NDI stands for what in maintenance terminology?

• A. Non destructive integrity
• B. Non destructive inspection
• C. Nondestructive testing
• D. Not destructive inspection

Answer: (B)

NDI stands for Non destructive inspection. The key idea is to assess a component’s condition without causing any damage, so it can continue to operate while you check for issues like cracks, corrosion, wear, or thickness loss. A variety of methods can be used within NDI, including visual inspection, ultrasonic testing, radiography, magnetic particle, dye penetrant, eddy current, and infrared thermography. The emphasis is on evaluating integrity through inspection, not on taking the part apart or destroying it for testing. While nondestructive testing (NDT) is related and refers to the broader set of nondestructive techniques used to obtain material data, the term NDI specifically highlights the inspection process used to determine whether the part is still fit for service. The other options either describe phrases that aren’t standard in maintenance terminology or mix up the focus between testing and inspection.
