NF EN ISO 22476-5, P94-521-5 (04/2023)

This document applies to pressure gauge testing using flexible cylindrical probes placed in pre-existing boreholes, carried out using procedures other than the Ménard procedure. Pressure gauge tests according to the Ménard procedure are available in ISO 22476-4. NOTE A high-pressure flexible pressuremeter probe which includes sensors intended for measuring radial displacements is also called a flexible dilatometer or high-pressure dilatometer. This document applies to tests carried out in any type of terrain, from treated or untreated soils, embankments, hard soils and soft rocks, to hard and very hard rocks, on land or at sea. Parameters deduced from this test may include modulus, strength, initial in situ stress state and consolidation properties.
