Test Method Title

Standard Test Method for Determining the Integrity of Nonreinforced Geomembrane Seams Produced Using Thermo-Fusion Methods

Reference Number

ASTM D6392

Material

Geomembrane

Test Property

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 thermo-fusion methods. 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"
