SIGNIFICANCE AND USE
5.1 There are several major causes of automotive lubricant-related seal failures. This test method addresses only those failures caused by excessive elastomer hardening, elongation loss, and volume swell and attempts to determine the likelihood that an oil might cause premature sealing system failures in field use. This test method may be used as a requirement of a performance specification, such as Specification D5760 and J2360.
5.2 Another major cause of seal failure is the formation of carbon, varnish, and sludge-like deposits on the seal lip. The deposit-forming characteristics of automotive gear oils are evaluated in Test Method D5704. That procedure is intended in part to evaluate the potential for oils to cause premature seal failure in field service.
SCOPE
1.1 This test method2 covers the determination of the compatibility of automotive gear oils with specific nitrile, polyacrylate, and fluoroelastomer oil seal materials.
1.2 Users of this test method should obtain Test Methods D412, D471, and D2240 and become familiar with their use before proceeding with this test method.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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