Over deze norm
1.1 This practice is intended for use as a summary of nondestructive quality control test methods for determining the integrity of seams used in the joining of flexible sheet materials in a geotechnical application. This practice outlines the test procedures available for determining the quality of bonded seams. Any one or combination of the test methods outlined in this practice can be incorporated into a project specification for quality control. These test methods are applicable to manufactured flexible polymeric membrane linings that are scrim reinforced or nonreinforced. This practice is not applicable to destructive testing. For destructive test methods look at other ASTM Standards and Practices.
1.2 The types of seams covered by this practice include the following: Thermally Bonded Seams, Hot Air, Hot Wedge (or Knife), Extrusion, Solvent Bonded Seams, Bodied Solvent Bonded Seams, Adhesive Bonded or Cemented Seams, Taped Seams, Waterproofed Sewn Seams.
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 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.
