Standard Test Method for Lubricating Qualities of Graphites (Withdrawn 2006)
SCOPE
1.1 This test method covers evaluation of the abrasive properties of graphites that are used for lubricating purposes.
1.2 The values stated in SI units are to be regarded as the standard. The values stated in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers evaluation of the abrasive properties of graphites that are used for lubricating purposes.
Formerly under the jurisdiction of Committee D02 on Petroleum Products and Lubricants, this test method was withdrawn in October 2006.
This standard is being withdrawn without replacement due to its lack of use in the industry.

3. Summary of Test Method
3.1 A representative sample of the graphite is suspended in
mineral oil, and the mixture containing 15 % by weight of
graphite is circulated through a ball bearing by means of an
impeller and duct assembly.The bearing shaft is driven at 1750
rpm for a period of 2 h. The loss in weight of the bearing is
determined.

8. Procedure
8.1 After the dry bearing has been brought to room tem-
perature in a desiccator, weigh it to the nearest 0.1 mg. Repeat
the cleaning and drying operations as described in Section 7
until a constant weight is obtained.
8.2 Place the bearing in the upper end of the bell, so that the
outer ring is seated firmly. Screw the bell tightly by finger on
the cylindrical duct, thereby locking the bearing outer ring in
place. Place the bushing on the shaft and finger screw the
propeller tightly on the left-hand thread located at the bottom
of the shaft. The bushing serves to lock the inner ring of the
bearing to the shaft. At this point the equipment should be
checked as to freedom from applied loads in accordance with
the procedure outlined in Annex A1.
8.3 Using the 400-mL-Griffin beaker, prepare a mixture of
36 6 0.1 g of the sample graphite and 204 6 0.1 g of the
mineral oil (see 6.2).
8.4 Disperse the graphite in the oil by stirring with a spatula
until scraping of the bottom of the beaker shows no aggregates
of graphite.
8.5 When uniform suspension of the graphite has been
achieved,placethebeakerintheseatprovidedinthebaseplate
of the stand. Then lower the bearing assembly into the beaker
until there is a 6.4-mm (0.25-in.) clearance between the bottom
of the bell section of the duct and the beaker.
8.6 By means of the pipet, draw off a sufficient quantity of
the mixture to lower the level of the liquid to coincide with the

the liquid is at this level, one-half of the area of each port hole
is covered by the mixture.
