This document deals with equipment requirements, the execution of and reporting on electrical cone and piezocone penetration tests as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2. The results from a cone penetration test are used to evaluate: - stratification; - soil type; - soil density and in situ stress conditions; - mechanical soil properties: - shear strength parameters; - deformation and consolidation characteristics. Within the electrical cone and piezocone penetration test, two subcategories of the cone penetration test are considered: - The electrical cone penetration test (CPT) that includes measurement of cone resistance and sleeve friction; - The piezocone test (CPTU) that is a cone penetration test with the additional measurement of pore pressure. The CPTU is performed like a CPT with the measurement of the pore pressure at one or several locations on the penetrometer surface. NOTE CPT or CPTU are also used without measurement of sleeve friction. This document specifies the following features: a) the type of cone penetration test, according to Table 1; b) the Application Class, according to Table 2; c) the acdievable penetration length or penetration depth; d) the elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum; e) the location of the cone penetration test relative to a reproducible fixed location reference point; f) if applicable, the method of back filling of the hole in the soil resulting from the cone penetration test; g) if applicable, the depths and duration of the pore pressure dissipation tests.
