(Test Method)Standard Test Method for Evaluation of Automotive Engine Oils for Valve-Train Wear Performance in Cummins ISB Medium-Duty Diesel Engine
Standard Test Method for Evaluation of Automotive Engine Oils for Valve-Train Wear Performance in Cummins ISB Medium-Duty Diesel Engine
SIGNIFICANCE AND USE
5.1 This test method was developed to assess the performance of a heavy-duty engine oil in controlling engine wear under operating conditions selected to accelerate soot production and valve-train wear in a turbocharged and aftercooled four-cycle diesel engine with sliding tappet followers equipped with exhaust gas recirculation hardware.
5.2 The design of the engine used in this test method is representative of many, but not all, modern diesel engines. This factor, along with the accelerated operating conditions, shall be considered when extrapolating test results.
SCOPE
1.1 This test method, commonly referred to as the Cummins ISB Test, covers the utilization of a modern, 5.9 L, diesel engine equipped with exhaust gas recirculation and is used to evaluate oil performance with regard to valve-train wear.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exceptions—SI units are provided for all parameters except where there is no direct equivalent such as the units for screw threads, National Pipe Threads/diameters, tubing size, or where there is a sole source of supply equipment specification.
1.2.2 See also A8.1 for clarification; it does not supersede 1.2 and 1.2.1.
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 A1 for general safety precautions.

INTRODUCTION
Any properly equipped laboratory, without outside assistance, can use the procedure described in

this test method. However, theASTMTest Monitoring Center (TMC) provides reference oils and an
assessment of the test results obtained on those oils by the laboratory. By these means, the laboratory
will know whether its use of the test method gives results statistically similar to those obtained by
other laboratories. Furthermore, various agencies require that a laboratory utilize theTMC services in
seeking qualification of oils against specifications. For example, the U.S. Army imposes such a
requirement in connection with several Army engine lubricating oil specifications.
Accordingly, this test method is written for use by laboratories that utilize the TMC services.
