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 -20°C (0°F)).

1.1.1 Torque measurements are limited by the capacity of the torque-measuring equipment.

Note 1-When initially developed, the original dynamometer scale limited the torque capacity to approximately 30000 g[dot]cm; the original dynamometer scale is obsolete, however. The suggested replacement scale has not been evaluated; it could extend the limit to approximately 75000 g[dot]cm.

1.2 The values stated in SI units are to be regarded as the standard in this test method, except for torque values which are given in cgs-metric units, which are universally used in grease specifications. Other units are provided for information only.

1.3 This standard does not purport to address all of the safety problems, 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 Notes 2, 4, 5, 6, and 8.
