New Test Method Determines Tensile Properties of Nonreinforced Geomembranes

A new test method from ASTM Subcommittee D35.10 on Geomembranes offers testers of geosynthetic materials increased reliability when monitoring product quality and consistency.

Approved July 10, ASTM D 6693, Standard Test Method for Determining Tensile Properties of Nonreinforced Polyethylene and Nonreinforced Flexible Polypropylene Geomembranes facilitates routine quality assurance (QA) and quality control (QC) testing. Application of the test method will increase uniformity from laboratory to laboratory when conducting tensile testing of nonreinforced geomembranes, according to Melody A. Adams, a project engineer for IT Corporation, Mahwah, N.J., and chairman of the task group that developed D 6693.

The task group was comprised of QA/QC lab technicians and managers, engineers, and manufacturers working under the guidelines of Committee D35 on Geosynthetics. The committee develops standards for geosynthetic products used in erosion control and other areas.

For further technical information, contact Melody A. Adams, IT Corporation, Mahwah, NJ (phone: 201/512-5762). Committee D35 meets Jan. 21-24 in Dallas, Texas. For meeting or membership details, contact Pat Picariello, manager, Technical Committee Operations, ASTM (phone: 610/832-9720). //
