This European standard specifies requirements for indirect investigations of soil by Dynamic Probing within the scope of the geotechnical investigations according to ENV 1997. This European standard covers the determination of the resistance of sols and soft rocks in situ to the dynamic penetration of acone. A hammer of a given mass and given falling height is used to drive the done. The penetration resistance is defined as the number of blows required to drive the penetrometer over a defined distance. A continuous record is provided with respect to depth but no samples are recovered. Four procedures are included, covering a wide range of specific work per blow: - Dynamic probing light (DPL): test representing the lower end of the mass range of dynamic equipment; - Dynamic probing medium (DPM): test representing the medium mass range of dynamic equipment; - Dynamic probing Heavy (DPH): test representing the medium to very heavy mass range of dynamic equipment; - Dynamic probing super heavy (DPSH): test representing the upper end of the mass range of dynamic equipment.
