This document establishes equipment, procedural and reporting requirements and recommendations on cone and piezocone penetration tests. NOTE - This document fulfils the requirements for cone and piezocone penetration tests as part of geotechnical investigation and testing according to the EN 1997 series. This document specifies the following features: a) type of cone penetration test; b) cone penetrometer class according to Table 2; c) test categories according to Table 3; d) penetration length or penetration depth; e) elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum; f) location of the cone penetration test relative to a reproducible fixed location reference point; g) pore pressure dissipation tests. This document covers onshore and nearshore cone penetration test (CPT). For requirements for offshore CPT, see ISO 19901-8
