The frequency of and type of testing must take into account <br /> container size and design (such as floating roof, skid mounted, elevated, or partially <br /> buried). You must combine visual inspection with another testing technique such as <br /> hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, <br /> or another system of nondestructive shell testing. You must keep comparison records <br /> and you must also inspect the container's supports and foundations.

Records of inspections and tests <br /> kept under usual and customary business practices will suffice for purposes of this <br /> Paragraph. <br /> Metal thickness testing was performed utilizing a certified Danatronics EHC-09DL- ',... <br /> CW Digital Ultrasonic thickness gauge. Calibration of the testing unit was performed <br /> on May 5, 2015, prior to conducting certified non-destructive metal thickness testing. <br /> Testing consisted of A point measurements per square foot.
