Test Method Title
Standard Test Method for Field Measurement of Hydraulic Conductivity Limits of Porous Materials Using Two Stages of Infiltration from a Borehole
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.
