Introduction
Excessive contamination in a fuel system can give rise to premature blocking of filters and/or hardware
failure, and is therefore undesirable. The determination of the content of undissolved substances,
referred to as total contamination, is a way to control this issue.
In the previous version of this method, the scope was covering middle distillates, diesel fuels containing
up to 30 % (V/V) of FAME and neat FAME. It was found that the improvement sought in 2014, give
problems in the lab in testing FAME and correlate the results to those obtained with the previous version
of the method. A solution has been found, which resulted in splitting the methodology in two parts: to
include the previous version as Part 1 and to develop a separate standard for neat FAME as Part 2.
1 Scope
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 mm /s
at 20 °C, or 5 mm /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
2 2
exceeding 8 mm /s at 20 °C, or 5 mm /s at 40 °C, however in such cases the precision of the test method
has not been determined.
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction, φ, of a

L'étendue de la norme couvre des cas pratiques pour des produits ayant une viscosité cinématique n'excédant pas 8 mm²/s à 20 °C, ou 5 mm²/s à 40 °C. Cela en fait un outil essentiel pour les analyses relatives à la qualité des carburants, garantissant que les combustibles diesel répondent aux normes de propreté et de performance. De plus, la méthode peut être utilisée pour caractériser les carburants diesel paraphiniques conformément à la norme EN 15940, renforçant ainsi sa pertinence dans des applications industrielles variées. Les points forts de la norme incluent son application à un large éventail de carburants et ses fondements scientifiquement validés par une étude interlaboratoire selon la méthode EN ISO 4259-1. Cela assure non seulement la fiabilité des résultats obtenus, mais également leur précision dans un cadre de travail défini. En outre, la norme propose une approche systématique pour les utilisateurs, tout en les avertissant des risques liés à la manipulation de matériaux potentiellement dangereux. La norme SIST EN 12662-1:2024 est donc non seulement un guide fondamental pour la détermination de la contamination totale dans les carburants diesel, mais aussi un instrument crucial pour assurer la conformité aux réglementations dans le secteur des produits pétroliers. Sa pertinence et sa robustesse en font un document incontournable pour les professionnels impliqués dans le contrôle de la qualité des carburants.
