OS GSO ISO 22476-12:2017 Scope
This part of ISO 22476 specifies a mechanical cone penetration test (CPTM), including equipment
requirements, execution and reporting. The results from such geotechnical testing are especially suited to the
qualitative and/or quantitative determination of a soil profile — together with direct investigations — or as a
relative comparison with other in situ tests.
The results from a cone penetration test can in principle be used to evaluate stratification, soil type, and
geotechnical parameters such as soil density, shear-strength parameters and deformation and consolidation
characteristics.
This part of ISO 22476 specifies the following features:
⎯ type of cone penetration test (see Table 1);
⎯ application class (see Table 2);
⎯ penetration length or penetration depth;
⎯ elevation of the ground surface or 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.
NOTE The planning and evaluation of an investigation programme and the application of its results to design are
covered by EN 1997-1 and EN 1997-2.
