Active Standard ASTM D6184 | Developed by Subcommittee: D02.G0.03

Historical (view previous versions of standard)
Significance and Use
When a lubricating grease separates oil, the residual material changes in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are intended to correlate with oil separation that occurs in 35-lb pails of grease during storage. They are not intended to predict oil separation tendencies of grease under dynamic service conditions.
Note 1—No quantitative relationship between results and oil separation in 35-lb pails has been developed.
This test method is used for specifications and quality control.
Note 2—No data have been developed to compare results between this test method and Test Method D 1742
1.1 This test method covers the determination of the tendency of lubricating grease to separate oil at an elevated temperature. This test method shall be conducted at 100°C for 30 h unless other conditions are required by the grease specification.
1.2 This test method is not suitable for greases having a penetration (Test Methods D 217) greater than 340 (softer than NLGI No. 1 grade).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use.
