ASTM D4886-88(2002)

Standard Test Method for Abrasion Resistance of Geotextiles (Sand Paper/Sliding Block Method)

SCOPE
1.1 This test method covers the determination of resistance of geotextiles to abrasion using an abrasion tester. This test method at this point has only been evaluated for geotextiles-not geomembranes, grids, etc. Therefore, the test method is designated for geotextiles, not geosynthetics, as all products may not lend themselves to this test method for abrasion. If later developments indicate a wider scope for this test method, appropriate changes will be made.
1.2 The values stated in SI units are to be regarded as standard. The values given in inch-pound units are provided as information only.
1.3 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.
