ASTM D7865-13 (R2021) pdf free download.Standard Guide for ldentification, Packaging, Handling, Storage, and Deployment of Fabricated Geomembrane Panels.
1.1 This guide covers guidelines for the identification, packaging, handling, storage, and deployment of fabricated a geomembrane panels. This guide is not to be considered as all encompassing since each project involving fabricated panels presents its own challenges and special conditions.
1.2 This guide is intended to aid fabricators, suppliers, purchasers. and users of fabricated panels in the identification, packaging, handling, storage, and deployment of fabricated geomembrane panels.
1.3 This guide is written for factory-fabricated geomembrane panels only. Other geosynthetics use Guide D48731 D4873M as their guide.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this Standard.
3. Terminology
3. 1 Definitions:
3.1.1 Some with terms applying to this guide appear in Terminology D4439.
3. 1 .2 accordion-folded (slid rolled J)(snel, n—refers to an accordion-folded fabricated panel that is first accordion-folded to the desired width and then rolled to form a finished, rolled bundle for transport.
3. 1 .3 accordion-folded panel, n—refers to a fabricated panel where the material is folded back and fbrth in a formation in the same principal direction as the seams. This folding takes a wider panel of material and makes it into a narrow stack. For example. a 30 m by 30 m prefabricated panel could he accordion-folded into a 3 m wide stack of material ten layers deep and 30 m long.
3. 1 .4 double accordion-folded panel, n—refers to an accordion-folded fabricated panel that is accordion-folded to the desired width and then accordion-folded in the length direction onto a pallet (or into a container). Double accordion- folded panels typically appear as a “cube” of material with square corners.
3. 1 .5 fabricated panel, n—refers to a geomemhrane panel seamed at a fabrication facility into a larger panel than the original roll stock material. A fabricated panel may be a larger rectangular panel of geomembrane or may be a specific fabricated shape or may contain special job-specific detail work.
3. 1 .6 rolled panel, n—refers to a fabricated panel that is rolled from OflC end or in some cases from both ends to the middle.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 flibricato,; n—the person or organization by whom the geomembrane material is fabricated into a fabricated panel.
4. Significance and Use
4.1 For a fabricated panel to be properly used, it must be adequately identified and packaged.ASTM D7865 pdf download.
