Scope:

This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles.

This specification defines the requirements used to describe the properties and performance characteristics of chassis greases and wheel bearing greases for service-fill applications.

The test requirements (acceptance limits) given in this specification are, as the case may be, minimum or maximum acceptable values for valid duplicate test results. No additional corrections for test precision, such as described in Practice D 3244, are to be applied inasmuch as the precision of the test methods was taken into account in the determination of the requirements.

The values stated in SI units are to be regarded as the standard. The values given in inch-pound units are for information only.
