1.1 This test method is used to measure the nominal thickness of permanent rolled erosion control products.

1.2 The values stated in SI units are to be considered as the standard. The values are provided in inch-pound units for information only.

1.3 This test method does not provide thickness values for permanent rolled erosion control products under variable compressive stresses. This test method determines nominal thickness, not necessarily minimum thickness.

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.
