Test Method Title
Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer
Reference Number
ASTM D3385
Material
Field Soil
Test Property
Permeability, Flow Rate
Description of Test
The double-ring infiltrometer method consists of driving two open cylinders, one inside the other, into the ground, partially filling the rings with water or other liquid, and then maintaining the liquid at a constant level. The volume of liquid added to the inner ring, to maintain the liquid level constant is the measure of the volume of liquid that infiltrates the soil. The volume infiltrated during timed intervals is converted to an incremental infiltration velocity, usually expressed in centimeters per hour or inch per hour.
