Petroleum products and related products - Determination of kinematic viscosity - Method by Stabinger type viscometer (ISO 23581:2024)

This document specifies a procedure for the determination of kinematic viscosity, ν, by calculation from dynamic viscosity, η, and density, ρ, of both transparent and opaque liquid petroleum products and crude oils using the Stabinger type viscometer.
The result obtained using the procedure described in this document depends on the rheological behaviour of the sample. This document is predominantly applicable to liquids whose shear stress and shear rate are proportional (Newtonian flow behaviour). If the viscosity changes significantly with the shear rate, comparison with other measuring methods is not possible except at similar shear rates.
The precision has been determined only for the materials, density ranges and temperatures described in Clause 13. The test method can be applied to a wider range of viscosity, density, temperature and materials. It is possible that the precision and bias are applicable for materials which are not listed in Clause 13.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung der dynamischen Viskosität und Berechnung der kinematischen Viskosität - Verfahren mit dem Viskosimeter nach dem Stabinger-Prinzip (ISO 23581:2024)

Dieses Dokument legt ein Verfahren fest, in dem die kinematische Viskosität (ν) von sowohl durchsichtigen als auch undurchsichtigen flüssigen Mineralölerzeugnissen und Mineralölen unter Verwendung eines Viskosimeters nach dem Stabinger-Prinzip bestimmt wird, die kinematische Viskosität wird dabei durch Berechnung aus der dynamischen Viskosität (η) und der Dichte (ρ) ermittelt.
Das unter Anwendung des in diesem Dokument beschriebenen Verfahrens erzielte Ergebnis ist vom Fließverhalten der Probe abhängig. Dieses Dokument ist hauptsächlich auf Flüssigkeiten anwendbar, deren Schubspannung und Schergeschwindigkeit proportional sind (Newtonsches Fließverhalten). Ändert sich die Viskosität signifikant mit der Schergeschwindigkeit, ist der Vergleich mit anderen Messverfahren nicht möglich mit Ausnahme bei ähnlichen Schergeschwindigkeiten.
Die Präzision wurde nur für die in Abschnitt 13 beschriebenen Materialien, Dichtebereiche und Temperaturen bestimmt. Das Prüfverfahren kann auf einen breiteren Bereich von Viskosität, Dichte, Temperatur und Materialien angewendet werden. Es ist möglich, dass die Präzision und die systematische Abweichung auf Materialien anwendbar sind, die nicht in Abschnitt 13 aufgeführt sind.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor der Anwendung dieses Dokuments geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und die Geltung weiterer diesbezüglicher Auflagen zu prüfen.

Produits pétroliers et produits connexes - Détermination de la viscosité cinématique - Méthode par viscosimètre type Stabinger (ISO 23581:2024)

Le présent document spécifie une méthode de détermination de la viscosité cinématique, ν, par calcul à partir de la viscosité dynamique, η, et de la masse volumique, ρ, des produits pétroliers liquides transparents et opaques et des huiles brutes à l'aide du viscosimètre de type Stabinger.
Le résultat obtenu en utilisant la méthode décrite dans le présent document dépend du comportement rhéologique de l'échantillon. Ce document s'applique principalement à des liquides dont la contrainte de cisaillement et le taux de cisaillement sont proportionnels (comportement d'écoulement newtonien). Cependant, si la viscosité varie de manière significative avec le taux de cisaillement, une comparaison avec d'autres méthodes de mesure n'est pertinente qu'à des taux de cisaillement similaires.
La fidélité a été déterminée pour les produits, les gammes de masse volumique et de température décrites à l'Article 13. La méthode d'essai peut être appliquée à une gamme plus large de viscosité, de masse volumique,  de température et de produits. Il est possible que la fidélité et le biais puissent être applicables à des produits qui ne figurent pas à l’Article 13.
