Electrical Conductivity

  • Method ASTM D2624
  • Repeatability variable, see method
  • Reproducibility variable, see method
  • Blending non-linear
  • Additive Correction Yes

The purpose of this test is to measure the amount of electrical conductivity in distillates and aviation fuels without a static dissipater additive when the product is said to be uncharged or electrically at rest.

When a transferring fuels through pumps or filters they can accumulate electrical charges, which can be dangerous if not dissipated. The electrical conductivity is a measure of how conductive the fuel is or how quickly the electrical charge is allow to dissipate. The higher the conductivity the faster the charge will dissipate.

The method is run by placing sample inside a metal cup and taking a reading using a conductivity meter. This meter converts the resistance of the product between the two electrodes to a conductivity value.
