ASTM D7583 Standard Test Method for John Deere Coolant Cavitation Test
1. Scope
1.1 This test method is commonly referred to as the John Deere Cavitation Test. 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 parenthesis 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.

3. Terminology
3.1 Definitions:
3.1.1 blind reference coolant, n - a reference coolant, the identity of which is unknown by the test facility.

3.1.2 blowby, n - in internal combustion engines, the combustion products and unburned air-and-fuel mixture that enter the crankcase.

3.1.3 calibrate, v - to determine the indication or output of a measuring device with respect to that of a standard.

3.1.4 heavy-duty, adj - in internal combustion engine operation, characterized by average speed, power output, and internal temperatures that are close to the potential maximum.

3.1.5 heavy-duty engine, n - in internal combustion engines, one that is designed to allow operation continuously at or close to its peak output.

3.1.6 non-reference coolant, n - any coolant other than a reference coolant, such as a research formulation, commercial coolant or candidate coolant.

3.1.7 non-standard test, n - a test that is not conducted in conformance with the requirements in the standard test method; such as running in an non-calibrated test stand or using different test equipment, applying different equipment assembly procedures, or using modified operating conditions.

3.1.8 reference coolant, n - a coolant of known performance characteristics, used as a basis for comparison.

3.1.9 test coolant, n - any coolant subjected to evaluation in an established procedure.

3.1.10 wear, n - the loss of material from, or relocation of material on, a surface. Discussion - Wear generally occurs between two surfaces moving relative to each other, and is the result of mechanical or chemical action or by a combination of mechanical and chemical actions.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 cylinder liner, n - in internal combustion engines, the replaceable cylinders in which the pistons move up and down and combustion takes place.

3.2.2 overhead, n - in internal combustion engines, the components of the valve train located in or above the cylinder head.

3.2.3 valve train, n - in internal combustion engines, the series of components, such as valves, crossheads, rocker arms, push rods and camshaft, that open and close the intake and exhaust valves.
