ASTM-D6524/D6524M 2016(Redline)

1.1 This test method covers the resiliency or recovery of turf reinforcement mats (TRMs) after they have been subjected to three cycles of loading at 689 kPa [100 psi] for 1 min/per cycle.

1.2 This test method does not provide resiliency values for TRMs under variable normal compressive stresses. This test method determines nominal resiliency.

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.
