DP tests

Pagani Geotechnical Equipment penetrometers allow DP dynamic penetrometric tests to be carried out according to International Standard Procedures.

The DP test consists of driving a conical bit into the ground and measuring the number of strokes necessary to do so.

DP dynamic penetrometric tests are very common, and used by geologists and geotechnicians since they are extremely simple, cheap and quick to perform.

The average energy efficiency of 78% (proportion of energy transmitted to rods) allows the N20 value to be standardised with the data of other in-situ tests, mainly NSPT.

Pagani Geotechnical Equipment also supplies the accessories (cones, rods, hammers) required to perform the various DP tests.
