Designation:D717606(Reapproved 2011)Standard Specification forNon-Reinforced Polyvinyl Chloride(PVC)GeomembranesUsed in Buried Applications1This standard is issued under the fixed designation D7176;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 specification covers polyvinyl chloride(PVC)flex-ible sheeting which is used for construction of concealedcontainment-membranes.Examples are ponds and lakes,ca-nals,reservoirs,landfill liners,covers and closures or similarinstallations where the membrane is inaccessible once theconstruction is complete.Included are requirements for mate-rials and sheeting,test methods,workmanship criteria andmethods of marking.This Specification covers un-reinforcedflexible sheet made from polyvinyl chloride(PVC)resin as theprimary polymer intended for use in geomembranes.Thisspecification covers PVC sheet 0.25 mm through 1.5 mmthickness(0.010 in.through 0.060 in.)typically used forgeomembrane linings.1.2 Reworked materials may be used in this product inaccordance with the requirements in Section 5.1.3 The tests are intended to ensure quality and performanceand are not intended for design purposes.Tests have beenselected to be conducted primarily with liquids that simulatethe environment to which the membrane will be subjectedduring actual use.The test and property limits used tocharacterize the sheet are values intended to ensure minimumquality for the intended purpose.In place design criteria suchas material compatibility,chemical resistance,among others,are factors that shall be considered but are beyond the scope ofthis specification.1.4 The values stated in metric units are to be regarded asthe standard.The values stated in parentheses(English)are forinformation only.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:2D751 Test Methods for Coated FabricsD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD882 Test Method for Tensile Properties of Thin PlasticSheetingD1004 Test Method for Tear Resistance(Graves Tear)ofPlastic Film and SheetingD1203 Test Methods for Volatile Loss From Plastics UsingActivated Carbon MethodsD1204 Test Method for Linear Dimensional Changes ofNonrigid Thermoplastic Sheeting or Film at ElevatedTemperatureD1239 Test Method for Resistance of Plastic Films toExtraction by ChemicalsD1243 Test Method for Dilute Solution Viscosity of VinylChloride PolymersD1790 Test Method for Brittleness Temperature of PlasticSheeting by ImpactD2124 Test Method for Analysis of Components in Poly(Vi-nyl Chloride)Compounds Using an Infrared Spectropho-tometric TechniqueD4439 Terminology for GeosyntheticsD5033 Guide for Development ofASTM Standards Relatingto Recycling and Use of Recycled Plastics(Withdrawn2007)3D5199 Test Method for Measuring the Nominal Thicknessof GeosyntheticsD5747 Practice for Tests to Evaluate the Chemical Resis-tance of Geomembranes to Liquids1This specification is under the jurisdiction of ASTM Committee D35 onGeosynthetics and is the direct responsibility of Subcommittee D35.10 on Geomem-branes.Current edition approved June 1,2011.Published July 2011.Originally pub-lished 2006.Last previous edition approved 2006 as D717606.DOI:10.1520/D7176-06R11.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 G160 Practice for Evaluating Microbial Susceptibility ofNonmetallic Materials By Laboratory Soil Burial3.Terminology3.1 DefinitionsDefinitions are in accordance with Termi-nology D4439 unless otherwise indicated.3.2 Definitions of Terms Specific to This Standard:3.2.1 fabricator,na company that converts geomembranerolls into panels.3.2.2 homogeneous sheeting,nsheeting that is of uniformcomposition throughout its thickness.3.2.3 manufacture,na company that processes raw mate-rials into geomembrane rolls.3.2.4 panel,na series of geomembrane sheets fabricatedtogether to make a larger unit,as supplied by a fabricatorusually folded onto a pallet or folded then rolled on a core.3.2.5 roll,na quantity of geomembrane rolled up to forma single package as supplied from the manufacturer.3.2.6 roll width,nthe width of a roll as suppli
