Geotechnical investigation and testing. Field testing. Electrical cone and piezocone penetration test | Status: Current

1 Scope 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:

1. a) type of cone penetration test;
2. b) cone penetrometer class according to Table 2;
3. c) test categories according to Table 3;
4. d) penetration length or penetration depth;
5. e) elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum;
6. f) location of the cone penetration test relative to a reproducible fixed location reference point;
7. g) pore pressure dissipation tests.

This document covers onshore and nearshore cone penetration test (CPT). For requirements for offshore CPT, see ISO 19901‑8.
