Standard Test Method for Determination of Ply Adhesion Strength of Reinforced Geomembranes

Importancia y uso:

5.1 This method is an index test and measures the force required to separate individual plies of a reinforced geomembrane. The acceptable value of adhesion will vary for different types of products. However, for a particular type of product, minimum values of ply adhesion can be determined and agreed to by producer and consumer, and both can monitor to ensure compliance with the agreed-upon value.

5.2 Disputes—In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical difference between their laboratories. Competent statistical assistance is recommended for the investigation of this difference. At a minimum, the two parties should take a group of test specimens which are from the same lot of material as those type in question and which are as homogeneous as possible. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing began. If a difference is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results in the light of the known difference.
