Bitumen and bituminous binders - Dynamic viscosity of bituminous emulsions, cut-back and fluxed bituminous binders - Rotating spindle viscometer method
This European Standard specifies a method for the determination of the dynamic viscosity of bituminous emulsions, cut-back and fluxed bituminous binders, by means of a coaxial viscometer. There are standard application temperatures quoted, although the dynamic viscosity can be measured at other temperatures if required. Similarly, viscosity is quoted at standard rates of shear, although additional measurements can be taken at varying shear rates if required.
NOTE Some bituminous materials may exhibit non-Newtonian behaviour under the conditions of this method. Since non-Newtonian viscosity values are not unique material properties, but reflect the behaviour of the fluid and the measurement system, it should be recognised that measurements made by this method may not always predict performance under the conditions of use. Comparisons between non-Newtonian viscosities should be made only for measurements under similar conditions of shear stress and shear rate.
WARNING — The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
Bitumen und bitumenhaltige Bindemittel - Dynamische Viskosität von Bitumenemulsionen, verschnittenen und gefluxten bitumenhaltigen Bindemitteln - Viskosimeter-Verfahren mit rotierender Spindel
Diese Europäische Norm legt ein Verfahren zur Bestimmung der dynamischen Viskosität von Bitumenemulsionen
sowie verschnittenen und gefluxten bitumenhaltigen Bindemitteln mittels eines Koaxialviskosimeters
fest. Es sind Standard-Anwendungstemperaturen angegeben, obgleich die dynamische Viskosität, falls
erforderlich, auch bei anderen Temperaturen gemessen werden kann. In entsprechender Weise ist die Viskosität
bei Standard-Schergeschwindigkeiten angegeben, obgleich bei veränderlichen Schergeschwindigkeiten,
falls erforderlich, zusätzliche Maßnahmen ergriffen werden dürfen.
ANMERKUNG Einige bitumenhaltige Materialien können unter den Bedingungen dieses Verfahrens nicht-newtonsches
Verhalten aufweisen. Da nicht-newtonsche Viskositätswerte keine eindeutigen Materialeigenschaften sind, sondern das
Verhalten der Flüssigkeit und des Messsystems widerspiegeln, sollte beachtet werden, dass sich aus den nach diesem
Verfahren erhaltenen Messwerten möglicherweise nicht immer die Leistung unter den Einsatzbedingungen vorhersagen
lässt. Vergleiche zwischen nicht-newtonschen Viskositäten sollten nur für Messungen angestellt werden, die unter ähnlichen
Bedingungen hinsichtlich der Schubspannung und der Schergeschwindigkeit stattfinden.
WARNUNG - Die Anwendung dieser Norm kann den Umgang mit gefährlichen Substanzen und Ausrüstungsteilen
und die Ausführung gefährlicher Arbeitsgänge einschließen. Diese Norm erhebt nicht
den Anspruch, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Es liegt in
der Verantwortung des Anwenders dieser Norm, geeignete Verhaltensregeln zur Sicherheit und Gesundheit
festzulegen und die Anwendbarkeit einschränkender Vorschriften vor der Anwendung zu
bestimmen.
Bitumes et liants bitumineux - Détermination de la viscosité dynamique des émulsions bitumineuses, des liants bitumineux fluidifiés et fluxés - Méthode du viscosimetre a mobile tournant
La présente Norme européenne prescrit une méthode de détermination de la viscosité dynamique des
émulsions bitumineuses, des liants bitumineux fluidifiés et fluxés au moyen d’un viscosimetre coaxial. Des
températures de référence sont citées dans la norme, cependant la viscosité dynamique peut etre mesurée a
d’autres températures si cela est exigé. De maniere analogue, la viscosité est évaluée pour des taux de
cisaillement précisés, cependant d’autres mesures peuvent etre réalisées avec des taux de cisaillement
variables si exigé.
NOTE Il arrive que certaines émulsions présentent un comportement non-newtonien dans les conditions de la
présente méthode. Les valeurs de viscosité non newtoniennes ne sont pas des propriétés intrinseques du matériau mais
sont l'image du comportement du fluide et des conditions de mesure. Il convient donc d’avoir a l’esprit que les mesures
effectuées par la présente méthode ne donnent pas toujours une bonne prévision des performances dans les conditions
d’utilisation. Il est conseillé de n’effectuer des comparaisons entre des viscosités non-newtoniennes que pour des
mesures effectuées sous des contraintes de cisaillement et des taux de cisaillement comparables.
AVERTISSEMENT - La mise en oeuvre de la présente norme peut impliquer l’utilisation de produits, des
manipulations et des appareillages a caractere dangereux. La présente norme européenne n'est pas censée
aborder tous les problemes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de
consulter et d'établir des regles de sécurité et d'hygiene appropriées et de déterminer l'applicabilité des
restrictions réglementaires avant utilisation.

This should be mentioned by the viscosimeter manufacturer. 3.2 shear stress force acting tangentially to a surface divided by the area of the surface, measured in units of
N. m-2, kg. m-1. s-2 or Pa 3.3 dynamic viscosity ratio between the applied shear stress and the shear rate NOTE Dynamic viscosity is the measurement of the resistance to flow of the liquid. The SI unit of dynamic viscosity is the Pascal.second (Pa.s), the milliPascal.second (mPa.s) is a frequently used sub-unit. 3.4 Newtonian fluid fluid having a viscosity that is independent of the rate of shear
EN 14896:2006 (E) 5 NOTE The ratio of the shear stress to the shear rate is the viscosity of the fluid. If this ratio is not constant the liquid is non-Newtonian. Many fluids exhibit both Newtonian and non-Newtonian behaviour depending on the temperature and the shear rate. 3.5 form factor specific factor or factors applied for individual equipment in order to obtain the actual viscosity from the readings, mainly due to t
