Test Method:
Dip one prepared copper strip into lubricating grease sample completely,and heat it in oven or liquid bath for a period of time.Usually the adopted condition is 100ºC and 25 hours. When the test is finished, take out the copper strip to wash.Method A is comparing the test copper strip and standard color plate of corrosion strip to confirm the corrosion grade.Method B is checking if the color is changed.
