DIN EN ISO 22476-12:2009-10

This European Standard specifies equipment requirements, the execution of and reporting on mechanical cone penetration tests. The planning and evaluation of an investigation program and the application of its results to design is covered by EN1997-1 and EN1997-2. The results from a cone penetration test can in principle be used to evaluate: stratification; soil type; soil density and in situ stress conditions; mechanical soil properties: shear strength parameters; deformation and consolidation characteristics. This standard specifies the following features: the type of cone penetration test, according to Table 1; the Application Class, according to Table 2; the achievable penetration length or penetration depth; the elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a Datum; the location of the cone penetration test relative to a reproducible fixed location reference point; if applicable, the method of back filling of the hole in the soil resulting from the cone penetration test; if applicable, the depths and duration of the pore pressure dissipation tests.
