Designation: D6213 − 17Standard Practice forTests to Evaluate the Chemical Resistance of Geogrids toLiquids 1This standard is issued under the f i xed designation D6213; 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 the procedures for testing ofgeogrids for chemical resistance to liquids.1.2 This practice describes methods for measuring changesin physical and mechanical properties caused by immersion intest solutions that may be representative of anticipated end-useconditions.1.3 This practice describes procedures for required andrecommended testing of geogrids.1.4 Evaluation or interpretation of test data is beyond thescope of this practice.1.5 This practice is intended to be used in conjunction withPractice D5322 or Practice D5496, or both. The scope of thispractice is limited to testing and reporting procedures forunexposed and exposed geogrid coupons.1.6 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. Specif i c precau-tionary statements are given in Section 7.1.7 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.

Summary of Practice4.1 This practice def i nes test methods and procedures forevaluating the resistance of geogrids to liquid exposure bymonitoring physical and chemical properties of geogrid cou-pons after immersion in a test liquid. The physical condition ofthe geogrid is monitored as a function of cumulative exposuretime by means of visual observations, and mechanical andchemical property tests.5. Signif i cance and Use5.1 This practice is intended to provide a list of standardprocedures for test programs investigating the chemical resis-tance of a geogrid to a liquid.
