1.1 This method is used to measure the adhesion strength (180 degree peel) between plies of reinforced geomembranes such as internally-reinforced geomembranes and coated fabrics.

1.2 This method is not intended for determining the strength of geomembrane seams or for determining the ply adhesion strength of geocomposite components (such as nonwoven geotextile bonded to geomembrane, or geotextile bonded to drainage core).

1.3 The values in SI units are the standard. The values provided in inch-pound units are for information only.

1.4 This standard may involve hazardous materials, operations and equipment. 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.
