Soil Cone Penetrometer
|Publication Date:||1 February 1999|
Purpose and Scope
The soil cone penetrometer (Figure 1) is recommended as a measuring device to provide a standard uniform method of characterizing the penetration resistance of soils. The force required to press the 30° circular cone through the soil, expressed in kilopascals, is an index of soil strength called the cone index.
The Standard is intended for the following purposes:
To provide a common method of constructing a device capable of measuring general soil mechanical conditions that facilitates the reporting and interpretation of soil data by different research workers.
To assist those who work with different soils and soil conditions and who need a measure of soil mechanical properties for comparative purposes.
