1.1 This test method is limited to measuring the nominal thickness of geotextiles, smooth surfaced geomembranes, geonets, and geocomposite drainage products.
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 thickness values for geosynthetics under variable normal compressive stresses. This test method determines nominal thickness, not necessarily minimum thickness.
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.
