About This Item


Full Description

ISO 6246:2017 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 heptane-insoluble portion of the residue is also described.
