Test Method Title

Standard Test Method for Determining Performance Strength of Geomembranes by the Wide Strip Tensile Method

Reference Number

ASTM D4885

Material

Geomembrane

Test Property

wide-width tensile strength

Description of Test

A relatively wide specimen is gripped across its entire width in the clamps of a constant rate of extension type tensile testing machine operated at a prescribed rate of extension, applying a uniaxial load to the specimen until the specimen ruptures. Tensile strength, elongation, initial and secant modulus and breaking toughness of the test specimen can be calculated from machine scales, dials, recording charts or an interfaced computer.

Preferred Test Sample Size

3' x roll width

Number of Test Specimens

6 machine direction 6 cross machine direction

Test Specimen Size

8" x 8"

Keywords

wide-width, tensile, performance strength
