Cans 8. Copper Sulfate Test
This method determines whether there are any exposed metal surfaces on the interior of containers coated with a polymer material. It is designed primarily for the testing of aluminum cans and ends coated with internal coating (IC), but it can be used for containers made with other metals such as steel. A galvanic reaction occurs when the copper from the copper sulfate is deposited on the surface in locations where the surface is not covered with IC. This method detects potential pinholes and pores in the IC or places where the container may contain improper coverage of the IC on the interior.
