Scope

1.1 This test method covers an accelerated, destructive test method for geomembranes in a geotechnical application.

1.2 This test is applicable to field fabricated geomembranes that are scrim reinforced or non reinforced.

1.3 This test method is applicable for field seaming processes that use a chemical fusion agent or bodied chemical fusion agent, as the seaming mechanism.

1.4 Subsequent decisions as to seam acceptance criteria are made according to the site-specific contract plans, specification and CQC/CQA documents.

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

1.6 Hazardous Materials—Always consult the proper Material Safety Data Sheets for any Hazardous materials used for proper ventilation and protection. The use of the oven in this test method may accelerate fume production from the test specimen.

1.7 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 applicable of regulatory limitations prior to use.

Significance and Use

Significance— The increased use of geomembranes as barrier materials to restrict fluid migration from one location to another in various applications, and the various types of seaming methods used in joining geomembrane sheets, has created a need to standardize tests by which the various seams can be compared and the quality of the seam systems can be evaluated. This test method is intended to meet such a need.

Use—Accelerated seam test provides information as to the status of the field seam. Data obtained by this test method should be used with site-specific contract plans, specification and CQC/CQA documents. This test method is useful for specification testing and for comparative purposes, but does not necessarily measure the ultimate strength that the seam may acquire.
