Scope

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. 1.3 This test method is arranged as follows: Section Scope 1 Reference Documents 2 Terminology 3 Summary of Test Method 4 Significance and Use 5 Apparatus 6 Reagents and Materials 7 Hazards 8 New and Existing Test Stand Calibration 9 Procedure 10 Cleaning 11 Calculations and Determination of Test Results 12 Report 13 Precision and Bias 14 Keywords 15 Annexes ASTM Test Monitoring Center: Organization Annex A1 ASTM Test Monitoring Center: Calibration Procedures Annex A2 ASTM Test Monitoring Center: Maintenance Activities Annex A3 ASTM Test Monitoring Center: Related Information Annex A4 Reaction Vessel Annex A5 Reaction Vessel Head Annex A6 Reaction Vessel-to-Head Seal Annex A7 Agitator Turbine Blade Annex A8 Agitator Packing Gland Annex A9 Nitrogen Dioxide Graduated Tube Annex A10 Vacuum System Plumbing Annex A11 Vacuum Trap Condensers Annex A12 Setting the Vacuum Control Valve Annex A13 Appendixes 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of Subcommittee D02.B0.07 on Development and Surveillance of Bench Tests Methods. Current edition approved Oct. 1, 2017. Published October 2017. Originally approved in 2009. Last previous edition approved in 2017 as D7528 – 17.
