1.1 This test method is commonly referred to as the John Deere Cavitation Test.2 The test method defines a heavy-duty diesel engine to evaluate coolant protection as related to cylinder liner pitting caused by cavitation.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. The only exception is where there is no direct SI equivalent such as screw threads, national pipe threads/diameters, and tubing sizes.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Annex A1 for general safety precautions.
