Test Method Title
Standard Test Method for Determining the Integrity of Field Seams Used in Joining Geomembranes by Chemical Fusion Methods
seam peel and shear; seam strength
Description of Test
This test method describes destructive quality control and quality assurance tests used to determine the integrity of geomembrane seams produced by chemical-fusion methods. Samples are cured (either standard or accelerated) prior to testing. Specimens are tested in a tensile machine for peel strength (five specimens) and shear strength (five specimens). The peak strength and failure modes are reported.
Preferred Test Sample Size
1 linear foot of seam x 10" wide
Number of Test Specimens
10 (5 peel, 5 shear)
Test Specimen Size
1" x 8"
