Standard ASTM D5567-94R06

Standard Test Method for Hydraulic Conductivity Ratio (HCR) Testing of Soil/Geotextile Systems
Publication date
59.080.70 Geotextiles
Summary :

1.1 This test method covers laboratory measurement of the hydraulic conductivity of water-saturated porous materials with a flexible-wall permeameter.

1.2 This test method may be used with undisturbed or compacted soil specimens that have a hydraulic conductivity less than or equal to 5 x 102 cm/s.

1.3 The filtration behavior of soils with hydraulic conductivities greater than 5 x 102 cm/s may be determined by the gradient ratio test (Test Method D 5101).

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
