Standard Test Method for Evaluation of the Thermal and Oxidative Stability of Lubricating Oils Used for Manual Transmissions and Final Drive Axles
The following bibliographic material is provided to assist you with your purchasing decision:
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 gram; the oil volume, 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 other SI values, which are 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 warning information is given in Sections 7 and 8 and Annex A3.
Significance and Use
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.
