Description / Abstract:

(Footnote *)

This test method covers the creep behavior of intact cylindrical soft 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. Soft rocks include such materials as salt and potash, which often exhibit very large strain at failure.

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

The method used to specifiy 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.

The values stated SI units are to be regarded as the standard.

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.
