ROTARY BOMB OXIDATION
TEST
ASTM D-2272
1. Scope
1.1 This test method utilizes an oxygen-pressured bomb
to evaluate the oxidation stability of new and in service turbine
oils having the same composition (base stock and additives) in the
presence of water and a copper catalyst coil at 150癈.
3. Summary of Method
3.1 The test oil, water and a copper catalyst coil, contained
in a covered glass container, are placed in a bomb equipped with
pressure gage. The bomb is charged with oxygen to a pressure of
620 kpa (90 psi, 6.2 bar), placed in a constant-temperature bath
set at 150癈, and rotated axially at 100 rpm at an angle of 30癈
from the horizontal. The number of minutes required to reach a specific
drop in gage pressure is the oxidation stability of the test sample.
4. Significance and Use
4.1 The estimate of oxidation stability is useful in controlling
the continuity of this property for batch acceptance of production
lots having the same composition. It is not intended that this test
method be a substitute for test method D 943 or to be used to compare
the service lives of new oils of different compositions.
4.2 This test method is also used to assess the remaining oxidation
test life of in-service oils.
