ASTM D6594 - 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.
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.
