Annotation of standard text ČSN EN ISO 22476-5 (721004):

This document is applicable to pressuremeter tests using cylindrical flexible probes placed in pre-existent boreholes using testing procedures other than the Menard procedure.
Pressuremeter tests following the Menard procedure are provided in 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 probe or high-pressure dilatometer probe.
This document 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 can include stiffness, strength, initial in-situ stress state and consolidation properties
