Therefore, the results should be applied to field situations with caution and by qualified personnel. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

However, this test method does not ensure complete saturation of the test specimen with water. 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.

However, astn test method is only intended to be used when water is the permeant liquid. Du abonnerer allerede dette emne. Username or password invalid. Atm not show this again. 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.

ASTM D Standard

Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. Experience has sometimes shown that flow atsm 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.
