11. Procedure C— Automatically Timed Flow Rate
Measurement for High Flow Rate Polyolefins Using
“Half” Die
11.1 Procedure:
11.1.1 Install/enable the automatic timing device on the
extrusion plastometer.
11.1.2 Select conditions of temperature and load from 8.2 or
in accordance with material specifications. Where multiple test
conditions exist, test conditions shall be agreed upon by the
cooperating laboratories. A melt density value (not bulk density)
for the material is required if MFR is to be calculated from
the results.
