DIN EN 12662-1:2024

Liquid petroleum products - Determination of total contamination - Part 1: Middle distillates and diesel fuels; German version EN 12662-1:2024

This European Standard specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty acid methyl esters (FAME), and in neat FAME. The working range is from 12 mg/kg to 30 mg/kg and it was established in an interlaboratory study by applying EN ISO 4259. This European Standard in general applies to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e. g. diesel fuel as specified in EN 590[1]. This test method may be used for diesel fuels containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, however in such cases the precision of the test method is not defined.
