ASTM D2983

Low-Temperature Viscosity of Automatic Transmission Fluids, Hydraulic Fluids, and Lubricants using a Rotational Viscometer

Applicability: ASTM D2983 is a standard test method for determining the low-temperature, low-shear-rate viscosity of fluids and lubricants using a rotational viscometer. It is primarily used for automatic transmission fluids, gear oils, torque and tractor fluids, industrial and automotive hydraulic oils, and some other lubricants.

Purpose: The test method helps assess how these fluids perform at low temperatures, which is crucial for their proper functioning in various applications.
