ASTM D7528-09 PDF

1.1 This test method describes a bench procedure to simulate the oil aging encountered in Test Method D 7320, 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 D 7320.

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.

1.3 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. Specific warning statements are given in Sections 7 and 8.
