Such data can be used to make timely and more informed decisions during the exploration phases and more efficient and cost effective selection of samples for more precise and d731 laboratory tests. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and sampling.

Point Load Tester

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. The quality of the result produced by this standard is dependent upon the competence of asgm personnel performing it, and the suitability of the equipment and facilities used.

The test results should not be used for design or analytical purposes. The specifics of the point load test program need to be developed prior to testing and possibly even before sampling. This is an index test and is intended to be used to classify rock strength. Such specifics would be dependent on the intended use of the data, as well as possible budgetary constraints and possible other factors, which are outside the scope of this test method.

Therefore, it may be necessary to handle specimens in accordance with Practice D and to document moisture conditions in some manner in the data collection. Link to Active This link will always route to the current Active version of the standard. Historical Version s – view previous versions of standard. This is an index test and is intended to be used to classify rock strength.

Reliable dd5731 depend on many factors; Practice D provides a means of evaluating some of those factors.

The test d531 typically used in the field because the testing machine is portable, little or minimal specimen preparation is required, and specimens can be tested within a short time frame of being collected.

The specifics of the point load test program need to be developed prior to testing and possibly even before sampling.

In addition, they are representative of the significant digits that generally should be retained. 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 reliable results. Such specifics would be dependent on the intended use of the data, as well as possible budgetary constraints and possible other factors, which are outside the scope of this test method.

However, it is a time-consuming and expensive test that requires significant specimen preparation and the results may not be available for a long time after the samples are collected. The test is typically used in the field because the testing machine is portable, little or minimal specimen preparation is required, and specimens can be tested within a short time frame of being collected.

It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. However, the results can be highly d57731 by how the specimen is treated from the time it is obtained until the time it is tested.
