Liquid petroleum products — Determination of total contamination — Part 1: Middle distillates and diesel fuels

Apstrakt

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 a volume fraction of up to 30 % 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 ISO 4259-1[4].
This document in general is applicable to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C.
This test method can be used for paraffinic diesel fuels as specified in EN 15940, for diesel fuels containing a volume fraction of more than 30 % 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 has not been determined.
