|Standards||ASTM D 130|
Copper strip corrosion is a method for determining levels of corrosion protection in lubricants, as well as detecting the presence of corrosive products, such as sulfur compounds.
Polished lengths of copper stips are partially immersed in the samples for a set time-frame and temperature. After completion of the test cycle, each strip is compared with a set of test samples to determine it’s classification number.
An ASTM classification number of 1-4 is given, depending on the condition of the strip post-testing.
