Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids using the TOST test - Part 3: Anhydrous procedure for synthetic hydraulic fluids (ISO 4263-3:2015)
ISO 4263-3:2015 specifies a method for the determination of the ageing behaviour of synthetic hydraulic fluids of categories HFDU, HEES, HEPG and HETG as defined, for example, in ISO 12922[1] and ISO 15380[2]. The ageing is accelerated by the presence of oxygen and metal catalysts at elevated temperature, and the degradation of the fluid is followed by changes in acid number. Other parts of ISO 4263 specify similar procedures for the determination of ageing behaviour of mineral oils and specified categories of fire-resistant fluids used in hydraulic and other applications.
NOTE Other signs of fluid deterioration, such as the formation of insoluble sludge, catalyst coil corrosion or change in viscosity, can occur which indicate oxidation of the fluid, but are not reflected in the calculated oxidation lifetime. The correlation of these occurrences with field service is under investigation. This test method may be used to compare the oxidation stability of fluids that are not prone to contamination with water. However, because of the large number of individual field-service applications, the correlation between the results of this test and actual service performance can vary markedly, and is best judged on experience. The precision of this test method for synthetic hydraulic fluids is not known because interlaboratory data are not available. This method might not be suitable for use in specifications or in the event of disputed results as long as these data are not available.
Mineralölerzeugnisse und verwandte Produkte - Bestimmung des Alterungsverhaltens von inhibierten Ölen und Flüssigkeiten unter Anwendung des TOST-Verfahrens - Teil 3: Wasserfreies Verfahren für synthetische Druckflüssigkeiten (ISO 4263-3:2015)
Dieser Teil von ISO 4263 legt ein Verfahren zur Bestimmung des Alterungsverhaltens von synthetischen Druckflüssigkeiten der Klassen HFDU, HEES, HEPG und HETG, die z. B. in ISO 12922 [1] und ISO 15380 [2] definiert sind, fest. Die Alterung wird beschleunigt durch die Anwesenheit von Sauerstoff und Metall-Katalysatoren bei erhöhten Temperaturen, und die Alterung der Flüssigkeit wird über die Änderung der Säurezahl verfolgt. Andere Teile von ISO 4263 legen ähnliche Verfahren für die Bestimmung des Alterungsverhaltens von Mineralöl und spezifizierten Klassen von schwerentflammbaren Flüssigkeiten fest, die in hydraulischen und anderen Anwendungen eingesetzt werden.
ANMERKUNG Andere Zerfallserscheinungen, wie die Bildung von unlöslichem Schlamm, die Korrosion der Katalysatorwendeln oder die Veränderung der Viskosität können auftreten und sind ein Anzeichen für Oxidationsvorgänge in der Flüssigkeit, die jedoch nicht in die Berechnungen der Oxidationslebensdauer aufgenommen wurden. Die Korrelation dieser Vorkommnisse mit Anwendungen in der Praxis wird noch untersucht. Dieses Prüfverfahren darf zum Vergleich der Oxidationsstabilität von Flüssigkeiten herangezogen werden, für die eine Verunreinigung mit Wasser nicht wahrscheinlich ist. Wegen der großen Anzahl individueller Anwendungen in der Praxis kann jedoch die Übereinstimmung der Ergebnisse dieser Prüfung von der tatsächlichen Leistungsfähigkeit deutlich abweichen und erst im Betriebseinsatz beurteilt werden. Die Präzision für dieses Prüfverfahren für Druckflüssigkeiten ist wegen fehlender Ringversuchsergebnisse nicht bekannt. Dieses Verfahren ist für den Einsatz in Spezifikationen oder im Streitfall nicht geeignet, solange entsprechende Daten nicht verfügbar sind.
Pétrole et produits connexes - Détermination du comportement au vieillissement des fluides et huiles inhibés au moyen de l'essai TOST - Partie 3: Méthode anhydre pour les fluides hydrauliques synthétiques (ISO 4263-3:2015)
L'ISO 4263-3 :2015 spécifie une méthode permettant d'évaluer les caractéristiques de vieillissement des fluides hydrauliques synthétiques des catégories HFDU, HEES, HEPG et HETG définies par exemple dans l'ISO 12922[1] et l'ISO 15380[2]. Le vieillissement est accéléré par la présence d'oxygène et de catalyseurs métalliques à température élevée et la dégradation du fluide est suivie par l'évolution de son indice d'acide. D'autres parties de l'ISO 4263 spécifient 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.
NOTE D'autres signes peuvent indiquer la détérioration des fluides, comme la formation de dépôts insolubles, la corrosion du bobinage de catalyseurs, ou un changement de viscosité. Cela traduit une oxydation du fluide mais il n'en est pas tenu compte pour la prévision de la durée de résistance à l'oxydation. Une étude est en cours pour essayer d'établir une corrélation entre ces phénomènes et l'utilisation en service. La présente méthode d'essai peut servir à comparer la stabilité à l'oxydation de fluides qui ne sont pas sujets à la contamination par l'eau. Cependant, en raison du très grand nombre de types d'applications sur le terrain, la corrélation des résultats de ces essais avec les performances réelles en service peut varier beaucoup, et il est préférable de faire appel à l'expérience. La fidélité de la présente méthode d'essai n'est pas établie car aucun essai interlaboratoires n'a été effectué. Tant que de tels essais n'ont pas été faits, il se peut que la méthode soit jugée inacceptable pour le contrôle des spécifications ou en cas de litige.
Nafta in sorodni proizvodi - Določevanje staranja inhibiranih olj in tekočin s preskusom TOST - 3. del: Brezvodni postopek za sintetične hidravlične tekočine (ISO 4263-3:2015)
Ta del standarda ISO 4263 določa metodo določevanja staranja sintetičnih hidravličnih tekočin kategorij HFDU, HEES, HEPG in HETG, kot so na primer opredeljene v standardih ISO 12922[1] in ISO 15380[2]. Staranje pospešuje prisotnost kisika in kovinskih katalizatorjev pri povišani temperaturi, pri čemer degradaciji tekočine sledijo spremembe v kislinskem številu. Drugi deli standarda ISO 4263 določajo podobne postopke za določevanje staranja mineralnih olj in navedenih kategorij negorljivih tekočin, ki se uporabljajo v hidravličnih ali drugih sistemih.
OPOMBA Pojavijo se lahko tudi drugi znaki kvarjenja tekočine, ki označujejo oksidacijo tekočine, kot je nastanek netopnega blata, korozija tuljave v katalizatorju ali sprememba viskoznosti, vendar ti niso vključeni v izračunano življenjsko dobo oksidacije. Trenutno poteka raziskava povezave teh pojavitev s storitvami na terenu. Ta preskusna metoda se lahko uporabi za primerjavo oksidacijske stabilnosti tekočin, ki niso nagnjene k onesnaženju z vodo. Vendar je lahko zaradi velikega števila posameznih uporab na terenu povezava med rezultati tega preskusa in dejanskim delovanjem storitve zelo različna, pri čemer jo je priporočljivo presoditi na podlagi izkušenj. Natančnost te preskusne metode za sintetične hidravlične tekočine ni znana, saj medlaboratorijski podatki niso na voljo. Ta metoda v primeru, da ti podatki niso na voljo, morda ni primerna za uporabo v specifikacijah ali v primeru sporov pri razlagi rezultatov.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
