  • Patent number: 5610068
    Abstract: A method for determining the adequacy of corrosion prevention treatments applied to metal surfaces is disclosed. The method provides a qualitative determination of corrosion detection using inexpensive equipment. Generally, the method encompasses wetting at least a first and a second absorbent patches capable of retaining a liquid corrosive to metal surfaces to be tested with the corrosive liquid to obtain wetted patches and then contacting a portion of a first metal surface to be tested with the first patch under corrosive conditions and contacting a portion of a second metal surface to be tested with the second patch, wherein the second metal surface having the same composition as the first metal surface has been treated with an effective amount of a corrosion prevention treatment and subjecting the second patch in contact with the second metal surface to the same corrosive conditions as the corrosive conditions applied to the first patch in contact with the first metal surface.
