This guide covers guidelines for the acceptance testing requirements for geosynthetic clay liner (GCL) materials, describing types of tests, test methods, and recommended verifications and is intended to aid purchasers, installers, contractors, owners, operators, designers and agencies in establishing a minimum level of effort for product acceptance testing and verification. This guide suggests the types of tests, the methods of the testing, and verification requirements for acceptance testing of GCL materials. It should be recognized that parties, organizations or representatives may perform additional tests and/or at other frequencies than required in this standard guide. In this case, the project-specific acceptance plan will then take precedence over this standard guide. Different properties such as clay mass per unit area, swell index, fluid loss, grab tensile strength, tensile strength, density and thickness of geomembrane support, and bonding peel strength shall be determined by subjecting the material to different test methods.
1.1 Thisguide covers guidelines for the acceptance testing requirements forgeosynthetic clay liner (GCL) materials, describing types of tests,test methods, and recommended verifications.
1.2 Thisguide is intended to aid purchasers, installers, contractors,owners, operators, designers, and agencies in establishing aminimum level of effort for product acceptance testing andverification. This is intended to ensure that the supplied GCLrolls meet accepted material specifications.
1.3 Thevalues stated in either SI units or inch-pound units are to beregarded separately as standard. The values stated in each systemmay not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systemsmay result in non-conformance with the standard.
1.4This guide offers an organized collection ofinformation or a series of options and does not recommend aspecific course of action. This guide cannot replace education orexperience and should be used in conjunction with professionaljudgment. Not all aspects of this guide may be applicable in allcircumstances. This guide is not intended to represent or replacethe standard of care by which the adequacy of a given professionalservice must be judged, nor should this guide be applied withoutconsideration of a project's many unique aspects. The word“Standard” in the title of this guide means only that the guide hasbeen approved through the ASTM consensus process.
1.5This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety,health, and environmental practices and determine the applicabilityof regulatory limitations prior to use.
1.6This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
