Penetrometers
Cone penetrometer method for:
- Liquid Limit determination BS 1377 :2 / NF P94-052-1 .
- Shear Strength determination CEN ISO/TS 17892-12
LIQUID LIMIT:
The test is used 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 5 seconds.
SHEAR STRENGTH:
The cone penetrometer is also suitable for measuring the shear undrained strength of undisturbed and reconstituted soil samples as per CEN ISO/TS
MODEL: SU161
