scope:
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.2 This test method is commonly referred to as the Mack T-12
This test method also provides the procedure for running an abbreviated length test, which is commonly referred to as the T-12A. The procedures for the T-12 and T-12A are identical with the exception of the items specifically listed in Annex A9. Additionally, the procedure modifications listed in Annex A9 refer to the corresponding section of the T-12 procedure
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard
Exception-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
This standard does not purport to address all of the safety concerns, if any, associated with its use.
