The diameter shall be at least 10 times greater than the largest mineral grain constituent. 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.

Enough samples to represent a valid average of the type of rock under consideration; however the standard recommends 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 aatm data to be commensurate with these considerations.

A uniform test is also needed to make sure that the disk specimens break diametrically due to tensile stresses perpendicular to the loading diameter. Circular disk with a thickness-to-diameter ratio between 0.

ASTM D – 16 Standard Test Method for Splitting Tensile Strength of Intact Rock Core Specimens

In addition, they are representative of the significant digits that generally should be retained. Link to Active This link will always route to the current Active version of the standard.

This test determines the splitting tensile strength of rock by diametral line compression of a disk of rock. Since it is widely used in practice, a uniform test method is needed for data to be comparable. atsm

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. 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. Users of this standard are cautioned that compliance with Practice D does not in itself assure asm results. Compression testing, indirect tensile strength, loading tests, rock, splitting tensile strength, tension properties, Brazilian tensile strength.

Compression tests

However, the direct tensile test is difficult and expensive for routine application. For more information, contact: Under such conditions, the tensile strength should be obtained with the presence of compressive stresses to be representative of the field conditions.

Furthermore, engineers involved in rock mechanics design usually deal with complicated stress fields, including various x3967 of compressive and tensile stress fields. This test is a simpler and less expensive alternative to the direct tensile test method. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

Reporting of test results 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 asttm subject standard but are not provided as part of the standard.

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.

Rock testing Lab Services: Under these conditions, tensile strength should d367 obtained with the presence of compressive c3967 as is what occurs in this test to be representative of the field conditions.
