Standard Test Method for Measuring Asperity Height of Textured Geomembranes
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers a procedure to measure the asperity height of textured geomembranes.
1.2 This test method does not provide for measurement of the spacing between the asperities nor of the complete profile of the textured surface.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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.
Significance and Use
5.1 The asperity height is an index property used to quantify one of the physical attributes related to the surface roughness of textured geomembranes.
5.2 This test method is applicable to all currently available textured geomembranes that are deployed as manufactured geomembrane sheets.
