Geotechnical investigation and testing - Field testing - Part 16: Borehole shear test (ISO/FDIS 22476‑16:2023)

General information

50.60     Dec 1, 2023



European Norm




This standard describes the test method covering the procedure for drilling the borehole, inserting the probe, and performing the test in soils and weak rock by axial shearing of the borehole wall. It does not include high pressure testing in hard rock. The test works best in sands, silts, clays and weak rocks, which will maintain open test cavity or which can be held open with drilling fluid.
NOTE This document is intended to be used in conjunction with EN 1997-2. EN 1997-2 defines the way ground investigation has to be done to define a reliable ground model including resistance of soils and rocks.
