|Significance and Use|
5.1 The ability to maintain design function (for example, barrier) or design properties (for example, peel strength, chemical resistance, etc.), or both, of a geosynthetic clay liner may be affected by damage to the physical structure of the GCL due to the rigors of field installation. The effect of damage may be assessed by analyzing specimens cut from sample(s) retrieved after installation in a representative test pad. Analysis may be performed with visual examination or laboratory testing of specimens from the control sample(s), and from the exhumed sample(s).
5.2 A uniform practice for installing and retrieving representative sample(s) from a test pad is needed to assess installation damage using project-specific or generally accepted, representative materials and procedures. Damage of a specific grade and type of GCL under specific installation procedures may be assessed with sample(s) exhumed from a full-scale test pad.
1.1 This practice covers standardized procedures for obtaining samples of geosynthetic clay liners (GCLs) from a test pad for use in assessment of the effects immediately after installation caused only by the installation techniques. The assessment may include physical testing. This practice is applicable to GCLs only.
1.2 This practice is limited to full-scale test pads, and does not address laboratory modeling of field conditions. This practice does not address which test method(s) to use for quantifying installation damage.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
