ASTM D6594-20e1
(Test Method)Standard Test Method for Evaluation of Corrosiveness of Diesel Engine Oil at 135 °C
Standard Test Method for Evaluation of Corrosiveness of Diesel Engine Oil at 135 °C
SIGNIFICANCE AND USE
5.1 This test method is intended to simulate the corrosion process of non-ferrous metals in diesel lubricants. The corrosion process under investigation is that believed to be induced primarily by inappropriate lubricant chemistry rather than lubricant degradation or contamination. This test method has been found to correlate with an extensive fleet database containing corrosion-induced cam and bearing failures.3
SCOPE
1.1 This test method covers testing diesel engine lubricants to determine their tendency to corrode various metals, specifically alloys of lead and copper commonly used in cam followers and bearings.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
1.4 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.

INTRODUCTION
Any properly equipped laboratory, without outside assistance, can use the procedure described in
2
this test method. However, theASTM Test Monitoring Center (TMC) provides reference oils and an
assessmentofthetestresultsobtainedonthoseoilsbythelaboratory(seeAnnexA1).Bythesemeans,
the laboratory will know whether their use of the test method gives results statistically similar to those
obtainedbyotherlaboratories.Furthermore,variousagenciesrequirethatalaboratoryutilizetheTMC
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.
Laboratories that choose not to use those services may simply ignore those portions of the test method
that refer to the TMC.
This test method may be modified by means of information letters issued by the TMC. In addition,
the TMC may issue supplementary memoranda related to the method (see Annex A1). For other
