    1.1This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including viscosity increase and soot concentrations (loading).2 This test method is commonly referred to as the Mack T-8.

    1.2This test method also provides the procedure for running an extended length T-8 test, which is commonly referred to as the T-8E and an abbreviated length test, which is commonly referred to as T-8A. The procedures for the T-8E and the T-8A are identical to the T-8 with the exception of the items specifically listed in Annex A8 and Annex A9 respectively. Additionally, the procedure modifications listed in Annex A8 and Annex A9 refer to the corresponding section of the T-8 procedure.

    1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3.1Exceptions—Where there is no direct SI equivalent such as the units for screw threads, National Pipe Threads/diameters, tubing size, sole source equipment suppliers, and oil consumption in grams per kilowatt-hour.

    1.4This 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.
