Abstract: A method for testing a heat transfer fluid based on a charged wire test (CWT) includes applying and measuring discharge current through a test circuit formed when a cathode and an anode are at least partially immersed in the heat transfer fluid in a container and a voltmeter coupled to the cathode and the anode is turned on during the CWT. The method includes measuring temperature of the heat transfer fluid during the CWT, determining a current profile based on the measured discharge current, and determining a temperature profile based on the measured temperature. The method includes determining a pass/fail status and/or a rank status of the heat transfer fluid based on pass/fail criteria based on the current profile and the temperature profile during an entire duration of the CWT.

Abstract: Heat transfer fluids were formulated with a neat solution of a synthetic ester base stock. A base stock prepared with a neat ester according to the invention has similar performance characteristics to commercially available heat transfer fluids.
