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.

ASTM D5856

However, this test method is only intended to be used when water is the permeant liquid. In cases where it is essential to saturate the test specimen fully with water, the compacted specimen may be tested using Test Method D Test Method D is recommended for any material that tends to shrink when exposed to the permeant liquid.

Are you sure you want to unsubscribe monitoring? Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results.

Historical Version s – view previous versions of standard. However, this test method does not ensure complete saturation of the test specimen with water. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applic. This test method applies to porous materials containing little or no air. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in this test method.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 of the permeameter.

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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Therefore, the results should be applied to field situations with caution and by qualified personnel.
