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 4263-3:2010)
ISO 4263-3:2010 specifies a method for the determination of the ageing behaviour of synthetic hydraulic fluids of categories HFDR, HFDU, HEES and HEPG as defined e.g. in ISO 12922 and ISO 15380. 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.
Other signs of fluid deterioration, such as the formation of insoluble sludge, catalyst coil corrosion or decrease 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.
ISO 4263-3:2010 can 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 ISO 4263-3:2010 and actual service performance can vary markedly, and is best judged on experience.
The precision of ISO 4263-3:2010 for synthetic hydraulic fluids is not known because interlaboratory data are not available. ISO 4263-3:2010 might not be suitable for use in specifications or in the event of disputed results as long as these data are not available. However, precision for inhibited turbine oils is given for guidance as an indication of the precision that could be obtained for synthetic hydraulic fluids.

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 4263-3:2010)
L'ISO 4263-3:2010 spécifie une méthode permettant d'évaluer le comportement au vieillissement des fluides hydrauliques synthétiques des catégories HFDR, HFDU, HEES et HEPG définies par exemple dans l'ISO 12922 et l'ISO 15380. 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 le comportement au vieillissement des huiles minérales et de catégories spécifiques de fluides difficilement inflammables utilisés dans des applications hydrauliques et autres.
D'autres signes peuvent indiquer la détérioration des fluides, comme la formation de dépôts insolubles, la corrosion de la bobine de catalyseur, ou une perte 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 beaucoup varier, et il est préférable de faire appel à l'expérience.
La fidélité de la présente méthode d'essai pour fluides hydrauliques synthétiques n'est pas établie, car aucune donnée provenant d'essais interlaboratoires n'est disponible. Tant que de tels essais n'auront pas été effectués, il se peut que la méthode soit jugée inacceptable pour le contrôle des spécifications ou en cas de litige. Cependant, une fidélité pour les huiles turbines inhibées est donnée, afin de servir d'indication sur ce qui pourrait exister pour les fluides hydrauliques synthétiques.
Nafta in sorodni proizvodi - Določevanje staranja inhibiranih olj in tekočin s preskusom TOST - 3. del: Brezvodni postopek za sintetične hidravlične tekočine (ISO 4263-3:2010)
Ta del ISO 4263 določa metodo za določevanje staranja sintetičnih hidravličnih tekočin kategorij HFDR, HFDU, HEES in HEPG, kot so definirane, na primer, v ISO 12922 in ISO 15380. Staranje se pospeši s prisotnostjo kisika in kovinskih katalizatorjev pri povišani temperaturi in razpadu tekočine sledijo spremembe v kislem številu. Drugi deli ISO 4263 določajo podobne postopke za določevanje staranja mineralnih olj in opredeljenih kategorij ognjevarnih tekočin, ki se uporabljajo v hidravličnih in drugih napravah. To preskusno metodo je mogoče uporabljati za primerjavo oksidacijske stabilnosti tekočin, ki niso nagnjene h kontaminaciji z vodo. Vendar pa se zaradi velikega števila posameznih področij uporab na terenu korelacija med rezultati tega testa in dejansko učinkovitostjo lahko znatno razlikuje in jo je najbolje presoditi na osnovi izkušenj. Natančnost te preskusne metode za sintetične hidravlične tekočine ni znana, ker medlaboratorijski podatki niso na voljo. Ta metoda morda ne bo primerna za uporabo v specifikacijah ali v primeru spornih rezultatov, vse dokler takšni podatki ne bodo na voljo. Vendar pa je natančnost za inhibirana olja za turbine podana v Klavzuli 11 kot vodilo, kot indikacija natančnosti, ki bi jo lahko dosegli za sintetične hidravlične tekočine.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 4263-3 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.

1 Scope
This part of ISO 4263 specifies a method for the determination of the ageing behaviour of synthetic hydraulic
[4]
fluids of categories HFDR, HFDU, HEES and HEPG as defined, for example, in ISO 12922 and
[5]
ISO 15380 . 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 decrease
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 can be used to compare the oxidation stability of fluids that are not prone to contamination
