Abstract
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.
