ActiveLubricating grease--Corrosiveness to copper--Copper strip test
润滑脂铜片腐蚀试验法
Application Summary AI generated
This standard specifies a test method for determining the corrosiveness of lubricating grease to copper by observing the discoloration of a polished copper strip after immersion in the grease at a controlled temperature. It is applied in the petroleum and lubrication industries to evaluate the chemical stability and compatibility of greases with copper-containing components, such as bearings and electrical contacts. The test is critical for quality control and product selection in automotive, industrial machinery, and aerospace applications where copper corrosion could lead to equipment failure.
