Geotechnical Investigation and Testing - Field Testing - Part 1: Electrical Cone and Piezocone Penetration Test
Also Known As:
ISO 22476-1 is a standard that focuses on geotechnical investigation and testing in the field, specifically the electrical cone and piezocone penetration tests. The standard outlines the requirements for equipment, execution, and reporting of these tests.
The electrical cone penetration test (CPT) measures cone resistance and sleeve friction, while the electrical piezocone test (CPTU) includes the measurement of pore pressure in addition to cone resistance and sleeve friction. The CPTU is performed similarly to the CPT, but with the added measurement of pore pressure at one or more locations on the penetrometer surface.
This part of the standard specifies various features such as the type of cone penetration test, the class of the cone penetrometer, the test categories, the penetration length or depth, the elevation of the ground surface or underwater ground surface, the location of the test relative to a reference point, and the pore pressure dissipation tests.
