The H-60 is a field inspection vane tester used to provide a rapid check of the stability of foundations, excavations and trenches in clay. It enables quick and easy determination of the undrained shear.
The field vane shear test (FVST) is the most commonly used method for measuring the undrained shear strength of soft to stiff clays. For this reason, a preliminary investigation of soft clays with a hand-held vane tester is both economic and fully relevant. It also has good repeatability and is quick in providing valuable information for the planning of more detailed surveys.
