Certification of Standard Reference Material 1473b, Low Density Polyethylene Resin

摘要

The melt flow rate of Standard Reference Material (SRM) 1473b Low Density Polyethylene Resin was determined to be 1.13 g/10 min at 190 deg C under a load of 2.16 kg using the ASTM Method D 1238-00. The average results from 48 determinations on samples with a standard deviation of 0.013 g/10 min. The overall expanded uncertainty, including type A and type B uncertainties, is estimated as 0.098 g/10 min.
