1、Designation: D 4485 07An American National StandardStandard Specification forPerformance of Engine Oils1This standard is issued under the fixed designation D 4485; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last re
2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.INTRODUCTIONThis specification covers all the currently
3、 active American Petroleum Institute (API) engine oilperformance categories that have been defined in accordance with theASTM consensus process.Thereare organizations with specifications not subject to the ASTM consensus process, such as theInternational Lubricant Standardization and Approval Commit
4、tee (ILSAC), American PetroleumInstitute (API SM Specification), and the Association des Constructeurs Europeans dAutomobiles(ACEA). Certain of these specifications, which have been defined primarily by the use of currentASTM test methods, have also been included in the Appendix of this document for
5、 information.In the ASTM system, a specific API designation is assigned to each category. The system isopen-ended, that is, new designations are assigned for use with new categories as each new set of oilperformance characteristics are defined. Oil categories may be referenced by engine builders inm
6、aking lubricant recommendations, and used by lubricant suppliers and customers in identifyingproducts for specific applications. Where applicable, candidate oil programs are conducted inaccordance with theAmerican Chemistry Council (ACC) PetroleumAdditives ProductApproval Codeof Practice.Other servi
7、ce categories not shown in this document have historically been used to describe engineoil performance (SA, SB, SC, SD, SE, SF, SG and CA, CB, CC, CD, CD-II, CE) (see 3.1.2). SA isnot included because it does not have specified engine performance requirements. SG is not includedbecause it was a cate
8、gory that could not be licensed for use in the API Service Symbol after Dec. 31,1995. The others are not included because they are based on test methods for which engine parts, testfuel, or reference oils, or a combination thereof, are no longer available. Also, the ASTM 5-Car andSequence VI Procedu
9、res are obsolete and have been deleted from the category Energy Conserving andEnergy Conserving II (defined by Sequence VI). Information on excluded older categories andobsolete test requirements can be found in SAE J183.1. Scope1.1 This specification covers engine oils for light-duty andheavy-duty
10、internal combustion engines used under a variety ofoperating conditions in automobiles, trucks, vans, buses, andoff-highway farm, industrial, and construction equipment.1.2 This specification is not intended to cover engine oilapplications such as outboard motors, snowmobiles, lawnmowers, motorcycle
11、s, railroad locomotives, or ocean-goingvessels.1.3 This specification is based on engine test results thatgenerally have been correlated with results obtained on refer-ence oils in actual service engines operating with gasoline ordiesel fuel. As it pertains to the API SL engine oil category, itis ba
12、sed on engine test results that generally have beencorrelated with results obtained on reference oils run ingasoline engine Sequence Tests that defined engine oil catego-ries prior to 2000. It should be recognized that not all aspectsof engine oil performance are evaluated by the engine tests inthis
13、 specification. In addition, when assessing oil performance,it is desirable that the oil be evaluated under actual operatingconditions.1.4 This specification includes bench and chemical tests thathelp evaluate some aspects of engine oil performance notcovered by the engine tests in this specificatio
