EN ISO 4263-2:2003

Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids - TOST test - Part 2: Procedure for category HFC hydraulic fluids (ISO 4263-2:2003)

ISO 4263-2:2003 specifies a method for the determination of the ageing behaviour of hydraulic fluids of category HFC as defined in ISO 6743-4 and specified in ISO 12922. The ageing is accelerated by the presence of oxygen, water and metal catalysts at elevated temperature, and the degradation of the fluid is followed by changes in pH value and insolubles content. Other parts of ISO 4263 specify similar procedures for the determination of the ageing behaviour of mineral oils and specified categories of fire-resistant fluids used in hydraulic and other applications.

Mineralölerzeugnisse und verwandte Produkte - Bestimmung des Alterungsverhaltens von inhibierten Ölen und Flüssigkeiten - TOST Test - Teil 2: Verfahren für Druckflüssigkeiten der Klasse HFC (ISO 4263-2:2003)

Dieser Teil von ISO 4263 legt ein Verfahren fest zur Bestimmung des Alterungsverhaltens von Druckflüssigkeiten der Klasse HFC, wie sie in ISO 6743-4 (siehe [2] der Literaturhinweise) definiert und in ISO 12922 (siehe [3] der Literaturhinweise) festgelegt sind. Die Alterung wird beschleunigt durch die Anwesenheit von Sauerstoff, Wasser und Metall-Katalysatoren bei erhöhten Temperaturen, und die Zerfallserscheinungen in der Flüssigkeit werden über die Änderung des pH-Wertes und durch den Gehalt an Unlöslichem verfolgt. Andere Teile von ISO 4263 legen ähnliche Verfahren für die Bestimmung des Alterungsverhaltens von Mineralölen und spezifizierten Klassen von schwerentflammbaren Flüssigkeiten fest, die in hydraulischen und anderen Anwendungen eingesetzt werden.
ANMERKUNG   Für die Anwendung dieses Teiles von ISO 4263 wird die Bezeichnung "% (m/m)" für Massenanteil in Prozent eines Materials verwendet.

Pétrole et produits et produits connexes - Détermination du comportement au vieillissement des fluides et huiles inhibées - Essai TOST - Partie 2: Méthode pour les fluides hydrauliques de catégorie HFC (ISO 4263-2:2003)

L'ISO 4263-2:2003 spécifie une méthode permettant d'évaluer le comportement au vieillissement des fluides hydrauliques de catégorie HFC, tels qu'ils sont définis dans l'ISO 6743-4 et spécifiés dans l'ISO 12922. Dans cette méthode, le vieillissement est accéléré par la présence d'oxygène, d'eau et de catalyseurs métalliques à température élevée. La dégradation du fluide est suivie par l'évolution de la valeur du pH et de la teneur en produits insolubles. D'autres parties de l'ISO 4263 décrivent des méthodes similaires permettant d'évaluer les caractéristiques de vieillissement des huiles minérales et de catégories spécifiques de fluides difficilement inflammables utilisés dans des applications hydrauliques et autres.
