ASTM D 7272 : 2006 : R2018

1.1This test method describes destructive quality control and/or quality assurance tests to determine the integrity of seams produced using taped seaming methods. This test method presents the procedures used for determining the quality of taped seams subjected to both peel and shear tests. These test procedures are intended for nonreinforced and reinforced geomembranes.

1.2The types of tape seaming techniques used to construct geomembrane seams include the following:

1.3For nondestructive test methods, see Practice D4437/D4437M.

1.4This test method is applicable for seaming processes that use tape adhesive as a seaming mechanism.

1.5Subsequent decisions as to seam acceptance criteria are made according to the site-specific contract plans, specifications, and contractor quality control/contractor quality assurance (CQC/CQA) documents.

1.6In case of a material-specific test method, this test method shall take precedence.

1.7Hazardous Materials—Always consult the proper material safety data sheets for any hazardous material used for the proper ventilation and protection. The use of the oven in these test methods, in this practice, may accelerate fume production from the test specimen.

1.8The values stated in both inch-pound and SI units are to be regarded separately as the standard. Values in parentheses are for information only.

1.9This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
