Test Method Title
Standard Test Methods for Determination of the Soil Water Characteristic Curve for Desorption Using Hanging Column, Pressure Extractor, Chilled Mirror Hygrometer, or Centrifuge **This method replaces both ASTM D2325 and D3152
Reference Number
ASTM D6836
Material
Soil
Test Property
Soil water characteristic curve
Description of Test
Methods A-C—Methods A-C yield soil water characteristic curves in terms of matric suction. Various suctions are applied to the soil and the corresponding water contents are measured. Two different procedures are used to apply the suction. In Method A, the matric suction is applied by reducing the pore water pressure while maintaining the pore gas pressure at the atmospheric condition. In Methods B and C, the pore water pressure is maintained at atmospheric pressure, and the pore gas pressure is raised to apply the suction via the axis translation principle.
