scope:

1.1 This test method covers the determination of the tendency of a lubricating grease to separate oil during storage in both normally filled and partially filled containers.

1.2 This test method is not suitable for greases softer than NLGI No. 1 grade.

FIG. 1 Pressure Bleeding Test Cell A

1.3 The values stated in SI units are to be regarded as standard, except for the dimensions in Fig. 2 and Fig. 5, where inch-pound units are standard.

FIG. 2 Detailed Drawing of Pressure Bleeding Test Cell A

Note 1: All dimensions are in millimeters (inches).

Note 2: Tolerances are ±0.51 mm (0.02 in.) for 2 place decimals, unless otherwise specified.

Note 3: Tolerances are ±0.127 mm (0.005 in.) for 3 place decimals, unless otherwise specified.

FIG. 4 Pressure Bleeding Test Cell C

FIG. 5 Detailed Drawing of Pressure Bleeding Test Cell C-Strainer Assembly

Note 1: All dimensions are in millimeters (inches).

Note 2: Tolerances are ±0.51 mm (0.02 in.) for 2 place decimals, unless otherwise specified.

Note 3: Tolerances are ±0.127 mm (0.005 in.) for 3 place decimals, unless otherwise specified.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 7.1.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
