ASTM D4048 - Copper Corrosion from Lubricating Grease


We perform grease quality and conformance testing by ASTM D4048 to measure how corrosive lubricating grease is to copper. A strip of copper is immersed in the grease sample at a specific temperature for a period of time. (Times and temperatures can vary.) At the end of the test the copper is washed and examined for corrosion.

We also perform copper corrosion testing by ASTM D1275ASTM D130DIN 51811FTM 5305IP 315ISO 2160ISO 5662MIL-PRF-372E §4.3.2, and MIL-PRF-46002 § These different test methods use different instruments or procedures or are used for certain sample types.
