ASTM WK43577

    New Practice for Destructive Testing of Factory Fabricated Geomembrane Seams

    (What is a Work Item?)

    Developed by Subcommittee: D35.10 | Committee D35 | Contact Staff Manager


    1. Scope

    1.1 This practice provides manufacturing quality control guidance for the factory seaming of fabricated geomembrane panels. This practice is not to be considered as all-encompassing since there are a large number of geomembrane types, weld types, and fabrication processes that cannot be anticipated and covered in this practice. 1.2 This practice is written for factory fabricated geomembrane panels only and does not apply for field fabrication on-site. 1.3 This practice does not cover joining of materials during the primary geomembrane manufacturing process such as the vulcanized overlaps found in EPDM sheet. 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 non-conformance with the standard. 1.5 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.

    There are currently no standards providing guidance with respect to test procedures, frequency, or proper documentation for those making factory fabricated geomembrane panels or what should be expected by those using those panels in the field. This guide is intended to aid fabricators, suppliers, purchasers, and users of fabricated panels in the testing requirements for factory created seams during fabrication of geomembrane panels.
