However, when the hydraulic gradient acting on a test specimen is changed, the state of stress will also change, and, if the specimen or pore fluid is compressible, the volume of the test specimen or pore fluid will change. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in this test method.

In cases where it is asgm to saturate the test specimen fully with water, the compacted specimen may asttm tested using Test Method D However, this test method does not ensure complete saturation of the test specimen with water.

Do not show this again. However, this test method is only intended to be used when water is the permeant liquid. The problem tends to be of minimal significance for materials that swell when exposed to water for example, compacted, clayey soils ashm can be a very serious problem for materials that might tend to shrink and pull away from the walls of the permeameter. Test Method D is recommended for any material that tends to shrink when exposed to the permeant liquid.

ASTM D Standard

This test method applies to porous materials containing little or no air. Experience has sometimes shown that flow patterns in small, laboratory-prepared test specimens do not necessarily follow the same patterns on large field scales and that hydraulic conductivities measured on small test specimens are not necessarily the same as larger-scale values.
