Cone penetrometer method for:

- Liquid Limit determination. STANDARDS: CEN ISO/TS 17892-12 / BS 1377:2 / NF P94-052-1
- Shear Strength determination. STANDARD: CEN ISO/TS 17892-06

LIQUID LIMIT
The test is based on the relationship between the moisture content at which clay soils pass from a plastic to a liquid state. This value is obtained from the penetration capacity of the standard cone allowed to free fall into the sample for a period of 5 seconds.

SHEAR STRENGTH
The cone penetrometer is also suitable to measure the shear undrained strength of undisturbed and reconstituted soil samples as per CEN ISO/TS 17892-06 Standard.
