Temperatures outside this range may be used, however, the user would have to determine the specific gravity of mercury and RT see There are six alternate methods or hydraulic systems, that may be used to measure the hydraulic conductivity. These hydraulic systems are as follows: 1. 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.

ASTM D 1. Scope 1. Temperatures outside this range may be used, however, the user would have to determine the specific gravity of mercury and RT see There are six alternate methods or hydraulic systems, that may be used to measure the hydraulic conductivity.

These hydraulic systems are as follows: 1. 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 key criterion is that the requirements covered in Section 5 have to be met. Strategies that may be possible when dealing with such impervious materials may include the following. Tightening the temperature control.

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. Properly shortening the length or enlarging the cross-sectional area, or both, of the test specimen. 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.

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

More D These test methods apply to water-saturated porous materials containing virtually no air. Permeation with other liquids, such as chemical wastes, can be accomplished using procedures similar to those described in these test methods. However, these test methods are only intended to be used when water is the permeant liquid.
