(Practice)Standard Practice for In Field Immersion Testing of Geosynthetics
Standard Practice for In Field Immersion Testing of Geosynthetics
SIGNIFICANCE AND USE
This practice provides an approach and methodology for conducting field immersion testing of geosynthetics used in the construction of liners in reservoirs, ponds, impoundments, or landfills for containing liquids and solids. This practice should be performed in accordance to and in conjunction with D 5322 for assessing chemical resistance under both laboratory and field conditions.
The specification of procedures in this practice is intended to serve as a guide for those wishing to compare or investigate the chemical resistance of geosynthetics under actual field conditions.
SCOPE
1.1 This practice describes an approach and methodology for immersion testing of geosynthetics (for example, geomembranes used for landfill liner).
1.2 This practice does not provide for definition of the testing to be performed on the geosynthetic samples for field immersion. This practice does not address the determination of resistance of the geosynthetic to the liquid in which it is immersed. The user of this practice is referred to the appropriate Standard Guide for Tests to evaluate the chemical resistance and for defining the testing to be performed for each of the geosynthetic components listed in 2.1.
1.3 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.
