ASTM D7003 | Geomembranes | Tension Testing
ASTM D7003 is a test standard designed to measure the strip tensile strength and elongation of reinforced geomembranes. This test procedure is very similar to test standard ASTM D5035, except that it is written specifically for reinforced geomembranes as opposed to textile fabrics. A Universal Testing Machine which can pull at a Constant Rate of Extension (CRE) is required as well as the necessary grips to secure the sample.
Prior to conducting ASTM D7003, it is important to read the entire specification in the relevant ASTM publication.
ASTM D7003 | Geomembranes | Tension Testing
- Prepare at least five test specimens as described in the standard, paying attention to the alignment of the fiber reinforcement within the geomembrane.
- Specimens should be conditioned and tested at standard atmospheric conditions.
- Secure the test specimen in the grips, using a grip separation of 3 in.
- Apply the tensile force at a constant crosshead speed of 12 in/min. End the test at sample break.
Calculations:
- Peak Strength
- Elongation (%) at Peak Strength
