New Test Method for determining the rate of copper corrosion in electric vehicle transmission fluids

1. Scope

Establish a new test method, including coordination of ILS testing required to determine test precision.


copper; corrosion; electric vehicle; transmission; wire; oxidation; resistance measurement


The increased use of copper in electric vehicle applications such as motor windings and interconnects has raised the importance of corrosion resistance for fluids that potentially can contact such copper substrates. This proposed test quantitatively measures the rate of corrosion in copper exposed to test fluids at various temperatures. Both liquid and vapor exposure is included in this test method.

The title and scope are in draft form and are under development within this ASTM Committee.
