This document describes the studies executed to develop a method to analyse the filter blocking tendency after a cold soak step of fatty acid methyl ester (FAME) as a blend component for diesel and of diesel fuel containing up to 30 % (V/V) of fatty acid methyl esters (FAME), respectively.

This document establishes the rating of diesel fuel oil in terms of an arbitrary scale of cetane numbers
(CNs) using a standard single cylinder, four-stroke cycle, variable compression ratio, indirect injected
diesel engine. The CN provides a measure of the ignition characteristics of diesel fuel oil in compression
ignition engines. The CN is determined at constant speed in a pre-combustion chamber-type
compression ignition test engine. However, the relationship of test engine performance to...view more

This document specifies a method for determining the existent gum content of aviation fuels and the
gum content of motor gasoline or other volatile distillates. It includes the determination of products
containing ethanol (up to a volume fraction of 85 %) and ether-type oxygenates and deposit control
additives.
For determination of gum content in automotive ethanol (E85) fuel, no precision data is available
(see 14.1).
For non-aviation fuels, a procedure for the determination of the heptan...view more
