This International Standard 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 International Standard. The test conditions normally used for thermoplastics are listed in Annex A. The MVR will be found 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 visa versa, provided the melt density at the test temperature is known. This part may also be applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena such as hydrolysis (chain scission), condensation, cross-linking, but only if the effect is limited in extent and only if the repeatability and reproducibility are within an acceptable range. Formaterials which show significantly affected rheological behaviour during testing, this part is not appropriate. In such cases ISO 1133 part 2 should be used.
