Designation:D638818Standard Practice forTests to Evaluate the Chemical Resistance of Geonets toLiquids1This standard is issued under the fixed designation D6388;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 practice describes procedures for testing geonetproducts for chemical resistance with liquid wastes,preparedchemical solutions,or leachates,or both,derived from solidwastes.1.2 This practice describes test methods for measuringchanges in mass,dimensions,tensile and hydraulic properties,and other optional physical and mechanical properties causedby immersion in test solutions,which may be representative ofanticipated end-use conditions.This practice may be used toassess the extent to which a products as-manufactured prop-erties are affected by such immersion.1.3 This practice is intended to be used in conjunction withPractice D5322 or D5496.The scope of this practice is limitedto testing and reporting procedures for unexposed and exposedgeonet samples.1.4 Evaluation or interpretation of test data is beyond thescope of this practice.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.See Section 7 for specific hazards statements.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:2D123 Terminology Relating to TextilesD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD1238 Test Method for Melt Flow Rates of Thermoplasticsby Extrusion PlastometerD1621 Test Method for Compressive Properties of RigidCellular PlasticsD3895 Test Method for Oxidative-Induction Time of Poly-olefins by Differential Scanning CalorimetryD4439 Terminology for GeosyntheticsD4595 Test Method for Tensile Properties of Geotextiles bythe Wide-Width Strip MethodD4716/D4716M Test Method for Determining the(In-plane)Flow Rate per Unit Width and Hydraulic Transmissivityof a Geosynthetic Using a Constant HeadD5035 Test Method for Breaking Force and Elongation ofTextile Fabrics(Strip Method)D5199 Test Method for Measuring the Nominal Thicknessof GeosyntheticsD5322 Practice for Laboratory Immersion Procedures forEvaluating the Chemical Resistance of Geosynthetics toLiquidsD5397 Test Method for Evaluation of Stress Crack Resis-tance of Polyolefin Geomembranes Using Notched Con-stant Tensile Load TestD5496 Practice for In Field Immersion Testing of Geosyn-theticsD5747/D5747M Practice for Tests to Evaluate the ChemicalResistance of Geomembranes to LiquidsD5885/D5885M Test Method for Oxidative Induction Timeof Polyolefin Geosynthetics by High-Pressure Differential1This practice is under the jurisdiction of ASTM Committee D35 on Geosyn-thetics and is the direct responsibility of Subcommittee D35.02 on EnduranceProperties.Current edition approved March 15,2018.Published April 2018.Originallyapproved in 1999.Last previous edition approved in 2012 as D6388 99(2012).DOI:10.1520/D6388-18.2For 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.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 Scanning Calorimetry2.2 EPA Standards:EPA/600/288/052 Lining of Waste Containment and OtherImpoundment Facilities3EPA 9090 Compatibility Test for Wastes and MembraneLiners43.Terminology3.1 Definitions:3.1.1 chemical resistance,nfor geosynthetics,the extentto which a material or product retains its original physical andchemical characteristics as a function of immersion in,orcontact with,a foreign substance(see Practice D5747/D5747M).3.1.2 geonet,na geosynthetic consisting of integrallyconnected parallel sets of ribs overlying similar sets at variousangles for planar drainage of liquids or gases(see TerminologyD4439).3.1.3 geosynthetic,na planar product manufactured frompolymeric mat
