One crucial method employed to assess a lubricant’s ability to protect copper and non-ferrous metals is copper corrosion testing.
Understanding the Copper Corrosion Testing
Definition and Purpose
A copper corrosion strip test is performed to determine a lubricant’s capability to protect copper and copper-containing alloys from corrosion or staining. The test results are also indicative of a lubricant’s corrosion protection properties with other non-ferrous metals such as aluminum.
Significance
This test holds significance in determining a lubricant’s suitability for use in machinery where copper’s non-ferrous corrosion could degrade the operational effectiveness of machine components. It provides valuable insights into a lubricant’s protective capabilities, guiding manufacturers and users in selecting the most appropriate lubricant.
Navigating the Testing Process
Conducting the copper corrosion test involves immersing a cleansed copper strip in the test lubricant and subjecting it to elevated temperatures, typically around 100°C, for a specified duration, commonly 24 hours. The resulting appearance of the copper strip is then compared to an ASTM* copper strip corrosion standard, and the lubricant receives a rating based on its corrosion protection capability.

Deciphering the Results
The ASTM copper strip corrosion standard categorizes lubricants based on their corrosion protection capabilities, ranging from 1a and 1b, denoting superior performance, to successive numbers like 2, 3, and 4, indicating weaker capabilities. Understanding these ratings is crucial for selecting the most suitable lubricant for specific industrial applications.
