Abstract
Lubricity of a sample of lubricant may be determined by precisely measuring temperature from friction generated between two or more moving parts in contact under force. For example, to carry this out, a rotatable pin and vee block test apparatus set forth in ASTM D2760-95 (Reapproved 2010) can be provided, and modified to provide its rotating pin with a hole longitudinally along an axis of the pin about which the pin rotates during testing. The hole is configured to receive, and for the testing receives, a thermocouple to measure temperature during the testing.
