Standard Test Method for Hydraulic Conductivity Ratio (HCR) Testing of Soil/Geotextile Systems
|Publication Date:||15 May 1994|
|ICS Code (Geotextiles):||59.080.70|
This test method covers laboratory measurement of the hydraulic conductivity of water-saturated porous materials with a flexible-wall permeameter.
This test method may be used with undisturbed or compacted soil specimens that have a hydraulic conductivity less than or equal to 5 × 10−2 cm/s.
The filtration behavior of soils with hydraulic conductivities greater than 5 × 10−2 cm/s may be determined by the gradient ratio test (Test Method D5101).
The values stated in SI units are to be regarded as the standard, although other units are provided for information and clarification purposes.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
