Significance and Use
4.1 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.
4.2 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.
1.5 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.
1.6 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.
