标准简介：This part of ISO 4263 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[4] and ISO 15380[5]. 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
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. However, precision for inhibited turbine oils is given in Clause 11 for
guidance as an indication of the precision that could be obtained for synthetic hydraulic fluids.
