ISO 32662-1:2025

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 12mg/kg to 26mg/kg and it was established in an interlaboratory study by applying ISO4259-1[4].

This document in general is applicable to products having a kinematic viscosity not exceeding 8mm²/s at 20°C, or 5mm²/s at 40°C.

This test method can be used for paraffinic diesel fuels as specified in EN15940, for diesel fuels containing a volume fraction of more than 30%FAME and for petroleum products having a kinematic viscosity exceeding 8mm²/s at 20°C, or 5mm²/s at 40°C, however in such cases the precision of the test method has not been determined.
