发动机油性能和发动机服务分类

[中文适用范围]： 本SAE标准概述了通过汽车制造商联盟（Alliance）、美国石油协会（API）、美国材料与试验协会（ASTM）、发动机制造商协会（EMA）、国际润滑剂规格咨询委员会（ILSAC）和SAE的努力开发的发动机油性能类别和分类。API和ASTM的口头描述以及规定的测试方法和限制在表1中显示了活性类别，在表A1中显示了过时类别。附录A因此是对过时类别的历史记录。 在本文件的目的中，活性类别定义为那些（a）所需的测试设备和测试支持材料（包括参考发动机油和参考燃料）容易获得，或者类别生命周期监督小组已经建立了不可用测试和较新的可用测试之间的等效性；（b）ASTM或测试开发人员监控所有测试的精确度；（c）在撰写时可通过API EOLCS获得许可。 启动新分类的当前流程是通过Alliance、API、ASTM、EMA、ILSAC和SAE的合作努力开发的。新的ILSAC分类是使用API 1509附录C中定义的程序开发的。新的API“C”类别是使用API 1509附录D中定义的程序添加的。新的API“S”类别是由API润滑剂组添加的。 [外文原描述]： This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the Alliance of Automobile Manufacturers (Alliance), American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), the Engine Manufacturers Association (EMA), the International Lubricant Specification Advisory Committee (ILSAC), and SAE. The verbal descriptions by API and ASTM, along with prescribed test methods and limits, are shown for active categories in Table 1 and obsolete categories in Table A1 . Appendix A is thus a historical documentation of the obsolete categories.For purposes of this document, active categories are defined as those (a) for which the required test equipment and test support materials, including reference engine oils and reference fuels, are readily available, or for which the Category Life Oversight Group has established equivalencies between unavailable tests and newer, available tests; (b) which ASTM or the test developer monitors precision for all tests; and (c) which are available for licensing by API EOLCS at time of writing.The current processes for initiating new classifications were developed through the cooperative efforts of the Alliance, API, ASTM, EMA, ILSAC, and SAE. New ILSAC classifications are developed using the procedure defined in API 1509 Annex C. New API “C” categories are added using the procedure defined in API 1509 Annex D. New API “S” categories are added by the API Lubricants Group.Cross Reference: ASTM STP 315,ASTM STP 509,ASTM7156,ASTMD130,ASTMD2887,ASTMD4485,ASTMD4683,ASTMD4684,ASTMD4814,ASTMD4951,ASTMD5133,ASTMD5293,ASTMD5302,ASTMD5480,ASTMD5533,ASTMD5800,ASTMD5844,ASTMD5862,ASTMD5966,ASTMD5967,ASTMD5968,ASTMD6082,ASTMD6202,ASTMD6278,ASTMD6417,ASTMD6483,ASTMD6557,ASTMD6593,ASTMD6594,ASTMD6618,ASTMD6681,ASTMD6709,ASTMD6750,ASTMD6794,ASTMD6795,ASTMD6838,ASTMD6891,ASTMD6896,ASTMD6922,ASTMD6923,ASTMD6975,ASTMD6984,ASTMD6985/D6987M,ASTMD7097,ASTMD7109,ASTMD7216,ASTMD7320,ASTMD7422,ASTMD7468,ASTMD7484,ASTMD7528,ASTMD7549,ASTMD7563,ASTMD7589,ASTMD892,ASTMD92,ASTMD93,ASTME178,J1297_201710,J1423_201502,J300_201304,J304_201606,J312_201902,J357_201601
