This European Standard specifies a test method for the determination of the electrical conductivity in ethanol and ethanol (E85) automotive fuel in the range from approximately (0,3 to 5) μS/cm at a temperature of 25 °C (see Clause 4). The electrical conductivity is determined from the measured electrical conductance.

The electrical conductivity is an important analytical criterion for the ascertainment and control of anionic and cationic components in ethanol and ethanol (E85) automotive fuel. Some of these components can exhibit corrosive properties.
