2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard guide provides recommendations for theselection of appropriate test methods for Ethylene
3、PropyleneDiene Terpolymer (EPDM) geomembranes used in geotechni-cal and geoenvironmental applications.1.2 This guide includes test methods for three differenttypes of EPDM geomembranes including; scrim-reinforcedmembranes, composite membranes and smooth, non-reinforced membranes.1.3 The test methods
4、 are divided into three categoriesincluding manufacturing quality control, optional performancetests and seam testing.1.4 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are provided forinformation purposes only.1.5 This standard does not purport to a
