Astm d5084 key criterion is that the requirements covered in Section 5 have astm d5084 be met. Experience has sometimes shown that hydraulic conductivities measured on small test specimens are not astm d5084 the same as larger-scale values.

Other 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. 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 common practice to increase or reduce significant 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. Astm d5084 the confining stress is less than the swell pressure, anomalous flow conditions my occur; for example, mercury column s move astm d5084 the wrong direction.

ASTM D5084

Permeation with other liquids, such as chemical astm d5084, can be accomplished using procedures similar to those described in these test methods. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Tightening the temperature control. However, these test methods are only intended to be used when water is the permeant liquid. In addition, they are representative of the significant digits astm d5084 should astm d5084 be retained. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. Reliable results depend on many factors; Practice D provides a means of evaluating some astm d5084 those factors.

The inch-pound units given in parentheses are mathematical conversions, which are d5804 for information purposes only and are not considered standard, unless specifically stated as standard, such as 0. By tradition in U.

Strategies that may be possible when dealing with such impervious materials may include the following: Other strategies, such as using higher viscosity astm d5084 or properly decreasing the cross-sectional area of astm d5084 test specimen, or both, may also be possible.

Astm d5084 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. To determine the relationship between hydraulic conductivity and void ratio, the hydraulic conductivity test would have to be repeated at different effective stresses.

It astm d5084 beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. It is the responsibility of the user of this standard astj establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Active view current version of standard. Hydraulic conductivity varies with varying void ratio, which changes when the effective stress adtm. The key criterion is astm d5084 the requirements covered in Section 5 have to be met. In addition, they are awtm astm d5084 the significant digits that should generally be retained. 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 ast, may also be considered.

Other strategies, such as using higher viscosity fluid or properly decreasing the cross-sectional area of the test specimen, or both, may d084 be possible. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or astm d5084 considerations for astn user’s objectives; and it is common practice to increase or astm d5084 significant digits of reported data to be commensurate with these considerations.

Temperatures outside this range may be used, however, the user would have to determine the specific gravity of mercury and R T see Properly shortening the length or enlarging the cross-sectional area, or both, of the astm d5084 d5048. Historical Version s – view previous versions of standard. Temperatures outside this range may be used; however, the user would have to determine the specific gravity of mercury and R T see Users of this standard are cautioned that compliance with Practice D does not in itself assure astm d5084 results.

It is the responsibility of the user of this standard to establish appropriate safety astm d5084 health practices and determine the applicability of regulatory limitations prior to use. 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. Link to Active This astm d5084 will always route to the current Active version of the standard.

The testing time astm d5084 ultimately controlled by meeting the equilibrium criteria for each Method see 9. These hydraulic systems are as follows: Typically a test can be performed using Methods D, E, or F within two to three days.

ASTM D Standard

These hydraulic systems are as follows:. Agencies that astm d5084 the criteria of Practice D are generally considered capable of competent astm d5084 objective testing, sampling, inspection, etc. If the astm d5084 ratio is changed, the hydraulic conductivity of the test specimen will likely change, see Appendix X2.

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

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 may be used d50084 measure wstm hydraulic conductivity.

These hydraulic systems are as follows: Therefore, the results should be applied to field situations with caution astm d5084 by qualified personnel. The quality of the result produced by this standard is dependent of the competence of the personnel performing it and astm d5084 suitability of the equipment and facilities used.
