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
