Test Method Title
Standard Test Method for Field Measurement of Hydraulic Conductivity Limits of Porous Materials Using Two Stages of Infiltration from a Borehole
Reference Number
ASTM D6391
Material
Field Soil
Test Property
Hydraulic Conductivity, Flow Rate
Description of Test
The rate of flow of water into soil through the bottom of a sealed, cased borehole is measured in each of two stages, normally with a standpipe in the falling-head procedure. In stage 1, the bottom of the borehole is flush with the bottom of the casing. In stage 2, the borehole is extended below the bottom of the casing.
Number of Test Specimens
Typical Determined by site engineer
Test Specimen Size
5' x 5'
