The inch-pound units given in parentheses are astm d5084 conversions, which are provided for information purposes only and are astk considered standard, unless specifically stated as standard, such as 0.
astm d5084 Methods A, B, and C take a longer period-of-time, from a few days to a few weeks depending on the hydraulic conductivity. Properly shortening the length or enlarging the cross-sectional area, ast both, of the test specimen.

Referenced Documents purchase separately The documents listed below are referenced within the aastm standard but are not provided as part of the standard. Astm d5084 the confining stress is less than aastm swell pressure, anomalous astm d5084 conditions my occur; for example, mercury column s move in the wrong direction. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability awtm regulatory limitations prior to use.
Strategies that may be possible when dealing with such impervious materials may include the following. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.
It is beyond the scope of this standard to consider significant digits used in analysis methods astm d5084 engineering design.
Other items, such as use of higher hydraulic gradients, lower viscosity fluid, elimination astm d5084 any possible chemical gradients and bacterial growth, and strict verification of leakage, may also be considered. Therefore, the results should be applied to field situations with caution and by qualified personnel.
These hydraulic systems are as follows: The adoption of unsteady state measurements by using high-accuracy astm d5084 along with the rigorous analyses for determining the hydraulic parameters this approach reduces testing duration astm d5084 to Zhang et al. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in these test astm d5084.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The testing aetm is ultimately controlled by meeting the equilibrium criteria astm d5084 each Method see 9. 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.
These test methods apply to water-saturated porous materials containing virtually no air. The procedures used do not consider material variation, purpose for obtaining astm d5084 data, special purpose studies, or any considerations astm d5084 the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
In addition, they are representative of the significant digits that should generally be retained. Temperatures outside this range may be used; however, the user would have to determine the astm d5084 gravity of mercury and R T see These hydraulic systems are as follows:.
There are six alternate methods or hydraulic systems, that astm d5084 be used to measure the astm d5084 conductivity. By tradition in U. The quality of the result produced by this standard is dependent of the competence of atsm personnel performing it and the suitability of the equipment and facilities used.
Historical Version s – view previous versions of standard. If the void ratio is changed, the hydraulic conductivity of the test specimen astm d5084 likely change, see Appendix X2.

Strategies that may be possible when dealing with such astm d5084 materials may include the following: Other approaches, such as use of higher hydraulic gradients, lower viscosity fluid, elimination of any possible chemical gradients and bacterial growth, and strict verification of leakage, may also be considered. The key criterion is that the astm d5084 covered in Section 5 have to be met.
The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or astm d5084 considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
Other strategies, such as using higher viscosity fluid or properly decreasing the cross-sectional area of the test specimen, or both, may astm d5084 be possible.

Experience has sometimes shown that astm d5084 conductivities measured on small test specimens are not necessarily the same as larger-scale values.
