Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids - TOST test - Part 1 : procedure for mineral oils

<p>ISO 4263-1:2003 specifies a method for the determination of the ageing behaviour of rust- and oxidation- inhibited mineral oils having a density less than that of water, used as turbine oils (categories TSA, TGA, TSE, TGE of ISO 6743-5, hydraulic oils (categories HL, HM, HR, HV, HG of ISO 6743-4), and circulating oils (category CKB of ISO 6743-6). Oils containing synthetic components can be tested by this procedure, but no precision statement is available yet for such fluids.</p> <p>This test method is widely used in specifications and is considered of value in comparing the oxidation stability of oils that are 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.</p>

Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids - TOST test - Part 2 : procedure for category HFC hydraulic fluids

<p>ISO 4263-2:2003 specifies a method for the determination of the ageing behaviour of hydraulic fluids of category HFC as defined in ISO 6743-4 and specified in ISO 12922. The ageing is accelerated by the presence of oxygen, water and metal catalysts at elevated temperature, and the degradation of the fluid is followed by changes in pH value and insolubles content. Other parts of ISO 4263 specify similar procedures for the determination of the ageing behaviour of mineral oils and specified categories of fire-resistant fluids used in hydraulic and other applications.</p>

Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids - TOST test - Part 3 : anhydrous procedure for synthetic hydraulic fluids

Le présent document prescrit une méthode permettant d'évaluer les caractéristiques de vieillissement des fluides hydrauliques de catégorie HFDR, HFDU, HEES et HEPG. Dans cette méthode, le vieillissement est accéléré par la présence d'oxygène et de catalyseurs métalliques à température élevée. La dégradation du fluide est suivie par l'évolution de son indice d'acide.
