scope:

This Part of ISO 22476 is applicable to pressuremeter tests using cylindrical flexible probes placed in pre-existent boreholes using testing procedures other than the Menard procedure. For pressuremeter tests following the Menard procedure refer to ISO 22476-4. NOTE - A high pressure flexible pressuremeter probe which contains transducers for the measurement of radial displacements is also known as flexible dilatometer or high-pressure dilatometer This standard applies to tests performed in any kind of grounds, starting from soils, treated or untreated fills, hard soils and soft rocks, up to hard and very hard rocks, either on land or offshore. The parameters derived from this test may include stiffness, strength, initial in-situ stress state and consolidation properties.
