Keywords

None Provided

Rationale

This revision includes additional sections to the body of the standard describing the thickness controlled measurement equipment and procedure for test sections including geonets, geocomposites and similar materials. It also includes a new Appendix addressing the application of Thickness Controlled Transmissivity with SIM to determine the long term Transmissivity of test sections by performing the test method with the flow conductive component compressed to the thickness determined with the SIM test at the elapsed time desired.
