1. Scope

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 10 ² cm/s.

1.3 The filtration behavior of soils with hydraulic conductivities greater than 5 x 10 ² 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
