1、Designation:D5747/D5747M21Standard Practice forTests to Evaluate the Chemical Resistance ofGeomembranes to Liquids1This standard is issued under the fixed designation D5747/D5747M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the y
2、ear of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers procedures for the testing ofgeomembranes for chemical resistance with liquid wastes,prepared c
3、hemical solutions,and leachates derived from solidwastes.1.2 This practice covers procedures for testing semi-crystalline,amorphous,elastomeric,and fabric-reinforcedgeomembranes.1.3 This practice is intended to be used in conjunction withPractice D5322 or D5496,or both.The scope of this practice isl
4、imited to testing and reporting procedures for unexposed andexposed geomembrane samples.1.4 Evaluation and interpretation of test data are beyond thescope of this practice.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach s
5、ystem are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use
