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.

Little or no specimen preparation is needed and can therefore be tested shortly after being obtained and any influence of moisture condition on the test data minimized.

C5731 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.

Mechanical properties

This is an index test and is intended to be used to classify rock strength. The specifics of the point load test program need to be developed prior to testing and possibly even before sampling. 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.

However, the results can be highly influenced by how the specimen is treated from the time it is obtained until the time it is tested. The quality of the result produced zstm this standard is dependent upon the competence of the personnel performing it, and the suitability of the equipment and facilities used.

How one applies the results obtained using this standard is beyond its scope. It is the responsibility of the user of this standard to zstm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Such data can be used to make timely and more informed decisions during the exploration astj and more efficient and cost effective selection of samples for more precise and expensive laboratory tests.

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.

ASTM D – 02 Standard Test Method for Determination of the Point Load Strength Index of Rock

This is an index test and is intended to be used to classify rock strength. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

In addition, they are representative of the significant digits that generally should be retained. 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. 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 beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. 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.

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. 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 c5731 this test method.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and sampling.
