Plastics - Determination of the melt mass-flow rate (MFR) and the melt volume-flow rate (MVR) of thermoplastics (ISO 1133:2005)
ISO 1133:2005 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. One is a mass-measurement method. The other 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 ISO 1133. The test conditions normally used for thermoplastics are listed in annexes.
These methods are in principle also applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena such as hydrolysis, condensation or crosslinking, 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, these methods are not appropriate. In such cases, the use of the viscosity number in dilute solution, determined in accordance with the relevant part of ISO 1628, is recommended for characterization purposes.
Kunststoffe - Bestimmung der Schmelze-Massefließrate (MFR) und der Schmelze-Volumenfließrate (MVR) von Thermoplasten (ISO 1133:2005)
Dieses Dokument legt zwei Verfahren für die Bestimmung der Schmelze-Massefließrate (MFR) und der Schmelze-Volumenfließrate (MVR) von thermoplastischen Materialien unter festgelegten Bedingungen für Temperatur und Belastung fest. Verfahren A dient zum Bestimmen der Masse. Verfahren B ist ein Messverfahren für die Weglänge. Üblicherweise sind die Prüfbedingungen für die Messung der Schmelze-Massefließrate oder Schmelze-Volumenfließrate in der Werkstoffnorm mit einem Verweis auf dieses Dokument festgelegt. Die üblicherweise für Thermoplaste angewendeten Bedingungen sind in den Anhängen A und B aufgelistet.
Die MVR erweist sich beim Vergleichen von Werkstoffen mit unterschiedlichen Füllstoffanteilen und beim Vergleichen von gefüllten und ungefüllten Thermoplasten als besonders nützlich. Die MFR kann, falls die Dichte der Schmelze bei der Prüftemperatur und dem Prüfdruck bekannt ist, aus automatischen MVR-Messungen bestimmt werden.
Diese Verfahren sind im Prinzip auch anwendbar auf Thermoplaste, deren rheologisches Verhalten während der Messung durch z. B. Hydrolyse, Kondensation oder Vernetzung beeinflusst wird, jedoch nur dann, wenn diese Beeinflussung begrenzt ist und wenn die Wiederhol- und Vergleichpräzision innerhalb des zulässigen Bereiches liegen. Für Werkstoffe, die bei der Prüfung ein deutlich beeinflusstes rheologisches Verhalten aufweisen, ist diese Prüfung nicht geeignet. In diesen Fällen wird empfohlen, zur Kennzeichnung die Viskositätszahl in verdünnter Lösung, bestimmt nach dem entsprechenden Titel von ISO 1628, zu verwenden.
ANMERKUNG Die Schergeschwindigkeiten in diesen Verfahren sind wesentlich kleiner als diejenigen unter normalen Verarbeitungsbedingungen, und daher korrelieren die Ergebnisse, die mit diesen Verfahren für die verschiedenen Thermoplaste erhalten wurden, nicht immer mit ihrem Verhalten bei der Verarbeitung. Beide Verfahren werden in erster Linie zur Qualitätskontrolle verwendet.
Plastiques - Détermination de l'indice de fluidité à chaud des thermoplastiques, en masse (MFR) et en volume (MVR) (ISO 1133:2005)
L'ISO 1133:2005 spécifie deux modes opératoires pour la détermination de l'indice de fluidité à chaud des matériaux thermoplastiques, en masse (MFR) et en volume (MVR), dans des conditions définies de température et de charge. Le mode opératoire A est une méthode de mesurage de la masse, le mode opératoire B une méthode de mesurage du volume déplacé. En principe, les conditions d'essai pour la détermination du MFR sont spécifiées dans la norme relative au matériau avec une référence à l'ISO 1133. Les conditions normalement utilisées pour l'essai des matériaux thermoplastiques sont résumées dans les annexes.
Ces méthodes sont en principe également applicables aux thermoplastiques dont le comportement rhéologique pendant le mesurage est affecté de manière limitée par des phénomènes tels que l'hydrolyse, la condensation et la réticulation mais uniquement si la répétabilité et la reproductibilité sont comprises dans des limites acceptables pour ces méthodes. Elles ne s'appliquent pas aux matières dont le comportement rhéologique varie de façon significative pendant les essais. Dans ce cas, il est recommandé de procéder à la caractérisation en utilisant l'indice de viscosité en solution diluée conformément à la partie pertinente de l'ISO 1628.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1133 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical
properties.
This fourth edition cancels and replaces the third edition (ISO 1133:1997), in which the clauses relating to
temperature control have been revised. In addition, the clarity of the text has been improved.

INTERNATIONAL STANDARD ISO 1133:2005(E)
Plastics — Determination of the melt mass-flow rate (MFR) and
the melt volume-flow rate (MVR) of thermoplastics
1 Scope
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
Annexes A and B.
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 provided
the melt density at the test temperature and pressure is known.
These methods are in principle also applicable to thermoplastics for which the rheological behaviour is
affected during the measurement by phenomena such as hydrolysis, condensation or crosslinking, 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, these methods are not
appropriate. In such cases, the use of the viscosity number in dilute solution, determined in accordance with
the relevant part of ISO 1628, is recommended for characterization purposes.
NOTE The rates of shear in these methods are much smaller than those used under normal conditions of processing,
and therefore data obtained by these methods for various thermoplastics may not always correlate with their behaviour
during processing. Both methods are used primarily in quality control.
