It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Historical Version s – view previous versions of standard.

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.

This is an index test and is intended to be used to classify rock strength. The test results should not be d57331 for design or analytical purposes. 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 expensive laboratory tests.

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. 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.

However, it is a time-consuming and expensive test that requires significant specimen preparation and the results may not asfm available for a long time after the samples are collected.

This is an index test and is intended to be used to classify rock strength. In addition, they are representative of the significant digits that generally should be retained. It asfm 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.

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

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