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.
