Abstract

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