• Copper Strip Corrosion from Lubricating Grease

Copper Strip Corrosion from Lubricating Grease

Measures the tendency of lubricating grease to corrode copper under static conditions. A polished copper strip is immersed in a sample of grease at elevated temperature for a specified period. The strip is examined for corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM Copper Strip Corrosion Standards.

  • Conforms to ASTM D4048 and related specifications
