1.1''This test method describes a bench procedure to simulate the oil aging encountered in Test Method D7320, the Sequence IIIG engine test method. These aged oils are then tested for kinematic viscosity and for low-temperature pumpability properties as described in the Sequence IIIGA engine test, Appendix X1 of Test Method D7320.

1.2''Units'''The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1''Exceptions'''There are no SI equivalents for some apparatus in Section 6, and there are some figures where inch units are to be regarded as standard.
