Cell Seam Peal Strength Test

Short term Seam Peel-Strength Test

Cell seam strength shall be uniform over the full depth of the cell. Short-term peel strength shall be tested per U.S. Army Corps of Engineers Technical Report GL-86-19 Appendix A. Minimum seam peal strengths shall be 2000N for 200mm cell depth and the strength is directly proportionate to the cell depth.

Long term Seam Hang-Strength Test

Seam hang-strength test shall be performed for a minimum period of 7 days in a temperature-controlled environment that undergoes change on a 1 hr. cycle from room temperature to 54deg C. (130F). Room temperature is defined in ASTM E41. Test samples shall be made by welding of two 100mm wide polyethylene strips together. A test sample consisting of two carbon black stabilized strips shall support a 72.5 kg. (160lb) load for the test period.

Alternative Long term Seam Hang-Strength Test

Seam hang-strength test shall be performed for a period of 30 days at room temperature. Room temperature is defined in ASTM E41. Test samples shall be made by welding of two 100mm wide polyethylene strips together. A test sample consisting of two carbon black stabilized strips shall support a 72.5 kg. (160lb) load for the test period.
