1.1 该测试方法通常被称为L-60-1测试。 2 它涵盖了汽车手动变速器和最终驱动桥润滑油在高温氧化条件下的油增稠、不溶物形成和沉积物形成特性。 1.2 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.2.1 例外情况- 催化剂质量损失、油质量和体积、交流发电机输出和空气流量的SI单位值应视为标准值。 1.2.2 为所有参数提供了SI单位，除非没有直接等效的单位，如螺纹单位，或者只有源供应设备规格。1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 具体警告信息在章节中给出 7 和 8 和 Annex A7 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 本试验方法测量汽车手动变速器和终传动润滑油在高-温度条件，导致厚厚的油、油泥、碳和清漆沉积，并形成腐蚀产物。这种劣化可能导致严重的设备性能问题，尤其包括由于轴-密封界面处的沉积物形成而导致的密封失效。该测试方法用于筛选润滑剂中有问题的添加剂和基础油的这些趋势。 5.2 以下文件中使用或引用了该试验方法: 5.2.1 美国石油协会(API)出版物1560-汽车手动变速器、手动变速驱动桥和车轴的润滑剂服务名称， 7 5.2.2 STP-512A-用于API GL-5服务的汽车齿轮润滑剂的实验室性能测试， 8 5.2.3 SAE J308-关于车轴和手动变速器润滑油的信息报告， 9 和 5.2.4 美国军用规范MIL-L-2105D。

1.1 This test method is commonly referred to as the L-60-1 test. 2 It covers the oil-thickening, insolubles-formation, and deposit-formation characteristics of automotive manual transmission and final drive axle lubricating oils when subjected to high-temperature oxidizing conditions. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 Exceptions— The values stated in SI units for catalyst mass loss, oil mass and volume, alternator output, and air flow are to be regarded as standard. 1.2.2 SI units are provided for all parameters except where there is no direct equivalent such as the units for screw threads, or where there is a sole source supply equipment specification. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning information is given in Sections 7 and 8 and Annex A7 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method measures the tendency of automotive manual transmission and final drive lubricants to deteriorate under high-temperature conditions, resulting in thick oil, sludge, carbon and varnish deposits, and the formation of corrosive products. This deterioration can lead to serious equipment performance problems, including, in particular, seal failures due to deposit formation at the shaft-seal interface. This test method is used to screen lubricants for problematic additives and base oils with regard to these tendencies. 5.2 This test method is used or referred to in the following documents: 5.2.1 American Petroleum Institute (API) Publication 1560-Lubricant Service Designations for Automotive Manual Transmissions, Manual Transaxles, and Axles, 7 5.2.2 STP-512A–Laboratory Performance Tests for Automotive Gear Lubricants Intended for API GL-5 Service, 8 5.2.3 SAE J308-Information Report on Axle and Manual Transmission Lubricants, 9 and 5.2.4 U.S. Military Specification MIL-L-2105D.
