ISO 1133-1 Melt Flow Index Testing of Plastics
Extrusion plastometers provide standard values for the melt flow index (MFR) and volume flow index (MVR) of filled and unfilled thermoplastics according to ISO 1133-1and ISO 1133-2, ASTM D1238 and other similar standards.
The ISO 1133-1 standard establishes the general test method for determination of melt mass-flow rates (MFR) and melt volume-flow rates (MVR) of thermoplastics.
