The determination of the corrosiveness of grease is to examine whether the grease has a corrosive effect on the metal;
Determination of the compatibility and swelling of grease with synthetic rubber, the compatibility of rubber with rubber parts can be evaluated according to the changes in volume and hardness of synthetic rubber before and after the test;
By measuring the contact resistance value of the grease, the influence of the grease on the change in the contact resistance can be evaluated.
