This European Standard specifies a method for determining contamination as the content of undissolved
substances in middle distillates containing up to 5 % (V/V) fatty acid methyl esters (FAME) and in 100 % (V/V)
FAME. This method can be applied for contaminant content from 6 mg/kg to 30 mg/kg.
NOTE 1 Excessive contamination in a fuel system can give rise to premature blocking of filters and / or hardware failure, and is therefore undesirable.
This standard applies to liquid petroleum 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] or light fuel oils.
Although the test method precision has not been defined, the method described may also be used for blends
containing more than 5% (V/V) FAME and for petroleum products having a viscosity exceeding the above.
NOTE 2 For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction.
