ISO 22476-1:2012 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.

Within the electrical cone and piezocone penetration test, two subcategories of the cone penetration test are considered:

  • electrical cone penetration test (CPT), which includes measurement of cone resistance and sleeve friction;
  • piezocone test (CPTU), which 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.

ISO 22476-1:2012 specifies the following features:

  1. type of cone penetration test;
  2. application class;
  3. penetration length or penetration depth;
  4. elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum;
  5. location of the cone penetration test relative to a reproducible fixed location reference point;
  6. pore pressure dissipation tests.
