Abstract

The melt flow rate of Standard Reference Material (SRM) 1474c, a linear polyethylene (narrow MWD ethylene-hexene copolymer) resin, was determined to be 5.04 g/10 min at 190 °C under a load of 2.16 kg using the ASTM Method D 1238-23a. The average is a result from 30 determina-tions on samples with a standard deviation of 0.016 g/10 min. The overall expanded uncertainty, including type A and type B uncertainties, is estimated as 0.20 g/10 min. This document describes details of the measurement and analysis.
