Annotation of standard text ČSN EN ISO 22476-9 (721004):

This document deals with the equipment requirements, execution and reporting of field vane tests for the measurement of peak and remoulded vane shear strength together with the sensitivity of fine-grained soils. In addition, post-peak shear strength behaviour can be evaluated. Two types of field vane test are described: the ordinary field vane test (FVT) and the fast field vane test (FVT-F).
The uncertainties of the vane test result are described in Annex D.
NOTE 1 - This document fulfils the requirements for field vane tests as part of the geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.
NOTE 2 - This document covers onshore and nearshore field vane testing
