1、Designation: D4485 16D4485 18Standard 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 la
2、st 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

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 inma

Where applicable, candidate oil programs are conducted inaccordance with theAmerican Chemistry Council (ACC) PetroleumAdditives ProductApproval Codeof Practice.Other servic
7、e 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 inclu
8、ded 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 tes
9、t 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 exclu
10、ded 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 wit

In addition, when assessing oil performance, it is desirable that the oil be evaluated underactual operating conditions.1 This

18、 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5.1 Exceptions:1.5.1.1 The roller follower shaft wear in Test Method D5966 is in mils.1.5.1.2 The oil consumption in Test Method D6750 is in grams per kilowatthour.NOTE 1The k
19、Wh unit is deprecated. The preferred SI unit is the joule (J); 1 kWh = 3.6 MJ.1.5.1.3 The bearing wear in Test Method D6709 is in grams and is described as weight loss, a non-SI term.1.5.1.4 Some of the appendixes are verbatim from other sources, and non-SI units are included.1.6 This international
