Historical Standard: Standard Test Method for Low-Temperature Torque of Ball Bearing Grease
ASTM D1478
Scope
1.1 This test method covers the determination of the extent to which a grease retards the rotation of a slow-speed ball bearing by measuring starting and running torques at low temperatures (below ā20Ā°C (0Ā°F)).
1.1.1 Torque measurements are limited by the capacity of the torque-measuring equipment.
Note 1āWhen initially developed, the original dynamometer scale limited the torque capacity to approximately 30 000 gĀ·cm; the original dynamometer scale is obsolete, however. The suggested replacement scale has not been evaluated; it could extend the limit to approximately 75 000 gĀ·cm.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. The exception is torque values that are given in cgs-metric units, which are universally used in grease specifications.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard and warning statements, see 6.1.1, 7.2, 7.4, 8.7, and 8.11.
