|Publication Date:||1 June 2004|
|ICS Code (Measurement of fluid flow in general):||17.120.01|
|ICS Code (Geotextiles):||59.080.70|
1.1 This test method is an index test that covers laboratory measurement of flux through saturated geosynthetic clay liner (GCL) specimens using a flexible wall permeameter.
1.2 This test method is applicable to GCL products having geotextile backing(s). It may not be applicable to GCL products with geomembrane backing(s).
1.3 This test method provides a measurement of flux under a prescribed set of conditions that can be used for manufacturing quality control. The test method can also be used to check conformance. The flux value determined using this test method is not considered to be representative of the in-service flux of GCLs.
1.4 The values stated in SI units are to be regarded as the standard, unless other units are specifically given.
1.5 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.
