适用范围：This standard applies to used petrol and diesel engine oils．Whether it can be applied to other oils is currentlybeing checked．The methOd described serves to determine the extent of oxidation and nitration in used engine and gear oilsbv measuring the absorption of infrared light of certain wavelengths using fresh oil of the same type as a IIre。ference．The values obtained are a measure of the ageing of the oil． 1 Evaluation of the oxidation is made difficult or impossible—if the oil contains more than 3％soot；——if it contai ns ester-based add itives or if the oi l itself is ester—based；一if it is used with biodiesel(i．e．FAME(fatty acid methyl ester))；The arOmatic band at 1 600 cm
