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.

This part of ISO 4263 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] temperature, and the degradation of the fluid is followed by changes in acid number. Other parts of 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.

This part of ISO 4404 specifies a procedure for the determination of the corrosion-inhibiting properties of non-aqueous hydraulic fluids within the category HFD, as classified in ISO 6743-4. It provides a qualitative assessment of corrosion of five of the most common metals used in the construction of hydraulic systems, but other metals and/or alloys could be added or substituted for these metals for particular installations. NOTE The determination of corrosion resistance of aqueous hydraulic fluids within categories HFA, HFB and HFC is described in ISO 4404-1.

1.1 This specification covers mineral oils used in hydraulic systems, where the performance requirements demand fluids with one of the following characteristics: 1.1.1 A refined base oil (Class HH), 1.1.2 A refined mineral base oil with rust and oxidation inhibitors (Class HL), and 1.1.3 A refined mineral base oil with rust and oxidation inhibitors plus antiwear characteristics (Class HM). 1.2 This specification defines the requirements of mineral oil-based hydraulic fluids that are compatible with most existing machinery components when there is adequate maintenance. 1.3 This specification defines only new lubricating oils before they are installed in the hydraulic system. 1.4 This specification defines specific types of hydraulic oils. It does not include all hydraulic oils. Some oils that are not included may be satisfactory for certain hydraulic applications. Certain equipment or conditions of use may permit or require a wider or narrower range of characteristics than those described herein. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5.1 Exception—In X1.3.9 on Wear Protection, the values of pump pressure are in MPa, and the psi follows in brackets as a reference point immediately recognized by a large part of the industry. 1.6 The following safety hazard caveat pertains to the test methods referenced in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitation prior to use.
