ASTM D1478 Low Temperature Torque of Ball Bearing Grease

The torque resulting from grease lubricated ball bearings rotated at one rpm is measured.  The test is designed for temperatures 0°F (-20°C) and below.  Torques greater than 35,000 g-cm (3.5 N-m) are considered to be technically frozen.  Most military grease specifications consider 10,000 g-cm (1 N-m) to be the maximum usable limit for adequate lubrication at low temperatures.  Test temperatures to -73°C can be accommodated.
