Geotechnical investigation and testing - Laboratory testing of soil - Part 7: Unconfined compression test (ISO 17892-7:2017); German version EN ISO 17892-7:2018
This international standard specifies a method for the unconfined compression test. This international standard is applicable to the determination of the unconfined compressive strength for a homogeneous specimen of undisturbed, re-compacted, remoulded or reconstituted soil under compression loading within the scope of geotechnical investigations. This test method is useful to estimate the undrained shear strength of soil. It should be noted that drainage is not prevented during this test. The estimated value for undrained shear strength is therefore only valid for soils of low permeability, which behave sufficiently undrained during the test.
