Crack: May be encountered with hard coating materials that are applied hot then shrink as they cool or a coating that has been damaged. Cracks can be at an angle and the distance between the electrode and the substrate will be greater, needing a higher voltage to jump the gap.

Blowhole: Formed as the coating cools, normally over welds or trapped air coming from a ‘two-part’ coating as it cures. The blowhole may not go through to the substrate and will only be detected if the test voltage is high enough to break down the remaining coating material.

Burr: Burrs on welds, or holes in the substrate reduce the coating thickness to a point where the test voltage exceeds the dielectric strength of the coating and it breaks down.

Air bubble: Trapped air will only be detected when the test voltage is high enough to break down the remaining coating. i.e. to find air bubbles greater than half the coating thickness the test voltage would need to be at least half the dielectric strength of the total coating thickness.

Inclusion: Dirt, dust, even flies that get trapped as coatings are applied. If the inclusion is non-conductive and the coating bonds to it, it may not be detected; again the test voltage will need to break down any coating covering the inclusion.
