Work Item
ASTM WK95349
Revision of D6766-20a Standard Test Method for Evaluation of Hydraulic Properties of Geosynthetic Clay Liners Permeated with Potentially Incompatible Aqueous Solutions
Rationale
This standard remains in active use and does not require immediate technical revision. A reapproval ballot without change will be issued to reaffirm its continued relevance. In parallel, a subcommittee-level effort will develop proposed language to move the guidance from Note 11 into Section 8.2. This will clarify the acceptability of alternative stress conditions when justified, enhancing clarity and usability without altering current practice.
