5.1 The compression behavior test for TRMs is intended to be an index test. It is anticipated that the results of the compression behavior test will be used to evaluate product. The results of the analyses also may be used to compare the relative compressive yield points of materials that exhibit a detectable compressive yield point. It is anticipated that this test will be used for quality control testing to evaluate uniformity and consistency within a lot or between lots where sample geometry factors, for example, thickness, or materials may have changed. Note 1: This is a one-dimensional test for compressive loading
of a TRM in one plane.
5.1.1 The compressive yield point of TRMs may be evaluated from the stress/strain relationship. Many materials exhibit compressive deformation but may not show a distinct compressive yield point. 5.2 This test method can be used to evaluate the short-term stress/strain behavior of TRMs under compressive stress while loaded at a constant rate of deformation. 5.3 This test method may be used for acceptance testing of commercial shipments of TRMs but caution is advised because interlaboratory testing is incomplete. 5.3.1 In the 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 statistically bias between their laboratories. Competent statistical assistance is recommended for the investigations of bias. As a minimum, two parties should take a group of test specimens from material shipped to project. The test specimens then should be assigned randomly in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results in the light of the known bias. |

|
1.1 The test method establishes the procedures for evaluation of the deformations of a turf reinforcement mat (TRM) under short-term compressive loading. This test method is strictly an index test method to be used to verify the compressive strength consistency of a given manufactured geosynthetic. Results from this test method should not be considered as an indication of actual or long-term performance of the TRM in field applications. 1.2 Since these TRMs experience multidirectional compressive loadings in the field, this test method will not show actual field performance and should not be used for this specific objective. The evaluation of the results also should recognize that the determination of the short term single plane compressive behavior of geosynthetics does not reflect the installed performance of TRMs and, therefore, should not be used as the only method of product or performance specification. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
