Test Method Title

Standard Test Methods for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter

Reference Number

ASTM D5084

Material

Soil

Test Property

Permeability, Flow Rate, Hydraulic conductivity

Description of Test

This test method covers laboratory measurement of the hydraulic conductivity (also referred to as coefficient of permeability) of water-saturated porous materials with a flexible wall permeameter. This test method may be utilized with undisturbed or compacted specimens having a hydraulic conductivity less than or equal to 1x10-5m/s (1x10-3cm/s). The hydraulic conductivity of materials with hydraulic conductivities greater the 1x10-5m/s may be determined by Test Method D2434. This test method applies to one-dimensional, laminar flow of water within porous materials such as soil and rock.

Preferred Test Sample Size

Number of Test Specimens

1

Test Specimen Size

Minimum diameter of 1.0 in x 1in height, with the largest particle size 1/6 the diameter of the specimen.

Keywords
