Designation:D532217Standard Practice forLaboratory Immersion Procedures for Evaluating theChemical Resistance of Geosynthetics to Liquids1This standard is issued under the fixed designation D5322;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 covers laboratory immersion proceduresfor the testing of geosynthetics for chemical resistance to liquidwastes,prepared chemical solutions,and leachates derivedfrom solid wastes.1.2 This standard is not applicable to some geosyntheticssuch as geosynthetic clay liners(GCLs),because of theircomposite nature requiring a confining pressure during immer-sion.However,individual geosynthetic components of theGCL can be tested.1.3 This standard was originally developed to supplementand expand EPA 9090 to include all geosynthetics.EPA 9090has not been updated since 1992.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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.For specific hazardsstatements,see Section 7.1.6 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 TextilesD471 Test Method for Rubber PropertyEffect of LiquidsD543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD4439 Terminology for GeosyntheticsD5496 Practice for In Field Immersion Testing of Geosyn-theticsD5747 Practice for Tests to Evaluate the Chemical Resis-tance of Geomembranes to Liquids3.Terminology3.1 Definitions:For definitions of many terms used in thispractice,refer to Terminologies D123 and D4439.3.2 Definitions of Terms Specific to This Standard:3.2.1 chemical resistancethe ability to resist chemicalattack.3.2.1.1 DiscussionThe attack is dependent on the testmethod,and its severity is measured by determining thechanges in physical properties.Time,temperature,stress,andreagent may all be factors affecting the chemical resistance ofa material.3.2.2 geosynthetic,na planar product manufactured frompolymeric material used with soil,rock,earth,or other geo-technical engineering-related material as an integral part of aman-made project,structure,or system.4.Significance and Use4.1 This practice provides a standard immersion procedurefor investigating the chemical resistance of a geosynthetic to aliquid waste,leachate,or chemical in a laboratory environ-ment.The conditions specified in this practice are intendedboth to provide a basis of standardization and to serve as aguide for those wishing to compare or investigate the chemicalresistance of a geosynthetic material(s)in a laboratory envi-ronment.Practice D5496 can be used should the user need toassess the performance of a geosynthetic in field conditions.4.2 This practice is not intended to establish,by itself,thebehavior of geosynthetics when exposed to liquids.Suchbehavior,referred to as chemical resistance,can be definedonly in terms of specific chemical solutions and methods oftesting and evaluation criteria selected by the user.1This 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 June 1,2017.Published June 2017.Originallyapproved in 1992.Last previous edition approved in 2009 as D5322 98(2009).DOI:10.1520/D5322-17.2For 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 5.Apparatus5.1 Exposure Tank,for containment of the solution and testmaterial.The tank must be chemically resistant and imperme-able to the solution being used.Stainless steel or glass isrecommended.Glass should not be used with strongly basicso
