Designation:D786513(Reapproved 2021)Standard Guide forIdentification,Packaging,Handling,Storage,andDeployment of Fabricated Geomembrane Panels1This standard is issued under the fixed designation D7865;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers guidelines for the identification,packaging,handling,storage,and deployment of fabricatedgeomembrane panels.This guide is not to be considered as allencompassing since each project involving fabricated panelspresents 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 fabricatedgeomembrane panels.1.3 This guide is written for factory-fabricated geomem-brane panels only.Other geosynthetics use Guide D4873/D4873M as their guide.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D4439 Terminology for GeosyntheticsD4873/D4873M Guide for Identification,Storage,and Han-dling of Geosynthetic Rolls and Samples3.Terminology3.1 Definitions:3.1.1 Some with terms applying to this guide appear inTerminology D4439.3.1.2 accordion-folded and rolled panel,nrefers to anaccordion-folded fabricated panel that is first accordion-foldedto the desired width and then rolled to form a finished,rolledbundle for transport.3.1.3 accordion-folded panel,nrefers to a fabricated panelwhere the material is folded back and forth in a“Z”formationin the same principal direction as the seams.This folding takesa wider panel of material and makes it into a narrow stack.Forexample,a 30 m by 30 m prefabricated panel could beaccordion-folded into a 3 m wide stack of material ten layersdeep and 30 m long.3.1.4 double accordion-folded panel,nrefers to anaccordion-folded fabricated panel that is accordion-folded tothe desired width and then accordion-folded in the lengthdirection onto a pallet(or into a container).Double accordion-folded panels typically appear as a“cube”of material withsquare corners.3.1.5 fabricated panel,nrefers to a geomembrane panelseamed at a fabrication facility into a larger panel than theoriginal roll stock material.A fabricated panel may be a largerrectangular panel of geomembrane or may be a specificfabricated shape or may contain special job-specific detailwork.3.1.6 rolled panel,nrefers to a fabricated panel that isrolled from one end or in some cases from both ends to themiddle.3.2 Definitions of Terms Specific to This Standard:3.2.1 fabricator,nthe person or organization by whom thegeomembrane material is fabricated into a fabricated panel.4.Significance and Use4.1 For a fabricated panel to be properly used,it must beadequately identified and packaged.It must be handled andstored in such a way that its physical property values are not1This guide is under the jurisdiction ofASTM Committee D35 on Geosyntheticsand is the direct responsibility of Subcommittee D35.10 on
