A prepared copper strip is totally immersed in a sample of grease and heated in an oven or liquid bath at a specified
temperature for a definite period of time. Commonly used conditions are 100 6 1°C (212 6 2°F) for 24 h 6 5 min. At the end of this heating period, the strip is removed, washed, and compared with the Copper Strip Corrosion Standard.

ASTM D4048 Copper Corrosion From Lubricating Grease

‍KN-4048 Copper Corrosion for Grease

Overview   

  KN-4048 Copper Corrosion for Grease conforms to ASTM D4048 Standard Test Method for Detection of Copper Corrosion from Lubricating Grease .This apparatus measures the tendency of lubricating grease to corrode copper under specific static conditions. It may be of some value in predicting possible chemical attack on lubricated parts, such as bearings that contain copper or copper alloys. Such corrosion, for example, can cause premature bearing failures. However, no correlations with actual field service, most of which are under dynamic conditions, have been established. It does not measure either the ability of the lubricant to inhibit copper corrosion caused by factors other than the lubricant itself nor does it measure the stability of the grease in the presence of copper
