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. A d367 test is also needed to make sure that the disk 3d967 break diametrically due to tensile stresses perpendicular to the loading diameter.

In rock mechanics design, complicated stress fields are often encountered. It is the responsibility of the user d967 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

Active Risk Management

Also, by testing across different diametrical directions, possible variations in tensile strength for anisotropic asgm can be determined. The splitting tensile test appears to offer a desirable alternative, because it is much simpler and inexpensive. This test determines the splitting tensile strength of rock by diametral line compression of a disk of rock. This test is a simpler and less expensive alternative to the direct tensile test method.

Under such conditions, the tensile strength should be obtained with the presence of compressive x3967 to be representative of the field conditions. Historical Version s – view previous versions of standard.

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

The diameter shall be at least 10 times greater than the largest mineral grain constituent. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Furthermore, engineers involved in rock mechanics dd3967 usually deal with complicated stress fields, including various combinations of compressive and tensile stress fields. These include combinations of compressive and tensile stress fields.


ASTM D, Test equipment Controls

However, the direct tensile test is difficult and expensive for routine application. Enough samples to represent a valid average of the type of rock under consideration; however the standard recommends 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.

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 satm user’s objectives; and it is 3d967 practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
