1.1This test procedure is based significantly on the GRI GG7 test procedure, Carboxyl End Group Content of Polyethylene Terephthalate (PET) Yarns.
1.2 This test method is used to determine the concentration, in mmol/Kg, of carboxyl end groups (CEG) found in poly(ethylene terephthalate) (PET) yarns by titration.
1.3This test is applicable to geogrid yarns that are made from PET resin.
Note 1:This test is also applicable to high strength geotextile yarns that are made from PET and are used in reinforcement applications.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
