1、Designation:D761310Standard Specification forFlexible Polypropylene Reinforced(fPP-R)andNonreinforced(fPP)Geomembranes1This standard is issued under the fixed designation D7613;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、 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 specification covers flexible polypropylene rein-forced(fPP-R)and nonreinforced(fPP)geomembranes madefrom flexible
3、 polypropylene as the principal polymer preparedby the polymerization of propylene with or without other alphaolefin monomers.1.2 The tests and property limits used to characterize thesheet are values intended to ensure minimum quality.In-placesystem design criteria,such as field-seaming strength an
4、dmaterial compatibility among others,are factors that should beconsidered but are beyond the scope of this specification.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of the
