Methods and apparatuses are provided for creation of discrete corrosion defects with a wide range of diameter to depth aspect ratios for painted test standards. Also provided are methods for use of those test standards to characterize the corrosion under paint detection threshold, statistical reliability, and accuracy of NDI and/or NDT techniques including but not limited to flash thermography, ultrasonic testing, eddy current testing, microwave testing, shearography, and infrared testing.

1. A method for characterizing nondestructive testing (NDT) method's detection sensitivity and threshold performance for corrosion detection, comprising providing at lease one corrosion NDT test standard containing discrete corrosion defects, testing said corrosion NDT test standard with said NDT method, and characterizing said NDT method's detection sensitivity and threshold performance based on said NDT method's detection of corrosion defects in said at least one NDT test standard. 2. The method of claim 1, wherein said at least one NDT test standard comprises at least one coated substrate. 3. The method of claim 1, wherein said discrete corrosion defects are known as to at least one property selected from the group consisting of size, shape, location, chemistry, and morphology of corrosion defect. 4. The method of claim 2, wherein said substrate is made of a material selected from the group consisting of aluminum, aluminum alloy, steel, steel alloy, and a metal alloy that is subject to corrosion. 5. The method of claim 1, wherein said NDT system is selected from the group consisting of ultrasonic testing, flash thermography, eddy current testing, microwave testing, shearography, radiography, and infrared testing. 6. The method of claim 2, wherein said coating on said coated substrate is selected from to the group consisting of organic coating polymers epoxy, acrylic, urethane, latex, enamel paint, inorganic coatings, metals, alloys, ceramics, and combinations thereof.
