Passivation Test Kit

The copper sulfate test is intended to test the effectiveness of passivation. It can also be used to determine if there is a need for passivation.

The purpose is used to find the presence of free iron which is usually induced onto the surface of a part during fabrication, transportation, polishing, etc.

The principle of the test is based on an oxidation-reduction which causes the dissolved copper ions to deposit or plate out onto the free iron particles.
