DIN EN 12662-1:2024-08

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. 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 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 has not been determined. The responsible national standardization committee is Working Committee NA 062-06-84 AA "Gemeinschaftsausschuss NA 062-06-42 AA/NA 062-06-61 AA" ("Joint working group NA 062-06-42 AA/NA 062-06-61 AA") at DIN Standards Committee Materials Testing (NMP).
