ISO 17892-8:2018 specifies a method for unconsolidated undrained triaxial compression tests. ISO 17892-8:2018 is applicable to the laboratory determination of undrained triaxial shear strength under compression loading within the scope of geotechnical investigations. The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic stress under undrained conditions and thereafter is sheared under undrained conditions. The test allows the determination of shear strength and stress-strain relationships in terms of total stresses. Non-standard procedures such as tests with the measurement of pore pressure or tests with filter drains are not covered in this document. NOTE – This document fulfils the requirements of unconsolidated undrained triaxial compression tests for geotechnical investigation and testing in accordance with EN 1997‑1 and EN 1997‑2.
