significance And Use:

4.1 The use of nonreinforced geomembranes as barrier materials has created a need for a test method to evaluate the quality of chemical fusion seams produced by methods other than thermal fusion.... View More

scope:

1.1 This test method describes destructive quality control and quality assurance tests used to determine the integrity of geomembrane seams produced by adhesive and chemical fusion methods. These test procedures are intended for nonreinforced geomembranes only. This test method utilizes two sampling techniques; Method A is for seams produced without a testing flap, while Method B is for seams that produce a testing flap.

1.2 The rationale behind the two methods is that most seaming processes produce some type of flap on the back side or front side, or both, of the seam to perform peel testing. However, there are some processes in the industry that do not produce any type of flap to perform seam peel testing, and this is where the additional method is needed.

1.3 This method is intended for use with polyvinyl chloride (PVC)-based material seams, but is not limited to PVC.

1.4 Units-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 nonconformance with the standard.

1.5 Hazardous Materials-Always consult the proper Material Safety Data Sheets for any hazardous materials used for proper ventilation and protection.

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

1.7 This 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.
