• Số trang / Page: 34
• Phạm vi áp dụng / Scope of standard: 1.1 This test method describes a two-stroke cycle diesel engine test procedure for evaluating engine oils for certain high-temperature performance characteristics, particularly cylinder liner scuffing and piston ring face distress, but also including port plugging, slipper bushing, and piston skirt distress. Such oils include both single viscosity SAE grade and multiviscosity SAE grade oils used in diesel engines. It is commonly known as the 6V92TA test. (See Note 1.) Note 1 - Companion test methods used to evaluate other engine oil performance characteristics for specification requirements are discussed in Engine Oil tests-SAE J304. 1.2 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 - Where there is no direct SI equivalent, such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. Also, many of the figures still show inch-pound units. 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 hazard statements are given in Sections 8, 10, 13, and 14. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exceptions - Where there is no direct SI equivalent such as screw threads, National Pipe Threads/diameters, tubing size, or single source supply equipment specifications. 1.5 This test method is arranged as follows: SectionScope1Referenced Documents2Terminology3Summary of Test Method4Significance and Use5Apparatus-General Description6Apparatus-Laboratory and Test Stand Requirements7Apparatus-Test Engine8 Test Engine8.1 Engine Parts8.2 Special Cleaning Procedures8.3 Periodic Maintenance Inspections8.4 Engine Build-up Procedures8.5Measurement Instrumentation9 Temperatures9.1 Pressures9.2Reagents and Materials10 Test Fuel10.1 Test Oil10.2 Coolant10.3 Sealing and Anti-seize Compounds10.4Hazards11Laboratory and Test Stand Calibration12Test Procedure13 Pre-Test Procedure13.1 Engine Operating Procedure13.2 Periodic Measurements and Functions13.3 Diagnostic Data Review13.4 End of Test Procedure13.5Interpretation of Test Results14 Parts Rating Area-Environment14.1 Piston Rings14.2 Cylinder Liner14.3 Piston Pin Slipper Bushing14.4 Rocker Arm Bushing14.6 Referee Rating14.7Preparation of Report15 Test Numbering15.1 Operational Data15.2 Photographs15.3 Electronic Transmission of Test Results15.4Precision and Bias17Keywords18AnnexesASTM Test Monitoring CenterAnnex A1Detailed Specifications and Drawings of ApparatusAnnex A2Engine Part Number ListingAnnex A3Test Fuel AnalysisA3.1Report FormsAnnex A5Data DictionaryAnnex A6AppendixesOil Producer's AffidavitAppendix X1Engine Build-up FormsAppendix X2
