1.1 This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including lead corrosion and wear of piston rings and cylinder liners in an engine equipped with exhaust gas recirculation and running on ultra-low sulfur diesel fuel. This test method is commonly referred to as the Mack T-12.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.2.1 Exception<\/span><\/span> Where there is no direct SI equivalent, such as the units for screw threads, National Pipe Threads\/diameters, tubing size, and single source supply equipment specifications.<\/p>\n

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. See Annex A6 for specific safety precautions.<\/span><\/span><\/p>\n
