In cases where it is essential to saturate the test specimen fully with water, the compacted specimen may be tested using Test Method D The problem tends to be of minimal significance for materials that swell when exposed to water for example, compacted, clayey soils but can be a very serious problem for materials that might tend to shrink and pull away from the walls asstm the permeameter.

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.

Test Method D is recommended for any material that tends to shrink when exposed to the permeant liquid. Permeation with other liquids, such as chemical wastes, can be accomplished using astk similar to those described in this test method.

Experience has sometimes shown that flow patterns in small, laboratory-prepared test specimens do not necessarily follow the same patterns on large astmm scales and that hydraulic conductivities measured on small test specimens are not necessarily the same as larger-scale values.
