Plastics - Determination of the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of thermoplastics - Part 1: Standard method (ISO 1133-1:2022)

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.

Kunststoffe - Bestimmung der Schmelze-Massefließrate (MFR) und der Schmelze-Volumenfließrate (MVR) von Thermoplasten - Teil 1: Allgemeines Prüfverfahren (ISO 1133-1:2022)

Dieses Dokument legt zwei Verfahren für die Bestimmung der Schmelze Massefließrate (MFR, en: melt mass flow rate) und der Schmelze Volumenfließrate (MVR, en: melt volume flow rate) von thermoplastischen Werkstoffen 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 Fließrate in der Werkstoffnorm mit einer Verweisung auf dieses Dokument festgelegt. Die üblicherweise für Thermoplaste angewendeten Prüfbedingungen sind in Anhang A aufgeführt.
Die MVR ist für den Vergleich von Werkstoffen mit unterschiedlichen Füllstoffgehalten und für den Vergleich von gefüllten und ungefüllten Thermoplasten besonders nützlich. Die MFR kann anhand von MVR Messungen bestimmt werden, oder umgekehrt, wenn die Dichte der Schmelze bei der Prüftemperatur bekannt ist.
Dieses Dokument ist möglicherweise auch auf Thermoplaste anwendbar, deren rheologisches Verhalten während der Messung z. B. durch Hydrolyse (Kettenspaltung), Kondensation und Vernetzung beeinflusst wird, jedoch nur dann, wenn diese Beeinflussung begrenzt ist und wenn die Wiederhol  und Vergleichpräzision innerhalb eines zulässigen Bereiches liegen. Für Werkstoffe, die bei der Prüfung ein deutlich beeinflusstes rheologisches Verhalten aufweisen, ist dieses Dokument nicht geeignet. In diesen Fällen gilt ISO 1133 2.
ANMERKUNG   Die Schergeschwindigkeiten bei diesen Verfahren sind wesentlich geringer als diejenigen, die unter den üblichen Verarbeitungsbedingungen angewendet werden, weshalb es möglich ist, dass die Daten, die mit diesen Verfahren für die verschiedenen Thermoplaste erhalten wurden, nicht immer mit ihrem Verhalten bei der Verarbeitung korrelieren. Beide Verfahren werden in erster Linie zur Qualitätskontrolle angewendet.
WARNUNG — Personen, die dieses Dokument anwenden, sollten gegebenenfalls mit der üblichen Laborpraxis vertraut sein. Dieses Dokument erhebt nicht den Anspruch, alle gegebenenfalls mit seiner Anwendung verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders, geeignete Vorkehrungen für den Arbeits- und Gesundheitsschutz zu treffen und die Einhaltung jeglicher gesetzlicher Bestimmungen sicherzustellen.

Plastiques - Détermination de l'indice de fluidité à chaud des thermoplastiques, en masse (MFR) et en volume (MVR) - Partie 1: Méthode normale (ISO 1133-1:2022)

Polimerni materiali - Ugotavljanje masnega (MFR) in prostorninskega pretoka taline (MVR) plastomerov - 1. del: Standardna metoda (ISO 1133-1:2022)

Ta dokument določa dva postopka za ugotavljanje masnega (MFR) in prostorninskega (MVR) pretoka taline plastomerov pod določenimi pogoji temperature ter obremenitve. Postopek A je metoda za merjenje mase. Postopek B je metoda za merjenje premika. Običajno so preskusni pogoji za merjenje pretoka taline določeni v standardu za material s sklicevanjem na ta dokument. Preskusni pogoji, ki se običajno uporabljajo za plastomere, so navedeni v dodatku A. Prostorninski pretok taline je zlasti uporaben pri primerjavi materialov z različno vsebnostjo polnila in primerjavi polnjenih plastomerov z nepolnjenimi. Masni pretok taline je mogoče ugotoviti z meritvami prostorninskega pretoka taline ali obratno, če je gostota taline pri preskusni temperaturi znana. Ta dokument je morda mogoče uporabiti tudi za plastomere, pri katerih se reološko obnašanje med merjenjem spremeni zaradi pojavov, kot so hidroliza (cepljenje verig), kondenzacija in prečno povezovanje, vendar le, če je obseg učinka omejen ter sta ponovljivost in obnovljivost v okviru sprejemljivih vrednosti. Za materiale z bistveno spremenjenim reološkim obnašanjem med preskušanjem ta dokument ni primeren. V takih primerih se uporablja standard ISO 1133-2. OPOMBA: Strižne hitrosti pri teh metodah so veliko manjše od tistih, ki se uporabljajo v običajnih pogojih predelave, zato je mogoče, da se podatki, pridobljeni za različne plastomere s tema metodama, ne bodo vedno ujemali z njihovim obnašanjem med predelavo. Obe metodi se primarno uporabljata pri preverjanju kakovosti.
