Designation:D786513Standard Guide forIdentification,Packaging,Handling,Storage andDeployment of Fabricated Geomembrane Panels1This standard is issued under the fixed designation;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()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 astheir 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D4439 Terminology for GeosyntheticsD4873 Guide for Identification,Storage,and Handling ofGeosynthetic Rolls and Samples3.Terminology3.1 Definitions:Some with terms applying to this guideappear in Terminology D4439.3.1.1 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.3.1.2 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 10 layersdeep and 30 m long.3.1.3 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.3.1.4 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.3.1.5 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 notdegraded.Failure to follow good practice may result in theunnecessary failure of the fabricated panel in a properlydesigned application.4.2 This guide is not intended to replace project-specificstorage,handling,identification,packaging,or installationrequirements or quality assurance programs.1This guide is under the jurisdiction ofASTM Committee D35 on Geosyntheticsand is the direct responsibility of Subcommittee D35.10 on Geomembranes.Current edition approved July 1,2013.Published July 2013.DOI:10.1520/D7865132For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Procedure5.1 Fabrication and Identification:5.1.1 Fabricated geomembrane panels are seamed to thecustomer-specified sizes according to previously agreed speci-fications.If a project layout is required then the fabricatedpanel is prepared according to the project layout.Specialfabricated panels such as shaped panels or panels with fittingsshould be fabricated according to customer-approved draw-ings.5.1.2 All fabricated geomembrane panels should beuniquely identified with a number or other identificationmarkings.These identification markings should clearly identifywhere the panel will be placed in any project layout.5.1.3 Identify each fabricated geomembrane panel with adurable,gummed weather resistant label,or equivalent.Onelabel should b
