1.1 This test method is used to measure 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 The values stated in SI units are to be regarded as the standard. The values are provided in inch-pound units for information only.

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

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.
