Kunststoffe - Bestimmung der Schmelze-Massefließrate (MFR) und der Schmelze-Volumenfließrate (MVR) von Thermoplasten - Teil 1: Allgemeines Prüfverfahren (ISO 1133-1:2011)
Dieser Teil der ISO 1133 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-Fließrate in
der Werkstoffnorm mit einem Verweis auf diesen Teil der ISO 1133 festgelegt. Die üblicherweise für
Thermoplaste angewendeten Bedingungen sind im Anhang A aufgelistet.
Die MVR erweist sich beim Vergleichen von Werkstoffen mit unterschiedlichen Füllstoffgehalten und beim
Vergleichen von gefüllten und ungefüllten Thermoplasten als besonders nützlich. Die MFR kann, falls die
Dichte der Schmelze bei der Prüftemperatur bekannt ist, aus MVR-Messungen bestimmt werden, oder
umgekehrt.
Dieser Teil der ISO 1133 ist 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 Vergleichspräzision innerhalb des
zulässigen Bereiches liegen. Für Werkstoffe, die bei der Prüfung ein deutlich beeinflusstes rheologisches
Verhalten aufweisen, ist dieser Teil der ISO 1133 nicht geeignet. In diesen Fällen gilt ISO 1133-2.
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) - Partie 1: Méthode normale (ISO 1133-1:2011)
L'ISO 1133-1:2011 spécifie deux modes opératoires pour la détermination de l'indice de fluidité à chaud en masse (MFR) et en volume (MVR) des matériaux thermoplastiques, 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 est une méthode de mesurage du volume déplacé. En principe, les conditions d'essai pour la détermination de l'indice de fluidité à chaud sont spécifiées dans la norme relative au matériau avec une référence à l'ISO 1133-1:2011. Les conditions normalement utilisées pour l'essai des matériaux thermoplastiques sont énumérées en annexe.
Le MVR est particulièrement utile pour comparer des matériaux à teneur en charges différentes et pour comparer des thermoplastiques chargés avec ceux non chargés. Le MFR peut être déterminé à partir de mesurages MVR, ou inversement, à condition que la masse volumique à l'état fondu à la température d'essai soit connue.
L'ISO 1133-1:2011 peut également être applicable aux thermoplastiques dont le comportement rhéologique est affecté pendant le mesurage par des phénomènes tels que l'hydrolyse (scission de la chaîne), la condensation et la réticulation, mais uniquement si cet effet est d'ampleur limitée et seulement si la répétabilité et la reproductibilité sont comprises dans des limites acceptables. L'ISO 1133-1:2011 n'est pas appropriée aux matériaux dont le comportement rhéologique varie de façon significative pendant les essais. Dans de tels cas, l'ISO 1133-2 s'applique.
Polimerni materiali - Ugotavljanje masnega (MFR) in prostorninskega pretoka taline (MVR) plastomerov - 1. del: Standardna metoda (ISO 1133-1:2011)
Ta del standarda ISO 1133 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 del standarda ISO 1133. 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 del standarda ISO 1133 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 del standarda ISO 1133 ni primeren. V takih primerih se uporablja standard ISO 1133-2.

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 1133-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical
properties.
This first edition of ISO 1133-1 cancels and replaces ISO 1133:2005. It also incorporates the Technical
Corrigendum, ISO 1133:2005/Cor.1:2006.
In this part of ISO 1133, changes have been made to accommodate ISO 1133-2. In addition: Clause 3 includes
further definitions relevant to both parts of ISO 1133; 5.1.3 specifies the lower edge of the piston head; 5.1.4
updates temperature tolerances; 5.2.1.7 on a preforming device has been added; 5.2.2.2 includes revised
cut-off timing accuracy; 8.3 provides cut-off time intervals that are consistent with other specifications in this
part of ISO 1133; 8.5.3 and 9.6.3 have been included on expression of half die results; 9.3 provides minimum
piston displacements that are consistent with other specifications in this part of ISO 1133; Annex B has been
simplified to avoid inconsistencies between this and the materials specification standa
