BS EN ISO 17892-7:2018 specifies a method for the unconfined compression test.This document 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 is 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.Cross References:ISO 17892-1ISO 17892-2ISO 14688-1EN 1997-1ISO 7500-1EN 1997-2All current amendments available at time of purchase are included with the purchase of this document.
