2Scope / Description
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, for example, in ISO 12922 and ISO 15380. The ageing is accelerated by the presence of oxygen and metal catalysts at elevated temperaturem 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.
