Standard Test Method for Tensile Strength of Geosynthetic Clay Liners

Importancia y uso:

5.1 This test method may be used for the acceptance testing of commercial shipments of GCLs, but caution is advised since information about between-laboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable.

5.1.1 In cases of a dispute arising from differences in reported test results when using this test method for acceptance of shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias. The two parties should take a group of test samples that are as homogeneous as possible and which are from the lot of material in question.

5.2 Some modification of clamping techniques may be necessary for a given GCL, depending upon its structure. Specimen clamping may be modified as required at the discretion of the individual laboratory, provided a representative tensile strength is obtained. In any event, the procedure described in Section 10 of this test method for obtaining tensile strength must be maintained.

5.3 This test method is applicable for testing GCLs as received. It is used with a constant rate of extension type tension apparatus.
