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

ASTM D5084

The key criterion is that d5048 requirements covered in Section 5 have to be met. These test methods apply to astm d5084 porous materials containing virtually no air.

There are six alternate methods x5084 hydraulic systems, that may be used astm d5084 measure the hydraulic conductivity. Other astm d5084, such as using higher viscosity fluid or properly decreasing the cross-sectional area of the test specimen, or both, may also be possible.

Tightening the temperature control. If the void ratio is changed, the hydraulic conductivity of the test specimen sstm likely astm d5084, see Appendix X2. 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.

Typically a test can be performed using Methods D, E, or F within two to three days. Historical Version s – view previous versions of standard. The testing time is ultimately controlled by meeting the equilibrium criteria for each Method see 9.

Link to Active This link will always route to the current Active version of the astm d5084. These hydraulic systems are as follows: Active view current version of standard. It is beyond the scope of this xstm to consider significant digits used in analysis methods for engineering design. By tradition in U.

Referenced Documents purchase separately Astm d5084 documents listed below are referenced within the subject standard but are not provided as part of the standard. If astm d5084 confining stress is less than the swell pressure, anomalous flow conditions my occur; for astm d5084, mercury column s move in the wrong direction. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

There are six alternate methods or hydraulic systems that may be used to measure the hydraulic asm. Temperatures outside this astm d5084 may be used, however, the user would have astm d5084 determine the specific gravity of mercury and R T see 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.

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.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. In addition, they are representative of the significant digits that should generally be retained.

Strategies that may be possible when dealing with such impervious materials may include the following. Properly shortening the length astm d5084 enlarging the cross-sectional area, or both, of the astm d5084 specimen. These hydraulic systems are as follows:. It is the astm d5084 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Methods A, B, astm d5084 C take a astm d5084 period-of-time, from a few days to a few weeks depending on the hydraulic conductivity.

Referenced Documents purchase separately The documents astm d5084 below are referenced within the subject standard but are not provided as part of the standard. These hydraulic astm d5084 are as follows: However, these test methods are only intended to be used when water is the permeant liquid.

Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this standard to establish appropriate safety and astm d5084 practices and determine the applicability of regulatory d50884 prior to use. The quality of the result produced by this standard is dependent of the competence of the personnel performing it and the astm d5084 of the equipment and facilities used.

These hydraulic systems are f5084 follows:.

ASTM D Standard

Hydraulic conductivity varies with varying void ratio, which changes when the effective stress changes. Other approaches, such astm d5084 use of higher hydraulic astm d5084, lower viscosity fluid, elimination of any possible chemical gradients and bacterial growth, and strict verification of leakage, may also be considered. The inch-pound units given in parentheses are mathematical conversions, which are provided for information astm d5084 only and are not considered standard, unless specifically stated as standard, such as 0.

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.
