WZ-10 Geotextile Membrane Multi axial Elongation Testing Machine

1 Standard D5994/D5994M Multi axial Elongation Testing Machine for GeomembraneOverview

According to the testing methodD5199Testing methodsD5994/D5994MOr measure the thickness of the test sample according to the corresponding standard of the tested material.

1.1 This testing method covers the effects of geomembranes onMeasurement of out of plane response of force applied perpendicular to the initial plane of the sample.

1.2 Fix the geomembrane specimen at the edge of a large-diameter pressure vessel, apply pressure to the specimen to cause out of plane deformation and failure, analyze the fracture deformation with pressure information, and evaluate various materials.

Measure the thickness of the test sample according to testing methods D5199, D5994/D5994M, or the corresponding standards of the tested material.

Use air to pressurize the container.

Place the sample at the opening of the container. Ensure that the sample does not sag. For certain types of geomembranes, rubber seals may be required on the bottom of the sample to prevent air leakage when increasing pressure.

4. Place the clamping ring. Ensure that the sample remains flat when clamping the edge of the sample.

At room temperature, open the intake valve and allow compressed air to enter the container. Adjust the valve opening to control the speed of displacement.

Record the midpoint deflection and pressure at least once per second.

Continue the experiment at the specified rate of midpoint deflection until the specimen ruptures or reaches a predetermined endpoint.

Repeat the above steps with two additional samples.
