EN 14112:2003 (E)3IntroductionThis European Standard is based on the ISO 6886 [1], which was specifically adapted for the determination ofoxidation stability of fatty acid methyl esters (FAME).SIST EN 14112:2003
EN 14112:2003 (E)41 ScopeThis European Standard specifies a method for the determination of the oxidation stability of fatty acid methylesters (FAME) at 110 °C.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1induction periodtime which passes between the moment when the measurement is started and the moment when the formation ofoxidation products rapidly begins to increase2.2oxidation stabilityinduction period determined according to the procedure specified in this European Standard. Oxidation stability isexpressed in hours3 PrincipleA stream of purified air is passed through the sample which has been brought to a specified temperature. Thevapours released during the oxidation process, together with the air, are passed into a flask containing water whichhas been demineralized or distilled and contains an electrode for measuring the conductivity. The electrode isconnected to a measuring and recording device. It indicates the end of the induction period when the conductivitybegins to increase rapidly. This accelerated increase is caused by the dissociation of vola
