Annotation of standard text ASTM D6495/D6495M-18(2022) :

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.
