Standard Test Method for Evaluation of the Thermal and Oxidative Stability of Lubricating Oils Used for Manual Transmissions and Final Drive Axles

SCOPE
1.1 This test method is commonly referred to as the L-60-1 test. 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 the standard except for the catalyst weight loss and oil weight measurements, for which the unit is millilitre; the alternator output, for which the unit is watt; and the air flow, for which the unit is milligram per minute. The SI values in parentheses are for information only.  
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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard information is given in Sections 7 and 8, and Annex A3.
