• Phạm vi áp dụng / Scope of standard: 1.1 This test method, commonly referred to as the Cummins ISB Test, covers the utilization of a modern, 5.9-L, diesel engine equipped with exhaust gas recirculation and is used to evaluate oil performance with regard to valve-train wear. 1.2 The values stated in either SI units, inch-pound units, or other units are to be regarded separately as the primary units. 1.2.1 For each parameter, the primary units are shown first. Secondary units may be shown in parentheses, for information purposes only. These secondary units may or may not be exact equivalents to the primary units. 1.2.2 SI units are provided for all parameters except where there is no direct equivalent such as the units for screw threads, national pipe threads/diameters, and tubing size. 1.2.3 See also A8.1 for clarification; it does not supersede 1.2.1 and 1.2.2. 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. See Annex A1 for general safety precautions. 1.4 Table of Contents: SectionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus6Engine Fluids and Cleaning Solvents7Preparation of Apparatus8Engine/Stand Calibration and Non-Reference Oil Tests9Test Procedure10Calculations, Ratings, and Test Validity11Report13Precision and Bias14AnnexesSafety PrecautionsAnnex A1Intake Air AftercoolerAnnex A2The Cummins ISB Engine Build Parts KitAnnex A3Sensor Locations and Special HardwareAnnex A4External Oil SystemAnnex A5Fuel SpecificationAnnex A6Cummins Service PublicationsAnnex A7Specified Units and FormatsAnnex A8Oil AnalysesAnnex A9
