PD CEN/TR 16885 is a technical report, that describes the investigation into the development of a standard test method to determine oxidation stability of diesel fuel and fatty acid methyl ester (FAME) blends in diesel by the use of determining the acid number after ageing at elevated temperature.
PD CEN/TR 16885 provides conclusions following this work that have been discussed by CEN. The result thereof is that no European Standard has been developed.
PD CEN/TR 16885 on the investigation on test method for measurement of the oxidation stability of diesel and diesel/FAME blends is useful for:
In case of poor diesel or biodiesel quality, ageing of the fuel in the fuel system under high pressure and temperature (recirculation of fuel, high injector temperature, long storage in the vehicle fuel tank) may cause various car problems due to the formation of acidity through oxidation (i.e., deposit of sediments, deposit of lacquer, corrosion, lube oil deterioration).
Acidity of the fuel is therefore considered as a relevant parameter to evaluate oxidation stability of the Diesel fuel.
PD CEN/TR 16885 provides you investigation analysis which enables you to assess the oxidation stability of diesel and diesel/FAME blends using test methods based on the measurement of the acid number (AN) after an ageing.
