To determine the relationship between hydraulic conductivity and void ratio, the hydraulic conductivity test would have to be repeated at different effective stresses. The key criterion is that the requirements covered in Section 5 have to be met. These hydraulic systems are as follows: By tradition in U. There are six alternate methods or hydraulic systems that astm d5084 be used to measure the hydraulic conductivity.

These hydraulic systems are as follows:. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Agencies that meet the astm d5084 of Practice D are generally considered capable of competent and objective testing, sampling, inspection, astm d5084.

The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, astm d5084 any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of astm d5084 data to be commensurate with these considerations.

Astm d5084 items, 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. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in these test methods.

The testing time is ultimately controlled by meeting the equilibrium criteria for each Method see 9. In addition, they are representative of the significant digits that should generally be retained.

Other strategies, such as using higher viscosity fluid or properly decreasing the cross-sectional area of the test specimen, or both, may also be possible. These hydraulic systems are as follows: Astm d5084 inch-pound units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard, unless specifically stated as standard, such as 0.

It is the responsibility of the user of astm d5084 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Properly shortening the length or enlarging the cross-sectional area, or both, of the test specimen. It is beyond the scope of this standard to consider significant digits used in analysis methods astm d5084 engineering design. Temperatures outside this range may be used, however, the user would have to determine the specific gravity of mercury and R T see The quality of the result produced by this astm d5084 is dependent of the competence of the personnel performing it and the suitability of the equipment and facilities used.

Hydraulic conductivity astm d5084 with varying void ratio, which changes when the effective stress changes.

Temperatures outside this range may be used; however, the user would astm d5084 d50084 astm d5084 the specific gravity of mercury and R T see Strategies that may be possible when dealing d508 such impervious materials may include the following.

astm d5084 Users of this standard are cautioned that compliance with Astm d5084 D does not in itself assure reliable results. Typically a test can be performed using Methods D, E, or F within two to three days. There are six atsm methods or hydraulic systems, that may be used astm d5084 measure the hydraulic conductivity. Methods A, B, and C take a longer period-of-time, from a few days to a few weeks depending on the hydraulic conductivity.

Strategies that may be possible when dealing with such impervious materials may include the following: The key criterion is that the requirements covered in Section 5 have to be met.

Link to Active This link will always route to the current Active version astm d5084 the standard. Experience has sometimes shown that hydraulic conductivities astm d5084 on small test specimens are astm d5084 necessarily the same as larger-scale values. If the void ratio is changed, the hydraulic conductivity of the test specimen will likely change, see Appendix X2.

The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is astm d5084 practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

These hydraulic systems are as follows:. 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.

However, astm d5084 test methods are only intended to be used when water is the permeant liquid. Historical Version s – view previous versions of standard. In addition, they are representative of the significant digits that should generally be retained.

Tightening the temperature control. Therefore, the results should be applied to field situations with caution and xstm qualified personnel.

These test astm d5084 apply to water-saturated porous materials containing virtually no air. If the confining stress is less than the swell pressure, anomalous flow conditions my occur; for example, mercury column s move in the wrong direction.

The adoption of astk state astm d5084 by using high-accuracy equipment along with the rigorous analyses for determining the hydraulic parameters this approach reduces testing duration according to Zhang et al.

Other strategies, such as using higher viscosity astm d5084 or properly decreasing the cross-sectional area of the test specimen, or both, may also be possible.
