ISO 22476-10 specifies the equipment, execution and reporting requirements of the weight sounding test.NOTE ISO 22476-10 fulfils the requirements for the weight sounding test as part of the geotechnical investigation and testing according to EN 1997?1 and EN 1997?2.ISO 22476-10 specifies the procedure for conducting a test with the weight sounding device in natural soils, made ground, and fill either on land or on water. ISO 22476-10 is applicable to the determination of the resistance of soil to the static load or the static load and the specified turning of the sounding point.ISO 22476-10 gives guidelines for the use of the weight sounding test to give a continuous soil profile and an indication of the layer sequence. The use includes the estimation of the density of cohesionless soils and the depth to very dense ground layers indicating the length of end-bearing piles.

ISO/TS 22476-10:2005 specifies laboratory test methods to establish the effective shear strength parameter for soils within the scope of the geotechnical investigations according to EN 1997-1 and EN 1997-2. The test method consists of placing the test specimen in the direct shear device, applying a pre-determined normal stress, providing for draining (and wetting if required) of the test specimen, or both, consolidating the specimen under normal stress, unlocking the frames that hold the specimen, and displacing one frame horizontally with respect to the other at a constant rate of shear-deformation and measuring the shearing force, and horizontal displacements as the specimen is sheared. Shearing is applied slowly enough to allow excess pore pressures to dissipate by drainage so that effective stresses are equal to total stresses. Direct shear tests are used in earthworks and foundation engineering for the determination of the effective shear strength of soils.
