• Phạm vi áp dụng / Scope of standard: 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. 1.4 This test method is arranged as follows:SectionScope1Reference Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus6Reagents and Materials7Hazards8Reference Oil Testing and Test Stand Calibration9Procedure10Cleaning11Calculations and Determination of Test Results12Report13Precision and Bias14Keywords15AnnexesReaction VesselAnnex A1Reaction Vessel HeadAnnex A2Reaction Vessel-to-Head SealAnnex A3Agitator Turbine BladeAnnex A4Agitator Packing GlandAnnex A5Nitrogen Dioxide Graduated TubeAnnex A6Vacuum System PlumbingAnnex A7Vacuum Trap CondensersAnnex A8Setting the Vacuum Control ValveAnnex A9AppendixesSample Preparation and AdditionAppendix X1Charging the Liquid Nitrogen DioxideAppendix X2Nitrogen Dioxide Precision Needle ValveAppendix X3Example of an Assembled ROBO ApparatusAppendix X4Information Package to Aid Setting Up a New Robo ApparatusAppendix X5
