1、Designation: D4485 18D4485 18aStandard Specification forPerformance of Active API Service Category Engine Oils1This standard is issued under the fixed designation D4485; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of l
2、ast revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.INTRODUCTIONThis specification covers all the
3、 currently 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 Appro
4、val Committee (ILSAC), American PetroleumInstitute (API SM, SN Specifications), and the Association des Constructeurs EuropeansdAutomobiles (ACEA). Certain of these specifications, which have been defined primarily by the useof current ASTM test methods, have also been included in the Appendixes 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, SH and CA, CB, CC, CD, CD-II, CE, CF, CF-2, CF-4,CG-4) (see 3.1.2). SA is not included because it does not have specified engine performancerequirements. SH is not incl
8、uded because it was a category that could not be licensed for gasolineengine oil use in the API Service Symbol after Dec. 2, 2010. (NoteThe SH category has beenincluded in Appendix X8 as relevant information in combination with “C” categories.) The others arenot included because they are based on te
9、st methods for which engine parts, test fuel, or reference oils,or a combination thereof, are no longer available.Also, theASTM 5-Car and Sequence VI Proceduresare obsolete and have been deleted from the category Energy Conserving and Energy Conserving II(defined by Sequence VI). Information on excl
10、uded older categories and obsolete test requirementscan be found in SAE J183.1. Scope*1.1 This specification covers engine oils for light-duty and heavy-duty internal combustion engines used under a variety ofoperating conditions in automobiles, trucks, vans, buses, and off-highway farm, industrial,
11、 and construction equipment.1.2 This specification is not intended to cover engine oil applications such as outboard motors, snowmobiles, lawn mowers,motorcycles, railroad locomotives, or oceangoing vessels.1.3 This specification is based on engine test results that generally have been correlated wi
12、th results obtained on reference oilsin actual service engines operating with gasoline or diesel fuel.As it pertains to theAPI SLengine oil category, it is based on enginetest results that generally have been correlated with results obtained on reference oils run in gasoline engine Sequence Tests th
13、atdefined engine oil categories prior to 2000. It should be recognized that not all aspects of engine oil performance are evaluatedby the engine tests in this specification. In addition, when assessing oil performance, it is desirable that the oil be evaluated underactual operating conditions.1 This
