Designation:D761310Standard Specification forFlexible Polypropylene Reinforced(fPP-R)andNonreinforced(fPP)Geomembranes1This standard is issued under the fixed designation D7613;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 flexible polypropylene rein-forced(fPP-R)and nonreinforced(fPP)geomembranes madefrom flexible polypropylene as the principal polymer preparedby the polymerization of propylene with or without other alphaolefin monomers.1.2 The tests and property limits used to characterize thesheet are values intended to ensure minimum quality.In-placesystem design criteria,such as field-seaming strength andmaterial compatibility among others,are factors that should beconsidered but are beyond the scope of this specification.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 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:2D573 Test Method for RubberDeterioration in an AirOvenD751 Test Methods for Coated FabricsD883 Terminology Relating to PlasticsD1004 Test Method for Tear Resistance(Graves Tear)ofPlastic Film and SheetingD1204 Test Method for Linear Dimensional Changes ofNonrigid Thermoplastic Sheeting or Film at ElevatedTemperatureD2136 Test Method for Coated FabricsLow-TemperatureBend TestD4439 Terminology for GeosyntheticsD4833 Test Method for Index Puncture Resistance ofGeomembranes and Related ProductsD5199 Test Method for Measuring the Nominal Thicknessof GeosyntheticsD5538 PracticeforThermoplasticElastomersTerminology and AbbreviationsD5884 Test Method for Determining Tearing Strength ofInternally Reinforced GeomembranesD6636 Test Method for Determination of Ply AdhesionStrength of Reinforced GeomembranesD6693 Test Method for Determining Tensile Properties ofNonreinforced Polyethylene and Nonreinforced FlexiblePolypropylene GeomembranesD7004 Test Method for Grab Tensile Properties of Rein-forced GeomembranesG151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG154 Practice for Operating Fluorescent LightApparatus forUV Exposure of Nonmetallic MaterialsG155 Practice for Operating Xenon Arc Light Apparatus forExposure of Non-Metallic Materials3.Terminology3.1 DefinitionsFor definitions of terms used in this speci-fication,refer to Terminologies D883 and D4439 and PracticeD5538.4.Materials and Manufacture4.1 The sheet shall be capable of being heat welded,fused,or adhesively bonded to itself for making watertight fieldsplices and repairs.4.2 Geomembrane can be nonreinforced or reinforced withfabric or scrim.5.Chemical Composition5.1 The geomembrane shall be formulated from virginflexible polypropylene,in amounts greater than 85%,byweight of the total polymer content.The remaining 15%shallbe comprised of compatible polymers or pigments or both,stabilizers,and colorants that are suitably compounded to1This 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 Sept.15,2010.Published October 2010.DOI:10.1520/D7613-10.2For 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 specifications Document Summary pageon the ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 satisfy the physical requirements in the specification(seePractice D5538 for definitions).NOTE1The compound shall not contain postconsumer(PCR)com-ponents containing bitumen or any other ingredients that could interferewith the long-term stability of the geomembrane.No more than 10%rework resin is allowed for the production of the membrane and shall befully compatible with the parent material.6.Physical Properties6.1 Each sheet specimen shall meet or exceed the physicalrequirements prescribed in Table 1.6.2 The tolerance for time conditions(aging,weathering,and so forth)is 615 min or 61%of the period,whichever isgreater,unless otherwise specified.6.3 The tolerance for temperature conditions(aging and soforth)is 62C of the specified temperature,unless otherwisespecified.7.Dimensions,Mass,and Permissible Variations7.1 The width and length of the sheet shall be agreed uponbetween the purchaser and the supplier.7.2 The tolerance for both width and length sha
