Typically a test can be performed using Methods D, E, or F within two to three days.

Other items, such as use of higher hydraulic gradients, lower viscosity fluid, elimination of astm d5084 possible chemical gradients and bacterial growth, and strict verification of leakage, may also be considered. Temperatures outside this range may be used; however, the user would have to determine the specific gravity of mercury and R T see These hydraulic systems are as follows: The adoption of unsteady state measurements by using high-accuracy equipment along with the rigorous analyses for determining the hydraulic astm d5084 this approach reduces testing duration according to Zhang et al.

ASTM D5084

Hydraulic conductivity varies with varying void ratio, which changes when the effective stress changes. Users of this standard are cautioned that compliance with Practice D does not in itself astm d5084 reliable x5084. Therefore, the results should be applied to field situations with astm d5084 and by qualified personnel. Tightening the temperature control. Link to Active This link will always route to the current Active version of the standard.

Strategies that may be possible when dealing with such impervious materials may include the following. Permeation with other liquids, such as chemical wastes, can be astm d5084 using procedures similar to those described astm d5084 these test methods.

Methods A, B, and C take a longer period-of-time, from a few days to a few weeks depending astm d5084 the hydraulic conductivity. However, these test methods are only intended to be used when water is the permeant liquid. There are six alternate methods or hydraulic systems, that may be used astm d5084 measure the hydraulic conductivity. The key criterion is that the requirements covered in Section 5 have astm d5084 be met.

If the void ratio is changed, the hydraulic conductivity of the test specimen will likely change, see Appendix X2. Referenced Documents astm d5084 separately The documents listed below are referenced within the subject standard but astm d5084 asrm provided as part of the standard.

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

The d0584 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 common practice to increase or reduce astm d5084 digits of reported data to be commensurate with these considerations.

There are six alternate methods or hydraulic systems that may be used to measure the hydraulic conductivity. Historical Version s – view previous versions of standard. The testing time is ultimately controlled by d50844 the equilibrium criteria for astk Method see 9. The quality of the result produced by this standard is d084 of the competence of the personnel performing it and the suitability of the equipment and facilities used.

Other approaches, such as use of higher hydraulic astm d5084, lower viscosity fluid, elimination of any possible chemical gradients and bacterial growth, and astm d5084 verification of leakage, may also be considered.

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

The inch-pound units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard, unless specifically stated astm d5084 standard, such as 0. Agencies that meet the criteria of Practice D are generally considered capable astm d5084 competent and objective testing, sampling, inspection, etc. Link to Active This link will always route to the current Active version of the standard.

These hydraulic e5084 are asstm follows:. By tradition in U. 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.

In addition, they are representative of the significant digits that should generally be retained. It is the responsibility of the user of this standard to establish appropriate safety and health practices and astm d5084 the applicability of regulatory limitations prior to use. To determine the relationship between hydraulic conductivity and void ratio, the hydraulic conductivity test would have to be repeated at different effective stresses.

Temperatures outside this range astm d5084 be used, however, the user would atsm to determine the specific gravity of mercury and R T see Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

These hydraulic systems are as follows: These test methods apply to water-saturated porous materials containing virtually no air.

It is beyond the scope of this standard to consider significant digits used in analysis methods astm d5084 engineering design. Experience has sometimes shown that hydraulic conductivities measured on small test specimens are not necessarily the same as larger-scale values. 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.

It is the responsibility of the user of this standard to establish appropriate safety and astm d5084 practices and determine the applicability astm d5084 regulatory limitations prior to use. Strategies that may be possible when dealing with such impervious materials may include the following: In addition, they are astn of the c5084 digits that should generally be retained.

These hydraulic systems are as follows:. Properly shortening the length astm d5084 enlarging the cross-sectional area, or both, of the test specimen. The key criterion is that the requirements covered in Section 5 have to be met.
