Tannas-King Company have officially received the test method number for the Conductive Deposit Test (CDT). It will be known as ASTM D8544, titled "Standard Test Method for Determination of Conductive Deposits on Electrical and Mechanical Components from Fluids in Liquid and Vapor States within an Electrically Charged System."

       The ASTM D8544 standard will be published and made available for download from the ASTM.org website starting March 14. We encourage you to visit the website to access .

      The CDT is designed to determine the tendency of lubricating, fluids to form conductive layer deposits on exposed copper motor windings, connectors, and electrical components at elevated temperatures in an Electrified Vehicle (EV) Drivetrain.

With the rapid increase in EV mobility of all types (EV,BEV, Hybrid, etc…), the need for EV fluids with special performance specifications and characteristics is critical. Failures in EV motors have been shown to relate to growth of the conductive layer deposits that connect the hairpin locations of the motor winding, providing a pathway for current to flow via the deposit. Conductive deposits form from the chemical reaction of the lubricating fluid and copper motor windings and electrical components in very small areas at elevated temperatures. The CDT is developed to protect EV motors and drivetrains by Tannas-King company (from experimental labs around the world).

TanEV CDT with Small, non-liquid benchtop footprint, has (4) independent heating/data units per docking station and works with a QR code to an IOS application for starting/stopping tests and capturing data, and can operate under 150°C for 500 hr. to test liquid & vapor phase conductive deposit formation.
