This document 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). The working range is from 12 mg\/kg to 26 mg\/kg and it was established in an interlaboratory study by applying EN ISO 4259-1 [4]. This document in general is applicable to products having a kinematic viscosity not exceeding 8 mm2\/s at 20 \u00b0C, or 5 mm2\/s at 40 \u00b0C. This test method can be used for paraffinic diesel fuels as specified in EN 15940, for diesel fuels containing more than 30 % (V\/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2\/s at 20 \u00b0C, or 5 mm2\/s at 40 \u00b0C, however in such cases the precision of the test method has not been determined. NOTE For the purposes of this document, the term \u201c% (V\/V)\u201d is used to represent the volume fraction, \u03c6, of a material.
