ISO 17308:2015

Petroleum products and other liquids — Ethanol — Determination of electrical conductivity

ISO 17308:2015 specifies a test method for the determination of the electrical conductivity in ethanol fuel and mixtures (including E85) in the range of 0,5 μS·cm−1 to 4 μS·cm−1 at a temperature of 25 °C. The electrical conductivity is determined from the measured electrical conductance.
