ASTM-D5993 › Standard Test Method for Measuring Mass per Unit Area of Geosynthetic Clay Liners
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the laboratory determination of the mass unit per area of a sample of a geosynthetic clay liner (GCL). The dry mass of the clay can be found by simply subtracting the manufacturer's reported nominal mass of the geosynthetic component(s) from the total mass of the dry GCL. The moisture content of the GCL can also be determined by subtracting the initial total mass of the GCL from the total mass of the dry GCL.
1.2 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. See Section 7 for specific precautionary statements.
