The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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 and health practices and determine the applicability of regulatory limitations prior to use. See Annex A1 for general safety precautions.

Significance and Use
5.1 This test method was developed to evaluate the ability of a heavy-duty diesel engine coolant to provide protection against damage resulting from a phenomenon known as cylinder liner cavitation corrosion.
5.2 This test method may be used for engine coolant specification acceptance when all details of this test method are in compliance.
5.3 The design of the engine used in this test method is a production OEM diesel engine modified to consistently produce the operating conditions that accelerate damage from cylinder liner cavitation. This factor, along with the accelerated operating conditions needs to be considered when extrapolating test results.
