Petroleum products - Transparent and opaque liquids - Determination of kinematic viscosity and calculation of dynamic viscosity (ISO 3104:2023)

This document specifies Procedure A, using manual glass viscometers, and Procedure B, using glass capillary viscometers in an automated assembly, for the determination of the kinematic viscosity, ν, of both transparent and opaque products. The scope includes liquid petroleum products, fatty acid methyl ester (FAME), paraffinic diesel, hydrotreated vegetable oil (HVO), gas to liquid (GTL) and biofuel diesel mixtures up to 50 % FAME. The kinematic viscosity is determined by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, is obtained by multiplying the measured kinematic viscosity by the density, ρ, of the liquid. The range of kinematic viscosities covered in this test method is from 0,2 mm2/s to 300 000 mm2/s over the temperature range –20 °C to +150 °C.
NOTE       The result obtained from this document is dependent upon the behaviour of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behaviour). If, however, the viscosity varies significantly with the rate of shear, different results can be obtained from viscometers of different capillary diameters. The procedure and precision values for residual fuel oils, which under some conditions exhibit non-Newtonian behaviour, have been included.

Mineralölerzeugnisse - Durchsichtige und undurchsichtige Flüssigkeiten - Bestimmung der kinematischen Viskosität und Berechnung der dynamischen Viskosität (ISO 3104:2023)

Dieses Dokument legt Verfahren A mit manuellen Glas-Viskosimetern und Verfahren B mit Glas-Kapillarviskosimetern in einer automatisierten Apparatur zur Bestimmung der kinematischen Viskosität ν von sowohl durchsichtigen als auch undurchsichtigen Erzeugnissen fest. Der Anwendungsbereich umfasst flüssige Mineralölerzeugnisse, Fettsäuremethylester (FAME, en: fatty acid methyl ester), paraffinischen Dieselkraftstoff, hydriertes Pflanzenöl (HVO, en: hydrotreated vegetable oil), Erzeugnisse aus Gas-to-Liquid-Prozessen (GTL, en: gas to liquid) und Biokraftstoff-Dieselkraftstoff-Mischungen mit bis zu 50 % FAME. Die kinematische Viskosität wird durch Messung der Durchflusszeit eines Flüssigkeitsvolumens unter dem Einfluss der Schwerkraft durch ein kalibriertes Glas-Kapillarviskosimeter bestimmt. Die dynamische Viskosität η wird erhalten, indem die gemessene kinematische Viskosität mit der Dichte ρ der Flüssigkeit multipliziert wird. Mit diesem Prüfverfahren werden kinematische Viskositäten von 0,2 mm2/s bis 300 000 mm2/s über einen Temperaturbereich von −20 °C bis +150 °C abgedeckt.
ANMERKUNG   Das mit diesem Dokument erhaltene Ergebnis hängt vom Verhalten der Probe ab; dieses Dokument ist für Flüssigkeiten vorgesehen, für die in erster Linie Schubspannung und Schergeschwindigkeit proportional sind (Newtonsches Fließverhalten). Wenn sich jedoch die Viskosität signifikant mit der Schergeschwindigkeit ändert, können unterschiedliche Ergebnisse mit Viskosimetern unterschiedlichen Kapillardurchmessers erhalten werden. Das Verfahren und Präzisionswerte für Rückstandsheizöle, die unter gewissen Bedingungen nicht-newtonsches Verhalten zeigen, wurden ebenfalls aufgenommen.
WARNUNG — Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme, soweit vorhanden, zu behandeln. Es liegt in der Verantwortung der Person, die das Dokument anwendet, vor der Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und die Geltung weiterer diesbezüglicher Auflagen zu prüfen.

Produits pétroliers - Liquides opaques et transparents - Détermination de la viscosité cinématique et calcul de la viscosité dynamique (ISO 3104:2023)

Le présent document spécifie un Mode opératoire A utilisant des viscosimètres manuels en verre et un Mode opératoire B utilisant des viscosimètres à capillaires en verre dans un assemblage automatisé, pour la détermination de la viscosité cinématique, ν, de produits transparents et opaques. Le domaine d'application couvre les produits pétroliers liquides, les esters méthyliques d'acides gras (EMAG), le gazole paraffinique, l'huile végétale hydrotraitée (HVO), les carburants de transformation du gaz en liquide (GTL) et les mélanges de biocarburants diesel jusqu'à 50 % d'EMAG. La viscosité cinématique est déterminée en mesurant le temps d'écoulement d'un volume de liquide sous l'effet de la gravité à travers un viscosimètre capillaire en verre calibré. La viscosité dynamique, η, est obtenue en multipliant la viscosité cinématique mesurée par la masse volumique, ρ, du liquide. La plage de viscosités cinématiques couverte dans la présente méthode d’essai est comprise entre 0,2 mm2/s et 300 000 mm2/s sur la plage de températures de –20 °C à +150 °C.
NOTE            Le résultat obtenu avec le présent document dépend du comportement de l’échantillon et est destiné à une application sur des liquides dont les contraintes de cisaillement et les vitesses de cisaillement sont proportionnelles (comportement d’écoulement newtonien). Si, cependant, la viscosité varie significativement avec la vitesse de cisaillement, des résultats différents peuvent être obtenus à partir de viscosimètres ayant des diamètres de capillaire différents. Le mode opératoire et les valeurs de fidélité pour les combustibles résiduels, qui dans certaines conditions présentent un comportement non newtonien, ont été inclus.

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.
