Geotechnical investigation and testing — Field testing — Part 14: Borehole dynamic probing
This document specifies the equipment requirements, execution of and reporting on borehole dynamic probing.
NOTE This document fulfills the requirements for borehole dynamic probing as part of the geotechnical investigation and testing according to EN 1997-1 and EN 1997-2.
The document specifies technical requirements in respect to equipment and implementation, in order to extensively prevent incorrect appraisals of the subsoil conditions and to limit scatter in the probing results due to equipment and implementation.
