Designation:D717606(Reapproved 2018)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,canals,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 unreinforcedflexible 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 Thetestsareintendedtoensurequalityandperformance,and are not intended for design purposes.Testshave been selected to be conducted primarily with liquids thatsimulate the environment to which the membrane will besubjected during actual use.The test and property limits usedto characterize the sheet are values intended to ensure mini-mum quality for the intended purpose.In-place design criteriasuch as material compatibility,chemical resistance,amongothers,are factors that shall be considered but are beyond thescope of this 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,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: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 Geosynthetics1This 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 July 1,2018.Published July 2018.Originally published2006.Last previous edition approved 2011 as D7176 06(2011).DOI:10.1520/D7176-06R18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 D5747/D5747M Practice for Tests to Evaluate the ChemicalResistance of Geomembranes to LiquidsG160 Practice for Evaluating Microbial Susceptibility ofNonmetallic Materials By Laboratory Soil Burial3.Terminology3.1 DefinitionsDefinitions are in accordance with Termi-nology D443
