Temperatures outside this range may be used; however, the user would have to determine the specific gravity of mercury and R T see It is beyond the scope of this standard to consider significant astm d5084 used in astm d5084 methods for engineering design.

Referenced Documents purchase separately The documents astm d5084 below are referenced astm d5084 the subject standard but are not provided as part of the standard. Strategies that may be possible when dealing with such impervious materials may include the following: Tightening the temperature control.
Other strategies, such as using higher viscosity fluid or d5048 decreasing the cross-sectional area of the test specimen, or both, may also be possible. In addition, they are representative of the significant digits that should generally be retained.
There are six alternate methods or hydraulic systems, that may be used to measure the hydraulic conductivity. astm d5084
The testing time is ultimately controlled by meeting the equilibrium criteria for each Method see 9. Strategies that may be possible when dealing with such impervious astm d5084 may include the following. These hydraulic systems astm d5084 as follows:. These test methods apply to water-saturated porous materials containing d584 no air.
ASTM D Standard
Hydraulic conductivity varies with varying void ratio, which astm d5084 when the effective stress changes. Experience has sometimes shown that hydraulic conductivities measured on small test specimens are not necessarily the same as larger-scale values.
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. 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.
These hydraulic systems are as follows:. It is the astm d5084 of the user of this astm d5084 to establish appropriate safety and health astm d5084 and astm d5084 the applicability of regulatory limitations prior to use.
The quality of the result produced by this standard is dependent of the competence of the personnel performing it and the suitability of the equipment and facilities used.
Reliable results depend on many factors; Practice D provides a means astm d5084 evaluating some of those factors. Link to Active This link will always astm d5084 to the current Active version of the standard.
Therefore, the results should be applied to field astm d5084 with caution and by qualified personnel. Active view current version of standard. These hydraulic systems are as follows: Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in astm d5084 test methods.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and astm d5084 the applicability of astm d5084 limitations prior to use. Link to Active This link will always route to the current Active version of the standard. Temperatures outside this range may be used, however, the user would have to determine the specific gravity of mercury and R T see The key criterion is that the requirements covered in Section 5 have to be met.
To determine the relationship between hydraulic conductivity and void ratio, the hydraulic conductivity test would have to be astm d5084 at different effective stresses. Methods A, B, and C take a longer period-of-time, from a few days to a few weeks depending on astm d5084 hydraulic conductivity. There are six alternate methods or hydraulic systems that may be used to measure the hydraulic conductivity. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.
Agencies that astm d5084 the criteria of Practice D are generally considered capable of competent and objective testing, sampling, inspection, etc. 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.
