These test methods apply to water-saturated porous materials containing virtually no air. 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.

The key criterion is that the requirements covered in Section 5 have to be met. It is the responsibility of the user of this standard to astm d5084 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The testing time is ultimately controlled by meeting the astm d5084 criteria for each Method see 9. Hydraulic conductivity varies with varying void ratio, astm d5084 changes when the effective stress changes.

Experience has sometimes shown that hydraulic conductivities measured on d0584 test specimens are not necessarily the same as larger-scale values.

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

The quality of the result produced by this standard is dependent astm d5084 the competence of the personnel performing it and the suitability of the equipment and facilities used. However, these test methods are only intended to be used when water is the permeant liquid.

There are six astm d5084 methods or hydraulic systems that may be used to measure the hydraulic conductivity. Link to Active This link will always route to the current Active version of the standard.

The procedures used do not consider material variation, astm d5084 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. Temperatures outside this range may be used; however, the user would have to astm d5084 the specific gravity of mercury and R T see Referenced Documents purchase separately The documents listed astm d5084 are referenced within the subject standard but are not provided as part of the standard.

These hydraulic systems are as follows: 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. 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.

In addition, they are representative of the significant digits that should generally be retained. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures astm d5084 to those described in these test methods.

Strategies that astm d5084 be possible when dealing with such impervious materials may include the following: It is astj the scope of this standard to consider significant digits used in analysis methods for engineering design.

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 as standard, such as 0. Active view astm d5084 version of standard.

These hydraulic systems are as follows:. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the astm d5084 objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. Link to Active This link will always route to the current Active version of the standard. If the void ratio is changed, the hydraulic conductivity of the test specimen will likely change, see Astm d5084 X2.

Typically a test can be performed using Astm d5084 D, E, or F within two to three days. Methods A, B, and C take a longer period-of-time, from a few days to a few weeks depending on the hydraulic conductivity. There are six alternate methods or hydraulic systems, that astm d5084 be used to measure the hydraulic conductivity.

These hydraulic systems are as follows:. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing, sampling, astm d5084, etc. The adoption of unsteady state measurements 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.

Therefore, the results should be applied s5084 field situations with caution and astm d5084 qualified personnel.

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

To astm d5084 the relationship between hydraulic conductivity and void ratio, the hydraulic conductivity test would have to be repeated at different effective stresses. These hydraulic systems are as follows: Reliable results depend on many factors; Practice D astm d5084 a means of evaluating some of those factors. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. In addition, they are representative of the significant digits that should generally be retained.
