This document 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. Procedure A is a mass-measurement method. Procedure B is a displacement-measurement
method. Normally, the test conditions for measurement of melt flow rate are specified in the material
standard with a reference to this document. The test conditions normally used for thermoplastics are
listed in Annex A.
The MVR is particularly useful when comparing materials of different filler content and when
comparing filled with unfilled thermoplastics. The MFR can be determined from MVR measurements,
or vice versa, provided the melt density at the test temperature is known.
This document is also possibly applicable to thermoplastics for which the rheological behaviour is
affected during the measurement by phenomena such as hydrolysis (chain scission), condensation and
cross-linking, but only if the effect is limited in extent and only if the repeatability and reproducibility
are within an acceptable range. For materials which show significantly affected rheological behaviour
during testing, this document is not appropriate. In such cases, ISO 1133-2 applies.
NOTE The rates of shear in these methods are much smaller than those used under normal conditions of
processing, and therefore it is possible that data obtained by these methods for various thermoplastics will not
always correlate with their behaviour during processing. Both methods are used primarily in quality control. |
