Under such conditions, the tensile strength should be obtained with the presence of compressive stresses to be representative of the field conditions. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. This test determines the splitting tensile strength of rock by diametral line compression of a disk of rock.

Active Risk Management

Circular d39667 with a thickness-to-diameter ratio between 0. Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.

The splitting tensile test appears to offer a desirable alternative, because it is much simpler and inexpensive. These include combinations of compressive and tensile stress fields. Historical Version s – view previous versions of standard. Request Quote Client Login.
