ISO/TS 17892-8:2004 specifies the test method for the determination of the compressive strength of a cylindrical, water-saturated specimen of undisturbed or remoulded cohesive soil when first subjected to an isotropic stress without allowing any drainage from the specimen, and thereafter sheared under undrained conditions within the scope of the geotechnical investigations according to prEN 1997-1 and -2. NOTE "Water-saturated" refers to the in-situ condition. The material tested need not necessarily be saturated at all stages during the laboratory testing.
