1、Designation:D588911Standard Practice forQuality Control of Geosynthetic Clay Liners1This standard is issued under the fixed designation D5889;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 paren
2、theses 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 manufacturing quality controlof geosynthetic clay liners(GCLs),describing types of tests,the proper test methods,and the minimum
3、testing frequencies.1.2 This practice is intended to aid manufacturers,suppliers,purchasers and users of GCLs in establishing a minimum levelof effort for manufacturing quality control.1.3 This practice does not address manufacturing qualityassurance,product acceptance testing,or conformance testing
4、.These are independent activities taken by organizations otherthan the GCL manufacturer.1.4 The values stated in SI units are to be regarded as thestandard.The inch-pound units given in parentheses are forinformation only.1.5 This standard does not purport to address all of thesafety concerns,if any
5、,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:2D882 Test Method for Tensile Properties of Thin Plasti
