Abstract
A method of testing coating integrity of containers includes the steps of introducing a probe into an electrolytic solution into the container and applying a constantly-increasing voltage to the probe from a source and taking readings of the voltage when the current flow through the container reaches a predetermined level. The apparatus also includes a gripping mechanism for producing a positive contact between the metal in the container and the remainder of the circuit.
