(Footnote *)

This test method covers the creep behavior of intact cylindrical hard rock core specimens in uniaxial compression. It specifies the apparatus, instrumentation, and procedures for determining the strain as a function of time under sustained load. Hard rocks are those with maximum strain at failure of less than 2 %.

NOTE 1 - Most hard brittle rocks fail in uniaxial compression at strain levels of less than 2 %.

All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.

The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in design or other uses, or both. How one applies the results obtained using this standard is beyond its scope.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
