Plastic-determination of the melt mass flow rate(MFR) and melt volume -flow rate(MVR) of thermoplastics
ISO1133: This part of ISO 1133 specifies two procedures for the determination of the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of thermoplastic materials under specified conditions of temperature and load.
ASTM D1238:This test method covers the determination of the rate of extrusion of molten thermoplastic resins using an extrusion
plastometer. After a specified preheating time, resin is extruded through a die with a specified length and orifice diameter under
prescribed conditions of temperature, load, and piston position in the barrel.
ASTM D3364:This test method is an extension of Test Method D1238 specific to the measurement of flow rates of poly(vinyl chloride) (PVC) compounds while detecting and controlling various polymer instabilities associated with the flow rate
