Standard Classification and Specification of Automotive Service Greases
SCOPE
1.1 This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles.
1.2 This specification defines the requirements used to describe the properties and performance characteristics of chassis greases and wheel bearing greases for service-fill applications.
1.3 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.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4.1 Exception—Test Method D 2596 reports test results in kgf units. Until that standard is revised, Classification and Specification D 4950 will show kgf units in parentheses after the SI units for information only.

INTRODUCTION
This specification describes current categories of lubricating greases for automotive service-fill
applications. A specific designation is assigned to each category. The system is open ended, that is,
new designations are assigned for use with new categories as each new set of grease performance
characteristics is defined. Grease categories are referenced by automotive manufacturers in making
lubrication recommendations and used by grease suppliers and users in identifying products for
specific applications.
