Certification of Standard Reference Material 1474a, A Polyethylene Resin
J R. Maurey, Kathleen M. Flynn, Charles M. Guttman
The melt flow rate of Standard Reference Material (SRM) 1474a, a linear polyethylene (narrow MWD ethylene-hexene copolymer) resin, was determined to be 5.10 g/10 min at 190 OC under a load of 2.16 kg using the ASTM Method D 1238-00. The average results from 45 determinations on samples with a standard deviation of 0.056 g/10 min. The overall expanded uncertainty, including type A and type B uncertainties, is estimated as 0.42 g/10 min.
